The Uchiha was just about to say hello to Kakashi when he saw the three-hooked jade writing wheel eye in Kakashi's eye socket.

Uchiha Yuan was stunned for a moment, and then immediately thought that Obito and Kakashi should have awakened the Kaleidoscope Sharingan at this time, and Rin was already dead.

Bo Feng Shuimen's current state is obviously not very good, but he still forced a smile and asked the Uchiha Yuan for the specific details of some missions, and after confirming that there was no problem, he let the Uchiha Yuan leave.

Uchiha and Shisui were about to leave the Hokage's office when Bo Feng Shuimon suddenly stopped them, "Yuan, you wait a minute."

"Hokage-sama, is there anything else?" Uchiha turned around and asked.

"Yuan, you are a member of the Uchiha clan, you should know the reason and law of the evolution of the writing wheel, Kakashi is not from the Uchiha clan, and his writing wheel eye will not have any bad effect on him if it evolves from two to three hooks, right?"

"Probably not, it's just that the consumption of chakras will increase a bit, and Kakashi will have to be more careful when using chakras in the future."

After listening to Uchiha Yuan's words, Bo Feng Shuimen was obviously relieved.

Obito and Rin are dead, and he doesn't want his last disciple, Kakashi, to have an accident as well.

"Then Hokage-sama, if it's okay, I'll go first."

Bo Feng Shuimon nodded, and turned his gaze to Kakashi.

......

Coming out of the Hokage's office, the Uchiha sent Shisui home, and then came to Orochimaru's laboratory.

Orochimaru's main focus during this time is still on studying Bai Jue's corpse, and when he encounters a research bottleneck, he will occasionally dissect the corpses of some other village's blood inheritance limit ninjas to adjust his mood.

Because the more he studied, Orochimaru felt that the more interested he was in Bai Jue, this guy was really amazing.

"Orochimaru-sama, has there been any new progress in Aina's research in the past two days?" Uchiha asked the busy Orochimaru and Hinata Ayana.

Hearing Uchiha Yuan's voice, Hinata Ayana stopped his research and said, "Yuan, according to my analysis with the teacher in the past two days, we found that the internal structure of this corpse is very similar to that of a human, and Orochimaru-sensei even thinks that he was once a human, but he was somehow turned into this."

Uchiha Yuan was a little surprised when he heard this, he didn't expect Orochimaru to be able to discover the fact that Bai Jue was once a human through Bai Jue's corpse.

And Hinata Ayana saw Uchiha Yuan's expression, thinking that he was like himself, and he couldn't believe it when he first heard Orochimaru say this.

"Yuan, you may think it's incredible, but according to multiple sets of genetic comparisons, more than 90% of this corpse may be human." Orochimaru added.

Uchiha, who has read the original book, knows very well the origin of Bai Jue, and Bai Jue was indeed a human being, and it was the product of the Infinite Moon Reading released by Otsuki Kaguya to humans back then.

It's just that Orochimaru can even study this, which gives Uchiha Yuan a new understanding of his scientific research ability.

"Orochimaru-sama, is it useful for us to make sure this guy was once human?" Uchiha asked with a quick turn of words.

"Of course it works, if nothing else, just his special transformation technique, we can learn it." Orochimaru licked his lips and replied.

Uchiha Yuan's eyes lit up when he heard this, there are a lot of special abilities of Bai Jue in the original book, if he can really learn these techniques, it should be very useful, right?

But soon Uchiha Yuan calmed down, he didn't come to Orochimaru for Hakuju, but for another purpose.

"Orochimaru-sama, there's something I'd like to confirm with you." Uchiha said in a serious tone.

"What's the matter?"

"Orochimaru-sama, do you have an eight-tailed horn?"

Hearing Uchiha Yuan's question, Orochimaru turned his head to look at Hinata Ayana and then nodded in acknowledgement.

Hinata's expression under the mask was a little helpless, she really didn't tell Uchiha Yuan about it, but Orochimaru had obviously decided that it was her "inner ghost" who leaked the information.

Fortunately, Orochimaru is right

He didn't care, he also knew that the relationship between Uchiha and Hinata Akina was extraordinary.

Orochimaru didn't dwell on this topic, but changed the conversation and said, "Yuan, I can give you the horn of the Eight Tails, but I need more of this guy's corpse."

"How much?" Uchiha asked.

"Ten."

"It can't be!" Uchiha Yuan decisively refused.

The only corpses in his hand were the five white bodies that he had killed on the Bear Country's side and monitored him.

One of them was already on Orochimaru's mobile phone, and there were only 4 left in his hand, and he couldn't take out 10 at all.

"How much can you take out at all?" Orochimaru asked.

"1."

Orochimaru shook his head, "1 is too little."

In the end, after some bargaining, the two sides settled on 3 white corpses in exchange for the horns of the Eight Tails.

Uchiha Yuan directly took out the three corpses of Hakujue from the sealing scroll and handed them to Orochimaru.

After confirming that there was no problem, Orochimaru turned his head to the sun and said to Aana, "Aana, you can take the horn of the Eight Tails with you!"

Hinata Ayana nodded, took off her research coat and left Orochimaru's research institute with Uchiha Yuan.

"Far away, how many more of these corpses do you have?" After coming out of the research institute, Hinata asked.

"There's one more, and I've got five corpses in total." Uchiha replied.

"Yuan, you must keep the remaining 1 corpse, don't give it to others, Orochimaru's research will soon make a breakthrough, you keep this corpse, and we can reproduce some of Orochimaru's research results in the future."

"Don't worry! I'll take good care of it."

Hinata, then, took Uchiha to a forest outside Konoha Village.

After walking a few steps through the woods, Hinata stopped near a pile of stones, and then she untied the nearby barrier with both hands, and a small iron door appeared on the ground.

Opening the iron door, Uchiha and Hinata Ayana entered the research institute together.

After entering the underground, the Uchiha looked around with some surprise, the space here was very large, and there were many strange things placed in it.

The Uchiha was a little curious and kept looking left and right, while Hinata Ayana was in charge of explaining, a scene that looked like a museum tour guide taking visitors on a tour.

Soon Uchiha Yuan and they came to the second basement floor, and Uchiha Yuan saw the horn of the Eight Tails placed in the glassware at a glance.

The horn of the Eight Tails looked close to the size of two people, and the Uchiha could clearly sense that this horn contained the massive chakra as he stood next to the glassware.

"It's worthy of the Eight Tails, Chakra is really huge!" After saying that, Uchiha Yuan put the glassware with the eight-tailed horns into the storage ring.

At this point, Uchiha Yuan has one, five, seven, and eight chakras of tailed beasts in his hands.
