I Was a Hermit in the Song Dynasty

"If you could choose a dynasty, where would you choose to go?" A post went viral on the Internet, and people rushed to repost it. "Of course it's the Song Dynasty. The salary is so high and the food is delicious." This answer in one of the comments is eye-catching. At this moment, a reply appeared upstairs: "Are you willing to return to the Song Dynasty?" Fan Yu replied "yes" without thinking, then put the phone in his pocket and watched the bustling city return to his life. No one knew what would happen to this seemingly joking remark. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
