After Rebirth, I Fell in Love with My Master

After rebirth, I wanted revenge and my friend and I had a common enemy. He saw that I was of low moral character, so he taught me how to practice. Over time, I especially trusted him. He was his apprentice in my previous life. Of course I wanted him to die. He just wanted him to become a useless person. But who can tell me that this friend of mine is my master? Why did I later become Taoist companions with Master He? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
