With space as the foundation, it was easier to carry other rules, and the rule of physical strength was also one of the main focuses Chen Fei kept.
The new cultivation technique had not changed much in name, but its contents could be said to have risen by a large margin.
The most obvious sign could be seen from the technique's Proficiency.
Chen Fei had already cultivated the original Desolate Universe Rifting God Sword to the Perfection Realm, but now, with the birth of the new technique, its Proficiency plunged instantly. Not only did it fall below the Perfection Realm, it even dropped out of the Proficient Realm.
In the end, its Proficiency settled at ninety percent of the Entry Realm.
In other words, the new cultivation technique should be more than one grade higher than the original.
The original technique had cultivated two Space Sub-Rules, and now, with another twenty-two added, one technique cultivated twenty-four Sub-Rules. This was unprecedented.
Chen Fei looked at the new technique, the Desolate Universe God-Slaying Sword, and a smile could not help but appear on his face.
This technique should accompany Chen Fei for some time, because among the human race, there were no longer any Emperor Lord Realm techniques left to fuse.
If he wanted the Desolate Universe God-Slaying Sword to continue rising in level, he could only fuse Emperor Lord Realm Inheritances from other foreign races.
If this had been before, Chen Fei truly would not have had any good methods, because even if he killed a foreign race cultivator, they would not keep their own race's Emperor Lord Realm Inheritance inside their Dao Artifact.
This was not a question of whether other races could cultivate it or not. Rather, if a cultivation technique was leaked outside, other races might very well
