At that moment, Yi A-Hua aimed the view at the target of their attack, which also allowed Chu You to see what exactly was happening here.
He saw that about 4000 players were attacking a BOSS...and, wait...what was behind the BOSS? Chu You squinted for a better look and quickly understood. That was a creature's nest!
The nest was a massive tree spirit, an ancient elf, a species under the ancient elf genus. It came to life, its branches swaying, and emitting a gold glow from the underbush. This was a defensive stance.
On top of the massive tree spirit, there were numerous wooden huts. From within the huts, icy arrows were shot at the North American players not far away. Faint noises could be heard from inside the huts. To the reincarnate Chu You, he knew what those were. Those were biotic soldiers of the T5 troop system known as Phantom Shooters!
