The protagonist is thrown into a different world because the cheating device of having a portable space does not comply with the survival rules of this world. This other world has been selected, and even if there is a cheat device, it is not conspicuous. But when traveling through time, the great monk placed it in the wrong place?
Portable Space is still a powerful cheating tool, and it seems to have developed new features?
Have you ever seen a portable space that can be used to upgrade tasks?
The story tells the story of the protagonist being thrown into a different world, relying on a powerful cheating device to conquer all kinds of bad guys and conquer the calm (facial paralysis??) Gong who has a plot to control his younger brother.
