【【The first part is more daily, and the latter part will be involved in the plot

This book is rather original, so don't be confused if you find that the plot doesn't match.

Mo Nian traveled through time.

Inherited a small shop given by the system in a supernatural world.

I thought I could live a wealthy life by selling system products, but who knew that the customers who came seemed a little different.

Tokisaki Kurumi: "Ala Ala~ Little store manager, do you have a place for me here?"

Ikaros: "Master, what do you want to eat today?"

Saber: "Master, there's not enough food in the warehouse!"

Esdeath: "Superpowers? Interesting!"

Mo Nian: "Ah! Saber! You can't eat that!"

Then came the arrival and encounters of various characters.

Feng Baobao (dialect): "Manager, do you want this? I can take it away if Xu Si says he doesn't want it."

Yan: "Little boy, we are both angels, why don't you choose the more mature one?"

Sasuke: "Please teach me how to take revenge. I must kill that man!"

Luffy: "Ahaha, Manager, here I come again!"

And other people that Mo Nian knew and didn’t know who kept coming.

In this way, Mo Nian began an interesting life in the new world.

【System + Naruto Fanfiction + Not Brainless + Vest + Realism】

Zheng Dongfang travels to the world of Naruto, using the alias Dongfang Zhen. He gains access to a system called "Daily Card Draw," where he can gain access to all the abilities of a ninja, including chakra, ninjutsu, taijutsu, and even bloodline limits! Reaching a certain number of draws fully unlocks the corresponding ninja card, granting permanent ninja abilities!

Dongfang Zhen: I want to create a new ninja world, let me draw out Madara and the First Generation!

Life Healing, Spider Sense, Baji Grandmaster, Innate Power, The Golden Rule...

Looking at all these things signed in through the system, Bai Yunshen felt helpless.

What a useless system! They were all good things, but what good were they in this Saint Seiya world, where gods abound and gold is worth less than gold? In this world where the microcosm is the cultivation system, mastering the sixth sense to attack at the speed of sound and the seventh sense to attack at the speed of light is of no use! And then, until one day...

Congratulations to the host for signing in to [The Nature of Regulus]! So good...

(PS: This book is primarily based on the Saint Seiya world, with passages into other worlds.)

Tang Zichuan accidentally travels to the Marvel Universe and gains access to a famous scene check-in system. His newbie gift pack instantly unlocks a Golden Superman template!

Doesn't that make him invincible?

Blowing out the sun with a breath, destroying the solar system with a sneeze, defying time and killing his grandmother, even eating kryptonite...

These are descriptions of Silver Age Superman's abilities. But even above Silver Age Superman lies a supreme form of Superman: Golden Age Superman!

Golden Age Superman can defy all laws, create something out of nothing, manipulate time, space, and matter, and alter reality...

It's already a formidable start, and yet a chat group is calling him?

Call me Councillor: Fight for a better tomorrow!

Escape from Peach Blossom Island: "Who is Guo Jing? I only know Brother Zichuan!"

The Daoist Princess: "I don't want to be the Ice Lord, I just want to be Brother Zichuan's good sister."

The legendary Big Fat Sheep: "Take advantage of my luck! I don't want to lose every bet @Golden God."

Dante, the newly minted god of Aincrad, begins his journey to the next world. Three options lie before him:

become a knight of Britain,

an assassin of the Middle East,

or a warrior of ancient Greece.

Of course, it all began one night after a meteorite struck.

Worlds to be traveled to: Sword Art Online, Fate, Chikō, High School...

Han Yu journeyed through the world of Sword Art Online.

He bound to the system and gained skills.

As a gifted and powerful player, single-handedly challenging bosses was a daily occurrence.

He achieved undefeated status in SAO, single-handedly breached the World Tree in ALO, and became a legend among players.

In GGO, he slashed sniper bullets within three meters with his lightsaber, and in Uncharted Wars, he single-handedly held off tens of thousands of Dark Territory troops, becoming a player god.

Marisa is the best in the world!!! A protagonist with a system is presented to the beautiful world of Gensokyo, but he's surprisingly a noob? Eleven, armed with the system, will endure many beatings in Gensokyo... (crossed out) What kind of story will unfold between him and the girl? Incidentally, the system is a scumbag system that loves to remain invisible (crossed out entire sentence). This is a mix of the first and second settings, including some of the author's personal settings.
