Jiang Ping An devoted himself wholly to forging.
It took five hundred years to purify all the Immortal Materials, but when he fused the Undying Demon Bone, he discovered that the Sun Scarlet Flame Iron conflicted with it, causing the refinement to fail and the Undying Demon Bone to explode.
Fortunately, artifact refinement was unlike pill refinement. If pill refinement went wrong, the medicinal ingredients were basically ruined.
When artifact refinement failed, most Immortal Materials remained intact. At most, they would fuse together and form impurities.
Ordinary people found such situations difficult to handle, but Jiang Ping An possessed "Thousand Refinements," allowing him to separate all the Immortal Materials again.
No wonder Yun Yao was called the Yun Family's genius of a new era. The "Thousand Refinements" she had created could be called all-powerful.
This forging method combined tempering, forging, and fusion. It was the pinnacle of forging methods.
The only problem was that the Undying Demon Bone had been somewhat affected and had nearly melted away.
If not for the Undying Demon Bone's extremely powerful regenerative ability, it would have been completely ruined.
Even so, it took five hundred years to recover.
During that time, Jiang Ping An refined Immortal Materials compatible with the Undying Demon Bone from dozens of Heavenly Immortal Immortal Artifacts.
After the Undying Demon Bone recovered, Jiang Ping An began forging anew.
After another thousand-odd years, Jiang Ping An suddenly stopped forging of his own accord.
Because he discovered that if he continued forging like this, he could at most create a High-Grade True Immortal Artifact.
It would not reach the level of a Top-Grade Immortal Artifact.
Although he could use the "Weapon Enhancement Technique" to turn the Undying Demon Bone into a Top-Grade Immortal Artifact after forging it into a High-Grade Immortal Artifact—
