The Heavenly Star Soul Jade was a treasure Lin Feng obtained from Ghost Shura Yan, a treasure that could absorb the power of the sun, moon, and stars day and night, enhancing the soul power of cultivators.
The enhancement of soul power is the most challenging, even more difficult than the enhancement of cultivation.
Because ordinary cultivators find it extremely hard to absorb the power of the sun, moon, and stars from heaven and earth.
Even if one managed to absorb it,
the power of the sun, moon, and stars, when shining down from the Nine Heavens, would absorb many impurities during the process.
If a cultivator refined the power of sun, moon, and stars containing these impurities, it would be very harmful to their soul.
Therefore, one could only rely on certain magical treasures to absorb the power of the sun, moon, and stars.
