I want to know the answer to the following question:
With what action did the Qin bring together the Chinese Warring States?
All the background I'm provided with is that "Two former rebel leaders, Xiang Yu (d. 202 BC) of Chu and Liu Bang (d. 195 BC) of Han, engaged in a war to decide who would become hegemon of China, which had fissured into 18 kingdoms, each claiming allegiance to either Xiang Yu or Liu Bang.". Is that enough to answer the question?
