King of the Undercity

A miner, Adrian, buys a diamond ring for his fiancée but is humiliated by her and Jason, heir of the Upper City, then thrown into a waste pit. In an abandoned bio-zone, he inherits the First King’s power and becomes a bio-enhanced armored warrior. Rising through underground pit fights, he marches back to the Upper City, freezes the Golden Crown’s assets, destroys the Elder Core, defeats Jason, and founds Free City—only to face the looming threat of the Verdant Empire.
