The Naruto world.

Uchiha Shikichi wanted to change this messed-up ninja world, and his first step was to seize power within the Uchiha clan and occupy Konoha...

One Piece world.

From a crew member to a legendary pirate, he gradually grows stronger and more powerful, ultimately achieving his ambitions...

This is what time travel is like. The chat group just needs to exist. There are many things that Baili Chen in different worlds needs to consider. Type-Moon World: Is the Strange Belt too dangerous? Baili Chen directly projects Ryujin Ruka to burn the Fantasy Tree. Demon Slayer World: Do you have to spend money to open the Mark to defeat Muku? The Hyorinmaru in Baili Chen's hand has something to say. Monster Hunter World: Are all the ancient dragons natural disasters that cannot be avoided? Baili Chen simply hypnotizes them with Kagami Suigetsu to turn them into his own Pokémon. As for the Bleach World... Aizen: Even if your Bankai is to summon countless swords, you can't surpass the limit of the God of Death! Yhwach: A mere summoning Zanpakutō can't cause any waves in front of my omniscience and omnipotence! Baili Chen: Well said, but if I can use Bankai on all these countless swords from different worlds, how will you deal with them? 【...

That's right, someone as handsome as me must be the protagonist. Chen Nuo looked at his counterpart, who appeared before him, wearing the helmet that symbolized his Pilot identity, and couldn't help but breathe a sigh of relief. There's a cheat! This is a sure thing. (Cyberpunk, Titanfall 2, Tokyo Ghoul, Goblin Slayer, Marvel)

Wayne split into pieces and traveled through countless worlds, but he could share power and memories in different worlds. However...

Wayne: Why are you all so abstract!

————————————

Naruto Wayne: My father is the second generation! The world is under my control, and I will do it now. Who dares to disobey? Hmm? You are not conducive to harmony, right? Come on! Cook him for me!

Wayne the Weasel: Brother, you smell so good——

Celebi Wayne: Should we throw the sleeping Kyogre into the lava today? Or take Mewtwo to find out about Mew? Hey, I have a plan. How about we go steal some snacks from Ray Karakura?

Weien: Isn't that Xiao Yan? I have a Silent Flame here. Want to know more? Hey, don't leave! Tonsillitis is fine! If that doesn't work, lower abdominal heat is fine! If you don't accept my toast, I'll have to pay you back, right? It's you, prostatitis!

French strategist Wayne: Han and traitors cannot coexist! Since I've been reborn into the Three Kingdoms, I must unify the Central Plains and conquer the world! Wait... what did you say? Without a moment's mourning for Wuzhangyuan, the next person to arrive on the battlefield is Zhuge Liang in his most powerful form—hindsight?

Then why should I bother with the knitting? I’ll just give up and be done with it!

…………

The same thing about simultaneous time travel: while other schools only need to diligently cultivate, rise from the ashes, face death head-on, experience adventures, and endure countless battles, Wayne, who simultaneously traveled through time, has much more to consider, considering his shared talents and strengths. ...

A chat group called 'Takagi Akira Friendly Mutual Aid Chat Group' connects Akira who traveled to many worlds. Through the limited help of the chat group, Akira and others gained power. This is the story of Akira and others who gained power and lived in their own worlds.

Pirate Yang Cheng: Nami is my adopted sister?

Yiquan Yangcheng: What? I'm a tentacle monster, so it's okay...

Bleach, One Piece, Naruto, Digimon, Pokémon, Re:Zero - Jobless Reincarnation, Shakugan Shana, there are so many, I'll just write whatever comes to mind...

One day, Zhao Ze, who traveled to the world of Under One Person, was pulled into a strange chat group and met other Zhao Zes. Thus began a unique journey. Resident Evil: Who wants to have some fun? The T-Virus is free! Snowpiercer: I'll do it! Spirit Cage: No, I think it's good now. I'll try harder. Under One Person: Damn you! Super Power Outage: Damn you! Resident Evil: Damn you!

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.

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!

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

A very familiar time travel.

But the problem is, no matter which world you travel to, it's always hellish difficulty?

A harmonious and friendly game world, but the absolute zero zone has become a skeleton.

The free-spirited America, but due to a combination of biochemical changes, has become a zombie.

It's an anime world full of girls, but the Greatsword Demon is still a male Greatsword user.

I finally arrived in a Western fantasy world, but you're telling me it's The Band of the Hawk? Oh my god, it's Berserk!

Finally, after much difficulty, we arrived in Hong Kong Island.

But what exactly is Lanmeng Company?

...

In short, it's a group of unlucky time travelers.

Survive in worlds of various hellish difficulty levels.

And strive to tell stories that penetrate the world.
