Siheyuan: Orphaned Child of an Underground Agent, Transferred to a Factory

I was watching short videos when the light turned green. Then I opened my eyes to a yellowed ceiling. My birth parents were underground operatives who had both died in the line of duty, and I'd grown up adopted by a commanding officer. After a serious injury forced me to retire from the military, I was appointed head of security at the Red Star Steelworks. Bracing myself against the bed, I sat up and felt out my new body's strength. I'd have to learn the rules of this factory from scratch.
