Useless Disciple? I Push Open the Gates of Hell!

Transmigrate into the useless "Gatekeeper" who was scared to death by an F-rank monster?

Lu Ren says that the ability everyone despises as useless

is an endless treasure in my hands!

Devour everything with my left hand, and open a hundred levels of demon prison with my right!

Devour an F-rank Corrupt Sludge Spider = attributes slightly increased, Shadow Servant unlocked

Devour a C-rank Three-Headed Demon Hound = attributes soar, Demon Hound Shadow Army unlocked

Devour an SSS-rank Calamity Evil God = ???, World-Destroying Divine Shadows unlocked!

When a city-destroying demonic tide descends, S-rank heroes fight desperately in a pool of blood, and the whole city despairs.

Lu Ren quietly shuts the door instead. "One hour outside is ten hours inside. I'll clear a hundred levels first to calm my nerves."

The strongest Flame Emperor: "My heavenly flames, which burn everything to ashes, couldn't even hurt that demon dragon. He... he ate it in one bite?"

The Federation Goddess: "Student Lu Ren, that army in your shadow seems even stronger than our Federation army..."

When the Lord of the Abyss descends to judge all of humanity,

behind Lu Ren, billions of divine and demonic shadows open their blood-red eyes.

"Excellent ingredients. My shadow army happens to need a gatekeeper."
