Siheyuan: I Transmigrated as Jia Dongxu, and Reporting Crimes Comes with Rewards

Jia Xu unexpectedly transmigrates as Jia Dongxu in Love in the Courtyard. The System bound to him tells him that if he finds a transmigrator and successfully reports them, he will receive generous rewards in his original world and be able to return there.

What he doesn't know is that there are no other transmigrators at all, and that the main characters in the courtyard can hear his every thought loud and clear.
