The next moment, ripples spread out in the space around Su Yu again.
His figure appeared beside the jade platform.
He looked at the third-grade lower-quality Mirror Moon Symbol on the jade platform, feeling the spatial and illusory powers hidden within it.
Deep down, Su Yu thought: "With this symbol, I can fearlessly face opponents in the mid-Core Formation realm."
Thinking this, Su Yu thought of two other unique second-grade higher-quality symbols; the Leithun Talisman and Immortal's Finger Symbol.
Over the years, Su Yu had been practicing the Mirror Moon Symbol, but he was also trying to create other third-grade lower-quality symbols.
From the three ancient books he had previously read, he had encountered some incomplete ancient third-grade lower-quality symbols and insights of ancient cultivators on symbols.
He had quite a few ideas on how to improve and modify the Leithun Talisman and Immortal's Finger Symbol.
