Yi Yun was beside Lin Xintong and they read this shocking heritage left behind by the ancient Great Empress together.
Without any exaggerations, it was the entire Great Empress mystic realm's core.
It was the greatest wealth left behind by the ancient Great Empress.
The first volume of the "Great Empress Heart Sutra" was the general principles of the entire cultivation technique.
It described how Yang came before Yin. And when Yi Yun saw the Yang-elemental law's general principles, he was stunned, for what was written was —
"Sunrise from Tang Valley, Roaming across the World, Spreading Light Onto World, Brilliant Glorious Magnificent Luster, Ten Suns from Fusang, Who Masters Pure Yang…"
The paragraph might sound obscure, but these words, that were full of charm, were extremely familiar to Yi Yun.
These were… the general principles of the "Tai Ah Sacred Technique"!
