Lan Jing, a young man from Nanliang, went north to practice, which coincided with the "Heyin Incident" in the Northern Wei Dynasty - the powerful minister Er Zhurong massacred more than 2,000 clan officials. He rescued Yuan Yuyi, an orphan girl of the Yuan family, from a sea of blood in a mountain of corpses, and was involved in the turbulent whirlpool of the struggle for hegemony between the north and the south.
The Northern Wei Dynasty split, and the Southern Liang Dynasty and the Northern Expedition were launched. Lan Jing followed the famous general Chen Qingzhi and led 7,000 white-robed troops to the north. They fought in consecutive battles and captured Luoyang for a time. However, the Southern Liang Dynasty was divided and Yuan Hao was suspicious, so the Northern Expedition failed. Lan Jing was captured in the Battle of Hanshan and separated from his best friend Chen Hao.
Gaocheng of the Eastern Wei Dynasty wanted to take over the Wei family through Zen, so he imprisoned Lan Jing in his mansion. With the secret help of the Buddhist craftsman "Half-faced Buddha" and the Yuan family's old tribe, Lan Jing assassinated Gao Cheng on a thunderstorm night. At the same time, Hou Jing rebelled, Nanliang Taicheng was besieged, and the world completely fell apart.
Lan Jing, Chen Hu, Yuan Yuyi and other young people grew up in the flames of war, and witnessed the struggle and perseverance of individuals in troubled times with swords and blood. Plots of power are like chess and human lives are like grass, but they are still fighting for a glimmer of light for themselves and their loved ones in the cracks of history.
