The three people had already gotten into the vehicle, using props to lighten their own weight without adding load to the vehicle. After receiving a hint from Qiu Ming, Xu Huo asked them about some details regarding the instance, and further inquired about their occasional escort of Dr. Duor up the "Heaven's Ladder".
The three were fairly honest and briefly explained the situation. They came together as six people, plus one "Dr. Duor", but before dark, one companion had died from a deadly poison. The toxin was so potent that the person died before they could even swallow the antitoxin. The other two died respectively in the mouth of a Man-Eating Flower and under the claws of a Mutant Beast. As for "Dr. Duor", when they were attacked by the Night Owl earlier, the three were busy dealing with it and upon turning back, found him missing, leaving only a large hole in the ground inside the Defensive Barrier.
