An ordinary army just could not match the fighting abilities of the wight army summoned by the wight sorcerers.
What terrified Master Yue even more was the position at which the wight army had appeared.
The bodies of the wights were not afraid of life or death. They were a peculiar race that had transcended life and death. As long as the summoning power supplied to them remained unbroken and undrained, they would continually clamber up from the ground. What was even more horrifying was that the wight army did not fear losses. Even if they were beaten into a disarray, they could still clamber up from the ground once more. Further, all the soldiers that they killed would be transformed into new wights once they breathed their last.
This cycle made the wight army grow continually. It was almost impossible to exterminate them.
Unless they could find the sorcerer using the Summoning of the Wights and interrupt him, it would be an endless disaster.
