Victor and James' self-healing abilities are incomparably strong, not only are their skin, muscles, and bones perfectly "regenerated" and repaired after being "destroyed", and then strengthened, without leaving any scars, but also their self-healing abilities work on all tissues and organs throughout the body.

Including the heart and brain!

The heart is the driving force of human blood circulation, when the heart is damaged and stops beating, and loses the ability to pump blood, the blood in the human body will stop flowing, and all the cells in the body will also lose the energy and oxygen supplied by fresh blood, and will soon die.

The brain has the greatest need for oxygen, and brain cells die the fastest when the heart stops beating.

When the heart stops beating for 10-20 seconds, consciousness disorders will occur, syncope, convulsions, coma, brain cells begin to die in about 60 seconds, and when the heart stops beating for 6 minutes, all brain cells will die, and within 10 minutes, other organs and cells such as muscles and internal organs of the body will gradually die, and the whole body will completely lose its vitality.

Because Victor and James' current self-healing ability awakening time is still short, they have not yet reached the strongest state, the repair speed of body cells is slow, and it takes more than ten minutes for the injury to be completely repaired, and it is impossible to repair the broken heart and restore the energy and oxygen supply of fresh blood before the body cells completely die, so before the repair of the heart is completed, the person is already dead, and the repair is interrupted, and he cannot come back to life.

And if the self-healing ability of the two is enhanced and repaired quickly enough, they can recover from all the injuries before the cells die, even if the heart is completely destroyed or even dug out, the self-healing ability can also recreate a new heart before the brain dies, maintaining the supply of energy and oxygen to the cells of the whole body, and will not die because of this.

When the repair is fast enough to be completed in a matter of seconds, even the brain will not feel dizzy due to lack of oxygen, let alone coma.

However, if the brain is directly damaged, it is another matter.

Ordinary people will die if their brains are damaged, but the cells in Victor and James' bodies are self-healing, including brain cells, so their brains can still repair themselves after being damaged.

However, the beating of the heart is controlled by brain cells, and if the brain is destroyed, the heart will stop beating instantly, and with the current repair ability of the two people, they cannot complete the repair before the death of the cells in the whole body.

Therefore, the brain and heart are still harmful to the current Victor and James, and if they are damaged, they are still a dead end.

In addition, when the brain is damaged or brain cells die and are repaired, the brain can be restored, but the memory cannot be restored.

In the movie, Wolverine was shot into the brain by an Edelman metal bullet, although he did not really die with his strong self-healing ability, but was resurrected again after repairing the brain with his self-healing ability, but all the previous memories were gone.

Despite this, the two people with this strong self-healing ability can also be regarded as immortal.

Moreover, based on Chen Mo's observation of the physical condition of the two people during this time, as well as his understanding of his own body, he found that these people with special abilities, after their physical fitness is strong enough, the ability of body cells to endure hunger and lack of oxygen will also be enhanced, and after the heart stops beating, they can survive longer than ordinary people, which also retains enough repair time for the body, even if the body suffers devastating damage, the heart stops, breathing stops, and it looks completely dead, but the body cells are actually still alive. And continue to repair the body and still be able to come back to life.

That is to say, with the enhancement of Victor and James' self-healing ability and the improvement of their physical fitness, the repair speed of the body is getting faster and faster, and the cells can survive longer and longer after the heart stops, and when the time comes, it will become more and more difficult to kill them, and if the ability of the two of them continues to improve indefinitely, they can even reach a legendary limit state.

If the self-healing ability is strong enough and the cells in the body are strong enough, even if there is only one cell left, it can still be repaired and regenerated and resurrected again!

Of course, this situation is only a limit of possibility, and it is actually very difficult to achieve.

These are all things for the future, and now, Victor and James are not the two ferocious beasts that are almost immortal in the future, the real saber-toothed tiger and Wolverine, but just two young beasts with a certain ability to heal themselves, but they will still die when their hearts and brains are attacked, and their abilities still have a lot of room for improvement.

Chen Mo has long discovered that with their self-healing ability far beyond ordinary people, Victor and James' physical fitness has improved far beyond ordinary people in the process of "destruction, regeneration, and enhancement" through continuous fighting, and they do not need to control the limit of "destruction" when practicing martial arts or fitness and exercising like ordinary people, so as to avoid injuries and permanent damage to the body.

As long as the heart and brain are not damaged, the more serious the injuries suffered by the two in the battle, the greater the improvement of physical fitness, and the self-healing ability of the two is also continuously enhanced with the improvement of physical fitness, between self-healing ability and physical fitness, a perfect relationship has been formed to promote each other and improve together, as long as the two continue to fight, continue to be injured, self-healing, physical fitness and self-healing ability will continue to improve.

And this is in line with their belligerent wildness, which shows that they themselves have the instinct to become stronger through battle, and in the movie, after the two left the Howlett Manor, they participated in the American Civil War, World War I, World War II, and the Vietnam War, which shows that their belligerent nature runs throughout, and has always pushed them to participate in battles and improve themselves.

In fact, after so many years of fighting, the two do have very strong strength and self-healing ability, even if they are continuously fired by a rifle, they will not die, the wound can heal quickly in a few seconds, even if they are pierced in the heart, they can still continue to fight, and their brains can be resurrected again after being beaten into a pulp by bullets.

What Chen Mo has to do now is to advance this kind of enhancement and consciously provide them with more fighting opportunities, so that they can hone their fighting skills in battle while constantly strengthening their physical fitness and self-healing ability.

This time, the fur purchasing team of the Lakota tribe found traces of the armed personnel of the American Fur Company, which meant that Victor and James had another chance to fight, and the two were naturally excited, but this time Chen Mo did not go with them.
