[Urban high martial arts + designer System + power fantasy + leveling up + tsundere System + growth]

"System?!"

"What do you mean, a battle royale? I'm the only one here, so I'm the one who has to do the killing!"

"Can't you make it easier for the other players?"

"Wait..."

"What do you mean, I'm up against every player, and you've given them all Systems too?!"

"System..."

"Can't you turn down the difficulty?"

Lin Tianxia, a former special forces soldier turned game designer, accidentally transmigrated into a game. Faced with this situation, all he wanted was to go find a big truck and lie down across the road like a speed bump. (He couldn't find the exit.)

"It's all right, Lin Tianxia... As an AI with the intelligence of a young lady, A Ke has already mastered causal-layered settlement!!! Dimensional-layered suppression!!! ...And the game you created, World. Use it with caution. This young lady will bring a song of blood and fire to your world!"

"Okay... Miss AI System, from now on, I'll handle winning and you can just lie down. We'll be the lie-down-and-win duo!"

"Wait, why are the games you know so... chuunibyou?"

"What? Why are you... getting bigger as you level up? No, my upgrade resources!"

"Wait... raising you? No! I mean growing! I hope you grow up quickly!"

"That's not what I meant..."

Bonus:

A Ke's words explained: "young lady" means a mix of "girl" and "big sister."

Causal-layered settlement: Spider Solitaire.

Dimensional-layered suppression: Tetris.
