Chu Fei said hello to Wu Yong and Zhou Pengyue, and flew directly to Black Iron City with Feathered Serpent.

In fact, everyone had complicated thoughts about Black Iron City and Hong Qingxin, the city lord behind Black Iron City.

At this chaotic moment, can Black Iron City be kept?

This question has been lingering in Chu Fei's mind, and it is also a question that the 1.5 million people in Dawn City are discussing now.

Seeing Black Iron City again at this time, I only saw that Black Iron City had been initially repaired. The collapsed walls had been repaired, and the crumbling walls had been reinforced.

Even the outward-turning guardrails were being installed on the top of the city, so that the top of the city could be turned outward a little to increase the difficulty of climbing.

A large number of people, even controlled beasts, were going in and out of the city, a busy scene.

Black Iron City was able to complete the repair in less than two months, thanks to the participation of a large number of beasts in the construction.

Someone met Chu Fei at the city gate, and an old and mottled vehicle was used as a welcoming car.

When we got to the city, we saw that the houses were still very dilapidated, but the various production plants had been strengthened and repaired, and the roar of machines echoed in the streets.

It can be seen that Black Iron City has done everything possible to repair the city walls and resume industrial production. As for people's livelihood, they were all put behind.

Fortunately, Black Iron City is not short of food now.

Chu Fei saw a transport truck passing by. The truck bed was welded with steel bars, and a large number of half-meter-long "silkworms" were placed in it, entering a food processing factory.

These "silkworms" were carefully taken care of, and there were three people in the truck bed who were responsible for them.

In the food processing factory, "compressed biscuits" were constantly output.

Chu Fei couldn't help asking what this was.

Speaking of which, because of the special management of Black Iron City, intelligence work is completely infiltrated.

The person who responded said: "That is bread silkworms. They can devour plant fibers and convert them into starch output. Although the taste is not very good, it is indeed edible."

Chu Fei observed carefully again and found that it was true.

Those "bread silkworms" were eating broken, wet sawdust and leaves in big mouthfuls, and behind them, "silkworm excrement" of three or four centimeters in size was constantly rolling out and piling up.

Silkworm excrement can be used as medicine, so of course it can be eaten!

Then this mutant bread silkworm has similar functions, which is no big deal.

As for the taste, that's secondary. This is the end of the world, and it's good to have a bite to eat. At least it's not the cockroach biscuits in the movie.

Along the way, Chu Fei saw a lot of factories. Chu Fei vaguely understood, is this Hong Qingxin showing off his muscles to himself?

Soon he came to the City Lord's Mansion, and the feathered serpent stayed outside, "fighting" with the three-headed python in the yard.

Chu Fei entered the yard and saw Hong Qingxin again.

Compared with the last time, Hong Qingxin became more and more "human", his face was no longer so hideous, and he also had a kind of calmness and majesty of a superior.

Meeting again after a month, the changes in Hong Qingxin were still very obvious.

But Chu Fei's change was even greater. Hong Qingxin looked at Chu Fei, and a hint of fear flashed in his eyes.

Hong Qingxin felt a hint of danger from Chu Fei.

This dangerous aura made Hong Qingxin feel like a thorn in his back.

However, Hong Qingxin's eyes only flickered slightly, and he let Chu Fei sit down with a proud attitude.

Chu Fei chuckled, "Hong Qingxin, did you receive the distress message from Hongcheng?"

Hong Qingxin narrowed his eyes slightly, and Chu Fei's attitude made him very unhappy. But after thinking about it, he finally nodded coldly and said in a hoarse voice: "I received it, but I don't think Hongcheng is worth saving now."

Obviously, Hong Qingxin is not a fool, and knows the current situation of Hongcheng.

Chu Fei did not beat around the bush and said directly: "But I think Hongcheng can be saved and must be saved.

Hongcheng now has a population of 1.8 million. If it is not saved, the scale of the zombie tide will expand by 1.8 million.

The most important thing is that the zombie queen and the zombie high-level will absorb the life energy of 1.8 million people.

Can you imagine what the consequences will be?"

Hong Qingxin's face suddenly stiffened. After a long time, he took a deep breath, nodded slowly, and spoke again, but his voice was less cold:

"You said, how should we save it? I can't think of a rescue method for the time being. All rescue methods can only scratch the surface.

More than 7 million zombies!

More than 7 million!"

Chu Fei said calmly: "Whether the rescue can be successful is one thing, and whether to save or not is another.

We must save, and we must show a sufficiently firm attitude.

Only in this way can we inspire the desire to save ourselves in Hongcheng and have hope.

To be precise, our support is just to give Hongcheng confidence."

Hong Qingxin nodded slowly, thinking about it. "So that's how it is. We can organize a team now. I wonder how long it will take for your 'Dawn City'?"

Hearing Hong Qingxin's emphasis on 'Dawn City', Chu Fei just smiled, "It also takes a day to prepare. It's the motorcycle team from last time."

"Linyuan Team, I know." Hong Qingxin smiled, and I don't know how many thoughts flashed through his narrowed eyes.

Although the history of this Linyuan Team is only one month, the results of the battle are really brilliant.

Chu Fei doesn't care how much Hong Qingxin has, in fact, Chu Fei has a lot of thoughts about Hong Qingxin.

The last time Chu Fei retreated from Hongcheng, there was an important reason, which was to prevent Black Iron City from stabbing him in the back.

In fact, Chu Fei was also thinking about how to kill Hong Qingxin. Such a life form combined with a brain beast is really too dangerous.

Today's Hong Qingxin is obviously growing and transforming rapidly. Once this guy completes his transformation, I'm afraid it will be another disaster, no worse than the tide of living corpses.

But for the time being, the tide of zombies is more dangerous and imminent.

Hong Qingxin was even more anxious than Chu Fei. The tide of living corpses was really going to come, and Black Iron City would bear the brunt. Moreover, Hong Qingxin only had such a base. If Black Iron City was lost, Hong Qingxin would have no place to stand.

Chu Fei and other 'people' can move inland, but he, Hong Qingxin, is not a human!

Believe it or not, after entering the interior, he was captured by a research institute and sectioned for study.

But it doesn't mean that there is no way out. The worst is to run away with all the attachments.

The people and animals in Black Iron City are all controlled by Hong Qingxin. If he really wants to run away, no one can object. The worst case scenario is to go to the wilderness and build another city, but it's not that easy to build a new city in the apocalypse.

Unless absolutely necessary, Hong Qingxin will not give up his current foundation.

With these considerations in mind, Hong Qingxin began to negotiate terms with Chu Fei.

As a result... Chu Fei was not as open as the lion, and actually talked about cooperation instead of talking about conditions.

The approximate conditions for cooperation given by Chu Fei are:

1. Black Iron City will send out some flying beasts to be responsible for on-site arms transportation, mainly to transport supplies to Chu Fei’s Linyuan team.

Linyuan Team is a motorcycle team, characterized by: rapid maneuverability, strong environmental adaptability, low resource consumption, but also carries few resources;

Because of these characteristics, the locomotive team has special requirements for logistical supplies: it must be efficient and fast, and the amount of supply can be small each time, but the frequency of supply is very high, especially when the locomotives go to many places that ordinary vehicles cannot pass at all.

Because of this, when fighting in Hongcheng, every battle was calculated in minutes. In the end, the battle lasted for five or six days, and the total fighting time was just over nine hours.

However, there are also flying zombies when it comes to living corpses, and ordinary aircraft cannot safely support them at all.

The flying zombies are at level 8.0, and there are at least twenty or thirty of them every time.

Therefore, in this battle, Chu Fei will transport the resources needed by the motorcycle team from Feihu City to Black Iron City; here in Black Iron City, flying alien beasts will be dispatched to transport the materials until designated.

It is initially estimated that only 30 ordinary mutant falcons are needed to meet the team's supply needs; but how to communicate is a big problem.

2. Black Iron City will send out a group of small flying birds and beasts as "satellites" to monitor the scene at all times.

3. Black Iron City will now begin to implement the strategy of fortifying the wall and clearing the wilderness in the north, setting up firepower points at key locations and laying mines on important passages.

In fact, the strategy of strengthening the wall and clearing the field has been carried out for a long time, but setting up fire points, laying ambush mines, etc. needs to be carried out as soon as possible.

4. Prepare temporary shelter, food, drinking water, etc. for treating the wounded, transferring personnel, and even rescuing those who have escaped from Hongcheng, etc.

Finally, the original condition of the negotiation in Hongcheng was that Chu Fei had to enter the dimensional space of Black Iron City once, and now Chu Fei raised this condition again.

Hong Qingxin heard that Chu Fei's conditions were absolutely fine, and could even be said to be what Black Iron City had to do.

Rather than saying it is a condition, it is better to say that it is the responsibility of Black Iron City in the cooperation between the two parties.

This last condition has been negotiated long ago.

Hong Qingxin nodded, "It will take about five to seven days to prepare these.

When are you going to enter the dimensional space? "

"Now, I'm afraid I won't be able to find time in the future."

"No problem." Hong Qingxin said simply, but then added: "But I also have some conditions for this cooperation."

"Please say."

Hong Qingxin's first question made Chu Fei frown: "The first is the resurrection disc. The resurrection disc you brought out from the dimensional space was later divided into three parts of the code. The disc was kept in Feihu City and should be in Wu Yong's hands now.

It is foreseeable that there will be unimaginable deaths in this war, and the resurrection disc will be useful. What do you think? "

Chu Fei frowned slightly, Hong Qingxin really gave himself a problem.

But after thinking about it, Chu Fei still said, "The resurrection disc is indeed in the hands of my master now, but it was originally stored in the city lord's mansion and was damaged by the old city lord. It should be destructive research.

As for the password, I'm afraid the old city lord's password has been lost. "

While talking, Chu Fei opened his bracelet and pulled out a picture to show to Hong Qingxin. If everyone hadn't started to cooperate, Chu Fei wouldn't be so self-conscious.

After seeing the breakthrough, Hong Qingxin frowned. He also wanted to take the opportunity to do some trick, but it seems useless now.

Resurrection discs, a powerful "ancient high-tech treasure", once damaged, cannot be repaired now.

This thing is useless!

Although the three-headed giant python also has the ability to recover, it is ultimately inferior to the resurrection CD.

Chu Fei said leisurely, "This is just a condition. I will have someone deliver it later."

Chu Fei was very generous with useless scraps.

Hong Qingxin opened his mouth, but finally skipped this and started to mention other conditions: material support, human support, pharmaceutical support, food support, etc.

Perhaps because of Chu Fei's "sincere example", or perhaps because Hong Qingxin considered his own situation, etc., for whatever reason, Hong Qingxin was not as open as a lion.

Because both parties were "sincere enough", the negotiation was concluded quickly.

As for the statistics and distribution of spoils, the points system was used. The points system has been implemented in Feihu City and its surroundings for a long time. It has a mature model and is fair enough.

Chu Fei immediately sent the negotiation message back to Feihu City, and someone here would naturally pass it on to Zhou Pengyue. What happened next had nothing to do with Chu Fei.

Chu Fei had already entered the dimensional space of Black Iron City. This was Chu Fei's second and last entry.

Coming to the dimensional space again, Chu Fei first took a deep breath, feeling the rich and active life energy in the air, and his thoughts drifted away a little:

Is this what the so-called aura in the mythical world is talking about?

Then he looked up at the nine-story peak in front of him and the nine-story trial pyramid towering into the sky, and exclaimed again. After exclaiming for a while, Chu Fei finally uttered two words: Oh fuck!

Although it was the second time to enter, the shock was even greater than the first time.

Such a huge dimensional space is open for a maximum of seven days each time, and a large area inside has not been explored.

This time, Chu Fei's goal is to explore as much as possible. The minimum goal is to collect a lot of information; the maximum goal is to find the inheritance like the underground space of Feihu City.

While thinking, Chu Fei has spread his wings and started to fly at full speed.

There are strange mechanisms in the dimensional space here. The sky is full of turbulence, which interferes with flight.

Now Chu Fei can face these turbulences calmly. He only sees that Chu Fei's flight route is winding, but extremely fast. He flies a thousand meters away in the blink of an eye and begins to search the earth.

With the experience of last time, plus the information given by Song Lihua last time, Chu Fei quickly found the door of the trial pyramid in front of him.

There are two ways to climb this trial pyramid, one is to fly up, and the other is to climb up along the mountain road.

In fact, climbing up is the most formal and most suitable trial principle for the trial pyramid. Only in this way can the harvest be the greatest.

The last time Chu Fei broke through the seventh level, he went to the "mountain road" next to him to learn a method of negative pressure flight, and finally broke through.

The negative pressure flight model is just one of the tens of thousands of models on the entire trial pyramid.

Just learning such a negative pressure flight model makes Chu Fei's flying ability the best in the hundreds of kilometers around Feihu City.

What if I learn a few more models?

Also, Chu Fei failed when he challenged the eighth floor last time. Although he got 155 points out of 200 points in the additional questions, Chu Fei was unwilling to accept it.

Because, in actual combat and survival battles, there is no such thing as passing, good, and excellent.

In actual combat, it is either full marks (victory) or zero marks (failure or even death).

Does it mean that during the battle, the enemy will appreciate you and think that you have 70 points, so only 70% of the head will be cut?

So this time Chu Fei has a small ambition, that is, to try to challenge the eighth floor again and try to break through completely!

I don't want to pass, excellent, or good, I just want full marks!

For a true genius, full marks are the only choice.

And in actual combat, only those with full marks can survive.

Sometimes, things are really black and white.

Because of this idea, Chu Fei regarded the failure of the last challenge as a "death"; now, Chu Fei is going to have a resurrection match!

A very realistic idea, but also a very simple idea.

With this idea in mind, Chu Fei walked into the gate of the trial pyramid step by step and began to move forward along the stairs.

There were different sculptures on the roadside, and each sculpture had a large number of formulas, data structures, etc.

Although it was not the first time he saw it, Chu Fei couldn't help but be shocked in his heart.

This is not a sculpture, it is an entity for each set of data architecture! And each entity is a "solution"!

At first, it was just the simplest and standard Euclidean geometry, and then it gradually became complicated, and combinations began to appear, and then non-Euclidean geometry.

Chu Fei walked very fast, and the universe brain was calculating frantically. At the beginning, these models only took a few seconds to complete the analysis and record them.

At the same time, he also used the camera function of the bracelet to take pictures for preservation.

But as the structure of the statue became more and more complex and the data architecture became more and more sophisticated, Chu Fei's forward speed gradually decreased.

After studying for a while, Chu Fei suddenly looked up at the towering trial pyramid. Thinking of the tens of thousands of models here, and calculating that there were only seven days at most, a trace of anxiety appeared in his heart.

Looking at the consciousness space again, the wisdom tree seed was spinning happily, and a drop of wisdom dew was condensing.

Before this, because he had already read all the conventional knowledge, it was difficult for Chu Fei to condense wisdom dew. But after entering here, it took only a short time to condense 7 drops of wisdom dew!

"Speed ​​up!"

Chu Fei took a deep breath, began to use the reserved wisdom dew, and began to burn the spiritual power.

Thanks to the wisdom tree seed, the spiritual power Chu Fei obtained was like the wisdom dew, suspended around, and it was burned directly when used.

In other words, although the wisdom tree seed is very low-key, it is providing assistance to Chu Fei's practice and progress every moment.

At this moment, the wisdom dew and the spiritual power are burning at the same time. Chu Fei's thinking speed has exploded, and the thinking height has also been instantly raised to 10.0, or perhaps higher.

Under this extreme overclocking state, Chu Fei's learning speed increased by dozens of times.

The powerful Eagle Eye spell allowed Chu Fei to see the details of the sculpture, the formulas and contents on it at a glance.

The eyes can scan dozens of sculptures in an instant.

In order to be more efficient, Chu Fei flew directly, using negative pressure flight, dragonfly flight suspension techniques, etc., to circle around the sculpture.

However, using spells and abilities in this way, coupled with the crazy calculations of the cosmic brain, made Chu Fei's physical energy consumption rapidly, with a physical energy consumption of up to 0.4~0.6 calories per second, an average of 0.5 calories.

30 calories per minute, up to 1800 calories per hour.

In fact, as the model becomes more and more complex, Chu Fei has to fly more circles to scan data, and physical energy consumption is constantly increasing.

At the critical moment, you can't let down the chain!

Chu Fei immediately activated the "Dawn 7.1" version of the program to replenish physical energy by devouring zombie crystal cores.

Zombie crystal cores not only have energy, but also have effects similar to elf fruits. These energies are more similar to life energy and can quickly restore physical energy.

Under such an effect, Chu Fei only took four hours to analyze more than 5,000 models on the first layer. More than 5,000 models almost cover the basic geometric shapes commonly seen in nature.

After the "exam", he entered the second layer, which was a changing geometric shape.

But halfway through the second layer, the sky suddenly turned dark, and it was night.

Without thinking, he took out the lighting tools from the storage space and continued to study and learn.

After another exam, he entered the third layer, which was the appearance of the creatures. The appearance of the creatures is more complicated. But this layer is mainly plants, etc.

At the fourth layer, animal data began to appear. Here, Chu Fei saw the shark scale structure that he had been thinking about.

But Chu Fei did not have much joy at this time, he just took note and continued his crazy research.

At this point in the research, Chu Fei entered the dimensional space until late at night the next day.

The higher you go, the more difficult it is.

Here on the fourth floor, Chu Fei found traces of strange beasts. According to the records here, thousands of years ago, there were not only sculptures but also animal entities. Simply put, it is a model.

But unfortunately, only sculptures were left on the fourth floor, and the animals were probably dead or ran away.

When he reached the fifth floor, Chu Fei finally saw a living beast. Unfortunately, the beast turned around and ran away when it saw Chu Fei.

Chu Fei didn't have time to chase these beasts, but wrote down the formulas and sculptures and took photos, and then continued to move forward.

The sky darkened and then brightened. On the third day of entering the dimensional space, Chu Fei finally came to the sixth floor.

The sixth floor is the information of general science and technology, entering the era of human civilization. There are more materials.

Chu Fei didn't have time to check them one by one, so he could only pay attention to some of them with key marks. The rest can only be photographed and preserved.

Unlike the previous floors, the sculptures on the sixth floor began to highlight the key points.

The key points are mainly those representative technologies that have promoted the progress of human civilization.

However, the rest of the technologies are not bad, and the ones that can be placed here are typical technologies; it can only be said that some are very important, some are more important, but all are important.

Chu Fei took a quick look and then entered the seventh floor.

The seventh floor is the peak technology and the corresponding technical principles. The content here is more profound and difficult to understand, and it seems that the construction has not been completed. Many sculptures are only semi-finished products - it should be said that there is no "solution".

When it comes to the eighth floor, it is the research of scientific theories and the corresponding data structures, which have begun to enter the "abstract field".

How to use mathematics, a pragmatic science, to explain abstract things?

The eighth floor discussed this, but in the end no "solution" was given, just a discussion.

But the eighth floor still gave a direction to work on - creation!

Since the abstract is not easy to understand, I will give it a concrete form. And this is creation!

After the eighth floor, Chu Fei passed another exam and finally reached the top again.

I thought the ninth floor would be bare, but I didn't expect a "music box" to appear in the center, and a pair of little people were slowly rotating in it.

A voice appeared in the music box: "This is the most perfect human body, the most perfect human body deduced by technology for the time being, and the best people will be rewarded."
