The 'Heavenly Compass' is extremely important to Li Yuanba, or to his true self, Li Shiming, as it purifies the 'Hell Disgust Crystal Essence' and can even condense it by absorbing radiation.
According to the information provided by the Artifact Spirit, Li Yuanba knows that the 'Heavenly Compass' can purify the 'Hell Disgust Crystal Essence' further, beyond just producing it.
The former master of the Hell Cave Heaven was satisfied with the 'Hell Disgust Crystal Essence' and didn't have the desire to purify it further.
Li Yuanba feels pleased; he discovers that the 'Heavenly Compass' addresses the basic material problem for creating a nuclear explosion.
Of course, even with the 'Heavenly Compass', it will take a long time to purify the 'Hell Disgust Crystal Essence' to weapon-grade levels.
