"Look, there he is. Let's keep our voices down and follow him to see what he's really up to," I whispered as I peeked out the dormitory door and spotted Zhang Qingyu's figure. He was staggering, like someone groggy with sleep or stumbling like a drunk.
"Shh, don't get caught. Let's hurry up and follow him," Wang Duo whispered back at me, lowering his voice, and then he gestured for silence before quickening his pace and stepping ahead of me.
Perhaps because Zhang Qingyu was moving so slowly, we almost caught up to him before he reached the end of the hallway. The distance between us was about ten meters. Since we were making our steps soundless, we hadn't been noticed. Of course, Wang Duo and I dared not get any closer, as we risked being detected.
Just as Zhang Qingyu was about to reach the staircase, just as I was contemplating his next move, he made a sharp right turn and ducked into a doorway.
