In an underground abyss where sunlight never reaches, gold is the beat of your heart.
Li Wei, a living heart stripped of his human body, uses each beat as fuel to craft stone golems, refine blood gold, build a base, and open up mining veins. From hunted prey, he rises step by step to become the creator of the abyss.
But every evolution comes at a price: his tentacles are torn off for good, his war chariot is dismantled piece by piece, and his old heart becomes a key. The countdown of his heartbeat echoes in his ears forever.
When the heartbeat of the seventh level rings out, Li Wei must decide:
Will he keep using gold to prolong his life, or become the final beating heart himself?
