Metal-based organisms, the full name of metal-based-carbon-based organisms. The enzyme system in this type of organism has undergone an incredible modification, and the backbone that connects amino and carboxyl groups in some of the proteins that make up its body is not carbon, but specific metals.

Since the ability of metal elements to lose electrons is not equal to the ability to gain electrons, the proteins expressed in the original genes of human beings will produce additional electrons when they are expressed under this living system. Under the order of life, these proteins are arranged in a specific way in a specific area.

Therefore, the protein complexes of metal-based organisms will exhibit the characteristics of some metal clusters.

For example, the "brain-computer barrier" is a structure.

Metal-based cells have a resistance to damage that far exceeds that of carbon-based cells, a native species of the planet. It is also highly resistant to hypoxia and has a longer lifespan.

However, Upward does not believe that metal-based plants have a competitive advantage on this planet.

The reason is very simple.

Most of the metal elements in metal-based organisms have excess carbon atoms in their outer electron layers. These substances participate in the reaction, which requires higher energy levels.

The enzyme systems of metal-based organisms need to operate in a higher energy environment.

The body temperature of the baseline human is much higher than that of Homo sapiens.

Of course, the temperature at which proteins are denatured is also much higher than that of Homo sapiens.

A temperature of 37 degrees Celsius is enough for most metal-based proteins to lose their reaction conditions.

Xiang Shan remembers that the base human body temperature is generally around 50 degrees Celsius.

All other metal-based organisms face this problem.

They require a higher reaction temperature.

But herein lies the problem.

"High body temperature" cannot appear out of thin air.

According to the first law of thermodynamics, the increase in the internal energy of an object is equal to the sum of the heat absorbed by the object and the work done on the object. If you want high temperatures, you need more energy.

Humans can rely on a well-developed industrial base to use electricity to meet this energy demand.

But most creatures in nature don't have this condition.

This is also the reason why Xiang Shan and others dared to carry out this kind of genetic modification on animals. Because, in theory, even if those experimental animals escape, it will be difficult for them to successfully reproduce on Earth.

Native species may not have as strong damage resistance and combat effectiveness as them, but they are better at "energy saving" and have a greater competitive advantage.

In general, it is impossible for metal-based organisms to form large-scale populations in the wild on Earth.

If it's near the equator, there's probably a little bit of possibility.

After all, carbon-based organisms can also be found in the Antarctic and the Arctic.

But no matter what happens without human intervention, metal-based organisms cannot eliminate native species from the earth's environment without developing a civilization.

Just as every time there is a mass extinction, all the giant species such as Tyrannosaurus rex are on the streets, and the small species survive in large numbers, the competitive advantage of the population brought by "energy saving" is too great.

Xiang Shan remembers that he relied on this reason to convince biologists who were committed to protecting the ecology.

And he insists that "plants should be green" for the same reason.

If there is no external interference, it is impossible for the "copper sugar tree", a customized version of the metal-based species, to eliminate the earth's native carbon-based species on the earth.

Baseline humans are simply capable of playing a stronger role than Homo sapiens in industrialized societies.

Yuki nodded.

He still remembered what Xiang Shan had told him months earlier.

Cui said: [At this latitude, green plants may still be rare. But there are still some ...... over there in the Arctic Circle]

Xiang Shan nodded: [The higher the latitude, the colder it is. The disadvantages of metal-based organisms with high temperature requirements in enzyme systems are more obvious. If you think about it, maybe the tundra is the greenest place on the planet right now. 】

Cui Yu exclaimed: [How well-informed are ......the seniors]

"Alright, this is it."

I looked inside the mountain. There are still one or two shacks on the floor, but not every one of them has people inside. Two or three shacks were occupied.

I think this is the homeless man built a long time ago.

Xiang Shan led the group inside. There is a large shack. He pointed to the big shack, "That's it." Put your luggage down and go to the side to dismantle a few shacks and tinker with them. This is the base for this stage. ”

Yuki put down the little guy in his hand and went with a few other people to tear down the surrounding shacks. Xiang Xiang looked at the little one, and the little one also tried to raise his head to look at Xiang Shan.

"Yikes! Yikes! Da! Don't be afraid! ”

She said.

"Unfortunately, I don't understand what you're saying." He bent down on the mountain, patted the little one's head, and tidied up the kennel-like shack a little.

Despite the surveillance, however, this is theoretically only the personal behavior of the lord. You want to block the surveillance, it's your own freedom. And if this behavior arouses the suspicion of the lord, it is also a personal blame.

Huang Coupling tries not to think about what the binders of these cheap sheets are.

This move undoubtedly attracted the attention of the surrounding area. It's just that Xiang Shan, Cui Ji and Huang Coupleguang are all completely prosthetic warriors, and Yuki's degree of transformation is not low. Compared to these natural people who have almost no decent transformation, it is simply too strong.

Those people will not take the initiative to provoke them.

Soon, the few of them had built a shack large enough for all four of them to sit in.

Xiang Shan, on the other hand, did not care about laying the metal composite sheet he carried with him on the inner wall of the shack. When necessary, these things can withstand small-caliber gunfire, which is "better than nothing".

"Let's get some rest today." Xiang Shan said: "We still need a day or two to familiarize ourselves with the city, listen to the information, and be fully prepared. ”

Xiang Shan said.

Then it's time to rest.

Although Pine Eagle City is full of crises for knights, it is still possible for people to fall into a negative state and make various mistakes after a long period of emotional tension. Rest is also necessary.

Cui Ji also needs to exercise himself and restore his internal strength. Yuki, on the other hand, was busy training.

Huang Couplelight took the little guy and guarded outside.

Xiang Shan once again entered a meditative state, with the help of a new version of the online meditation room, to extend his will.

This time it was still nothing. The mysterious master of internal strength that I met last time seemed to never exist.

Xiang Shan was not depressed. He thought about it and connected to another website.

That's a blockchain.

That mysterious existence not only gave Xiang Shan the latest version of the Internet meditation room, but also left some information.

Those materials point to several well-known blockchains that exist on the network.

Xiang Shan soon realized that these blockchains should have been built after he had fallen asleep. He knew a few blockchains himself — and of course, he remembered them when he saw them.

This is to ensure that no matter when, he can get martial arts.

Among the blockchains given to him by the mysterious man, there are three martial arts: "Mecha Steel Fist", "Kalashnikov Drift Gun Fighting Technique", and "Traitor Heterochromatic View".

These three martial arts are the oldest cyber fighting technique, the oldest spear fighting technique, and the oldest forming internal martial arts method.

The "ancient" here does not mean that they are weak. Of course, the original version of these three martial arts is indeed very weak compared to today's martial arts. However, they themselves are constantly iterating.

In the past 200 years, there have been celebrities who have uploaded their martial arts experience and their own versions to the blockchain in Xiangshan's memory.

However, this also poses a huge problem.

Blockchains are forked.

Let's just say that blockchain can be imagined as a world where everyone shares a common set of "rules" to write a huge piece of content. In the era when it was first born, this "content" was the "ledger". In the subsequent era, this "content" is the "martial arts cheats".

Since blockchain is inherently decentralized, it is difficult for the powerful to modify it on their own.

This guarantees that martial arts can be passed on forever.

And in many cases, this "rule" can be implemented by "application".

What happens if one day an application suddenly upgrades to some table structures that weren't recognized in the previous version?

This new version of the application will continue to package blocks that are not recognized by the "old version of the application", creating a completely different link from the old version of the packaged block.

This is the "fork".

In the traditional centralized software system, since the data storage is centralized and the version management is also centralized, if there is a major upgrade, it can be set to "you can't log in without downloading the new version" to ensure that users are always using the correct version.

But blockchain is different.

Chivalry chose it to save cheats precisely because it is decentralized, and the cost of deletion is too huge.

But this also means that you can never guarantee that all users will always use only one "uniform rule" to package blocks.

That's something that only centralization can do.

Therefore, the blockchain will inevitably "fork".

This is also one of the inherent flaws of the blockchain ledger - in that era of human frenzied mining of virtual mineral deposits, there were constantly shorter forks being abandoned.

And the blockchains that Xiang Shan remembers, the problem is even more serious.

The whole world is uploading martial arts tips on it. And among these uploaders, a considerable number of them have achieved internal merit or have their own understanding of internal forces.

As a result, ...... "rules" for "packing cheats blocks" can never be harmonized.

The ancient blockchain in Xiangshan's memory, there are too many soft and hard forks, and they are too terrible.

It's also Mecha Steel Fist, the ancient blockchain that Xiang Shan remembers, it's like an academic database-level content summary, which is very complicated, and you have to start from the oldest version and keep looking for the evolution of this boxing technique.

And the one given to him by the mysterious man is completely different.
