Republic Era: Starting with Iron Body Upgrades

[Extreme Path Overwhelming] + [Decisive Killing] + [National Martial Arts] + [Extreme Path Point-Adding Flow] + [Tearing Apart the Great Powers] I, Chen Lie, an honest apprentice in a medicine shop, awaken the [Extreme Path Slaughter System] from the start. Kill evildoers to gain points, consume great medicines to break through the physical body—Bronze Skin and Iron Bones, a three-meter demonic body, blood and qi like wolf smoke, all forced onto me! They say the Republic era is treacherous, and foreign guns and cannons are invincible? I refuse to believe it! Once my blood and qi become saintly, surging into a three-meter demonic body in the storm, I'll tear apart your steel battleships in front of the whole world! — Description from novelcodex.org
