MTL - Rebirth in a Perfect Era - Chapter 1266 setup well

She is the twenty-fourth century’s strongest immortal cultivator, but transferred into a world of magic where demons roamed rampant; a punching bag tyrannized and ostracized by her clan on one side while the scum of a man that is her fiancé humiliated, trampled her on the other side…

After escaping his own death, the Deity of Void woke up in a human slave's body. He became utterly frustrated after this failed attempt. However, he was glad enough to have escaped. His only problem now... is living in this human body, which has limited time. That's something a deity like him won't be able to bear.He's a deity in a human's body with one goal; to achieve an eternal life. And he would absolutely do anything to achieve it.

The main character is reborn as a character from a game he played in his previous life. This character falls into ruin along with the villainess, spending the last of their years together. A man named Kururi Helan.
