Night Soul was aware that the deputy head had waited for today for a long time. In fact, the deputy head had tried to harm him many times before, but had never succeeded. Besides, he didn't have evidence to prove it, so he couldn't do anything about it.
In the killer organization, the deputy head had no less influence than him, so he didn't dare to turn against the deputy head. There would be no winner, and someone else would take advantage of their conflict. He would also lose his position as the head of the killer organization. Therefore, he chose to tolerate it and sat in his position steadily.
Behind the other members' back, Night Soul had tried to murder the deputy head too, so he wasn't too mad when the deputy head did the same thing to him.
Both of them wanted the other dead, but they knew what they shouldn't do. No matter how serious the conflicts between them became, they wouldn't hurt their families.
