Grouping Begins

---

Muzan didn't study his own cells in the hospital laboratory. The strength of his cells was comparable to Hashirama's body, and he didn't want to become a guinea pig in Orochimaru's lab.

Instead, he used a microscope to observe animal cells. The hospital had a large supply of cells for research, even some rare bloodlines. After a series of studies, Muzan took notes and then noticed Tsunade behind him, her head stretched out.

He couldn't help but notice her figure, her dedication to the world, and her immense tolerance.

"Ahem, Tsunade-sama, what can I do for you?" he asked.

"I see that your research direction is all basic. I left a lot of notes at Konoha Hospital. You can go read them," Tsunade said, extremely satisfied with Muzan's attitude. Even if Muzan pretended to be expressionless, Tsunade keenly noticed the two seconds his eyes lingered unintentionally. It seemed that the Yin Seal had not failed!

"However, I am short of errand boys. During this time, go to the wine shop and get me a drink!" she commanded.

She hated such sanctimonious people the most. They could watch if they wanted, but they should at least acknowledge her attractiveness.

If Muzan knew Tsunade's true thoughts, he would definitely sneer. There was also the senior Jiraiya in front of him, who was not afraid of dying.

Buying wine for Tsunade was not without its rewards. As a pioneer of medical ninjutsu, Tsunade gave Muzan a lot of training suggestions for techniques such as the Mystical Palm Technique. There was also a lot of medical knowledge that couldn't be learned in the hospital. Tsunade had no intention of keeping it secret and taught all of it to Muzan, who could be called Tsunade's registered disciple.

This allowed Muzan's strength to improve rapidly in a short period of time.

"My cells are highly infectious; even a ninja's body can't resist them," Muzan noted.

To advance his research, Muzan independently applied for a small laboratory next door and obtained some Jonin cells. The progress of his experiments gave Muzan a general idea of himself.

"The stronger a person is, the greater their strength will be after becoming a demon. Of course, special bloodline abilities cannot be ruled out. Maybe the combination of the two will promote a stronger effect," he theorized.

"However, there are also risks," he thought, remembering the rabbit used in an experiment, which exploded because it couldn't bear Muzan's strength.

"It's a pity that now is not the time to develop our power. When the Third Ninja War comes, the more chaotic it is, the greater my chances will be," he mused.

Muzan recorded the experiments he had just completed. These were precious experimental data. After packing them up, he put them into a sealing scroll.

"If I remember correctly, today is the graduation day of the Ninja Academy. The Third Hokage specifically asked me to come over. It seems that they have found a good teacher for me," he thought.

Due to Tsunade's refusal, the Third Hokage had not yet found a teacher for Muzan. Kakashi's trajectory had not changed; during this period, Minato became Kakashi's teacher, pulling Kakashi into the Hokage faction.

Today's Ninja Academy was extremely lively. Many students were wearing the mark representing Konoha Ninja. From today on, they were Konoha's Genin!

"Hey! I actually saw Muzan!"

"Oh my god, is it really Muzan? Long time no see!"

"This bastard still likes to wear black robes. There is no change from before."

"Hope Muzan will form a team with us. The other party is a medical ninja. If a team member is injured, he can treat us!"

It was inevitable for ninjas to get injured on missions. Most ninjas would bandage themselves, but if the injury was serious, they needed to go to Konoha Hospital to find a doctor, which was a big expense.

This money could be saved if there was a medical ninja in the team.

Therefore, everyone was looking forward to forming a team with Muzan.

Kakashi, who was still in a daze, felt a little excited when he saw Muzan, but his tone was still unkind.

"Brother, I thought you fell asleep in the laboratory and would miss today's grouping."

Since Kakashi became a Genin, he rarely went home. He had been doing missions to accumulate merit and improve his strength. With Minato as a teacher, they could go anywhere with their mobility.

"How is it possible? I have been paying attention to today's events for a long time. You came to the Ninja Academy just for a formality," Muzan replied.

Noticing Kakashi's dead fish eyes, his behavior was more like that of a mature ninja. He was always on guard. Even in Konoha, this habit continued.

It seemed that this period was of great help to Kakashi's growth. Fortunately, Muzan's presence delayed the failure of his father's mission and did not cause Kakashi's cold and indifferent character.

He was also looking forward to seeing who his teacher would be.

"It's really just a formality. Now I hope my teammates won't drag me down too much. After all, I'm too strong," Kakashi said.

Just after saying this, Obito and Rin walked over. Especially Obito, who hadn't awakened his Sharingan yet. He even doubted whether he was an adopted child of the Uchiha family. When he heard Kakashi's pretentious words, Obito was the first to push through.

"Tch! A bastard like you definitely doesn't have any teammates," Obito retorted.

"Don't talk about Obito like that..." Rin interjected.

Obito, who wanted to continue arguing, put away his temper after being interrupted by Rin. Looking at Rin's eyes, he was extremely jealous. When he awakened his Sharingan, he must make Kakashi look bad!

"Maybe you will become teammates," Muzan suggested.

After hearing Muzan's words, Obito and Kakashi both said it was impossible.

"Whoever teams up with him will directly lower the level of the team! I don't want to fail the mission because of him!"

"Asshole! You will only kill your teammates! Only a devil will be your teammate!"

Just as they were arguing, a tall figure walked into the classroom, and Muzan was the first to notice the strength of the other party.

"Jonin? It seems that Konoha attaches great importance to the students of this class."

"Uchiha Hina, Haruno Kawakiyo, Ito Tsuki, the three of you are following me."

As the first teacher entered, the students heard the message from the leading teacher one after another.

"Kakashi, Obito, Rin."

A gentle voice called out, and the iconic golden hair attracted the attention of the students present.

"Sorry to keep you waiting."

"It's actually Minato! He's personally leading the team! Rin and I are still on the same team, but why is Kakashi also on the team?" Obito exclaimed incoherently.

Minato was now listed by the major ninja villages as a powerful ninja who could abort missions immediately after seeing him. He was among the best of the younger generation.

"Tch, you think I really want to be with you?" Kakashi retorted.

"You!"

Seeing the tit-for-tat confrontation between the two, Muzan suddenly felt a creepy delusion, and then a hoarse voice sounded...
