SSS-Class Summoner: I only Summon Primordial Spirits

“You have been granted access to the Spirit World; now you must save it.” Laden, a human who was killed and forcefully transmigrated to the world of summoners, was given the sole privilege of directly entering the Spirit World and also the overbearing burden of saving it. In a world where summoners make contracts with Spirit beasts in the Spirit World, granting them world-shattering power. Being able to directly enter the Spirit World was the greatest cheat. With his cheat, Laden slowly made Contracts with Spirit Beast. b But something was wrong; his summons weren't normal. “Why is the blue monkey I found now the Primordial Beast of Combat?” “Why is the tiny snake I saved now the World Devouring Dragon?” Follow Laden as he creates an Arsenal of Primordial Summons all while trying to save the Spirit World. — Description from novelcodex.org
