Ye Fan and the six others were unaware that the underground boss, Boss Zuo, whom they had never met, was filled with hostility towards them.
The reason was simple: Boss Zuo was displeased because he wanted to meet the seven of them, but it didn't happen.
Ultimately, Boss Zuo blamed the seven for only being first-rate fighters, but in the Underworld, while fighting ability is important, it's not the decisive factor. Connections and relationships can determine a lot of things. Many times, problems can be solved without force—this is the capability and skill of an experienced underground boss.
From Boss Zuo's perspective, Ye Fan and the other six were being shortsighted by disappearing without waiting for his summons, which he considered foolish.
Initially, Boss Zuo wanted to recruit the seven, but now it seems that all those thoughts were in vain.
The reason Boss Zuo felt this way and got angry was because he didn't consider Ye Fan and the others very important.
