For a normal Dao Fusion Realm Early Stage Peak cultivator, the thirty-six Rule Fragments within their spirit soul belonged to the same Sub-Rule.
If they wanted to break through to the Dao Fusion Realm Middle Stage, they first had to merge these thirty-six Rule Fragments into one, forming a state more concentrated than fragments.
Rules in this state displayed power far greater than Rule Fragments, and this was also why the Dao Fusion Realm Middle Stage far surpassed the Dao Fusion Realm Early Stage.
In terms of foundational power alone, it was already a step ahead, to say nothing of comprehension in cultivation techniques, physique, and essence energy.
Of the thirty-six Rule Fragments now within Chen Fei's spirit soul, more than eighty percent were Space Rule, and they were even two kinds of Space Sub-Rule.
The remaining twenty percent of Rule Fragments were twenty-two kinds of Sub-Rules.
With such a chaotic state of rules, if any other Dao Fusion Realm Early Stage cultivator came along, they could forget about breaking through to the Dao Fusion Realm Middle Stage for the rest of their life.
But because Chen Fei had the Panel's Fusion Rule function, there was no problem of being unable to break through.
In fact, in the eyes of other Dao Fusion Realm cultivators, the most difficult part was merging the thirty-six fragments into one, but for Chen Fei, this was not a problem either, because the Proficient Realm Desolate Universe God-Slaying Sword could handle it with ease.
As Chen Fei circulated the Desolate Universe God-Slaying Sword within his body faster and faster, the thirty-six rules within his spirit soul gradually gathered together, and then their edges began to dissolve.
He could not feel any obstruction at all, only a sense of water flowing into a channel naturally formed.
