Bai Jin recognized this uninvited guest; she was the adventurer covered in blood whom they encountered earlier in the forest.
At that time, Yang Yu had them leave first, while he stayed behind alone to look after the adventurer.
Bai Jin had sensed something unusual about Yang Yu's behavior back then, wondering if this could be a trap...
Yang Yu chose to stay behind alone because he likely detected the trap and did not want to delay the group's support, hence instructing them to leave first.
Now, with this adventurer appearing here nonchalantly through the transmission tunnel, it proves she indeed is an enemy.
Bai Jin immediately shifted her aim from Blala Doren to the Red Blade Doron in front of her, quickly firing several Frost Ice Arrows from her magic array.
Red Blade Doron spread her claws, and with a few flashes of light, all the flying Frost Ice Arrows were shattered, disappearing into countless ice crystals in the air.
