Lin Feng exercised the River Luo Cycle Divine Acupuncture Method in the Dark Space, using the power of the Seven Stars to shatter the Illusionary Realm and repel the Dark Giant. When he emerged from the Illusionary Realm and his consciousness returned, he discovered a marvelous change within his body.
Spiritual energy launched from the Dantian, flowed downward through the perineum, and directly ascended to the Weilu Acupoint, the first barrier of energy breakthrough, also known as the Nine Iron Drums, the gate of hell.
Only when the body's energy was sufficient would it automatically break through the barriers. Ever since Dual Cultivation with Lu Yuxin, the True Qi inside Lin Feng's body had transformed into Spiritual Energy, ascending to a higher level. Afterwards, merging with the energy of Gu Lin's Fragrant Body made his Spiritual Energy more abundant and powerful.
