The Warring States period in China endured a never-ending dragon of conflict for five hundred long years, watching the birth and death of kingdoms as rulers and military leaders competed for power. As a result of this brutal cycle, seven powerful states emerged victorious.

However, Piao is unexpectedly taken away by a royal official to serve in the palace court, leaving his friend behind. After a violent overthrow, Piao returns to Xin, close to death, with a vital task that leads him to meet King Ying Zheng, who looks hauntingly similar to Piao. While Xin forges his own path to greatness amidst the gory history of China, he faces numerous obstacles in his quest to become a legendary Great General during the Seven Warring States era.
