Returning back to the Star Shattering Sect with the strange wiggling tree root and two disciples, Pei Yang didn't waste any time as he went to Feng Chen and requested him to use the sect's guardian formation to set up an isolated space where he could place the wiggling tree root, something that he was more than happy to do after learning about how useful this strange wiggling tree root was for the comprehension of the Dao. Even more so when he learnt that if he didn't do so, it might end up breaking out of the interspatial ring it was currently stored in and start causing havoc throughout the sect.
At the very least, the authority Xuan Hao had given him when it came to controlling the guardian formation at the very least granted him this level of control. Allowing him to quickly set up a small, isolated space in a remote part of the Shattered Star Peaks where Pei Yang could place the wiggling tree root without it causing any problems for the sect.
