Sasuke took Sakura to the research room of Orochimaru and Yakushidou, which was far away from the place where the battle had just been fought and was not affected, so the surrounding objects were still well preserved, but there were some blood stains dripping in some places, and it can be guessed that this must be Yakushidou's.

It must have been Yakushidou who secretly took something from here when Sakura and Sasuke were fighting.

…

Sasuke began to help Sakura find it, because the research of Orochimaru and Yakushidou was more cruel, so he could see a lot of human organs soaked by special potions, and some evil drugs were among them, and when Sasuke rummaged through them, his brows were furrowed, so he looked extremely reluctant.

However, for Sakura's sakura, he still looked very carefully.

Sasuke is not interested in medicine and evil research, so he doesn't know much about it, but over the years with Orochimaru, he has been exposed to it and knows some of the most superficial, so he found a few and showed them to Sakura.

Sakura smiled bitterly, although she is indeed an expert in medical ninjutsu, but she is not strong enough, she can know the level of medicine at a glance, if it is refined by Tsunade, it is easy to say.

Orochimaru's research, she also doesn't know anything.

Otherwise, she would have been able to try to develop a drug to remove the curse mark on her own.

Removing Orochimaru's curse mark is currently impossible for Tsunade and Sakura.

However, Sakura can't be too idiotic in front of Sasuke. She pretended to understand and nodded to Sasuke.

Then, he put aside the suspicious medicine that Sasuke had found, and had no intention of taking it.

"Is there a manuscript of a medical book that Orochimaru has successfully researched?"

After looking for a while, Sakura felt that it was almost impossible to find the finished product directly. Thinking about it, Orochimaru and Yakushidou are not bored yet, refining some medicines in advance that can make the spell mark evolve to the second stage, and put it there, waiting for Sakura to come and get it.

It doesn't make sense.

Therefore, Sakura could only give up that method and decided to find a prescription and refine it herself. As for the suspicious medicine that Sasuke found, Sakura is not so bold, in case after eating it, not only does the spell mark not be upgraded, but the body directly turns into a monster, then it will be a big game.

Sasuke thought for a moment and said, "I remember, there seems to be a secret room here. ”

Sasuke took out the scabbard of the Kusanagi sword and stabbed it behind a medicine shelf, not to mention, it really allowed Sasuke to find the secret room, however, it was very messy inside, and it looked like it had been turned over.

Sakura and Sasuke immediately thought of Yakushi.

'Damn, he didn't take away the research on the sigils. ’

Sakura regretted a little, knowing that this medicine master had ruined her good deeds, she shouldn't have punched him just now, but stabbed him to death with a sword, so that there would be no such troublesome thing now.

There was a lot of information scattered on the ground, and Sakura began to pick it up and check it, it was very messy, basically it was conjecture and manuscripts, not as standardized as when she was learning medical ninjutsu with Tsunade Hokage.

After all, Tsunade Hokage's medical ninjutsu knowledge has been customized by herself, and she has used it to educate her disciples.

Orochimaru is different, he is a selfish researcher, so almost all the research materials are manuscripts and disorganized.

Fortunately, Sakura has an extremely deep foundation in medical ninjutsu, and she can also understand some of Orochimaru's manuscripts.

Obviously, after a little tidying up, it was discovered that Yakushidou had taken away materials related to the reincarnation of the filthy earth and the research of some cruel creatures.

Sakura wanted to get the information about the reincarnation of the dirty earth, but there was no way to do it if she was taken away by Yakushidou.

She asked Sasuke to help sort it out, and Sasuke had a headache, he couldn't read these complicated manuscripts at all.

When I was at Konoha Ninja School, Sakura's cardinal learning was the best in the class.

It's the same now, after searching for nearly half a day, Sakura finally found the manuscript information of Orochimaru's autographed manuscript that has completely increased the power of the curse mark to state two.
