The King of Summoners in an Online Game

"Well, this BOSS is a bit strong. Let's summon a stronger one to play with it." "I heard that this copy is very difficult, but why are the monsters that appear in it not as strong as those I summoned?" "All players in the server regard me as their enemy. If that's the case, then summon millions of elite beasts to play with them." "Want to go up to the sky and look at the moon? It's okay, I can summon the flying dragon." "..." This is the legendary story of a summoner.
