"Wait, you mean the world will end tomorrow?" Tony Stark leaned back in the laboratory chair with a look of disgust: "And then you come to me and ask me to kill... Reed Richards?" Luke said calmly: "Yes." Tony almost spit out his coffee: "Kill Mr. Fantastic? Why don't you let me grab Thor's hammer? Are you sure you don't have a short circuit in your brain?" Tony raised his eyebrows: "I am Iron Man, not Thanos. You don't go to SHIELD or the X-Men, but come to me. Did you get the script wrong?" Luke sighed: "I have died fourteen times, and every time I woke up it was seven o'clock this morning. Believe me, Tony, I tried to call the police, report, break into the Baxter Building... and even leave a message for SHIELD, but all failed. I think the only effective way is to let Richards...

Du Mu is playing a massive virtual game called "Marvel World" for a chance to win a multi-million dollar prize. Little does he know that at the start of the game, he's already traveled to the real Marvel Universe, becoming its sole player. Nick Fury: Du Mu is an excellent agent, but he's a bit of a snob. Every time a mission is issued, he skips over it. Tony Stark: I can't believe it! The other day, Du Mu and I teamed up, and I came back with only my underwear left. Banner: I'm the exact opposite. My only underwear was stolen, and in a rage, I transformed into the Hulk, making headlines that evening. Thor: Du Mu claims he's reached 1000 Justice Points, then he raised his Meowth Hammer and ran off... Faced with the complaints of a group of superheroes, Du Mu calmly stated: "This is all allowed in the game. There are..."

Su Chen traveled to the pirate world with a magician's inheritance.

After learning most of the magic, he met Luffy who had just set sail and accepted the invitation from the future Pirate King.

What kind of collision will occur between the gorgeous and magical magic and those magical devil fruits?

Nami, come here, let me strengthen your wind-type celestial magic!

Usopp, do you know about the magic bow and various attribute ammunition?

Sanji, do you want some top-quality ingredients from around the world? And some invisibility magic?

Hey, Robin, everyone has their own meaning of existence. If you don't even have the courage to try, you don't deserve happiness at all!

After being strengthened by Su Chen, would Luffy and others still watch Ace being killed during the Battle of Marineford?

All regrets will be made up!

In the world of RE:0, the Archbishop of Sin appears.

In the world of the Shinigami, the Seireitei and Hueco Mundo are in conflict and fighting.

There is also the advent of the Yonko, Shichibukai, the Navy, and world conquest in the world of One Piece.

Even the Blue Eyes White Dragon and Blue Eyes Ultra Dragon in Yu-Gi-Oh!, the strongest lineup of the ancient Egyptian Pharaohs.

All in all, that's it. In the Fairy Tail world, I don't know since when, one after another's behind-the-scenes forces' emerged.

The big guys in the Fairy Tail world finally thought they knew the truth about the world.

Magic Council: "In other words, history is not what we see?"

Zeref, the ancestor of the black mage: "A witch who can destroy the world? I wonder if she can kill me?"

Black Dragon Acnologia...

(This book has no system, slow to start, and only has a female protagonist. Let's see how Minato becomes the strongest in the ninja world step by step!)

"Hokage-sama, Hokage-sama, may I ask how you became so strong?"

Minato thought for a moment and said, "It all started when I fell off a cliff when I was five years old. I was climbing to train, but I ran out of energy and fell off a cliff, and that's when I learned some magical skills."

"Ah? It's that simple?"

"Of course not, this is just the beginning of my legendary life!"

As soon as he opened his eyes, Rose, who knew most of the plot, traveled to the vicinity of Magnolia in the Fiore Kingdom of Fairy Tail and awakened his magic - Paladin Reception, which allowed him to receive Paladin-type Digimon. He found that there were still more than ten years before the beginning of the plot. What could he change?

Shangguan Mo traveled to the Naruto world due to an accident.

In times of crisis, the system that can synthesize summoned beasts was activated.

…

[Stone] + [Earthworm] = [Earth Dragon]

…

[Sharingan] + [Crow] = [Scarlet Moon]

…

[Asura Chakra] + [Anaconda] = [Immortal Xiangliu]

…

[Ichiraku Ramen] + [Chimpanzee] = [Otsutsuki Ichiraku]?

…

Gradually, Shangguan Mo discovered the joy of synthesis.

The five major countries: You’d better behave yourself!

Shangguan Mo: I've traveled through time, so what if I just want to be a shadow?! ?

In Naruto, you should tam beasts!

Psychic Beast: Master, stop looking, come down and join the team fight!

Shangguan Mo: Fight in a group? What group? I will never fight in a group in my life!

Summoning beast: Master, Minato Namikaze wants you to get down, he wants to kill you!

Shangguan Mo: Tsk! As for him, it would be better to call his son!!!

Psychic Beast: He said his son is only two years old...

(No system + non-Uchiha protagonist + ninjutsu development + reasonable logic)

I was reborn into the world of Naruto, but I didn't become a member of the Eye Legend. But without the system, how can I live?

Fortunately, I still remember the cultivation of immortals in my previous life. Watch me become a legitimate immortal of the human race! Develop ninjutsu, develop storm escape, and develop the immortal mode of the human race! I can become the strongest in the ninja world!

If Uchiha can implant Hashirama's cells, then as a descendant of the Senju, can't I get a Sharingan?
