"Only a fool would stand still and take a beating!"
"If you have the guts to use a blade against me, then don't run! Take a punch from me instead!"
"Will taking one punch settle everything?"
"Don't use your Hydrification Technique! I'll just give you a light punch, I swear!"
"I don't believe you at all!"
Kei took off running.
Tsunade's face was bulging with veins. If he really stopped obediently to get beaten up, wouldn't he be meeting his great-grandmother in no time?
Oh— I have [Sage Body], so I probably wouldn't meet my great-grandmother.
But it would still hurt!
Damn it, why didn't [Invisible Execution Slash] have such a high activation rate earlier? As Kei ran, he couldn't help but complain in his mind.
Just now, he really just wanted to show Kushina how he could use a wooden stick to condense a chakra scalpel.
With his current chakra control and medical ninjutsu skills, even though the wooden stick had no chakra conductivity, through sheer force and a miracle, he could still manage to form a chakra scalpel.
But who would've thought, in over an hour of experimentation earlier, the activation rate of this skill was only about one percent. Why did it suddenly activate so easily now?
Good thing it only shaved off an eyebrow. If it had been somewhere else, Tsunade wouldn't just be chasing him; she'd be out for blood.
"Hehe~ Tsunade-nee, time to eat!"
Kushina stood at the entrance, smiling as she called out to Tsunade, successfully saving Kei.
Just earlier, while cooking, she had caught a glimpse of the bloody mess in the courtyard and knew that today's lunch menu would have to change. As for those two chickens that were sliced to pieces, may they rest in peace.
"Kei! Don't let me catch you!"
Tsunade stopped, gritting her teeth as she glared at him standing over ten meters away.
She secretly made up her mind, she had to figure out a technique that could instantly push her speed to the limit. Otherwise, if she kept getting tricked , she wouldn't even be able to catch him, let alone beat him!
"It was just an accident! You know me, I'm the most reliable guy!"
"I've been researching all morning on how to solve your problem, and I've already made some progress!"
Kei started spouting nonsense without hesitation.
"You researching how to solve my problem? Or researching how to solve me?"
Tsunade raised an eyebrow.
At the entrance, Kushina was struggling to hold back her laughter. Her face turned red, and her whole body trembled.
Don't laugh. Don't laugh.
Her boyfriend had almost completely fooled Tsunade. If she laughed now, it would ruin everything!
"Shouldn't there be some trust between people?"
"Didn't you see how much Kakashi improved from my treatment the other day?"
Kushina looked at Kei skeptically. She had witnessed Kakashi's changes with her own eyes. Though she wasn't sure if any issues would arise during his next mission, his communication with others had indeed improved significantly.
"Absolutely! Not a single lie!"
Kei's tone was full of sincerity. He knew exactly how effective his system's abilities were. The results were guaranteed!
Tsunade pursed her lips, staring at Kei for a few seconds. Seeing that his gaze was steady and unwavering, she finally chose to trust him, at least for now.
She turned and walked into the house.
"We'll talk after lunch."
Kushina, still holding back her laughter, silently gave her boyfriend a thumbs-up. He actually managed to pull it off, impressive! Kei shot her a smug look, patted his backside, and walked into the house.
After a hearty lunch, Tsunade began asking Kei about his treatment method. As a medical-nin, she had thought about how to treat her own psychological issues.
But precisely because she was a medical-nin, she also understood her own mental blockages very well. If she didn't confront the things that had happened in the past head-on, then, not only would treatment be ineffective, but it would only deepen her suffering.
However, Kei's proposed treatment method was different from what she had imagined.
Sealing all memories and constructing an entirely new life within a genjutsu—from birth to adulthood—gradually adapting to the sight of blood...
"No need to face the past directly?"
Tsunade's expression became slightly dazed. She knew that this method also carried considerable risk. If she failed to distinguish between illusion and reality in time…
But if she didn't confront it… After a long silence, she motioned for Kei to follow her into the bedroom and lay down voluntarily.
He took a deep breath, formed hand seals, and quickly constructed an enormous genjutsu scene.
Tsunade's vision blurred, and the next moment, her consciousness sank completely into darkness. Her sight, hearing, smell, touch, and taste—every sense was now under the influence of the illusion.
A powerful spiritual energy rapidly sketched the memory-sealing technique of the Uzumaki clan in her mind.
System, grant [Crimson Frenzy] to Tsunade.
A full minute later, after finally finishing the genjutsu setup, Kei let out a deep breath. This genjutsu he had just performed, in terms of difficulty alone, it was already at an S-rank level.
But the time span was just too long!
Simulating a full six years of someone's life within a genjutsu, from constructing environments to sensory feedback, down to NPC interactions—it was an unimaginably massive project!
If not for [Seeker of Origins], which had significantly accelerated his ability to extract and construct memory palace imagery, It would've taken him more than five minutes just to finish setting up this genjutsu!
Kushina wiped the sweat from Kei's forehead. In her impression, whenever her boyfriend used a genjutsu, it was usually as simple as widening his eyes and slapping his palm down, done in an instant.
This was the first time she had seen him exert such effort.
"I'm fine! More than fine! I think… I've figured out the principles behind Tsukuyomi and Kotoamatsukami!"
Kei's eyes gleamed with excitement.
Perhaps it was the combined effect of [Yin Release Mastery] and [Seeker of Origins], through the immense effort required for this genjutsu, a sudden flash of insight had allowed him to grasp the mechanics of Tsukuyomi and Kotoamatsukami!
Tsukuyomi's control over time, space, the five senses, and material composition was relatively simple. With a bit more refinement, he estimated he could recreate an illusion identical to Tsukuyomi in just a few days!
Kotoamatsukami's subconscious implantation and mind control were a bit trickier. Especially the ability to cast it stealthily without the target realizing—he would need to study that further. But as long as he had a lead and understood the general principle, it was only a matter of time before he fully cracked it.
"Hm? What technique?"
Kushina blinked in confusion, staring at her boyfriend.
"The Uchiha clan's most powerful genjutsu, embedded within the Mangekyō Sharingan."
In his mind, he was already planning how exactly to educate his enemies in the Tsukuyomi space.
Would [Invisible Execution Slash] still work in a genjutsu space?
A surprise attack triggering out of nowhere, the fear that would instill in an enemy was way more intense than a straightforward stabbing!
And then there was...
The effect of [Euphoria Healing]... would it activate inside a genjutsu?
Three days of ultimate pleasure condensed into a single instant…
Why didn't he capture Danzō earlier today?! Now he couldn't even find a suitable test subject!
