Ye Tianfan decided that when the opportunity arises, he will return to the Zero Plains and then look for Qi Feiyun as mentioned by the final monster. Of course, Ye Tianfan is not the type to search on his own but intends to go through the Great Yama!
Since the final monster wanted to send him to the place where Qi Feiyun is located, it proves that this Great Yama knows Qi Feiyun's location. Given this, even though Ye Tianfan is somewhat displeased, he still has to cooperate with the Great Yama, because currently only the Great Yama and the final monster know Qi Feiyun's location.
Furthermore, Ye Tianfan knows that if he wishes to find Qi Feiyun, one of the final monster or Leader Ming must stay alive, and this matter cannot be disclosed to his master and others, because he has no reason to spare their lives!
