[Quick Transmigration] Why Is Everyone Fighting to Call Me Big Brother?

A kind, sincere, and silly top.

-

Qin Yuchun is an idiot. His younger brother went missing, and no matter what he does, he can't find him.

One day, a healing System bound itself to him and said that if he completed his missions, it would give him information about his brother and help him find him.

As soon as Qin Yuchun heard he could find his brother, he agreed without hesitation.

But an idiot understands nothing. All he knows is that he has to find his brother.

"He's not your brother."

The System had no choice but to summon his brother's soul and stuff it into a target's body, tricking the idiot into thinking that was his brother.

Unexpectedly, the soul it summoned belonged not only to his brother, but also to the people around him.

Quick transmigration mission worlds:

Apocalypse: The future zombie king's older brother

A strange idiot suddenly appears, chasing after the captain of the Alliance's number-one squad and calling him little brother.

"I don't have an older brother."

"How about I be your little brother?"

"You just want a little brother, don't you? I can do a better job."

Later.

Qin Yuchun thinks with his dumb head: "If I become the zombie king, my little brother won't die."

Western fantasy: The vampire's older brother

The cursed child, immortal and impervious to death, suddenly has an idiot for an older brother.

"I'm immortal. My blood relatives have been gone for ages."

"Idiot, he's the cursed child. Stay away from him and come here instead."

"Want to know about the cursed child? Make me your little brother and I'll tell you."

Later.

Qin Yuchun looks at the suffering vampire and says:

"My little brother wants to become human..."

"System, let me take on the curse."

Xianxia: The older brother of a disfigured demonic cultivator whose family was wiped out

The disfigured demonic cultivator wears a mask all year round. The dumb idiot touches his hideous face, with its exposed bones and festering flesh.

"You can't even recognize me with a face like this. I'm not your little brother."

"Look, I'm disfigured too. I'm your little brother as well."

"One of them is evil and the other is crazy. Obviously the idiot will choose me."

Later.

The righteous and demonic factions join forces, all to save the short-lived idiot who transmigrated through time and space.

(I'm trying out quick transmigration, with three worlds planned for now. In the first two, the top dies and the bottom goes mad. In the last, the top survives.)

After each mission, Qin Yuchun returns with a clue. Following the System's instructions, he goes to a park to bump into a young man.

The System gives him clues one step at a time, and Qin Yuchun follows them.

The young man really does lead him to his little brother.

But how did he end up with three little brothers?

The real world:

Crazy boy: "...This is the ultimate love I've been searching for. I'm changing my name. From now on, I'm Chunchun's little brother."

Real little brother: "Why is this idiot clinging to me..."

Little brother's little brother: "Why did my adoptive brother pick up an idiot? I heard that some Shu guy next door is obsessed with idiots too... Let me investigate."

Note:

1. Qin Yuchun is the top: a weak top, a silly idiot top.

2. Harem elements and melodramatic nonsense.

3. If this isn't for you, get out, get out, get out, get out!
