Naruto System in One Piece - Chapter 480: Formation Technique

What happens when a Powerful CEO in the Fashion World who already promised to marry his girlfriend, is forced to marry a woman from a lowly family, compared to his high-esteemed family background, against his wish?

Zhou Donghuang, a man from the Earth, is able to destroy any planet in the universe without lifting a finger. His supreme will can sweep across the vast cosmos in the blink of an eye. And his immortal spirit can depart from his body and wander around the universe!

In this world, orphans or just anyone without any hope for this world can apply to become a “walking target”. Their sole purpose is to be a practicing dummy for the students of the sect who train to become “Demon Hunters”. These students need “walking targets” to test their training on living, walking beings of flesh and blood.
In exchange, they will be provided with food & shelter.
Their existence value is lower than a slave, but if they manage to survive a few years they can receive a life long pension.

Xiao Han is such a “walking target”. One time he witnessed a powerful Demon Hunter disposing a demon. When the demon died, a fragment of the demon that managed to escape entered Xiao Han’s heart. No one saw that, and even Xiao Han himself only felt some discomfort for an instant.

But that thing in his heart soon gave Xiao Han visions, and the first one is of a cultivation method which allows Xiao Han to absorb damage to enhance his body. A perfect cultivation method for a “walking target”.

Guan Dounan traveled to the world of Conan, and unexpectedly found that he had a stand-in “King of Comedy” and became a stand-in messenger. However, this double actually looks exactly the same as that “little black”?

As the so-called stand-in messenger will attract each other, Conan is the stand-in messenger, Xiao Ai is the stand-in messenger, Kidd is the stand-in messenger, Xiao Lan… Oh, she doesn’t have a stand-in, but she has double A.

In addition to this, there are many stand-in messengers who choose to embark on the path of crime, and it is time to count their sins.

“Little guy, your ability is the most useless!”

“I understand, the ability of gin! It’s…”

“Yahahahah, it’s a stand-in of the same type as my comedy king.”

“Senior Guan! Hurry up and think of a way to use your invincible stand-in!”

“I Guan Dounan just want to live a peaceful life…”

(Original stand-in, based on the world view of Conan, the characters in jojo will occasionally make cameos)

(On the basis of the original case, the magic change is not limited to the pure stand-in ability, but also has supernatural, demon, and superpower elements. In short, it is metaphysics to the end.)

(Slow heat, although it sounds weird to say this, but in the early stage, I mainly laid various foreshadowings, so it will look a little dull)
