The Ultimate First Class Sign-In System

Traveling through the ultimate class, bound to the sign-in system. I just want to watch the show, but my strength doesn't allow it. Wang Dadong is still complacent about breaking through the 10,000-strong battle force. There are so many SSS-level martial arts in my warehouse that they are useless. Teacher Tian Xin's safety? I signed into a time and space barrier without any trouble. Until that day, Black Dragon's men surrounded the classroom, I yawned and took out the sign-in gift from the table... "Hey, you guys are blocking me from the sun."
