Reincarnated in another world, my tamed beast is a stunning empress.

Reborn into a world of beast taming, Han Lin awakens a life-refining system, becoming stronger by refining the blood and spiritual power of demonic beasts. Although this is a world of beast taming, and the summoned spirit beasts aren't good, resulting in slow power increases, Han Lin doesn't mind. ...Why is it a person? Is this a spirit beast? ...Ling Siru, Empress of the Human Race on the Devouring Heaven Continent. She was killed with a single palm strike while fighting for the Reincarnation Treasure in the Ancient Secret Realm. Fortunately, her soul attached itself to the Reincarnation Treasure, allowing her to reincarnate with it. This is a world of beast taming, so what is my spirit beast? What? You say I'm a spirit beast? ...It's alright, I have the Reincarnation Treasure. The Reincarnation Treasure recognizes its master? So I'm a gift you gave it?
