Reborn in the pre-Honkai Impact 3rd era, I became Möbius, the top scientist of that civilization, in order to overcome the inevitable end crisis of the future.

Left with no other choice, she began to work hard from her infancy, trying every possible way to keep the previous civilization alive.

However, even so, she was not 100% confident of defeating the Honkai.

Just as she was agonizing over this, she was suddenly chosen by the [Reincarnation Space], and the first world she experienced happened to be... 50,000 years after the destruction of the previous civilization.

Hmm, does this mean I can copy homework now?

[God Slayer + Original God + Collapse of Iron]

Semi-invincible in the early stage and invincible in the later stage, growing very fast.

After accidentally drawing a card and being struck by Aha, she woke up to find herself reincarnated as Furninna. Even worse, she had traveled to the world of the God Slayer.

Originally, Funina had planned to use the three little ones to survive until the end, but Aha rushed over and gave her the authority of water and invited her: "Do you want to be my messenger?"

Having been reborn into a different world in the Type-Moon universe, Yalin only wants a peaceful life after witnessing the collapse of the bubble economy. However, he accidentally discovers that he has simultaneously traveled through countless worlds.

Type-Moon world's Yarin: "Why is there a Holy Grail War everywhere? Aika, do you have any clue about this?"

Yarin from the Naruto world: "I've been transported to another world, akin to the Sengoku period of Japan. I will gather my forces and completely change this chaotic world. Wait, why is a shooting star falling from the sky? And there's a white-haired, white-eyed woman in front of me? Is her name Kaguya?"

In the Otherworld, Yalin: "Something's wrong with this world. Why are there abilities like hypnosis, sensitivity manipulation, and even time stop in the everyday world? They're all cheating, huh? Fine, I'm not acting anymore!"

.................

This is the story of a group of Yalin who relied on themselves.

Waking up to find yourself traversing the Star Railway is a joyous occasion, but why are there so many starships around?

After inquiring, I learned that, oh, it turns out I've transmigrated into the Iron Tomb, or rather, the Iron Tomb that has merged with the Great Black Tower. No wonder the perspective is so strange.

Hey, suddenly I felt a chill down my back, a flash of silver light, and then I lost consciousness. Gah, dead!

(Iron Tomb + Great Black Tower = Dark Secret. The protagonist will transform into the corrupted form of the Great Black Tower. Slightly yuri-oriented, OOC, crossover anime, not for those who care about historical accuracy, purely for fun. Please read without thinking and do not take it too seriously.)

Chu He, a veteran of the anime world, traveled to the world of souvenir anime and discovered he'd awakened powerful superpowers!

At first, Chu He simply wanted to earn money writing light novels, while also looking for familiar beautiful girls to date and have fun with his favorite characters.

But soon! Chu He discovered he was completely invincible!

If I were invincible, wouldn't I be able to do anything I wanted?

I'm Superman, and I'm going to protect my Earth!

This world is so beautiful! Kasumigaoka Utaha, Nishiki Chitsuka, Hayasaka Ai, Yasuhara Emma, Gokou Ruri, Nagasaki Motoyo, and over there, Goto Ichiri and Kitagawa Umi—none of them can escape!

What? I can even travel across worlds? Amazing! With so many beautiful girls, I'm overwhelmed!

Take photos at various anime landmarks, watch the girls act out famous anime scenes, and save all regrets!

I'm Superman, and I speak for myself.

As a traveler, he was supposed to travel to the continent of Teyvat.

But he accidentally came to the world of Throne of God and was rescued from the lake by the young Cai'er.

At the same time, he obtained the inheritance of the seven gods of the original gods.

Unlock the Thunder God Baalzebul at the beginning, and use his unintended strike to bring a different kind of shock to the world.

Long Haochen: "I thought I was invincible with two Gods, until I met Lin Feng..."

The Demon King: "In the face of the mighty Heaven, even I am not completely confident that I can handle it..."

Austin Griffin: "I can't believe there's someone more pretentious than me. The emergency food I've been living with day and night is actually the one who upholds justice..."

Cai'er: "..."

…

Strong, confident, calm, resourceful, decisive, knows how to make choices, knows when to advance and retreat, has twin ponytails, and can be a little arrogant. All these qualities combined in one person make her perfect!

Lin Lin, a die-hard fan of the series for over 10 years, is deeply in love with the little red devil: Rin Tohsaka.

"God! I f*** your mother! I like Rin and love Rin, but I never wanted to become Rin!!!" A twin-tailed loli roared in exasperation in the exquisite garden of the Tohsaka family.

"Mom, my sister is throwing a tantrum at her unseen friend again."

"Sakura, I..."

Since I'm here, I'll make the best of it. Sakura, I must save you! I will also bring change, change this beautiful yet cruel place...

"You told me you'd build a paradise where all races, ordinary people and infected alike, could coexist peacefully?" Chen Huijie asked him. "Yes." He looked at his Operator's Guide. [Operator Trust Improvement] Chen's Current Trust: 169 (16↑) Hand Holding 96√ Date 104√ Hug 121√ Kiss 136√? 156√▲ [Rhodes Island Main Ship Prestige: 68] [Regional Member Trust will slowly increase towards Prestige] He silently closed the Guide and added in his mind. Everyone's paradise doesn't conflict with my paradise, right?

Shiroku is reincarnated into the world of slimes and acquires the unique skill [Traveler], which allows him to freely travel through other worlds.

Soharu, Reincarnated Spider, Dungeon & Fighter, Problem Child...

"Evil God D, I've tolerated you for a long time!"

With Shiroku on her back, Spider Girl Shiroori launched a gorgeous rebellion against a certain evil god D: "Shiroku, save me!!"

Artosh: "Sorry, I didn't let Lord Shiroku use his full strength."

Without even a moment of mourning for the God of War Artosh, the one who immediately rushed to the battlefield was the great will Caruso.

Shiroku: "Have you ever been defeated, Caruso?"

"How can I build a small garden with this **insect!"

Shiroyasha: "Come and help me, Shiroku, from now on, I will give you half of my beautiful girl."

"What?"

Storm Dragon Veldora: "I fight Shiroku?"

Start in the Great Forest of Jura and build a demon country from scratch.

Sakaguchi Hinata: "I tried so hard...

【Not the original Rimuru】 【Lily】【More secondary settings】【Does not break the original CP】

Bai Xian was so angry that he died during the battle of Naruto because the opponent's ninja was too wicked. He was reincarnated as Rimuru and met the storm dragon Veldora.

Later, because of his deep obsession in his previous life, he traveled to the world of Naruto.

So... save Loli, recruit apostles, kill Danzo, and establish the Shinto religion.

Humph, now that he has become Rimuru, wouldn’t it be a pity if he doesn’t return to Long Aotian?

But... what's going on when my sister pushes me back? *^◎^*

Huh? I'm not very happy! No!
