First, Wu Dalang is weak and does not have enough combat capability, let alone fight back;
Second, Ximen Qing is a strongman, intertwined with various forces and relying on each other. We don't know if there is anyone above Ximen Qing, but according to experience, it is unscientific if there is no one so confident above;
Third, Pan Jinlian, as the external reflection of the contradiction between Wu Dalang and Ximen Qing, is the energy release center of both. The competition for Pan Jinlian actually reflects the competition for interests, reputation, market share and energy resources.
Fourth, Song Wu, as the most solid backing of Wu Dalang, did not appear at the right time and place.
