Because his strength was slightly weaker than that person's, he could arrive here earlier than that person, and this time difference was crucial for him. It was almost certain that when that person came, he would also need a vessel, and the vessel should be Hou Yi. As an Ancestral Witch, Hou Yi's physical resilience was the most suitable. Of course, the physical resilience of an Ancestral Witch was still weaker compared to that of the Dragon Emperor's Golden Holy Dragon, which was why that person later had Zhu Bajie abduct the Dragon Emperor. Unfortunately, all of this had long been anticipated by Zhibei, so Tang Sanzang sealed the Dragon Emperor and even transcended Hou Yi.
