[Quick Transmigration] Protect Our Big Brother!

Their elder brothers were paragons among men, yet each suffered an unavoidable disaster.

"That woman ruined him!"

This brother was struck by an intelligence-lowering halo. A sect leader, he bowed his noble head.

"He turned to smoke before my eyes."

This brother was betrayed by his own kin. The supreme ruler of the demon realm, he was left without a body.

"He has been imprisoned for a hundred years."

This brother was coveted by the Ghost King. A heaven-blessed prodigy, he was imprisoned and humiliated.

Powerless to change anything, they could only seek help from a mysterious place, paying a steep price in exchange for their brothers' complete protection...

"I've already taken this mission."

A young man sat down before them.

"Allow me to introduce myself. I'm the most meticulous, calm, and steady Host in the entire department. This is my partner, the most advanced and precise artificial intelligence in the department. We will make precise adjustments to your brothers' fates, strictly following every step of each world's timeline. With a professional spirit of service, we'll protect your brothers from every angle and fully attend to their physical and emotional well-being. It'll be scientific, reasonable, safe, and efficient!"

The voices of countless clients overlapped, voicing the same question: "Really?"

"Do I look like the sort of person who's this goofy... I mean, meticulous, and reliable... I mean, unreliable?"

Clients: ?

Host: (?⊙ω⊙`)

A few disclaimers from the author:

1. An older brother is an older brother, and a younger brother is a younger brother. Purely blood-related brotherly affection, no couples, no incest.

2. To show brotherly love, nobody gets to take their clothes off or kiss. At most, the big brother can take a bite out of the little brother's head. Biting his head is like biting a rabbit's head: there's no weird feelings involved.

3. The Host has no love in him. He's a big shot, a huge boss with no love, and he won't fall in love with anyone. If you think he's in love, he's just pretending. He can't love anyone, because he only loves his goofy AI partner, Dog System, with the deep love of a father.

4. The brothers in every world are awesome, but they can't beat fate's arrangements. Still, a brother is a brother. However many twists and turns his life takes, he's still awesome, and he keeps trying to drag his goofy younger brother close and shelter him, since the younger brother's meddling in his fate makes his actions look idiotic.

5. Though I write out of love, I'm no nuclear power plant, and the subject matter also makes it hard to get a contract. Even though there's something so sweet about a story where the goofy younger brother overcomes every obstacle to rescue his foolish older brother by swimming through a cesspit, while the older brother thinks he's safely on shore and desperately tries to stop him from jumping into the filth, I've suffered one blow after another and am feeling pretty down. Updates may be irregular...

6. But I will keep updating.

7. I haven't earned even a single cent from publishing this story or any of my others. I simply spend my own time writing the dreams I have. I type fast, but even three thousand words takes me two hours. I won't say any of that trite stuff about appreciating my work, but if you've read it and don't like it, please don't insult me. I don't make a living from this, and I don't owe anyone anything.
