In June of the fifth year of the Sui Dynasty (AD 609), Emperor Yang of the Sui Dynasty completed his conquest of Tuyuhun. He was very satisfied and led a large patrol team (including the royal family, civil and military officials, harem, monks, envoys from various countries, and more than 100,000 guards) to Zhangye with the intention of demonstrating the majesty of the Sui Dynasty at the "Universal Exposition". Fu Xilang Pei Yan followed Emperor Yang of the Sui Dynasty on his westward tour, and encountered a strange storm when they arrived at Dadou Bagou (now Biandukou, Minle County, Zhangye, Gansu Province). One hundred thousand troops were buried in the cold abyss. He and the female official Yu Wen Suxin survived by chance, but found out that this was a conspiracy by the "gatekeeper" to use Jiuyou Hanyu to induce evil spirits. Pei Yan discovered that the cold jade core was sealed in Yuwen Suxin's body, and took her on the road to escape. On the way, the Qiang guide Asuna, the Zoroastrian Sa Baoan Noise, Taoist priest Xuanzhen, etc. Helped successively. Pei Yan risked his life to obtain the blood essence of King Gaochang to control the cold poison, but he also attracted the pursuit of the gatekeeper. After experiencing life and death tests such as the burning in Wushaoling and the ghosts in Tongguan, the two finally arrived in Luoyang, but fell into the hands of the powerful Yu Wenshu. At this time, signs of Yinghuo Shouxin appeared in Luoyang City. The gatekeepers were planning to use the luck of the dynasty as a sacrifice to open up the cold abyss. Pei Yan and Yuwen Suxin were involved in a more dangerous whirlpool, and a battle related to the life and death of the world was about to begin.
