Gao Shan and his subordinate officers had made many preparations before entering the Outer Dimension, including, but not limited to, issuing a kerosene lamp to each person.
At first, they seemed useless because it was no longer night inside the school.
Unexpectedly, they became extremely useful here.
The lantern itself was not important, the important thing was the flame within the lantern.
The flame could suppress demons and evil spirits, and as long as this rule was in effect, it didn't matter whether it was lanterns or kerosene lamps providing the light.
Wang Yunxiao had also considered the possibility that the enemy might directly take the lanterns and extinguish the flames.
But it was clear, since the Thousand-Year Dynasty employed this method to fend off the undead outside the city, there must be a good reason for it.
Otherwise, what would be the point of talking about a Thousand-Year Dynasty; it would have bit the dust long ago.
