It remains unknown how exactly they go about it.
"Yes, these people have countermeasures, and that is to hide. Most of the demons here launch their attacks at night. During the day, if demons attack, they will be discovered by people. When many people gather together, the suppression from the Qi of Humanity will be very strong, and there will also be help from kind demons. Attacking during daytime is the worst strategy."
"Therefore, most demons choose to attack at night, and the countermeasures of these small kingdoms are 'watchmen'!"
Old Tortoise explained.
"Watchmen? What do you mean by that?"
Yibai was interested.
"True Dragon, these so-called watchmen are people within these small kingdoms who have cultivation. They carry special drums and gongs, and if they detect a demon invasion at night, they will sound their drums and gongs. The instruments are specially made, their sound like thunder, which can make the demons feel disgusted and thus retreat."
Old Tortoise said so.
