Three Kingdoms: From Flag-Bearing Foot Soldier to Grand Commander

(Not invincible, no System, a passionate power fantasy.) A modern young man transmigrates into the Three Kingdoms era as a lowly soldier carrying a banner. Amid mountains of corpses and seas of blood, he realizes that military standards are the lifeline of the battlefield. He berates the warlords for their extravagance and reforms banner signals into the secret language of military spirit. With the “Three Colors, Nine Commands,” he stirs the flames of a chaotic age and ultimately becomes the Grand Commander who commands the armies of the realm!
