So Yeomra Gu Yangcheon.

The eldest son of the Gu family from Shanxi Province, an orthodox clan located in a remote part of the region. He is the child of Gu Cheolwoon, a mid-ranked master among the Hundred Great Masters of Zhongyuan, also known as the "Tiger Knight."

In his youth, Gu Yangcheon was known as the troublemaker of Shanxi, earning the nickname "Like Father, Like Son" for his misdeeds. However, whether it was simply a phase or not, his talent began to emerge as time passed.

Before the infamous massacre at the Divine Dragon Pavilion, he showcased overwhelming martial prowess at the Yongbong Gathering, earning the nickname True Dragon.

Soon after, during the massacre at the Divine Dragon Pavilion, he slaughtered countless demonic sect members and prevented the tragedy from escalating, gaining the nickname So Yeomra (Little Lord of the Underworld).

For a brief period, his reputation spread across Zhongyuan due to the Martial Alliance’s internal maneuvers. However…

Not long after, his whereabouts became increasingly unclear.
