A moment later.
A Dream Spider Clan Mahayana cultivator bowed respectfully and handed Fang Qing a jade slip.
Fang Qing took it and swept it with his Spiritual Sense. It contained all manner of methods for refining immortal artifacts. Not only did they require various immortal treasures, but the refining techniques were also exceedingly intricate.
"The crucial point is... to refine a Water Virtue immortal artifact, a water-aligned True Immortal must do the work. To refine a lightning-aligned immortal artifact, a lightning immortal must personally forge it and inscribe the talismans of the Great Dao..."
He shook his head. This was a dragon-slaying art—in today's Spirit Realm, it was utterly useless.
Still, the descriptions of immortal materials broadened his horizons somewhat.
Fortunately, the Jade Book Golden Seal also contained several methods for refining "pseudo-immortal artifacts" near the end, with considerably lower requirements.
But they required a vast amount of bloodline power to be extracted and combined with a blood sacrifice.
For that reason, most pseudo-immortal artifacts refined this way leaned toward demonic arts: seas of blood, white bones, soul refinement, and the like. Rather than immortal artifacts, they were better called demonic artifacts!
This Blood Sea Banner followed the design of one such pseudo-immortal artifact. Its true name was the Myriad Blood Sea Banner. But the Dream Spider Clan had not been powerful even back then; the entire clan had managed to refine only an artifact embryo before they were wiped out.
Before the clan's destruction, however, that precious embryo had been secretly moved. Later, this Dream Spider cultivator broke through to Mahayana, retrieved it, and finally completed the refinement.
The resources and manpower it had consumed could have bankrupted several small races like humanity!
"And after all that, they only ended up with a pseudo-immortal artifact..."
