Liang Cheng's timing in leading the two hundred riders to charge was perfect. However, this was also a stroke of luck, as initially, Liang Cheng hadn't planned to rush in and rescue the Sword Saint.
Most of the time, Demon Lords acted based on two primary motivations: one was vested interest, and the other, personal whim or fascination.
Saving their lord and ensuring his safety wasn't merely a matter of self-interest. There was a high probability that if their lord met with an accident, all seven of them would collectively perish.
As for the Sword Saint, Liang Cheng hadn't expected him to so recklessly charge headfirst into a thousand wild people. Not only Liang Cheng, but even General Zheng, who had just reached the city gate and finally had a chance to look back, was startled.
