I Work as an Undercover Agent in the System World

Wanxi: "Others who travel through time are at least a character, but I'm not even a character?!" Due to the increasing number of time-travelers in recent years, many time-travelers have maliciously modified the original plot, causing many small worlds to collapse, and even the administrators cannot control the situation. So an undercover agent appeared, in order to get rid of all the undercover agents who traveled through time. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
