Substitute Experimental Subject: Chief, he was reversely domesticated
FJ4 Tower is one of the highest institutions managing sentinels and guides. Chen Yiheng is the chief guide in the tower. His younger brother, guide Chen Junming, died of illness, leaving behind a dangerous experimental subject (Alpha) based on himself and carrying only the memory of his brother - Ming Junchen. Regardless of everyone's opposition, Chen Yiheng decided to personally tame this relic of his younger brother who was regarded as a failure.
