Inside the cabin.
Lu Heng had already refined three Eighth-Rank Heavenly Treasures of the wood, fire, and earth attributes in succession.
The three attribute channels had completed their first round of tempering. Their meridian walls had grown tough and smooth, and the amount of Dou Qi they could hold had nearly doubled.
At the same time, his muscles and bones continued to transform. His bones grew denser, his muscle fibers packed more tightly, and his pores repeatedly opened and closed, expelling layers of gray-black impurities—the stale, turbid residue buried deep in his body.
With those changes came pain beyond description.
Lu Heng gritted his teeth, fine beads of sweat forming on his forehead. The essences of three attributes surged through his meridians at once, remaking his body far more violently than he had expected.
But he did not stop.
He reached out with his right hand and touched the White Rainbow Gold Origin Stone.
An Eighth-Rank Heavenly Treasure of the metal attribute.
It felt cold. A metallic sheen covered its surface, and it weighed more than ten times what its size suggested.
The instant Lu Heng poured Dou Qi into it, countless golden lines split across the stone's surface. Sharp Geng Metal Qi flooded the meridians of his arm.
The force of it hit hard.
Geng Metal Qi was cutting by nature. The moment it entered his meridians, it began tearing at their walls. Lu Heng grunted and hurriedly activated the Five Elements Cycle, using the lingering heat of his Fire Element Spirit Domain to blunt the metal qi's edge.
Fire overcame metal.
Scorching fire-element Dou Qi enveloped the rampaging Geng Metal essence, gradually smoothing away its sharp edges before sending it into the metal-attribute channel for tempering.
The metal-attribute channel expanded rapidly.
Soft cracks came from Lu Heng's bones.
