Dragon’s Son Changsik

From Baka-Updates:
The Golden dragon has sent the legendary sword so that a hero may take hold of it and slay the Black dragon that is bound to come to destroy the world. Who could possibly become the hero of legend that is fated to have a fight of legend with the evil dragon of legend?
As it turns out, Alfonso, the elder of the village, was the one chosen. And now, as the fated hero of legend, he must take forth on his quest of legend and find the Golden dragon of Legend so he may gain the powers of legend to defeat the Black dragon of legend.
It’s going to be a legendary adventure.
