Get Out of the Way! I'm Saving the World!

Originally titled "Waiting for You When the Plum Blossoms Bloom." Her true form is invincible, but an accident turns her into a baby. Fortunately, she gets an extremely old mother, and begins a new immortal life in the Upper Realm. Unfortunately, even the Heavenly Emperor is no match for the wicked. He tricks her into reincarnating in the Lower Realm, where she begins her journey to save the world.

The journey to the Lower Realm is rather bumpy. When she finally returns home, she discovers that war has broken out in the Upper Realm. Her mission to save the world continues, but this time she faces a conspiracy tailor-made for her.

Big sis, it's time you learned your true identity. This is your world!

The whole story has undergone major revisions, and the plot has been rearranged. I hope this gives you a better reading experience.
