My name is Qingque, and I'm with my boss, Lord Fu Xuan.

Ever since Lord Fu Xuan went to Zhu Ming, he's been acting strangely.

The once diligent Lord Fu Xuan suddenly became lazy and liked to slack off.

Huh?! Isn't that me?

Lord Fu Xuan has become me?!

Because Lord Fu Xuan has become fond of slacking off, I was forced to take on all of Lord Fu Xuan's usual official duties and began urging him to work.

Everything is normal.

Lord Fu Xuan became me, and I became Lord Fu Xuan.

But……

But I feel that our relationship will fall into the trap of being just colleagues or superiors...

Why do I feel like Lord Fu Xuan smells so good...?

Himeko Murata has a recent problem. She thought waking up to find her entire class transformed into Herrschers was absurd enough, but... why did she wake up to find her entire class of aliens, with not a single native Earth life form in sight?! The whole class has become aliens! Kiana from Nebula M78, Bronya from Krypton, and Raiden Mei from Galife. Faced with the students' new ancestral origins, St. Freya, the Far Eastern Demon Cave, has earned a new title: the Cosmic Demon Cave. Rumor has it that even Headmistress Theresa is ecstatic.

When the card collector arrives in another world, he discovers that all the cards he needs to collect are beautiful girls. "Welcome to the true Great Millennium World!" — "Collect your own cards and challenge the will of the world!" — "Let me introduce myself, my name is Itsuka Shiori, a second-year student at Zen High School. What about you?" — "Collection target discovered: Itsuka Shiori. Card strength: 1 star (Can???)" — Intimacy? Embarrassment? Loyalty? Trust? What the hell are you trying to do?! Shikimori Kaede's collection challenge officially begins! Infinite flow, crossover anime, quick transmigration, multiple dungeons, not all combat.

Upon waking up, everyone in the world was transported to a world shrouded in fog. In this world, identity, status, and wealth are meaningless. Here, there is only one purpose: to become stronger and survive. Mo Li, a mercenary for ten years, arrived in this world with a game sign-in system. For someone like Mo Li, this world might not be as bad as imagined. [Sign in on the first day, gain the summoner skill "Smite."] [Sign in on the second day, gain the summoner skill "Sprint."]

When I woke up outside Mondstadt and saw Amber, dressed in a dashing policewoman uniform and riding that cool, three-core, phase-shifting heavy-duty police hoverbike... I knew this place definitely wasn't Teyvat. But what I hadn't anticipated was—[This uncle of Eula's has obtained certain drugs through special channels and is planning to drug his niece under the guise of an apology treat, then follow standard villain procedures. Let's bring him to justice before he commits such a heinous act!] [This is Ganyu, the half-immortal beast, the thousand-year-old secretary of Yuehaiting, Liyue's highest authority. Believing Liyue is safe everywhere, she might nap anywhere and be shipped off on a freighter and sold. We need to act quickly!] [This is General Raiden, a clueless country girl. Her first time out at a bathhouse, she's deceived by the excuse of 'what's trending'! As a partner of justice, how can I sit back and watch this happen?] I have no problem being a partner of justice, but can these outrageous things really happen? Is there something wrong with this world?

Servant Lancer Remlia Scarlet... Queen of the Night, reigns here. From now on, I will be your master, servant, are you type B blood?"

"Servant Saber Akame, in response to our previous meeting, nice to meet again, Master."

"Archer Misaka Mikoto, eh, do we know each other? Hey, hey, hey! Master, your pick-up method is too old-fashioned."

"Servant Saber, I came here in response to the summons. Well, just call me Kirito."

"Servant Archer, my name is Tokisaki Kurumi. Ah, Koizumi-kun, we are also an accomplice who saved the world together. Why are you hiding from me like this?

The arrival of a mysterious livestream disrupts the previously peaceful lives of all parties involved. Initially, they thought the market was merely a routine stocktaking, but as the video unfolds, the truth of the world becomes more apparent to those in other worlds.
