Immortal Emperor Master: Eternal Undertaker

Chen Changsheng is bound to a mediocre immortality system, and he can gain lifespan and attributes as long as he sleeps. He was most afraid of trouble in his life, didn't like cultivating immortals, and didn't like fighting, so he opened a coffin shop in the world of mortals and devoted himself to studying white things. Beauty ages quickly and times change. No matter how magnificent you are, no matter how powerful you are, you will ultimately be unable to withstand the erosion of time. Over the past two hundred years, the great masters have changed one after another, but Chen Changsheng has remained firmly behind the stage, silently fulfilling his promise - "Everyone, go well, I will personally send you to your grave for peace." He who survived until the end has unknowingly become the ultimate taboo that all the worlds are least willing to mention!
