[The main character will not become the Saber King; there will only be a few chapters where he/she becomes a girl for fun. I couldn't think of a better name at the time, so I just used this one. The name will be changed after the book reaches 200,000 words. If you mind this, please don't read on. I'm very sorry!]

When Lynn was reborn into 20th-century London, he thought he was living the life of a protagonist in a rebirth novel.

But tell me, what the hell is magic in this world?!

As Lynn gradually accepts everything and prepares to enroll at Hogwarts to learn magic and fight Voldemort.

Tell me what the hell a magic circuit is!

Fate is here, right?! Does that mean we'll have a Holy Grail War next?

Screw the Type-Moon universe, I'm quitting, I'm giving up!

My name is Ivan, a time traveler, male, with average combat power, and a talent for being funny. However, the mission requires me to kill the immortal demon king, so... I can only be a gigolo!

Selia: Damn it, why is it that every time I have these unnecessary emotions because of you?

flamme: Why didn’t you tell me earlier that you and selia had a child!

frieren: What exactly is this sour feeling in my heart?

frieren: Woohoo, I’m really not a big mushroom...

Aura: Loyalty!

After awakening his past life memories, Cui Yunzhou finds himself transmigrated into the world of the Dragon Clan, possessing an S-rank bloodline. He knew that the Blood Sorrow would bring an invitation, but he never expected it to be… [Do you want to understand the meaning of life? Do you want to truly… live?] "An invitation from the Supreme God?" He thought this was unexpected enough, but then… looking at his teammates: the Uchiha brat, Dio the beast, the Bleach elementary school student, the passing knight… Cui Yunzhou smiles. Worlds: One Piece, Dragon Clan, Fusion Terror: Gonjiam.

After traversing the Gu Realm, Fang Xiaoyuan became an outer disciple of the Blood Saint Sect, a sect of the Blood Path.

The internal situation of the Demonic Sect is turbulent and unpredictable, with fellow disciples scheming and plotting against each other.

With his low aptitude and lack of background, Fang Xiaoyuan faced even greater difficulties within the Blood Saint Sect.

Just when Fang Xiaoyuan was feeling utterly hopeless, the long-awaited Multiverse Chat Group finally arrived, and all the worlds where the group members lived became resources for his growth.

······

Feixue: The Devouring Beast that can keep resurrecting is just a snack for your Gu worms!

Nie Xiaoqian: You blasted the thousand-year-old tree demon that sucks people's souls to the Western Paradise?

Empress of the Illusionary Sound Pavilion: Li Xingyun? What the hell?! I don't want to accompany him as he grows up!

Feng Shayan: I heard you're very strong, come and fight!

······

Unbeknownst to many, a demonic giant rose rapidly, eventually dominating all realms!

Upon waking up, Kitahara Kaede found himself transported to the Naruto world. He initially thought he'd spend his life as a cannon fodder Chunin, but unexpectedly, he awakened a diary system! By recording in his diary, he could easily access various bloodlines, ninjutsu, and divine artifacts. However, he gradually noticed that the world's style was becoming increasingly strange. Why did Uchiha Sasuke awaken the Sharingan ahead of time? Why did Uzumaki Naruto master Sage Mode beforehand? How come Uchiha Itachi was still alive and well? How come the Otsutsuki clan had arrived so early? Uchiha Sasuke: This time, I'll be Hokage! Jiraiya: This time, I won't die at Nagato's hands! Uchiha Itachi: I'll help Sasuke clear all obstacles! Hatake Kakashi: I'm never going to be a 50/50 player again! The style of this world is getting weirder and weirder.

Traveling through the pirate world, he was swallowed by the King of the Sea at the beginning, and then awakened the god-level [Cube Fruit]!

Everything in the world can be decomposed and reassembled! Others work hard to develop fruits, I directly read the data and synthesize it with one click!

While the navy was still showing off their pacifism, my 100-meter Diamond Gundam had already been assembled.

Everyone thought I was adventuring on the Grand Line...

They don’t know that every time I arrive at an island, I copy the data of the entire island!

The Battle of Marineford breaks out, and the eyes of the world are focused on the execution platform...

I printed a "Sky Island" directly above the Navy Headquarters! ?

[I want them all] [Shido gender-swapped Shiori] [Love slice-of-life] [Invincible]

As a typical otaku on Earth, I woke up to an unfamiliar ceiling and the system's voice in my ear, not knowing what to do.

Shiori: You've helped me so much, I don't know how to repay you.

Origami: If Xiaoye-kun wants it, that's fine.

Kurumi Tokisaki: Let me eat you, Yoru-kun.

Note: [We will subsequently travel to other worlds]

Chobits. Blue Sky.

Transmigrating into the world of Naruto, he becomes Tsunade's subordinate, but the system's mission demands he become the strongest medical ninja in the ninja world. Thus, Hoshigen Chisaku declares: "I am the man who will become the strongest medical ninja!" Years later, Hoshigen Chisaku questions: "What? Becoming Tsunade's man doesn't count as completing the mission?"... Disclaimer: Single female lead Tsunade, pregnancy expected~~

The mysterious transmigrator, Isayama Yuki, avoided Nawaki's inevitable death due to his close relationship with Tsunade… but he never imagined the price would be his own. Fortunately, his timely refreshed [skill] allowed him a second chance. In the first week, his vision gradually penetrated the matter before him; to avoid eye strain, he could only gaze at the sky at a 45-degree angle… In the second week, he saw that everyone had a number above their heads. However, compared to exploring the meaning of these numbers, he felt this ability had another use… Hey, Mr. Hatake Sakumo, you're indeed skilled at concealment, but the number above your head is just too conspicuous!!

Born frail and prone to illness, Baizhi lived in a small hospital room with two wishes: to continue living, and to experience the unknown. That night, a brilliant light streamed in from the window, ushering in a new chapter in Baizhi's life. "I'm telling you, Atalanta, awesome!" Baizhi from the Type-Moon world gave a thumbs-up. "Hegemony reigns supreme, anti-entropy reigns in this chaotic world, the World Serpent reigns supreme!" Baizhi from the Collapse world lived up to her nickname, the White Dove. "Even if I have a halo and wings, I, Baizhi, will still survive in this world!" Baizhi from the Terra world set up her Blue Flame heavy machine gun, and no one dared to speak. In Baizhi's dimension, Baizhis from different worlds resumed their daily "training." This book is known for its famous themes: "The Gold Finger Was Myself," "I Traveled Across Against My Will, Surviving in This World," "My Uncle Usurped the Throne at the Beginning, Is There Any Way Out?", and "What Should I Do to Survive?"
