Gender-Swapped Cultivation: In the Name of the Yang-Devouring Demoness

[Male-to-female transformation + absorbing yang energy + no male lead + no System + definitely not AI-generated + independent cultivator] Liu Han wakes up to discover that he has become a newly fertilized embryo. After developing in the womb for ten months, he is born safely. To Liu Han's dismay, it seems he has gone from being a man to a baby girl. Before Liu Han can even come to terms with it, he is given his new name: Liu Hanyan! The scene shifts to six years later. Liu Hanyan is now six years old. During this time, Liu Hanyan has learned that she transmigrated to a world of immortal cultivation. The city where she lives, Jiuyang City, is controlled by the powerful Jiuyang Sect. Her parents are ordinary people, a couple of herb gatherers in Jiuyang City. They have to search for and collect medicinal herbs in the Jiuyang Mountains outside the city, then sell them to the city's apothecaries for a living. Today is Liu Hanyan's first time accompanying her parents to gather herbs, so she can learn the skills she'll need to survive in the future. But accidents always come without warning. They suddenly encounter a demonic beast. Her parents die in its jaws while protecting Liu Hanyan, and she falls off a cliff. Below the cliff, Liu Hanyan's tiny body hangs from a branch, blood dripping steadily from her wounds. Beneath her is a withered little vine. After absorbing Liu Hanyan's blood, it recognizes her as its master! This vine is an ancient demonic plant called the Sun-Devouring Vine. Its stimulus awakens the Sun-Devouring Yin Body lying dormant within Liu Hanyan, along with the cultivation method that comes with it: the Sun-Devouring Yin Scripture. From that day on, the cultivation world welcomes a demonic woman who specializes in absorbing yang energy!
