Regius was understanding something the more that he was walking around and it was that he may have been wrong to come here. He was already in the fifth rank of mana practice and like many of the fourth-year students, he could fight enemies several tiers above himself reliably and by the time he digested everything his mana had just eaten he would have access to every element then the only thing holding him back would be staying at the school.
After he was done in the core world, it may be time that he explored portals. He could strengthen himself rapidly as he prepared to venture towards the demon homeworld to rescue his mother before he returned here and could guide humanity on a fresh path, a stronger one.
