During the period of Warring States, seven countries fought for the only hegemony. King Qin's army was invincible and won many diplomatic victories, eventually annexing other countries. However, where King Qin's army went, there were many corpses and thousands of miles of barren land left. The people found it hard to live on and they were complaining.
