Zhao Ergou transmigrates to the late years of Qin Shi Huang's reign, when the Qin Dynasty is locked in a major war with the Rong and Di tribes. He is conscripted and sent to serve as a defender.
Terrified out of his wits, Zhao Ergou kills an enemy and activates the [Level Up by Killing Enemies] System.
From then on, he keeps killing enemies as a lowly border soldier.
He wipes out the Rong and Di in the name of Great Qin, earns countless merits, achieves unparalleled military distinction, and rises to the rank of great general.
He builds the Great Snow Dragon Cavalry, ensuring that powerful Qin endures for ten thousand generations and its foundations stand firm.
He keeps expanding the territory of the Qin Empire until it stands at the summit of the world.
The protagonist is written as a proud villain, and I don't know how many people will be persuaded to quit.
The plot is great
I barely read it, but Chapter 70 is still about killing Rong Di.
