(Sword Art Online + Demon Slayer fanfiction)

As a transmigrator without any cheat codes, Tomioka Akemi was a little panicked when he found the breathing technique notes left by his ancestors. But when he thought that it was already 2022, how could there still be demons? He calmed down, until he heard about the SAO closed beta test...

(Single female lead, Asuna, tentative storyline is Sword Art Online ---- Fairy Dance ---- Demon Slayer)

When Shen Lang opened his eyes, he found himself to be cannon fodder at the very bottom of the dark world.

The greenskins roar, the ratmen dig burrows, the evil gods whisper, and humans are nothing more than trembling ants in the cracks.

But his eyes can see different things.

[Automatic attack mode activated!]

[Analysis: The soil beneath our feet contains 37% iron, making it suitable for smelting!]

[Warning: Chaos storm will arrive in 3 hours. Wall erosion resistance: 0%!]

While others prayed in fear, Shen Lang lit the first furnace amidst the ruins.

When cultists sacrificed flesh and blood to summon demons, he pierced their throats with a tempered steel spear.

When the war machine of the Greenskinned warlords rolled over the village, he ordered the villagers to teach them what it meant to "line up and shoot" with smoothbore cannons and barbed wire.

As the Tomb King's undead army engulfed the land, he set up a red-hot heavy Gatling gun, its ammunition roaring: "Times have changed!"

From a stone axe to a torrent of steel; from an earthen wall to an immortal fortress.

Shen Lang said, "I don't know magic, nor do I believe in gods. My faith is the sight of a flintlock musket, the piston of a steam engine, and the steel and fire that cover the battlefield!"

This is the fortieth millennium.

The gods are silent, the demons roar. The human empire slowly sinks into decay amidst endless war and corruption.

Ang Lee, one of the millions of slave laborers in the Nest City, discovered a glimmer of light from ancient Terra in the eternal darkness—an ancient movement called the Way of Peace, and an unfinished prophecy: "The Blue Heaven is dead, the Yellow Heaven shall rise."

He never imagined that this glimmer of light would eventually ignite a prairie fire.

Talismanic water and alchemy countered Nurgle's benevolence, a tightly organized force shattered Tzeentch's conspiracy, and the beliefs of mortals surged in the Warp, giving birth to an unprecedented being—the Yellow God who governs "order and revolution."

However, Ang Lee gradually discovered that the greatest enemy was neither the Empire's expeditionary force nor the ever-watchful Chaos God.

Rather, it is a reflection of his own ideal—that which is trying to devour him, dragging everything he pursues into a cold, absolute abyss of order…the embodiment of divinity.

When the bells of destiny toll, he will embark on a long expedition to confront the painful and immense will atop the golden throne.

This is not a war to kill gods.

This is proof of humanity, an ultimate defense of free will, a testament to this despairing galaxy...

The final expedition to rediscover "humanity".
