People Are Quite Weak, but the Summoned Objects Are Ridiculously Strong.

In this new world called "Mountains and Seas", everyone contains a power called "source" in their body. They can resonate with the natural elements of the outside world and their own flesh and blood consciousness, thus gaining strange powers beyond ordinary people. People who can perfectly control this kind of power are called "source operators" in this world. And this world, which has just emerged from peace, is destined to have imperfections... Unknown beings descend from the sky (Fallen Flesh), the bane left by human greed (orcs), internal conspiracies, and conflicts among foreign races. It is still a problem that people have not completely solved. And our protagonist Renn, due to unknown reasons, the "bottom source" in his body was gradually lost as he grew older, and his graduation test suddenly dropped to double digits like a baby. Even because he mastered the "blood magic power" and had the advantage of obtaining a summoned object through additional summons, he was basically considered a FW destined to be eliminated by society because he summoned a strange will-o'-the-wisp that was deemed to have no skills. But the boat will naturally straighten out when it reaches the bridge, and life still has to go on. Through a series of coincidences, Renn followed the advice of his friends and decided to join the mercenary business and gamble on the future! While busy with life, Ren unexpectedly came into contact with another world and concept, and another group of different partners. Of course, it's possible that everything was arranged.
