Hearing that, Mo Li realized they had been made use of. Judging from Dong Yun's incident, Flower Appraisal must have been determined to get rid of these people on the cruise. However, they didn't want to do it themselves so they borrowed Mo Li and Quan Yu's hands.

Mo Xiao was indeed captured onto the ship and that was the bait to lure Mo Li onto the boat. But what was Flower Appraisal's goal?

The only motive Mo Li could think of was money. Mo Xiao was collecting funds for a movie and the ship was filled with rich people. However, why would an international crime organization need that much money?

Quan Yu also just realized the truth when he reached the 9th floor. He also realized He Yan's role in the whole thing. He Yan offered Flower Appraisal the opportunity to use the Sea of Goddess, while Flower Appraisal helped him take revenge.
