His Primordial Spirit cultivation had not advanced because the evolution of his Inner World had not yet reached the level of a fully realized Primordial Wuji Grand Unity Golden Immortal.
Therefore, Deng Jiugong considered whether to use these two hundred million years to improve the Primordial World Tree or to advance his own Primordial Spirit cultivation.
