Years ago when Zhao Wang Lei had just ascended the throne, Qin had attacked Xin thinking that such a time when the Emperor was still new and inexperienced would be a great time to capture his Empire and annex the territory.
However, the Qin Empire forgot that the Emperor might have been new and inexperienced, it was not he who managed and commanded the military. It was Li Clan who did that and Li Clan had always stayed well prepared for the enemy's attack.
The first attack had been handled very well after a moment of surprise which had come because of the sudden attack.
However, it was just the beginning of a war that went as long as three and a half years without any break.
It was after this long period that both sides suddenly realized that the war was not doing any good to both sides so it was wiser to come to some mutual compromise and end the war.
