Three weeks were certainly not a long time, even less for Cultivators to prepare themselves.
As such, Kyle had many things to do.
Amongst the most important tasks was to increase his combat prowess.
However, this was, by far, the most difficult to accomplish in the rather short time of three weeks.
Thus instead of focusing on himself, Kyle had decided to continue with the plan he, Beatrice and Yasmine had pursued, with only one difference.
Earlier, he used to go hunting with his small group, and procure soul energy from beasts they had killed.
What had changed now was that he had asked the Blazing Legion unit to help him out.
Each of them was at the Krysal stage, and they would be able to support his grind to procure the most important resource he required to grow; Soul energy.
Even without him revealing what his ability could do, Sven and his small unit of the Blazing Legion had decided to help him out.
