Before I went to work as an undercover agent, the old man handed me a book. I looked down and saw five big characters shining brightly in front of my eyes - "Laws of Undercover Agents", which suddenly seemed to weigh a thousand pounds in my hand.

After that, my life changed from being a person with my tail between my legs to being a person with two tails between my legs.
