Reaching the level where he could forge Pseudo-heavy treasures within a hundred thousand years was, frankly speaking, no small challenge for Cao Bing.
Before obtaining Che Houyuan's artifact-refining inheritance, Cao Bing had already extensively studied the fundamentals of artifact refining. He had even learned the craft and personally forged quite a few weapons.
He had studied both the artifact-refining methods of the Stellar Transformation World and those of the Devouring Starry Sky world in depth.
As for the artifact-refining path of the Stellar Transformation World, Cao Bing had encountered the artifact-refining inheritance left behind by Lei Wei, the creator of the "Stellar Transformation" cultivation technique, back when he was still in the Mortal Realm. Although those methods were still rather low-level compared to forging Immortal Artifacts and divine artifacts, they had given him a certain foundation in artifact refining, so learning them had not been overly obscure.
However, the artifact-refining methods of the Devouring Starry Sky world were completely different from the artifact-refining path of the Stellar Transformation World—indeed, they were almost diametrically opposed.
Although Cao Bing had gathered a vast amount of artifact-refining knowledge to study while in the Immortal Realm, and had purchased much more such knowledge from the Virtual Universe Company in the Devouring Starry Sky world, he had even spent some time learning from the Virtual Universe Company's artifact-refining masters.
Yet with Cao Bing's current methods, given high-quality materials, he could at most forge a High-grade Immortal Artifact, or perhaps a weapon barely suitable for an Immortal-level expert.
Although a High-grade Immortal Artifact could barely compare to a Pseudo-heavy treasure, the forging methods were entirely different, and their effects were not the same either. The Lord of Crafting God was a grandmaster of artifact refining; he would see through Cao Bing at a glance. It was
