metaverse evolution.

Chu Fei greeted Wu Yong and Zhou Pengyue, then took the feathered snake and flew directly to Black Iron City.

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

In this chaotic moment, can Black Iron City stay?

This question has been lingering in Chu Fei's mind, and it is also an issue currently being discussed by the 150 million people in Dawn City.

At this time, I saw the Black Iron City again, only to see that the initial repairs of the Black Iron City had been completed. The collapsed walls had been repaired, and the crumbling walls had been reinforced.

Even an outward-turned guardrail is being installed on the top of the city, allowing the top of the city to turn outwards a little to increase the difficulty of climbing.

A large number of people, and even controlled alien beasts, were moving in and out of the city, making it a busy scene.

Black Iron City was able to complete the restoration in less than two months, thanks to the large number of alien beasts involved in the construction.

Someone came to meet Chu Fei at the gate of the city, and an old vehicle was used as a welcome vehicle.

When they arrived in the city, they saw that the houses were still very dilapidated, but 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 is doing everything possible to repair the city walls and resume industrial production.As for people's livelihood, etc., they are all put behind.

Fortunately, there is really no shortage of food in Black Iron City now.

Chu Fei saw a transport truck passing by. The truck body was made of welded steel bars. There were a large number of half-meter-long "silkworms" inside, entering a food processing factory.

These "silkworms" are carefully taken care of, and there are three people in the carriage responsible for them.

In food processing plants, "compressed biscuits" are constantly being output.

Chu Fei couldn't help but ask what this was.

Speaking of which, due to the special management of Black Iron City, intelligence work is completely impenetrable.

The person who responded said: "Those are bread silkworms. They can eat plant fiber and convert it into starch for output. Although it doesn't taste very good, it is indeed edible."

Chu Fei observed carefully again and found that it was indeed the case.

Those "bread silkworms" were munching on broken, wet sawdust and leaves, while "silkworm excrement" of three to four centimeters in size was rolling out and piled up behind them.

Silkworm excrement can be used as medicine, and of course it can be eaten!
So it’s not a big deal if this mutated bread silkworm has similar functions.

As for the taste, that's secondary.This is the end of the world, it would be nice to have something to eat.At least not the cockroach cookies from the movie.

Along the way, Chu Fei saw many factories.Chu Fei vaguely understood, was Hong Qingxin showing off his muscles?
After a while, they arrived at the city lord's mansion, and the feathered snake stayed outside, "fighting" with the three giant pythons in the yard through the air.

Chu Fei entered the hospital and saw Hong Qingxin again.

Compared with the last time, Hong Qingxin became more and more "human-like", his face was no longer so ferocious and terrifying, and his body had the calmness and majesty of a superior person.

When we met again after a month, the changes in Hong Qingxin were still obvious.

But Chu Fei changed even more. Hong Qingxin looked at Chu Fei with a hint of panic in his eyes.

Hong Qingxin felt a hint of danger in Chu Fei.

This dangerous aura gave Hong Qingxin a feeling of a ray of light on his back.

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

Chu Fei chuckled lightly, "Hong Qingxin, have you received the distress message from Hong Cheng?"

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

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

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

Hongcheng currently has a population of 180 million. If it is not saved, the scale of the zombie wave will expand to 180 million.

The most important thing is that the zombie queen and the senior zombies will absorb the life energy of 180 million people.

Can you imagine what that would be like? "

Hong Qingxin's face suddenly stiffened. After a while, he took a deep breath, nodded slowly, and spoke again, but his voice lacked a hint of indifference:
"What do you think we should do to save him? I can't think of a rescue method at the moment. All rescue methods are just scratching the surface.

A wave of more than 700 million living corpses!
More than 700 million! "

Chu Fei said calmly: "Whether the rescue can be successful is one thing, whether it can be saved is another.

We must save and show a firm enough attitude.

Only in this way can Hongcheng's self-rescue heart be stimulated and there be hope.

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

Hong Qingxin nodded slowly, thoughtfully. "I see, we can organize a team now. I don't know how long it will take you to build Dawn City?"

Listening to Hong Qing's new emphasis on 'City of Dawn', Chu Fei just smiled and said, "It also takes a day to prepare. It's still the motorcycle team from last time."

"Team Linyuan, I know." Hong Qingxin smiled, and countless thoughts flashed through his narrowed eyes.

Although the history of this Linyuan team is only one month, the achievements are really brilliant.

Chu Fei didn't care how much Hong Qingxin thought about Hong Qingxin. In fact, Chu Fei also had 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 inserting a knife 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 conditions 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 in terms of living corpses, and ordinary aircraft cannot support them safely 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 stored in the city lord's mansion at the beginning and was damaged by the old city lord. It should be destructive research. As for the password, the old I’m afraid the 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 loot, it is based on the points system.The points system has been implemented in Feihu City and surrounding areas for a long time. It has a mature model and is fair enough.

Chu Fei immediately sent the negotiation news back to Feihu City, where someone would naturally pass it on to Zhou Pengyue.What happened after that had nothing to do with Chu Fei.

Chu Fei has entered the dimensional space of Black Iron City. This is Chu Fei's second and last time to enter.

Coming to the dimensional space again, Chu Fei first took a deep breath and felt the rich and active life energy in the air. His thoughts were a little far away:
Is this what the so-called spiritual energy in the mythical world refers to?
Then he looked up at the nine-story peak and the towering nine-story trial pyramid in front of him, and was amazed again.After marveling for a while, Chu Fei finally uttered two words: Oh fuck!

Although it was the second time I entered, the shock was even greater than the first time.

Such a huge dimensional space can be opened for up to seven days at a time, and a large area within it has not been explored.

Chu Fei's purpose this time is to explore as much as possible. The lowest goal is to collect a large amount of information; the highest goal is to find inheritance like the underground space of Feihu City.

While thinking, Chu Fei had already spread his wings and started flying at full speed.

There is a strange mechanism in the dimensional space here. The sky is full of turbulence, which interferes with flight.
Now Chu Fei could face these turbulences calmly. He only saw that Chu Fei's flight path was winding but extremely fast. He flew a thousand meters away in the blink of an eye and began to search the earth.

With the experience from last time and 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 for testing the trial principles of the pyramid. Only in this way can you gain the most.

The last time Chu Fei broke through to the seventh floor, he went to the nearby "mountain road" to learn a negative pressure flying method before finally breaking through.

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

Just learning such a negative pressure flight model allowed Chu Fei's flying ability to surpass hundreds of kilometers around Feihu City.

What if you learn a few more models?

Also, Chu Fei failed last time when he challenged the eighth floor. Although he scored 200 points on the 155-point additional question, Chu Fei was not resigned to it.

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

In actual combat, either full points (victory) or zero points (failure or even death).

Could it be that when fighting, the enemy will admire you and think that you are 70%, so he only cuts off [-]% of your head?

So Chu Fei still has a small ambition this time, which is to try to challenge the eighth level of obstruction again and try to completely break through!
I don’t want to pass, nor do I want to be excellent or good, I just want full marks!
For true geniuses, perfect scores are the only option.

In actual combat, only those with perfect scores can survive.

Sometimes, things really are 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 thought, but also a very simple thought.

With such thoughts, Chu Fei walked step by step into the door of the Trial Pyramid and started walking along the stairs.

There are different sculptures on the roadside, and each sculpture has a large number of formulas, data structures, etc. on it.

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 creates an entity for each set of data architecture!And every entity is a "solution"!
At first it was just the simplest, standard Euclidean geometry, and then it gradually became more complex, with combinations starting to appear, and then non-Euclidean geometry.

Chu Fei walked very fast, and the cosmic brain was calculating like crazy. At first, it only took a few seconds to analyze and record these models.

At the same time, you can also use the bracelet’s camera capabilities to take pictures and save them.

However, as the structure of the statue became more complex and the data structure became more sophisticated, Chu Fei's forward speed also gradually slowed down.

After studying for a moment, Chu Fei suddenly looked up and looked at the towering Trial Pyramid. Thinking of the tens of thousands of models here, and calculating that there were only seven days at most, he felt a little anxious in his heart.

Look again in the space of consciousness, the seeds of the tree of wisdom are spinning happily, and a drop of dew of wisdom is gathering.

Before this, because Chu Fei had already seen all the conventional knowledge, it was difficult for Chu Fei to gather the dew of wisdom.But after entering here, it only took a moment to gather 7 drops of wisdom!
"Accelerate!"

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

Thanks to the seeds of the Wisdom Tree, the spiritual power Chu Fei obtained was like the dew of wisdom, suspended around him and burned directly when used.

In other words, even though the seeds of the Wisdom Tree are very low-key, they are helping Chu Fei's practice and progress every moment.

At this moment, the dew of wisdom and spiritual power were burning at the same time. Not only Chu Fei's thinking speed increased explosively, his thinking height also instantly increased to 10.0, maybe even higher.

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

The powerful eagle eye spell enabled Chu Fei to see clearly the details of the sculpture, the formulas and content on it at a glance.

The eye can scan dozens of sculptures instantly.

In order to be more efficient, Chu Fei flew directly, using negative pressure flight and the levitation skills of dragonflies to hover around the sculpture.

However, such use of spells and abilities, coupled with the crazy calculations of the cosmic brain, caused Chu Fei's physical energy consumption to be rapid. The physical energy consumption was as high as 0.4~0.6 calories per second, with an average of 0.5 calories.

1 calories are consumed in one minute, and up to 30 calories in one hour.

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

At the critical moment, don’t let anything slip!
Chu Fei immediately activated the "Dawn 7.1" version of the program and replenished his physical energy by swallowing the core of the living corpse.

The living corpse crystal core not only has energy, but also has effects similar to elf fruits. These energies are more similar to life energy and can quickly restore physical fitness.

Under such an effect, Chu Fei analyzed more than 5000 models in the first layer in just four hours. More than 5000 models cover almost all the basic geometric shapes common in nature.

After passing the "examination", you enter the second level, which is a changing geometry.

But halfway through the second floor, the sky suddenly turned black, and it was night.

Without a second thought, I took out my lighting tools from storage and continued researching and learning.

After taking another exam, we entered the third level, which is the appearance of living things.The appearance of living things is even more complex.But this layer is mainly plants and so on.

On the fourth level, animal data began to appear.Here, Chu Fei saw the shark scale structure that he had longed for.

But Chu Fei didn't feel much joy at this time. He just wrote it down and continued his crazy research.

After researching this point, Chu Fei entered the dimensional space late at night the next day.

The further up you go, the more difficult it becomes.

Here on the fourth floor, Chu Fei discovered traces of strange beasts.According to records here, thousands of years ago, there were not only sculptures, but also animal entities.Simply put, they are models.

But it is a pity that only the sculptures are left on the fourth floor. The animals are probably dead or ran away.

When he reached the fifth floor, Chu Fei finally saw the living beast.It's a pity that the strange beast turned around and ran away when he saw Chu Fei.

Chu Fei didn't have time to chase these strange beasts. Instead, he wrote down the formulas and sculptures and took photos before moving on.

The sky turned dark and brightened again. On the third day after entering the dimensional space, Chu Fei finally reached the sixth floor.

The sixth level is general scientific and technological data, which has entered the era of human civilization.There is more information.

Chu Fei didn't have time to check them one by one, so he could only pay attention to some highlighted ones.The rest can only be photographed and kept.

Different from the previous floors, the sculptures on the sixth floor begin to focus.
The focus is mainly on those representative technologies that have promoted the progress of human civilization.

But the rest of the technologies are not bad, and the ones that can be displayed here are all typical technologies. It can only be said that some are very important, and some are more important, but they are all important.

Chu Fei read it wholeheartedly, and then entered the seventh floor.

The seventh level is peak technology and 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".

By the eighth level, the study of scientific theories and corresponding data structures has begun to enter the "abstract realm."

How to use mathematics, a science that seeks truth from facts, to explain abstract things?
The eighth level discussed this, but ultimately did not give a "solution", but just discussed it.

But the eighth level still gives us a direction to work towards—creation!
Since it's difficult to understand abstractly, I'll make it concrete for him.And this is creation!
After the eighth level, after passing another exam, Chu Fei finally reached the top again.

I thought the ninth floor would be bare, but unexpectedly, a "music box" appeared in the center, with a pair of little figures spinning slowly in it.

A voice appeared in the music box: "This is the most perfect human body, the most perfect human body temporarily deduced by technology, and rewards the best people." (End of this chapter)
