I use technology to revitalize the underworld

[Lord Dalke]: So you don't know yet.Every trader can sign a plane trade contract.The content of the contract is supervised by the system, and no matter which party breaches the contract, it will be punished by the system.

[Lord Dalke]: Unless the plane system is no longer used in this life, this punishment is inevitable.It’s just that for such a contract, both parties must pay a 5% handling fee to the system.

[Lord Dalke]: As long as you are willing, I can bear all the handling fees.

Feng Jingchen really didn't know this rule.

He flipped through the plane system, and sure enough, he found a [Trading Guide] in the corner of the personal information page.This type of transaction is indeed documented above.

So Feng Jingchen no longer hesitated.

[Successor of Socialism]: Can you make energy batteries?We barter, it should be more affordable.

[Lord Dalke]: Yes!How about seven tertiary energy batteries for 5 grams of secondary shady soil?

Feng Jingchen was naturally fine.

Calculated in this way, he could earn 1 points by selling 1.4 gram of second-level Yin soil to Lord Dalk, which is a full 4 points higher than the purchase price of the system!

Coupled with the almost free large-scale energy compression device, Feng Jingchen is sure to make a profit on this deal.

Soon, Feng Jingchen negotiated and signed the contract with Lord Dalk.

But the deal didn't come through immediately.

With such a large compression device, it is impossible for Lord Dalk to have it in stock, and it needs to be refined from scratch.

It will take about two months, and it will arrive almost in October.

This was also agreed in the contract, if Lord Dalk delays, Feng Jingchen can also get compensation.

Fortunately, he is not in a hurry for the time being.

Anyway, there are not many things in the underworld now, only the first level of Yin soil is the most.It's okay to continue to sell more, but it can't be regarded as a long-term pillar industry.

After the contract was signed, Feng Jingchen was thinking about the future industrial upgrading and development of the prefecture, and was preparing to go offline.

But Lord Dalk suddenly sent a message: [My good friend.If you have any spare Secondary Shade you want to sell, do so anonymously.Otherwise, offending the stock god gang will bring you some unnecessary troubles. 】

After saying this, Lord Dalk didn't explain, and the portrait went dark.

Feng Jingchen couldn't help raising his brows slightly.

Lord Dalk's words obviously knew that Feng Jingchen still had extra Yin soil, but he would never agree to sell them all to him.

And not only did he not force it, but he also thoughtfully reminded Feng Jingchen who looked like a pure rookie.

He sent this passage, regardless of whether Feng Jingchen had realized it before, it would definitely increase his favorability.

Feng Jingchen saw through Lord Dalk's intentions, but he also accepted the love in his heart.

After these two conversations, Feng Jingchen also felt that Lord Dalk was a good person.If you can, develop a trader friend, and the advantages far outweigh the disadvantages.

Feng Jingchen lowered his eyes and pondered for a while, and quickly sorted out all his thoughts.

Feng Jingchen does not plan to sell the second-level Yin soil to the outside world until it is confirmed that it can be mass-produced.

But as long as the conditions are sufficient, Feng Jingchen is not afraid of the mob of the God of Stocks Gang.

Feng Jingchen restrained his thoughts, replaced the small energy compression device with a new battery, and then turned off the plane system.

Just at this time, Yan Wangyin flew back with two fragments of the evil mirror stand: "Chenchen, I have searched for those outside the ghost gate~ I found this one."

It threw two fragments into Feng Jingchen's arms: "But it seems that these two fragments are not connected, take a look~"

Feng Jingchen looked down, and without opening the Eye of Reality, he could clearly see that these were two fragments that were not adjacent to each other.

Because the front of the second fragment is not a smooth mirror surface, but a delicate relief like the decoration around the mirror.

And, of course, the horrifying relief of the exquisite car-cracking ghoul.

Feng Jingchen inspected it several times with the eyes of reality, but he still couldn't gain anything from it.

On the other side, Yan Wangyin had already circled the energy storage box a few times, and said in a sour tone: "This little guy is treated really well. Chenchen, you even made him a nest."

It doesn't even have a small house, hum~!

Xiezhi had regained some vitality at this time.

It ignored the seal of the king of hell at all, held the small beads on its front legs, and faced the direction of the fragments of the evil mirror, eagerly "oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo".

Feng Jingchen looked up at the two little guys, and put the second fragment into the energy storage box.

Xiezhi immediately wailed in excitement, the whole little beast was tucked into the bead, and said "oooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo" at the whole little beast in the bead, don't know what it is talking about.

And Feng Jingchen raised his hand and grabbed the seal of the king of hell who was dripping with sour water: "Thank you for your hard work. When I have time later, I will build you a hall of the king of hell."

"!!!" Yan Wangyin immediately shouted excitedly, "I want the biggest, tallest, most beautiful Yan Wang Palace! I will live with Chen Chen!"

Feng Jingchen looked at the little guy who had been knocked unconscious by the big cake, and a chuckle flashed in his eyes: "Okay."

He handed the first fragment of the evil mirror table to Yan Wangyin: "However, it is still hard for you to make a trip to find the other fragments of the evil mirror table, can you?"

"Leave it on me!" Yan Wangyin was so excited that he couldn't find Bei.Picking up the fragments of the evil mirror table, he rushed out at once!

The unscrupulous King of Hades ordered the "child labor".

After thinking about it, he decided to go back to Yangjian to help Murong Qiao bring back the things he wanted to buy.

Murong Qiao earned more than 100 merits for himself during his last trip to the ghost market.

He spent all the merit points in one go.

I bought two soul-binding ropes and five breath trackers.

With the remaining points, I bought another [-] Yunyin Pills, [-] Xiaobu Pills, and a full [-] catties of Lingyu!

There are so many things, there are nearly [-] bottles of jade bottles containing pills alone!Not to mention the spirit jade.

Feng Jingchen directly pulled a large piece of cloth of unknown nature, and wrapped it all up for Murong Qiao.

It's just that when he returned to the villa room, he found that the entire villa was empty.

Feng Jingchen glanced up and saw a note on the desktop in his room.

Murong Qiao's handwriting is strong and strong, and the strokes of the pen are flying freely: [Ayu, someone from our sect found an evil celestial master's lair in Ningyang, which is quite difficult. Let's go to support it.I'll be back in about two or three days. 】

Feng Jingchen looked at the signature, Murong Qiao just left yesterday.

After thinking about it, he directly stuffed the big bag into the safe in the cloakroom.

It just so happened that Murong Qiao had told him the password before.

Feng Jingchen told Murong Qiao about this on the back of the note left by him, then turned around and walked back to the underworld.

In just a few minutes, nothing has changed in the underworld.

Only Xiezhi was tired of screaming, and now she was stuck to the fragments of the evil mirror, and seemed to have fallen into a deep sleep.

Feng Jingchen observed it with the eyes of reality, and found that although Xiezhi's light cluster was still dim, it was at least much more stable.

And as it exhales and inhales, subtle and imperceptible energy will be sucked into the body, strengthening itself.

Feng Jingchen looked strange.

Xiezhi's mode of absorbing energy between breaths is somewhat similar to his automatic cultivation!

It's a pity that Feng Jingchen's current level is too low to observe the regular operation in Xiezhi's body.

Feng Jingchen lowered his eyes thoughtfully.

Perhaps, he can think of a way to enhance the performance of the Eye of Reality?

Otherwise, if he encounters something of the same higher level in the future, this Eye of Truth is equivalent to half useless...

Goldfinger who was disliked: "..."

Feng Jingchen did whatever he wanted, immediately assembled another table, and began to write and draw on paper.

The main function of the eye of truth is to spy on the truth.Another is energy conversion and utilization.

In terms of energy conversion, the Eye of Reality can directly consume its own energy, so that ordinary people can also use it, which is already good enough.

Feng Jingchen temporarily skipped over.

What he lacks now is that the power of spying is not strong enough!

If you want to strengthen...

Feng Jingchen quickly thought of several formulas and frantically calculated them on paper.

hours later.

There are layers of draft paper on the desktop, and I don't know how many sheets have been consumed.

At this time, Feng Jingchen finally stopped writing.

And the final blueprint he completed was a pair of glasses, which looked almost the same as what Feng Jingchen was wearing now.

It was named "Eye of Reality DLC" by Feng Jingchen.

However, he was not in a hurry to refine it.

Because Feng Jingchen suddenly remembered that Wu Xinghai was fooled into researching the energy observation magic weapon, which actually has some similarities with this one.

Feng Jingchen turned his eyes slightly, and suddenly had a new idea.

He went back to Yangjian again.

The three of Murong Qiao haven't come back yet.

So Feng Jingchen also locked the blueprint in the safe and asked Murong Qiao to help pass it to Wu Xinghai.

Feng Jingchen has a more important plan ahead, so he can't devote himself to the research and development of real glasses for the time being.

That being the case, why not hand over this project to Wu Xinghai.

He is looking forward to what kind of performance Wu Xinghai will have when he independently produces this new type of magic weapon.

I hope that there will be more and more excellent fellows on this road.

Feng Jingchen's thin lips curled slightly, he calmed down his thoughts, and after returning to the underworld, he looked around.

Nearly half of the Wangchuan River outside the Ghost Gate has been dug up.

More than 500 ghosts in the whole underworld work together with very high efficiency.

Feng Jingchen looked around and walked up to the group of service ghosts led by Weng Xiaoshu.

These ghosts have all been burned by the red lotus fire.

At this moment, seeing Feng Jingchen's face, he was terrified reflexively!

Some ghosts even kicked their legs and fainted from fright!

Feng Jingchen: "..."

"Cough." Weng Xiaoshu secretly kicked the fainted guy.

A warm smile was maintained on his face: "Lord Yan, what are your orders?"

Feng Jingchen looked up at her: "Will any of you know how to build walls?"

"Ah?" Weng Xiaoshu looked blankly at her "subordinates".

All the ghosts looked at each other tremblingly, but none of them dared to respond for a long time.

In the end, the group of ghosts looked at each other for a while, shaking their heads in fear and guilt.

Feng Jingchen was not disappointed when he saw this.

He bought a book "Teaching You to Build the Strongest City Wall from Zero" from the system supermarket.

It was written by a master alchemist named Barlow Perkin in a magical plane.

The content of the book claims to be applicable to all planes and compatible with all materials and energies, and it is known as the entry-level divine book of tower defense in all worlds!

Of course, the later advanced level and ultimate level divine books were also written by Barlow Perkin.

Feng Jingchen handed the book to Weng Xiaoshu: "You call some interested people to learn this together. If someone learns it, they can be transferred to be a worker leader, with a daily salary of 10 Yunyin Pills."

Weng Xiaoshu's eyes lit up suddenly, and she quickly assured her courteously: "Don't worry, Lord Yan, I will definitely handle this matter properly for you, beautiful and beautiful!"

Feng Jingchen didn't doubt Weng Xiaoshu's ability, and said again: "I hope that after the Wangchuan River outside Guimenguan is cleaned up, we can start building the city wall for Guimenguan."

According to Yan Wangyin, the previous Guimen Pass was a truly majestic "pass".Even if there is a ghost king attacking, the ghost gate can keep him out of the pass.

But now after years of devastation, only the strongest gate remains in the gate of hell.

Its supporting walls disappeared without a trace.

Now that the yin and yang worlds are undercurrents, and the ghost gate is the first line of defense in the underworld, Feng Jingchen is thinking of repairing it first.

In this way, not only can it block the enemy's attack, but it can also... ahem, cover up its ugliness.

Build it as soon as possible, so that if Nanqiao and his ilk suddenly come to the underworld, there will be a huge pile of rubbish in front of you.

Although Feng Jingchen himself didn't care about face, Yan Wangyin was right about one thing: Hell's face cannot be lost.

Otherwise, if outsiders know the weakness of the underworld...

Feng Jingchen never dared to underestimate the viciousness and greed of the human heart.

When Weng Xiaoshu heard Feng Jingchen's request, she couldn't wait to pat her chest and promise: "Your Majesty Yan, don't worry, the slave family will handle it well, and absolutely no mistakes will delay your affairs!"

Seeing her overly attentive appearance, Feng Jingchen also guessed what she was thinking.

Weng Xiaoshu spent her entire life climbing from the bottom of an actor to the position of the mistress of the president of the Chamber of Commerce, which shows her ambition and ability.

Now that she has become a ghost, how can she be willing to just become an ordinary ghost?

Such a person is also a good temporary helper.

Feng Jingchen had no doubts about the employer: "This book contains many methods to teach you how to extract materials. If you need anything, just go to the sorted garbage to get it."

Most of the garbage dumps in the underworld are actually construction waste after the collapse of the underworld and the heavens, so it doesn't matter if they are used casually.

If it is a real treasure fragment, then relying solely on this book and the current abilities of the ghosts, it is absolutely impossible to melt it away.

Let them take materials at will, maybe they can screen out some real treasures.

Weng Xiaoshu heard Feng Jingchen's trust, her complexion suddenly beamed with joy, and she quickly answered "Yes!"

After answering, she habitually smiled at Feng Jingchen, her style was very moving.

However, Feng Jingchen has never been moved by beauty.

He waved Weng Xiaoshu to start working, and then walked around again.

At the same time, I told the other ghosts about the construction of the city wall, so that they would be prepared if they were interested in changing jobs.

So, in just a few minutes, this new incident was passed back and forth among the ghost crowd a hundred and eighty times!

No matter whether everyone is interested in the new job or not, all the ghosts talk about it over and over again.

Refusing to let go of this boring underworld life, a rare bit of talk!

After Feng Jingchen announced the new decision.

Then he went back to the small square behind the ghost gate and sat cross-legged next to Xiezhi's small table.

Then, open the system supermarket, start screening the products you want, and finally get ready to start the long-planned plan!

But after a while, Feng Jingchen suddenly discovered a blind spot that he hadn't noticed before.

He lightly tapped the light screen: "System, how many levels are there in the plane?"

Light Screen: [Five. 】

Feng Jingchen: "In other words, the highest level is level five."

Their underworld counts as a level one, and the technological level of the fifth level plane should be a level that he can hardly imagine at present.

but…

Feng Jingchen frowned suspiciously: "The products in this supermarket don't seem to be of such high grade?"

He wanted to buy a computer, but when he searched the entire supermarket, it seemed that the most high-tech product was just a smart optical computer.

This is not uncommon in science fiction works. No matter how high the technological content is, it doesn't look like a product of a level 5 technological plane?

Light Screen: [Yes.According to the Ten Thousand Realms Trading Treaty, in order to prevent low-level plane traders from causing irreparable damage to their original civilization after obtaining goods from high-level planes. 】

[All traders can only buy products from a plane one level higher than their own.Also, traders are prohibited from communicating across more than one level. 】

Feng Jingchen heard the words and immediately opened the plane forum.

Sure enough, for all the traders who appeared in the forum, the plane level mark in front of the name was either 1 or 2.

Feng Jingchen lowered his eyes.

From this point of view, all he can see now is just a corner of this plane trading system floating on the water.

interesting.

Feng Jingchen's lips suddenly curled up in excitement.

He lightly tapped on the light screen: "Can I read the Ten Thousand Realms Trading Treaty you mentioned?"

Guang Screen: [Sorry, because the treaty involves higher-level content, you have no right to view it temporarily. 】

It is "temporarily" without rights.

Feng Jingchen: "Then I have to wait for my plane to upgrade before I can see it?"

Light Screen: [Yes.After ascending to the second level, you can view the Ten Thousand Worlds Trading Treaty. 】

Feng Jingchen continued to ask: "How to upgrade that face?"

Light screen: [You can only inquire after becoming a third-order trader. 】

Feng Jingchen: "..."

Fine.

This noodle system is becoming more and more mysterious.

Feng Jingchen did not continue to ask.

To upgrade to the third-tier trader, the transaction volume needs to reach 5000 million.

This number seems very large, but as long as Feng Jingchen's second-level Yintu can be mass-produced, it will be upgraded soon.

So Feng Jingchen was not in a hurry.Instead, continue with your previous plan.

He returned to the system supermarket and spent 50 points to buy the optical computer with the best performance in the supermarket.

A teleportation white light flashed.

In front of Feng Jingchen's eyes was a shoebox-sized clean box with a pure silver body.

As usual, he opened the Eye of Reality to observe, but suddenly he let out a light snort.

At first glance, the box looks like a ball of light!It seems that Feng Jingchen is not capable enough to spy.

But if you take a closer look, you will find that there are actually too many rules stuffed in this small box!

Countless regular lines are all squeezed together to create such an illusion.

After careful identification for a while, Feng Jingchen found that these regular lines were somewhat similar to those on the golden big net!

A few ripples could not help flashing in those black and white eyes.

A thought that had been conjectured for a long time resurfaced in Feng Jingchen's mind.

If this is true, then his next plan will definitely go smoothly!

Feng Jingchen closed the Eye of Reality, and impatiently put his right hand on the surface of the box.

A mechanical sound came out of the box immediately: "A new life substance has been detected. Binding biological information..."

"The binding is successful~! Welcome to use the top-notch intelligent optical brain X8-7008 produced by Kant Corporation! I wish you a happy use~"

I don't know if it's because of the plane system.

All the products that Feng Jingchen purchased in the plane system, as long as they were related to words and languages, would be translated into the mandarin he was most familiar with.

Feng Jingchen said familiarly, "I need guidance for beginners."

Optical Brain: "Okay ~ the novice guide starts now."

The operation of this optical computer is not complicated, even more convenient than the smartphone used by Feng Jingchen, but its function is more powerful.

The small box is the host of the optical brain, which can project a virtual holographic light screen that surrounds 360 degrees!

It looks even more sci-fi than the plane system.

Feng Jingchen can directly interact with the things in the holographic light screen, and can also use voice to give commands to the smart assistant.

After half an hour.

Feng Jingchen thoroughly figured out the operation of the optical brain, without any pause, he directly ordered: "008, start programming teaching."

Optical Brain: "Okay."

The holographic light screen swipe and change, countless data flashes quickly, and the tutorial officially begins!

Feng Jingchen had learned some programming knowledge before, although it was not very similar to programming on other technological planes.

But as long as there is basic logic, it is still very easy to understand.

After that, Feng Jingchen didn't do anything.

He just learned all the programming knowledge of the technological plane that can be bought in the system supermarket!

It was because of his long-planned plan.

Feng Jingchen wants to create a dual programming system suitable for metaphysics and science, reality and virtuality!

From Feng Jingchen's point of view, the operation of their entire world is a huge system.

And the various rules and formulas that exist in the objects observed by the eye of reality are a series of codes in the system.

As long as Feng Jingchen can create a programming system that can accommodate these codes, then what he can do in the future... beyond imagination!

Of course, Feng Jingchen didn't aim too high.

His first goal now is to digitize the book of life and death.

As the evil celestial master organization was successively destroyed by Xuanmen, the number of ghosts who came to the underworld on their own initiative these days has increased significantly.

Although the automatic sorting system of good and evil souls was running smoothly, in the end Feng Jingchen had to personally judge each ghost.

When there are more and more new ghosts in the future, this automatic sorting system, which can only do a simple preliminary screening, is bound to be unable to cope.

Only technology, electronics, and intelligence are the main theme of the future development of the underworld!

I do not know how long it has been.

Feng Jingchen suddenly recovered from the research.

At this time, he was holding a seemingly ordinary mobile phone in his hand.

But if you take it apart, you will find that there is no similarity between the inside and the mobile phones sold on the market!

This is Feng Jingchen's first mobile phone that combines science and metaphysics by refining all kinds of garbage in the underworld!

The smooth operation of this mobile phone now also symbolizes that Feng Jingchen's research this time has taken the most critical first step.

only…

Feng Jingchen raised his eyes slightly, and looked into the air with some doubts.

He had a strange feeling just now, he... seems to have forgotten something?

And, it seems to be quite important.

Feng Jingchen glanced around slowly, and finally landed on the date on the phone: August 8th.

He stood up suddenly!

By the way, it's time to start school!

The new little Hades researched his superiors and almost forgot his own job.

Feng Jingchen shook his head lightly, amusedly, but he didn't return to the mortal world immediately.

School does not start until September 9st, and until August 1st is a report day.

There is still some time, let him finish dealing with the affairs of the underworld first.

Feng Jingchen packed up the results of his research during this period of time, and after replacing Xie Zhi with a new battery, he walked towards the gate of hell.

During Feng Jingchen's one-month immersion in research, the ghosts did not give up their efforts.

Now there are 13 ghosts who have learned how to extract "garbage" to build walls.

I don't know who arranged it, but each of the 13 ghosts led 10 men to build walls on both sides of the ghost gate.

When Weng Xiaoshu saw Feng Jingchen, she immediately greeted him courteously: "Yan Wangye, fortunately, the slaves did not disgrace their fate, and completed what you asked."

"That's right." Feng Jingchen looked up at the ghost who was building the wall, "Tell me about it."

"Yes." Weng Xiaoshu smiled even more charmingly, and said in an orderly manner with her clever mouth, "Yan Wangye, you also saw it. Three days ago, we cleaned up the Wangchuan River outside the gate of hell, and now we are starting to clean up the inside of the pass."

"During this time, 13 ghosts have learned how to build walls. Nujia... discussed with Sister Xinyan and assigned them each 10 helpers. They will receive 5 Yunyin Pills every day to help them build walls together."

Feng Jingchen heard Weng Xiaoshu's momentary hesitation in assigning work to Wen Xinyan, looked back at her, and said, "Good job."

Weng Xiaoshu's back was dripping with cold sweat from Feng Jingchen's inexplicable look, and she was also afraid for a while.

Fortunately, she didn't have a momentary obsession.

Otherwise, Lord Yan's impression of her will probably hit rock bottom again!

Weng Xiaoshu took a few deep breaths, barely suppressed the palpitations, and continued to report to Feng Jingchen: "Now these 13 brothers are responsible for the 10-meter city wall. According to their own estimates, it can be completed in about a month."

Of course, these 10 meters were built, not the entire ghost gate.

Feng Jingchen looked up.

Guimenguan is 10 kilometers south to Wangchuan River.

And the north side... is basically blocked by the garbage mountain, and I don't know how far away it is.

If you want to build a city wall, this manpower alone is not enough.

Better yet... improve tool efficiency.

Even - industrialization!

Feng Jingchen had an idea in his mind.

However, he has too many projects to study, and he is a bit out of control.

I don't know how Wu Xinghai's glasses research is doing?

However, it's not good to just catch him alone.Can you try to develop Murong Qiao?

Also, Shi Qiulu's formation is said to be good, but he doesn't seem to like to study it?

Hmm... Maybe he has to find a way to get to know more Celestial Masters.

Feng Jingchen's eyes turned slightly, and he raised his eyes to look at Weng Xiaoshu: "You guys did a good job this time. You and Wen Xinyan's sentence will be reduced by one month each."

The voice fell.

Weng Xiaoshu suddenly felt her body relax.

It's like some kind of heavy shackles have been loosened, making people feel more comfortable to breathe!

Weng Xiaoshu's expression was slightly chilled.

It wasn't until this moment that she really realized that there was such a big gap between herself and other ordinary ghosts.

She... is still a prisoner in chains!

Weng Xiaoshu realized this, and her face paled in an instant, but she still hurriedly blessed her body: "Thank you, Lord Yama, for your kindness."

Feng Jingchen: "Go to work."

"Yes." Weng Xiaoshu's mind is in a mess now, but the figure that has been carved into her bones still allows her to exit the stage very decently.

Feng Jingchen went to inspect the work of other ghosts.

According to Yan Wangyin, the Wangchuan River almost runs through the entire underworld.The section of the river cleared before the gate of hell is just a drop in the bucket compared to the entire river.

So these more than 1000 ghosts work together, which seems to be very efficient, but it is not.

Sure enough, it still needs to be industrialized.

Feng Jingchen walked forward while thinking.

Suddenly, he discovered that the things the ghosts were holding seemed... a little unexpected?

Feng Jingchen took a few steps quickly with his long legs and could see more clearly.

Sure enough, they are hoes, rakes, shovels, and various containers and other tools!

Where did these things come from?

Feng Jingchen just wanted to ask.

However, when the ghosts saw him, their movements became involuntarily stiff, and some ghosts retreated frequently in fear.

Those ghosts who have been burned by the red lotus karmic fire have trembling calves, wishing they could faint on the spot!

Feng Jingchen: "..."

Fortunately, not all ghosts are so timid.

Feng Jingchen turned around and walked towards accountant Li Xingguo,

Li Xingguo had been in contact with Feng Jingchen a lot these days, and he already knew that their little Yama was not as fierce as he appeared on the surface.

Seeing Feng Jingchen approaching, he greeted him very warmly: "Lord Yan, why are you free today? You still have a lot of Yunyin Pills you gave last time, and I guess I can give them another month."

Feng Jingchen nodded lightly, looked at the tools in everyone's hands: "Where did those come from?"

Li Xingguo smiled and said: "Oh, that one, it was made by Blacksmith Fang for the big guy."

He looked outside the gate of hell, a thin middle-aged man.

The man was fiddling with an earthen kiln, seemingly repairing something.

Feng Jingchen also noticed him before.

But now every team building the city wall has several kilns for refining materials, so that man is not very eye-catching.

Li Xingguo introduced: "Blacksmith Fang used to be a blacksmith, but after reading the book you gave me, Lord Yan, he learned a new smelting method, and started making tools for everyone."

"Everyone praises his craftsmanship! He said that the things he made are easier to use than those chainsaws and excavators that he used before, and they are sharp and labor-saving!"

"Oh?" Feng Jingchen was a little surprised.

But I also understand what's going on.

That book was written by a master alchemist. In order to teach everyone to build a wall from scratch, it is natural to start with tools.

But the smelting method he taught is not an ordinary technique, but an introductory technique of alchemy!

Those tools can be regarded as half alchemy equipment after they are manufactured, so can they be used well?

On the contrary, the efficiency of the tools produced can be compared to that of machinery, which Feng Jingchen did not expect.

Looking at Tiejiang Fang's back, Feng Jingchen turned his eyes slightly, and soon had a new idea in his mind.

He said to Li Xingguo: "Uncle Li, you can ask Blacksmith Fang later to see if he is willing to become a full-time mechanical manufacturing engineer in our underworld."

"If you want. Whenever he has mastered all the smelting methods in that book, he can come to me at any time."

Feng Jingchen didn't ask in person.

He knew that these ghosts were afraid of him.

People make decisions when they are afraid, and they often regret it later.

Feng Jingchen didn't want to harvest an employee who had no subjective initiative at all.

Li Xingguo didn't know if he understood Feng Jingchen's meaning, but he nodded solemnly: "Don't worry, Lord Yan, I will definitely tell him this word for word."

Feng Jingchen gave Li Xingguo another batch of Yunyin Pills: "I may not have time to come back recently. If there is not enough, let's record it first."

These days, the Yunyin pills earned by the ghosts are actually enough for them to eat for more than half a year, and they are not in a hurry to ask for wages in kind.

"Okay." Li Xingguo put all these Yunyin pills into the iron box that Fang Blacksmith made for him, and kept them carefully.

After Feng Jingchen explained everything, Yan Wangyin hadn't come back yet.

So he didn't wait, and went back directly to Yangjian.

Feng Jingchen had just landed on the ground.

Suddenly a warm wind hit!

Feng Jingchen subconsciously wanted to call out the big black umbrella, but he was hugged all of a sudden.

"Ayu!" Murong Qiao hugged Feng Jingchen tightly, his voice was a little anxious, "Why haven't you come back for so long? I thought something happened to you!"

Feng Jingchen's body stiffened slightly.

Murong Qiao's embrace was very soft and warm, giving him the illusion of being completely enveloped by the other's breath.

Feng Jingchen was a little unaccustomed to such an intimate hug, and subconsciously raised his hand to grab Murong Qiao's arm.

But after thinking about it, he didn't push Murong Qiao away.

Feng Jingchen looked up at Murong Qiao.

In those bright peach blossom eyes that came from both directions, there was deep worry at this moment.

Feng Jingchen's long eyelashes trembled slightly, and for the first time he felt a bit guilty: "I did a task in the underworld, which is relatively complicated, so I haven't come back."

"Really?" Murong Qiao looked at Feng Jingchen suspiciously.

But he doesn't care about Ayu.

He just hugged her tightly, with a serious and cute expression: "Forget it this time. If there is a next time, be sure to tell me in advance!"

Seeing his appearance, Feng Jingchen consciously showed a faint smile: "Okay."

Only then did Murong Qiao let go of his hand in satisfaction: "Fortunately, Ayu, you came back in time, otherwise you won't be able to catch up with the start of school."

Feng Jingchen: "It's also for this reason that I interrupted the mission and came back."

at this time.

Murong Xiaoxiao's anxious voice suddenly came from outside the door: "Murong Qiao, who are you talking to? Is my brother Chen back?!"

Before he could finish speaking, he suddenly pushed open the door.

Seeing Feng Jingchen, Murong Xiaoxiao was so happy that she almost cried: "Brother Chen, my brother Chen, you are back! If you come back two days late, the class teacher and principal may be going to the rooftop."

Murong Xiaoxiao grabbed Feng Jingchen: "Brother Chen, hurry up, I'll take you to get the admission notice."

Feng Jingchen was dragged out, wondering: "What's going on?"

Murong Xiaoxiao: "The person who delivered the admission letter couldn't find you, so they sent you to our school! But the teacher in charge and the principal couldn't get through to your mobile phone. They thought something happened to you. They almost cried to death."

Murong Qiao crossed his arms and followed leisurely: "Isn't it just a notice, what is there to worry about? I think Ayu might as well come to the Department of Religion at Huada University. As you are, you can definitely enroll directly. ~"

He winked playfully at Feng Jingchen: "Ayu, do you want to come? Huada~"

Compared with these questions with fixed answers, he still prefers to explore unknown answers.

"..." Murong Xiaoxiao, a low school student, stopped abruptly.

He looked back at his brother Chen with a speechless face.

Murong Qiao also chuckled softly, and slapped Murong Xiaoxiao's grasping Feng Jingchen's hand away: "Okay. I'll take Ayu back. You go back and pack your luggage properly, and we'll be on our way when we come back."

Murong Xiaoxiao naturally refused to accept it.

But Murong Qiao's eyes swept away lightly, and she was instantly terrified.

Can't be bothered, can't be bothered.

He snorted softly: "What's good, you go to the capital to suffer from the cold. I'm going to
