Lu Cheng put away the Black Iron Fragment. With a flicker of movement and a swish, he became a blur and vanished from the spot.
When he reappeared, he was already a hundred paces away.
Naturally, this speed was a thousand times slower than Wind Thunder Flash, but to ordinary eyes, he was already faster than a galloping horse.
In just an hour, Lu Cheng had left Yangcheng County and reached its border with a neighboring county.
Looking at the modest mountain before him, Lu Cheng drew a shallow breath and thought, Judging by the area linked together by the Dragon Whisker River, this should be the center of the entire map.
Now it all depends on my luck. If this isn't the place, I'll have to measure out this vast four-hundred-li stretch across three counties, step by step.
But he did, after all, possess the Heavenly Mandate.
As Lu Cheng approached the mountain, the iron fragment against his chest began to warm slightly.
Delight stirred in his heart. He took out the fragment and kept adjusting his direction according to its changing temperature.
Before long, he stood before a rock face.

It was even an extremely advanced one that involved space itself.
But out here in these wild mountains, with nobody maintaining it, how had the formation kept running all this time?
Questions aside, that did not stop
