But Xing Tian wasn't a compassionate father, he didn't genuinely love this son of his. In fact, he was a man who looked out solely for his own interests. He raised his son, paid for his schooling, all because he wanted his son to help him live a life of wealth and luxury!
If faced with the choice of sacrificing either himself or his son, he wouldn't hesitate to offer up his son.
So such threats might be effective against that woman, but they were useless against him.
However, like father like son, neither was much better than the other!
