Time ticked by, minute by minute. After two hours, sure enough, a man looked left and right, then slipped into a records room, stayed for a bit, then casually walked back out. Su Xuan knew this guy was scoping the situation. These people really were damned smart, didn't expect them to be this cautious.
There were actually very few people on the fourth-floor lab, and one of the rooms even had a hound. After this guy reached the corner of the wall, he deliberately squatted down to smoke, and then that wall suddenly rose up. The moment the wall lifted, he slipped straight inside. Watching this scene, Chen Chuyu was completely stunned, staring at Su Xuan, clearly not expecting there to be a hidden chamber here.
"The rabbit showed up? You wait here for me!"
