126 Class.

Shi Lang was sleeping in his room when his communicator vibrated. The youngster woke up quickly and found that it was a message from X. He got up and after taking a shower got dressed in the attire of this place. A black spacesuit with a trace of white on the abdominal and the shoulders. There were no markings on the suit whatsoever. 

Before going out of the room, he memorized the map on the back of the door. After coming out, he followed the directions and came to a place that looked like a classroom from the outside. At the moment inside the room sat thirty people. Shi Lang saw X standing at the podium gazing in front of him.
