How Could I, the Emperor, Become Empress?

Emperor Xiao Zheng executed Shen Ying, his childhood friend who had fought by his side through life and death. As Shen Ying lay dying, he said in utter disappointment that after years on the throne, Xiao Zheng had grown increasingly suspicious and was no longer the sincere-hearted Xiao Mingyu he once knew. The next day, Shen Ying's loyal subordinate attempted to take revenge. After being gravely wounded, he returned sixteen years into the past. When he opened his eyes, he came face to face with the younger version of himself. Faced with his former self, Xiao Zheng naturally chose to strangle him! Xiao Mingyu: ? I'll strangle you first, you monster! Xiao Mingyu: "I owe my success today to you more than anyone else. I shall make you empress!" Xiao Zheng: ? After working hard for two lifetimes, he went from emperor to empress. My corrupted self gets topped by my younger self Xiao Mingyu (spirited young general top) x Xiao Zheng (ruthless emperor bottom) One adorable puppy and one mad wolf A selfcest romance with a younger top. They're alike only in appearance; their personalities and values are completely different. Feel free to treat them as two separate people. P.S. Xiao Zheng is the rare-character name Xiao Mingyu adopted after ascending the throne, so that ordinary people could avoid using the emperor's name. It's also to distinguish the top from the bottom. They only look alike. There's an age gap: Xiao Mingyu is youthful and pretty, while Xiao Zheng is mature and handsome. The story is about a ruthless bastard who has been through a lot and transmigrates back to the past. He thinks Heaven has given him a chance to make up with his childhood friend, only to get topped by his younger self, a beautiful, kind, pure little white flower.
