Tsunade

It was rare for him to have some time he could arrange freely. After settling matters with Hyuga Kiyomi, Hyuga Mirai felt much lighter.

If possible, he truly did not want to be a guard for the Main Family. There were no benefits at all, only a whole pile of trouble.

The so-called benefit was guidance in Gentle Fist training, but that merely meant training alongside the Main Family. As for the Main Family's secret Ninjutsu, there was no way a Branch Family guard could ever learn them.

Hyuga Mirai practiced Revolving Heaven in private and had never displayed it before anyone else. Otherwise, the Main Family would definitely make trouble for him.

After receiving Sarutobi Hiruzen's approval slip, Hyuga Mirai packed up briefly and headed to Konoha Hospital.

Ever since joining the Mission Squad, he had not come here in a long time.

"Is that Mirai-kun? You're finally back! It's been so long!"

"Asano-san, it has indeed been a while. The Captain gave us a short break recently, so I came back to take a look."

"Mirai-kun, you're back? That's wonderful. The hospital has gotten busy lately, so you've really come at the right time."

"Haha, is that so?"

After Hyuga Mirai returned to Konoha Hospital, many people greeted him warmly when they saw him.

That was all thanks to the image Hyuga Mirai had built for himself at Konoha Hospital: helpful, diligent, clever, eager to learn, and so on.

As long as someone asked Hyuga Mirai for help, he would rarely refuse. That had earned him quite a good reputation at Konoha Hospital.

"Mirai-kun, are you coming back to be a Medical-nin?"

Upon hearing that Hyuga Mirai had returned, Doctor Nakano happily rushed over to ask. The number of injured people had suddenly increased recently, and they were so busy that they used a great deal of Chakra nearly every day. If Hyuga Mirai returned as a Medical-nin, it would truly ease their burden.

Before Hyuga Mirai left, Nakano had already had nothing more to teach him. After so much time had passed, Nakano did not believe that, with Hyuga Mirai's talent, his Medical Ninjutsu had not improved at all.

Hyuga Mirai smiled awkwardly. "Sorry, Senior Nakano. I came this time to borrow the Laboratory. I applied to Hokage-sama for an approval slip."

"Ah, I still insist that if you could focus on Medical Ninjutsu, you would definitely become a Medical Saint of Konoha, just like Tsunade-sama."

Nakano shook his head regretfully. He had wanted to keep Hyuga Mirai at the hospital back then, but the Hyuuga Main House had wanted to transfer Hyuga Mirai away, and Nakano had been powerless to stop it.

"The Laboratory? As I recall, only Tsunade-sama and the Vice Dean have keys. But the Vice Dean left Konoha to purchase medicinal herbs in the Land of Fire."

"No way!?" Hyuga Mirai froze at those words. If that was the case, then he really was unlucky.

Hyuga Mirai thought for a moment before asking, "Is Tsunade-sama still at Konoha Hospital?" Around this time, she should be close to leaving Konoha.

Nakano scratched his head. "Someone saw Tsunade-sama come in this morning. She should still be here. I'll take you to check."

Quite a few people at Konoha Hospital knew that Tsunade drank while on duty. However, she was one of the Sannin and the Medical Saint who had established Konoha's medical system, so no one dared criticize her for drinking during work hours.

Then, led by Nakano, Hyuga Mirai followed him to the Dean's office on the top floor.

Knock, knock!

"Tsunade-sama?"

Nakano knocked twice and called out. Only after a long while did a reply of "Come in" drift out from inside.

The two pushed open the door and entered. The first thing they saw was a table covered in empty wine bottles; they appeared to have all been drained. A blonde woman with twin ponytails sat behind the desk, propping up her flushed, drunken face with one hand.

She was exceptionally beautiful, and combined with her captivating figure and astonishing strength, Tsunade could almost be called the most popular of the Sannin.

Hyuga Mirai merely glanced at her before withdrawing his gaze and standing obediently behind Nakano.

"Tsunade-sama, this is Hyuga Mirai. He previously served as a trainee physician at the hospital. Today, he brought Hokage-sama's approval slip and wishes to use the Laboratory."

After entering, Nakano respectfully explained the matter to Tsunade. However, Tsunade seemed to have drunk too much. Her gaze was unfocused, and she even let out a drunken hiccup.

After a while, Tsunade replied groggily, "The kid beside you wants to use the Laboratory?"

"Yes, Tsunade-sama. Hokage-sama has already approved it."

Tsunade seemed very unwilling to hear Sarutobi Hiruzen's name. She curled her lips and muttered as she took out a key from the drawer. "That old man is really muddleheaded, letting a kid use the Laboratory whenever he wants..."

Although Tsunade's voice was quiet, there were only three people in the room, so Hyuga Mirai heard her clearly.

However, he had no intention of arguing with a drunkard, especially one who was a powerful woman.

All Hyuga Mirai wanted now was to borrow Konoha Hospital's Laboratory, verify his theories through experiments as soon as possible, and gain a significant boost to both his strength and reputation if he succeeded.

However, just as Hyuga Mirai reached out to take the Laboratory key, the flushed Tsunade started causing trouble again.

Just as Hyuga Mirai was about to take the key, she suddenly pulled her hand back and muttered, "kid, what do you need the Laboratory for? Do you know how valuable the equipment inside is?"

Seeing this, Hyuga Mirai sighed helplessly in his heart before quietly reminding her, "Tsunade-sama, this is the approval document..."

Bang!

Tsunade slammed her hand against the table and shouted, "You little brat, are you using the Third Hokage to pressure me?"

"Not at all, Tsunade-sama. I merely want to use the Laboratory. This opportunity was exchanged for with mission merits."

What Hyuga Mirai meant was: stop making trouble. This was an opportunity he had earned by risking his life. As a senior, did she really have the nerve to make things difficult for a junior?

Unfortunately, Tsunade was drunk, and she had been feeling stifled for a long time. This was precisely when she was liable to make trouble for no reason.

"Then hurry up and tell me what you're borrowing the Laboratory for, kid."

Sigh...

Hyuga Mirai thought for a moment, then formed hand seals with both hands and directly condensed Yang Release Chakra in his palm.

"While on a mission, I suddenly thought that since Fire Release Chakra can be made into Exploding Tags through Sealing Technique, Yang Release Chakra should also be able to be made into Healing Tags through sealing..."

"At the same time, Yang Release Chakra can directly stimulate cell division to heal wounds. Then is it possible to store Yang Release Chakra in vital areas beforehand, so that once injured, it will be released to heal the wounds..."

"Chakra originates from energy secreted by cells. There should be a way to directly store Yang Release Chakra within cells and control division and regeneration..."

Hyuga Mirai spoke steadily, laying out all the questions he had recently considered. However, those were not his main goal. What he truly wanted to research was his own Byakugan bloodline, using genetic research to find a way to remove the Caged Bird Seal.

Yet Hyuga Mirai's words had already left the flushed Tsunade stunned.

This kid looked about the same age as Shizune, yet his medical expertise had already reached such a level?

Healing Tags... thinking about it carefully, it really was possible. Yang Release Chakra was more stable than Chakra of other attributes, and with Sealing Technique, it might truly be possible to preserve it.

As for the other questions, they were practically the prototypes of her two S-rank Ninjutsu: the Yin Seal and the Strength of a Hundred Seal.

And this kid had casually used the Mystical Palm Technique. Had she been out of touch with village affairs for so long that she did not even know such a medical genius Ninja had emerged?

"Kid, you..."

The interest rising in Tsunade's heart lasted only a few seconds before she dismissed the thought herself.

She was about to leave the village. Why was she even thinking about taking on a disciple?

At that thought, Tsunade lost all interest. She waved a hand and tossed the key over.

"The key is yours. Leave!"
