Beneath the Vast Sky

65 million years ago, the insectoid race came to Earth from distant outer space to plunder heavy metals. Before long, the divine race arrived for the same purpose, and war between the two species was on the verge of breaking out. They exhausted all their high-tech weapons and warships against each other, leaving them stranded on Earth. A meteor crashed into the planet, making its surface uninhabitable, and the survivors were forced underground to live.

With resources scarce, knowledge forgotten, and technological chains broken, everything returned to the primitive age. The three races began fighting to attain a higher civilization.

Four underachievers accidentally ventured deep into the world beneath the Earth's surface and began using modern human civilization to restart underground civilization. There was no poetry or romance here, only schemes, power, and slaughter...

Martial arts against ancient boxing techniques, firearms against cold weapons...
