Ye Fan does not fear Fu Xi, at least not Fu Xi without Pan Gu's assistance, because there is always a significant gap between their cultivation levels.
But Ye Fan also knows that currently, his strength is considerably outmatched by Fu Xi, and he cannot recklessly underestimate Fu Xi before him. He can only find a way to defeat Fu Xi. If he can resolve both Fu Xi and Nuwa before the tribulation and leave only Pan Gu as an opponent, it might be a very good choice for him.
Yet, before the tribulation, it seems his cultivation is not strong enough to kill or defeat Fu Xi.
"Nuwa is in your hands now, and no matter what you did to her, you must ensure her safety. If she dies, I won't let you off, even when the tribulation is about to come. I will show you the cost! Moreover... if you intend to use some of Nuwa's power against me and Pan Gu, I think you should give up; Nuwa poses no threat to us at all!" Fu Xi said arrogantly.
