Ning Cheng surely wouldn't go to Xu Star Sect. After parting ways with Liu Fanglin and Qi Shisanxing, he deliberately disguised himself as a middle-aged man and used the teleportation array from Tai Su Ruins to reach the border of the Tai Su Sea City.
Upon arriving here, Ning Cheng didn't summon Yan Ji, who was cultivating in the true spirit world. Following the map on the Jade Slip given by Nalan Ruxue, it only took him a few days to locate the hidden teleportation array on the edge of the Tai Su Sea.
The concealment array of the teleportation array was extremely ingenious, and Ning Cheng admitted that with his current abilities, he wouldn't be able to set up such an array. If it weren't for Nalan Ruxue telling him about this place, it would have been very difficult for him to find it on his own.
After Ning Cheng entered the concealment array, he found himself on a huge sea-rock platform.
