Ye Fan doesn't remember who Lei Zu's daughter is at all, so there's no way to talk about helping Lei Zu find her daughter.
Lei Zu, however, is very insistent, wanting Ye Fan to help her find someone. Ye Fan can also feel that Lei Zu's power is dwindling. Apparently, Lei Zu has sacrificed a lot, maybe even her life, to escape from the control of Pan Gu and Nuwa's avatars.
Ye Fan said, "I can't help you find your daughter, but try to take me to see Li Yunhuo first. If I can find some clue from him, maybe I can help you!"
"You're not just trying to use me, rather than genuinely help me. Why should I trust you?" Lei Zu said angrily.
Ye Fan shook his head and said, "Incredible. You don't seem to hate Li Yunhuo very much, which I find strange. What's the relationship between you and Li Yunhuo?"
"What are you talking about? I don't understand. You'd better not slander me. I have no relationship whatsoever with Li Yunhuo!" Lei Zu said to Ye Fan through gritted teeth.
