Supernatural: the Last Lamplighter

Walking at night with a lantern, avoiding strangers. My name is Zhou Pingan, a lamp holder. The Mao lantern is lit once every three years. When the lantern is on, the soul returns, but when the lantern goes out, the soul dies. Grandpa pretended to be crazy for twelve years, and before he died, he gave me the lamp. The wick has three years of oil left, and three years is the day I die. People began to die in the county town, and they all died laughing. After checking, it turned out to be an old account from thirty years ago. Someone wants to save one hundred and eight lives in exchange for his daughter's life. The introduction is my first love that drowned by the river. There is only one way to continue the lamp, to light her soul into the lamp. When the light is on, I live, but she cannot be reincarnated. When the lights go out, she is reincarnated and I die. Guess, did I order it?
