"You really do know a lot. Did Black Zetsu reveal all this to you?" Kaguya narrowed her eyes slightly, secretly making her own guess.
Shin waited quietly, neither anxious nor urging her on. After some thought, Kaguya said, "The method you just mentioned is a contingency I prepared beforehand, and it is also relatively easy to carry out. Compared to directly breaking this powerful seal, using my nature as the origin of chakra to escape would be far more convenient. Of course, if I escaped that way, I would be using the Ten-Tails' Jinchuriki as a substitute for my descent, so my strength would be somewhat diminished. But it would still be enough for the current world. Besides that, there is naturally a second method—the simplest one. Break the seal I am currently trapped in head-on. But that is difficult, extremely difficult. Hagoromo and Hamura put immense effort into this seal and anticipated every possible method I might use to escape. It can even withstand the full force of my power. Even if you and I joined forces, we could not break it. Unless..."
"Hmm?" Shin nodded slightly, signaling for her to continue.
"Unless you gather the Ten-Tails once more and summon the Divine Tree. Then, after locating this space, you would have to assemble enough overwhelming power to crush this seal head-on. Only then would it be possible for me to escape completely. Otherwise, we can only keep waiting—until the seal's power gradually weakens to the point where I can shake it. Only then will there be a chance to escape."
"Oh." Shin raised a brow and murmured, "So brute force is the only option."
"To a certain extent, that is correct," Kaguya replied.
Shin nodded and smiled confidently. "I understand. Let us end this conversation here for now.
