The sound of thunder continued to roar, causing the ocean around the island to rise and fall, with howling winds signaling the approach of a storm.
Gu An had his back to Yang Jian, his divine sense enveloping the sea area spanning thousands of miles, constantly on guard against any approach by a Great Cultivator.
He wasn't worried about the celestial tribulation Yang Jian was causing, as such tribulations were insignificant over the ocean. Yang Jian's cultivation level was formidable enough that, though terrifying, it was only a threat to cultivators of lower realms.
Yang Jian still had his eyes closed, meditating in mid-air. His robe fluttered wildly as the nature's spiritual energy surged into his mouth and nose. Simultaneously, his pores expelled searing qi, enveloping him and making him appear extremely imposing.
