Devouring Evolution from Metal

It turns into metal at the beginning, and its evolution depends entirely on swallowing. "Boom! You swallowed a giant steel city and gained **evolution points!" "Boom! You swallowed an artifact and gained 1,000,000 evolution points!" World-Destroying Dragon: "Damn it, why doesn't this dragon's flame work on it!" God-level magician: "Impossible, my magic is completely immune to it!" Qin Tian transformed into a giant metal city, and the gods retreated! This novel and its characters are purely fictitious.
