Kapitel 540: Chapter 320: The Mathematical Legacy of the Unlucky Ghost

On the podium.

Zhao Yi looks at the student roster in his hand, ready to take roll call just like any other teacher, going down the list calling out names. But when he looks up at the classroom, he realizes something is amiss.

There are way too many attendees!

"Particle Boundary Theory Overview" is a course that is open to only a hundred elective slots. Conducted in a large classroom at the School of Sciences that can hold two hundred people, there should ordinarily be many vacant seats. Yet, there are clearly more than a hundred people present, occupying more than two-thirds of the room at a cursory glance.

[How many people are in the classroom right now?]

Using Causality Law to compare the limited seats with the number of people, he gets his answer immediately--

[Answer: 159 people.]

"Just as I thought!"

"It seems a lot of students who didn't register for the course came to listen as well..."

It's not just students!
