A thousand years have passed since the worlds merged. After a hundred years of mortal life and a hundred generations, the era of universal class advancement has begun.
Beastfolk! Foreign races! Instances! Trials! The survival of humanity is at stake!
After turning eighteen, every member of the human race undergoes a class advancement ceremony that determines their fate!
Su Tong, a transmigrator, changes class to [Seal Master] during the ceremony and awakens a System that grants him a god-tier talent.
Boss too strong? Seal it!
Unbreakable curse? Seal it!
Some kind of fairy maiden? Seal her first, then talk.
“Wings of Destruction, the strongest ancient dragon at SSS rank. Huh?! Where’s the boss? Where’s the instance?!”
“All ten rulers of the Ten Emperors’ Hall have gone missing! Is this the collapse of humanity or the decline of morality~”
“Young friend, hold on! My fox clan is willing to offer you our Nine-Tailed Saintess as your maid!”
“Su Tong! Is there anything in this world you can’t seal?!”
“Oh~ I’ve sealed everything already. There’s nothing left!”
If you can’t beat it, seal it. If you can beat it, seal it anyway. How’s anyone else supposed to play?!
