Heavenly Dao Engine - Chapter 15 - 00: Monster

“Oh Lord Lunareio, you are the only one who can save our world.”...My name is Rikuya Takatsuki, and I didn’t ask to be summoned to some fantasy world with my classmates. But there I was, expected to be a hero and protect the Kingdom from Realm Eaters, dimensional monsters chewing through reality.Apparently, all the races summoned forth heroes of legend, which was sort of a shocker to me since it wasn’t the cliché “slay the demon king” trope.Sounds cool, right? Wrong. While everyone else got flashy powers and legendary classes, I was slapped with the FFF Auto Hero class—no skills, no perks, and no respect.The kingdom handed me some pocket change and politely told me to scram.Fine by me. I was all set on enjoying the easy life in this new world anyways, when out of nowhere a bunch of cultists kidnapped me, claiming I’m their prophesied god or whatever.They gave me a mansion, unlimited snacks, and zero responsibilities, so of course, I played along.But then my so-called useless class kicked in. Turns out Auto Hero means my body hijacks itself whenever there’s danger, turning me into some kind of unstoppable killing machine. Efficient? Sure. Ethical? Not so much. Now everyone thinks I’m this terrifying cult leader who takes down monsters, corrupt kings, and anyone dumb enough to stand in my way.While my classmates enjoy their shiny hero lives, I’m here in the shadows, leading a cult, toppling kingdoms, and pretending I have some grand plan. The truth? I’m just winging it.I mean... what’s the worst that could happen?

Life is often full of curveballs. It likes to keep you on your toes.But what can a regular guy do when he gets booted to a world full of gods, dragons, devils, angels, yokai vampires and everything in between with only the clothes on his back and a reality-bending gacha behind him?His best apparently.

In humanity’s final war against the Demon Lord, the strongest heroes fell—not by the enemy’s hand, but by their own, twisted into madness by a cruel illusion. Betrayal. Bloodshed. Despair… and then, silence.Only one person remained: Riley—the weakest warrior of them all. Powerless. Ignored. Forgotten.But he saw through the Demon Lord’s deception. The tyrant was on the brink of death—so weak even a fly could’ve finished him off.And Riley did just that, drawing every last ounce of strength to bite off the demon’s head.Victory? Not quite. A final, desperate strike from the Demon Lord pierced him from behind, killing him instantly.But fate wasn’t done with him yet.Riley awoke ten years in the past—when the online game [Apocalypse] was launched. Before demons descended. Before monsters overran the world.And this time, he wasn’t starting from nothing. He had a decade of experience—and a second chance.Even more shocking, he didn’t awaken his old D-rank Strength Boost talent. This time, he received something far more terrifying: an SSS-Rank Gluttony talent!He could now devour anything—monsters, items, talents, even traits—and gain their power.Ding![You have devoured: Iron Fang Wolf][Acquired: +4 Strength, +2 Agility, Skill: Bite (F-rank)][You have devoured: Goblin ShamanAcquired: +8 Intelligence, Skill: Mana Bolt (E-rank), Talent: Minor Spellcasting Efficiency][You have devoured: Flaming Salamander Drake][Acquired: +22 Endurance, Trait: Dragon’s Resilience, Skill: Flame Breath (C-rank)]Now, there is no demon, no god, no monster who will stand in his way. He will devour everything—and save the world.But the power of Gluttony was a double edged sword. If he wasn’t careful… he could be the one getting consumed.

Thirty thousand years ago, the Heaven Fighting Race who called themselves “Gods” invaded the Spirit Realm. Hundreds of races rose up in resistance, but ultimately suffered a crushing defeat. The Human Race was the first to concede, and the rest of the Hundred Races soon followed in succession.
