One Sword at the Start: I Will Become King in a Chaotic Era

In the final years of the Great Yong Dynasty, the Reform Upheaval tears the realm apart. Su Jin awakens in a mountain of corpses, drenched in blood, a broken sword in his right hand. The broken sword glows, able to sense the positions of pursuers, the number of enemies, and march routes—but he does not know what this means. From one man to an army, from a refugee to a warlord. In a chaotic era, he has nothing. But he has the broken sword, his wits, and people willing to follow him. — Description from novelcodex.org
