Though he threatened these people, he was actually very worried. What if they did not take his bait and attacked him? No one wanted to die without a reason. And that too for such a silly one.
Zhou Zeming liked his wife and thus wanted to clean him up. Maybe in the eyes of that mer, his wife was worth murdering someone. But Yu Fei who had met with constant betrayals from his wife did not think so.
He had saved enough resources and just wanted to return home, as long as he could leave peacefully who cared if he had a wife or not? His parents and sisters would certainly not look down on him if he was to return.
Only those who were worried that they would not get or meet with someone better than Xiao Chuxia would do something like this, but Yu Fei had no such qualms. Someone who could break her promises to him can also abandon Zhou Zeming, what's the point of chasing after such a woman?
He might as well divorce her and leave this place!
