Sethis Kingdom was a thriving commercial trade nation, and beyond that, it was universally recognized as the most ancient cradle of human civilization, boasting a myriad of legends.
Not only did descendants of heroes settle here, but various ancient martial arts sects had also once flourished in this land.
However, with the advent of the commercial age, these ancient martial arts sects consequently declined.
The surviving ancient martial arts sects either secluded themselves deep within the mountains or confined their activities to small towns, unable to compete with the mainstream martial arts schools.
The skill that Yang Yu sought originated from an ancient martial arts sect that had endured for nearly three hundred years—Shadow Stream.
As the name suggested, this sect specialized in manipulating shadows for combat.
