To those who are finding the attributes in his system still confusing let me explain.
Imagine degree of taofication as his level cap.
Primodial spirit value is his current level.
The divine map is the class he chose.
So because his level cap limit (degree of tao) currently is at 0%, therefor he can only increase his level ( primordial spirit power)to a maximum of 99. When he raises his level cap limit he can naturally increase his current level as well.
The class (Divine map) gives him skills to use basically. However for him to activate certain skills, he need to train those skills in order acquire them along with meeting certain level requirements, which can only be made by increasing his level cap.
This is what the power of this world is in summary.
His cheat basically allows him to skip training and practising and directly acquire class skills while increase his level, level cap.
