Bab 785: Chapter 748: Ancestral Beast of All Forms

"This bead is known as the [Essence of Spirit Crystal]."

A trace of pride flashed across the Princess's face, "It is the Empire's latest research achievement."

"Over a century ago, we discovered energy cores within certain exotic beasts that could be absorbed and cultivated by us cultivators."

"The energy from an exotic beast's flesh and blood can actually form Spiritual Energy Crystals within its body. Although the purity of these crystals is very low, this phenomenon caught the attention of the previous Emperor."

"After more than a hundred years of relentless research, we have preliminarily mastered the technique of [Synthesizing Spiritual Energy]. Even though it requires a lot of flesh and blood as feed, the purity of the Spiritual Energy Crystals we cultivate is very close to that of top-grade Spirit Stone in the Xuanhuang World."

Upon hearing this, surprise flickered in Xu Bai's eyes.
