- Description from novelbuddy

In humanity’s final war against the Demon Lord, the strongest heroes fell—not by the enemy’s hand, but by their own, twisted into madness by a cruel illusion. Betrayal. Bloodshed. Despair… and then, silence.Only one person remained: Riley—the weakest warrior of them all. Powerless. Ignored. Forgotten.But he saw through the Demon Lord’s deception. The tyrant was on the brink of death—so weak even a fly could’ve finished him off.And Riley did just that, drawing every last ounce of strength to bite off the demon’s head.Victory? Not quite. A final, desperate strike from the Demon Lord pierced him from behind, killing him instantly.But fate wasn’t done with him yet.Riley awoke ten years in the past—when the online game [Apocalypse] was launched. Before demons descended. Before monsters overran the world.And this time, he wasn’t starting from nothing. He had a decade of experience—and a second chance.Even more shocking, he didn’t awaken his old D-rank Strength Boost talent.

Heavy R 18 Yuri, harem and futa and non-humans.

Aurora had been human once before. But she had been betrayed by her only love and left to die at the bottom of the abyss. But she survived. As a result - she was granted the power and authority of a god. Being the only one to see the bottom of the ‘Great rift,’ she became a supreme being - A goddess.

Using this power to turn back time, Aurora vowed to free her love from the clutches of those who had been like poison to her. She would take revenge on the Abyss Tower.

Being the elite academy it was, Abyss Tower had no equal when it came to training people. Aurora could no longer allow that to continue. So she vowed to change things. She vowed to set up another academy and challenge The Abyss Tower for the Abyss's ownership.

But with the other gods and goddesses tossed in the mix, as well as the Abyss itself acting up, things were not going to be that easy. Especially since her lover's soul no longer existed as one in the past.

The more Aurora tried to straighten things out, the more it all tangled up. Did she really mess up by reversing the time? Or was an even bigger plot being brewed in the background?

And the truth of everything lies in the flow and exchange of energies between different bodies. In easier terms - to dual cultivate.
