Seeing that the three had not emerged from Lin Yun's room for a long time, the teacher who had been hiding in the shadows felt something was amiss. He promptly dropped his cover, walked up to Lin Yun's room, and knocked on the door.
"Who is it?" Lin Yun called out loudly upon hearing the knock.
"I'm your class teacher. I heard some noise in your room just now. Open the door and let me see," the teacher outside replied.
'The main event has arrived.' Lin Yun silently looked at the three men, their faces black and blue. From his gaze, they understood his unspoken question: they knew what to say, didn't they?
The three nodded furiously. Seeing this, Lin Yun gave a slight smile and walked over to open the door.
