Nuwa: Fat Cat, you can usually bully those innate divine beasts and innate gods who have no backing. Who told you to insult the saint?

Don't you know your own capabilities?

Fat Cat, I don't mind if you usually go fishing, catching birds, or raiding bird nests, but who told you to go and catch Kunpeng and Dijun, and plunder the dojos of the primordial gods?

Nuwa: Fat cat, you're getting upset just because I said a few words to you.

Fat cat, why are you raising your paw? Are you going to hit me?

Bai Chen: Meow meow, I, the great god Bai Chen, love to reason with others and persuade them with virtue!

The innate gods' faces darkened, because Bai Chen's principles and morality could lead to death!

The sacred flame shines brightly!

All my disciples, meow meow meow meow!
