After stepping into the realm of "Spiritual Light First Illumination," he needed to absorb the golden fire poisonous qi from the earth's veins to refine his Xuan Guang. Only by further enhancing and purifying the Xuan Guang could he achieve the Second Realm, "Day-like Night."
He walked out of the cave mansion, and with a single step, a clear cloud rose from the ground and gently carried him to the mountain summit, where he landed at the fire mouth.
Before proceeding, he glanced downward, seeing the surrounding black clouds blocking out the sun, smoke and dust suffusing the air and stifling the senses. If a normal person stood here, they would suffocate within seconds. Yet, Zhang Yan felt no discomfort; on the contrary, the golden and fiery Xuan Seeds within him became increasingly active and lively compared to usual.
