Three Sentences to Make the Overpowered Hero Break Down

Meng Xuli, the young master of the top immortal sect in the Nine Provinces, was peerlessly handsome, refined and gifted beyond compare. He was the most promising prodigy to ascend to immortality, yet he married early, and married a man at that. Countless people lamented the waste. Some said Ying Huai had no cultivation, was weak and easy to bully, and was useless in every way, completely unworthy of Meng Xuli. Others said Meng Xuli married him only because he had a rare, naturally born agarwood bone, and would cast him aside once he had served his purpose. Still others said Meng Xuli let his clan members bully Ying Huai and was always cold toward him, proving he did not care about him at all. Ying Huai did not care. He continued to love Meng Xuli with all his heart, and looked forward to the day Meng Xuli would love him back. Later, people said Meng Xuli was deeply in love with his master, and that he cultivated so desperately just to ascend to the Upper Realm and find him. They said Ying Huai looked very much like Meng Xuli's master. He was nothing but a substitute. Ying Huai finally understood. So that was it. * Meng Xuli was cold and indifferent by nature. His heart belonged only to the path of cultivation and ascension. Everyone and everything else was insignificant to him, not worth a second thought. So whenever Ying Huai gazed at him with shining eyes and asked if he loved him, Meng Xuli could only think how vulgar mortals were. Later, Ying Huai fell off a cliff and died. Before that, he left behind three final words. "Honestly, you're really bad in bed." "I always treated you as a substitute for the person I love. You look more like him when you smile, but it's a pity you don't smile much." "I'm pregnant, but the child isn't yours." On the first day, Meng Xuli was unmoved. On the second day, Meng Xuli's hair turned white overnight, his eyes bloodshot, and he fell completely into demonic cultivation. On the third day, Meng Xuli went on a killing spree, staining the entire cultivation world with blood. * A hundred years later, on the wedding day of Demon Lord Ying Huai and Taiyan Divine Lord, the newly crowned Demon Emperor charged up the mountain from its foot, eyes red with rage, slaughtering everyone in his path. The System shrieked in his mind: Host, isn't this the target you got wrong last time?! Meng Xuli's silver hair whipped in the wind. Covered in blood and radiating murderous rage, he stared fixedly at Ying Huai and advanced toward him, one step at a time. Ying Huai swallowed, then shoved Taiyan Divine Lord forward. "Go on, husband!" Meng Xuli's gaze fell on the Divine Lord, dressed in red wedding robes and looking seven or eight tenths like him, and he went even more completely mad. Theme: It is never too late to mend your ways, and doing so is a great virtue.
