Helen was in an unfavorable position. The best course of action would be to leave with her three subordinates up the stairs and abandon the three injured team members here, but that would discourage her subordinates.
Noises of banging came from inside the elevator. It seemed that Dong Ni wanted to escape and was trying to force open the elevator doors.
Helen had no intention of helping Dong Ni, hoping he could save himself. Her attention was focused on dealing with Gu Fan. Perhaps Gu Fan was waiting for her to rescue Dong Ni so he could seize the opportunity to attack.
At this moment, Qiao Ya radioed in with a report: he discovered a large hole with signs of recent excavation, presumed to be the doing of Gu Fan and his team.
Qiao Ya thought that Gu Fan, Su Hui, and David besides collecting the research materials might have also taken some equipment. However, while Gu Fan was still here, Su Hui and David had already taken the research materials and equipment away.
