Shen Yu traveled through sixty years and was already an eighty-year-old man. Now he has children and grandchildren and a happy life. All that's left is to count the days until death and end this journey of life. Unexpectedly, the system came suddenly. And it's still a villain system! Shen Yu was stunned immediately! "I'm an 80-year-old man, and I'm half buried in the earth." "I've prepared the coffin." "Now let me be the villain?" "What's going on?" Shen Yu wanted to refuse. However, the system reminded that if he refused, all his descendants would be erased from the system. Including himself. In the end, Shen Yu could only compromise. For the sake of the descendants of his old Shen family, Shen Yu became a villain at the age of eighty! The first task of the system is to let him intercept the opportunity that belongs to the protagonist. Have sex with the great religious saint and detoxify her. Afterwards.... Shen Yu: It seems like I was defiled by that saint, right? Protagonist: Old thing! Take away my opportunity and sleep with my woman, and I will kill you!
