Li Zheng, the puppet emperor of the Dajing Dynasty, has lived in an established "plot" since he was born. He is like a programmed NPC, and his every word and deed is bound by invisible rules. He is gentle and timid, with a delicate mind, and is used to silently taking care of the people around him. Even if the other person is just an inconspicuous little eunuch or maid in the palace, he will never act like an emperor. Until one day, he suddenly awakened to self-awareness and realized that his life was not destined, and those so-called "plot nodes" and "character settings" could be broken. Above the court, the genius inventor Su Jin appears to be assisting, but in fact he is secretly plotting and using various novel inventions to control the court situation in an attempt to subvert the imperial power and become the controller behind the scenes. After awakening, Li Zheng did not choose to fight head-on. Instead, he used his gentleness and carefulness to win over people's hearts little by little and resolve the crisis. While healing the people around him, he also slowly healed his timid and timid self. He used the softest way to fight against Su Jin's conspiracy, and on the road to the emperor, he embarked on his own, warm and powerful road of daily healing, and finally got rid of the fate of NPC and became a king who truly controls his own life.
