Infinite Upgrade Technique of the Heavens

With the rise of the Third Generation Sarutobi Hiruzen, Konoha Village began to quickly restore its strength. New leaders took office in various departments.

However, these have nothing to do with Chen An. Chen An has been treating patients in the hospital and studying new ninjutsu.

Chen An, who had just returned to the office that day, had his door knocked gently.

"Come in!"

Chen An said to the person knocking on the door without raising his head.

Hearing Chen An's answer, the door was gently opened, and a familiar face appeared in front of Chen An.

"Tsunade, what do you have to do?"

Chen An looked at the person who came in and found that it was Senju Tsunade, so he asked curiously.

"Good day, um... are you tired from work? Do you need my help?"

Senju Tsunade asked embarrassedly.

"Not tired, I just started working today, how can I be tired?"

Chen An stared at Tsunade Senju curiously, wondering what exactly was going on with Tsunade Senju?

"Do you need to eat? I'll buy it for you."

Hearing Chen An say no, Tsunade Senju added anxiously.

"It's only eight o'clock now, it's not time to eat yet."

Chen An looked at Tsunade Senju with amusement and said helplessly.

Chen An knew that Tsunade Senju must have something to ask him, but she was embarrassed to ask him. It happened that he had a need, so he could give Tsunade Senju a way out.

"Okay, Tsunade, just tell me what you need. I will definitely help you if I can."

Chen An interrupted Tsunade Senju's mouth and said helplessly.

"Well, it's nothing, actually. I mainly want to learn some medical ninjutsu from you."

Hearing Chen An's words, Tsunade Senju hesitated for a long time. Finally, she spoke weakly.

"What do I think it is? If you want to learn, you can just ask. And although we are not particularly close relatives, we can at least be considered friends. You can't even bring yourself to talk about such a small matter. Don't you underestimate me a little bit?" Chen An laughed and helplessly took out a scroll from his bookcase and handed it to Tsunade. "This is all my medical ninjutsu, all recorded in it, you can take it and learn it. "

Chen An smiled and handed the scroll to Tsunade Senju.

The scroll in front of him not only contains the Chakra Scalpel and Palm Fairy Technique, but also the S-level medical ninjutsu creation and regeneration developed by Tsunade Senju based on the passiveness of Hashirama Senju.

However, this one records Tsunade Senju's original ninjutsu, which requires Yin Seal to store chakra.

And the version created by Chen An himself is activated with his own Dantian as the core.

Tsunade Senju took the scroll and looked at Chen An in disbelief.

Suddenly, Tsunade Senju thought about it and put the scroll down embarrassedly.

"Good day, I can't take your technique for nothing. How about this, think about what ninjutsu you need, and I can let Grandma Mito give it to you. "

Tsunade Senju looked at Chen An with a serious face.

"Is that so? Then I won't be polite. "

Hearing what Tsunade Senju said, Chen An was secretly delighted, and looked at Tsunade Senju with a bright expression and said.

"No problem, you said I would go back and ask Grandma Tsunade."

Tsunade Senju looked at Chen An firmly and said very seriously.

"I want to obtain the summoning technique, the summoning scroll of Shikotsu Forest and the Flying Thunder God Technique created by Master Tobirama Senju."

Chen An looked at Tsunade Senju with a smile and said.

"Okay, I'll go back and ask Grandma Mito."

Hearing Chen An's conditions, Tsunade Senju turned around and wanted to leave, but was pulled by Chang'an.

"Don't go, take this ninjutsu scroll back. Let Master Mito Uzumaki take a look and see if it's worth these two ninjutsu. "

Chen An smiled and stuffed the scroll of medical ninjutsu into Tsunade Senju's arms, and said to Tsunade Senju

"Okay, thank you, good day"

Tsunade Senju couldn't avoid it, so she had to take Chen An's medical ninjutsu scroll and bowed to Chen An.

Watching Tsunade Senju leave, Chen An sat on the chair with satisfaction.

I had always wanted to study the method of mutual spiritual communication between people in the summoning technique.

But Chen An found that this method seemed to be unable to make a summoning scroll.

It can only be teleported between two people.

But if the entire Hyuga clan teleports to each other, it will be more troublesome.

Chen An wanted to see how the summoning clan joined the entire family and how to summon according to the amount of chakra paid by the summoner.

Tsunade Senju returned to the Senju clan with the medical ninjutsu scroll.

"How is it? Xiao Gang, how are you doing?"I wish."

Looking at Tsunade Senju coming back with a scroll, Uzumaki Mito said to Tsunade Senju with a smile.

"Grandma, I didn't take Ri'an as my master, but he gave me all the scrolls of medical ninjutsu. He said he wanted to exchange them for the Flying Thunder God Technique and the Summoning Scroll of the Wet Bone Forest."

Tsunade Senju carefully placed the medical ninjutsu scroll in front of Mito Uzumaki and said to Mito Uzumaki.

"Oh, really? Then let me see. Is this little guy's medical ninjutsu enough to exchange for two S-level ninjutsu? "

Uzumaki Mito curiously picked up Chen An's medical ninjutsu scroll and said to Senju Tsunade with a smile.

As the medical ninjutsu scroll was opened, Uzumaki Mito carefully checked the medical ninjutsu recorded in it.

The first two medical ninjutsu, whether it was the chakra scalpel or the palm fairy technique. Uzumaki Mito didn't care. With her ability, she could still create two A-level medical ninjutsu with some time.

But when Uzumaki Mito saw the creation and regeneration, her eyes suddenly lit up.

Because creation and regeneration are very suitable for her granddaughter Senju Tsunade.

"Xiao Gang, it seems that the little guy's ninjutsu is indeed worth the two S-level ninjutsu."

Uzumaki Mito put down the scroll in his hand and said to Senju Tsunade with a smile.

"Really? Grandma? Is this ninjutsu very powerful?"

Senju Tsunade looked at Uzumaki Mito in confusion and asked Uzumaki Mito.

"Yes, this ninjutsu is not only powerful, but also very suitable for you. "

Uzumaki Mito nodded and said to Senju Tsunade.

"Then should I go to my second grandfather's study to get the summoning scroll and the Flying Thunder God Technique?"

Senju Tsunade said to Uzumaki Mito excitedly.

"No need, you, just start learning these two ninjutsu honestly, grandma will help you, I hope you can learn it as soon as possible."

"You don't have to worry about ninjutsu, grandma will give it to Hinata Rian tomorrow and thank the little guy."

Uzumaki Mito shook her head and denied the decision to let Senju Tsunade go to deliver the ninjutsu.

I hope Senju Tsunade can learn all the medical ninjutsu developed by Chen An as soon as possible.

"Okay, grandma, I know."

Senju Tsunade quickly put away the medical ninjutsu scroll and ran to her room.

She wanted to see how powerful the ninjutsu invented by Hinata Rian was? Even her grandma praised it.
