Shellwing belonged to the Fierce Things Race, which was said to have been born out of nothing when heaven and earth first came into being, gaining mighty power through Heaven-and-Earth Observation.
Half-Sage fierce things, in particular, all obtained their own Primordial Celestial Body through Heaven-and-Earth Observation.
Because their power came from observing heaven and earth rather than from any particular thing, the Fierce Things Race's power did not flow through their bodies like the blood and qi of Demon Barbarians, nor was it inclined toward the spirit like the Human Race's literary qi. Instead, it resembled magnetism, present in every part of their bodies like a force field.
As a result, some things belonging to fierce things could not be controlled using the Human Race's methods.
The Light-Brewing Bottle, for instance, was a Sacred Way treasure, so other mighty Sacred Way powers could activate it. This hexagonal prism, however, was not a Sacred Way treasure, and it also differed somewhat from ordinary unusual treasures.
"So I can only try borrowing a fierce thing's power to open it."
Fang Yun considered this, and three images emerged in his mind: the Devouring Dragon Vine, the Coffin-Bearer, and Three Thousand Eyes.
Soon, Fang Yun ruled out the Coffin-Bearer and Three Thousand Eyes, those two Ancient Great Menaces.
The fierce things' method of Heaven-and-Earth Observation was very simple. They could do it naturally, sending their Divine Sense out of their bodies and into the starry sky to survey the Myriad Worlds and strengthen their power.
The more powerful Sacred Way version of Heaven-and-Earth Observation was extraordinarily wondrous, like looking down upon the Myriad Worlds.
Fang Yun knew he could not accomplish that, so he needed to borrow a fierce thing's power. Yue Kong had previously said that he carried the Devouring Dragon Vine's aura.
