Fatti, transmigrated to the world of DanMachi, starts with a fully-equipped arsenal of three magic spells and seven skills. Unfortunately, his potential is extremely limited, preventing him from seeing further. It's only after accidentally discovering a hidden treasure chest function that his life takes a dramatic turn. He opens invitations to recruit familiars from other worlds, acquiring various magic books and transforming himself from a mage into a noble sorcerer. With the goddess Demeter as his backer, he secretly accumulates strength, manages his familiar, and quietly develops his power. From then on, he cautiously and steadily begins his fantastical life in this other world.

Reincarnated into the Cardcaptor Sakura world, becoming Li Xiaoming, Li Xiaolang's older brother. Xiaoming: Xiaolang, remember, that old bastard Clow Reed is a magician who can foresee the future. The owner of the Clow Cards has already been decided. Xiaolang: Then brother, why are we still going? Xiaoming: To find you a wife. Xiaolang: ...And what about you, brother? Xiaoming: To find a wife too. (Why is the protagonist's name so bad? It's all Wang Xiaoming's fault!) Sakura has always been my childhood goddess, and I've always wanted to write a Cardcaptor Sakura fanfic. Yesterday, Cardcaptor Sakura: Clear Card ended, and many plot holes can be filled. Although it's a crossover anime, the only crossover worlds are Cardcaptor Sakura and Tsubasa: Reservoir Chronicle.

Transmigrating to a crossover anime world where gods and demons coexist, and cursed spirits dance with monsters.

He starts by copying the Mystic Eyes of Death Perception, instantly reaching max level! He'll kill even gods if they're alive! Yukinoshita Yukino: "Yukino is one thing, but why did you even... Mom..." Yukinoshita Yukino: "I'll say it again, don't call me 'sister-in-law'! I was here first!" Suo Yuki: "Big brother is mine!" Hyuga Hinata: "Luckily, I only have one sister." Otsutsuki Kaguya: "Hagoromo Hamura, come and pay your respects to your Uncle Qingping!" Lin Qingping: "At first, I really just wanted to be a kept man!"...All virgins included! A harem fantasy!

There are multiple female leads, and I'll try my best to avoid being out of character (OOC). Some pure romance anime will also be included, so please don't watch if you can't accept that. Also, some other anime that the author likes will be included as guest appearances, only appearing occasionally and not as regular characters. So please look forward to it. Finally, the main character is an indigenous person.

Having been unexpectedly transported to another world, Ye Yu initially thought he could enjoy his new life peacefully, without attachment to worldly affairs or the pursuit of immortality, only desiring a prosperous world and a peaceful existence. However, the world he encountered turned out to be Sword Art Online, and he happened to be caught in the open beta period of a game where thousands gathered—a death game. His new life began with imminent death, inescapable and unavoidable. Thus, his only recourse was to draw his sword in anger, carving out a vast starry sky where he could roam freely and roam the world. Human strength was insufficient, but fortunately, the system might be late, but it would never be absent. Bound to the God-level Choice System, Ye Yu grew increasingly powerful. After clearing the game, he returned to his daily life, expecting it to be just swordplay, but… Soubu High School, Otonokizaka… what the hell?! PS: A crossover anime slice-of-life Sword Art Online + Oregairu + Love Live! + ? ? ? ? (To be determined) This book has a relatively slow pace; those who prefer fast-paced stories should not read it.

Traveling through time and space at the same time.

In the Marvel world, he is the commissioner of the New York Police Department. He is a good official who reassures the people of New York, but a nightmare for the farmers.

Marvel White Feather: You idiots need to be electrocuted.

In the DC world, he is a doctor and a hero, starting from the "Boys", and finally breaking through the dimensional wall and entering the DC world.

DC Bai Yu: Power without legal constraints is not enough. Superman has no law enforcement power, and Batman is even more disregarding of human life...

Han Bin travels to a strange world of assassins, becoming a bounty hunter on the hands of the assassin guild.

"Are you still practicing your marksmanship? Sorry, I never open my eyes when I shoot!"

"You won't play if there's a frame?"

"Fearless Warrior, Trench Warrior, Tank Hunter, Mother of All Bombs...Activate!"

"Italian Mafia? Slavic gangs? Japanese Yakuza... Sorry, you're all just on the sidelines!"

"Mr. Wick, in this round, I'm the cheating monster."
