After the recent experiment, Fang Hao understood how to operate the Demon Space.
It wasn't possible to store items out of thin air through intention; physical contact was required.
*This detail indeed matched the characteristics of the Book of Lords. Whether it was devouring another person's Book of Lords or recording scrolls, physical contact was always necessary.*
The same applied to storing items.
The storage space didn't specify its exact size.
But based on the wooden table placed inside, it could be roughly inferred as a rectangular space about five meters long and four meters wide.
It resembled the area in the Demon Stone Cave where the desk was placed earlier; the dimensions were similar.
All in all, it was a small room of over 20 square meters, with a height close to three meters.
You could decide what to store yourself.
However, living creatures and troop types couldn't be stored there.
*If they could be, it would surely come in handy for kidnappings.*
