The three Lu brothers, Zhaoshan, Zhaoshui, and Zhaofeng, have been in Mingsha Fang Market for less than two decades.
The more authoritative version says they were loose cultivators near Kongming Mountain and, being unwelcome there, ended up in Mingsha.
When they first arrived, only Lu Zhaoshan had reached the first tier of Out Dust Realm, while Lu Zhaoshui and Lu Zhaofeng were merely at the peak of Qi Refinement Realm.
Upon arriving in Mingsha, they didn't engage in any legitimate business—either standing guard for others or collecting debts.
Fang Markets forbid fighting—that's the universal rule—but for those skirting gray areas, the regulations are an opportunity to earn risky money.
The Lu brothers engaged in such activities excessively and were once apprehended by the Fang Market authorities, but, as luck would have it, they encountered a Spirit Beast siege, joined the defense, and not only had their charges pardoned but also earned considerable merit points.
