He walked to the innermost sealed chamber of the laboratory and pushed open the door. Sixty soul lamps were arranged in a spiral, with a meditation cushion at the center. This was Fei Yun's custom-made Spiritual Amplification Formula, designed to help him push his Spiritual Power to its absolute limit.
After sitting cross-legged, Fei Yun began his daily release of Spiritual Power. His consciousness gradually rose, passing through layer after layer of mental barriers until it finally reached a pure white world.
This was the Void Clarity Realm, a place only those whose Spiritual Power had reached a certain realm could enter.
Inside the iron cage at the center of the laboratory was a Supreme Clan ninja with a special physique. His soul was twice as strong as that of an ordinary ninja.
Fei Yun stood at the center of a pentagram formation, with five chakra spheres floating beside him. The fusion of all chakra attributes began. His hands formed seals at astonishing speed as the five chakra spheres drew closer together. A piercing hum filled the air, and glass vessels throughout the laboratory shattered one after another. When the five chakra attributes completely fused, an energy mass shining with seven-colored light appeared before Fei Yun.
The spiritual link was established. Spiritual Power poured in. Fei Yun's eyes turned completely purple, and complex patterns emerged across his forehead.
His Spiritual Power surged toward the seven-colored energy mass like stone, causing countless microscopic chakra vortices to form within it.
The test subject suddenly began struggling violently, as if he had sensed the fate awaiting him. His eyes widened to their limit, Fei Yun's cold face reflected in his black pupils.
The Soul-Cutting Technique activated. The seven-colored energy mass transformed into a streak of light and entered the test subject's forehead.
