In a courtyard near the Sacred Tree.
After receiving Houka's approval, Yakushi Kabuto suspended his experiments on the three Mangekyō Sharingan and began cloning them. This time, he planned to clone ten sets first—thirty Mangekyō Sharingan in total. Three would be preserved, while the rest would be used for experiments.

The second genjutsu directly turned whatever happened within an illusion into reality. It was
