Chapter 845 Dolphin

The dolphin was too fast - or rather, Xiangshan's prosthesis was too slow under the water. Although the drill dragon had designed the buoyancy device as close to fluid mechanics as possible, this prosthesis, which was mainly used for combat on the road, could not burst out at super high speed in the sea.

It was not impossible to forcibly inhale seawater and then heat it and spray it out, but some weak parts of the prosthesis might not be able to hold up, and in such a shallow sea, the noise would be too loud, which would easily attract the power of the protector.

Xiangshan chased for several hundred meters, and the dolphin fled farther and farther.

Xiangshan stopped in the sea, his mind was very complicated.

"Senior?" Yuan Wenren's signal came. The others were all sitting in the vehicle, and could only share what Xiangshan saw. And due to the bandwidth that the electromagnetic signal could carry, the quality of the picture they could see was limited.

They didn't see clearly what the big thing was.

Xiangshan said: "Something is wrong, absolutely wrong. Let's put other things aside... Let's follow the dolphin..."

"Senior?" Yuan Wenren was a little surprised, "Why did you suddenly change your mind?"

"It is impossible for dolphins to survive in a purely wild state." Xiangshan whispered, "Dolphins are marine mammals that breathe with lungs... Natural lungs cannot directly absorb oxygen from seawater..."

"Ah?"

"Under normal circumstances, it is difficult for standardized marine organisms to float." Xiangshan said: "Before standardization, the overall body density of many marine organisms that can swim will be slightly lower than that of seawater... These organisms also have corresponding organs to adjust this buoyancy to ensure that they can move in the vertical direction..."

"But after standardization, metal-based proteins will increase the overall density of organisms by several percentages, and terrestrial animals like humans will not be able to float at all. If the buoyancy organs of those marine organisms are still the original size, they will not be enough. I am afraid that only by swimming upwards with all their strength can they ensure that they are at a relatively shallow depth..."

It is precisely because of this that even if the ocean has rich biological resources, Yawgmoth does not think that many animals can survive the mass extinction.

"Not being able to float" is a fatal injury. For floating plants, this means sinking to the bottom of the sea where there is no sunlight. For animals, low temperature, high pressure, and lack of food are also fatal.

Unless there is human intervention to adjust the size of the cavity and the proportion of fat in the animals in advance.

Or, some large populations of marine organisms can rely on the stronger damage resistance after benchmarking to forcibly withstand the damage caused by the deeper ocean, and then spend more energy every day to swim upwards and desperately eat the artificially modified plankton in the shallow layer.

Perhaps three hundred years of virus-catalyzed mutations plus natural selection can preserve a little bit of small fish and shrimp... and squid.

But those marine artiodactyls are too difficult. These creatures need to do their best just to breathe.

In the original infection incident No. 1, those animal protectionists who tried their best to save whales also considered this. Yawgmoth adjusted the genes of whales to make it easier for benchmarked whales to accumulate lipids. At the same time, they also planned to provide buoyancy for whales through prosthetic swim bladders, or to lay artificial gill prostheses on the surface of whales. In addition, considering that whales have extremely high intelligence, they also considered teaching whales to "help each other". When the young whales are not strong enough, they will be carried to the surface of the water by adult whales that have undergone prosthetic transformation to breathe.

But this package plan should not be completed in the end. As the war burned into space at an incredible speed, the first generation of knights and the country-stealers left the earth. Yawgmoth also joined that war and rebelled at the end of that war.

This is an unfinished business.

Xiangshan also doesn't think that whales can really survive. Without human help, if whales rely on themselves, they will be at a loss even to breathe.

It is said that there will be "language" and "culture" differences between killer whales similar to primitive humans, but this may not be enough for them to survive that human disaster.

Moreover, there is no description of this in the documents of the Scientific Knights.

No one knows the existence of these things.

But...if...

Metal-based transformation will further increase the speed of nerve signal transmission and improve the thinking ability of organisms.

Perhaps humans are already smart enough, or perhaps most people cannot control such a powerful brain without training...

But for those organisms that have reached a certain critical point...

There is an emotion that drives him to check it out.

……………………………………………………………………

Hikasi swam quickly with half a squid in her mouth. The tongue of the marine creature flexibly retracted and rolled away the inner line of the mollusk in its mouth. The color change of the mollusk's skin is inexplicably regular, and it does not seem to be a simple dying reaction.

But Hikasi can't see clearly.

If we look at it by human standards, all dolphins are nearsighted. Dolphins understand this very well. They can hardly use the tools that humans use to measure distance, such as rulers.

But dolphins also have their own senses. In water, sound waves are much more convenient than light.

It's a pity that dolphins' senses really have no perception of "color changes".

Hikasi sucked the delicious juice in her mouth hard. She hadn't eaten for a long time. The existing fish are too small, and it is difficult for bottlenose dolphins to catch such small fish. And the resources are not enough. The dolphins are completely cyborgized and rely entirely on electricity to survive.

They have only made the most basic transformation, using an independent battery to replenish the energy of the central nervous system. This has relieved some pressure. But dolphins are not humans after all, and their bodies also need to be worshipped.

In recent decades, dolphins in distant places have discovered this new creature in the sea - humans call it "squid" and "squid". For hungry dolphins, this is a rare prey. It's a pity that this thing is too rare, and humans always persuade dolphins not to eat it to extinction, so dolphins have been suppressing their appetite.

But Hikasi is really hungry.

After eating half a squid, the torture from the stomach is clearer.

It's just that the mind is a little clearer.

Only then did Shikashi realize that before she lost her mind and rushed out, there seemed to be something next to the squid...

"Is it a human?" Shikashi thought: "From the shape, it is very different from the humans that have appeared before, it is very different..."

"But what if it is a human?"

"It's over, we must avoid the humans outside..."
