Siheyuan: Timed Execution, the State Takes Action for Me

[Transported to a Siheyuan, with instant death if I fail the mission?]

When other people transmigrate, they get a new body, a System, an identity, and a job.

An Jiahao starts with none of the three: no identity, no introduction letter, and no background.

The System issues a deadly mission: visit Haizi before the deadline, or be erased!

He decides to come clean and turn himself in to the state. The rise of a great power begins with an SS reward: atomic bomb blueprints!
