Xu Huo and Nie Xuan had been in the Chaotic Space for almost a day. With such a major operation by the Special Defense Department, it was impossible not to attract the attention of interested parties. Inevitably, some curious individuals would follow, and once they got near, getting inside information wasn't too difficult. Even Yu Qingqing could eavesdrop on the arrangements and decisions of the Special Defense Department. Defense props were sometimes ineffective.
In just a day or half a day, players from not far away would have arrived, especially some larger Player Organizations. Although they did not attempt to enter the Special Defense Department's perimeter, they still exerted some pressure.
Whether it's player organizations or unknown Super Evolvers entering, they might not gain much, but causing trouble would not be difficult, especially since they're unaware of the situation.
