Kapitel 1395: Dome of Arturia

Mind communication could save a lot of time and the more powerful a certain mind is; the more time could be compressed.

  There is a limit to how long information could be transferred while at the same time maintaining a different time rate

Hirate could for example talk one hour in the Mind Scape with someone else and when they both open their eyes, only a second had passed in the real world.

But if he spoke the same time of length of information to someone else with a low level mental energy, when they open their eyes, a few minutes might have passed

The more powerful a mental energy that someone have, the longer and the faster they could hold the information

Hirate always found it hard to explain this to people. 

It is not that he manipulates time like Jean but in the mind, information could be transferred faster. Time and Space of the real world is not affected at all.

Hirate take another sip of his coffee.
