The technique that Mizuki mentioned to condense the incarnation of obsession is obviously Orochimaru's Yamata no Jutsu. In Mizuki's opinion, this technique is quite powerful, but it was not dominant under the attack of Uchiha Itachi's Susanoo, and was finally sealed by a sacred artifact, which shows that it is not powerful enough to be lawless.

The biggest advantage of this technique that Mizuki saw was its ability to condense souls and mental power. The damage that the Corpse Reincarnation had on Orochimaru's spirit was fully demonstrated in his defeat to Uchiha Itachi. However, without the Eight-Headed Technique, Orochimaru's soul might have long been drowned in the damage caused by his repeated transformations. Even when he was counterattacked by Uchiha Sasuke in the end, he had a chance to turn the tables. If it weren't for the powerful sealing ability of the Sacred Sword of Tentsuka, it would have been almost impossible to kill Orochimaru.

Mizuki certainly doesn't want to turn into the Yamata-no-Orochi. As an ancient mythical beast known as the "divine dragon", it obviously has unique symbolic significance. Mizuki also doesn't want to steal the spotlight from Orochimaru. The key is that this technique, which brings tremendous protection to the mind and soul, is like a timely help to Mizuki, whose spirit is being eroded by natural energy. Any reference to it will bring great help to Mizuki.

Mizuki made a request, but he would never act so hungry in front of Kabuto Yakushi. He just wanted to force Kabuto Yakushi to make an appropriate choice. The Eight-Headed Technique is Mizuki's ultimate goal. Of course, the Curse Sealing Technique and the Living Corpse Reincarnation Technique are barely enough. As for the Impure World Reincarnation, it can only be regarded as a supplement. As for other techniques, it would be better to have them, but he would not force it if he doesn't have them.

Facing Mizuki's request, Yakushi Kabuto said helplessly: "I seem to understand. Although your greed makes me very embarrassed, it seems that you are not aimless. However, I have not seen Lord Orochimaru's information in this regard. According to what you said, it is obvious that this is the last life-saving skill. If nothing unexpected happens, I will not be able to get this skill at all."

"That's a pity." Shuimu shrugged nonchalantly. "I don't have the information in this regard. What you offer doesn't satisfy me completely. So, I'm sorry, the deal is not concluded. Either you complete what we agreed on and leave, or you change your request."

There is actually not much comparison between what Mizuki and Kabuto Yakushi took out. Impure World Reincarnation and Undead Reincarnation are obviously related to combat and life extension, while the main function of the Breathing Technique is similar to the infinite supply of auxiliary. It is difficult to say which one is better or worse, it depends on the specific needs. The application range of the Breathing Technique is wider, and it can make up for many defects in talent, which is something that Undead Reincarnation and Impure World Reincarnation cannot do. Although it does not provide direct combat power, just look at the earth-shaking changes that the Sage Mode has brought to Mizuki.

Mizuki's refusal made Kabuto Yakushi give up, but there was nothing he could do. Without the right bargaining chips, no one would hand over their cards. Just like the three-magatama Sharingan in his hand, in terms of value, it was not as good as Mizuki's Breath-Retaining Technique, but Kabuto Yakushi would never exchange it. The infinite possibilities of the Sharingan made it difficult for anyone to put it on the negotiating table easily.

"Forget it then. Don't use the Breath Containment Technique. Try something else." Kabuto Yakushi said with regret. In his current situation, it was obviously impossible to dig out Orochimaru's trump card. How could he study it on his own? Not to mention whether it would work or not, he simply didn't have the time. The Sharingan in his hand was enough for him to study for a long time.

"Oh? What other techniques do you fancy?"

Shuimu can clearly distinguish which techniques are valuable. Things that can be exchanged with Impure World Reincarnation and Non-Corpse Reincarnation must not be simple. Yakushi Kabuto is not stupid and will not agree to a deal that is too disadvantageous.

"I want the training method of Sage Mode!"

Yakushi Kabuto said in a decisive tone.

"Sage Mode?" Shuimu's heart was shocked, and he looked at Yakushi Kabuto in disbelief, "I will reply to what you said before. Without the Breath Containment Technique, your chakra level is not enough to qualify you to learn the Sage Mode. And I remind you that the Sage Mode I use may not be suitable for you."

Putting aside the amount of chakra, it is very difficult to find a medium for the first contact with natural energy. Jiraiya and Uzumaki Naruto learned the frog fairy technique, and they succeeded with the help of Fukasaku Sage from time to time. Mizuki also took a shortcut that suited him and used the chakra of the tailed beast. What can Kabuto Yakushi use? Use Orochimaru's cells again? Orochimaru is not dead yet, and Kabuto Yakushi does not have the courage to do such a thing under his nose.

"I know that. I'll take care of everything. Are you satisfied with the deal?"

"The soul gathering formation should be cancelled, and the Sage Mode should be replaced with Impure World Reincarnation and Undead Reincarnation."

Anyway, in the end, Kabuto Yakushi will most likely pay attention to the snake fairy technique. For a civilian ninja with no foundation and bloodline limit, it is best to go the Sage Mode if possible. The improvement in strength will be obvious.

Shuimu's foundation lies in the Breath Concealment Technique, and the Sage Mode is just one of the means. In exchange for two useful forbidden techniques, it is also very cost-effective.

Kabuto Yakushi agreed to Mizuki's bargaining after hesitating for a while. The beginning of this incident was for the Sharingan. The huge consumption of using the Sharingan by non-Uchiha forced Kabuto Yakushi to focus on Mizuki's Breath Containment Technique, but it seems that he can't get the Breath Containment Technique, so changing the way and using Senjutsu Chakra to promote it is also a good method. Kabuto Yakushi, who knows the connection between the seal and the Senjutsu, has witnessed with his own eyes the strengthening of Uchiha Sasuke's Sharingan by the seal, and also understands the great help of high-level energy to the Sharingan. It is not surprising that the Sage Mode is an alternative.

"Okay, but if I find that your Sage Mode has problems, how should I ask you?"

"I am the leader of the eighth genin team. I have many opportunities to leave the village. Don't say you can't find me. Of course..." Mizuki said with a relaxed smile, "If our transaction is discovered, don't blame me for turning hostile."

"Of course." Pharmacist Kabuto nodded.

"Very good, the deal is done." Shuimu was quite satisfied with the gains. "Finally, we need to agree on a transaction method that relies on mutual trust..."

Shuimu took out a blank scroll and spread it out: "Write down the Curse Seal Technique and Yin Healing and Destruction Technique. Once I confirm that they are correct, you can leave. When you are safe, I will give you the Spiritual Rashomon and Water Transformation Technique. Then we will start the Sage Mode transaction..."

With the seal technique, it would be worthwhile for Mizuki to use the Sage Mode. A few powerful ninjutsu would also ensure that Kabuto Yakushi could leave safely.
