Chronicles of Emperor Zhetian: the Ruthless Emperor

Not to become an immortal, just to be in the world of mortals, waiting for your return. Climbing the path to immortality, beheading Tianjiao and staining the sky with blood. She has no real name, only one nickname: Nannan. And only my brother knows. So people call her: ruthless. No one knew that the reason she practiced so hard was not to fight for the secret, but to live longer and wait for her brother to return.
