Luo Jingxuan transformed into the cannon fodder prince in the Machiavellian novel, and was bound to the "black humor" system. His mission was to make all the villains laugh and be tricked to death by him. He originally wanted to survive, but he was forced to perform stand-up comedy in the court, laughing his enemies until they had a stroke, his allies until they turned against each other, and his beloved heroine until she drew her sword. When he finally ascended to the throne by stabbing everyone in the back, he discovered that the biggest betrayer was the system that had been acting with him.
