Ray Latens is an aspiring Arcanist who struggles to cast any decent magic on Earth, where Mana density is extremely low. By a twist of fate, he finds himself in another world, the place that is full to the brim with Mana, but there's one tiny problem. . . His new home is inhabited by barbarous people who call themselves cultivators but ironically lack any decent culture. They use the abundant Mana of their world not for magic but to enhance their bodies in the most inefficient way ever, they have a primitive society where the strong is always right, and they are arrogant beyond any reason. If only consumption of suspicious drugs was the end of their stupidity. . . Ray has never expected that a legendary Higher World would be such a shithole. But as the saying goes, beggars can't be choosers. As a benevolent Arcanist he is, Ray will show these plebs how to cultivate magic properly.
