Ji Zhi immediately understood that Ling Bing should be treating Feng Tian's injuries, and his eyes suddenly lit up. Especially when he saw the thin layer of black oil covering Feng Tianfang's skin, he was even more energetic.

He understood at a glance that these black oily substances were impurities in the body.

Although he had never seen marrow washing, Ji Zhi, who was born as a biochemical expert, knew very well that the human body was not pure, and there were all kinds of harmful things deposited. This is also the reason why human beings slowly age and die.

In fact, in the eyes of modern technology, all cells in the human body have a limited lifespan, and their lifespan will automatically die in the human body. But the human body will automatically produce new cells to replace the dead cells, so people will live.

Children will grow up and become stronger and stronger, because the new cells in the child's body are always greater than the dead cells; but when the child grows into an adult, the number of new cells and dead cells will basically be maintained at a relatively balanced level; when the adult is getting older and older, the new cells in the body begin to slowly be smaller than the dead cells, then human beings will appear to be aging; when the new cells are less than a certain amount, human beings are piled up in the body by most of the dead cells, and this is the time when human beings are slowly moving towards death.

The reason why the new cells in the human body are slowly smaller than the dead cells is because there are too many dead cell corpses in the human body, which cannot be discharged in time, "polluting" the general environment in the human body, so there are fewer and fewer new cells.

In fact, the reason why those awakened people live much longer than ordinary people is because the new cells in the bodies of those awakened people are updated very quickly, much faster than ordinary people, and the lifespan of cells is also longer than that of ordinary people. In addition, after each promotion, the huge energy brought by the promotion will force those dead cell residues deposited in the body to be excreted from the body. He himself was like this, when he was promoted to the eighth rank, such a thin layer of black oil appeared on the surface of his body. Therefore, the more high-level Awakened people are, the younger they look, and the longer their lifespan will be.

According to this theory, Ji Zhi also imagined that if one day, human science and technology developed to the extent that they could regularly clean the environment inside their cells, so that the new cells would always maintain a relatively balanced state with the dead cells, then would human beings be able to theoretically achieve immortality and immortality? Even ordinary people can live forever?

But after all, he has not been able to find an effective and feasible way to clean up the garbage in the human body. It is best to clean up the impurities in the blood, which is now possible with technology. However, cleaning the environment in the human body is not only to clean the blood, but also to clean the flesh, bones, and brain, which is not what current technology can do.

But now Jiujiu has actually done it, and she is actually "washing" Feng Tianfang's body. Those greasy black oily substances should be dead cells and various harmful deposits that have been cleaned up from the human body.

Ji Zhi couldn't help clenching his fists, and his breathing became a little short of breath with excitement.

How did she do it? How many secrets does she have?

Ji Zhi couldn't help but wonder, is Jiujiu still a Blue Star person?

It's a pity that Ling Bing didn't know what Ji Zhi was thinking now. If Ling Bing knew, he would probably reply to him, "Child, you are the truth!", and then kill people or something.

Ji Zhi was standing at the door so firmly, reluctant to move his steps, he wanted to witness with his own eyes what the result of Hua Jiujiu's cleanup this time was. After Feng Tianfang cleaned up this time, what was the difference between him and before.

Mu Yu was very strange, why did he speak so well, Ji Zhi suddenly jumped up and rushed to the location of the mobile folding room where Feng Tianfang was. But when I got to the door, I kept standing and didn't go in, what happened?

He didn't feel that he followed quickly, and looked into the room from behind Ji Zhi.

However, as soon as I arrived at the door, an unusually fishy smell rushed to my nose.

What's it? Why does it stink so much? ......

Mu Yu couldn't help but think of the worst-case scenario, well, Feng Tianfang's injury is too serious, is it incontinent?

But when Muyu thought about it carefully, he felt that it was wrong. It didn't smell like the thing, but like the smell of an animal carcass when it decomposed.

Suddenly, another scenario occurred to him.

Advance!

Mu Yu suddenly thought that when he was promoted to the eighth order, the smell coming from his body seemed to be like this. Could it be that Feng Tian put it on the promotion level?

But how is this possible?

Feng Tianfang's injuries were so serious, the bones on his body were almost broken, and he was still in a semi-coma, in this case, how could he be promoted?

"Your Excellency Ji Zhi?"

Muyu gently pushed Ji Zhi, who was in a trance, a little shocked by the light in Ji Zhi's eyes, which was so hot that it was so bright that people didn't feel it looking directly.

was pushed by the wooden fish, Ji Zhi was startled, and his reason finally returned.

The person in this is Hua Jiujiu, the object he swore to follow, even if she has more secrets, it is the object that he must do his best to protect. What's more, all kinds of signs show that Hua Jiujiu is very likely to be the hope that their Ji family has been waiting for for thousands of years, how can he have the desire to dissect Hua Jiujiu and uncover all her secrets?

"Huh~?

Ji Zhi's head immediately calmed down, turned his head, looked at Muyu, and said softly.

"What's going on inside? Is Major Feng being promoted?"

A light flashed in Ji Zhi's eyes, and there was an inexplicable taste in his voice: "No, he is not in the promotion, but it is not much different from the benefits brought by the promotion." ”

Muyu was stunned.

It's not in the promotion, but it has the effect of promotion, what does this mean? What are the benefits of promotion? It should be more powerful and longer, right? Is this what Feng Tianfang is like now? What is the situation?

In the room, Ling Bing was sweating profusely, and his entire clothes were completely soaked with sweat and clinging tightly to his body. The small jade bottle next to the Peiqi Pill has been empty, and the small jade bottle where the Rejuvenation Pill is placed has also been empty, and now the entire marrow cleansing has reached the final stage.

At this time, Feng Tianfang's muffled snort was rarely heard. The effect of washing the marrow has been well reflected in his body, and the impurities in the skin, tendons, bones, and marrow have been forcibly discharged from the pores of various parts of the body under the cleaning of Ling Bing's chaotic spiritual power. Feng Tianfang suddenly felt that the pain that was enough to make people crazy had become not so unbearable. Even after the pain in various parts of his body, there was a feeling of relaxation and dripping, which made him feel a sense of pain and happiness, and even looked forward to this pain to last a little longer.

He could feel the strength in his body slowly returning, stronger than before the injury. No matter how stupid he was, he knew that Hua Jiujiu's previous remark that "surviving this pain will be of great benefit to his future cultivation" was not lying to him. He could already feel the ease in his body, and he could also feel that the speed at which martial energy flowed through his body was obviously accelerating. The sluggish feeling when he used to run the martial arts had long since disappeared, and he could have a hunch that if he cultivated again, the effect would be several times that before he was injured.

"Uh-huh~"

"Poof~~"

Suddenly, two spitting sounds came out at the same time, and Feng Tianfang and Ling Bing both vomited out mouthfuls of blood at the same time. The only difference was that Feng Tianfang spit out completely black blood full of fishy smell, while Ling Bing spewed out completely bright red blood with a strange fragrance.

After the blood spit out, the reactions of the two were also completely different, and after Feng Tianfang spit out a mouthful of blood, he actually jumped up. After Ling Bing spat out a mouthful of blood, his body fell limply to the ground.
