Summary of Solo Leveling Manga Chapter 154
A practical dungeon exercise takes the academy class into a real low-rank gate under supervised conditions. When the exercise goes unexpectedly wrong and the supervising hunters are incapacitated, Su-ho takes command of the class with quiet authority that leaves no room for argument. He clears the dungeon and gets everyone out safely in a way that makes the gap between him and his classmates impossible to ignore. The academy administration has a difficult internal conversation about what exactly they are supposed to teach this student.
