The Forgotten Slayer - Chapter 3: Dark

He is the heir of Di Hao Group; decisive, cold-blooded yet dotes on his wife a little too much.

Off the charts.]Doctor? Check. Pilot? Check. Eunuch? …Regrettably, check. Every script forces him to relive past missions, and somehow, he’s nailing every performance.
