Lei Qianjue walked ahead, leading Li Zhengyang through the air.
Li Zhengyang had only just advanced to the Martial Emperor level and had not yet had time to learn any flight martial skills.
A Martial Venerable was incredibly fast.
They flew from the buildings in the heart of the military district to an endless mountain range.
About half an hour passed.
A wall appeared on the horizon ahead.
Li Zhengyang froze.
The word "wall" was not accurate enough.
It was a colossal bastion that stretched beyond sight.
It stood nearly a hundred meters tall, its surface glinting with a dark metallic sheen and covered in fine patterns.
The bastion's surface was carved with countless formation patterns, similar to those in the Marrow-Washing Pool, but on a scale beyond comparison.
Every formation pattern pulsed faintly, releasing waves of energy.
Those waves overlapped, forming an invisible barrier.
Lei Qianjue stopped a hundred meters before the wall, hovering in the air with his hands behind his back.
Li Zhengyang landed beside him and stared at the wall.
"What is this?"
"Nine-Heavens Darksteel and World-Sealing Stone. The entire wall was forged jointly by three hundred and sixty formation masters."
Lei Qianjue's tone was full of pride.
"It began construction when Great Xia was first founded. By now, it has stood for nearly a hundred years."
A hundred years.
Li Zhengyang took a moment to process that number.
"What is this wall for?"
Lei Qianjue did not answer immediately.
He turned to face the direction from which they had come.
"That land you saw—from the military district to Fortress No. 7, from Fortress No. 13 to the small city where your hometown is located—is the entirety of Great Xia's current territory."
He paused.
"It accounts for only one-tenth of our original land."
Li Zhengyang's breath
