During the reign of Emperor Huizong of the Song Dynasty, the Pang family in Gusu was copied because of an ancient painting. The young man Pang Qingyan, bearing a blood feud, went north to Bianliang, entered the painting academy, and got close to the emperor, using his pen as a blade. But the war broke out in Jingkang, and pictures could not save the people. He put down his paintbrush and picked up his sword to defend the city. Paintings burn, the city is destroyed, but the character is immortal.
