Primordial Villain with a Slave Harem Novel

Transmigrated into the perilous fantasy world of Thalorind as a level 1 Commoner, office worker Quinlan arrives with only his intelligence and a peculiar, teleportation-granted gift. Unbeknownst to the inhabitants, this seemingly ordinary individual will ascend to unprecedented power, fundamentally altering the world's definition of strength. His ascent may be tied to his infiltration and rise through the ranks of a criminal organization. Initially isolated and vulnerable due to severe trust issues, Quinlan struggles with teamwork. However, he discovers that many individuals in Thalorind wear collars, rendering them incapable of betrayal. The story follows Quinlan's progression as he gains strength, accumulates wealth, engages in life-or-death battles, and encounters romantic partners. The protagonist is characterized as ruthless and capable of evil deeds, but these actions are directed solely at enemies or those he deems scum, not strangers for pleasure. The narrative does not depict the exploitation or sexual assault of slaves; instead, all women, regardless of their status, are treated with respect.
