Joshua contacted Realius which allowed Realius to teleport Joshua back to his Reality Domain.
As usual, Joshua stayed inside Realius' reality domain. After all, Realius' reality domain provided him with more than enough facilities to improve his strength. Not to mention, the aura inside the reality domain was far denser than most training grounds.
If not for the fact that Realius needed Deus to stay in the Manipulator's Academy as a transfer student, it would be a lot safer and faster for Deus to improve his strength inside the reality domain.
Not only there weren't any dangers in the reality, but Realius could also even create any scenes within his reality domain such as a scene that would allow Deus to improve his battle experience.
