Zhang Lisheng's calm and cooperative actions had somewhat dispelled the nervousness of some officers.
"If you're really a scientist in the bunker, why didn't you notice in advance when you go in and out?" The sergeant in charge of the duty asked in a skeptical manner but he still picked up the scanner to scan the face of the skinny and bald young Asian man in front of him.
Very soon, the computer screen connected to the scanner confirmed Zhang Lisheng's words. The sergeant breathed a sigh of relief, "Dr. Zhang Lisheng, looks like you often leave the bunker for a long time, so it's no wonder you still don't know what happened."
He did not order his men to lower their guns but instead, he asked with a slight amiable tone as he pointed at the three girls. "Who are they?"
"My girlfriend, and two good friends. They are students from Harvard University who came to visit the island. I'm just taking them to my lab."
