Qing Yu originally thought that someone who overtrained his body was not easy to find. Even if someone was willing to act as this little guinea pig, it would take a certain amount of time to use up all his physical strength.

However, the fact did not make them wait any longer, and soon someone brought the guinea pig.

And this little guinea pig is none other than Matt Kay who regards Kakashi as his lifelong rival and best friend!

Qing Yu was stunned for a moment, obviously not expecting this result.

But after thinking about it, he needs to find someone who is "overtrained" and "overdrawn", does the whole Konoha fit better than Kai?

And judging from Kai's thoroughly soaked clothes, this guy must have undergone hellish special training before he was found!

In addition, don't underestimate Kai in this period. Although Kakashi graduated at the age of 5 and became a legend, Kai is not much inferior. He graduated from the ninja school at the age of 7. It took three years, only one year less than Kakashi. .

Although he is still only a Chunin at the age of 14, his strength has been recognized by many people, and it may not be long before he can rise to the level of Junin like Kakashi.

And Qingyu probably still remembers that Kai became a real Jōnin when he was 16 years old. This time was only 4 years later than Kakashi, which is already a very proud achievement among his peers!

Then it is worth mentioning that, among the future Konoha Twelve Strong, the first one to jump to Jōnin is Neji, who is only 15 years old...

So, Neji, you died so miserably!

"Now there is a task that requires your cooperation. It may have a certain impact on your body. Bad effects cannot be ruled out, but there is a high probability that it should be a good one. It doesn't matter if you don't want to. This is not a mandatory task." Minato looked at Kai and said gently.

If you change someone else, you will definitely have great concerns at this time.

But Kai was different. As soon as Minato finished speaking, he gave a thumbs up, showing his white teeth, and said with a hearty smile: "Leave this task to me, I am very confident in my body!"

Minato rubbed his temple helplessly, he knew that would be the result.

But he wasn't too worried, after all, Mikawa Kamijin wouldn't let Aoyu fool around, and Aoba had used it himself, and it was many times, so there was a high probability that there would not be any danger.

Then... just try it!

As a result, everyone moved directly to another room, which had already been arranged as required.

"Lord Hokage, what do I need to do? Shatter this barrel?"

As soon as he entered the door, Kai started to move his body with some enthusiasm. You must know that he has always wanted to go to Anbu to help Kakashi, but Hokage-sama has always disagreed. This undoubtedly makes him regretful and feels that he has lost a lot in life. fun of.

"No, then you need to take off your clothes and stay inside, um, at least half an hour."

Kay, who is not afraid of even the sea of ​​​​swords and flames, became a little awkward and stunned for the first time after hearing that he needed to take off his clothes!

"Take off, take off your clothes!?"

"Yes, someone recently found a recipe for a medicated bath, which can repair dark wounds in the body, improve cell activity, and replenish physical energy consumption. In addition to this, there are many other effects. Although some people have tried it, they still need more. Different people are tested, and there may be some side effects, so you still have the opportunity to refuse.”

Minato seemed to have the same idea as Mikawa Kaminin, and didn't want to put too much pressure and trouble on Aoba, so he didn't mention who provided the prescription, and the test was completely voluntary.

But Kai was not frightened, but looked at the barrel with fiery eyes.

Repair body dark wounds?

Increase cell viability?

Supplementary physical exertion?

Isn't this a medicated bath tailored just for me!

If this thing works, doesn't it mean that he can use it for a few more hours of exercise every day? even more! ?

As expected of a training madman, the first thing that comes to mind is to spend more time practicing hard.

And it's not that Kai doesn't know that his extreme exercise method will cause damage and overdraft to his body, but he can't help it.

Because in other respects, he has absolutely no corresponding talent!

Only hard work and sweat will not deceive him!

So he can only go to the dark one way, overdraft the future, in exchange for the present!

He didn't want to be a jainin for the rest of his life!

So... bang!

Regardless of the presence of outsiders, Kai took off his clothes at the fastest speed, and then jumped into the wooden barrel.

The water temperature is about 45 degrees, which is a little hot, but it is more comfortable for him!

"Is it enough to keep soaking like this?" Kai asked embarrassedly, leaving only his head on the water.

At this time, Minato looked at Qingyu with a gentle smile, meaning that you can come in person, and you don't have to be afraid that someone will intercept the remaining powder and push it back.

At this time, Qing Yu was also infected by the goodwill of the fourth generation, and the worries in his heart were relieved a lot.

So he directly handed the medicine packet to Mikawa Kaminin, "Just pour it all in."

Mikawa Kaminin was even more unequivocal. After receiving it, he immediately poured all the black powder into the wooden barrel in front of everyone, and then without thinking about it, he threw the remaining packaging residue directly into the side for boiling water. inside the stove.

He did so not only to avoid suspicion, but also to express his attitude.

This made Qing Yu look at him with a softer gaze, and even Minato looked at him with admiration.

Then, the hot water that was poured into the medicinal powder turned pitch black almost instantly, and the color was extremely terrifying just by looking at it.

And at the same time, Kai also seemed to feel the effect of the medicine, and his expression changed, very serious.

"How do you feel now?"

"The pain is like a needle stick, but it can be endured." Kai replied truthfully.

Minato nodded silently. Regarding this 'side effect', he had already heard Qing Yu himself explain it a long time ago, so he didn't make a fuss.

So time is waiting, slowly passing...

At first, Kai was a little uncomfortable, but as time went by, he not only got used to taking a bath in front of others, but also got used to the pain caused by the medicated bath, and slowly he could feel a warm current. He began to walk around on him, and the places where the dark wounds were more serious usually became hot and hot, as if they were on fire!

Maybe it's really useful!

Kai's eyes could not help flashing a trace of excitement.

In about thirty minutes, the black medicinal liquid in the wooden barrel had begun to become transparent again, which meant that the medicinal effect had almost dissipated, and most of it had completely penetrated into Kai's body.
