"You," Xu Huo pointed at Tong Jian. "Try walking out the door."
"If you aren't a ticket player, once the instance is closed, you can't leave either," Kong Cheng said.
"Seeing is believing," Xu Huo simply didn't believe him and insisted that Tong Jian do as he said.
Tong Jian looked at Kong Cheng and, after getting a nod, he walked toward the door. Just like the ticket players, he was stopped by an invisible barrier, and hitting the glass and walls next to him was ineffective.
"Are you satisfied now?" Tong Jian turned around and asked.
Xu Huo then motioned for the Kong siblings to move away from the elevator, and with Dr. Deng as his hostage, he headed toward the elevator.
While they walked, Dr. Deng, sweating, said, "Be careful, don't cut me..."
"Shut up!" Xu Huo yanked him, dragged him into the elevator, and said to the Kong siblings, "You stay here. If I find the elevator running, you know the consequences."
