The Dungeon Trial

Kouji pressed on, deeper into the dungeon. The walls of rock appeared to be thinner, the air thick. The deeper he went, the more monsters there were—goblins, giant rats, and skeletal soldiers with rusted swords. None of them were a challenge.

He utilized his power again, imbuing his katana with weight just before collision. The added oomph helped him cut through monsters with no effort at all. With each kill, his speed increased, his control of gravity more acute.

After his twentieth monster was killed, yet another system message appeared.

[Level Up! Current Level: 11]

Kouji paused, feeling the difference in his body. He was stronger, his grip tighter, his reflexes quicker. The leveling system in this world really worked.

Something ahead of him caught his attention, though. A growl of a different kind, lower and more ominous. He moved into a large chamber, where a massive beast lay in wait.

A Dungeon Boss.

A hulking, armored beast with sharp horns and red, blazing eyes. A warning popped into his head.

[Dungeon Boss Fight: Ogre Berserker (Level 20)]

Kouji grinned. "At last, something that's worth my while."

The ogre bellowed and rushed. Kouji took a deep breath, getting low. He contributed his own mass, settling himself into the ground, and then—

He vanished.

Using his power, he reduced his mass to nearly zero, zipping forward at superhuman velocity. His sword glinted as he dropped in a spinning arc.

The battle had begun.
