Chương 10: The Flame That Burns the World

[Successfully Integrated] [Name: Lightning Devil Slayer Magic] Level: 01 / 100 Type: Passive Rarity: Super Rare Lightning Devil Slayer Magic is a form of Slayer Magic that allows its user to wield a specific element for the explicit purpose of exterminating demons. Unlike standard elemental magic, Slayer Magic is fundamentally predatory in nature.

This magic allows its user to create, generate, and manipulate lightning, but the lightning produced by Devil Slayer Magic is fundamentally different from ordinary electricity. It carries demonic annihilation properties, making it exceptionally lethal to demons and corrupted beings. The user is capable of consuming lightning —natural or magical—to replenish stamina and magical power, while also gaining immunity to lightning-based attacks.

Among the three Slayer standards—Dragon, God, and Devil— Devil Slayer Magic possesses the highest electrocution and extermination capability, making it especially effective against demonic entities. However— This spell is known to be extremely unstable. If learned too quickly or used recklessly, Devil Slayer Magic can cause demonization. This manifests as black markings spreading across the user's body, changes in eye color, and progressive corruption of the soul.

It has been noted that the souls of demon hunters gradually become contaminated, which may lead to loss of sanity, emotional instability, and irrational decision-making. At mastery, the user can manifest these markings voluntarily, gaining limited resistance to curses and demonic corruption.

Lightning Devil Slayer Magic grants the ability to: Paralyze at an absolute level Vaporize targets Burn both flesh and soul Extract information about demons through observation Generate massive storm systems capable of covering entire skies [Devil Force — Locked] [Requirement: Level 50]"… That's insane." When I raised my left hand, a tribal tattoo shaped like lightning and thunder revealed itself along my arm. Purple electricity crackled around my wrist, alive and restless. This book is hosted on another platform.

Read the official version and support the author's work. This wasn't ordinary lightning. This was execution. Still, a concern gnawed at me.

"System… can this spell turn me into a demon?" Honestly, that was the one outcome I absolutely did not want. [Negative.] [Due to System Regulation, the Host will not permanently demonize.] [Upon unlocking Devil Force, the Host may temporarily assume a demonic state to access enhanced abilities.]"I see."

"…You really are amazing, System." For a brief moment— I felt something like pride emanate from the System. [Naturally.]"…Wow. That was pride." Okay. Enough distractions. I turned my gaze toward the massive door ahead.

"Time to enter the boss chamber." I stepped forward and pushed the door open. [You have entered the Chief's Room.] [Good luck, Host.]"Thanks." The chamber illuminated as I stepped inside. What greeted me was a vast throne room, carved entirely from obsidian stone and rivers of molten lava. Heat distorted the air itself, making every breath heavy. At the center of the chamber— A massive throne of stone and flame. And seated upon it— A towering being, well over two meters tall.

His body was composed of living fire, molten rock constantly shifting beneath his form. The heat radiating from him was overwhelming, pressing down like a physical force. Resting against his shoulder was a colossal medieval sword, its blade forged from cooled, condensed lava—dense, brutal, and unmistakably lethal. He looked like something straight out of a Thor movie. Flanking him were four massive demons. Two on each side.

They were enormous—bulky red-skinned ogres with grotesque builds, purple maws, long tongues lolling from their mouths, and thick curling horns. … They looked disturbingly similar to the red demons from Nanatsu no Taizai.

"So the dungeon isn't picky," I muttered."Anything that counts as demonic gets thrown in." Time for intel." Eye of God."..... [Name: Surtur] [Lineage: Demon] [Title: Flame Demon] [Level: 24] HP: 24, 000 / 24, 000 MP: 15, 000 / 15, 000 STR: 1, 200 VIT: 2, 400 INT: 500 DEX: 800 LUCK: 100 [Status Effect (Host): Extreme Hostility — "Hate for hacking this domain"].....

"…Even the name matches." A High-Class demon. Massive vitality. Insane endurance. And four Middle-Class guards backing him up. Not ideal. But not impossible. [New Quest Available] Oh? [Quest: Demon Hunter 2. 0] Objective: Kill the Demon Surtur Rewards: • 100, 000 Gold • 500 EXP • Skill: Hellblazer"…Now that is a reward worth fighting for."

"System," I added, "you really need better naming sense for quests." [That responsibility lies with the Goddesses.] I felt a bead of sweat roll down my back...... A Distant Existential Plane On a plane far removed from Gilgamesh and the DxD world, three goddesses lounged on a massive sofa, snacks piled high, watching Gilgamesh's progress like a live broadcast. They laughed loudly, thoroughly entertained—millennia of existence made novelty rare. Until the System blamed them.

"Hey! That's not our fault!" one goddess protested indignantly."That's the author being lazy!" The other two nodded in agreement...... An Even More Distant Plane Beyond gods, worlds, and fiction itself— The Author sat in his own universe, sovereign of a personal cosmos. He paused mid-writing.

"…Fair." Then—"Come wash up now!"

"Yes, mom!" the author shouted, abandoning godhood instantly. Turns out— There's always someone above you...... Back in the dungeon— Surtur slowly rose from his throne. The lava beneath the floor bubbled violently. Flames surged higher. The temperature skyrocketed. The four demons cracked their necks and advanced. I smiled calmly.

"Alright."

"Let's see whose fire burns brighter."
