During the Heavenly Saber Tribe's annual sacrificial ritual, the sinner's son, Li Qing, volunteers to pull out the heavenly saber. According to the legend, the person who pulls out the heavenly saber will unite the tribes. However, no one has been able to do for hundreds of years. He sees people whispering and clenches his fist. "I must pull out the saber and get justice for my father," he thinks to himself. But the miracle doesn't happen. He can't accept it, is this the end?
