Gaming Empire System

Wallace transmigrated into a magical world dominated by powerful "Nobles". These Nobles possessed the ability to control mana and were given magical dungeons by higher beings. By feeding these dungeons with magic crystals, and human blood, the Nobles could strengthen their lands and people. The Nobles relied on people with magical abilities called mana users, like knights and wizards, to provide them with the necessary magic crystals. As more individuals with mana emerged, the Nobles gained greater influence and expanded their territories. Wallace was born as the illegitimate son of a Noble, and was thus not considered a "true" Noble. Tragically, his entire family was killed before his eyes due to their ancestor's actions. The one responsible, a lady, threatened to return and make his life even worse because of his resemblance to his ancestor. However, this traumatic event also awakened a hidden power within Wallace - the Gaming Empire System. I am a fan of Black tech internet cafe system, I just want write a similar one.
