Before going to the sixth floor, Julian reminded them that they would have to break an illusion to continue exploring the other floors. He also gave them pointers on how to pass this test.
As this psychic attack would drain them of their energy reserves little by little, and since they didn't risk any psychological damage, he wouldn't interfere in this trial; they had to pass this test alone, with just Yelena's buff acting as support.
Julian would then continue to explore the other floors with the remaining students in his group. As for those who couldn't make it, they could go train back on the fifth floor.
When everyone was ready, Julian let them pass through the passage to the sixth floor, and when the door closed, they all received another message.
[To pass to the seventh floor, you need to resist a psychic attack, and your energy reserve must be over 25,000 points. The trial starts in 10 seconds.]
