Lin Junzhao's words were like a jarring bolt that harshly awakened Pei Yan within. She was right; ever since awakening his ability domain through Lin Junzhao's training, he had only used it once more against Shitang Longsi, only to abandon it afterward. The reason for this neglect wasn't just because he later incorporated more new abilities, diversifying his combat styles, or the significantly enhanced computing power following his absorption of a supercomputer, allowing him to detect enemy resonance frequencies without the domain's boost.
The main reason was that employing the domain drastically increased mental exhaustion. Although his body could endure a battle, mentally he was exceptionally fatigued, severely affecting the sustainability of combat. Weighing the pros and cons, Pei Yan found it unworthy, hence his discontinuation of it.
