In his quest to recruit talents to assist him, Duke Xiao promises to share Qin with anyone – including foreigners – who could help him realise his grand ambitions. He attracts the attention of Wei Yang, a Legalist searching for opportunities to test his ideas. After discussing for three days and three nights on end, the two men develop a close relationship and work together over the next two decades to push forth a series of groundbreaking sociopolitical reforms in Qin. The reforms transform Qin into a powerful state and helped to lay the foundation for Qin's eventual unification of China under the Qin dynasty nearly 200 years later.
