Everyone Transmigrates at Once, but They're All Old Hands

After his elbowing-the-lucky-carriage plan failed, Lin Xia transmigrated, and everything came apart.

When countless versions of himself gathered again, he discovered that every one of them was a veteran from before the story of their youth had even begun.

Dragon Clan Lin Xia: "A veteran of the Lionheart Society, the Secret Party's top enforcer. Now tell me, how do I take down a Dragon King in four years? How do I end the age of dragons in a century?"

Naruto Lin Xia: "Big Bro Hashirama is a stats monster, and Second Bro Tobirama is a mechanics monster. I've got high stats in my left hand and powerful mechanics in my right. Victory is inevitable. Give me a hundred years, and I'll make sure those Otsutsuki never come back!"

Warhammer Lin Xia: "I've told that old bastard Neoth again and again: if you can't raise kids, don't make so many! Now he wants me to go back and help him. What a joke!"

Douluo Lin Xia: "The Pope? Qian Xunji! A researcher? That's me! Kids, I'm going to block Tang San's spawn point!"

Elden Ring Lin Xia: "Conquest War, begin! I've been Elden Lord once before transmigrating, so of course I can become it a second time! Wait, why is this Carian princess Rennala?"

One Piece Lin Xia: "Some kid in a straw hat dragged me onto his ship... Yeah, you guessed it. He's Roger. He said the ship needed a cook, and now he's at God Valley. Guys, help me out here!"

Type-Moon Lin Xia: "War is an adult's business. Dragging children into war is a disgrace to adults! And Tokiomi Tohsaka, did you really not do a background check before taking in a child?"

Monster Hunter Lin Xia: "I'm in Kamura Village. What do you mean I'm the strongest one here? What do you mean my brother's going to be the next village chief? Are the three of us really going to stop the Rampage? Forget it, we'll win!"

The protagonist hasn't been born yet, but the story has already begun.
