Nirvana Technique, Nirvana Sutra, Nirvana Technique…All three of them had been cultivated to the perfection of the sixth level by Zhu Wanwan. Moreover, there was a way to break through the Heaven Pillar in the books on the sixth level.
However, once he cultivated to the level of the Form One Heavenly Pillar, there would be no more cultivation techniques for Zhu Wuyang to cultivate. He would have to obtain the Nirvana Scripture and the seventh level of the Nirvana Technique to continue cultivating. Naturally, it was the same for the Nirvana Technique.
However, if one wanted to obtain the lower part of the Nirvana Ceremony, they had to go to the Nirvana Tower's headquarters. There were no jade slips related to it.
