If I take in disciples, I grow stronger; every one of my disciples astounds all heaven and worlds.

A catastrophic nuclear explosion swept across the globe in an instant, triggering sweeping destructive shocks that flattened modern cities, shattered global ecological systems, and plunged the entire world into irreversible ruin. Ten long years have passed since the apocalyptic disaster. Vast, desolate wastelands now extend boundlessly in all directions, blanketed by pervasive, lingering radiation that hangs thick in the air. The once vibrant blue planet has turned gray and barren. All prosperous civilizations, bustling towns, and fertile farmlands have vanished without a trace. Humankind, once the dominant species on Earth, has been utterly reduced to weak insects, forced to struggle painfully for survival in the narrow, harsh cracks of this broken and dying world. Beneath the endless floating radioactive dust and gloomy eternal gray sky, every remaining survivor clings to their fragile life by any desperate means possible. Resources of every kind have become extremely scarce in the wasteland. There is no stable food supply, no clean drinking water, and no safe shelter to escape the harsh environment. Survivors wander aimlessly through piles of collapsed rubble, scrambling fiercely with one another for fragmented abandoned supplies left behind from the old world. To stave off deadly starvation, most people have no choice but to hunt and feed on mutated insects and contaminated low-level creatures that adapt to the radioactive land. Dangers haunt every corner of the wasteland, bringing constant death and despair. Violent raging sandstorms break out frequently, sweeping across the barren land and burying makeshift camps and wandering survivors in the blink of an eye. Diffused lethal radiation invades the human body relentlessly all year round, causing stubborn skin lesions, festering illnesses, and irreversible physical damage. Meanwhile, ferocious mutated beasts, twisted and strengthened by long-term radiation erosion, roam freely across the wilderness. They hunt living creatures endlessly, claiming countless human lives every day, making survival an endless torment for humanity. Trapped in this cruel and hopeless doomsday world is Chen Li, a former agronomy graduate student who once dedicated his youth to researching high-yield crops and modern agricultural planting in the peaceful era. He once dreamed of feeding more people with professional knowledge, yet the sudden apocalypse crushed all his aspirations. After ten years of tough survival, he finally fell into a desperate predicament. Severely injured in a sudden mutated beast attack, he is now trapped alone in a dilapidated abandoned bomb shelter, completely isolated from all survivor teams and external help. His left leg suffers from severe radiation infection, with the wound continuously festering and suppurating. The piercing, constant pain drains his strength and erodes his will to survive. To make his situation even more critical, a dense tide of greedy radioactive rats has surrounded the shelter entrance. These radiation-corrupted creatures wait patiently for his vitality to fade, ready to devour him at any moment. With no food, no medicine, and no way to escape, Chen Li lies weakly on the cold ground, hovering on the verge of death, ready to succumb to the brutal wasteland at any second. At his most desperate moment, a ray of miracle breaks through the darkness. The powerful Doomsday Sign-in System silently awakens and binds exclusively to him, bringing a glimmer of infinite hope to his doomed life. The system grants him generous rewards through daily sign-ins, including all kinds of rare and precious survival supplies such as sterile food, purified water, hemostatic medicine and anti-radiation agents, thoroughly resolving his urgent life crisis. Most precious of all, he obtains a batch of exclusive god-level wheat seeds that transcend ordinary mortal varieties. Along with the divine seeds, the system unlocks a unique portable spatial farm for Chen Li. Independent of the polluted outside world, this magical farm boasts powerful purification and planting capabilities. It can thoroughly purify radiation-polluted barren soil, turning toxic, lifeless land into fertile, nutrient-rich planting fields in a short time. It perfectly nurtures peerless divine crops with extraordinary vitality. These miraculous crops not only produce abundant, endless food reserves but also contain subtle pure energy that resists radiation, repairs bodily damage, and strengthens physical fitness. From a dying survivor on the brink of extinction, Chen Li gains the supreme capital to take root and thrive in the wasteland, embarking on a legendary doomsday survival journey dominated by divine planting.
