The Fantastic Journey of Young Lei Ming

This novel is also titled The Young Calamity Becomes a Boss in an Infinite-Flow World

[Young boy protagonist, no female lead, powerful protagonist]

Lei Ming saw the older sister beside her, who was locked in the dungeon with her, pick up a camera, point it at herself, and start talking.

"Hi, everyone, I'm Youmi, a Contractor. You know, the kind who signs a contract with some higher being and then goes on adventures in different worlds.

"I'm pretty strong. I'm ranked in the top fifty in the arena for my tier, and I usually get an A or better for clearing worlds.

"I can't take on a world-ending boss alone, but I can cut down elite monsters like chopping vegetables.

"Still, the mission in this Dark Domain world hit me like a brick. Getting thrown in jail from the start was bad enough, but the guard at the cell door turned out to be the opponent I've fought to a standstill in the arena.

"But that's not the important part. The important part is that the kid from the story, the one locked up with me, killed her in an instant!

"Is my cute little jailmate actually a Calamity-class boss?

"At least the kid and I are on the same side in this Dark Domain world.

"Anyway, once I get out of here, I'm going treasure hunting. I'm not doing this lousy mission."
