Keeley, a simple plain Jane, hits the jackpot. [No, she did not win the lottery!] At least that's what she thinks when she marries the most eligible bachelor in New York City: Aaron, a wealthy cold-hearted heartthrob and Tycoon. She wants to show the world that she deserves her position and bends over backward to fit into his world. One beautiful day, Aaron hands her a document asking her to sign. A divorce paper... "She's pregnant, and I need to take responsibility." That is the last thing that keeps on playing in her mind before she takes her last breath. Keeley dies, a 'hit and run'. [End of story. Not!] For some unexplainable reason, she wakes up as her younger self. A young high school girl, around the time when she first meets her cheating husband. Remembering her life with Aaron before she died, she makes a promise to herself that she will do everything in her power to avoid him at all costs. Will she be able to keep her promise when Aaron has his own plans as well, specifically for her? Or will she repeat history and fall for him once more... Why not journey with me and find out the truth behind their story. *Cover art by polkadottedscrunchie*

Long ago, there were people who stood upon the earth with their heads held high. They never bowed to anyone because of their indomitable spirit. They were capable of controlling wind and lightning, and conquering dragons and serpents. They seemed strong enough to split the earth and shatter the stars with their fists. They traveled throughout the land and called themselves Magi. Eventually, one of them would become a Supreme Magus! These men are the ancestors of human beings. Their blood is what we all share today. Qing Long is the former strongest man in the world. He traveled through space and time and was reborn as Ji Hao in the Fire Crow Clan of the Southern Wasteland. It’s a complicated world.

Fate had never been kind to Ji Ning. Wracked by illnesses and infirm his entire life on Earth, Ning knew early on that he would die as a teenager. What he didn’t know was that there really was such a thing as life after death, and that the universe was a far larger place than he thought. A lucky twist of fate (one of the few in Ning’s life) meant that Ning was reborn into a world of Immortals and monsters, of Ki Refiners and powerful Fiendgods, a world where Dynasties lasted for millions of years. A world which is both greater…and yet also smaller…than he ever could imagine. He would have the opportunity to join them, and in this life, Ning swore to himself, he would never let himself be weak again! The Era he was born into was a Desolate one, but Ning would make it his era.

Lin Qi transmigrates to a world of immortals. In this world, there are sword immortals who can behead a person from a thousand miles away, peerless great demons who burn mountains and boil the seas, and ancient gods and devils who can divine the heavenly secrets. As a disciple in charge of miscellaneous chores in the Skysword Sect, Lin Qi doesn't have any cultivation talent. A hundred years had passed in a flash, and seeing that he has nothing to do with such a great world, Lin Qi is incomparably depressed.

Unlocked One-Click Clone System: 100% of the actual body's strength. Can self-destruct, can teleport, can fuse! As a result, Lin Qi begins to cultivate again with his hundred-year-old body, becoming invincible under the heavens.

When Fang Yuan was transmigrated into a world where Gu Breeder was the main profession, he found that he was not gifted. Not only that, the Gu in his body could cultivate on their own. [Your Iron Skin Gu has trained profoundly and has achieved the Gold-grade!] [Your Bloodthirsty Gu has begun to multiply itself into a swarm of Bloodthirsty Gus!] [Your Sunlight Gu has been absorbing the power of the sun for years and has gathered the Truth Flame of the Sun!] [Your Drunken Gu has evolved into a Soul-reaping Gu. Your control over it has risen by 100 folds!] [Your Flying Sword Gu was hurt in battle. Amid its desperation, it has evolved into a Sword God Gu!] “Heck, even Gu undergoes involution as well now?” Fang Yuan let out a sigh.
