"Not something an ordinary artifact refiner can make?" Ling Yuyu's heart lurched at those words. Thinking Li Xiaoya was unwilling, he cautiously probed further.
"Correct!" Li Xiaoya knew what he was thinking and replied without hesitation, "See for yourself!" With a flick of his finger, he sent two jade slips flying into Ling Yuyu's hands!
"...!" Without another word, Ling Yuyu extended his divine sense into the jade slips. At first, his face lit up with wild joy, but then it shriveled into a bitter melon...
"You see? Those are only the requirements for some of the materials!" Li Xiaoya said mildly as he watched Ling Yuyu's expression. Naturally, he would not give Ling Yuyu the complete formulas, only the processing requirements for some of the materials. Although Ling Yuyu was no artifact refiner, he was still a nascent soul realm cultivator and possessed that much discernment. Without artifact refining attainments on Second Better's level, it would be absolutely impossible to process those materials using the specified methods. As far as Li Xiaoya knew, the only person in the world whose artifact refining skill had even approached Second Better's was Master Long, who had once lived in Tianyuan. But Master Long had perished in Tianyuan's Righteous-Demonic War hundreds of years earlier. Even the Heavenly Dao Sect's finest artifact refiner fell short of Second Better, and although the Ling Family also ran an artifact refining business, they certainly could not make these things.
More importantly, there was more to the Linked Super Spirit Cannons and Demon-Slaying Divine Soldiers than that. Some of the later refining methods required the Upper Realm artifact refining techniques Second Better had gleaned from studying the strange oval Key found within the heavenly starstone. At least in the Human Realm, no other cultivator could possibly refine them.
