Even Without a Class, I Can Still Slay Gods

Lin Bei transmigrates into a world where everyone has a class, but when it comes time to change classes, he becomes classless. Just as everyone is laughing at him, he awakens the [God-Tier Skill System]. You say you're a knight who can tank monsters? How about [Dragon Cry], which reduces damage by 1% at the cost of 3% of your maximum health? You say you're a mage who can wipe out groups? Try [Winter Has Come] and [Goddess Luo Descends], which deal damage over a huge area and also freeze enemies and boost sword speed. You say you're a warrior with high-burst melee skills? Try [Ruyi Golden Cudgel]. Its burst damage will take you out in an instant! You say you're a priest who can heal and remove control effects? Try [Song of Forgetting Worries] and [Guardian Mechanism]... They remove control effects, heal, boost attack, and grant shields!
