(Slow heat + time travel + previous civilization + Mei Yi single female lead + main plot)

"Haha, I found you, Mei!"

Mei pouted in frustration: "Oh, you found it."

"I have 'Mei's radar', I can find you no matter where you hide~"

"I don't believe it unless we play another round!"

"Okay, let's play another round. This time I'll count and you hide."

......

"You said...you wouldn't lie to me..."

"You...big liar!"

She held the photo tightly in her hand, as if it was her only support.

"You said... you would come back... you said..."

"Achen...where are you..."

......

He promised everyone that he would bring back the girl who was as beautiful as a flying flower;

He promised everyone that he would try his best to leave more fire for mankind;

He promised everyone that no matter how much it cost—

Humanity...will definitely defeat the Honkai!

Ye You travels through "Date a Live" and becomes a male elf, and the beautiful girl Gokawa Shiori wants to capture him. Meanwhile, he's invited to join the Dimension Chat Room. Everyone in the chat room is full of opinionated individuals. Grand Assassin Kato Megumi: "King Hassan says that perfect stealth is achieved by killing everyone you see, but I'm not entirely convinced." Nanoha: "@Akami Homura, Witch's Night? I'll go help you." Dr. Roman touches the Greater Holy Grail: "Magic☆Meli exists" (a look of affirmation). "Chiba's Fallen Holy Black Cat" descends upon Mondstadt to confront the Queen of Judgment in the Pure Land of the Night. Ye You records Fischl's voice and gives it to Fu Hua, revealing his past memory loss. Bronya chases Ye You on a motorcycle, seething with anger: "What did Seele mean by taking on your form?" Ye You shrugs and smiles, "The higher the dimensional disturbance value, the more powerful the chat room becomes. The happier we become!" In short, it's all about stirring up trouble.

I'm in the Honkai world, having just traveled through time. The question is, what's with this strange narration? [Take off! Take off! Such a wonderful start! Looking at this opening, you feel like your life is about to reach its peak.] No, it doesn't feel like it's taking off at all. Besides, the Honkai world is notoriously unfriendly to ordinary people, right? (╯‵□′)╯︵┻━┻. [There are many beautiful Valkyries to choose from.] [Even if you want to go big, there are Honkai Gods, Soulsteel Mini-Bishops, and Cyborgs as well.] [You feel like you're already fired up!] Not at all... Wait, Otto, you can do that? [Changkong City! The place where destiny begins! This is the perfect place for you to take your first step after traveling through time!] [Defeat the Herrscher of Thunder, then collect the Herrscher of Void and the future Herrscher of Reason into your crystal palace—the world is mine!] Wow, with this setup, you want me to go head-to-head with the Herrscher? I get it. You probably want me dead.

Is Meltlilith the most popular girlfriend in Chaldea? Or the tsundere, easy-to-win Black Jeanne? Or the furry, adorable, and invincible Fou? Or the three-formed Cosmic Demon King, Kama! And even Chaldea's cutest Astolfo will join the fray. Top 4: Ocean Atlantis, the Age of Gods! Top 3: The Interstellar City of Olympus! Top 2: Queen Morgan, the protector of Britain. Top 1: Gurren Lagann: Crimson Eyes.

I never imagined I'd travel through time one day, never imagined I'd become a character in an anime, and even more never imagined I'd end up on this land filled with suffering. "Magi-ya-baku-nai!" Kanna stretched out her short arms, snatched up a passing Originium bug, and then swallowed it whole in one gulp before patting her soiled clothes...

Also known as: "I am possessed by Ying Jie and my personality is split every day"

Mu Bei traveled to the continent of Teyvat with the Yingjie possession system.

The first thing I saw was the pink fairy lady who was as gorgeous as flying flowers.

"You have to believe that a cute girl's heart can do anything♪"

So there was a pink fairy grocery store in Mondstadt, which didn’t sell groceries but was only there to help people solve problems.

"The owner of that shop is so nice, and he always likes to put musical notations at the end of his letters. I'm going there again next time!"

"What? You're asking about Noelle? She's working as a clerk in that store."

Later, cats in Mondstadt began to disappear mysteriously frequently, and the Fatui envoys from the Goethe Hotel frequently reported thefts, which gave the Knights of Favonius a headache. This was until Diona, the bartender at the Cat's Tail Tavern, broke down and came to Jean, shouting that there was a thief who attacked her late at night and she was not after money, but only wanted to pet the cats!

Everyone knows that the new female archer adventurer who came to Mondstadt and never misses her target can learn music from Venti like an artist, and talk about alchemy with Albedo like a senior scholar. She even has a seizure occasionally, rushing into the Hilichurl camp roaring and howling, leaving wailing everywhere she goes.

Her best friend, Bennett, scratched his head at this.

"Why does Mu Bei always like to beat up the hill people while yelling for Brother Jie to stop?"

I can't find the cover

End of the world.

The collapse completely came, and the only "human" in the vast land died at the hands of a breakthrough-level collapse beast.

His consciousness gradually faded away, and when he opened his eyes again, he saw only a grid of cells...

Su Luo travels to a world with rudimentary game play and acquires the near-bankrupt Mihoyo. Simultaneously, the crossover cheat code launches, allowing him to connect to the game's production system. But upon arriving at the studio, he discovers that Mihoyo's employees are nothing more than in-game characters. Facing the familiar faces, Su Luo decisively decides to produce Honkai Impact 3rd. Kiana asks: "Why did everyone start calling me Paramecium after playing Honkai Impact 3rd? How can I quit?!" Youlan asks: "Silly goose?" "Who's that? Is that you, Kiana?" Jizi asks: "Boss... It's bad enough wrapping up so early, but you keep pushing me out and throwing knives at me later. Is that really okay?" "The Last Lesson" devastated players, while "Sky Meteor" moved them to tears. Honkai Impact 3rd's monthly sales continue to soar. Not content with this, Su Luo embarks on a new Honkai Impact 3rd metaverse project: "Kiana Comes to Sekiro," "Rita's Journey in The Witcher 3," and "Master Fu Hua's One Punch Dark Journey to the West."

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..."
