In an alternate modern world, where people could summon their own beastly companions, His journey was anything but ordinary.As the college entrance exams loomed, He found himself the subject of ridicule for his choice of a companion – a small, seemingly inconsequential snowball known as an ornamental pet.“”Little Snowball? Merely a decorative trifle, utterly useless.””“”Why bother with a pet that lacks the capability to evolve?””“”Its potential is pitifully inadequate. It’s destined to remain stagnant for its entire life.””“”Dreaming of the Familiar Academy? Utterly impossible.””He was bombarded with questions, scorn, and derision.But what they didn’t know was his unique ability – he could unlock the maximum potential of any Beast Evolution!With a calm demeanor, he gazed at the pet panel, visible only to him.“”Hidden evolution route!””“”Queen’s Path: a route of boundless potential. It can ascend to the regal King class.””From Little Snowball to Ice Crystal Soul, from Snow Girl to Ice Blue Girl, and ultimately, the formidable Extreme Ice Queen… the transformation was breathtaking.Now, armed with the power to unleash the fullest potential of any beast, he faced his doubters with a bold challenge.“”Who dares to call my Snowball useless now?””The stage was set for an extraordinary journey, where potential defied expectations and a small snowball could ascend to royal heights. Who would have the last laugh in this tale of evolution and triumph?

There is always such a person in the world who likes to take their ex/Bai Yueguang/best friend as a stepping stone for their love.
These exes/Bai Yueguang/Girlfriends are called female supporting roles. They obviously did nothing. Just because they were involved with the male and female protagonists, they were trampled on, hurt, and even left a shadow that will never go away for a lifetime.
Jiang centrifugally felt sorry for those innocent girls, so he traveled from one world to another to help them cross that hurdle.
However, after a certain world, the mission is obviously wrong.
Jiang Li: “I will treat you well.”
“It’s not enough.” The girl imprisoned Jiang Li in her arms, breathing warmly: “Don’t leave, you must always be good to me, only to me.”
Jiang Li: ? ? ?

- Description from novelbuddy

A man who had emerged from the world’s most secure prison—God of Death Island, known as a super-powered being called the God of Death, had grown tired of the bloody storms abroad and now, like a hidden dragon, he had returned! But due to an accident, he became the contract husband of a beautiful CEO! From then on, he ruled the city, crushed the petty and wicked, and embarked on the tyrannical journey of an urban legend!

Garou woke up in the world of Naruto, reborn as an ordinary civilian of the Hidden Leaf Village.To his shock, he discovered he suffered from the same limitation as Rock Lee: completely talentless in both ninjutsu and genjutsu. Worse yet, he belonged to the same generation as Naruto and the other members of the Konoha 12.But Garou wasn’t the type to quit. He knew that pure grind beats natural talent.Might Guy had already proven that much.However, unlike Guy, Garou had seen the end. He had watched the anime.He understood that taijutsu, as powerful as it was, always burned out like a firework, brilliant but brief.And this time, he had no intention of going out like that.Determined to break past the limits, Garou began creating his own techniques, pushing the boundaries of what a “mere” civilian could achieve.And the mysterious light orb in his mind granted him powers based on the influence his techniques had on others and the world itself.The world of Naruto would never be the same again.The grind doesn’t stop until the world bows before his fists.
