The universal potion is actually a thing that tests the self-control of those in power. Tyrants and paranoids will often ignore the harm and use it as a weapon of conquest. Idealists will despise it for destroying human ethics, and things that break the code of conduct will always be unacceptable to conservatives.

Tsunade and Mizuki were right to use it as a strategic material. The huge cost of making and using the potion greatly limited Mizuki's ability to produce it in large quantities. Only the Ninja Village, the highest-level organization in the ninja world, could fully exert the effect of the almighty potion. Of course, its harm would be more obvious.

Seeing that Mizuki admitted his guess, Tsunade did not make any special statement and asked calmly: "Developing such a potion is not something that can be done in a short time, right? There are endless desperate moves and secret potions that overdraft life force, but a potion like yours that has such a powerful effect and can even create a complete copy is not so easy to do."

Shuimu replied: "My original intention was just to create a healing potion with outstanding effects. It was only later that I discovered the great value of potions in biological research."

Mizuki was not lying about this. In the beginning, he really only regarded it as a therapeutic potion with huge side effects. However, later he accidentally discovered that the potion was very sensitive to chakra, had a unique advantage in cell replication, and could effectively inhibit disordered mutations. Therefore, its value was more than just a therapeutic potion.

"Since you already know it so clearly, I guess you must have conducted a lot of experiments in private, right? Your strength has improved by leaps and bounds in the past few months, which should be due to its benefits, right? How to use this potion, I guess no one knows it better than you, the inventor..."

Facing Tsunade's question, Mizuki hesitated for a moment, but finally admitted: "Although there is no direct relationship, it did help me more. Without this potion, the improvement of strength would not be so smooth. So, there are indeed private human experiments. I don't deny it, but I have never actively harmed anyone for experiments."

Aside from Kotsubaki and Mizuki's own samples, the rest were either trophies or remnants of battle, and none were as unscrupulous as Orochimaru.

"Don't be nervous. I know very well if there are any bad human experiments."

Ever since she knew the effect of the all-purpose potion, Tsunade had secretly started to investigate Mizuki's background. Many details that Mizuki himself had not noticed were within the scope of the investigation. The first thing to do was, of course, to check the situation of the civilians and lower-level ninjas in the village to see if there were any signs of missing people in the past few months. Fortunately, it was just a false alarm.

"With the omnipotent potion, you don't need to go through the trouble and bloodshed of human experiments like Orochimaru did. If I hadn't known you would have had your bottom line, you would have been hunted down by the Anbu."

"Thank you for your kindness!"

Mizuki bowed and thanked him, speaking sincerely.

"You don't need to thank me. It's because you haven't gone astray yet. I won't do anything to you. But, as the saying goes, those who are good at swimming will drown, and those who are good at riding will fall. I hope you take care of yourself."

"I understand. I won't make it difficult for you."

Tsunade nodded, and then asked, "Has your potion-making method been spread out?"

"No!" Shuimu shook his head and replied, "The method is very complicated, so the output is not high. Even I don't have much stock. The production method is even more difficult to understand."

Even Mizuki used chakra, a universal tool, to simply and roughly extract the required substances to synthesize medicines. The biological and medical technologies in this world are still very simple and primitive. Not to mention polymerase chain reaction, etc., this advanced method of amplifying and replicating specific genetic materials, Mizuki himself does not understand it at all, and it is even more impossible for anyone in the ninja world to figure it out. The generation gap in technology is too huge, and science is almost becoming a magic. If you want to mass produce, Mizuki can only spread it through hand-to-hand teaching, and the difficulty of learning is also amazing. At least so far, even his own disciple Haruno Sakura has not touched the threshold. It is not easy to make a brain that plays with kunai and chakra understand and accept another academic discipline.

"The production method is difficult, so have you ever thought about the possibility of it being cracked?"

"Crack?" Mizuki was stunned, thought for a moment and then answered cautiously, "Although I think the possibility is small, but for ninjas, there is no such thing as absolutely impossible."

The carrier of Jūgo's cursed seal is a special biological enzyme produced by a bloodline limit. Since Orochimaru was able to crack it, copy it, and use it for himself, then cracking the omnipotent potion is not completely impossible. It's just that the possibility is not high without any clues.

"Is that so? Got it!"

Tsunade had tried to copy the potion before. As Mizuki said, it was possible to do it with the help of chakra. With Tsunade's own chakra control ability at the cell level, she did get some samples of the same potion, but the efficiency was so low that it was outrageous and completely impractical. It was like grinding an iron rod into a fine needle with a grindstone instead of a handy electric grinder.

"I have already taken this potion back as a banned drug. All the outflowing potions have been collected and sealed, so I hope to completely block the outflow channel from your side. Unless there is an order from me, I don't want to see this potion in this world."

"good."

Except for the ones that were used, the medicines that Shuimu sent out were basically recovered by various means. If there were any left behind, it was just a little bit, not even enough for experiments, so there was nothing to worry about.

"That's all for now. I hope you'll consider the legacy of this technique. There's no doubt that its value makes it impossible for us to give it up, but its use must be controlled. I think you also understand that you are in danger now."

Mizuki is of course the most aware of this, there are countless people who were exterminated for possessing a treasure, from the distant Uzumaki family to the recent Uchiha family. The naive Uchiha Shisui exposed the strongest illusion - Kotoamatsukami, so don't expect any ambitious people to turn a blind eye to him.

Although the most important function of the omnipotence has been discovered, for a long time there will still only be one maker, Mizuki. So it is not surprising that Tsunade chose to conceal and control it in the first place.
