Han Wu's magical artifact, named the Panlong Robe, is only a Tier Three Middle-Grade Spiritual Artifact, yet its effects are extremely practical.
After entering the Void Heaven Secret Realm, Han Wu used the Panlong Robe to conceal himself.
For creatures below the Nascent Soul Stage, it is almost impossible to discover Han Wu's presence, other than by relying on the naked eye.
This naturally saved Han Wu a lot of trouble.
So much so that before entering the Black Sea, he only encountered one demon beast attack, and that was only because he and the beast faced each other directly and both were visible to each other.
Otherwise, Han Wu rarely fought; mostly, he only dealt with a few demon beasts proactively making their move.
Until he crossed the Valley of No Return all by himself without any danger, safely arriving at this Black Sea.
Upon reaching the Black Sea, fearing the Black Cloud Thunder, Han Wu simply decided to dive into the Black Sea and cross it directly from within.
