Delivering food to 404 late at night, there is no living person behind the door, only the rules of death.
Delivery boy Chen Mo accidentally awakens to the "rule deconstruction system" - whoever breaks the rules will die. If he breaks the rules, he can seize them.
He thought he was invincible until he was imprisoned in a strange mental hospital.
Vice-dean Zhao Deliang, a "good old man" who couldn't understand human speech, used an electric shock device to wake him up every day: "You can only remember when it hurts, I am doing it for your own good."
Chen Mo was tortured so much that he wanted to kill someone, but every time he fought back, Zhao Deliang was moved to tears: "You finally lost your temper! The treatment effect is remarkable!"
... I can't bear it anymore~
