I Am the Destroyer of Parallel Worlds

The protagonist is the wearer, and his soul begins to travel into the body of a little beggar. He was originally very cowardly, but was pushed to the bottom by the cruelty of the world, and his awakening system changed towards the character of a madman. The whole article is awakening→change→destruction. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
