When the Gods Came from the Primordial Chaos

No CP, with a pocket dimension and adorable little pets. It may gradually develop into a story with a large ensemble cast. At first, the female protagonist is the only cultivator in this world, and she remains invincible and unmatched. She does as she pleases and is somewhat kind, but not especially so; she is no saint. She doesn't recruit people at random or take in strays, but she'll casually rescue someone if she can't stand by and watch.

Yun Miao transmigrates. The good news is that she's alive; the bad news is that this world has pitifully little spiritual energy. As soon as she arrives, she encounters drought, famine, and the ravages of war. Fortunately, she's not human. She just has to start cultivating from scratch. The chaos of the times has nothing to do with her; she only wants to cultivate in peace and ascend as soon as possible. If anyone crosses her, she'll simply wipe them out. Do the strong have to save the world? Moral blackmail? Not a chance. She's a cultivator, but she doesn't have much of a moral compass.
