Over a hundred years ago, the barriers between planes collapsed, and otherworldly forces invaded reality. Countless monsters appeared across the world, leaving devastation in their wake as lives were lost and lands lay in ruins.
Yet humanity's fortune had not run out. Along with the countless monsters, the power to change classes from another world also descended upon reality!
From then on, everything changed.
Everyone could change classes! They gained an ability panel and could become combat-class professionals, killing enemies on the battlefield and roaming freely across the land, or support-class professionals, building infrastructure and bringing prosperity to their communities...
The protagonist awakens two classes, making him an unprecedented genius among humanity.
But just as he awakens, he uses his exclusive "Appraisal" skill to expose the fact that the instructors at Shenfeng Academy are all demonic beasts.
Survival or destruction? How can a genius who has yet to come into his own turn the tables?
