「That is what I mean. The boy possesses the【Status Effect Resistance】skill, so he is likely enduring the effects of fatigue and sleep deprivation. He even seems to possess the【Surpass Limits】skill as well.」(Zadiris)

As Zadiris was saying, with the skills that Vandalieu possessed, even an infant’s body could endure the effects of fatigue. Even to the point that Vandalieu himself wouldn’t really notice that he was pushing himself past his limits.

Because of his resistance skills, even if he was fatigued his body still moved normally, so he would be under the impression that he was still fine. That was why he could endure being sleepy, so even the time that he did spend sleeping so that his development wouldn’t be negatively affected grew shorter, as he would always think,「This much sleep will be enough.」

But the resistance skills only allowed him to endure this. They wouldn’t remove his fatigue or help him quickly recover from it. And so, in reality, his fatigue was accumulating.
