The Supernatural era descended, the rules changed, mystery arrived, and the world altered. Countless ruins of civilization emerged, and an abundance of Heavenly Materials and Earthly Treasures lay at everyone’s fingertips. Radical faction, “This is the best of times, entering a new world, excavating relics, mass evolution!” Conservative, “This is the worst of times, with countless monsters outside, once you leave the Safe Zone, extinction awaits humanity!” … Meanwhile, at a remote ruin, Lu Yuan successfully discovered new treasures and sought after the mysterious wealth, desperately trying to contact his fellow Earthlings. “Found a communicator, can it get through?” “Hey, humans—I’m almost becoming a god, and you’re still hiding in the Safe Zone?”

All her life, Eleanora did everything to make him love her but in the end, what she got from him was her execution for a sin that she never did.

Before dying, Eleanora coldly stared at his bloody red eyes as he lifted up the sword to execute her…

“I will never forgive you for killing me and my child.”

For the first time in her life, She saw his anxious gaze.

But it was too late as the sword in his hands had already landed on her neck, separating it from her body.

Eleanora finally thought everything was over but then she opened her eyes again, to find herself back in 12 years in the past when all the misfortune was yet to happen.

She was firm to change her tragic ending this time but it was not only her who changed…

“Even if you hate me, you can only be mine in your every life… My Empress.”.....
