The Hokage, having traveled here, of course he'd unify the ninja world!

Chapter 446 Teaching

Uchiha clan.

Orochimaru's laboratory.

Kato Dan was using the Spirit Transformation Technique with his eyes closed. Standing next to him was a little girl, Kurama Yakumo, who also had her eyes closed.

She also used the Spirit Transformation Technique, but she already had a soul clone, Idu, outside, so at this moment it was equivalent to her own consciousness controlling Idu.

Let Ido follow Kato Dan's soul, passing through layers of walls, to the prison below.

The people imprisoned here are mostly from the Sarutobi clan, selected last time using Minato's malicious perception.

Now it's perfect for conducting experiments.

In a world unseen by ordinary people, Kato Dan demonstrates to Ido how to invade an enemy's body and how to kill the enemy.

"There are two ways to kill someone: one is to forcibly control the enemy's body."

"Another method is to directly shatter the other person's soul."

“A battle of souls is extremely dangerous. In comparison, the first one is less dangerous. If we fail to dominate, we can escape from the other's body.”

"The second one is extremely dangerous; if we are not careful, our souls may be damaged."

“Soul damage may cause a coma, memory loss, or emotional deprivation; in severe cases, the person may never wake up or die.”

"However, Yakumo, you have an advantage over others because Ido is your second soul, which gives you room for error."

“If Idu is injured, it will not affect you personally.”

"Now I'll demonstrate, and you can follow along."

"Yes, teacher!"

Two people in a cell started dancing uncontrollably.

Then he went to the wall and slammed his head against it until blood splattered and he fell silent.

The Sarutobi tribesmen nearby screamed in terror.

Because they had no idea who their people really were.

The next moment, the two people froze, their eyes glazed over, and they fell straight to the ground, followed by the next one.

Although Edo had done similar things before, this was the first time he had ever carried out such a systematic and efficient killing.

The six people in this cell died one after another within seconds.

Jirobo and Kidomaru, who came from Otogakure, opened the cell door.

Kidomaru spat out spider silk and tied up the corpses of several people.

Jirobo helped carry the body out.

Orochimaru is currently refining the Cursed Seal, and the four members of the Orochimaru group are currently being used as test subjects in the laboratory.

Kato Dan and Kurama Yakumo, who were in the laboratory, also opened their eyes at this moment.

"Indeed, your talent surpasses mine, and further improvement is only a matter of time."

"Remember, if you encounter someone with an exceptionally strong soul, relinquish control over Idu."

"Because if Idu is killed, he can be reborn from your body. If your soul is damaged, it will endanger your life."

"Yes! Thank you for your guidance, Teacher Duan!"

Kato Dan was also surprised that the Kurama clan was so suited to the Spirit Transformation Technique, and that the Spirit Transformation Technique was even safer than his own.

"I'll have Shisui teach you about illusion magic."

"The great war in the ninja world is about to begin. Your Ido can cast wide-range environmental genjutsu, which is very advantageous on the battlefield."

Although Yakumo Kurama is a bit young, she believes in the principle of "the capable should do more," and she wouldn't let go of such an opportunity to train.

Kurama Yakumo originally wanted to revitalize the Kurama family, and at this moment he was full of fighting spirit.

"I will keep working hard, Teacher Duan, and I will definitely revitalize the pommel horse race!"

Kato Dan nodded slightly: "It's good to have confidence, but don't go around publicizing things you haven't accomplished. That will only let others know your weaknesses."

Yakumo Kurama nodded thoughtfully, keeping those words in mind.

……

Inside the lab next door.

Ying took off her clothes and lay face down on the operating table.

Red Bean formed a seal on his hand, extending along the earth spider seal on Ying's back.

"You're lucky; you can gradually add more seals, but I inscribed them all at once."

"It almost killed me with pain."

There was a hint of envy in Hongdou's tone.

The secret seal of the Earth Spider Clan behind Ying is the core that attracts natural energy.

Now, all that's needed is to gradually expand and strengthen the existing foundation, and Ying will be able to freely absorb natural energy to cultivate immortal arts.

Ying only felt a burning sensation in her back, but she could still bear it.

Hearing this, she was somewhat surprised: "So, Teacher Hongdou is going to take off all her clothes too?"

Red Bean blushed, remembering the sensation of Orochimaru's fingers brushing against her body.

"Yes, the seal must be drawn in one go."

Ying was already shy enough about stripping naked in front of Hongdou, and upon hearing this, she said with a hint of gossip:

"So... what does it feel like for Anko-sensei to strip naked in front of Orochimaru-sama...?"

Hongdou sensed the teasing in Ying's voice, and feeling somewhat embarrassed and annoyed, he pressed his hand firmly against Ying's back.

"You little brat, how dare you tease me?"

"what……"

Ying cried out in pain.

"Teacher Hongdou, I was wrong, I was wrong."

Ying quickly begged for forgiveness.

After the talisman is inscribed, the red bean needs to absorb natural energy every day to mix with sage chakra and deepen the inscription of the talisman.

Because Ying has the Earth Spider Seal engraved on her back, which is exactly the same as Orochimaru's research direction.

Upon further inspection, Orochimaru discovered that Hotaru's Tsuchigumo seal was a complete set of seals that required no modification.

However, it can be expanded based on the existing capacity.

Since Ying is young, the treatment can be gradually expanded from the original level, so there is no need to bear the risk of receiving the curse seal.

Orochimaru was quite busy, so he simply handed the matter over to Anko.

This will not only allow Hongdou to get some exercise, but also allow her to teach Ying nearby.

Ordinary ninjas are basically left to their own devices after graduating from the ninja academy and being led around by their instructors a few times.

Ordinary people could earn new ninjutsu in the village by doing good deeds, or slowly save money and pay others to teach them.

Ying was the only one left in her family, and it was only because the Uchiha clan took her in that she received such good treatment.

Hongdou has been taking care of Ying for a while now, and the two are getting along quite well.

Especially in terms of her talent for learning ninjutsu, Ying learned very quickly.

As a result, in addition to absorbing natural energy to synthesize sage chakra and inscribe talismans every day, Hongdou now has to practice on her own.

After all, it's a small matter to be exhausted, but a big matter to lose face.

Their relationship progressed very quickly.

After some playful fighting, Ying's engraving session for the day was over.

As she was getting dressed, Hongdou spoke up:

"War will break out soon. This time, you'll come with me to see what the Ninja World War is like."

Ying was somewhat surprised: "The Fourth Shinobi World War is about to begin?"

They had learned about the previous Ninja World Wars while they were at the Ninja Academy. They never expected that their generation would have to fight again so soon after graduating.

Red Bean appeared quite relaxed; after all, she had only glimpsed the tip of the iceberg of Orochimaru's formidable power.

"Our Konoha is quite strong, so you don't need to worry. Otherwise, we wouldn't have had the opportunity to watch the battle."

Ying seemed to be deep in thought.
