At this moment, the dormitory was empty and very quiet.
[Do you wish to claim the earthquake prediction device and its manufacturing principles?]
"Yes!" Lin Fan said.
Whoosh!
In the next moment, a completely black rectangular machine about one cubic meter in size appeared in front of him.

There was a huge stack of information on top of the earthquake forecaster.
At the top of the information, there were nine big words—'The Principle Behind the Construction of the Earthquake Prediction Device.'
Lin Fan first sized up the black machine and muttered, "This is the earthquake prediction device, right? It looks like a box."
Then, he picked up the documents and quickly flipped through them.
