My Ex Started Cultivating Immortality

My name is Li An, and I'm freaking out right now.

Just as I was about to start a new relationship, the voice of my ex, who had been dead for three years, suddenly appeared in my mind.

It turns out she transmigrated to a cultivation world, and that world is about to invade Earth.

As the only person on Blue Star she can contact, I have to step up and fight for humanity's survival.

Blue Star authorities: “Student Li An, given Ms. Shen Zhiyi's importance to humanity's resistance against the cultivation civilization, we hope you'll keep yourself in check and not let her lose her ties to humanity.”

Li An: “Don't lose sight of the bigger picture! I can cultivate too, you know? And she's just my ex!”

Shen Zhiyi: “Could it be that the cultivation civilizations that like invading other worlds are all demonic factions? Because I happen to be a female demon lord.”
