An Immortal King expert finds it very difficult to obtain an emperor-grade technique, but if they merely want to acquire a king-grade technique, it is quite simple.
An Immortal Sovereign expert finds it very difficult to obtain an imperial-grade technique, but acquiring an emperor-grade technique is not difficult.
For this reason, almost no one uses a celestial-grade technique to break through and achieve the realm of 'Immortal King'; at most, they use it to achieve 'Immortal Lord'.
Once breaking through to Immortal Lord, as long as they obtain a monarch-level technique, using it to break through and achieve Immortal King will be much easier than using a celestial-grade technique to achieve an Immortal King...
Of course, if an Immortal Lord has a king-grade technique for cultivation, it will be even easier to break through and achieve an Immortal King!
Thus, the importance of high-grade techniques is evident.
