The Strongest Illegitimate Son, Exiled to the Frontier from the Start

[Transmigration + Alternate History + System + Invincible]

Lu Yuan transmigrates into the illegitimate son of a martial marquis in the Great Jing Dynasty. His original host was envied by his elder legitimate brother, who ruined his martial arts talent and banished him to the frontier, where he became one of the cannon fodder battalion. By chance, he awakens the Grindmaster System: the harder he trains, the stronger he gets.

From [Basic Saber Technique (Beginner)] to [Unrivaled Tyrant Saber, One Slash Parts the River], he charges into battle with his saber held high. I alone am General Lu, a match for a million barbarians. If brains can't solve it, use brawn. How do you break the deadlock? Just kill them all.
