I use technology to revitalize the underworld

Feng Jingchen already had several preset plans for finding the evil mirror platform.

The first one is like summoning the book of life and death at the beginning - rely on God!

He paced back to the small square behind the ghost gate, closed his eyes with bated breath, and carefully recalled the state of summoning life and death.

Seeing his appearance, Yan Wangyin immediately guessed what Chen Chen was going to do, and couldn't help holding his breath nervously, staring at Feng Jingchen without blinking.

After a tense silence.

Suddenly, a gust of wind blew by.

Yan Wangyin's heart immediately rose to his throat!

They are even mentally prepared to shake the earth and shake the mountains!

And yet... nothing happened.

Yan Wangyin: "?"

It looked at Feng Jingchen's still tall and straight figure, although his mind was full of doubts, he still suppressed all his thoughts temporarily.

Chenchen should not fail... right!

however.

1 minute, 2 minutes... a full 5 minutes passed!

Feng Jingchen remained silent!

This is completely different from the situation that caused a sensation in the entire underworld!

Yan Wangyin was dumbfounded.

At this moment, Feng Jingchen slowly opened his eyes and couldn't help but sigh with some regret.

The golden net and that mysterious existence didn't respond to him anymore.Even faintly, Feng Jingchen felt a bit of resistance.

It's like... getting swept away as an adult by impatient parents.

A helpless chuckle flashed in Feng Jingchen's eyes.

It seems that this shortcut really can't be taken anymore.

After getting the Eye of Reality, Feng Jingchen had a vague premonition of this.Just wanted to check again today.

Sure enough, it is not so easy to rebuild the underworld.

Feng Jingchen looked up at Yan Wangyin who was stunned in the distance: "What's wrong with you?"

"It's nothing!" Yan Wangyin came back to his senses, and quickly floated over to comfort him, "Chen Chen, don't be sad, it must be because the evil mirror is too heavy! Heaven can't lift it up."

It's not that the way of heaven ignores Chen Chen.Their family Chenchen must be very good! !

Feng Jingchen didn't know what Yan Wangyin had imagined, he pinched the little seal lightly: "I'm not sad."

This first method won't work, and he still has alternatives.

Feng Jingchen didn't delay, and quickly walked to the side of the metal mountain that the ghosts sorted out.

The evil mirror table is a bronze mirror, if its fragments are picked up, they should be distributed here.

No nonsense, Feng Jingchen picked up an unknown metal piece the size of a palm, and opened the eye of truth with his right eye.

Soon, Feng Jingchen and Yan Wangyin shook their heads together: "It's not the evil mirror."

So Feng Jingchen put this fragment into the warehouse of the plane, and continued to pick up the next one.

In this way, Feng Jingchen and Yan Wangyin recognized each other one by one.

This work is very boring and tedious.

An hour, two hours... until five hours later, the southeast corner of the metal mountain has been picked up.

The damn mirror is still missing!

Yan Wangyin, a child with low concentration, quickly became sluggish and began to lose his mind frequently.

It was Feng Jingchen.

From the beginning to the end, not only did his movements and attitude not change at all, but he became more and more immersed in it!

Because every piece of metal here has its own unique brand of rules.

Every time Feng Jingchen identified a piece of metal, a rule fragment was naturally generated in his mind.

Gradually, some of the regular lines connected in his mind, and the incomplete imprint of the rules gradually became complete.

Until Feng Jingchen accumulated more and more rules in his mind.

Finally, quantitative change leads to qualitative change!

Before he was in the golden net, he observed many formulas that could not be translated.

Now that the number of these regular puzzles has reached a certain level, they suddenly start to be unraveled one by one like a chain of nine locks!

Integration, statistics, variables... and other formulas are on the scene.

What followed was that in Feng Jingchen's research plan, the originally vacant positions were filled with corresponding formulas and values ​​one after another.

Then, more inspiration came!

The defects that were not found in the previous plan were filled in time; the functions that could not be achieved before have also begun to be improved bit by bit...

The more active Feng Jingchen's brain was, the faster he picked up metal pieces.

In the end, even Yan Wangyin hadn't confirmed whether it was the evil mirror platform, and he had already thrown the pieces into the warehouse of the plane.

"Chenchen, you are too fast..." Yan Wangyin hadn't finished speaking.

When it turned around to look at Feng Jingchen, its whole body went numb.

Oh, another epiphany.

That's fine.

Yan Wangyin doesn't even bother to complain now.

Seeing that Chenchen was fine by himself, he simply wandered around to protect the dharma by the way.

Two days later.

A whole mountain of metal was picked up by Feng Jingchen.

Feng Jingchen suddenly raised his eyes, and a sharp light shot out from under the lens!

He figured it out!

This epiphany swept away all of Feng Jingchen's previous confusion and bottlenecks.

The feasibility of his plan exists, and even the success rate is not low!

Now, Feng Jingchen has collected enough formulas, the only thing missing is experiments.

Lots of experiments!

After clarifying this point, Feng Jingchen's eyes sparkled with excitement.

If that plan can really be realized, he can't wait to see what the future hell and the world will look like.

Feng Jingchen thought about some details carefully, and subconsciously took out a bottle of Bigu Pill.

But before he opened the bottle cap, he suddenly reacted.

After using the Eye of Reality for a long time this time, he was not so hungry that his hands and feet were soft?

With a thought in his mind, Feng Jingchen looked intently at Dantian.

really.

Originally, nearly one-tenth of the mana had been stored, but now it has almost bottomed out!

Feng Jingchen's thin lips hooked slightly.

This is also a good thing.

As long as he has enough mana, he won't starve himself to death because of the long time of epiphany.

However, according to the frequency of his epiphany, maybe he has to find a time to upgrade and optimize the automatic cultivation program.

Otherwise, he might not even try to fill his dantian in his life.

If Yan Wangyin knew what Feng Jingchen was worried about, he might start roaring again.

Other geniuses don't necessarily have an epiphany once in thousands of years, and someone is as normal as eating and drinking.

Really more popular than dead people!

Fortunately, the little Hades seal is now ignorant.

"Chenchen~" it flew over cheerfully, and asked curiously, "What did you suddenly realize?"

Feng Jingchen looked up at it, and only mentioned the latest goal in the plan: "A new function of the book of life and death."

"Ah?" Yan Wangyin was confused.

What new features can the book of life and death have?

Feng Jingchen smiled mysteriously and said nothing: "Let's find the Nie Jingtai first."

If he can find the Niejing Platform, it will also be a great help to his research.

"Oh~" Yan Wangyin was still very obedient.Fluttering and Huhu, he flew towards the next metal mountain.

There are four metal mountains sorted out by the ghosts.

Now that Feng Jingchen has cleared one, he only hopes that there will be fragments of the evil mirror platform in the remaining three.

Otherwise, they might have to turn the whole underworld upside down.

As soon as Feng Jingchen thought of this, suddenly, he and Yan Wangyin let out light surprises together.

Yan Wangyin excitedly rushed towards the second metal mountain: "Chenchen, I sense the breath of Nie Jingtai, it's in that mountain!"

After finishing speaking, Yan Wangyin couldn't help muttering: "But, I've been here many times, and I haven't sensed it before? It's so strange."

I don't know if it's the treasure's own obscurity, but Yan Wangyin has wandered around for so long after returning to the underworld, and has never encountered a familiar aura.

Otherwise, Feng Jingchen didn't need to work so hard to pick up trash piece by piece.

Hearing this, Feng Jingchen had a vague guess in his heart.

Because he was surprised just now, not because he sensed the Nie Jingtai.Rather... There is a change in the warehouse of the plane!

With a thought in Feng Jingchen's mind, a large warehouse with two meters in length, width and height silently appeared in midair.

The warehouse was neatly tidied up.

Even though Feng Jingchen was having an epiphany just now, those metal fragments were neatly classified and arranged according to the different shapes and rules.

So now Feng Jingchen can see a blue bead in the depths of the warehouse, emitting a faint light bit by bit.

This is... the core of the ghost mother formation that Feng Jingchen snatched from Xie Tianshi's station!

Yan Wangyin looked at the bead, and jumped up excitedly again: "Ah! Let me tell you why it looks so familiar. Chen Chen, this is Xiezhi! This is Xiezhi's remnant soul!"

"Xiezhi?" A legend related to it immediately appeared in Feng Jingchen's mind, "A legendary beast that can tell right from wrong, good from evil, loyal and treacherous?"

Yan Wangyin: "Yes! It and Nie Jingtai are good friends, they must have sensed each other, Chen Chen, take it out and have a look."

With a thought in Feng Jingchen's mind, the blue beads in the depths of the warehouse immediately flew out and fell into his palm.

Without the shackles of the plane warehouse, the light emitted by the beads is brighter and faster.

And Feng Jingchen also clearly sensed the metal mountain in front, and a very active aura suddenly appeared!

"Ah, I found it!" Excitedly, Yan Wangyin plunged headlong into the metal mountain!

The metal fragments on the mountain were knocked down by Yan Wangyin.

And within a few seconds, a bigger shock came from inside the mountain!

Feng Jingchen immediately took several steps back.

next moment.

The entire metal mountain seemed to be a domino that was tossed, and suddenly began to collapse from the inside!

The nearby ghosts were all taken aback.

Weng Xiaoshu hurried over: "Lord Yan, what's the matter?"

"It's okay, I'm digging something." Feng Jingchen raised his hand to prevent her from approaching, "Don't panic, go talk to Uncle Li, and hire someone to clean it up later."

When Weng Xiaoshu heard this, the expression on her face froze.

Lord Yan wants to hand things over to that old accountant?Then her status is going to be lost? !

A sense of crisis suddenly rose in Weng Xiaoshu's heart.

She reluctantly answered "Yes", but the expression on her face changed rapidly.

No, she has to find a way to regain her position in Lord Yan's heart!

Weng Xiaoshu's expression froze, she twisted her slender waist, and turned to leave.

And she just walked away.

In the scattered pile of metal, suddenly there is a gold seal that soars into the sky!

Feng Jingchen looked up.

I saw a piece of brass metal with very irregular edges stuck under Yan Wangyin's body.

It is a fragment of the evil mirror!

"Chenchen, I found it!" Yan Wangyin slammed into Feng Jingchen's arms.

It handed the fragment to Feng Jingchen like a treasure: "This is the most central fragment of the Niejing Platform. As long as we have it, we can easily find other fragments!"

Yan Wangyin proudly asked for credit: "Look at me, I'm not very good~"

"Excellent." Feng Jingchen curiously took the fragments of the Nie Jingtai.

This fragment is about the size of a palm.

One side of the light can be used as a guide, and it is even more delicate than a glass mirror!

On the other side, there are dense and complicated fine lines.It looks not only luxurious, but also mysterious.

Murong Qiao observed with the eyes of reality, and could see some fragmentary regular lines in the fragments, somewhat similar to those in the Book of Life and Death.

This should be their functional module for judging merits and demerits!

It's just that this fragment of the evil mirror table is too small, and Feng Jingchen can't extract useful rule information from it.

Just as Feng Jingchen was looking at the fragments of the evil mirror table, the "blue bead" in his hand suddenly gradually lost its light.

When all the light was gathered inside the bead, a small black animal was transformed into a reality.

It squatted in the bead, and yelled weakly in the direction of the evil mirror.

Its cry is very small, it sounds like a mosquito.

Feng Jingchen turned his head when he heard the sound, and looked at this little beast that was only the size of a thumb in novelty.

Under the eyes of reality, Xiezhi has also become a small ball of light like Yan Wangyin.

It's just that its radiance is much dimmer than that of Yama's Seal, like a candle in the wind, which will go out at any time.

Feng Jingchen frowned slightly: "Xiaoyin, what's the matter with this Xiezhi's remnant soul? What is it talking about?"

Yan Wangyin floated in front of Xiao Zhuzi: "It's talking to Nie Jingtai~ tsk tsk tsk, poor little thing. Nie Jingtai hasn't recovered yet, so I can't hear you~"

"?" Xiezhi angrily yelled at Yan Wangyin!

But it didn't bark a few times, and hung its head limply as if exhausted.

Seeing its frail appearance, Yan Wangyin felt that bullying children was meaningless.

So he flew back to Feng Jingchen's shoulder, and introduced: "When the heaven fell, Xiezhi also went to the world to save the world, and never came back after that."

"Looking at its current state, it must have encountered some accident, and it was seriously injured to the point where only this remnant soul is left."

Feng Jingchen raised his eyes suddenly: "It participated in the last battle?"

"Yes." Yan Wangyin recalled, "Actually, Xiezhi often stays in the sun. I heard from Nie Jingtai that after the collapse of the heaven, it was the first batch of divine beasts to save the world."

When Feng Jingchen heard this, his eyes sparkled with excitement: "In other words, it may know more about the truth and process of the collapse of the Heavenly Court."

Yan Wangyin: "Yes!"

Feng Jingchen and Yan Wangyin Qiqi turned their gazes to that weak, pitiful, and helpless little black beast.

Xiezhi tilted his head in doubt: "Aww?"

Feng Jingchen gently touched the little bead: "Can you speak human language?"

"Woo..." Xiezhi lowered his head weakly.

Yan Wangyin: "Chenchen, it's too small. I heard that the beasts have to be adults before they can speak."

Cough, although Xiezhi was an adult before.But now this remnant soul has turned back into a cub, then it is a cub!

Feng Jingchen also nodded slightly: "It looks very weak, is there any way to help it?"

Yan Wangyin: "Just send it to a place with sufficient energy~ It will absorb energy and recover by itself."

When Feng Jingchen heard the words, an excellent place immediately appeared in his mind.

He looked down at the weak little beast: "Then how long will it take to grow into an adult?"

Yan Wangyin: "Ah, it depends on how much energy it absorbs. It can be as short as ten years, or as long as tens of thousands of years."

It's easy for Yan Wangyin to say this, because it has experienced countless years.

However, Feng Jingchen frowned slightly.

As short as ten years?

For his life span of only 19 years, that was too long.

It seems that they have to think of a way to improve Xiezhi's recovery efficiency in the future.

Feng Jingchen narrowed his eyes slightly, and soon had a thought.

But he hasn't forgotten their main task now.

Feng Jingchen looked at the fragment of the evil mirror in his hand: "What about it? It seems that it can't be used now?"

"This..." Yan Wangyin circled around the fragments of the evil mirror, and finally came to a conclusion, "It's broken."

Feng Jingchen: "...?"

Xie Zhi: "Aww!!" You are broken!

Yan Wangyin is innocent: "It can't be used anymore. It is indeed broken. It is estimated that all the fragments must be recovered to restore its function."

When Feng Jingchen heard this, a few strands of golden light flashed in his right eye, and he probably understood what was going on in his heart.

Because the evil mirror platform is broken into an unknown number of pieces, the rules of each piece are incomplete, and cannot form a complete "formula", or a circuit.

This is of course unusable.

So, now either keep looking for the remaining pieces, or... find a way to fix it!

Feng Jingchen's eyes turned lightly: "Xiao Yin, take this fragment and go find the remaining fragments, and I will settle Xie Zhi."

"Okay~" Yan Wangyin was very excited when he saw that the underworld was recovering bit by bit, and the shards flew away all at once.

Xiezhi sensed that his good friend's breath was away, and immediately yelled uneasily.

But no matter how anxious it was, it was always lying in the bead, and it didn't have the strength to stand up at all.

Feng Jingchen also noticed that in just ten seconds, the light on Xie Zhi's body became much dimmer, as if it would go out at any moment!

Feng Jingchen's eyes were fixed, and he walked quickly to the gate of hell.

At the same time, he touched the beads and comforted him: "We are going to look for the other fragments of the Nie Jingtai now. You can keep it at ease. After you recover, maybe it will come back."

Hearing this, Xiezhi tilted her head.

I don't know if it understood or not, but it finally calmed down.Crouching in the beads, with a dull head, looking very pitiful.

Soon, Feng Jingchen came near the energy compression device.

As soon as he approached, he suddenly sensed an unusually strong Yin Qi!

In the energy storage box of the compression device, a small handful of black soil was emitting a mellow light.

Seen with the eyes of reality, this cloud of cloudy soil is as bright as a light bulb!

This energy concentration has definitely been upgraded!

Feng Jingchen was overjoyed, took out the Yintu from the storage box, and opened the plane system.

With a thought in his mind, a sentence popped up on the light screen——

[It is detected that you hold 5g of secondary Yin-type soil, and each gram can be sold for 10000 transaction points.Is it for sale? 】

It really is a second-class Yin soil, and the price has increased by [-] times? !

Feng Jingchen turned his eyes slightly, canceled the sale, and only put this small handful of Yin soil into the warehouse of the plane.

Then, he spread another layer of soft first-grade shady soil into the energy storage box before putting Xiezhi in it.

As soon as Xiezhi came in, he felt a much stronger Yin Qi than the outside world.

It trembled all over, clumsily turned over in the bead, and yelled "嗤嗤~" very comfortably.

Seeing that it liked it, Feng Jingchen said, "Then you stay here well."

Xiezhi didn't care about any good friends this time, and said happily: "Aww!" Okay~

Feng Jingchen thought for a while, and then took some relatively flat pieces of metal from the warehouse of the plane, and built a table for the alchemy device.

And put up a notice board next to it, strictly prohibiting ghosts from moving around.

After doing all this, Feng Jingchen reopened the plane system.

When he opened the system supermarket just now, he saw someone sending him a message in the friend channel.

Clicking on it, it turned out that Lord Dalk replied to his last message!

[Lord Dalke]: How big do you need it?I can make a maximum of 100 cubic meters, and can absorb 110 energy per second.

Feng Jingchen thought for a while, but did not blindly pursue the greatest.

[Successor of Socialism]: How much energy does a device of this specification consume?

Coincidentally, Lord Dalk was also online at this time, and his reply was quick.

[Lord Dalke]: Long time no see.

[Lord Dalke]: A level-three energy battery can last for about a week.A large installation inevitably wastes energy, and its conversion rate will be 10% lower than the one I sent you.

Energy batteries are a uniform product in the system supermarket, and there will be basically no price fluctuations.

The small compression device that Lord Dalk sent uses a first-class energy battery, and the unit price in the supermarket is [-] credits.

Now half a month has passed, and the battery is almost exhausted.

And a three-level energy battery needs 10 points...

Based on this calculation, if he uses this large energy compression device to create a second-level shade soil, the profit margin will be around 40%.

It can be regarded as a huge profit.

However, Feng Jingchen turned his eyes slightly, and tapped the light screen a few times with his fingertips.

[Successor of Socialism]: [Secondary shade soil*5g], how many points can this be sold for?

The square brackets in Yintu represent products that can be clicked to view details.

As long as things are put into the plane warehouse, the system can automatically form such a link.

This also shows people: you own this product!

Sure enough, Lord Dalk's reply was quick and exciting.

[Lord Dalke]: Me! !Can I pay 10 points to buy it?Of course, if you can find more second-level shady soil in the future, I can use the largest energy compression device to exchange these five grams of shady soil with you.

[Lord Dark] The market price of that alchemy device is 500 million points.As long as you promise to sell me 2 grams of secondary yin soil at a price of 250 points per gram within ten years, that is, yin soil worth 500 million points in total, then it will be yours!

[Lord Dalke]: My good friend, I hope you can think about it clearly.Currently on the forum, there are no more than five people who can make such a large alchemy device.

[Lord Dalke]: If you agree to this deal, you can also gain the friendship of a master alchemist.

[Lord Dalke]: Of course, if you have other needs, feel free to tell me.Believe me, I am 200% sincere about this deal.

Looking at this series of words, Feng Jingchen really felt Lord Dark's desire for the second-level Yin soil.

Moreover, in Feng Jingchen's opinion, the conditions he gave were indeed very generous.

but…

Feng Jingchen narrowed his eyes slightly, raised his hand and tapped the light screen a few times, and sent his reply.

[Successor of Socialism]: How can you be sure that after this transaction, I will abide by the ten-year agreement?
