When Dalvin chose to break through, it was not as instant as it had been during Qi Refinement for obvious reasons. Each subsequent level had different times for its breakthrough, especially the higher it got.
For Foundation Establishment, using the system, the breakthrough time was one hour. Dalvin sat there and felt his dantian be pushed at all corners by his expansive magic power coupled with his spirit sense, expanding its range by almost double its previous capacity, which was the highest possible to achieve without causing problems.
An hour came to pass while Dalvin was monitoring the process, and he entered Level 2 of Foundation Establishment smoothly. His physical stats had not changed much, but his resistance had gone up, and his magic power capacity had doubled from 400 units to 800.
