Overturning the Country: Two Emperors

One second, we were mortal enemies. He, the hero of the Northern Territory, is the god of murder in troubled times; I, the mastermind of the Southern Dynasty, am trying to kill all the people. The next second, both of them were reborn and became the worst trash in the hostile camp. He is the mad dog prince who was abandoned like a pair of worn-out shoes, and I am the sick and weak proton whose life hangs by a thread. When we met again, at the palace banquet, he put the blade at my throat, with murderous intent: "I can kill you right now." I coughed up blood and chuckled: "You will die in the hunting ground in three days. If we cooperate, both you and I can survive." From then on, beside the Mad Dog Prince, there was a sick beauty who knew everything he could. I play chess for him, clean up the court, and control the world; He holds the sword for me, wipes out the world, and treats all living beings as dust. Everyone said that the Seventh Prince raised a powerful venomous snake, but he broke his sword in public and swore: "This person will be protected by me!" No one knows that the seemingly weak proton is the real hand holding the chess piece. When the country was destroyed and a new dynasty was about to be established, he split the jade seal into two under the spotlight. "In my previous life, I lost the world and won you." "In this life, I will give you half of my kingdom."
