Chapter 454: Deduction, Examination, Experiment, Verification

On the morning of July 19, Jin, Elsa, and Saki went to Hourai Island. Berthie returned to Kartze Village, where Reinhardt was waiting for her.

“Let’s say I put several big round stones into a box. Well, after it’s filled with round stones, would I still be able to put something in the box?”

“Hmm? But if it’s ful
