Han Yongting felt that this purple-red long spear must be a Heaven Imperial Realm Emperor's Weapon, suitable for his martial path and physique, otherwise the spear would show no response at all, and he was already proficient in wielding long spears.
As for why he didn't sense it, Han Yongting thought it must be because the Artifact Spirit of the long spear looked down upon him.
After all, his Thunder War Body was only a King Body; cultivators with King Bodies found it easy to attain sainthood and not difficult to become a Quasi Emperor, but ascending to the Heaven Imperial Realm was extremely challenging.
If this purple-red long spear were a Top Grade Emperor's Weapon, it likely awaited a cultivator with an Emperor's Body, one with a flourishing destiny, or someone whose martial path had a very high compatibility with the purple-red long spear to gain its favor.
