The Taiyi Wheel, one of the ten ancient artifacts, has a huge change in history because of the inscription "Taibai overcomes Taichen". The Taibai Empire mass-produced "mechanical beasts" and used its powerful military force to control the land of China. But the ambition is boundless. In order to pursue a territory larger than the land of China, the Taibai Empire intends to take over the world. It was the 99th year of the Taibai calendar. Smoke was rising under the territory of the Taibai Empire, and the battle between the empire and the rebels continued all over the world. In front of the empire's "mechanical beasts" driven by ancient power, a rebel girl stood up holding one of the legendary artifacts, the "Xuanyuan Sword". At that time, the girl's childhood sweetheart became a slave of the empire. As fate would have it, even though the boy's settlement was attacked, he still couldn't help but fall into the charm of mechanical technology. After experiencing various fates of life and death, both of them thought they were separated from each other by life and death, but when they met again, the fate of everyone was also swept into the rolling waves of history.
