This reveals the defense vulnerability of Celestial Essence City.
Even when there are no demons approaching, Celestial Essence City still allows the flow of people inside and out.
After all, there are visible differences between demons and humans, so there's no worry about them sneaking into the city.
However, the natives couldn't have imagined the existence of hostile players, who could infiltrate through some disguises and secretly carry out their plans.
Fortunately, the target of this group was clear—they were not aiming to destroy Celestial Essence City but focusing on dealing with players from Earth, which kept the problem from this vulnerability from being too severe.
If Wang Zhifan happened to be near these players from the Otherworld, relying on his exceptional perception abilities, he could likely identify these potential threats because he had encountered this group during the chaos in Shuyue City and was already somewhat wary.
