After returning to Xia Manor, Xia Tian immediately entered the Ancient Sacred Realm, as he wanted to immediately process the Divine Sky Stone, because he had to burn it for a very long time first, and after that he could cut it into small pieces, only then would he can make any jewelry he wants.
Fortunately, he had the 'Sacred Heiqiong Tree', because the fire that burned its trunk would not be extinguished even if it was burned for a long time, so he could leave it in the Ancient Sacred Realm for a long time.
He immediately cut some tree trunks that were not bearing fruit, and started to burn them, then he placed the Divine Sky Stone on the fire, after which he exited the Ancient Sacred Realm.
