Back in the Gray Scale, Fu Ming had warned that fusing Forbidden Artifact Fragments from the Real World with the Power of Rules would make one unable to escape the Origin Realm, a prison on the verge of collapse.
This meant that in the future, Yang An had only one path for fusing Forbidden Artifact Fragments: find a Xianyuan Forbidden Artifact Fragment in the Xian Origin Land and fuse it with the Power of Rules from the Xian Origin.
That way, he wouldn't be tied to the Origin Realm. If disaster struck the Origin Realm in the future, he would remain unaffected.
Even the Purification of Forbidden Artifact Fragments would require a Xianyuan Forbidden Artifact as a base to devour fragments from the Real World. This was the only way to ensure the hidden dangers were removed.
This way, no matter what kind of Power of Rules he obtained in the Xian Origin Land, it would be easier to find a corresponding one in the Real World; he wouldn't be starting from scratch.
