Seventh-Order Suppressing Heavens was something Chen Fei definitely had to cultivate; more than half of his combat power came from it.
Now that this Seventh-Order Suppressing Heavens cultivated the Karma Rule first, then the Rule of Destruction, once Chen Fei achieved some success in it, his combat power would rise by a wide margin.
Of the remaining two comprehension slots, Chen Fei had hesitated for a moment earlier, but in the end, he still gave one slot to Raging Sky Divine Art, his primary essence-force cultivation technique.
Because his comprehension of rules was now limited by what Chen Fei's divine soul could endure, he actually could not bring out the full effect of the spiritual inspiration.
Thus, if both comprehension slots were given to earth's subordinate rules, from the perspective of cost-effectiveness, it actually was not that high.
A moment later, the spiritual inspiration in the Cultivation Room returned to normal, and Chen Fei slowly opened his eyes.
Seventh-Order Suppressing Heavens had already reached the Entry Realm, but after one portion of early-stage seventh-order spiritual essence, the Proficiency of Seventh-Order Suppressing Heavens had not increased by much.
Clearly, cultivating Seventh-Order Suppressing Heavens would be another long process.
But since he was cultivating two such powerful Primary Rules, it was only normal for it to be a little slower.
The Proficiency of Raging Sky Divine Art rose from twenty percent of the Entry Realm to thirty-five percent.
Compared with the previous Raging Sky Universe Art, the same Initial Stage Sky Opening Realm spiritual essence increased the Proficiency progress a little less.
But Raging Sky Divine Art was a Seventh-Order High-Grade Technique; though progress was slower, its actual understanding of the Seventh-Order Sky Opening Realm was greater.
As for earth's subordinate rule, weight, his divine soul had originally comprehended thirty Rule Fragments.
