章 337: B -Rank Monarch Core

Three days later inside the dungeon...

Evan was sitting cross-legged on the floor of the boss room. A large mana vortex was spinning above his head, attracting large amounts of mana from the surrounding.

The size of this mana vortex was very big compared to previous mana vortexes. It was around 30 meters in diameter and was covering a large area of the room.

Evan's body was absorbing the mana drawn by the vortex like a bottomless pit as his core advances to the next rank.

After five minutes of continuously absorbing mana, a notification flashed before his eyes.

(Your prime core reached the B+ rank)

Woosh!

As soon as the notification flashed, his prime core released a great amount of energy that spread throughout his body and began to nourish the cells of his body, making his already terrifying physical body even more terrifying.
