Back when Zhao Fu established Heaven's Choice, he had a decent relationship with Soldier Alliance because of Wu Qingniang. However, as Zhao Fu's status rose and he became Great Qin's Legatee's representative, the relationship between them became colder. Zhao Fu also knew that Dong Junhua was interested in Wu Qingniang and did not give him much face.
Dong Junhua had thought that Zhao Fu was Wu Qingniang's subordinate, so he had treated Heaven's Choice quite courteously and helped as much as possible. Of course, with Great Qin's power, there was not much that they needed his help with.
However, after Zhao Fu's status had suddenly changed, Dong Junhua's attitude towards him completely changed, as he most likely saw him as a competitor now.
