The opening of Little Cave Heaven was a grand event in Huaxia, but foreign Innate strong people would not miss this opportunity.
Similarly, some Martial Artists who weren't in the Innate Realm also wanted to sneak in; this was a rare opportunity that occurred once in a millennium.
Although there were Cultivators at the Gathering Spirit Stage overseeing the event, for some who were relatively skilled at hiding their abilities, this really wasn't much of a challenge.
In Tang Feng's eyes, the combat power of those at the Gathering Spirit Stage here might not even be on par with some Innate Realm Martial Artists.
Honestly, it was quite difficult to manage even this under such circumstances.
The allure of Little Cave Heaven drove people mad; the flood of Martial Artists into the passage as soon as it opened was a clear sign of the brutal struggles that would occur inside.
