Yan Rufeng calculated the time, and there were less than ten days left before the contest between the two major bases. He couldn't continue his secluded cultivation. One Nascent Soul had taken him over two months, and cultivating another would take even longer. Yan Rufeng looked at the numerous Spirit Veins within Southern Yue, shook his head reluctantly, and left Southern Yue on his Flying Sword.
Ordinary cultivators who reached the Nascent Soul Stage had only one Nascent Soul in their Dantian, but Yan Rufeng was different. To advance to the Emergence Stage, Yan Rufeng needed twelve Nascent Souls. This could be seen from when he was in the Golden Core Stage, where he had twelve Golden Cores to reach the Nascent Soul Stage.
Therefore, no matter the level, Yan Rufeng's cultivation always required twelve times, or even more, the Spiritual Energy and time of an ordinary person.
