After leaving Tsunade and Shizune.

Yu came to the room inside the Konoha Ninja Hospital and slammed the door shut.

Walking into the room, he was greeted by all kinds of sophisticated medical equipment and instruments around him, as well as instruments and equipment similar to computers.

"It's been a long time since I've been here......"

"Looks like nothing has changed here......

Seeing that the placement of these medical instruments and equipment in front of him hadn't changed much compared to before he left Konoha, Yu breathed a sigh of relief.

Open the air!!

As he spoke, Yu opened the door of the Realm King's Alternate Space and took out four transparent glass test tubes from each of them.

One of them is the wood escape cell between the first Hokage Thousand Hands Pillar collected from him when he tortured Danzo before, and the other three are blood samples from the three of Uchiha Sasuke, Uzumaki Kari, and Kaguya-kun Maro.

"First of all, extract the genes first......"

Although extracting genes from cells and blood samples is a technical task, it is not difficult for Yu to use medical knowledge to operate these sophisticated medical equipment and instruments as the captain of Konoha medical class.

"Alright, the extraction is complete......"

It took half an hour and after some professional manipulation, Yu finally extracted the genes from the blood samples of the three of them, including the Mu Dun cells between the Thousand Hands Pillar, as well as the Uchiha Sasuke, Uzumaki Karyo, and Kaguya-kun Maro.

Carefully comparing the genes of the four under the instrument, Yu really found that the genetic chains of Ni Duan-Uchiha Sasuke, Uzumaki Xianglin and Thousand Hands Pillar not only coincided with each other, but also had a complementary tendency.

But Kaguya-kun Maro's gene chain is very strange, and it actually matches some of the previous three people's gene chains, but not all of them.

"As I expected, is that really the case......"

After looking at the comparison of genes in his hands, Yu couldn't help but mumble to himself in a little distraction.

Sure enough, just like his original diagnosis, Jun Malu's blood inheritance disease was caused by the incomplete gene chain and partial mutilation, and there was no problem in the usual situation, but the more frequently he used his blood inheritance limit, the corpse bone vein, the more serious the disease would be.

To put it bluntly, it is a genetic disease that is passed on to one's next generation through blood relations!

In the setting of the Hokage world, every ninja has the opportunity to awaken and obtain an atavistic phenomenon and ability, for example, the people of the Uchiha clan have the opportunity to awaken the ability of the Sharingan, the ancestor Indra, and the people of the Thousand Hands clan and the Uzumaki clan have the opportunity to awaken the body of the immortals, the ability of the ancestor Asura.

This is exactly the case with Jun Ma Lu, the Kaguya clan is the bloodline handed down from the family of the ancestor of Chakra in ancient times, Otsuki Kaguya, but when it was handed down to Jun Ma Lu's generation, the atavistic genes in the bloodline were already minimal.

It can be seen that in this generation of the Kaguya clan, except for Jun Maro, who has well awakened the blood inheritance limit corpse bone vein and inherited the characteristics of Kaguya's appearance, all the other Kaguya clansmen are black-haired, and they have no brains and only know how to fight, kill and destroy.

In contrast, Kimimaro obviously has more space for rational thinking, and is closer to Kaguya's appearance, which shows that his atavistic phenomenon is more obvious, but the mutilated bloodline gene and the premature awakening of the bloodline limit have led to the outbreak of Kaguya's blood-based illness.

This is also the reason why Yu didn't try to take him to Tsunade for treatment, because this is not a problem that medical ninjutsu can solve, and Yu's current strength in medical ninjutsu is almost the same as Tsunade, and the problem he can't solve Tsunade can't solve.

"So it looks ......"

"The situation in Junmaro is much more complicated than I thought......"

After putting down the genetic sample in his hand, Yu pondered for a while, and finally sorted out his thoughts, "His blood succession illness should only be combined with the Uchiha clan, the Thousand Hands clan, and the Uzumaki clan to restore the complete bloodline of the big barrel of wood feather coat......"

"Then combine the genes of the Hyuga clan and the Otsuki clan on the moon to restore the complete bloodline of Otsuki Kiyu Village, and finally combine the two to restore the bloodline of Kaguyahime, so that it is possible to make up for his gene chain defects and awaken a complete corpse bone vein - kill the ashes bone ......"

It does sound very complicated, but after a while of feather peeling back the cocoon, at least the only way to cure Jun Maro has been found.

"Now the genes of the Uchiha clan, the Thousand Hands clan, and the Uzumaki clan have ......"

"The genes of the Hyuga clan are not a problem, so the next thing is only the genes of the big barrel wood clan on the moon!!"

After thoroughly analyzing the solution to the blood succession disease in Jun Mario's body, without further ado, Yu put the four genetic samples in his hand into the different space of the realm king, and the whole person disappeared in the ninja hospital in an instant.

……

"Anyway...... The Fire Nation is so big......"

"It's like looking for a needle in a haystack......"

In the Land of Fire, in a forest dozens of kilometers away from Konoha Ninja Village, Yu couldn't help but let out a whining.

After leaving Konoha Village, he, Haku, Junmaro, and Hinata had been looking for three or four days in the forests within the Fire Country, but they still had no clue.

According to the setting in the Naruto theatrical version of "The Last", the mysterious cave suspected to be the ruins of the Otsuki clan should be located in the land of fire, not far from the Konoha Ninja Village, surrounded by a huge river and waterfall in the middle in addition to the dense forest.

"If I'm not mistaken......"

"It should be around here, why didn't I find anything, it doesn't make sense. ”

With all his strength to see and hear the domineering spirit and explore around, Yu couldn't help but let out a long whining sound.

"I don't know what you're looking for, Ha-sama......"

Bai walked unhurriedly beside Yu, still with a warm smile on his face, "But we've been wandering around this forest for days......

"I'm sorry Hinata, but I took you out and followed the three of us here for so many days......"

Glancing at Hinata, the girl who was silently following him, Yu said to her with some apologies.

It's not that he hasn't tried to use the airway to fly into the sky to search, but in the Naruto theatrical version of "The Last", it is clear that Hinata and Naruto are sitting in the eagle drawn by Sakai's super pseudo-beast can be found in this vicinity at once, but he has been looking here for so many days without any clues.

"No, it's okay......"

Hearing Yu's gentle voice, Hinata, who was shy, turned red, and said in a thin voice, "As long as I can help everyone......

"Wait a minute...... What is that?!"

At this moment, he heard the roar of a waterfall faintly in the distance, and Hinata, who opened his white eyes, seemed to see something, and suddenly his eyes widened, "Brother Yu...... Found it!!"
