The thirteenth body chosen by Ye Ning was a salamander.

Salamanders are tailed amphibians that resemble lizards but have no scales on their bodies, and are good ornamental animals, including the northern newt, the salamander, and the great cryptogill salamander (a large aquatic salamander). They mostly inhabit freshwater and marshy areas, mainly temperate regions of the Northern Hemisphere. They rely on their skin to absorb moisture, so they need a humid living environment. When the environment reaches minus degrees Celsius, they go into hibernation.

The salamander is one of the most amazing animals in its ability to regenerate. Geckos can be regenerated with broken tails, octopuses can be regenerated with broken wrists, and salamanders are better, not only tails, limbs, but also some organs, eyes, and part of the brain can be regenerated, and the tissue regeneration process will not produce scars, almost perfectly replicate the parts before damage, in medical treatment, salamanders are regarded as a template for perfect regeneration, and it can be said that it has such a "holy grail" application as healing damaged spinal cord and brain injury.

When the salamander is injured in the body, the skin cells will quickly cover the wound, repair it within a few hours, do not need to form a thick scar like a human, a thin layer of skin cells will send a signal of self-defense, guide the nearby muscle cells, gather at the wound, and the regeneration process begins. The key to the miracle of regeneration is that the salamander's body cells can be reverted to the past, such as when a broken forelimb is broken, the cell will return to its embryonic state, and the biological program will restart and instruct it to grow the forelimb, and the nerves, muscles, and blood vessels will grow with the regenerated limb and re-establish the connection before the amputation.

Of course, the same salamander has different regenerative abilities of different species. Ye Ning chose a kind of salamander that is used in large numbers for regeneration research, the axolotl. Also known as the Mexican newt. Commonly known as the hexagonal dinosaur, this salamander is widely used in research experiments because of its outstanding regenerative ability.

In addition, the axolotl is a well-known "larval mature" species of amphibians (from birth to sexual maturity and egg laying, it is the form of a larvae), and the salamander has the strongest regeneration ability in the larval state, and the regeneration ability will gradually decrease as it grows into a mature body. In other words, newts that keep their larvae all the time are better able to maintain their best regenerative ability.

"The axolotl's ability element balloon is used on others, and I don't know how effective it will be."

Ye Ning made a newt become a clone yesterday, and spent a day cultivating to the early stage of qi training, awakening the ability, opening the beast palace, and becoming an evolved beast, the ability of the axolotl did not surprise Ye Ning's expectations, that is, the ability to regenerate, generally the limbs of the axolotl are cut off, and it takes two or three months to completely regenerate, and this morning Ye Ning experimented and cut off one of the left forelimbs of the axolotl. It took less than an hour for another intact left forelimb to grow. It is growing at a rate that is almost visible to the naked eye.

However, using the Ability Element Balloon on others, the regeneration speed is definitely not as fast as that of the axolotl itself, and Ye Ning is not sure what the effect will be at present.

Ye Ning controlled the regenerative element balloon of the axolotl, which emerged from the palm of his right hand, and then pressed on Liu Mao's broken arm, and in a moment the yuan balloon blended into it, obviously Ye Ning did not want to renew Liu Mao's arm, but let him regenerate his broken arm, the reason why Nangong Ya and others prepared the arm was just to make a show, I didn't want to be too shocking, and I continued to connect the arms of others to the injured, which was already amazing, not to mention the regeneration of the broken arm, it is estimated that it will shock the world in one day.

"Huh? How not long? ”

Ye Ning injected the regenerine balloon into Liu Mao's broken arm, and after three minutes, but there was no reaction, he immediately mobilized a small fox's perspective element balloon and integrated it into his eyes, and then looked through Liu Mao's broken arm, only to see that the vitality flow inside, the blood vessels, meridians, and cells of the arm were all affected, and a thin layer of skin cells appeared inside the suture of the arm, which stopped bleeding from the inside, and the muscle tissue seemed to begin to grow, but it was squeezed at the suture, so it could not move.

Ye Ning picked up a scalpel and quickly cut the suture at the broken arm, with the assistance of the perspective ability, the cutting was very accurate, revealing a layer of newly grown skin inside, of course, if there is no Regenital Balloon, no matter how precise the cut is, it is useless, once the cut is cut and sutured, the blood will not stop.

In fact, molecular genetic data show that the molecular mechanism of genetic regeneration of salamanders, we humans also have it, but unfortunately humans can't start it, for limb regeneration the world has been studied for many years, but now there is no substantial progress, if anyone completely overcomes this problem, it will absolutely shock the world, if the regeneration technology can be promoted, it will have a far-reaching impact on human beings, Winning the Nobel Prize is almost like a matter of provenance.

"It seems that one meta-balloon is not enough."

Ye Ning waited for an hour and a half, Liu Mao's broken arm had grown twelve or thirteen centimeters, originally only to the elbow, and now he had a small arm, but through perspective, he saw that the Yuan balloon was almost exhausted, and in desperation, Ye Ning could only consume two hundred points of Yuan Qi, injected it into the body of the American axolot, quickly condensed a Yuan balloon, and then mobilized it. This continuous mobilization of the Yuan Balloon will bring a great burden to the animal clone, and it will take a week or two to recover, affecting growth.

However, in order to let Liu Mao grow an arm at one time, he can only sacrifice the axolotl, otherwise it will be strange for others to see Liu Mao's half-amputated arm, and there will be no way to use the continuation of the arm as a cover.

The second Yuan balloon was injected into Liu Mao's broken arm, and the growth of the broken arm accelerated slightly, and after waiting for more than two hours, it finally grew completely.

Looking at Liu Mao's left arm, which was intact and even had no scar at all, Ye Ning himself was amazed and excited, which meant that even if he broke his hands and feet due to some accident in the future, he would be able to grow it back, and even if he practiced the Sunflower Book from the palace with a knife, he could grow it again, this ability was simply against the sky.

"No, it's perfect."

In order to be more authentic and credible, Ye Ning used a scalpel to cut a circle of cracks on the severed part of Liu Mao's original arm, and then sutured the skin with needles and threads, so that it looked as if an arm was connected, and then Ye Ning used gauze to bandage Liu Mao's left arm tightly.

After all this, Ye Ning opened the door of the ward and walked out.

"Doctor Ye, was the operation successful?"

Nangong Ya, the bearded man, the charming woman, and Zhu Lixing and many other doctors surrounded them one after another.

Even, Kong Huasheng, Tao Wan and a few interns heard the movement and walked from the other side of the corridor, obviously Ye Ning's operation had already been concerned by the whole hospital. (To be continued......)
