Lan Yu was hit and killed by a runaway truck just after he arrived in City A. Is this a distortion of human nature or a loss of morals? Please see...
After being hit, he accidentally traveled through time, and was forced to do a task by the damn system. If he didn't complete the task, he would die. Although he could be resurrected, he could still feel the pain of death. After Lan Yu experienced it, he no longer dared to disobey the system's orders.
If you want to return to modern times, you must defeat the male protagonist. You cannot let him hate you, otherwise the price will still be death. However, the system is still very user-friendly. You can gain experience by completing certain tasks, and these experiences can be exchanged for death-free gold medals...
