Time travel? Sick rice? Soon? Garbage system? What is all this mess? Zhang Qingyin: You can travel through time even after a good sleep. Can you be more careless? It's just time travel. Why aren't there the hordes of beautiful men mentioned in the novel? There is only one insidious little guard and a garbage system that wants to make me burp at every turn... Yi An: I accidentally fell in front of the little girl's door. I didn't expect the little girl to be so enthusiastic. To pity him, she even asked him, a dignified prince, to be her personal guard. He really thanked her and the whole family. Small Theater: At the beginning, Zhang Qingyin: Yi An, come here and warm my bed. Yi An: This is not my duty. Later, Zhang Qingyin: Get off my bed. Yi An: I am fulfilling my duty. This is a story in which the heroine thinks she is a big bad wolf, but is eaten one by one by the real big bad wolf.
