A sudden rain of blood overturned the original order of the world.
The moment the bloody rain fell, the old era came to an end.
After the bloody rain stopped, weird and terrifying events followed.
There was a sudden power outage across the world, the network was completely interrupted, mobile phones, cars, thermal weapons... All products that relied on modern technology were ineffective and turned into a pile of useless scrap metal.
Immediately afterwards, the aliens descended boldly from the darkness.
Goblins, kobolds, minotaurs, vampires, ghouls... Countless ferocious monsters that exist only in legends are rampant across the land. The city has become a purgatory on earth, and the world has turned into a bloody slaughterhouse. Human beings were retreating steadily under the claws of monsters, and in an instant they were in dire straits and on the verge of extinction.
Just as despair spreads, mysterious altars suddenly appear all over the world.
Humans can sacrifice items in exchange for materials, abilities, weapons and equipment to strengthen themselves and struggle to survive.
In this collapsed new world, there is no order, no mercy, only the law of the jungle.
Survival has become the only rule.
