What happened at the seminar was only a minor disturbance for Lu Zhou.
He hadn't done any research on the tokamak. Therefore, he obviously didn't read the thesis from the Culham Centre for Fusion Energy.
The main reason he attended this academic conference was for the "technical exhibition" segment. He woke up a bit too early on the first day of the conference, so he found his way into a random seminar, causing the previous incident.
After correcting Professor Botham's mistake, Lu Zhou left the lecture hall. He already killed quite a lot of time, so he slowly wandered to the technology exhibition hall.
Compared to the academic conference happening nearby, there was another level of liveliness in the technology exhibition hall.
What was shown at the exhibition wasn't theoretical research results. Instead, it was actual technology.
