- Description from Novelupdates

Regret filled Valyr as he witnessed Earth before him crumble into nothingness. Although he and the others had done everything they could, their efforts were all for naught as they stood powerless to stop the inevitable, causing billions upon billions of innocent lives to perish in the cold and unwelcoming darkness of space.

Indignant at the outcome, Valyr asked the heavens above to give him a second chance, a chance wherein he would make sure the inevitable didn’t happen. Though he knew that the likelihood of it happening was slim to none, surprisingly…

The heavens answered.

Opening his eyes, he swiftly found out his wish had been granted, in more ways than one at that. Not only was he brought back to the time where everything had yet to unfold, he was also reborn as an NPC in the game where everything started and everything ended.

The True Immersion VRMMORPG, Greater Beyond.

Utilizing his newfound advantages, in conjunction with his knowledge of the game and its various versions from his previous life, Valyr was going to make sure that what happened before wouldn’t happen again. And all of that began…

With him picking up the Blacksmith class.

Su Shanshan died a violent death eight years into the apocalypse but somehow, she opened her eyes to find herself reborn. Time had turned back to the day before the apocalypse.

Having the chance to start over filled her with hope. Having lived through the bloody violence of the apocalypse, she now had the skills and knowledge to survive and thrive in the end times. She would repay the man who gave his life trying to save her even though she broke his heart.

The big brother whom she had reviled in her previous life. This time, she would take a chance on love.

As if blessed by the heavens, she had unexpectedly been given a spatial superpower, with which she hoarded resources that would sustain her in the apocalypse.

When the world changed in an instant on Doomsday, and hordes of flesh-eating zombies roamed the place, she set off on a dangerous journey to find him, determined to alter the course of events that unfolded and change what happened in the past.

Characters: Su Shanshan (beautiful, cold, proficient at martial arts), Gu Jincheng (rich, brilliant, awkward in affairs of the heart)
