The spirit snake of Qingcheng Mountain appears and wants to imitate Bai Suzhen and come down the mountain to repay his kindness. The seven emotions and six desires and the inner words of Buddhism cannot be taken into consideration at the same time. How to choose?

From Jincheng to Chang'an, from ignorance to enlightenment. "If I want to use you to sacrifice to heaven, would you be willing?" "Is my life meant to be sacrificed for love or for the common people?"
