Robin's speculation sounds a bit shocking, but if you look closely at the composition of the human body, then there is some theoretical basis for his speculation.

Just like the mitochondria, the body's powerhouse, mitochondria were nothing more than bacteria parasitic in the human body in the beginning. Through continuous evolution, this bacterium lost its original reading power and became completely dependent on the human body, and evolved into the master of life today. And the accidental product of the source cell is now the evolutionary path of replicating mitochondria in Robin's body.

Through the study of his own cells, Robin found that the role of mitochondria in his own body is completely different from that of mitochondria in normal cells.

Under normal circumstances, the mitochondria in the cell are all the energy that the cell relies on to survive by oxidizing organic matter. And its existence makes the element oxygen very important in human physiology.

But now in Robin's body, due to the source cell, the cells that divide through the source cell have undergone a fundamental change in energy production, and the most significant point of this change is that the effect of oxygen has been greatly weakened in Robin's body.

Oxygen has always played a key role in the evolution of human beings and life species on Earth as a whole. And breathing oxygen has even become the instinct of human beings, no one will feel that oxygen is toxic, and no one will think that oxygen is harmful, so most people do not know that the aging of the human body and the failure of various organs is actually the process of oxidation of the human body, in a sense, human beings are actually committing suicide by breathing oxygen.

This so-called theory of oxygen toxicity was mentioned by Robin as early as Pluto's time. At the time, he didn't understand the true meaning of this theory, but now, as he became more and more knowledgeable in biology, he began to understand the true meaning of the theory that oxygen was toxic.

That's right, from the perspective of aging, human beings breathing oxygen are indeed slow to commit suicide. But if you don't breathe oxygen for fear of aging, then you will immediately commit suicide. Therefore, as human beings living on earth, there is actually no other choice on this issue.

However, the absence of a choice does not mean that humanity has given up on the struggle.

As a life on earth, human beings have continued to grow in lifespan over millions of years of evolution, and the reason for the exponential increase in lifespan is not only the reduction of survival pressure, but also the greater reason is that human beings have begun to use hydrogen as an element to fight against the body's oxidation reaction in the process of evolution.

According to the conclusions reached by the research of scholars in the new era, the human body contains a large amount of hydrogen, and hydrogen participates in the energy metabolism of the human body, which is the energy substance of life. In addition, hydrogen also has great effects on antioxidation, anti-aging, and scavenging free radicals, which are harmful compounds produced by mitochondria in oxidation reactions, and have strong oxidative properties, which can damage body tissues and cells. Therefore, the aging and disease of the human body are largely due to the formation of excessive free radicals accumulated in the body.

In the Earth's environment, hydrogen does not stay near the earth's surface like oxygen because it is lighter and oxygen is heavier. Therefore, human beings are evolutionarily limited by innate conditions and cannot get rid of their dependence on oxygen.

But now, after entering the space environment, the universe contains a large amount of hydrogen, but oxygen has become a rare element, so the change of the general environment makes it necessary for human beings to evolve rapidly in order to get rid of the influence of the earth on the remnants of species, and quickly adapt to the new environment of the universe.

In this regard, Robin, who underwent a second genetic mutation and possessed the source cell, became the first person in the human race.

At present, although he does not know that he has become a pioneer in the new humans, he has already noticed that he is different from ordinary people.

As he came to by studying his own cells, although he absorbs oxygen through respiration like other humans, in addition to absorbing oxygen, his ability to absorb and store hydrogen is also very different.

Moreover, although the mitochondria in his cells still generate energy by oxidizing organic matter, the energy generated by the mitochondria is not directly applied to the human body, but is a second energy generation in the cell.

According to his research, he discovered that the second energy production in his cells was exactly what hydrogen was at work.

Relying on the far more hydrogen in his body than ordinary people, Robin's cells use the energy generated by mitochondria to push the hydrogen stored in the cells, and generate a larger amount of energy through a cold nuclear fusion reaction, and quickly digest the free radicals generated by the mitochondria during the nuclear fusion reaction.

Performing a nuclear fusion reaction in the human body sounds even more incredible than a myth. However, nuclear fusion not only produces more energy than nuclear fission, which is formed by splitting heavy atoms, but also releases far less radiation pollution than nuclear fission.

However, the cold nuclear fusion that takes place in Robin cells is not the thermonuclear fusion that is normally produced by thermonuclear reactions.

Thermonuclear fusion is a nuclear reaction formed by fusing several light nuclei into one heavier nucleus at an ultra-high temperature at which the reaction conditions are reached. At the moment of fusion of atomic nuclei, a huge amount of energy will be generated explosively.

Cold nuclear fusion, on the other hand, does not need to meet the requirements for the formation of thermonuclear reactions. Cold fusion is a type of nuclear fusion that takes place at room temperature and is fueled by human bioenergy. Compared to thermonuclear reactions, which generate explosive energy, cold nuclear fusion is much slower, and the energy generated is far less massive than that of thermonuclear reactions. However, compared with human beings, the energy generated by cold nuclear fusion is far greater than the ATP produced by mitochondria, and the free radicals with strong oxidation are digested during the nuclear reaction, which indirectly protects the body's tissues and cells.

After reaching this conclusion through self-exploration and research, Robin's shock can be imagined. Because his energy generation method is more advanced and complex than others, and this change means that he has completely integrated nuclear energy into his body, becoming one of his most important life instincts.

Although the immediate effects of this slow generation of nuclear energy are far from being compared with those before the second mutation, at the current rate of cold nuclear fusion reactions, it may take years to accumulate nuclear energy in the body to reach the huge base before the second mutation. But the huge nuclear energy accumulated in the body before is only an external force after all, it is not the energy naturally generated in Robin's body, so in practical use, Robin must rely on the 'subtlety' to complete, and the low utilization efficiency makes most of the nuclear energy wasted in the process of use, and only a small part is actually used.

However, now it is different, although the total amount of nuclear energy accumulated in the body is not even as good as one ten-millionth of the past, but because this small amount of nuclear energy is naturally generated by cells, Robin can achieve 100% utilization efficiency, and no longer need to rely on the help of 'subtlety' in the way of use, but the distribution and release of nuclear energy by the body's instinct. Therefore, although the current Robin does not have the explosive peak combat power of the past, he has greatly improved his average combat power and growth surname. Moreover, the bottleneck of Robin's power that had been limited in the past no longer existed due to the change in the way of energy generation.

In the past, with Robin's physical talent, the upper limit of his strength could only reach the third order, although after storing radiation energy in his body, Robin was able to temporarily burst out beyond the fifth order of power, but after all, this was at the cost of harming the body, so the short-term fifth-order power could only be regarded as borrowing, not Robin's real strength.

The real reason for Robin's strength bottleneck is actually because of the scarcity of mitochondria in muscle fibers and the scarcity of mitochondria in muscle cells, which directly leads to Robin's muscles being unable to further improve their strength due to insufficient energy supply.

Now, although the number of mitochondria in Robin's muscle fibers has not increased, because the energy supply mode has been changed to cold nuclear fusion in cells, the nuclear energy produced is far greater than the bioenergy generated by mitochondria alone, so there is no shortage of energy supply in muscles. This allows Robin to solve the bottleneck of strength, and only through regular exercise, can increase his strength normally.

In addition to the full development of the growth potential of strength, brain cells with a large number of mitochondria also have the potential to be redeveloped due to the change in energy production, which allows Robin to develop the potential of the body while further exploring the potential of the brain domain, as evidenced by the breakthrough of second-order perception after the second genetic mutation.

Through the study of biology, Robin's understanding of his own body has been more than ever, compared to the previous self-exploration in ignorance, Robin can even make detailed plans for his own growth, and the foggy future in the past has become clearer and clearer in Robin's eyes.

Perhaps because he is experiencing more and more of the benefits of knowledge, Robin, who hated theory classes as a student, has now become a bookworm. On the TR-735, he was also more of an academic than a Marine Corps commander. Gradually, some of the new Marines even began to jokingly refer to Robin as the 'Infantry Professor'.

"Report sir! ～”

Just as Robin was snuggling up in his cabin as usual to study the newly released biology report from the Republic's sources, Andrew suddenly came to report.

Robin returned a military salute without raising his head, and casually asked, "What's the matter?" ”

"That Christine has been making trouble for a long time, and she has to look for you, saying that she has important information to convey to you." Seeing that he had disturbed Robin, Andrew said with some embarrassment.

"Christine?" Robin raised his head when he heard this, and showed a wry smile helplessly.

This Christine is the youngest of the stowaways captured by Robin in the IS9132 celestial body, originally he always thought that this Christine was bewitched by other people to choose to smuggle, but he didn't expect this kid to be the initiator, and during the time he was captured, this kid changed his way to intercede with Robin, and begged Robin to give him a chance to mend his ways.

Andrew obviously knew this, and seeing the wry smile on Robin's face, the honest Andrew immediately said in shame: "Otherwise...... I said to him, you don't have time to see him? ”

"No, I'd better go." Robin put away the electronic notes and said with a playful smile, "I want to hear what he can say to impress me this time." ”
