The army led by Rong San had already quietly set out for Huaiyang County on the same night.
And Huaiyang County was a city recently occupied by Nanjiang Country.
Taking advantage of Yelü Nan leading a large army to attack Tongcheng County, he began his assault on Huaiyang County.
By dawn, he had successfully reclaimed Huaiyang County.
He then cleaned up the aftermath as quickly as possible without letting any news leak out.
When Yelü Nan returned dejectedly with the remaining half of his army, he ordered the city gates to be opened to let them in.
Then, he trapped them inside and eliminated them one by one.
At that time, the battle was fierce, and the fighting was thunderous.
And the army led by Rong San was one of the most elite forces of Yunlong Country, so they hardly broke a sweat before they had them all subdued.
It was then that Yelü Nan realized Yun Shangyuan was not as simple as he had imagined.
