metaverse evolution.

When Chu Fei returned to Feihu City, he did not wait for Li Guangyu.

The reason why I passed by Black Iron City when I went there was because I didn't want to lose my temper, and I wanted to pick up a cannon fodder who could fight against the tide of living zombies... ahem... comrades.

Now that the negotiations are over, there is no need.

This isn't about burning bridges, it's just about being too lazy to deal with irrelevant matters.

Perhaps, this should be regarded as dusting, at least occasionally.

In fact, miscellaneous tasks are tiring and take up a lot of computing power.But for Chu Fei, these things are completely unnecessary.

As long as I am strong enough, others will come to please me!

The straight-line distance from Hongcheng to Feihu City is about [-] kilometers. Chu Fei flew slowly and returned safely in only one and a half hours, just in the evening; during this period, he also bypassed Black Iron City and flew a little longer. .

Back at Shuguang Academy, because Wu Yong was practicing in seclusion, Chu Fei first reported to his senior brother on the negotiation situation, and then came to the Shuguang Special Forces Team.

Huang Gang was guarding the door for Zhao Hongyue, and it turned out that Zhao Hongyue was breaking through the awakened ones.

Chu Fei chatted briefly and found that there was no problem, and then found a big package at the Dawn Special Forces.

The package was placed in a newly built two-story villa. This was a newly built house for Chu Fei by the Dawn Team and even Dawn Academy. It was a new research laboratory. Many rooms in it had already been equipped with a large number of instruments and equipment.

Although Chu Fei already has a "mansion" on the mountain, Chu Fei prefers to stay here with the Dawn Team.

In fact, Chu Fei is somewhat sober in the world: if he is too high-minded, he will easily stumble!Moreover, being aloof is not a hero, and does not fit the character of a hero.

Moreover, Chu Fei is still training Huang Gang and Zhao Hongyue, and has even vaguely developed the Shuguang Special Forces Team into his direct lineage.

Since we are destined to migrate in the future, we must have a certain amount of team strength.

It is not impossible to fight alone, but if you have a choice, it is better to have a force of your own.

Not to mention that the current Shuguang team, especially Huang Gang and Zhao Hongyue, are about to "departure". Not only are they good at fighting, but the most important thing is that they have rich experience in life, management, combat, and survival. They will be very good helpers and partner.

As for this package, it was delivered from Dawn City yesterday. It was a computing module ordered by Chu Fei from the Iron-Blooded Mercenary Group. There were ten in total.

A computing module is actually a small server, one meter square, with a comprehensive floating point computing power of up to quadrillion levels, more than 30 times the computing power of Chu Fei's universe brain; ten servers connected in parallel can bring Chu Fei Three hundred times the computing power acceleration.

Of course, this acceleration of computing power cannot completely replace human computing power and thinking.

The ten servers have completed the basic configuration. Chu Fei only needs to follow the instructions to simply splice them together. It is a completely fool-proof operation.

There is only power supply and you need to match it yourself.

As we all know, buying a computer does not come with a generator. This is common sense.

In this high-tech apocalypse, power supply is actually very simple, just fuel cells.Fuel cell technology is relatively simple and can even be made by hand.

Fuel cells can use biogas, natural gas, various fuels, hydrogen, alcohol, etc.There is no shortage of these basic fuels.

For example, Feihu City has production lines for artificial fuel synthesis and wood distillation processes.

With the instructions in hand, Chu Fei installed the new computer before it got completely dark, and then... Chu Fei began to review the system source code.

As early as when he was in the Jagged Mercenary Group, Chu Fei reviewed the source codes of these computers and found more than 800 lines of questionable items.

To survive in the last days, one must not be afraid to speculate on this society with the greatest malice.

So Chu Fei thought about it and went straight to the virtual center of Shuguang Academy with these source codes.

It cannot be verified on the original computer. There is a high probability that these questions will be covered up or maliciously corrected. If you want to verify, it is best to go to another computer, preferably using a different operating system.

Coincidentally, the operating system and computer hardware of Shuguang College Virtual Center are different from this batch of equipment.

Importing the source code into the virtual center, Chu Fei began to calculate frantically.

First, create a virtual machine directly. Creating a virtual machine in a computer is not a new technology; it is not an advanced technology of secondary virtualization in dimensional space.

Chu Fei directly set up 10 virtual machines to run at the same time and quickly retrieved every piece of code - not just the suspicious ones.

First, delete part of the code to see if the system can run stably.

This method seems simple, but it is computationally intensive. More than 800 lines need to be continuously deleted or added, and different operation logic needs to be continuously run.

Fortunately, the virtual machines are very powerful. Ten groups of virtual machines can check 1 times in one minute. Chu Fei used this stupid method to eliminate more than 800 lines of more than 600 lines of code.

Of the remaining 200 or so lines, half of them passed the verification.There are still more than a hundred lines of questions that are even greater.

In addition, during the inspection process, more than 200 lines of problematic code were discovered.

This time, Chu Fei did not continue to use the computer to check, but found all the codes and related programs and verified them one by one in person.

Finally, three programs were deleted, involving more than 80 lines of code; there are still two programs that are not sure.

However, Chu Fei immediately found a similar program on the system of the virtual center, compiled it, replaced it on the new system, and deleted the original program directly.

Finally, run the modified program again, no errors are reported, and it runs stably.

At this point, Chu Fei showed a satisfied smile.

But this was not the end. Chu Fei went back to check the deleted codes and related programs to see what the ultimate purpose of these problematic codes and programs was.

There is a way to know yourself, know your enemy, and win a hundred battles. Chu Fei believes that there are not a few people who use this kind of small server, and most of them don't have the ability or knowledge to study code.

This is not Chu Fei's boast. He has received the inheritance three times, and there is a large amount of code knowledge system in it.

Here is a little trivia: In scientific research, especially in top scientific research systems, top scientific researchers often have strong computer programming capabilities.

Because in the top research fields, there are no computer tools, everything is lacking, and you need to make it yourself.

Chu Fei, who is determined to become a research-based awakener, will certainly not ignore this issue.In fact, this has always been Chu Fei's focus.

In fact, previous iterations of thinking models also required strong computer programming capabilities, software programming capabilities, etc.

As time passed, Chu Fei gradually understood the purpose of these problematic codes:

Leave the back door!

And there are multiple backdoors!
As for the back door, it only needs a specific "key"—maybe a (program type) virus, maybe a secret key, etc., and it can easily affect the cosmic brain of an awakened person.

It can steal data, control invisibly, make people crazy, etc.If you think about computer viruses and computer backdoors, you will know how terrible such backdoors are.Some can even lock specific programs, files, etc., and even cause the computer to burn out due to overclocking, etc.

Thinking of the various events that had happened in another world and in the computer field, Chu Fei couldn't help but feel a little cold.

Sure enough, the end of the world is the end of the world, and even if it occasionally reveals a little dark side, it is enough to make people tremble from the soul.

Just imagine, if you fight someone who has mastered this loophole, and if someone shouts, your cosmic brain will go on strike. What a terrifying picture it would be.

Thinking divergently, the ordinary awakened people in the city broke out in an uprising and wanted to overthrow the capitalists. As a result, the capitalists were still holding a banquet and singing and dancing. One of them pressed a button, and the rebel army outside the city immediately shut down.

To expand a bit more...

In the virtual world, Chu Fei shook his head suddenly, shook off these thoughts, and started reverse engineering.

Reverse engineering is actually very difficult, but with his strong foundation and tens of thousands of calculations per minute, Chu Fei still resolved some secret keys.

The reason why it is "some" is because when complex operations are involved, usually multivariate equations, there is often more than one "solution".

Chu Fei then brought it into the new system for testing, and finally selected 7 secret keys.

These seven secret keys, after activating the backdoor, can directly control or interfere with some of the core logic of the Universe Brain, causing the Universe Brain to report errors, cause logic confusion, and even affect calculation accuracy.

Every secret key is a killer of the cosmic brain.

When daybreak came, Chu Fei stood at the door of the virtual center, thinking about the seven secret keys he had reverse engineered, feeling both proud and wary at the same time.

Looking at the crimson sky in the east, Chu Fei spoke leisurely and said to himself: "It seems that the inland area is more dangerous than the fringe area.

The dangers in the fringe areas come from wilderness, strange animals, etc.;

The danger inland comes from humans themselves.

Humans are the most terrifying creatures in this world! "

But Chu Fei immediately showed a firm expression, "It's a lot of fun fighting against the sky, it's a lot of fun fighting with the earth, it's a lot of fun fighting with people!!!"

After adjusting his mentality, Chu Fei strode down the mountain.

On the way, I met the senior brother, who was formally dressed and accompanied by a few people who handled chores. Among them, Chu Fei saw the people in charge of purchasing from Shuguang College.

What is this for?
Chu Fei said hello, and the senior brother responded with a smile, "Junior brother, I am going to take people to Hongcheng to negotiate the details. Is there anything else that needs attention?"

So that’s it.Chu Fei thought for a while and said: "Hongcheng looks good now, but in fact it is already in dire straits. But the top management of Hongcheng still wants to save Hongcheng, so they are willing to pay some price.

But now Hongcheng has gathered at least four 10.0 masters, and they should not be insulted lightly. "

The senior brother understood immediately, thanked Chu Fei, stretched out the people around him and walked down the mountain.

Chu Fei went to Hongcheng mainly to "check out the points", mainly to take the lead and determine the cooperation policy between the two parties.The senior brother implemented the details based on Chu Fei's negotiations.

The conditions that Chu Fei and Hong Cheng talked about may be hundreds of thousands of words, and the result of the negotiations between the big brothers may bring back a thick book, which may contain 10,000+ words, or even hundreds of thousands of words.

Especially some technical details, etc.

However, Chu Fei felt a little emotional about these: This is the privilege of the strong.

A strong person only needs to practice with peace of mind, but people like the senior brother need to go through the labor of writing documents. They couldn't keep up with their practice originally, and they can't keep up now.

"So, the stronger you are, the stronger you are!"

While Chu Fei was thinking, he spread his wings and flew down the mountain.After a while, he returned to the new research laboratory - a villa-level research laboratory that he opened and built by himself.

Ordinary people want to own such a research laboratory, not to mention the money spent, just searching for various instruments and equipment is a headache.

Therefore, becoming stronger is the only way out.

Returning to the research room of Shuguang College, Chu Fei reinstalled the system on the computer and readjusted the parameters.After a busy half day, the new virtual center was up and running.

Because there are no backdoor programs, computer performance has improved by 1.5%!
This set of computers itself has more than 300 times the computing power of Chu Fei's cosmic brain. An increase of 1.5% is enough to increase the computing power of Chu Fei's five cosmic brains. It is a terrifying improvement.

"Sure enough, only by mastering technology can we be nourished in the end of the world. It is technology that has changed mankind. We must adhere to the path of scientific development!"

Then, Chu Fei entered the virtual world and began to use the new computer to perform the techniques to break through 9.0.

Actually, Chu Fei doesn't want to break through to 9.0 right now, because the various research projects are not perfect, and the foundation is advancing by leaps and bounds, Chu Fei even wants to open the "secondary brain" before breaking through.

But because of the problem of the zombie tide, Chu Fei had to break through 9.0 first.

Anyway, in the future, we can use the "down-clocking compatibility" method to reduce the Cosmic Brain to a height of 8.0 and achieve a second breakthrough.

Chu Fei learned this from Wu Feng (Tian Feng).

Before becoming an awakened person, the iteration of Chu Fei's thinking model was to format the original one.

But after the Awakener, that is, after breaking through 8.0, it is inappropriate and unnecessary to format it again.

The downclocking compatibility mode is favored by Chu Fei.

However, Chu Fei has not officially started researching downclocking compatibility, but this does not prevent Chu Fei from breaking through 9.0 first!

As a crisis approaches, we must improve our combat effectiveness and survivability as soon as possible; then we can talk about other things.

Chu Fei strengthened his mentality and studied the next level of skills at full speed.

The newly built computer (virtual space) has a computing power even three times that of the Shuguang Academy Virtual Center!
With the help of this powerful computing power, Chu Fei used another drop of wisdom dew, and his thinking speed increased dozens of times.

Because it was his own computer, Chu Fei completely let go.

At first, it took the computer five minutes to complete one exercise calculation; but by the next day, the computer could complete hundreds of exercise calculations in one second.

At this time, the computer has accumulated a large amount of data and picked out all the problems that may be encountered in practice.

The enumeration method is a stupid method; but it is the optimal solution when the computing power is sufficient.

After all, computers do not have the thinking ability of humans, but they have parallel computing capabilities that are countless times greater than humans.

Thanks to the powerful computing power and deep knowledge reserves, Chu Fei completed the "preparation" that would take months or even years for others to complete in just one night.

It is said that a fool will always succeed after a thousand considerations, but this night the computer ran hundreds of millions of times!
Scientific practice, krypton gold is really effective. (end of this chapter)
