Under the pale light, Orochimaru and Hanzo stared intently at the potion in front of them, waiting for its synthesis reaction to reach stability.

Since Orochimaru came here, during this time, Hanzo and Orochimaru have completely forgotten to sleep and eat, and they are studying and testing every day, except for resting and burying their heads in work.

Originally, Orochimaru was also going to return to Konoha from time to time to show up, so as not to disappear for a long time and arouse the curiosity of others. However, when the negotiations between the five major powers entered the final stage, there were only some differences in details, and Orochimaru ignored the affairs of the village, squatting in the base and concentrating on exploring the secrets of the spell seal with Hanzo, after all, at this time, Konoha no longer needed a powerful ninja like Orochimaru to stand up and show his presence and put pressure on other countries.

Later, when Orochimaru studied Shigego's abilities, he suddenly discovered that the source of his strength was an enzyme in his body, and this enzyme turned out to be the same as the enzyme he discovered when he studied immortal arts before.

This is also the reason why he asked Hanzo to continue his previous research project on immortal arts with him.

Because of this, Orochimaru changed the direction of his research on Shigego, from the exploration of the mystery of Shigego's ability to the study of the origin of Shigego's ability.

Then Orochimaru went out to collect relevant information, from whether Shigego had eaten anything special when he was a child, whether he had encountered anything special, to the places where Shigego had been, to the history of the Libra clan to which Shigego belonged and the bones of his predecessors, all of them, as long as it was possible, Orochimaru did not let go of collecting.

This is also the only time Orochimaru leaves the base and goes out. Of course, Hanzo didn't care how Orochimaru got this information outside, and no matter how he screened it, it was useless to Hanzo. He only cares about whether he can participate in the follow-up development.

Seeing that the medicine in the test tube stabilized, Hanzo was like a dream, and said to himself excitedly: "This ...... Was this a success? ”

Orochimaru didn't have any special expression, but the flickering gaze still showed that his heart was not as calm as he appeared, but as excited as Hanzo, "Don't you know if you succeed in giving it a try!" Then he stepped forward step by step under Hanzo's gaze, and carefully took out a little reagent to do the relevant testing.

After waiting for a while, Hanzo looked at Orochimaru with a relieved smile, and understood that they had really succeeded this time.

Looking at the tube of potion, Hanzo's breathing became heavy. It is also impossible to be half hidden and not excited, the most direct benefit of having a spell mark is the improvement of strength, and it may even enter the ranks of the upper ninja faster.

Of course, this is not to say that the power of the curse mark can make people rise to a higher level and have the strength of the upper ninja, but because the process of receiving the curse mark is a tempering of a person's will.

However, Hanzo himself never seemed to think about whether he could or not, and he completely forgot that the spell mark was also a matter of facing the risk of death.

"Hey~ That's not right! The spell mark shouldn't be like this, it's a spell, not a potion. Could it be ......" Hanzo suddenly thought of this, and couldn't help but feel uneasy in his heart, for fear that his addition would cause a change in the spell seal, so he asked: "Lord Orochimaru, although it can be stable and easy to store in its current state, the problem of how to use it has not been solved!" You can't drink it when you're fighting. ”

Seeing that Orochimaru did not refute and was unhappy, Hanzo continued to express his doubts: "And our medicine acts directly on the body, although the maddening factor is weakened a lot, but if you take it directly, you may lose your mind......"

Standing up, Orochimaru looked at Hanzo with his hands spread out, and said, "Hanzo, have you forgotten the method we mentioned in the Dragon Cave before?" ”

Hanzo frowned, not even though he had some guesses, but he was not sure, "Sealing technique? ”。

"That's right! Sealing. ”

"That's still a bit far from success, and that's plus the time for animal experiments." Hanzo was relieved that he hadn't changed anything, and he was disappointed that the spell had not yet come out.

And I don't know much about sealing, and I only took the opportunity to learn some shallow knowledge before, which is far from practical use, not to mention the advanced things used by Orochimaru.

"Hanzo, don't underestimate me, I'm one of the three ninjas, my energy is not comparable to you, when you rest, I will also use part of the time to do some supporting things."

Hearing Orochimaru say this, Hanzo couldn't help but curse in his heart, "I slot", I couldn't guess whether Orochimaru was deliberately concealing it or going with the flow, and hid his emotional temptation: "That is to say, ......"

"That's right!" Then Orochimaru put the reagent in his mouth and swallowed it, while saying vaguely, "I've already done the rest, so I'm left with the live experiment." ”

"Ahh That's it! Hanzo duly expressed his surprise.

"One more thing you're wrong." Looking at Hanzo's puzzled look, Orochimaru explained, "There is no need to do any animal experiments, why don't you use so many prisoners here with materials." ”

Hearing Orochimaru say this, Hanzo was stunned, and his face was immediately bad, although he knew that there would be this day, but when Orochimaru was really ready to start doing such a thing, Hanzo was still very uncomfortable in his heart, and there was a mental obstacle.

"Hanzo, I heard from God that you oppose his human experiments, and I hope you don't do that here, understand?"

"Yes!" Hanzo broke free from his emotions and immediately said, knowing that this was one of the few warnings that Orochimaru had given him.

Staring at Hanzo for a while, to make sure Hanzou wouldn't make such a mistake, Orochimaru turned around and walked out of the laboratory in the direction of the prisoner, "Hanzo, you go and ask Junmaru to come and find me in the prison cell, and then you can go and rest." ”

"Yes!" Hanzo responded.

Seeing Orochimaru disappear in front of his eyes, Hanzo also walked out of the laboratory to find Kimimaro.

Standing in the corner and observing secretly, Hanzo found that Junmaro entered and came out shortly after, and left the base after seeing Shigego, not knowing where to go.

I can come up with some when I go to Shigego Hanzo, but I can't guess what I'm going out for.

Hanzo then went to Shigego to probe the tone, "Hey, Shigego, I've been busy with work, I haven't seen you for a long time, how is it lately, is the situation out of control getting better?" ”

Jugo squatted in the corner and raised his head when he heard the voice, "It turned out to be Hanzo, I haven't seen you for a long time, my problem is still like that, but with Jun Mario, I can calm down quickly." Seeing that it was Hanzo, Shigego said with a smile.

After chatting casually for a while, Hanzo asked the question he wanted to ask the most: "Where did Jun Maro go?" Then I got my own answer. To make it less obvious, Hanzo talked to Shigego again, and then took his leave and left.

"It turns out that I went to the country of Tian to meet the daimyo, is the sound ninja village going to be established?" Hanzo guessed, and then it occurred to him that maybe it wasn't necessarily to build a village, maybe it was to pave the way for the future and exchange some test subjects.

When I went back to the bedroom, I thought about something, and Hanzo immersed himself in studying......
