After death, a "thought" will be left behind. Ordinary thoughts will dissipate in three days. The resentment persists for three years. But my sister Nian, ten years later, is still calling my name. My name is Lin Ye, an undertaker at Jiangcheng Funeral Home. It wasn't until that night that the Nian Dao in the morgue suddenly spoke and said one sentence to me - "Brother, I'm not dead." From that night on, I didn't know that there was a group of people in the world called "Nian Masters". They eat other people's obsessions to survive, and kill everyone who sees the truth. And I have only one goal: to wipe those who ate my sister from this world one by one.
