Global: Good Grief! How Did I, a Mage, Become Invincible?

As games merge with reality, game dungeons and secret realms begin appearing in the real world.

Blue Star enters an era where everyone can change classes!

At the class-awakening ceremony, Liu Yu's System comes online!

Others awaken intermediate talent skills the first time they successfully change classes? I have a god-tier talent from the start!

They say only Archmages can use Forbidden Spells? I can cast them at Lv. 0!

"Liu Yu, class change successful. Your class is... your class is..."

"Sleep Mage!"

At the same time, an electronic System voice rang in Liu Yu's ears!
