Game planner Lin Bufan unexpectedly came to the Sky Continent, where summoners are revered, and obtained the Summoning System of All Realms. I thought I would be able to summon the divine dragon, sword master and demon king from now on, but I didn't expect that the one I summoned for the first time was A-yan, a young dragon that could breathe fire but was afraid of fire. After that, he was surrounded by blood-sick undead knights, socially fearful succubi, and a demon king who just wanted to cook. Faced with academy trials, territorial crises, and conspiracies sweeping across the world, Lin Bufan relied on unique system tasks, unexpected tactics, and trust among his partners to turn a group of summons that were considered "failures" into the strongest legion that attracted the attention of all worlds.
