Yan Yong and those guards had never encountered Yun Xiao's most powerful techniques, because they were very familiar with Yan Shi's current methods. Given such a huge disparity in Meridian Qi, there was no chance for them to escape.
However, for some unknown reason, when Yan Shi saw Yun Xiao enveloped by his Meridian Qi, a strange feeling suddenly arose in his heart.
It seemed like back in the Meridian Treasure, he had similarly enveloped Yun Xiao, but the aftermath turned out to be Yan Shi himself being severely injured.
The current situation was strikingly similar to that time, which prompted Yan Shi to feel this way because he couldn't be sure whether Yun Xiao would once again burst forth with power far surpassing his cultivation level.
Yan Shi certainly knew about the type of power Yun Xiao relied on. It was merely an external force, and moreover, it might not last long, let alone be used a second time.
