Collapse, world modulation mode

Ye Feng traveled to St. Freya's Academy in Honkai Impact 3rd, but why couldn't they see him?
No matter what Ye Feng did, they just did their own assigned tasks.
"Current location: Saint Freya Academy... Can we open up new maps? Let me see, Yae Village, Golden Courtyard, and Black Tower Space Station."
Is this a game-like world, and am I the "administrator"?
Not only are there the Big Three from my school days, but there are also Big Duck and Auntie Ya? Yay!
In order to find out the correct way to open this world as soon as possible,
Ye Feng went to the office to discuss academic matters with the Herr of Truth, Dayaya.
Teaching Kiana homework in the library,
In the Valkyrie dormitory, he tutored Mei in front of Kiana.
Fu Zhuangshi was right, it was really hard.
.......
I don’t know how much time had passed, but Kiana, who was sleeping in class, suddenly “woke up” and stared at the principal sitting on the desk in a daze.
