"After absorbing the ocular power of so many Sharingan, I still couldn't evolve a new Mangekyō Sharingan? What a pity!" Xiao Xie took out a mirror and looked at the three tomoe in his left eye, unable to stop himself from sighing.

The reason Orochimaru wanted to seize Sasuke Uchiha's body was because he had suffered
