Before, Qian Xing sought help from Da Han to rescue Ba Qi.
Da Han, as promised, helped him find Ba Qi. Then, both were startled away by the Undead Master.
Although Qian Xing did not achieve his own purpose, Da Han indeed fulfilled his promised part, so after coming back, Qian Xing stayed with Da Han's fleet and did not leave.
Qian Xing did not show himself publicly either, becoming a hidden asset for Da Han under his arrangement.
Seeing Da Han's "struggle" in pursuing Feng Lian, Qian Xing volunteered.
Da Han refused through voice transmission: "There is no need for that."
Qian Xing's promise of "fully assisting in battle" was hard-earned; he wouldn't waste it on Feng Lian. Using a Holy Domain Level force to take Feng Lian's life was not worthwhile.
Da Han decided not to personally participate in the battle, and within the Holy Domain's enclosure, he flew back to his flagship.
With a wave of his hand, he ordered everyone to pursue the Divine Wind Pirate Group.
