A bright light flashed before returning to normal.
Fang Jinyu wasn't surprised at all by his natural breakthrough.
If Fang Jinyu hadn't wanted to understand the essence of the Core Formation stage section of the lightning spell, he might have broken through rank 5 in the Core Formation stage!
However, doing so might limit him.
Grandmaster Meng had repeatedly reminded Fang Jinyu that cultivation wasn't just about improving his inner energy. Cultivation bottlenecks were a matter, and cultivation technique bottlenecks were another. If one had improved their inner energy without fully understanding the cultivation techniques, then it would only consume the cultivation foundation of a first-grade core that one had painstakingly obtained.
Since his "Senior Brother Meng" had said so, Fang Jinyu naturally had to be steady and careful. He didn't dare be careless.
It was because once he had chosen the wrong path, there was no turning back!
