To Qin Fengming, four or five years was far too short. If he wanted to completely resolve everything that urgently needed dealing with, it would be difficult to accomplish without several decades.
Although Qin Fengming had long since studied the scroll True Person Yiyang had given him on refining the Silver Sheath Worm's corpse into a magic treasure, setting aside the techniques within, he did not even possess several of the rare treasures required for the refinement.
Not only had Qin Fengming never seen those materials, he had never even heard of them.
Cloud Blood Stone, Li Ying Stone, Empty Bright Crystal, and Extreme Dragon Birth Fluid—despite Qin Fengming's Artifact Refining Attainment and his having read countless artifact-refining classics, he had never found the slightest record of any of these four materials.
With Qin Fengming's knowledge, such materials might not count for much in the Spirit Realm. But within the lower realms, even if they existed, they were certainly extremely rare items. Otherwise, given the breadth of his reading, it would have been impossible for him never to hear of them.
As for the Silver Sheath Worm's corpse, although True Person Yiyang seemed to have swallowed some substance from within it, Qin Fengming had carefully examined the corpse afterward. Apart from the faint fluorescent glow that had vanished, its rigidity had not changed in the slightest.
With Qin Fengming's current abilities, he could not budge it even a fraction.
Although he had made no breakthrough in four years, Qin Fengming was still delighted. The Heaven-Overturning Seal magic treasure he had obtained from Ghost Hand Venerable's disciple had been refined anew by him, and he had added several rare materials to it.
Its toughness and magic-treasure might had both increased dramatically. In terms of might alone, it was several notches stronger
