Apocalypse: I Slay Demons in the Demon Realm

Countless years ago, demonic beasts attacked Blue Star.

The first mysterious individuals suddenly appeared among humanity. As they helped people repel the demonic beasts, they also passed down their body-tempering techniques.

Now the demon race had been driven back to the Demon Domain, but they still kept trying to attack human cities.

At that point, humanity entered the Demon Domain through black holes and built castles, determined to keep the demonic beasts from crossing over.

Yuan Qing transmigrated from Earth and became a citizen of the Dragon Kingdom on Blue Star.

After graduating, he too joined the defenders who entered the Demon Domain to protect humanity.

Then his Summoning System awakened.

Demon Domain, tremble before me!

"That human summoner can summon thousands upon thousands of demonic beasts! No, hundreds of millions!"

"Good heavens, run! Yuan Qing, that human who kills demons without a second thought, is here!"

"In this apocalypse, only Yuan Qing of the Dragon Kingdom can defend Blue Star alone!"
