Yuu Tōsaka, the adopted son of the Tōsaka family, later went to the Clock Tower for "advanced training." His original plan was for him to pursue a career as a magus after graduation... until he stumbled upon a game disc. After opening it, he entered the game's world and encountered Tiamat right at the start. [Quest: Fight alongside Tiamat] "Wait, why aren't you asking me to save Humanity?!" Yuu Tōsaka quickly discovered his blind spot, but he ultimately successfully completed the system quest and spent a wonderful time with Tiamat. ...After that, he journeyed through several different game arcs. In Britain, he was King Arthur's childhood sweetheart. During the Fourth Holy Grail War, he found a girl who adored him... her name was Sajo Aika. After finally completing the game, Yuu Tōsaka was about to put the disc away for safekeeping when, one sunny afternoon, the Heroic Spirits he had captured in the past arrived. The Knight King, Morgan the Fairy, Tiamat, the Root Princess... Looking at the unique Heroic Spirits before him, Tōsaka Yuu began to sweat profusely. "The Heroic Spirit I captured in the game... actually became real?!"

This noodle is so delicious! Nangong Shuoyue exclaimed, and then a ding echoed in the boy's mind. The belated cheat code had arrived. A chat group for all realms? The group owner is the collective will of the heavens and all realms? You can become stronger by spending money? Interesting... The boss pretending to be a newbie smiled happily. Gensokyo, One Punch Man, Oregairu, Overlord, One Piece, Naruto, Bleach, Akame no Kill, God Slayer, Tokyo Ghoul, Boring Girlfriend, Puella Magi Madoka Magica, K, No Game No Life...

Travel through a world invaded by disasters and awaken the sign-in system of all worlds.

He thought that signing in in this world and obtaining the power of a Ruler of Reason, which was enough for him to protect himself, would be great enough.

Unexpectedly, he was selected by the dimensional chat group and got the opportunity to sign in to other worlds!

[Ding! Congratulations to the host for signing in to the Genshin World and gaining the allegiance of the Heavenly Principle and the Four Shadows of Heaven.]

[Ding! Congratulations to the host for signing in to Demon Slayer World and obtaining the perfect version of the immortal body, which cannot be erased by non-rule levels.]

[Ding! Congratulations to the host...]

Sign in to all realms, strengthen yourself, establish destiny and reverse entropy in the gradually collapsing world.

I originally wanted to head towards the end of the trees and the sea, but I found that I met countless beauties in the process.

Kasumi no Shi: "Tsk, what an unlovable leader!"

"You left a deep impression by being a hero saving a beautiful girl, but now you want to just walk away after you've been seduced?"

Eriri: "Damn it! I was here first, and the twin tails were supposed to increase attack speed! Why don't you come up and attack!"

Esdeath: "This man is stronger than me. I can't match him in terms of strength, but I must conquer him in other aspects!"

Lei Movie: "He saved his sister, if he wanted to..."

………

He traveled through a parallel modern world. He traveled through a prosperous ancient dynasty transformed by a time traveler. When he was inexplicably transported through time for the third time, the audience in the live broadcast room turned out to be everyone in both worlds? Knowing many unconventional and magical skills, he simply chose to ignore it.

(Note: It is logical and intelligent, does not lower IQ, and does not involve vulgar plots)

I traveled through time and became Steve, the block man in MC. I had creative mode, immortality, unlimited flight, and unlimited supplies. However, this seemingly perfect power of "God" was full of limitations.

No modules or skins, no support for complex commands.

The fastest flight speed is 21 meters per second and the maximum refresh rate is 120 frames.

Apart from hearing and vision, there is nothing else.

The seemingly powerful body imprisons the mind of a mortal.

The three dimensions with infinite area but infinite repetition have become my cage.

Low-intelligence villagers and witches are all unintelligent NPCs.

Loneliness and solitude corrode the minds of mortals trapped in pixelated bodies like poison.

Just when my mind was about to collapse, I traveled through time again!

That is a majestic pass surrounded by stars on the road to becoming an immortal!

One world after another begins to welcome my footsteps, and I will eventually break out of this cage!

First World: (Heaven Covering…)

Jiang Chen traveled through time accidentally and began his journey in anime.

The world is tentatively determined to be: Naruto - Attack on Titan - Demon Slayer - Sword Art Online - Detective Conan, etc.

————

In the Naruto world, Jiang Chen obtained a system that gives him a 10,000-fold return on his disciples. As long as he teaches his disciples, he can get corresponding high-fold return rewards.

As a reward, Jiang Chen taught Hinata the black coffin of the ghost way that he brought from the world of death.

During the Chunin Exam,

Neji: "Give up, Hinata, you are not fit to be a ninja."

Hinata: "I don't want to run away anymore, Neji-nii, let's have a showdown! A faintly turbid emblem reveals an unruly and arrogant talent...Hadō no 90: Black Coffin!!!"

Everyone: "She calls me brother, but she kills me. This girl is so scary!"

(The introduction is weak, please move to the main text~)

The canonical version awakens as a vampire in "Highschool of the Dead." In "Parasyte," he fuses with Parasyte. In "Kabaneri of the Iron Fortress," he devours Kabane. In "Jiojio's Bizarre Adventure," he becomes the ultimate perfect creature. In "Akame ga Kill," he becomes a super-dangerous creature at the top of the food chain. In "Fate," he becomes the immortal evil of humanity, living from BC to the present day. In "One Punch Man," he becomes the God of Monsters and fights with the Bald Man in the Cape from Earth to Mars. —The devilish version of Saya Takagi: "Scum, devil, shameless, die!" Joseph Joestar (jiojio): "I treated you as a friend, but behind my back you want to be my dad!?" Tohsaka Rin: "What is your relationship with my mom?!" Illya: "Dad, after this Holy Grail War is over, let's go flower viewing together."

"How to become the best in the world?" "The answer is, find more women. It's best if they are all rich, all have systems, and all are your wives. No matter if they are protagonists, villains, or extras, the more the better." "When you have a harem full of concubines, you are invincible." After closing the secret book, Chen Yin realized that he was already invincible.

[Illyasviel completes the sign-in and is rewarded with a 1cm increase in height.] Illya: "???" [Tokisaki Kurumi completes the mission and is rewarded with a video of Tokisaki Kurumi's dark history. Please accept it!] Tokisaki Kurumi: "???" [Fate Testrosa completes the mission and is rewarded with a full set of Takamachi Nanoha's friendship bombardment flow!] Fate: "???" [Shirai Kuroko completes the mission and is rewarded with a lunch box of Misaka Mikoto's love!] Shirai Kuroko: "......!!!" Chu Chen silently watched these system hosts, who were mentally broken by the system he created, and drank his tea very calmly. "Your rewards are really not my fault. I'm only responsible for making and delivering the system. You blame me for being so cruel..."
