Seven years ago, Beidi's army of three hundred thousand warriorrs invaded Zhengyang Pass and was repelled by the Meng family's army. In that battle, the former King Xuan was killed, Meng Yuan was seriously injured, and He Yuanshan, the general of Beidi, was also shot and killed.
It was a general knowledge that the two sides have lost most of their troops and lost their generals.
Therefore, after the war, the two warring nations signed a ten-year peace treaty, stipulating that the two countries would not go to war with each other for ten years, and they would recuperate.
Now, there were still three years before the ten-year contract, but Bei Di unilaterally tore up the contract, and an army of hundred thousand attacked Jinyang Pass. The Dasheng defenders were caught off guard, and Licheng was overran by the Beidi army overnight.
