The base was enormous. After another five or six minutes of walking, the three of them reached their destination: a metal hall with even tighter security!
There were still large numbers of soldiers standing guard here, along with many more martial artists.
As soon as Lu Hao and the others arrived, everyone saluted. Lu Hao and the other two returned the martial salute.
After Qin Fengqing exchanged a few words with someone, a seamlessly fitted alloy door inside the metal hall slowly opened.
"This is the gate leading underground, and also the final line of defense," Wang Jinyang introduced from beside Lu Hao.
Passing through the gate and then a corridor, they entered another hall as soon as they emerged from the passage.
In the center of the hall stood a display screen roughly five meters tall and five meters wide.
Lines of huge text continually appeared across the screen.
"Urgently needed: energy stones. Unlimited purchases."
"Seeking the corpse of a peak Rank Four Earth Cave martial artist for research."
"Purchasing Rank Six martial artist hearts."
"A peak Rank Five ferocious beast discovered sixty kilometers outside the outpost. Recruiting three Rank Five martial artists to form a team and capture or kill it..."
Lu Hao's gaze was instantly drawn to the display screen.
"This is like our mission system," Qin Fengqing explained from the side. "As long as the things you obtain in the Earth Cave have value, you can exchange them through the military or at designated purchasing locations!"
Following Qin Fengqing onward, Lu Hao saw countless martial artists coming and going. Some were covered in blood, though it was impossible to tell whether it belonged to enemies or themselves.
Over a minute later, the three of them reached the end.
An enormous alloy gate blocked their path.
