"Locke transmigrated into an era where everyone had Battle Beasts. Daemons were rampant and humans were forced to build walls around their dwellings while depending on Beastmasters to keep those monsters at bay. It was time for academies to open their enrollments and Locke only had a small snake that everyone claimed was useless! ""A snake? Isn't this just a normal snake? What a useless Battle Beast."" ""What potential can a snake have? Even if it evolves into a two-headed snake that's still only Level 1 strength. You might as well continue living like any other normal folk."" ""Who are you kidding? What makes you think you have what it takes to enter a Beastmaster University?"" Locke stayed calm as countless classmates and teachers mocked and made fun of him while he turned to his System's interface. ""All Beasts Hidden Evolution Paths!"" From a Two-headed snake to a Fire-and-Ice Two-headed snake... Then to a Demonic Shadow Snake... a Bright Serpent... Before finally, evolving into Medusa..."

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.
