The Substitute Experimental Subject: The Chief Is Tamed in Reverse
Tower FJ4 is one of the highest authorities overseeing Sentinels and Guides. Chen Yiheng is the chief Guide at the Tower. His younger brother, Chen Junming, a Guide, died of illness, leaving behind a dangerous experimental subject, Ming Junchen (Alpha), modeled on himself and carrying only memories of his older brother. Defying everyone's objections, Chen Yiheng resolves to personally tame this remnant of his brother, who is regarded as a failure.
