Matthew traveled to "Harry Potter", only to find that the world was facing the invasion of various foreign evil gods:

The "Dimensional Devil" that rules purgatory, the "Eyes of the Abyss" that dominate the spirit world, the "Paradox Devourer" that occupies the void...

There is also the "Blood Lord" who stole his chance to travel through time and whose strength has undergone a qualitative change...

There are suddenly many evil cults in the world. They are the root of the old beliefs and the anchor point for the invasion of foreign gods.

Fortunately, the system has awakened an incredible wisdom!

Yes, you read that right! The system has given itself a cheat code!

And as the host...Matthew can completely skip the comprehension steps and directly obtain the results of comprehension!

What does your understanding mean to my understanding? We just have different divisions of labor.

Many years later, when many evil gods were willing to burn the world to death in order to descend upon Hogwarts:

[You have come into contact with the origin of the laws of space. Due to your extraordinary understanding, you have gained the right to manage the crystal wall of the world.]

[You watched the world that was about to fall. Due to your extraordinary understanding, you mastered the endless world destruction chain.]

You can figure out the system, and leave Hogwarts to me!

Looking at the system prompt, Matthew announced domineeringly:

Evil God, get out of my Hogwarts!

…

Dumbledore: Wait, your what?

These days, without a system, even your life isn't guaranteed when you transmigrate. Fortunately, while there's no system, there's a cheat code… Ye Yu has transmigrated to countless worlds simultaneously, able to share and feedback his power with others. In the Naruto world, he faced Six Paths Madara head-on, with five thunder dragons roaring to the sky behind him. In the One Piece world, he escaped from Impel Down and shocked the world at Marineford. In the Bleach world, he ascended the throne of Heaven before Aizen. In the A Certain Magical Index world, he's a legend in Academy City, hailed as the man most likely to become a Level 6 esper. In the Detective Conan world, he possesses special abilities and is a guest of honor for many conglomerates. In other worlds, he's also a pinnacle of existence… In all these worlds, Ye Yu humbly stated that without the “strong support” of his colleagues, he would have been in a difficult situation. What…

After defeating Kabuto Yakushi and lifting all the Impure World Reincarnation of the Fourth Ninja World War, Itachi, who was burdened with countless darkness and contradictions, completely conveyed his will and love to Sasuke and left the ninja world without any regrets.

But just when Itachi thought that everything was over, he regained his 18-year-old body and came to the bottom of the Sabaody Archipelago in the pirate world!

"The Age of Discovery? Thousand Sunny?"

"You want to go to Fishman Island, 10,000 meters below? And find the end of the Grand Line?"

"You want me to be your companion?"

Luffy smiled and waved at Itachi: "This is truly a fate given to us by God, Tear Groove Man, you must be my partner."

Zoro: "Although I don't know this guy's origins, he is quite reliable."

Robin: "I am very interested in him. Maybe he is carrying a destiny that he himself does not even know about."

Akainu: "K-sou! Put a bounty on that man. Itachi Uchiha's head is worth at least 3 billion!"

Garp: "Hahahaha, I don't know where this guy came from, but the giant he summoned is really cool."

Once he traveled through the world of pirates, he became a never-before-seen fur tribe - a nine-tailed fox?

The game starts with a childlike fruit, and the side effects of the fruit are ignored?

What? The nine tails behind him still contain mysterious powers, but he doesn't know how to activate them?

Kaido: I regarded you as my successor, but you seduced my daughter?

Redhead: Why did you become UTA’s agent?

Hancock: Who is prettier, me or Xiaobai?

Everyone: Your true nature has really been exposed!

Facing everyone's questioning, the evil fox, the new admiral of the beasts, the revolutionary mentor, the best friend of the Pirate King, and the most charming person in the world, Yakumo Shiro said: I am actually just a harmless little fox! Everything is just instinct!

My name is Leggett Black.

After crossing over, I obtained a system....

It was also from this day that the world began to emit shrill screams.

Tang: Damn it, who stole my true energy!!!

Yu: "Ahhhhhhhhhhh!!! Oh my god!!!"

Jia Zhang: "Old Jia, please come back and take this thief away!!!"

In short, this is a story about exchanging everything in the Harry Potter world...

Chen Nan traveled to the Marvel world during World War II, and he was captured in a concentration camp and awakened his card-drawing cheat.

Are these all mine?

Too weak! Too weak! All too weak!!

.....

Until a boy appeared, and a few big words flashed in the dazzling golden light: [Magnetic Field Control]!

This is the story of a man who has collected countless super powers in Marvel and doesn't eat beef!!

"Hmm?" Ye Feng opened his eyes, realizing he hadn't been completely annihilated by the radiance of Apollo in the heavens. But his current situation wasn't exactly good. He was trapped in a mutant laboratory, the subject of research. "A second time traveling?" "Still a mutant." "Only awakened at eighteen..." "Fortunately, the light of the microcosm can still be ignited." Years later... The radiance of the Sanctuary enveloped the entire multiverse... Want power? Go find the sacred armor...

A seasoned manga fan, Nanao Kagura, accidentally travels to a world of jutsu while cosplaying as Kaneki Ken.

He knew the plot well but was silenced by the world's consciousness, forced to watch helplessly as his best friends walked towards their destined tragedy.

When Natsume Yuuki defected, Gojo Satoru was dejected, and in his heart-wrenching agony, he awakened the true power of a ghoul.

To save lives, he forcibly changed the plot, but suffered a backlash and dissipated.

A year later, he is reborn with amnesia and unexpectedly becomes classmates with Itadori, and encounters his white-haired teacher again—

With red eyes, Gojo Satoru pressed him against the wall: "Pretend you don't know me? Then let's get to know each other again."

Xia Youjie, who had already left, quietly reappeared and smiled, saying, "Xiao He, you broke your promise."

The moment his memories returned, the two strongest figures simultaneously reached out to him: "This time, we will break this fate."

"Holydramon is one of the four great dragons, with a majestic figure, and is the king of the sky!"

"No, no."

"HolyAngemon is one of the three great angels, merciful and kind, and is the messenger of God!"

"No, no. "

"You don't want this, you don't want that, what do you want?"

"I don't want to evolve."

This is a story about a time traveler who becomes Angewomon from Digimon and adventures in various worlds...

"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...
