Master Nourishes My Life, I Will Send Master to His Death

I treat my master like a father, but he wants to take away my life My master has told me since I was a child that I was born with yin and yang eyes and can see things that ordinary people cannot. He taught me Feng Shui and took me all over the country to look after people's houses and tombs. I thought he was my only relative in this world until I passed by his room when I got up that night. Under the dim oil lamp, he was burning a paper figure with my birth date in front of him, with my hair stuck to the back of the paper figure. The ancient book spread out next to it reads: "The way to seize a body and prolong life is to nourish it for twenty years and take it when the yang energy is at its peak." It turns out that he bought me from a trafficker eighteen years ago just to prepare a young body for himself.
