Daming: I, Zhu Xiongying, Start the Game by Pretending to Be Dead

The city of Yingtian Mansion was filled with white hangings, and Zhu Yuanzhang held on to the coffin without letting go, crying until he was unconscious. I opened my eyes in the coffin, and someone called me "hero" from outside. You were doing experiments in the laboratory just now, why are you lying here? Grandpa Huang, don't cry, your grandson is not dead yet.
