Harry Potter: the Savior of the Devil.

Lippert fanfic, the plot of the original work has been slightly changed, but the characters remain unchanged. The protagonist is a time traveler and is invincible. In the later stage, there is occasionally a trace of romance, and neither the protagonist nor the supporting characters have a harem. The content is cool, funny, there are knives, but not much Then I hope everyone likes it. The author is busy with work, so I will occasionally postpone updates. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
