Before anyone could introduce him, Lin Shiming's divine sense had already extended far into the distance.
With his divine sense at the peak of the Golden Core realm, just a hair's breadth away from that of the Nascent Soul stage, he could cover more than half of the sea region.
In the blink of an eye, everything was clear to him.
Compared to decades ago, Yunyue Island had now expanded to over twenty times its original size.
The Spirit Vein here had also transformed into a true Sixth-Order Spirit Vein. Even standing on the island, Lin Shiming felt torrents of spiritual energy surging into his body, shaking him to the core.
The fortress city, too, was nothing short of extraordinary. It stood over a thousand feet tall and ten feet thick, constructed of at least Fourth-Order spiritual materials mixed with superior-grade Third-Order cloud iron rock.
It was the most formidable fortress Lin Shijie had ever encountered.
