Between exhalation and inhalation, the waste products of metabolism in the body are eliminated, and a large amount of fresh air swells into the body.

"Evolution."

Qi Fei had been sitting on the roof of the Howling Wind Mansion for a long time, and the sandalwood around him was overflowing, but he still couldn't make him feel at ease.

The speed is not enough, the bones are too soft, and the biocomputer resources are insufficient. A large number of defects are in front of you, making it impossible to break through.

After analyzing it for several days, in fact, there is no need for strong bones to a large extent, but there are too many deficiencies in speed and explosiveness.

Therefore, Qi Fei was holding a flea in front of him, and he was now pondering whether to ingest the flea's genes.

"The fountain of immortality in the body can still be used once, and after using it once, if you want to evolve again, you have to continue to contact with Tianjiao."

In the midst of gains and losses, a tentacle appeared on Qi Fei's body and gently wrapped the glass container. With a slight force, the glass container was unscrewed, and the little flea felt freedom and quickly jumped towards Qi Fei's body.

As everyone knows, as soon as its feet touch Qi Fei's skin, it is controlled by the viscous cytoplasm on the surface of the skin.

At the same time, Qi Fei's nucleus began to stir, and a large amount of mysterious substances entered the vicinity of the nucleus, beginning to awaken the primitive instinct inside the nucleus.

The chromosomes began to stretch, and a breath from the wilderness burst out from Qi Fei's body.

Qi Fei's thoughts moved, and the aura from the top of the food chain suddenly converged. The little flea struggled in the cytoplasm, jumping, flipping, and finally touching various enzymes.

In less than the blink of an eye, a small creature has been split into large and small cell structures.

The messengers in the body began to intertwine, the Golgi apparatus began to wriggle, and the mitochondria burned wildly. The cell membrane of flea cells is broken down, revealing the contents inside.

Little by little, Qi Fei ingested every bit of possible information.

Fragments of genes are suspended in the cytoplasm, and the four bases of ATCG are paired rapidly with mysterious rules.

The electromagnetic force is the pivot that runs through the structure of every cell.

Reorganize, change, evolve.

Qi Fei is like a dry sponge, constantly ingesting the nutrients in it.

In nature, people are greatly surprised when they find that a flea with a body length of no more than 2 millimeters can jump to 150 times its length, that is, about 30 centimeters, which is comparable to the height of a person who is 1,000 times its length. In addition to being surprised, people called it magical, and gave the honor of the high jump champion in the animal kingdom to its unsightly flea.

Based on a false intuition, people think that if a person somehow gets the bounce mechanism of a flea, it will jump up to 150 times the length of his body, which is nearly 300 meters!

Scientists who are curious about fleas have found that the biggest difference between fleas and humans in the bounce mechanism is a highly elastic substance called "elastin" on fleas. This elastin is in the abdomen of fleas. When the flea is bouncing, it first tightens its thighs and compresses the mass of elastin, and then when the legs are loosened, the elastin releases energy in an instant and bounces the fleas into the air. People then fantasized that if elastin was added to a person's leg through some kind of genetic engineering, wouldn't a person's jumping ability increase hundreds of times?

The ruthless laws of physics lock even those who have added elastin to the ground. What's even more ruthless is that people who add elastin, in addition to paying a significant price, may not be as high as normal people. Many insects, including fleas, use elastin in their bouncing mechanism because they are so small that they can't jump at all without using elastin; The function of elastin is not to make them jump high, but only to make them jump. The use of elastin in order to be able to jump is like drinking a donkey to quench thirst, and the price to pay is to withstand the gravitational force of tens or even hundreds of times the acceleration of gravity when taking off, and to spend extra effort to overcome air resistance due to the fast acceleration.

Elastin. In order to reach a bounce distance of tens of centimeters to avoid predators or change hosts, insects must reach a certain take-off speed. The time to reach this take-off speed (acceleration time) is directly proportional to the acceleration distance of the thigh and inversely proportional to the take-off speed. Roughly calculated, the acceleration distance of the flea's thigh is about 0.75 mm, and the acceleration time is less than 1 millisecond in order to reach a height of tens of centimeters. The locust's thigh is about 4 centimeters long, and the acceleration time is a few milliseconds. The fastest action time of animal muscles is also about 50 milliseconds, which is much slower than the acceleration time required by fleas and locusts. In order to solve this problem, elastin was naturally discovered, and its action time is 0.7 milliseconds, which is exactly what insects require.

Humans and other mammals, because the scale is much larger than that of insects, the take-off acceleration time is generally a few hundred milliseconds, slower than muscle, and muscle is enough to meet the requirements, so elastin is not needed. There's a reason why elastin is only found in insects and not in mammals.

Elastin cannot produce as much energy as muscles, but can only store energy and release energy very quickly, and its energy is ultimately generated by muscles. The reason why insects use it is to trade time for space (very small body, very small acceleration distance). The price of using it is the force generated by the instantaneous release of energy. When a flea jumps, it has to withstand 245 times the force of gravity; 15 times for locusts; The number of kowtowers is 382 times, which is a world record. When a person takes off, he only needs to bear 1.5 times the force of gravity, which is much less than 10 times that a person can bear. Insects take off with so much force because they have no choice. If we think it's a magical way to bounce, with elastin on a human leg and jumping as fast as a flea, then it's fast, and it's a meatloaf that rises into the air.

Evolution represents new dangers, as well as the possibility of touching entirely new territories. And Qi Fei was controlling his body at this time, changing step by step towards the impossible.

He did not use the cellular structure of animals and plants, but used special body fingers to slowly weave a special network of flea bounce protein, and then used a very ingenious way to weave flea elastin and ant muscle protein, and then used human muscle protein as an embellishment.

The proteins of three different organisms are becoming more and more obvious under Qi Fei's ingenious ideas. The chromosomes in the body are becoming more and more stable after receiving new gene fragments.

When Qi Fei opened his eyes again, intense hunger filled every corner of his body. Just trying to pull his body, a huge force vented on the marble floor, leaving a groove.

At the same time, the bones covered with a layer of foamy chitin were able to withstand the explosion.
