Infinite Returns for My Domain: I Go on a Rampage After Contracting the Empress

In the Age of Lords, I bound myself to the Contract Return System from the start.

Contractors share their talents, and rewards for killing enemies are returned at a multiplier!

Well, in that case, why not contract a few future female Emperors from the start?

[Contracted female Emperor reaches mastery in Star Pole Fist, returned a hundredfold as perfect Star Pole Fist Intent]

[Contracted female Emperor breaks through in movement techniques, returned a thousandfold as speed increased ten thousandfold]

[Contracted female Emperor obtains a Flame Spirit Kun Beast, returned ten thousandfold as the ancient divine beast Phoenix!]

[Contracted female Emperor obtains a top-grade Tai'a Sword, returned ten thousandfold as the divine weapon Immortal-Slaying Sword!]

A few years later, the female Emperor Lords have all gone mad!

Female Emperor: Why do I always feel like a shadow is looming over me!!!
