Li Yue traveled to the devil's castle, and he was not a cool vampire or a mysterious magician, but a bald brain spirit?

Fortunately, the brain spirit has the ability to perceive thoughts, move objects through the air, and shock souls... at least it can be considered a magical creature.

Li Yue, who has unlocked the "Demon's Encyclopedia", will start as a brain spirit, collect strange monsters, transform the inner demons, summon monsters from other worlds... wander in chaos and darkness, and climb to the top of the Demon King's City step by step.

The game merges reality, and monsters are rampant on the blue planet.

Fortunately, everyone can awaken a profession.

On the day of the ceremony, Qin Yu accidentally connected to the underworld.

[Due to the influence of the underworld's aura, the host's skill of summoning water elements has transformed into - summoning the underworld night wanderer]

[Due to the influence of the underworld, the host's skill of summoning the Sky Knight has transformed into summoning the Black and White Impermanence]

[Due to the influence of the underworld, the host's skill, Flame Armor, has transformed into Rashomon Protection Field]

.....

Various creatures from the underworld were summoned to carry out dimensionality reduction attacks.

Qin Yu also kept changing jobs, and his status in the underworld became higher and higher.

Several years later, a large number of monsters invaded the forbidden area of ​​the abyss.

Above the clouds.

Qin Yu, dressed in black, flipped his hand and took out the Book of Life and Death.

"If you dare to disturb this Lord Yan, I will erase ten thousand years of your lifespan."
