At first glance, Wei Yuan seemed to have given him the power to choose between the two. But in fact, he had no choice. It was impossible for him to return to the hidden Dragon City to help.
Xu Pingfeng's train of thought was very clear. Compared to the elite troops of Yunzhou, the loss of the hidden Dragon City was a pity, but the elite troops were the most important.
After making a choice and abandoning the hidden Dragon City, there were two paths in front of him. The first was to protect the Yunzhou Army and return to Yongzhou or Qingzhou. He would then turn from active to passive and let Da Feng attack the city while the Yunzhou Army defended the city.
The advantage of this strategy was that Da Feng, which had suffered heavy losses, most of the time would not have the troops to take back Yongzhou and Qingzhou. They would choose to recuperate and build up strength, and fight again after the autumn harvest.
