At the end of the day, Tsunade came back to the workshop after curing the poisoned ninjas. She had already cured around 10 of them. If it was some normal ninja they would have died of chakra depletion.
Having Senju bloodline and Uzumaki bloodline helped her a lot. She has a lot of chakra inside her body which makes her more energetic than others.
When Tsunade walked into the room, the scene in front of her shocked her.
Tsukimi was playing with the mouse she was experimenting on previously. It shouldn't have been shocking as he had done this a while ago in front of her but what he was doing right now was absurd.
He was using a scalpel to dissect the mouse and the mouse was even holding his own body for the boy to work on him.
'WHAT THE FUCK IS GOING ON!!!'
Tsunade screamed in her mind as she almost imagined the mouse having an inviting look on his. Like it was saying, "come do anything you want with me I am all yours."
What happened next made her scalp go numb.
After Tsukimi made a cut on the mouse, Kokuo hurriedly used chakra manipulation to form a green energy on her hands which radiated on the cut of the mouse.
At a visible rate the cut on the body of the mouse started closing, until it was fully back to normal.
"Now it's my turn!"
Matatabi exclaimed and Tsukimi once again made a cut on the mouse. Under the dead eyes of the mature Jonin, the whole process repeated.
After the mouse was 'healed' once again, Tsunade came back to her senses and walked forward.
"What do you think you are doing?" Her cold voice echoed in the room making the trio look at her. They had already sensed her but chose to ignore her focus on the fun activities in front of them.
" Of Course We are Pla-" before Matatabi could complete her sentence Kokuo sealed her mouth with her hands and continued for her.
"We are practicing." A light flashed her little eyes as she nodded with a sagely look. Her words caused the older woman's lips to twitch as she turned to look at the boy to see his reaction.
To her shock the boy was preparing to make another cut on the eager mouse who laid on the table with its libs spread.
"Why are you still continuing?!"
She screamed, scaring even some of the people working outside. They wanted to walk in and check but did not have the guts to walk in on the demoness.
"My turn is still left."
Tsukimi replied in a matter of fact tone, his eyes locked on the mouse on the table and to Tsunade's surprise after a moment of thought the boy placed the scalpel down.
She thought he gave up but hse did not know how wrong she was until the next moment
Placing the scalpel down Tsukimi raised his finger which glowed in blue light and his chakra started to reform and materialize.
"Chakra Scalpel Jutsu!"
Tsunade could only mutter in shock as Tsukimi made a cut on the mouse and them used the basic healing technique to heal the cut.
'What a monster. His chakra control is so good that he does not leak much residual chakra in the air. The sharpness and the form of the scalpel is so precise. It looks like the mouse did not even know that it was a cut and healed in no time. I wonder how did he make the mouse willingly become a torture subject for him.'
Tsunade's mind spun at full speed as she noticed minute details in the medical techniques. She was not a skilled ninja for nothing, all the surface details of the technique Tsukimi used were caught by her sharp eyes.
At first she thought that only the boy was the monster but it turns out that the girls were also as monstrous as him.
"I will teach you the real technique and you will be staying here all night with me. Don't worry, I will inform your teacher so that no one bothers thinking where you went." Tsunade spoke with a dangerous smirk on her face.
She tried to scare the three of them with the same face she scares her brother but to her bewilderment they did not even bat an eye to her and shrugged.
During the night Tsunade passed all of her insights to the trio while trying not to overwhelm them. She seemed to have once again underestimated the learning potential of the kids as they absorbed everything she taught them like a sponge.
Their talent was far greater than anything she has ever seen.
After she was done explaining everything, all that was left for them was to practice the real thing. She found herself curious about the boy's limits. Everytime she think he won't shock her anymore, she get shocks after shocks, each bigger than previous ones
After thinking of something she looked at Tsukimi and asked.
"Akihiko-kun, what will you do after the war ends?"
Hearing those words, everyone stopped their actions and turned to look at Tsunade.
"Why the sudden curiosity?"
"Nothing, I was wondering what your dreams are. What do you want to do after everything ends."
"Dreams huh? If you are asking what I would do just after the war ends, that is to take a break for a while."
Tsunade was a little surprised but waited for the boy to continue.
"But my dream is to spend eternity with my wives. I don't want a big family, I just want a happy family."
His words seemed to have touched the girl's hearts and they hugged him. Tsunade just stared at the boy, her thoughts unknown to anyone.
"So what would you do after the break is over?"
"I would become a teacher at the academy."
"What??!!"
