The dozen or so demons brought by Lan Jingtong did not stay in the Demon Race gathering area.
Once they arrived, the management staff of the Demon Race gathering area immediately led them toward the exit of the Grotto Heaven.
Compared to the various disguise detection cards within the Demon Race gathering area, the detection cards at the Demon Race's exit were evidently more numerous and varied.
If there were really any disguised demons attempting to enter the Demon World through the Grotto Heaven exit,
it would basically be impossible.
No card could pass the detection of the Grotto Heaven exit.
It's simple; any disguise, including bloodline disguise, would have flaws.
In fact, bloodline disguise is the most difficult aspect.
Red cards are practically hopeless, and only one or two golden cards have a chance.
However, those one or two are just single-use cards, which are hard to obtain.
