[Extreme Prison Heaven-Slaying Technique, Fourth Layer, Entry Level (12/10,000)]
The Extreme Prison Heaven-Slaying Technique was unlike any Martial Technique Xu Yang had previously encountered. It was divided into nine layers: the first corresponded to the Qi Gathering Realm; the second and third to the Marrow Cleansing Realm, requiring the comprehension of Sword Intent; and the fourth through ninth layers corresponded to the Celestial Essence Realm.
Because he cultivated the Blood Prison Heart Blade Scripture, he had comprehended Sword Intent long ago. Thus, in a single night, he easily brought the Extreme Prison Heaven-Slaying Technique to the Entry Realm of the fourth layer.
Upon reaching the fourth layer, his comprehension of the Extreme Prison Heaven-Slaying Technique slowed. The Blood Prison Heart Blade Scripture and the Extreme Prison Heaven-Slaying Technique followed different paths, so he could no longer use his understanding of the former to rapidly advance the latter.
