Tsunade

With a rare stretch of time he could arrange freely, Hyuga Mirai felt much lighter after settling matters with Hyuga Kiyomi.

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.

They claimed the 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 come looking for trouble.

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

Ever since joining the mission squad, he had not been here for a long time.

"Is that Mirai-kun? You finally came back. Long time no see!"

"Asano-san, it has 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 just gotten busy lately, so your return is a huge help."

"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 established at Konoha Hospital before: helpful, hardworking, intelligent, eager to learn, and so on.

As long as someone asked Hyuga Mirai for help, he would basically never refuse. This had also earned him a good reputation throughout 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 had suddenly increased quite a bit lately, and they were so busy that they used a great deal of Chakra almost every day. If Hyuga Mirai could return as a Medical-nin, it would truly ease their burden considerably.

Before Hyuga Mirai left, Nakano had already had nothing left 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 apologetically. "Sorry, Senior Nakano. I came this time to borrow the Laboratory. I applied to Hokage-sama for an authorization slip."

"Ah, I still maintain that if you focused on Medical Ninjutsu, you could absolutely become Konoha's Medical Saint, just like Tsunade-sama."

Nakano shook his head regretfully. Back then, he had wanted to keep Hyuga Mirai at the hospital, but the Hyuuga Main House had wanted to transfer Hyuga Mirai away, and Nakano had no way to stop them.

"The Laboratory? If I remember correctly, 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 upon hearing this. If that was the case, then he really was unlucky.

Hyuga Mirai thought for a moment, then asked, "Is Tsunade-sama still at Konoha Hospital?" Around this time, she should be about to leave Konoha.

Nakano scratched his head. "Someone saw Tsunade-sama come in this morning, so 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. Therefore, even though she drank during work hours, no one dared say anything about it.

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 the door open and walked in. The first thing they saw was a table covered in empty liquor bottles, all apparently drained. A blonde woman with twin ponytails sat behind the desk, resting her flushed, drunken face against one hand.

She was exceptionally beautiful, and 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, who previously worked at the hospital as an apprentice doctor. He brought Hokage-sama's authorization slip today and would like to use the Laboratory."

After entering, Nakano respectfully explained 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 drowsily, "The Kid beside you wants to use the Laboratory?"

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

Tsunade seemed very reluctant 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..."

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

But he had no intention of arguing with a drunk, especially when that drunk was a powerful woman.

Hyuga Mirai only wanted to borrow Konoha Hospital's Laboratory, verify his ideas through experiments as soon as possible, and gain no small 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 abruptly 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 inwardly, then gently reminded her, "Tsunade-sama, this is the approval document..."

Bang!

Tsunade slapped the desk 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 merit."

What he 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 long been feeling stifled. This was precisely when she would make trouble for no reason.

"Then hurry up and tell me what you want to borrow the Laboratory for, Kid."

Ugh!

Hyuga Mirai thought for a moment, then formed hand seals and directly gathered 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 usable to make Healing Tags through seals..."

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

"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 thought of recently. Yet none of that was his main goal. What he truly wanted to study was his own Byakugan bloodline, to seek a way to remove the Caged Bird Seal through genetic research.

But Hyuga Mirai's words had already left Tsunade, her face flushed from drink, staring blankly.

This Kid looked about the same age as Shizune, yet his medical skill had already reached this level?

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

As for the other questions, they were essentially 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 had barely lasted 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?

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

"Here's the key. Leave!"
