Master and Disciple [Quick Transmigration]

Nobody in this world has taught the villains what good and evil, right and wrong mean. So I came. I have no right to choose your future for you, but I will give everything I have to give you the right to choose. * Current progress: Revised version as of 2019.7.31. [Worlds 1, 2, and 3 will no longer be changed; the related logic is complete.
