Uchiha Kai: "I'm a hapless guy who traveled to the ninja world. The system is a sham used to make games and train me to be a super game producer. What kind of suffering is this?!"

System: "After testing, this is the earth in 2024. Please complete the production of the first game as soon as possible."

Uchiha Kai: "Okay, okay, you want to play it this way, right? Okay, since I'm not having a good time, let's use the Uchiha way to make the world feel pain!"

"The underworld game, start it for me!"

From then on, the ninja world had an old Uchiha thief who used the Sharingan to make the underworld game to avenge the world.

——"Fantasy Library".

A space independent of the world formed by the fantasy, curiosity, longing, yearning, regret, regret and other emotions and spirits of the world.

Here, every book is a different world imagined by others, and every page of the book is a life composed of other people's fantasies.

And if you want to make the fantasy world become real, you need to experience real life in it.

So, the administrator of the fantasy library, Aize, was chosen.

"When the fantasy life appears in the fantasy world, what is born from it is the reality."

(PS: Seven novels have been completed, "Girl's Great Summoning", "All-round Fantasy", "Infinite Death", "Miracle Summoner", "The Demon King Does Not Need to Be Defeated", "I Just Want to Be a Drama", and "Looking Forward to the Different World". It has been written for ten years, with a total of more than 30 million words. You can rest assured to read it.)

There is nothing much to say, this is a not very fresh chat group, a daily article with a complaining style.

The main text starts from Chapter 54.

The word count is not short... you can read it slowly

[ps: It was an experimental work at the time, and there were many problems. I was not able to solve them, sorry]

Bai Ye traveled through time, without a system and without an old grandfather.

Fortunately, he traveled through more than one world, but countless worlds at the same time.

Demon Slayer Bai Ye: "Boss, you scumbag? Come out and get some sun. It's not good for your health if you don't get in touch with the sun for a long time."

Heroic Spirit Bai Ye: "When we come, it's time for the stars of humanity to shine."

Greymon Bai Ye: "Puppymon, don't become like that in the future (pointing to the picture of Holydramon)".

Passerby Bai Ye: "6"

Pokemon world, God Slayer world, Ultraman world, No Game No Life world...

All Bai Ye: "I have achieved what I have today by my own efforts."

Traveled to the world of Elden Ring and became a nameless fader.

Originally, I thought that as a traveler, I could be like a fish in water after knowing the plot, but I never thought that everything was far from as simple as imagined.

The death of the first wife Mei Mutou, the stubborn teacher Se Lian always yearned for the starry sky.

After experiencing reincarnation and suffering, all this still cannot be solved.

However, at the beginning of a new reincarnation, I suddenly joined an incredible chat group.

V: "Welcome to join us, my friend."

Group Joy: "Newcomer, do you want to have some fun with Aha, ahahaha!"

Magical Girl Recruitment: "Newcomer-san, come and sign a contract to become a magical girl, and any wish of yours can be fulfilled."

Aizen: "I am the captain of the fifth division, Aizen Sosuke, welcome to join us."

Neet-ji: "Oh, it's a newcomer! Do you play Genshin Impact?"

Fire Keeper: "Excuse me, respected king, are you interested in coming to Lothric to take on the responsibility of passing on the fire and become an excellent fire king?"

"......."

Am I on a black car?

What should I do?

Waiting online, it's urgent....

Wait, did the old thief update the DLC? !

In Zoroastrianism, the mother of evil is the source of all evil and darkness!

It is said that she created the six demons of "malice", "chaos", "aging", "betrayal", "weakness" and "destruction"!

Saigo, who obtained the spirit of the 'mother of evil' in the box garden, became the 'supreme master' in Overlord;

Looking at the 'ruler of death', 'witch of the gap', 'demon of Teyvat', 'big demon of Gensokyo', 'demon of dxd', 'creator of the demon pillar' and others around him;

Saigo is sure that he has established the name of 'evil god';

In this case, he wants to shout out at the top of his lungs - God is dead!

Reed, who accidentally obtained the task system panel, was forced to embark on a mission journey wandering around the universe. Until he accepted a certain task and killed Sid Kageno in the world of "Want to Become the Powerful Shadow" and replaced him as the shadow, his life ushered in a new chapter and he embarked on the road to becoming a winner in life.

He was reincarnated and became a demon with extraordinary talents and a long life span.

Although he became an orphan with living parents at birth, he had to fend for himself and be careful of his own people and humans, but it didn't matter. At least he suddenly had a system when he was three years old, but the system was unexpectedly not very useful.

But it still made him go back to the past, made friends with Fulilian, and became the junior of the ancestor of human magic, but he soon discovered that this friend had a big prejudice against the demons.

It's okay, fortunately, the little sister of the tribe who I knew since birth-Aura has become successful, but... when I was a child, I often ordered her around, so the relationship is a little subtle.

The problem is not big, he also knows the strongest hero, but... the other party died a little early.

Just jumping back and forth between humans and demons, he gradually found that it seems that there is no side that can be relied on.

"There is no way, I still rely on myself."

He set a new life goal for himself-kill the current demon king! Become the new demon king-tentative.

Bai Jing traveled through time and thought it was just an ordinary world, but he didn't expect there would be evil ghosts that eat people.

When the evil ghost arrived, at the critical moment of life and death, he unexpectedly saw another self! And received his own golden finger!

Demon Slayer Bai Jing: At the beginning, I met Miri, and there is also a proficiency panel, Muzan, come out to bask in the sun!

Naruto Bai Jing: I have graduated from the Ninja School, and I am even about to participate in the Third Ninja World War, but why... this broken system shows that the time is when I entered school!

One Person Bai Jing: The innate ability is to control all beasts, and it is difficult to practice, but I can now copy all the innate abilities, hehe!

Martial Arts Bai Jing: Multiple wives, more blessings, wonderful!

Demon Slayer, Naruto, One Person, Martial Arts, Armor, Joy of Life, Teyvat, Fox Demon, Fighting Through the Heavens...

Time travel happens every year, and this year it's my turn.

There are infinite worlds, and there are infinite me!

Link in the world of Jackie Chan Adventures: "Since the black and positive energies can balance the combat power, when the black energy camp is dead, I can occupy all the black energy, right?"

Link in the world of One Piece: "As a marine, it's so easy to get promoted. I can make achievements along the way with Luffy. When I catch Kaido, I will be promoted directly to admiral!"

Link in the world of Hunter x Hunter: "A bunch of stinky brothers, do you understand the value of Angewomon as a mind beast!"

In Naruto, in One Punch Man, in Marvel, in Dragon Ball...

I just want to rely on myself to become the strongest in the world!
