Early the next morning, Mizuki came to the flower shop, arranged things in the shop, asked Haruno Sakura to help look after the shop, and then walked towards the Hokage Building.

It was too early, and apart from a few busy staff members, there were not many people in the building. Shuimu knocked on the door of the Sandai office.

"Come in."

Shuimu pushed the door open, then walked forward, bowed and said, "Third-generation master, I am here."

"It's Shuimu. You came quite early." Sandai stopped his work and looked up and said.

"You've worked earlier and harder than me. May I ask what you want me to do?"

"I have something to ask you~" Sandai lit up his pipe, took a puff and said, "Do you remember the potion you gave to Gekkou Gale and Yamashiro Aoba to use last time in Wave Country?"

"Yes." Shuimu affirmed.

"Did something happen that I'm not aware of?"

"Don't worry, I'm just asking about the progress of the medicine research." The third generation said kindly.

"There has not been much progress in new development, but we have made some unexpected discoveries about the efficacy and usage of the medicine." Shuimu was relieved to hear that there was no accident with the medicine.

"Oh? Tell me more about it." The third generation seemed very interested in this.

"Yes." Shuimu also decided to explain the general situation. He would definitely not talk about the most fundamental effect. After all, it was too shocking, and he did not have the strength to guarantee that he would not encounter unexpected troubles.

"Although the improvement of the drug's efficacy has not had any effect yet, the function of this drug has been clarified. For ninjas on the battlefield, it is a good healing medicine and supplement. Generally, as long as sufficient physical strength and sufficient chakra are guaranteed, the damage to the human body is not too great. Through medical ninjutsu, most people can recover. The only trouble is that it will overdraw the activity of cells. Using too much will greatly reduce lifespan, and the side effects of this drug will gradually accumulate. At present, no suitable way to replenish vitality has been found."

"Can you be sure that there won't be any side effects in the short term?"

"Yes, this should be confirmed."

"But the village did some experiments with the potion in Yamashiro Aoba's hands, and it seems that the results were very bad~"

"I guess the village has never conducted human experiments?" Mizuki didn't hesitate, "Or maybe they haven't conducted experiments on ninjas?"

"Hmm?" Sandai's face suddenly darkened after hearing this. "Could it be that you have done experiments with ninjas?"

"You misunderstood. The problem we found is that the effects of the drug on ninjas are unexpectedly good because of the huge difference between the effects of the wild animal experiments and the actual use." Mizuki explained, "So I think it may be the effect of chakra, and the actual effect of the drug also confirms my judgment."

"Is that so." The third generation thought about it. It seemed that Moonlight Gale, Yamashiro Aoba and Mizuki all used potions, but the possibility of them surviving at the same time was compared with the experimental data of wild animals. It seemed a little too lucky.

"What is the production volume of the medicine?"

"It's extremely troublesome to manufacture, and the cost is too high. I guess it can only be used as a desperate trump card now. Although it is much more effective than conventional medicines, it can't completely eliminate side effects, and it can't be mass-produced, so it's not cost-effective."

"How much medicine has been discharged so far?"

"Except for what Gekkou Hayate and Yamashiro Aoba have, only my fiancée Chie Tsubaki and I have it."

"Chie Tsubaki? Is she from the Sealing Class?"

"Yes." Shuimu affirmed.

"Okay, that's it. You can go down first. Don't let anyone know what happened today."

"I understand, Lord Sandaime." After saying that, Shuimu stepped out.

Watching Mizuki go out, the Sandai turned sideways and pulled out the bottom drawer on the right, revealing a large tube of green potion, which was the leftover from the experiment that he had taken back from Yamashiro Aoba.

"With this, I feel more confident, but I hope I won't need it!"

Thinking so, the Sandaime put away the potion and put it into his ninja tool bag.

Mizuki left the Hokage's office without thinking too much. It probably didn't matter to him anyway. If he had to supply the universal potion himself, he could just sell it at a high price. Anyway, this thing was exclusive to the market, and he could decide how much it cost. If he wanted to learn the configuration, forget it. No one could learn it anyway. Even if Orochimaru didn't have the basic data, he didn't know when he would be able to crack it. By then, who would be afraid of whom?

Shuimu walked leisurely to his own flower shop and bought a few strings of dumplings for breakfast. He didn't care about his image at all and ate them while walking.

When I arrived at the flower shop, I found that there was one more person inside.

"Why are you here? Do you want to buy flowers?" Shuimu asked.

The person who came was none other than Yamanaka Ino.

"Teacher Mizuki, I'm here to work?" Yamanaka Ino said respectfully.

"No need, we have someone." Shuimu refused directly. Just kidding, one person is already a headache, two people, especially two girls, will be noisy. "Besides, isn't your family also a flower shop? Why are you coming to my place?"

"No way, Mr. Mizuki, I noticed that this store has not been open for several days. It is obvious that no one is in charge."

"I just overslept. What's it to you? Besides, there are people in the store now."

"You mean Sakura? She's not a temporary worker, she's here to learn ninjutsu?"

"You don't understand. Occasionally, you need to combine work and rest. Besides, it can also train her character. Do you know what character is? It is perseverance. You have to believe in the teacher's integrity and will not mislead the students."

"Ino, don't argue. I told you I don't need your help." Sakura heard what they said and hurried over to smooth things over. "Teacher Mizuki, please don't be angry. Ino means no harm."

"I know. I don't have the money to hire anyone. You're welcome to come work for me in a month, but not now."

"I don't want any money, I just come to help."

"Hire you." If it doesn't cost money, then don't refuse it.

"Mr. Mizuki, you just..." Ino wanted to continue arguing, "Eh? What did you say?"

"I said I'd hire you. Why would you come out to work if you have hearing problems?"

"You're hired right away?" All the words Ino had prepared were of no use.

"What are you dawdling for? Why don't you go to work? Don't you want to do it anymore?"

"I'll get to work right away." Ino hurriedly began to tidy up the flower shop.

"You guys go ahead and do your work first. I'll go out for a walk and come back to check later." Why not go out for a walk while you can be lazy? You've been feeling very cooped up these past two days.

Just after Mizuki left, Yamanaka Ino made a success gesture to Haruno Sakura.

"I said it's okay, done."

Sakura shook her head, "You won't be able to help much if you stay here. I think it's good for Mizuki-sensei to be here."

"I'm not trying to help you. I'm just afraid that you'll lose too badly. Wouldn't that make me look even more incompetent?"

"Let's not talk about this anymore. Teacher Mizuki will come to check the homework this afternoon. You should go ahead and do your work."
