Meng Chao nodded: "I know, such as insects or annelids, their nervous systems are very primitive, and the speed of information transmission is extremely slow, about one meter per second, while the speed of human neural information transmission can reach 100 meters per second, which is 100 times that of low-level organisms, no wonder it can produce sparks of wisdom in the collision of neural information." ”

"That's right, the reason why the neural information transmission speed of humans and other advanced animals is so fast is because there is a layer of 'myelin sheath' outside the axons of our nerve cells, and the myelin sheath can be insulated to prevent nerve impulses from being transmitted from neuronal axons to another neuron axon, in addition, it can also use the mechanism of 'jump conduction' to speed up the transmission of action potentials."

Gao Ye thought for a while, and made an analogy, "If the nerves of lower animals are a potholed village road, and if you are not careful, the car will drive out of the highway, then the nerves of higher vertebrates like humans wrap the myelin sheath, as if the highway is lifted and closed, turning into an 'information superhighway', and the transmission speed is naturally hundreds of times faster."

"And the transcendent, by absorbing spiritual energy, constantly refining the nervous system with aura, and gradually forming a 'spiritual vein' or even a 'crystal vein' in the body, it is equivalent to upgrading the 'highway' into a 'high-speed railway', and the neural information transmission speed of high-level transcendental people can even reach a terrifying kilometer per second, whether it is logical deduction ability, calculation power or comprehension ability, it is naturally ten times stronger than ordinary people.

"However, evolving the myelin sheath is not the only way to give birth to wisdom.

"A lot of animals have chosen another evolutionary path, which is to keep thickening the diameter of nerve fibers.

"Scientific studies have proven that the diameter of nerve fibers is directly proportional to the speed at which nerve information is transmitted.

"The best examples of this are octopuses and squid.

"The thickest axonal fibers in human beings, no more than 20 microns in diameter, need 50 strands to be close together to barely reach one millimeter and be recognizable by the naked eye.

"And the huge axonal fibers of some squid, with a single diameter, reach a millimeter, which is fifty times that of humans.

"Even without a myelin sheath, such a thick nerve gives octopuses and squid a high degree of intelligence.

"They are the most cunning creatures in the ocean, and even use a variety of tools – as early as the Earth era, marine biologists have found that some octopuses, when hunting their favorite oysters, will use their soft tentacles to roll up pebbles on the shore, throw pebbles into them when they open their shells, jam the shells, and then calmly devour the soft bodies of the oysters.

"It's a kind of intelligence that a lot of vertebrates don't have.

"It's no wonder that many people say that octopuses are the most alien-like creatures on Earth, and that they may not be able to evolve another kind of intelligence that is very different from humans without human interference.

"We were also puzzled when we traveled to another world and saw snakes, insects, rats and ants with a body length of more than one meter, especially huge insects, arthropods and mollusks.

"Because according to the research of the Earth Age, the organs and body structure of insects cannot maintain a body size of more than one meter at all, even if they are not crushed by their own weight, the fatal injury of nerve transmission speed will make their reactions extremely sluggish.

"But after we captured and dissected some of the insect monsters, we found that their nerve fibers are similar to those of octopuses and squid on the earth, and the diameter of their nerves has expanded a hundred times to cope with such a huge body and perform agile and fast movements."

Meng Chao nodded thoughtfully: "So, when concocting the giant sandworm, inserting the genetic fragments of the octopus or squid to make the nerve fibers of the giant sandworm swell to the limit can improve its intelligence?" ”

"Yes, the giant sandworm concocted by our 'Spirit Creature' can reach a diameter of more than 3 millimeters in diameter, which is enough to understand all kinds of complex instructions."

Gao Ye paused for a moment, and then said, "If the myelin sheath is wrapped around the nerve fibers of the giant sandworm, its wisdom can be further improved, even to the level of pet cats and dogs." ”

Meng Chao took a deep breath: "What! ”

Takano said: "There are only two ways to improve wisdom, either to thicken the nerves like an octopus, or to wrap the myelin sheath like a vertebrate, but if the two schemes can be fused together and the myelin sheath can be wrapped around the incomparably thick nerve fibers, how terrifying the speed of nerve transmission can be - aren't you curious?" ”

Meng Chao swallowed with difficulty: "Your company shouldn't be conducting research in this area, right?" ”

"Nope."

Gao Ye's face was full of regret, "I really want to concoct this super intelligent giant sandworm, but Xie Xiaolei feels that it is not necessary, because in the commercial market, there is no suitable buyer."

"At the end of the day, he is a businessman and does everything from the perspective of interests, and I can only respect his opinion."

"I think ......"

Meng Chao said, "It's better not to conduct research in this area, otherwise, don't you think it's dangerous to create a giant sandworm that is smarter than humans?" ”

"I don't know which is more dangerous, a monster with intelligence or a monster that is completely ignorant and driven by the killing instinct."

Takano said, "Have you ever seen the insect tide, dense snakes, insects, rats and ants, forming a mighty black wave, rushing forward and hitting the human defense line one after another, no matter how many of the same kind are torn to pieces, burned to charcoal, and electrocuted to sparks, there is an endless stream of successors.

"In the end, thousands of insects were wiped out, but humanity also suffered heavy casualties.

"Why is this happening?

"Because the insect tide has no wisdom.

"Those bug monsters are mere flesh and blood machines that encapsulate some kind of command, they have no consciousness, no intelligence, no concept of 'survival' and 'death', and they don't have the slightest fear when bullets shred their bodies.

"I think that's the scariest thing.

"If we can give some wisdom to the lower creatures, not too high, as long as they understand the preciousness of life, understand the horror of human weapons, and even understand that 'it is better to be a slave of mankind than to be an enemy of mankind', such a simple truth, maybe the monster war can be solved in another way?"

Meng Chao hesitated.

With a population of tens of millions, even if it can be conquered, it is destined to be impossible to rule an entire planet with abundant spiritual energy and extremely fast evolution and mutation.

This is the consensus of many people.

Faced with the question of "how to conquer and rule the other world", people of different professions, different forces, and different interests gave different answers.

In the Agricultural University, which is known as the "Monster University", "give monsters a certain degree of wisdom, turn fierce beasts and monsters into spirit beasts and pet beasts, and let them 'drive the king', serve as cannon fodder, slaves, tools, partners, and allies of the Earth Army, and finally conquer the other world", this argument is very marketable.

From Takano's standpoint, it is normal to have such thoughts.

It's just that thinking of the damage caused to Dragon City by the "Nine Demon Gods" in the memory fragments of his previous life, Meng Chao is still faintly uneasy.

"I still can't imagine what kind of impact and change it will bring to our civilization once a monster is more intelligent than humans." Meng Chao muttered.

"Meng Chao, you're thinking too far."

"The speed of nerve transmission is only the basis for the birth of wisdom, and it does not mean that as long as a sufficiently thick nerve fiber is wrapped in a myelin sheath, wisdom can be produced instantly."

"On the one hand, the brain structure of the giant sandworm is very primitive, very different from the highly developed brain of humans, even if the flow of information can run around at high speed in its intricate huge neural network, without a real brain to analyze and integrate, information still cannot become intelligent.

"Even if we genetically modify the giant sandworm to have a larger, real brain, this is just 'hardware'.

"In terms of 'hardware', in the Stone Age millions of years ago, the brain volume, number of neurons and sulci circuits of ancient humans were almost the same as those of modern humans.

"But it is absolutely impossible for the people of the Stone Age to have the wisdom of modern humans.

Because wisdom is not only the collision of neural sparks, but also the accumulation of thousands of years of history, as well as the sum of complex social relations.

"Throwing a normal, healthy modern human infant into the wilderness, assuming that he never dies and thrives until he is eighteen years old, he is unlikely to have the slightest intelligence.

"Teleporting a strong Stone Age primitives to today's Dragon City, he is unlikely to pose the slightest threat.

Therefore, it is unfounded to think that if the giant sandworm has enough developed nerves and brains, it can instantly have wisdom, and even deeply understand human civilization, and become like human beings with seven emotions and six desires and strong ambitions.

"In the final analysis, wisdom is not necessary for survival, if the giant sandworm can live comfortably by devouring garbage and rocks, it is not necessary, uninterested, and impossible to produce true wisdom."

Meng Chao thought seriously about Gao Ye's words.

I have to admit that this giant sandworm expert is reasonable.

So, what is going on with the giant sandworm that evolved into a demon god in his previous life?

In the middle of the silence, in the laboratory, two researchers wearing negative pressure protective suits transmitted the test results.

Gao Ye looked at it, his face was gloomy, and he cursed in a low voice.

"How?" Meng Chao hurriedly asked.

"I knew it."

Takano said, "Someone injected a virus into the giant sandworm!" ”

Meng Chao thought for a while: "Are you sure it's man-made, not a virus infected in the wild?" ”

"Definitely not."

"More than a dozen natural subtypes of the mutant rabies virus can be transmitted between humans and animals, but the new variant of rabies virus found in the giant sandworm cannot be transmitted to humans - it is not a product of natural mutation, but a product developed in a human laboratory." ”
