Superior Demon

"First rule, you must defeat the demon before you can challenge the next floor."

A demon suddenly appeared on the opposite side of the room.

Yuan's eyes widened with shock when he saw that it had a black crystal embedded within chest.

"A Superior Demon? Are you kidding me?" He muttered in a voice of disbelief.

"Second rule, you will have an hour to seal or kill the demon. Failure to do so will result in getting kicked out."

"Third rule, you cannot die while inside the Demon Sealing Pagoda. If you 'die' inside, you will be transported outside safely, but you will not be able to use the Demon Sealing Pagoda for 30 days."

"When you're prepared to start the challenge, say 'Ready' out loud."

Yuan closed his eyes and took a deep breath.

He then summoned the Empyrean Overlord and the Starry Abyss.

"Ready."

Whoosh!

The scenery suddenly changes, turning the place into an empty and spacious field.
