Book of Contracts: Starting with a Contract with a Fallen Female Swordswoman

[Contract with Spirit Master] + [Evolution] + [Decisive Strike] + [Survival Strategist]

After traversing the cultivation world for ten years, Zhang Daobai, on the verge of leaving his sect, finally activated his golden finger, the Book of Contracts, and embarked on the path of spirit control.

What is a spirit master? Any living being with intelligence, or even a non-living being, can be contracted to become a spirit master.

Zhang Daobai:

Humans are the most intelligent of all beings, and should also be able to make contracts!

Sword spirits are spirits too! Weapon spirits are spirits too!

What?! The spirit of this small world possesses sentience! Hehe!
