Su Lengyue could hardly have missed the look in Lin Shuguang's eyes. She immediately rolled her eyes at him and said irritably, "My ancestor's cultivation may have reached the Great Sage Realm, but mine is still nowhere near enough to activate all the wondrous powers of this precious mirror. I'll have to reach at least the advanced stages of the Great Sage Realm and drive it with primordial spirit power before I can set its inner workings in motion.
"They say there's a space inside this mirror too, but I can't activate it yet. All I'm doing now is making slight use of its mysteries to reflect things. In fact, today is my first time using this mirror. My cultivation was never sufficient before."
Lin Shuguang pondered briefly. "Do all treasures from Ancient Times require primordial spirit power?"
Su Lengyue could not guarantee it either. "As far as I know, yes, but it isn't absolute. Take your Heaven Sacrifice Talisman, for example. It probably has an even longer history than those ancient treasures. Never mind my mirror-the ancient treasures passed down in the Jade Void Palace, for instance, require even more astonishing amounts of primordial spirit power to activate.
"You could say that one or two elders alone would inevitably struggle to activate them. Only those few old monsters stationed at the sect can activate them together. Methods of cultivating the primordial spirit were lost long ago. Perhaps you'll have a chance to find one."
Those words carried a deeper meaning.
Lin Shuguang heard them clearly, however. How could he not know that little thought of Lin Shuguang's? "Help me investigate what other functions this Heaven Sacrifice Talisman has when we get back. If I obtain a Primordial Spirit Technique, I'll naturally share it with you."
Su Lengyue smiled brightly.
