contract with Katsuyu

Mune was in the forest again, in his hand a medium-sized rasengan was running.

"Interesting, my Rasengan mastery is good, but I still feel like I can't put wind chakra into it, too soon to think about Rasenshuriken" Mune

Mune didn't fear the physical damage Rasenshuriken could do to the body, he could easily regenerate cells, but for some reason, he always thought he would fail if he tried to insert wind chakra to rasengan

"Maybe it's not that simple, probably my understanding of the nature of wind chakra is low, I'll ask mom" Mune

Mune then left the forest and went to the hospital

Mune didn't know he was being monitored by an old man in a crystal ball

"Interesting, his rasengan is getting better, Minato didn't teach him, but he taught himself, a genius" Sarutobi

Sarutobi smokes his pipe, he was sitting in the chair watching Mune

"Not only his ninjutsu, but his medical jutsu are of the highest level according to Tsunade, too bad he doesn't have much interest in ninja life."

"But I don't think he will have a choice, many high level ninjas are complaining to me, his children are going to war while the greatest genius is still in the academy, I will have to promote him by force even though he is from the Senju clan , he needs to contribute " Sarutobi

While Sarutobi was still meditating, an ambu ninja entered the office.

"Hokage sama, an urgent message from Minato, an accident happened" said the ambu

Sarutobi made a horrible face as he read the letter

-----------------------------

Konoha Hospital

When Mune walked into the office, Tsunade had a serious face.

"Son, I have a present for you" Tsunade then took out a parchment

Mune then took the scroll, it was a Katsuyu Summoning Scroll

"Thanks mom, I'm happy" Mune hugged his mom

Mune didn't lie, although Katsuyu has the lowest combat power, his importance is greater than snakes and frogs

Ability to heal, ability to transfer chakra, ability to transfer information and protect allies, by far the greatest support anyone can have, Katsuyu

"Don't be happy too soon, you must go to Shikkotsu Forest after putting your blood in, only with Katsuyu's approval can you officially sign a contract" Tsunade

"Don't worry mom, I'm cute, Katsuyu will love me"

Mune then put the blood on the parchment, he felt his body being pulled

Mune disappeared

After Mune left, Tsunade's face got angry

Tsunade learned from the Hokage that Mune should go do military service in the war, Tsunade almost fought Sarutobi

Only after the Hokage swore that Mune would just stay a medical ninja and away from the front lines was Tsunade forced to agree.

Tsunade hates war and hates even more that her son participates in it, but she knows that for Mune's future, they must remain in Konoha

Tsunade made many enemies in the second ninja war, if she was alone she would leave the village alone, but with her son, she will never risk

"My son, unfortunately I cannot defeat all these noble clans, you must live, I swear that if you die, I will destroy this damn village myself" Tsunade

Floresta Shikkotsu

Mune felt the environment change, he appeared in a beautiful forest

The leaves on the trees were not green but pale blue.

"Beautiful place" Mune says

"A beautiful place indeed" Mune hears a gentle voice

Finally he realizes it was the white mountain that spoke, Mune pays attention to the mountain and realizes it has eyes

The mountain was white and blue, it had a slug shape.

"Lady Katsuyu ?"

"Yes it's me hehehe" Katsuyu in her gentle voice speaks

Mune now understands why Tsunade can only summon 10% of Katsuyu's body, the size was definitely at least the size of a tailed beast

"so you are the young son of Tsunade sama, glad to meet you"

"Lady Katsuyu, I'm the one who's happy"

Mune chatted with Katsuyu for minutes

"Lady, answer a question, can you teach Senjutsu? Or only snakes and frogs can, sorry to be rude"

"Don't worry, first you must understand that Shikkotsu Forest is different from the frog mount and snake cave, the Shikkotsu Forest is much bigger, I'm not the only one to live here, of course I'm the strongest in the place"

Turns out Katsuyu is peaceful by nature, so she's not territorial, in the forest there are many "wise" races

"Unlike frogs and snakes, I am the only one of my kind, and yes I use senjutsu, but unlike snakes and frogs that attract senjutsu to the body, I attract and use fusion, from the energy of nature to mine. body, simply put, my huge body you are seeing is not made of flesh, but materialized natural energy "

"It's impossible for any other being to do this, of course, except for the Bijū that are more or less the same, but their energy is purer and stronger"

"Unfortunately, I can't teach my senjutsu technique, no one could survive" Katsuyu

Mune was amazed by what he heard, he thought if it would be possible to modify his body to make this possible
