At this moment, Ye Luo recalled a phrase, a very popular phrase in the Great Tang Empire, or rather, a term.
Border Guard!!
Why was the Great Tang Empire so prosperous, yet relied solely on its border city walls for protection?
Perhaps it was because of this special cultivation method!
Some people, in fact, were assigned the duty to defend the nation right from the start. They possessed formidable strength, but they never appeared within the country, for they had only one duty—to guard the city walls!
Border Guards, the strongest warriors of the Great Tang Empire, the most elite presence and, at the same time, the fundamental backbone of the Empire's existence!
Border Guards, directly under the control of the Great Tang Royal Family, but in fact, operate independently. Even the Royal Family could not interfere with the Border Guards' operations.
All these people in grey turned out to be Border Guards!
