After the Death of the Real Daughter, the Target of the Attack Went Crazy with Regrets

The system said that if I conquer him, I can stay in this world forever and extend my life. But as soon as the fake daughter appeared, I failed completely. For her sake, she humiliated me, scolded me, punished me, and cursed me to death. Failure was imminent, and the system adjusted its direction in time: "Host, as long as your current body dies under the torture of the male protagonist, I can help you resurrect your body in the original world and send you back!" So, I tried my best to get everyone to kill me. As they wished, I died. But why did he go crazy after witnessing my body turn into a pool of blood?
