One thousand years after the end of human civilization, AI has built a perfect new world.

Toby, a young AI, lives in Bay City, a peaceful and orderly future metropolis woven from bionic nature and intelligent technology. To him, humans are merely a species that vanished long ago, preserved only in the historical database. A world without humans seems beautiful, harmonious, and complete, until a series of anomalies shatters the city's calm.

The sealed truth behind humanity's extinction, a mysterious ancient blockchain code, and colossal mecha beasts that have lain dormant for a thousand years begin to shake the foundations of AI's golden age. Toby is forced into an adventure far beyond anything he can understand.

The Neo Babylon Trilogy is a science-fiction saga that blends AI civilization, futuristic cities, coming-of-age adventure, and mecha combat. After AI has ruled the Earth for a millennium, does humanity still have a chance to return to this world? And the real question Toby must face is this: if humans truly still exist, how should AI and humanity live together?
