After Death, Possession Is Guaranteed to Succeed

It talks too much and is a bit toxic, but the plot is okay. I'm not crazy enough about what I do, and I haven't fully used my golden fingers yet. You don't have to worry about the person who seizes the body and the training and the plot. You can waste it as soon as the cooldown time is up. There is no need for the heroine. If the password to seize the body is known, it is best as little as possible, even if it is guessed, it will not work. The smart ones will figure out your cooldown time sooner or later, the soul attack ones will be hit sooner or later. It depends on how you play later.

The subject matter is novel, but the layout is too small.
