"Okay." Yakushi Kabuto agreed. Other things could be put aside for the time being. The most important thing now was to get out of this situation. "However, I can't write at all in my current condition..."

Mizuki looked at the bandaged Pharmacist Kabuto and understood his situation. It was already difficult for him to move his head and speak, and now asking him to write with his hands was simply an impossible task.

"Okay, you tell me, and I'll write it."

The seriously injured Kabuto Yakushi was unable to put up much resistance in this situation. Moreover, Mizuki was also familiar with the curse seal. Kabuto Yakushi knew that he could not do anything with this technique, so he had to hand it over to Mizuki honestly.

After a long time, Mizuki looked at the scroll in his hand, frowning and thinking for a long time. Then he looked up at the expectant Kabuto Yakushi and asked, "There is no problem with the medical ninjutsu - Yin Healing and Destruction, but I am very confused about the curse seal technique. There is no way to remove this ninjutsu. Why is that?"

The basic framework of the curse-sealing technique shown in the scroll in his hand is very clear, and there is no conflict with Mizuki's own research results and speculations. In the general direction, Mizuki believes that Kabuto Yakushi has not tampered with it. As for the details, it will not be too late to look into them slowly after returning.

The key is that there is a situation that is obviously beyond common sense. According to Shuimu's understanding, all ninjutsu based on sealing techniques should be reversible. If they can be sealed, they can be unsealed, just like the five elements seal, there is a corresponding five elements seal - unsealing. The fourth generation Hokage Minato Namikaze left behind the Eight Diagrams Seal to seal the Nine-Tails, which is also the key to unseal. Even the Shiki Fuujin was broken by Orochimaru and his sealed hands were retrieved. The strange thing about the seal technique is that there is no room for unsealing. Once you are cursed, you can only go one way to the end, unless you completely remove the mark of the seal owner who is entangled with the spirit of the recipient. But how can this be done? Unless there is a divine artifact like the Ten-fisted Sword with the coercive power of the world rules to seal. Theoretically speaking, once the seal is in effect, it cannot be eliminated. Unless you resist the invasion of the seal from the beginning like White Zetsu, otherwise, it will be difficult to limit it by conventional means, let alone unseal it.

"I was too arrogant to think that I could crack the secret technique that Orochimaru has been studying for half his life in just two or three years. It seems that I can only imitate it after understanding the principle."

Hearing Mizuki's question, Kabuto Yakushi, whose life was closely related to it, did not dare to neglect it. After thinking carefully, he replied, "I don't know about this question either. The difficulty of the seal technique is too great. In fact, even after I got it, I was only very skilled in the surface application. But the core problem obviously requires extremely profound attainments in the seal technique to figure out. As for the principle, I once heard Lord Orochimaru say: There is nothing a ninja cannot do."

"Is there anything I can't do?" Mizuki couldn't help but mutter to himself. Logically, this statement must be problematic. Ninjas are not omnipotent and always have their limits. However, Orochimaru's conceited words reflected a problem from one side, that is, as far as imagination goes, ninjas can basically do everything, which even includes reversing life and death.

"That means this technique can be broken, but I just can't understand it?"

"That's right." Yakushi Kabuto answered affirmatively.

"Are you sure this is all there is to the curse technique?" Shuimu asked suspiciously.

"I can't be sure, but this is all I know. Lord Orochimaru is not someone I can easily guess about."

"There is too little information. Do I have to do the experiment myself?"

After thinking about it, Mizuki gave up the idea. Orochimaru had sacrificed countless experimental subjects in order to obtain the perfect Heaven's Curse Seal, and it was almost impossible for Mizuki to do it again.

"There is another part to the deal. I want the experimental data on the curse seal that you collected, especially the detailed information on the Sound Five."

“This information is very valuable and difficult to deliver.”

"Orochimaru has many abandoned laboratories. Just find one and put your qualifications in it, then notify me to pick it up."

Pharmacist Kabuto hesitated and said, "Of course you can, but I will be at a disadvantage if I do that."

"If you practice Sage Mode, I'll give you a chance to ask questions!"

"A chance to ask a question? That's too cheap. Are you going to cancel the deal if I don't agree to your request?"

"Yes." He still had a mutated, half-finished curse mark on his body. If he didn't figure this out thoroughly, who knew when something would go wrong?

"I can give you a hint. Sage Mode is different from ordinary ninjutsu. The dangers and difficulties involved cannot be overcome with intelligence and hard work. You can't possibly ask Orochimaru for advice on such a private matter, right? You'd better think carefully about the value of a question..."

Shui Mu's firm words made Yao Shi Dou hesitate a little. After thinking about Shui Mu's warning, he finally nodded and agreed: "Then it's settled. Now that things have come to this, you can't go back on your word again."

"No more accidents will happen."

…

Having obtained a satisfactory harvest, one can look forward to greater benefits, and Pharmacist Kabuto is obviously more anxious than oneself?

"More anxious? No?" Shuimu suddenly stopped running on the way back to the village, looked back in the direction of Pharmacist Kabuto, it was too late to chase back now!

"It seems that I made a mistake. I was blinded by the forbidden techniques. I thought I had won, but I didn't expect that Yakushi Kabuto didn't suffer any loss either!"

Mizuki just now suddenly realized that the impatient Kabuto Yakushi was not only trying to get away as quickly as possible, his fundamental purpose was to obtain the Sage Mode!

Kabuto Yakushi's first goal is the Breath Concealing Technique, and his second goal is the Sage Mode. Because of the change in Kabuto Yakushi's goal, Mizuki overlooked that the two techniques have a common feature - providing unparalleled chakra, one is quantitative change, and the other is qualitative change.

Mizuki originally thought that Kabuto Yakushi wanted the Sage Mode in order to improve his combat power, but now it seems that it is not that simple at all. Whether it is the Breathing Technique or the Sage Mode, they are just stepping stones to achieve another goal.

A large amount of chakra or high-level energy such as Senjutsu Chakra provided by the Breath Containment Technique is needed to proceed to the next step. In Shuimu's impression, there are only a few people who have this need.

"Most likely it's the three major eye techniques! The Samsara Eye is obviously impossible, and the Byakugan is unlikely. The only possibility is the most popular Sharingan. Use a large amount or high-quality chakra to forcibly activate and upgrade it?"
