I've seen a lot of people confused about the skill, so I'll leave some simple explanations here.

1° The editing skill does NOT use SP or MP! The protagonist's SP drops quickly because of his weak body at the start of the story. The skill pushes his body to its limits, making him tire quickly (and his body deteriorate).

2° The level of the editing skill does not increase the duration of the edit, only its power. For example: how many statuses he can edit simultaneously, and the system also releases new features as the level goes up.

3° From a certain point, it's not just the [ Editing ] skill that will increase his strength. His unique evolution path also greatly increases his power.

4° The [ Edit+ ] skill has nothing special about it. It only increases the duration of the edit and does not increase its strength. 

5° The possibility of editing skills and raising them to level 10 has something to do with his new unique evolution(spoiler), but his editing skill will interfere with this in the future.

6° The use of the skill is unlimited. He can activate it again as soon as it deactivates. However, as I said, if he sets a Status too high, his SP will decrease quickly because his body can't take it. (Example: If he raised his Status to 1,000,000 and tried to attack something, his body would disintegrate even if he raises his defense as well )

That's it.
