Chapter 507: Soul Of Lightning (2).

Shi Ning was surprised to see the dark clouds gathering over the valley. This was not a common occurrence. Shi Lang was breaking into the realm of the Immortal Soul. There should not be a lightning tribulation. She did not know if this guy could endure the tribulation and wanted to return to the palace to seek help. 

Thankfully, she did not need to bother, and Elder Yu appeared behind her with a smile. He said, "Do not worry, Young Miss Shi, this is not a tribulation. This has something to do with his cultivation technique." 

Shi Ning nodded and thanked the old man. The clouds gathered together, and Lightning lingered among them. However, Shi Lang did not move or even twitch from his position. He focused on channeling all the lightning energy moving through his body. The energy coursing through his body gradually blended with the primordial soul in his soul sea.
