The Mech Emperor, Volume 5. The Mech Emperor, #5

In a prime material plane dominated by sorcerers, powerful warlocks wield terrifying abilities to overturn seas and move mountains. They capture gods, enslave demons, and colonize one realm after another, reaching an unprecedented peak of prosperity and establishing a series of glorious and mighty Sorcerer Dynasties. After the fall of the Eighth Sorcerer Dynasty, formidable gods, sinister demons, cunning devils, and forbidden monsters-one fearsome race after another-begin to stir with unrest.
Yang Feng, transported to this prime material plane with an advanced intelligent robot from the Xi Clan, embarks on the path of a warlock as an alchemist. Pursuing the mysteries of eternal life, he forges his own legend in a world teetering on the brink of chaos.
