Chen Fei did not look at the Black Demon again, but instead sensed the changes in his body now.
Breaking through from the Dao Fusion Realm Late Stage to the Dao Fusion Realm Peak was truly a Qualitative Change.
Moreover, after condensing three large Space Sub-Rules, Chen Fei had condensed another eleven small Space Sub-Rules, bringing the Rule Fragments of this Sub-Rule to thirty-nine.
If Chen Fei wanted to control a second Sub-Rule, he would still need to increase the Rule Fragments of the small Space Sub-Rule by another sixty-nine pieces.
For this number of Rule Fragments, if Chen Fei cultivated them himself, it would take more than two hundred days. It was not long, but it would indeed require some time.
But now, within these ruins, judging by the effect of using the Rule Crystal earlier, he did not need many. Roughly another five Rule Crystals, and Chen Fei could directly master the second Sub-Rule.
And because Chen Fei now did not need to comprehend any new cultivation techniques, of the three cultivation slots, one could be given to Suppressing Heavens, and the rest could all be given to Sub-Rules.
If five Rule Crystals were used, not only would Chen Fei directly control the second Sub-Rule, even the Rule Fragments of the third Space Sub-Rule Solid would soar.
That Rule Crystal just now had increased Space Sub-Rule Solid from one fragment to eleven. It was the third main Sub-Rule Chen Fei's soul was comprehending.
If there really were another five Rule Crystals used, the Rule Fragments of Space Sub-Rule Solid would surge to eighty, which would bring him extremely close to controlling a third Sub-Rule.
Aside from the changes in Rule Fragments, the Power Rule Fragments in his physique had increased from seventy-two to seventy-six.
