Konoha: Who is the good person?

"Only an idiot would stand still and get beaten!"

"You bastard! You dare use a knife on me? Don't you run! Take a punch from me!"

"Can we just forget about this after one punch?"

"Just don't use your Water Release. I'll just give you a light punch and we can call it even!"

"I don't trust you!"

Yamanaka Kei sprinted away.

This woman's veins were popping out on her forehead.

If he honestly stopped to get beaten, wouldn't he be meeting his great-grandmother right then and there?

Oh~

I have the body of a sage, so I probably wouldn't see my great-grandmother.

But it would still hurt!

"Damn it, Invisible Guillotine! Why didn't I see you trigger with such a high probability earlier!"

Yamanaka Kei ran while mentally complaining like crazy.

He really just wanted to show Tsunade how to condense a chakra scalpel with a wooden stick.

With his current chakra control and mastery of medical ninjutsu,

even if this little wooden stick had no chakra conductivity, with enough force, condensing a chakra scalpel wouldn't be too difficult.

But who would have thought?

Luckily, it only shaved off her eyebrow. If it were somewhere else, Tsunade wouldn't just be chasing him to beat him.

"Hehe~ Tsunade, it's time to eat!"

Kushina stood at the entrance, smiling as she called out to Tsunade, defusing the situation for Yamanaka Kei.

Earlier, during a break from cooking, she glanced at the scene of flying blood in the courtyard and knew that they would have to change a dish today.

As for those two chickens that were sliced and diced, may they rest in peace.

"...Yamanaka Kei! Don't let me catch you!"

Tsunade stopped and glared at the little bastard who was standing more than ten meters away from her, gritting her teeth.

She secretly made up her mind.

She definitely had to research the technique that could instantly increase speed to the extreme later.

Otherwise, if she were to be at a disadvantage in the future, she wouldn't be able to catch up, so what was the point of fighting!

"Ahem, Tsunade, that was just an accident. You know I'm the most reliable person!"

"You? Reliable? Hmph~"

"I've been researching how to solve the problems you have all morning, and I already have some preliminary results!"

Yamanaka Kei didn't even need to draft anything; he just blurted it out.

"Are you researching how to solve my problems, or are you researching how to get rid of me?"

Tsunade raised an eyebrow.

Kushina, at the entrance, saw that Tsunade was missing an eyebrow and was holding back her laughter until her face was red and she was trembling.

I can't laugh, I can't laugh.

My boyfriend is almost tricking Tsunade into being disabled.

If I laugh now, it'll be a disaster!

"Can't there be a little trust between people?"

"Hmph~ No."

"My dear sister! You saw the effects of Kakashi's treatment a few days ago."

"...Are you serious?"

Tsunade looked at Yamanaka Kei, full of suspicion.

She had seen Kakashi's changes.

Although she didn't know if any problems would be exposed again during the next mission,

there had indeed been a significant improvement in his communication skills.

"Really, really! Not a single lie!"

Yamanaka Kei's tone was very sincere.

He knew the power of the system's entries better than anyone else.

They were absolutely effective!

Tsunade pursed her lips and stared at Yamanaka Kei for a few seconds. Seeing that his eyes didn't waver,

she ultimately believed his words for the time being.

She turned and walked into the mansion.

"Let's talk after lunch."

Kushina held back her laughter and silently gave her boyfriend a thumbs up.

He tricked her! Amazing!

Yamanaka Kei gave Kushina a smug look, patted his butt, and also walked into the house.

After a hearty lunch,

Tsunade began to inquire about Yamanaka Kei's treatment methods.

As a medical ninja, she had thought about how to treat her own psychological problems.

But precisely because she was a medical ninja, she also knew very well where her problem lay. If she couldn't face the things that had happened in the past,

the treatment wouldn't have any effect and would only make her more painful.

However, the treatment method Yamanaka Kei proposed was somewhat different from what she had imagined.

Sealing all memories and constructing a new life with genjutsu, from birth to adulthood, gradually adapting to blood...

"Don't I have to face the past?"

Tsunade's expression was a little dazed.

She knew very well that this kind of treatment also carried considerable risks. If she couldn't distinguish between genjutsu and reality in time...

But if she didn't have to face those...

After a moment of silence, she beckoned to Yamanaka Kei and took the initiative to walk into the bedroom and lie down.

Yamanaka Kei took a deep breath, formed hand seals, and quickly constructed a huge genjutsu scene.

After a moment of恍惚 in front of Tsunade's eyes, her consciousness completely fell into darkness. Sight, hearing, smell, touch, and taste were all affected by the genjutsu.

The powerful Yin Release energy quickly outlined the Uzumaki clan's memory sealing technique in her mind.

"System, give Scarlet Fever to Tsunade."

A full minute later, Yamanaka Kei, who had finished setting up the genjutsu, let out a breath of stale air.

The genjutsu he used this time.

In terms of operational difficulty alone, it was only at the level of an S-rank genjutsu.

But the time span was really too long!

Using genjutsu to simulate a person's life for a full six years, from scene construction to sensory feedback to NPC shaping, the amount of work was really huge!

If it weren't for the [Source Seer] after the upgrade, which made him several times faster when obtaining memory palace images,

he probably wouldn't have been able to complete this genjutsu in five minutes.

"Kei, are you okay?"

Kushina wiped the sweat from Yamanaka Kei's forehead.

In her memory, her boyfriend had always been able to complete genjutsu with a glare and a slap of his hand.

This was the first time she had seen him so laborious.

"Good! Very good! I seem to... know the principle of Tsukuyomi and Kotoamatsukami!"

Yamanaka Kei's eyes were frighteningly bright.

Perhaps it was the result of the combined efforts of [Yin Release Master] and [Source Seer].

This time, when he used such a large-scale genjutsu, he suddenly had a flash of inspiration and figured out the principle of Tsukuyomi and Kotoamatsukami!

Tsukuyomi's time, space, five senses, and mass control were relatively simple.

He estimated that as long as he thought about it a little more, he would be able to create a genjutsu that was exactly the same as Tsukuyomi in two or three days at most!

Kotoamatsukami's subconscious implantation and thought control were a little more troublesome.

Especially the means of performing the technique silently, without being discovered by the person under the technique, might require more research.

But as long as he had a clue and knew the general principle, he would always be able to figure it out.

"Huh? What kind of technique is that?"

Kushina blinked her eyes and looked at her boyfriend blankly.

"The strongest genjutsu residing in the Mangekyo Sharingan of the Uchiha clan."

Yamanaka Kei grinned.

He had already begun to conceive how to teach the enemy a good lesson in the Tsukuyomi space!

He also didn't know if [Invisible Guillotine] would work in the genjutsu space.

This kind of random attack that triggered unexpectedly.

The fear it caused to the enemy was much stronger than directly stabbing them!

And...

He didn't know if the effect of [Ecstasy Milk] could be triggered in the genjutsu.

Three days of extreme happiness completed in an instant...

Damn it!

Why did he throw Danzo out this morning!

Now he couldn't find a suitable test subject!
