Inherited Po Tao Temple and Gave Me a System?!

My name is Lin Xuan, and my Taoist name is Sanxuan. I live in a remote Taoist temple in a small mountain village. That rainy night, the master took his brothers out to do errands and never came back. From then on, I was the only one left in the Taoist temple. One day, on the same rainy night as that day, I was lying on the bed, and there was a knock on the door. Just as I was about to open the door, a mysterious voice came, "Don't go, junior." This novel and its characters are purely fictitious.
