She gazed at the screaming, wielding weapons of goblins, orcs, dark elves, barbarians, and imps... and pleaded, "Warriors, why have you come to this?" "Waaaaaaaaaa!!" "The Blue Heaven is dead, the Yellow Heaven reigns!" "The world belongs to the Wings of the Abyss!" "The Abyss nobility reigns!" "Damn it, who touched my ass?" Then, a gust of black wings covered the sky. Levis, the Wings of the Abyss, the last true dragon lord, protector of the abyss, driver of the cancer of the world, the sinful black dragon, said helplessly, "When did I ever say I would conquer the world?"

Xia Moan, a hardcore base-building and resource management game enthusiast, is summoned by the desperate half-demon Talia Ronoway. He journeys to another world and is unexpectedly possessed by an ancient cursed armor. He builds the most powerful Demon King's city from scratch in the harsh underground demonic realm! What? Building a dungeon is difficult? Here's the "Alien Underground Colony Construction System"! The most advanced technology is indistinguishable from magic, and the most rational science will incorporate magic into its systems! The stage of elven lords, dwarven princes, and demihumans is gradually coming to an end. The struggle of the four kingdoms, the war of kings, the era of humanity has just begun!

The wasteland is the gold mine and burial ground of the Adventurer's League, and the back garden of the demon rulers! Magic stone warriors,...

The seals of the nine ancestral planets have been broken, and evil is devouring all worlds! A black sun hangs high in the galaxy, and countless worlds are reduced to purgatory. And Blue Planet—the last untouched pure land—is home to the Three Sovereigns and Five Emperors, Pangu, the celestial god, the founders of the three religions, and the Twelve Gods of Olympus. "The blood of the ancient gods flows in your veins!" Lin Xuan's soul escaped the seal of the primordial planet and entered the great realm of the heavens.

Chu Sheng was a little silent about this opening.
