Lin Fei was ravenous for knowledge in the Scripture Pavilion, reading books from morning until evening.
He not only read about the Nine Realms of Saint Dao but also studied many other books related to Saint Dao.
He learned that Saint Dao was far more profound than Martial Dao.
The most important strength indicator for a saint is the Holy Ring.
The Holy Ring is the aura of the saint.
One layer of strength is one circle of the Holy Ring, nine layers of strength means nine circles of the Holy Ring.
And every time a realm strength increases, the size of the Holy Ring expands tenfold.
Therefore, the Holy Ring of a Ninth-Layer Saint Transformation is a one-meter-nine-circle Holy Ring, and the Holy Ring of a Ninth-Layer Celestial Saint reaches ninety meters and nine circles.
