The modern librarian {Lin Yan}, who complained about the ceiling of the world, was hunted down by the interstellar criminal organization Black Star Alliance. He traveled through the ancient palace with the selection system and became the unpopular seventh prince. System: Choose one of three options: lie down, act cool, or indulge in green tea! Facing the difficulties caused by his selfish colleagues after time travel, the assassination of his betrayed friends, and the pursuit by interstellar organizations across time and space, Lin Yan relied on the complaining + selection system to gain the favor of the emperor, the favor of the courtiers, and the loyalty of the bodyguards. The seemingly kind-hearted Su Qingyuan always "happens" to save the situation, but in fact he is calculating every step, and Lin Yan can see through it at a glance. When the system gave him the options of "erasing her memory of calculations" or "turning the tables", he sneered: "Green tea? Watch me tame her with my complaints!" From then on, there was a vicious-tongued prince in the palace.
