Hearing Tsunade's words, Mizuki immediately felt that something was wrong. He was being thought of before his injury healed. He had been doing missions continuously during this period of time, and he was finally wounded heroically. He didn't even have a vacation, which was really bad.

"Well..." Shuimu said with a gloomy face, "I want a vacation for a while..."

"No." Mizuki was interrupted by Tsunade before he could finish.

"Listen to me, I have my reasons."

"No reason is enough. Look at the other ninjas. Aren't they all having a hard time?"

"Well, I'm getting married, is that not okay?" Facing such a strong Tsunade, Mizuki had to smile awkwardly.

"Huh?" Tsunade was also choked by hearing the unexpected words of the master, "This is the reason?"

Tsunade thought for a while with a headache and said, "Although it's not a good time to take a vacation, especially for a jonin, I'm not unkind. Something festive can also change the atmosphere of the village that has been so lifeless recently. Tell me, how long do you want to take a vacation?"

"One month, okay?" Shuimu said tentatively in a low voice.

"No, stop dreaming." Tsunade ruthlessly strangled Mizuki's whimsical ideas.

"Then let's do half a month, no less."

"It's too long, give me a week at most." Tsunade cut Mizuki's number in half.

"A week is too short, at least ten days, right?"

"No, just one week, forget it if you don't want it."

Mizuki was still trying to bargain with Tsunade, but Tsunade directly extinguished the spark of Mizuki's fantasy.

"One week is enough. It's enough."

"Come to me later that week. There are a lot of tough things that need you to deal with."

"A week? I haven't started preparing yet. You see, I'm injured now. Should I treat my injury first and then start taking a vacation?"

"What are you asking for if you're not prepared? It will take about three or four days for you to recover. Are you going to stop until you have ten days off?"

Tsunade said, rubbing her forehead with a headache.

"Isn't this a legitimate reason? We can't send the wounded to do the mission."

"Okay, ten days is ten days." Since that was the case, Tsunade stopped pestering him. "But after ten days, I hope you won't have any more reasons to complain."

"Okay, I'm famous for keeping my word." Shuimu patted his chest and promised.

"That's it, then."

After finishing her digression, Tsunade handed a scroll to Mizuki, and then said solemnly: "This is the legacy of the Uzumaki family that I told you about. Would you like to take a good look at it?"

Shuimu took it, touched the cover which was made of unknown material, then spread it out and took a look.

When he saw the first name in the list, even Shuimu, who had been prepared, was shocked.

Then, Shuimu closed the scroll, took a deep breath, and said, "This is too valuable..."

Tsunade shook her head, "This thing has been in the village for years, but ever since Uzumaki Kushina died, no one understands these things anymore."

As she spoke, Tsunade sighed, as if she remembered something from the past, and looked thoughtful.

After a moment's silence, Tsunade continued, "The only known orphan of the Uzumaki family, Uzumaki Naruto, obviously doesn't seem to be able to understand this thing. The sealing techniques used in the village are almost all passed down from a long time ago. Since the death of the Fourth Hokage, there hasn't been a ninja who is proficient in sealing techniques. You are the first one who can innovate and make achievements in this area in the past ten years. Therefore, it is appropriate to hand it over to you."

"Okay, I'll take it then."

Since that's what she said, it means Tsunade has thought it through clearly, so Mizuki will no longer delay it. Moreover, at this time, she really needs these things to expand her knowledge base. If she relies on her own research, the accumulation is still too slow.

"Well, take a good look at this, it might be of great help to your injury."

"I'll try this. Although I haven't seen the details yet, from my understanding, it seems to be completely different from the problem of my vitality that I need to solve."

"So I'm saying that even if you are very good at using medical ninjutsu, you are still not a qualified medical ninja. Even an ordinary rookie who can't even use a chakra scalpel may have more imagination than you in this regard."

Tsunade seemed to disagree with Mizuki's words.

Although he was a little unconvinced, Mizuki also knew that what Tsunade said was not wrong. After all, everyone has their own expertise. Mizuki looked down on the strength and level of those medical ninjas, but it could not change the fact that he was actually an outsider.

When Mizuki remained silent, Tsunade continued, "I'm sure you haven't seen this jutsu before, but you must have heard a lot about it."

"Yes." Mizuki nodded in confirmation, "For someone like me who is interested in sealing techniques, this kind of sealing technique that is so powerful that it can even restrict the tailed beasts is something I have long wanted to see."

"The Diamond Seal is indeed very famous in some circles, but with the annihilation of the Uzumaki family, it has not been circulated for a long time."

"I know, but this kind of sealing technique based on the Uzumaki family's powerful vitality and special physique, ordinary people simply can't withstand it, right?"

"You've already guessed a lot before you even saw it. I'm increasingly feeling that handing it over to you is the right choice."

Tsunade said appreciatively, "You are right. The word that is circulated outside about the Diamond Seal is to use the exploded chakra to form a sealing chain to restrain others or even capture the tailed beasts. Although this powerful sealing technique is rare, it is not unique, but most of them require multiple people to use it at the same time, and there are great restrictions. Like the Diamond Seal, it is extremely rare that only one person can use it freely."

"There shouldn't be such a good thing."

"Of course there is a price. No matter how much ordinary chakra explodes, using the limited chakra of a human body to restrain a tailed beast whose chakra is much higher in 'quality' and 'quantity' than one's own, it is a bit incredible, isn't it?"

“That’s really strange.”

"Although I am not very clear about the details of this technique, as a secret technique unique to a family, it is almost inevitable to develop ninjutsu around the powerful vitality unique to this family."

Mizuki agrees with Tsunade on this point. The most typical example is the Hyuga family. Almost all of their techniques are developed to make full use of the Byakugan's strengths. The Gentle Fist can be said to be born for the Byakugan.

At this point, Shuimu roughly understood that the King Kong Blockade was just a reference. Without the system of the Uzumaki clan, it would probably not be suitable for him to copy it completely. The key is to find the value points that he needs in it.
