The Necromancer in Harry Potter

After transmigrating into the world of Harry Potter, Raymond isn't worried at all. A transmigrator with a golden finger has nothing to fear.

Only after Raymond clears the Harry Potter game does he discover an even vaster future waiting to be explored.

Ravenclaw, somewhat dark, no joining the group, infinite flow.

A new author and a new story. The only thing I can guarantee is that I won't abandon it.
