A World of Character Building: Choose the Fated Girl from the Start

On this world's Blue Star, immortals and gods rule over countless worlds.

When people turn eighteen, they can descend to the lower realm and choose someone to form a contract with, making that person their Chosen One.

Time passes a hundred times faster in the lower realm than in the upper realm.

Raising one's Chosen One to grow stronger, then drawing strength from them in return, is the path of cultivation on this Blue Star.

While the scions of the gods all set their sights on candidates of noble birth, endowed with all sorts of special royal physiques,

Bai Chen approaches a girl.

"You say you were a young genius, but your power inexplicably regressed three years ago, and now you're only at the third level of Body Tempering?"

"Good. You're the one."
