In a time of dynastic chaos, monsters roamed freely, and the people suffered immensely.

Su Yu lost his parents at a young age and studied hard for twelve years to become a doctor. He wanted to live up to the expectations of his childhood sweetheart who had taken good care of him.

Unexpectedly, Su Yu's kindness in saving people was repaid with enmity by the old man, who attracted demons and brought disaster upon Qingmei!

"Human suffering! Transcendence on the other shore! With my sword, I will send you to heaven and to the other shore!"

In the bustling tavern, a bard sang the legend of a dragon-slaying hero by the fire, while several adventurers gathered together to play monster cards. Mali finished the remaining capsule coffee in his thermos and said to the half-elf girl beside him, "Let's go, it's time to go," the kind waitress warned. "But there's a group of vicious snake-men bandits lurking on the road ahead. Why don't you wait a little longer? The Baron is already recruiting mercenaries." "No problem, we'll drive."

When death approached, Ding Xie glimpsed a sliver of truth—some were monsters, lurking among the people, devouring flesh and blood; some were demons, mingling in the marketplace, slaughtering families; some were gods, residing high in temples, killing countless. He gently patted the coffin lid, flicked the incense of bliss, and offered sacrifices to countless people. Here, he used his quick-draw gun technique, running rampant without restraint. Here, he used paper-cutting to become a flying immortal, and shadow puppets to become gods. Here, he used his waist drum to set up the Imprisoning Heaven Array, and used the stove fire to save all people. And everything started from that 'legacy'.

Under the extreme test of a post-apocalyptic environment, the survival of human civilization and the choices of humanity—when survival instincts collide with moral bottom lines, when individual strength intertwines with collective destiny, is the apocalypse the end of civilization or the beginning of reconstruction? This novel will explore the survival and transformation of civilization in extreme environments through the intertwining of genetic technology, the struggle for survival, and the struggle of humanity.

II. Worldview Setting

2.1 Doomsday Triggers: Triple Screening

Genetic Virus Outbreak: In 2077, a genetically modified virus called "Crimson Dawn" escapes control, capable of rewriting the genes of almost all organisms, causing terrifying mutations in all life forms worldwide. This virus can infect all life on Earth, including humans, becoming the first screening factor in the collapse of civilization.

A red fog descends: After the virus outbreak, a mysterious red fog appeared in the sky. This fog is actually a "gene filter" from an alien civilization, capable of activating hidden potential in biological gene chains and accelerating biological evolution. However, it also leads to instability in biological genes, causing uncontrolled mutations.

Remnants of nuclear winter: In an effort to control the spread of genetic viruses, governments worldwide launched "Project Ice," using biotechnology-based "freezing bombs" to turn low-lying areas of the world into ice ages, triggering a global nuclear winter. Residual radiation caused some areas to become "dead zones," but it also gave rise to the rare resource "radioactive nuclei."

In the year 1838 of the First Emperor's calendar, the Tianyuan War ended. A man, having just traveled through time and space and been forced to fight for six years, cast aside his great sword and, with a broken heart and a sense of loss, staggered away from the devastated battlefield, wanting to see this strange and mysterious world. Our story begins two years after he regained his freedom. However, he discovered that things were not so simple.

So delicious!

No harem, light-hearted and humorous style.

Snow Kirin, the divine beast under the seat of Hades, was seriously injured while fighting alongside the Lord of the Underworld to deal with the catastrophe in heaven. He lost his Sky Soul Pearl and had only the Earth Soul Pearl left in his body, becoming a forgetful and evil beast.

In order to help his partners find the Sky Soul Pearl, Ming Zun personally arranged for Xue Qi to reincarnate into the human world and wait for an opportunity.

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!"
