I Stack Q Infinitely in the Dungeon

Shane traveled to another world and awakened the LOL skill system.

He started with a Kobold, and all the levels depended on Q.

[You killed a slime, level +3]

...

[You killed an elite Tauren, level +12]

...

Many years later, Shane's motto resounded throughout the continent.

[There is nothing in the world that cannot be solved with one arrow, if there is, then use two arrows]
