Story During the Warring States period in China, danger seemed to lurk within the Han State which is seen to be the weakest of the Seven States. It is under threat from the more powerful Qin State while the ageing Han King is losing his grip on power due to internal power struggles. The greatest threat is the Great General of Han, Ji Wuye and the Four Fearful Warriors of Nightfall, each specializing in military, finance, politics, and espionage.

The Ninth Prince of Han, Han Fei, hopes to create a new world with a stronger Han State that can overcome its internal problems and withstand the pressure from the Qin. He forms Quicksand with Wei Zhuang, Zhang Liang, Zinü, and Nong Yu, who support the Prince in realizing his goal while helping to combat the forces against him.
