Sun Yu was a first-generation apprentice from the Extreme Martial Arts Hall, and he had once served in the Intelligence Department, executing many Alien Races lurking within various large Sanctuaries.
He had also taught at the World Tree Academy, a group of students only a few years younger than himself.
He also held a position at the Extreme Martial Arts Hall as an on-staff first-tier instructor.
On Earth, as the Alien Race who hid and fled were being killed one by one, and the Alien Race hadn't made any significant moves in recent years, work at the Intelligence Department had become much more leisurely.
Recently,
Sun Yu received a mission to travel to various Human Clan gathering areas in the Mountain and Sea World under the identity of a disciple of the Tao Sect.
The Mountain and Sea World, with his current mid-upper-tier status, he had long been informed.
However, it was his first time traveling to this world.
