Taoist Remembrance Person

The story of a Taoist man who is searching for his memory alone. He has no relatives, no friends, no family, and no one knows how many years he has lived. He knows that he has lost his memory but does not know what important things he has lost. However, he has powerful magic and is so terrifying that gods and demons are not as good as humans. Let's see how this young man searches for his own life (the author is as kind as the protagonist and has no harem). Thank you for your support.
