Enter the copy - unknown campus
The A-level dungeon suddenly turned into an SSS-level dungeon. Thousands of players died there. How could an A-level dungeon kill so many people? Because it was not an A-level dungeon at all. The system was also replaced. 31 Strong people entered this dungeon, but only four people could survive. Of the more than 2,000 students on the unknown campus, no more than 10 survived. The final big boss turned out to be a little girl.
