Jiang Li, a video game power-leveling player from Earth, transmigrates into the lowest of the low in a Western fantasy world: a practice-sword slave, a living target for a noble young master's amusement.
On the very first day, he's whipped in public and forced to bark like a dog.
[Ding! The Kill-to-Level-Up System is activated!]
[Rules: Kill any living creature to gain experience and drops. The stronger the kill, the better the drops.]
He counters with a slash, cutting the young master's sword in two.
From then on, while others meditate for ten years, he advances by slaughtering monsters all night;
while others painstakingly cultivate secret arts, he gets rare skills from killing a bandit.
Three levels in a day, the Saint Domain in a month. All the geniuses kneel before his blade.
But no one knows he has never been after the human rankings of geniuses
He's after the sleeping Lord of the Abyss in the Demon Abyss.
