Could someone who only knew basic mathematics work on differential geometry in only one go?

Of course not. It would probably take him hundreds of times… trying to take the first step.

This was why when Angor planned to "do it in one go", he ended up lying on the floor with his eyes spinning.

To use his spirit power to make the third slice and create the third surface in his mind space proved to be way harder than he thought.

Most talents would not have much problem doing the first slice, and it would take some time and effort for them to do the second. From the third and on, however, they needed talent and knowledge as well as more time and training.

In his current condition, Angor would need a long time on the third slice.

Days and nights passed. Angor spent all his time in a loop between two conditions: brain exhaustion and lying unconsciously.
