Naruto: Mikoto, Tsunade won't let anyone go.

Orochimaru never expected that Uchiha Kakuzan would even consider recruiting him. After a slight pause, a meaningful smile appeared on his face.

"King Qiu, you really surprise me."

At this point, Orochimaru paused slightly, then continued:

"I appreciate your kind offer, but I don't have anything that interests me, so I'll pass."

At this stage, Orochimaru has basically completed his research and development, which has brought his survival ability to the extreme. Even when facing people like Madara Uchiha and Okazan Uchiha, who stand at the pinnacle of the ninja world, he can barely protect himself, which is why he refused their courage.

Moreover, Orochimaru is currently coveting the Uchiha clan's bloodline limit.

However, because Uchiha Kakuzan had moved the Uchiha clan to an overseas island early on, even those Uchiha clan members who went out to travel were at least Jonin in strength, and they were always in groups, which is why Orochimaru was unable to succeed.

Therefore, Orochimaru himself was well aware that as long as the man in front of him was still alive, they would be enemies sooner or later.

Hearing Orochimaru's words, Uchiha Kakuzan wasn't particularly surprised. After tilting his head slightly, he stared intently at Orochimaru, uttering words that caused Orochimaru's expression to change slightly.

"Orochimaru, you should have finished researching your Reanimation Jutsu by now, right?"

"That guy Kabuto should have already told you about my experimental progress and all the research results, right?"

Kabuto Yakushi can be considered Orochimaru's most capable assistant, so as long as Kabuto put in a little effort, he can basically get his hands on all of Orochimaru's experimental results.

However, to Orochimaru's surprise, Uchiha Kakuzan shook his head after hearing what he said.

"I am not interested in the Reanimation Jutsu. Of all your research, only the Impure World Reincarnation Jutsu is somewhat interesting and useful to me. As for the others, I don't care much about them."

At this point, Uchiha Kakuyama raised his eyebrows slightly and continued:

"Moreover, Kabuto has already been attracted by your personal charm. If it weren't for Madara Uchiha's appearance, he actually planned to follow you all the way."

Upon hearing Uchiha Kakuzan's words, a flicker of emotion flashed in Orochimaru's eyes, and he continued:

"Never mind, Kabuto's research skills are no less than mine, and I don't have much left to teach him."

Uchiha Kakuzan nodded, understanding Orochimaru's meaning, and shook his head with some regret, saying:

"That's a real shame. I was thinking of joining forces with you to study the Otsutsuki clan."

Upon hearing Uchiha Kakuzan's words, Orochimaru's heart skipped a beat, as if he had heard something very important to him. He hesitated for a moment before saying:

"The Otsutsuki clan? I feel like I've heard of them somewhere before?"

Even in the entire ninja world, Orochimaru can be considered one of the most learned people, having read countless ancient documents.

So when I heard the surname Ōtsutsuki, I had a vague feeling that I had seen it somewhere before, but I just couldn't remember where.

Upon hearing Orochimaru's words, Uchiha Kakuzan revealed a playful smile.

“You’ve naturally heard of it, because the surname Otsutsuki is recorded in the clan history of our Uchiha clan. Although you haven’t read the clan history of our Uchiha clan, it should also be recorded in the clan history of the Senju clan.”

Upon hearing Uchiha Kakuzan's suggestion, Orochimaru seemed to remember something; his pupils contracted sharply, and a fanatical glint appeared in his eyes.

"Otsutsuki, the Otsutsuki clan, I remember now, the legendary Sage of Six Paths seems to have the surname Otsutsuki."
