'If it's not the eldest, then I'll check on the second son.'
Chai Qihong's second son was named Chai Yi. He had been rebellious and aggressive since childhood. As a young man, he trained at a martial arts academy for three years, reaching the First Layer of the Power Realm.
When he was twenty-two, he got into a street argument and ended up crippling a man. Chai Qihong had to pay a huge sum in compensation, and Chai Yi was sent to prison for three years.
