The Resurgence of the Fallen Gods: Humanity as Blood Food

The era of Dharma's end comes to a close, and the spiritual energy of heaven and earth suddenly revives. But what returns is not a heavenly gift; the ancient gods have all fallen into evil, transforming into man-eating malevolent deities. Strange beasts break through the soil, ghosts and monsters run rampant, countless dimensional barriers shatter, and otherworldly demons swarm into the human world, reducing humanity to fresh blood food for all creatures. The surviving human powerhouses hastily establish cultivation academies, teaching techniques to resist the enemy, and people worldwide struggle against the catastrophe. Yet the shadow of death looms over the globe. To survive, the powerful and elite plan to capture the lower classes and sacrifice them to the evil gods in exchange for a respite. Under immense oppression, the Chinese underclass rises in rebellion, overthrowing the corrupt upper class and using the blood and flesh of the elites to temporarily delay the disaster. But the brief peace is an illusion. Overseas territories fall one after another, mutated sea monsters rampage, and otherworldly evil gods continue to expand. To preserve the elites, the United Nations launches a cruel interstellar migration plan, directly abandoning the vast majority of the lower classes, who become livestock blood food. Just as humanity is on the brink of total extinction, an alien protagonist accidentally crashes onto Earth and becomes the only glimmer of hope in despair. He contacts his distant home planet, single-handedly holds off the main force of the evil gods, and unites Earth's remaining forces with interstellar reinforcements to launch humanity's desperate counterattack. — Description from novelcodex.org
