Metal-based organisms are called metal-carbon-based organisms. The enzyme system in this type of organism has been incredibly modified. In the specific proteins that make up their bodies, the skeletons connecting amino and carboxyl groups in some amino acids are not carbon elements, but specific metal elements. Another part of the amino acids forms complexes with metal ions.

Since the ability of metal elements to lose electrons is not equal to their ability to gain electrons, the proteins expressed by the original human genes will produce extra electrons when expressed in this life system. Under the order of life, these proteins are arranged in specific ways in specific areas.

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

For example, the structure of the "brain-computer barrier".

Metal-based cells have damage resistance that far exceeds that of carbon-based cells native to Earth. It is also very resistant to hypoxia and has a longer life.

However, Shang Shang does not think that metal-based plants have more competitive advantages on this planet.

The reason is very simple.

Most metal elements in metal-based organisms have extra carbon atoms in their outer electron shells. Therefore, the radius of these atoms is naturally larger than that of carbon atoms. This also leads to a higher degree of freedom when this type of polypeptide folds into a protein, and the final folded product is more complex and requires higher energy to shake its structure.

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

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

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

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

Xiang Shan remembered that the standard human body temperature is generally around 50 degrees Celsius.

All other metal-based organisms face this problem.

They require higher reaction temperatures.

But here's the problem.

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

According to the first law of thermodynamics, the increase in 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.

Human beings can rely on a developed industrial base to use electricity to meet this energy demand.

But most organisms in nature do not have this condition.

This is also the reason why Xiangshan 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 the earth.

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

Under normal circumstances, it is impossible for metal-based organisms to form large-scale populations in the wild on earth.

If it's near the equator, it might still be possible.

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

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

Just like every time there is a mass extinction, giant species such as Tyrannosaurus rex are wiped out, while small species survive in large numbers. The population competitive advantage brought by "energy saving" is really too great.

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

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

Without external interference, customized metal-based species such as the "Copper Sugar Tree" would not be able to eliminate the earth's native carbon-based species on the earth.

Baseline Homo is simply able to play a stronger role in an industrialized society than Homo sapiens.

Yuki nodded.

He still remembered what Xiangshan said to him many months ago.

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

Xiang Shan nodded: [The higher the latitude, the colder it is. For metal-based organisms whose enzyme systems have high temperature requirements, the disadvantages are even more obvious. If you think about it carefully, maybe the frigid tundra is now the greenest place on earth. 】

Cui Kui exclaimed: [Senior is really well-informed...]

"Okay, that's it for this level."

Xiang Shan looked inside. There were one or two shack-like buildings on the floor, but not all of them were occupied. Two or three shacks were occupied.

This was probably a home built by homeless people a long time ago.

Xiang Shan led a group of people inside. There is a large shack. He pointed at the big shack: "This is it. Put down your luggage and go and demolish a few shacks nearby and repair them. This will be our current base."

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

"Yeah! Yeah! Ta! Don't be afraid!"

She said so.

"What a pity, I don't understand what you are talking about." Xiang Shan leaned down, patted the little guy's head, and then tidied up the doghouse-like shack a little.

Although there is surveillance around, in theory this is just the personal behavior of the lord. If you want to block surveillance, you are free to do so. And if this behavior arouses the suspicion of the lord, it is the individual's own fault.

Huang Coupler tries not to think about the adhesive of these cheap boards.

This move undoubtedly attracted the attention of the surrounding people. It's just that Xiang Shan, Cui Hui and Huang Couple are all fully prosthetic warriors, and Yuki's degree of transformation is not low. Compared with these natural people who have almost no decent transformation, they are simply too strong.

Those people will not take the initiative to provoke them.

Soon, a few people put together a shack big enough for four people to sit inside.

Xiangshan, on the other hand, nonchalantly laid the metal composite plates he carried with him on the inner wall of the shack. When necessary, these gadgets can withstand small-caliber gunfire, which is considered "better than nothing."

"Let's have a good rest today." Xiang Shan said: "We still need a day or two to get familiar with the city, collect information, and make complete preparations."

Xiang Shan said this.

Then it’s time to rest.

Although for the knights, Jayhawk City is full of crises, long-term emotional tension may still cause people to fall into a negative state and make various mistakes. Rest is also necessary.

Cui Ku still needs to train himself and restore his internal strength. And Yuki is busy training.

Huang Youguang took the little guy and was on guard outside.

Xiangshan entered a state of meditation again, using the new version of the online meditation room to extend his will.

This time still found nothing. The mysterious internal skill master I met last time seemed as if he had never existed.

Xiangshan was not depressed. He changed his mind and connected to another website.

That's a blockchain.

That mysterious existence not only gave Xiangshan the latest version of the online meditation room, but also left some information.

Those materials point to several famous blockchains that exist on the Internet.

Xiangshan soon realized that these blockchains should have been established after he fell asleep. He himself knew some about blockchain - of course, he only remembered it after seeing these addresses.

This ensures that he can obtain martial arts at any time.

Among the blockchains that the mysterious man gave him, there were three martial arts: "Mecha Steel Fist", "Kalashnikov's Style of Gun Fighting", and "Rebel's Strange View".

These three martial arts are the oldest cyber fighting technique, the oldest gun fighting technique, and the oldest shaping internal strength and mental technique.

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

Over the past two hundred years, famous masters have continuously uploaded their martial arts experience and updated versions to the blockchain in Xiangshan's memory.

However, this also brings huge problems.

The blockchain will fork.

Let's put it this way, blockchain can be imagined as a set of "rules" shared by everyone in the world to write a huge content. In the era when it was first born, this "content" was the "ledger". In the subsequent era, this "content" was the "martial arts secrets".

Since the blockchain is naturally decentralized, it is difficult for powerful people to delete it based on their own will.

This ensures that martial arts can be passed down forever.

And many times, this "rule" can be realized by "application".

One day, an application is suddenly upgraded and some table structures that are not recognized in the previous version are added. What will happen?

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

This is "bifurcation".

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

But blockchain is different.

Knights choose it to save secrets precisely because it is decentralized and the cost of deletion is too high.

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

That's something only centralization can do.

Therefore, blockchain is inevitably "forked".

This is also one of the inherent flaws of the blockchain ledger - in that era when humans were crazy about mining virtual mineral deposits, relatively short forks were constantly being abandoned.

As for the blockchains that Xiangshan remembers, the problem is even more serious.

People all over the world are uploading their martial arts experience to it. And a considerable number of these uploaders have achieved internal strength, or have their own understanding of internal strength.

This leads to...the "rules" of "packaging cheat blocks" can never be unified.

The ancient blockchain in Xiangshan’s memory had too many hard and soft forks, which was too scary.

It's also about Mecha Steel Fist. The ancient blockchain that Xiangshan remembers is like a summary of content at the academic database level. It's very complicated, and you have to start from the oldest version and keep looking for the source of this boxing. The path of evolution.

But the one the mysterious man gave him was completely different.
