Explanation

Mizuki had little interest in the path Orochimaru chose. Whether it was immortality or exploring the unknown, neither held much appeal for him.

"This isn't the place to talk. Let's get out of here first!"

In the secret chamber, which had originally held only three figures, Mizuki's physical clone, Shin, suddenly appeared. He grabbed Orochimaru by the shoulder and used the Flying Raijin Jutsu. Shin and Orochimaru vanished in an instant, leaving behind only Mizuki's original body and the unconscious Anko Mitarashi. That carefree female ninja probably had some doubts about Mizuki's actions, but she could never have guessed that Mizuki's target had never been her.

Although Orochimaru's resurrection left Mizuki with important matters to handle, since Anko Mitarashi had become a tool Mizuki used, he naturally had to ensure her safety.

Orochimaru's resurrection itself had drawn out the obsession within the Heaven Curse Mark, but that did not necessarily mean the Heaven Curse Mark would disappear. Just as Itachi Uchiha sealing him with the Totsuka Blade had nothing to do with removing the curse mark, the Eight Branches Technique and the resurrection of a spiritual obsession had no causal relation to lifting it.

Yet the Heaven Curse Marks on Sasuke Uchiha and Anko Mitarashi had indeed vanished. The reason was simple: Orochimaru had actively drawn them out. Other than the creator of the curse mark, no one else had any way to deal with it. After the curse mark erupted, it squeezed its host's body to produce a large amount of curse mark chakra—a form of senjutsu chakra.
