The slug fairy smiled and replied: "The slug itself has the ability to absorb and release chakra. It is compatible with all chakra energy. I know what you want to do, let it go. My child, the slug you summoned is just a part of my body, don't worry about anything."

Upon hearing this, Uesugi Tetsu looked happy: "Thank you, Slug Fairy."

Tsunade glanced at Uesugi and thought to himself that this kid really had a clear idea, but using slug splitting and weird chakra was indeed an unpredictable attack.

When teaching chakra knowledge before, Tsunade mentioned to Uesugi Tsuki about the issue of slug psychics and schizophrenia.

Unexpectedly, Uesugi Tsuki can learn from it and learn the technique of psychics, he can actually think of combining it with his weird chakra.

not bad.

"Well, slug fairy, then we're back now." Tsunade nodded to slug fairy and said.

"Go." The slug fairy said lightly.

Then, Tsunade said to Uesugi Tsubasa: "Use the 'removal' seal, you can remove the art of reverse psychics."

Uesugi nodded, made a "release" seal, and shouted lightly, and in an instant, the sky was spinning and the scenery around him changed rapidly.

In the blink of an eye, he returned to the place where he signed a psychic contract outside the town not long ago.

Bang.

A light sound came, Uesugi Tetsuki looked back and Tsunade was back too.

"Teacher, I suddenly remembered, what's going on with the natural energy that the slug fairy just mentioned?" Uesugi Tsuna asked, looking at Tsunade.

Of course he knew what natural energy was. Although Naruto was jumping and watching, he would never know what natural energy was.

But he asked Tsunade to say what was going on in the natural energy of the wet bone forest, or the immortal mode.

"Ah, natural energy..." Tsunade said, but suddenly stopped.

"Well, natural energy." Uesugi Tsuna looked at Tsunade expectantly.

"Well, you are too young to practice." Tsunade said lightly, then walked back with a swagger.

"Hey?!" Uesugi Tsuna was stunned and quickly caught up with Tsunade's pace. "Teacher, I'm already a singina."

"There is no way to go to the top of the king." Tsunade didn't look back.

"Why?" Uesugi Tsuki asked in confusion.

"I said you are too young." Tsunade replied impatiently.

"Where am I younger?" Uesugi Tsubaki frowned angrily.

Tsunade smiled and said, "Otherwise, I'll teach you the seal first."

"It's okay... Then can I learn 'creation and regeneration'?" Uesugi Tsubasa asked expectantly. This is what he really wants to learn.

"no."

"Why?"

"You're too young."

...

After Uesugi Tsuna was so annoyed by him that he could only tell him when he mastered the Yin Seal and when he would consider creating regeneration and natural energy.

Although Tsunade seemed very reluctant on the surface, she knew very well that the chakra intensity of Sugito's current chakra was enough to learn Yin Seal, and she originally planned to hand over the practice of this stage to him.

Yin seal is the foundation. Only by mastering Yin seal can you have enough chakra to perform creative regeneration.

Otherwise, how can the amount of chakra consumed by ordinary people be able to afford to create such a huge amount of chakra?

If Uesugi Tsuki finally couldn't learn the Yin seal, then there was no need to say about creation and regeneration.

Regarding the method of using natural energy in the wet bone forest, Tsunade has not planned to tell Uesugi Tsuki yet, so let's talk about it when he has learned Yin Seal.

Although it is the foundation, it is not easy to learn Yin seal.

In the following days, Tsunade calmed down and taught Uesugi Toru with all his heart that he would go to the gambling halls. I don’t know if it was because of his lack of money.

In short, her attention was focused on Uesugi.

This made Uesugi Tsuku complain secretly. Since he began to practice Yin Seal, he had almost no time to rest. As soon as he woke up, he was forced to pull him up by Tsunade to exercise his chakra's control ability.

Even though his chakra control was not weak, Tsunade still seemed to be unsatisfied.

However, under such high-intensity practice, Uesugi Tsuki's strength has improved by leaps and bounds. Not only did the chakra control technique be improved again, but after only more than three months, a diamond-shaped logo condensed into the middle of the eyebrows.

The shape and size are the same as Tsunade's, but this color is different from Tsunade's pink, but it is black.

Although I don’t know why, both Tsunade and Uesugi Tsuna thought that it should be because of the chakra that contains dead energy.

Tsunade was really surprised that Uesugi Tsuna made such progress. This completely exceeded her expectations. Although it could not be considered as a complete mastery of the Yin Seal, at least the foundation was solid and the progress was rapid.

It took her a year to condense her mark with her peerless talent, but Uesugi Tsuki only took three months.

After condensing the mark, it can be regarded as the entry point for the Yin seal and can already store some of the chakra. Next, it will take a long time to improve and understand yourself to expand the storage volume of chakra in the mark space.

This cannot be achieved overnight, and it also requires Uesugi Tsuki to practice every day.

It's still one month before the holiday ends.

This month, in addition to urging Uesugi Toru to practice Yin Seal every day, Tsunade also taught him some basics of "creation and regeneration" in advance.

"Teacher, what kind of ninjutsu is creating and rebirth?" Uesugi Takashi looked full of knowledge.

On this day, Tsunade told Uesugi that he planned to teach him "creation and rebirth" in advance, but the premise was that he could not slacken off his practice after returning, otherwise if he failed the assessment next time, it would be no more than a fine.

When Uesugi Tetsu heard this, he finally learned the dream "creation and rebirth" that he had been dreaming of, and his heart aroused infinite excitement.

"Creation and regeneration are not just a ninjutsu, but their complexity is far beyond your imagination. The most important thing is that people who are proficient in creating and regeneration must not only have strong chakra control capabilities, but also have extremely large chakra volume and related medical knowledge."

Tsunade's detailed answer.

"Chakra control ability, chakra amount and medical knowledge..." Uesugi Shiro secretly repeated these elements in his heart.

He is pretty good when it comes to chakra control, especially during this period, he has improved a lot under Tsunade's "devil training".

It would be fine to carefully control the amount of chakra in his current mark that is three times more than he himself.
