My name is Yotsuba Mahiro, a time traveler.

Sent to the Demonic World by an alternate-world teleportation ambassador, I became a Adjustment-Type magician of the Yotsuba clan.

Besides being born with eyes capable of replicating all forms of magic and physical techniques, perhaps my greatest supporter is my cheap mother, Yotsuba Maya.

After fifteen years in the gloomy Fourth Research Institute, my cheap mother suddenly gave him a crucial task.

"Although you're a Adjustment-Type magician of the Fourth Research Institute, you're also my child."

"So, it's also your duty to produce a worthy heir to the Yotsuba family."

It's just about carrying on the family line, a simple matter. Is the bloodline of the Ten Master Clans and the Hundred Houses enough? What if

I add your sister Miya? What if

I add the lolita from the Black Bullet world?

What if I add the assassination group from the Zelda: The Sisterhood?

What if I add a singing diva from Guilty Crown?

...

After traveling through ten worlds, he asked Maya again.

"Is that enough now? If not, I can add more!"

[Rocks Pirates] [Multiple Devil Fruits] [Multiple Female Leads] [Battle for Supremacy]

Fang Huo stumbled upon a stroke of luck and traveled to the Ancient Moon Village in the One Piece world. His soul cracked during the time travel, undergoing a special mutation and fusing with the energy of this world to form nine soul worms of the same origin yet independent.

With the first Soul Worm fusing with a Devil Fruit power, a user of nine Devil Fruits was born...

Moon-Light Fruit, Gravity Fruit, Vampire Fruit, Moo-Moo Fruit, Rumble-Rumble Fruit, Azure Dragon Fruit...

With Fang Huo's help, the Rocks Pirates appeared in the world ahead of schedule, possessing an unprecedented ultimate lineup...

Have you ever seen the Rocks Pirates, which included Red Earl, Roger, Rayleigh, and Jabba?

After Jon traveled through time, he asked himself a question: Can the Night's Watch save the Seven Kingdoms? Answer: The Night's Watch cannot save the Seven Kingdoms! So he quit the Night's Watch. After becoming a lord, Jon asked himself: Can being a lord save the Seven Kingdoms? Answer: Even a lord cannot save the Seven Kingdoms. So he challenged the Iron Throne that rightfully belonged to him! PS: The protagonist Jon Snow begins by traveling south to participate in the War of the Five Kings.

I traveled to the time when the genius war of Devouring Star just ended, and became a member of the bottom-ranked Doomsday Zone.

From the same era as the Nine Swords Master.

The future is full of challenges.

Chen Buwang felt under tremendous pressure.

Until he discovered that he could open more—

"The Tongtian Bridge, right? I'll be there soon."

A wisp of soul transmigrated into the Primordial Era, becoming an exceptional innate spiritual root—the Phoenix Tree.

Its root is extraordinary, not weaker than innate divine roots, and it is complemented by Yuan Feng.

However, it is already difficult for an exceptional innate spiritual root to gain consciousness, and transforming into a humanoid form is something the Dao does not tolerate.

Just as Qingwu was about to be struck by a heavenly tribulation lightning to erase its consciousness during transformation, Yuan Feng used its own fortune to guarantee Qingwu, allowing the transformation to succeed.

Since then, Qingwu owes Yuan Feng a great karmic debt and is thoroughly bound to it.

Without any system or external help, Qingwu does not dare to dream of dominating the Primordial Era, defeating Hongjun, or trampling the Three Pure Ones.

Qingwu only wishes to cultivate steadily, complementing Yuan Feng, and together ascend the Dao...

Reborn in the Dou Qi Continent, he actually became Xiao Li and even awakened the "Many Children, Many Blessings" system!

There's no way around it; as a transmigrator, I can't very well refuse the system, can I?

...

Xiao Yu: "I will only love Xiao Li in this lifetime."

Xiao Xun'er: "Brother Xiao Li, don't you want to take responsibility for me?"

Little Fairy Doctor: "He is the only light in my life."

Yun Yun: "You little rascal, you just want to bully me!"

Queen Medusa: "I have never submitted to anyone, you are the first."

...

Years later, Xiao Li stormed the Soul Clan, his spear pointed directly at the Soul Emperor.

"Is it you who spread rumors everywhere, saying that my Xiao clan has declined?"

Traveling through the Devouring Starry Sky. What? I became a member of the Flame God Clan? Oh, there's a system, so that's all right. "Congratulations, host! Signed in successfully, gaining a hundredfold increase in basic genes." "Congratulations, host! Signed in successfully, gaining a special life form, the Black Hole Clone." "Congratulations, host! Signed in successfully, gaining a special treasure, the Chaos Bell!" ... Invincible flow, not the Earth route.

[Legend of the Dragon King Fanfiction]

This is a wonderful era!

Soul Masters have gained even greater potential; battle armor and mechs complement each other, dazzling and magnificent, attracting heroes from all over the world like a swarm of locusts!

Su Qiu transmigrated here and awakened twin martial souls: the Holy Sword and the Holy Spear.

An invasion from the Abyss Dimension? The Holy Spirit Cult's Intention to Destroy the World?

Su Qiu stood in front of the crowd: "What are you all babbling about? Take this first!"

Excalibur, the thirteen bonds released!

“ex...calibur!”

A terrifying beam of light tore everything apart!

......

Soul Beast Race's Revenge.

Su Qiu stood guard alone, looking at Gu Yue and the numerous ferocious beasts behind her.

"Gu Yue, does it have to be this way?"

"I have no choice." Gu Yue's eyes were resolute, unwavering even with the person she loved before her: "It has to be this way!"

"Okay!" Su Qiu replied without hesitation.

"Holy Lance, pull anchor!"

The spear of the end shines!

......

P.S.: Some character designs will be modified to make the original characters more human-like.

The combat power of Soul Masters will be drastically altered and greatly increased, as the combat power depicted in the original work is still a bit too abstract.

I just want to be a human, is that so difficult?

Aoki traveled to the Demon Slayer world, obtained the system, and honestly worked hard to improve his "professional" level. Suddenly, Muzan came to him and forced him to become a demon.

After that, he had two more goals.

First, eat the scum boss, and second, find a way to turn back into a human while retaining the power of a demon.
