Lord: Starting with Summoning the Regular Army of Earth

[National Blend + Fourth Calamity + Farming + Lord] Matthew transmigrates to a Western fantasy world, becoming a down-on-his-luck prince exiled to a remote, barren territory. Faced with severe problems such as land scarcity, floods, and food shortages, as well as the constant threat from the depths of the Misty Mountains, he is filled with despair. Fortunately, an ancient relic left to him by his mother allows him to successfully summon several goblins. To others, these lowest-level humanoid creatures seem incapable of creating miracles. However, to Matthew's surprise, the souls of these goblins actually come from "Blue Star." Watching the goblin "regular army" chanting slogans, standing in neat rows, and obeying orders, Matthew knows he's got it all figured out. ... On Blue Star, high school student Matthew dies mysteriously in class. A mysterious magic circle appears at the scene, and the school is subsequently sealed off for research. It is discovered that the magic circle can connect with the consciousness of Blue Star inhabitants, allowing them to enter an unknown fantasy world and become the magical creatures summoned by the transmigrator Matthew. Thus, elites from various fields on Blue Star begin to enter this other world...
