Four days later, in the afternoon.
Behind Low Hill, Small Hill Hollow.
Chen Mu stood atop the hill, looking down into the hollow. He gripped the Fire Cloud Gourd in his right hand and muttered an Incantation.
As the Incantation left his lips, Chen Mu felt his brow open wide, and a cool breath surged forth.
Boom!
Like a flamethrower, a stream of Blue Flame suddenly burst from the mouth of the Black-Skinned Gourd.
The flames surged, swiftly forming a massive fireball three meters across in midair.
Even the air warped from the scorching heat.
The next moment, the fireball shot out with a roar and smashed into the hill hollow.
Puff!
A muffled blast rang out.
A huge crater five or six meters wide instantly exploded open in the hollow's ground.
Chunks of half-melted black-red stone flew into the air and scattered in every direction.
Buzz!
Black Smoke billowed as Chen Mu appeared at the edge of the crater. The Spirit Armor Black Smoke around him activated on its own, resisting the still-burning searing flames.
"So powerful!" Chen Mu's heart clenched.
Good thing he had interrupted Lu Ku's spellcasting in time back then.
Otherwise, it really would have been impossible to say who would have won!
Still, the flames I unleashed seem to be stronger.
Chen Mu considered it, and a trace of understanding rose in his heart. "It should be related to the method of activation."
Lu Ku could only use his own blood as fuel.
But Chen Mu could use the Earth Spirit Vital Qi absorbed and refined through the Spirit Armor Technique.
Was this the proper way to use a magical artifact?
Chen Mu suddenly understood.
"I've gained another trump card!" Delighted, Chen Mu summoned the Gray Wall before his eyes.
