Simulation
Editor: EndlessFantasy Translation
"Fireball!"
In the Bell Space, Merlin's Mind Power duplicate extended his finger and immediately, a fireball flew out and exploded.
This spell was no different to any other Fireball. However, Merlin knew that this was just a simulation and it could only exist in the Bell Space. Once out of the Bell Space, there would be no Mind Power duplicate or spells.
"Within the simulation space, Spell Casters could attempt Spell Models without any threats. One could even send in a few Mind Power duplicates to attack each other and test the strength of the spells or Demon Abilities!"
Simulation was the function of the Bell Space!
Perhaps there were more uses, after all, Merlin had only just begun to understand the space. There could be other abilities that he did not know of.
