Perhaps because of the amount of mental power consumed before, Kakashi was in a coma for the next three days, and although he slept peacefully, he never woke up.

And Ling Yun injected him with life force again every few hours during these three days, preventing his body from deteriorating again.

It wasn't until three days later that Tsunade and Lingyun were all ready, and the treatment officially began.

At this moment, Kakashi was naked, starting from the position of his heart, and his body was covered with strings of special runes, densely packed, looking very mysterious and weird. Speaking of which, it is somewhat similar in appearance to the evil sealing seal used by Kakashi when he sealed Sasuke's curse seal in the original book.

Among them, there were nine runes extending from his body to the four sides, leading to nine different positions around him, and the strength of each rune was the same as the half-opened sealing scroll, and the part of each scroll that was opened was written with a big "source" character, which was neat and tidy.

And Ling Yun himself, sitting on the top of Kakashi's head, had dozens of complicated handprints with a serious expression, and then, a pale green chakra emerged from his palm, and with Ling Yun's point, it slowly crossed into his body from the Baihui acupoint on the top of Kakashi's head.

"It's time to go." With the passage of Yuan Dun's energy, Ling Yun suddenly spoke, and said to Tsunade, who had been waiting on the other side.

Hearing this, Tsunade immediately stepped forward and stabbed a potion that had been prepared earlier into the veins of Kakashi's arm, and the potion was slowly injected into Kakashi's body, flowing all over his body along with his blood. Then, Tsunade pulled out the needle again, quickly exited the range of the rune, and began to prepare another potion.

Seeing that Tsunade had finished inputting the "Gene Melting Elixir", Ling Yun immediately sped up the speed of chakra delivery and completely activated all the runes he had carved before.

The runes carved on Kakashi's body, extending to the bed, and on the floor, all bloomed with turquoise light after being activated by the Lingyun Chakra, like small glowing tadpoles, surging towards the center of the rune at Kakashi's heart, and then burrowing into Kakashi's body.

As the runes with the energy of the source escaped burrowed into Kakashi's body, new runes flowed out of the nine scrolls with the word "source" written on them on the other side, and continued to line up in a neat queue, surging towards Kakashi.

After half an hour, the word "source" in the nine scrolls slowly faded, and all the runes also drilled into his body from the center of the rune at Kakashi's heart, and finally disappeared completely.

On the other hand, on the medical detector, Kakashi's various data have also reached unprecedented highs. Whether it's Kakashi's vitality strength at this moment, cell activity, or some other data such as heartbeat and pulse, this moment couldn't be better, more powerful. It's so strong that it doesn't seem to be a person anymore, but some kind of more high-end lifeform!

The medical ninja who was in charge of monitoring Kakashi's various body data had already completely dropped his jaw, and he was secretly speechless one by one.

This is the power of Lord Lingyun! Not only can you defeat all strong enemies without fear, but you can also turn a person whose body is about to collapse into a monster whose body data is so strong that all your body data is a mess.

Is this still something that people can do? Or, did Konoha really have a second ninja god?

Ignoring the shock of those medical ninjas, Liang Yun had already withdrawn his right hand that was on the top of Kakashi's head at the Baihui acupoint, and then suddenly sealed again, immediately triggering the mechanism that was originally placed on the bed. Straps bounced off the secret spot on the bed and buckled on the other side, and in a matter of moments, Kakashi was completely wrapped in knots, as if he had become a large rice dumpling.

After doing all this, Ling Yun raised his head again, turned his head to look at Tsunade, and nodded seriously.

Seeing this, Tsunade's pretty face was full of seriousness. Slowly taking out the syringe that had been prepared in the morning, he walked quickly to Kakashi's bedside, took a deep breath, and then began to use his hands to inject the liquid into Kakashi's vein.

This needle is injected into the first generation of cells!

With the infusion of the first generation of cells, Kakashi's expression gradually changed, from the initial calm, gradually became distorted, from the slight frown at the beginning, revealing a slight pain, and after a while, it became extremely hideous, obviously this pain was almost beyond his limit.

After another moment, Kakashi's body finally couldn't help but start struggling subconsciously. But under the constraints of dozens of belts, his struggle was doomed to be futile. Under such constraints, he couldn't break free at all, and naturally he couldn't hurt himself.

Only his bulging muscles and twisting form proved how violent his struggle was.

After another moment, due to the friction between his body and the belt, clear blood marks had appeared on Kakashi's body, and bright red blood slowly oozed from it, staining the white sheets into a little blood red.

I don't know if this blood is Kakashi's redness?

Strange thoughts popped up in Ling Yun's mind, fleeting. Then, Ling Yun's attention was once again focused on Kakashi's physical changes. The rejection seemed to be getting worse and worse, and Kakashi's struggle became more and more intense, knowing that it took three hours for the rejection to gradually subside under the effect of the "gene fusion drug".

Next, Kakashi will face another difficulty, and that is the mutual devouring problem that will inevitably arise in the fusion of genes.

Tsunade and Lingyun, who were Kakashi's attending physicians, knew very well in their hearts that the seemingly peaceful situation was the most dangerous stage. The previous rejection was terrible, but they had already prepared for it, and it can be said that they were absolutely sure that Kakashi would get through that most difficult period.

And the current situation, it is no wonder that he can successfully get through the current situation, but it can only depend on Kakashi's own will, which can withstand the devouring of the willpower in the first generation of cells.

What Ling Yun can do is to inject some life force into his body every once in a while to maintain the activity of his own cells, and it will not decay due to the mutual devouring of genes.

And so, it took another three days for Kakashi's body to stabilize this time. Especially the blood marks and wounds on his body that had been rubbed out during the previous struggle began to heal at a speed that was visible like smoke, and they recovered as before, and Ling Yun and Tsunade were truly relieved.

Because of Kakashi's gene fusion treatment, it finally succeeded!
