The Secret of Becoming an Immortal

I actually transmigrated into the pet of the strongest sect's Saintess?!

I eat, live, and sleep with the Saintess every day, yet still find myself facing a life-or-death crisis? Fine, fine. To stay alive, and to keep sleeping beside the Saintess, I have to survive!!! Whether it's cultivating immortality or tempering my body, watch how the protagonist goes from a little kitten at the start to the only immortal in the world!

No System, some romance, a light-hearted power fantasy with a bit of thoughtful cultivation, no recycled tropes, and absolutely no padding. I'll keep writing until the whole book is finished. Thanks for reading!
