The Ghost General is a ghost entity comparable to a Foundation Establishment Cultivator.
The evil ghost that appeared in the Ancient County city back then was a Ghost General, but it was merely a Ghost General artificially created through an array, far less powerful than a true Ghost General.
Besides the Ten Thousand Ghosts Banner, Mo Xuanyu actually has a Divine Soul defensive magical treasure, otherwise, the Soul-breaking Cone wouldn't be halted.
This is the difference between Yang Zhenshan and Mo Xuanyu; look at Mo Xuanyu's magical treasures and then at Yang Zhenshan's, there's really no comparison.
Though Yang Zhenshan occupies Spirit Origin Land, he is still far inferior to Mo Xuanyu, who hails from a major power as a Foundation Establishment Cultivator.
This is also why he had previously refused Xuanzhen's suggestion, and his attack on Mo Xuanyu was not truly intended to capture him but merely to probe, otherwise he wouldn't have retreated so swiftly.
