I've seen the Snow Dragon enter.

This question is explained in the later episode. Half a month's sneak attack on Shangguan Yan and Sima Changfeng failed. An old man in Guhe Frontier personally said, "I despise fighting with you." "His life is not yours" means that Shangguanyan and Sima Changfeng will take revenge for half a day, and it is not necessary for Gugutian and the frontier old man to do it themselves. I think it's a bit of a screenwriter, because if GuGutian and the frontier fortress old man directly confront each other within half a day, then the whole story will be less suspenseful and not worth watching, just like why the Monkey King in The Journey to the West can't defeat monsters with one hand every time. This layout makes the protagonist of the story more brilliant and the story more exciting.
