My Lucky Little Skeleton, How About Summoning a Strong Human Being?

[Lords of all people + war between humans and demons + struggle for hegemony in another world + farming. Under the control of mysterious power. Two billion humans and monsters were thrown into the battlefield between gods and demons to fight each other. At the beginning of the arrival, the monster castle will automatically generate 5 low-level monsters of the same kind. For balance, humans will also get a chance to draw heroes for free. Skeleton Soldier Gulou, who was influenced by the remnant souls of humans, 'accidentally' selected the human castle, and was lucky enough to draw the mythical hero Saber. Next, with the help of super luck, I obtained another sub-base [The Great Tomb of Nazarick]. "Saber, I heard that bathing in dragon blood can replenish calcium for bones. Go catch a few and try it out." "The chimera ants actually want to outnumber me. Albedo asked the Death Army to give her some color." When other lords encounter Gulou. "Oh my god! Humans actually formed an alliance with monsters, and the leader of the alliance is still a little skull without a head!"
