简介:In the past, Jianlu did not leave Yutian because he was worried that it would give the Ming Dynasty too much preparation time. The Ming Dynasty's nine-sided elites would rush to the aid of the capital. However, in the Battle of Songjin, the nine-sided elites were burned to the ground. Now only the remnants of Ningyuan and Shanhaiguan are left. So Jianlu no longer worries about this.
