Awakening the Chaos Body Through Transformation: I Want to Be a Sword Immortal

Gender swap + two powerful leads + genius

After his parents died, his grandfather changed his name to "He Buke," meaning he should fear nothing and meet every challenge head-on.

Sadly, he still ended up alone, unable to fit in with his classmates.

After transmigrating, she was still called "He Buke," but only because she'd been born unconscious, like a stillborn child, and nothing seemed possible for her.

Now, though, she was determined to be brave for once, setting out on the treacherous and perilous path of immortal cultivation to stand at the pinnacle of the world!

(The female lead is pretty weak at first, but later she'll lay waste to heaven and earth.)
