Who Says I'm Not a Proper Adventurer?

Transported to a fantasy world filled with Giant Dragons, Elves, and Adventurers, Lance set three iron rules for himself: Don't join in on the excitement, don't meddle in idle matters, and don't go out after dark. ... Unexpectedly, a few months after being transported, the unconventional game he played in his past life was still pursuing him. From then on, Lance possessed endless stamina and an unending life. But in this world interwoven with adventure, dreams, greed, and danger, he, as a Copyist for the Adventurer's Guild, only wants to live a peaceful life, quietly accumulate strength, and finally go to the City of Trade, full of young ladies from the alien races, to fully display his Talent. — Description from novelcodex.org
