Yun Zui received Zhang Yu's promise and did not hesitate in the slightest. On the spot, he tore his robe for paper, turned blood into ink, and used his finger as a brush to write down all the cultivation art's essential formulas and various annotations he knew.
With his cultivation, he could originally have condensed them directly with magical power. Yet this gesture was meant to demonstrate his resolve to sever himself from Origin Xia.
In a short while, he finished writing. He lifted it with both hands and presented it.
Zhang Yu and Daoist Feng read through it in turn and both nodded. This cultivation art, if cultivated step by step, could lead directly to the Upper Layer. Unlike True Law, it also took bodily cultivation into account. Even if it did not involve Origin Xia's "External Body Method," it still held a certain value.
Daoist Feng said, "Fellow Daoist Yun, since you know such a method, how could Origin Xia tolerate you?"
Yun Zui replied, "Although this method is one of the sources of the External Body Method, Origin Xia must have drawn upon the methods of other sects, taking their strengths to make up for its weaknesses. It should already differ greatly from this. Besides, without certain precious materials, knowing the method is useless. And since I am bound by Calamity-Avoiding Pills, I need not fear its being leaked. What is more..."
He mocked himself. "A man like me has repeatedly taken part in external campaigns. Who knows when I may perish in battle? Origin Xia presumably has no need to give this much thought."
Zhang Yu nodded slightly. From his seat, he pointed a finger at Yun Zui. In an instant, a strand of Clear Vault Aura descended from the air and fell upon Yun Zui.
