The Dark Coalition group that had annihilated Gong Ge's people was none other than Ayshan's henchmen, and they were from the Gate of Fear.
Ayshan was a mad villain that had his own corporation, but he often acted on his own and would only care about his subordinates whenever he needed them. Else, he would totally disregard them.
Furthermore, it was normal for them to operate illegally as they belonged to the Dark Coalition. Being a Hellfire Ifrit himself, it was absolutely normal for Ayshan to eliminate any of his people without any valid justification.
Which was why Gong Ge was terrified of him as he had further strengthened his presence at the Blood River Realm. As the number of people from the Gate of Fear grew higher, nobody was sure whether there were only five A-tiers with them.
Both of them were indeed seemingly sending themselves to seek for their own death!
