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*

After transmigrating through ten years and silently registering his name at the Shanmen for ten years, the system finally issued Ye Changge his first task: to take in some disciples! Disciple One: A very ordinary mortal who carries an axe every day, cutting down trees, carrying water, and usually eats ordinary food. A few years later, Disciple One left the mountain and destroyed the sky and earth as well as shattered the heavens with a slash of his axe... Disciple Two: born evil and with the appearance of a young emperor, he once traveled through the Central Region and suppressed the younger generation, with no one being of match for him... Disciple Three: the reincarnation of an empress. In her previous life, she had fought in a bloody battle to the ends of the heavens and had seen "the other shore"... In this lifetime within the Cangyun Secret Realm, Ye Changge's cultivation had reached a point where he has overcome all worldly thoughts and attained sainthood. "As a teacher, I won't be lax any longer. From today on, in the Eastern Region, I'll have the final say!" Thousands of years later, his disciples left the Eastern Region one after another. They were so powerful that they shook the mountains and rivers. Ye Changge sat on the hill alone and played the piano as he sighed, "My disciples are insane!"

"Lin Yi transmigrated into the world of Xianxia and found himself bound with a Supreme Downloading System. For a man who could not be more ordinary, he began his trip to the pinnacle of life. While everyone else worked hard to cultivate, all he needed was to press a button to download it! Be it superior cultivating manuals, superior physiques, spiritual treasures, or elixirs, all Lin Yi needed to do was press download and they would be his. Lin Yi was exasperated. It was not like he did not want to work hard, but the system itself was just too great!"

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. Just as he is about to die of old age, he suddenly awakens a cultivation system. Unlocked One-Click Cultivation System: Limitless cultivation speed boost, one major realm per second! Unlocked One-Click Technique Practicing System: Cultivation technique instantly maxed out. Cultivate 10,000 techniques at the same time! 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.
