After the Black and White Impermanences cultivated the Nine Nether Mysterious Heaven Divine Art, their abilities had improved. The Nine Nether Mysterious Heaven Divine Art was a kind of cold cultivation technique that countered the bad marshal's Big Dipper Technique.

The Black and White Ghosts 'Nine Nether Mysterious Heaven Divine Art had increased their strength, allowing them to fight against powerful opponents. However, the true power of the Nine Nether Mysterious Heaven Technique had yet to be fully displayed. It required further practice and mastery.

The Nine Nether Mysterious Heaven Divine Art came from the series of "Painting the Unscrupulous People of Jianghu". It was the most powerful divine art of the Xuanming Sect. Written by Underworld Emperor Zhu Yougui and Corpse Ancestor, it was divided into the first volume, Nine Serenities, and the second volume, Profound Heaven. The power level of this skill was around that of a greater celestial. It was a top divine skill in the world, extremely yin and evil. Only Ou Yezi's Dragon Spring Sword Art could restrain it, but it could also be restrained by the Seven Stars Art. This cultivation technique required both the upper and lower levels to cultivate. If one cultivated only one volume, the lighter the case, one would not be able to reach the highest realm. The more serious the case, one would go berserk and become neither human nor ghost. The Underworld Emperor skipping the first volume to cultivate the second volume was an example. To cultivate this technique, one must have hatred in their heart, kill decisively, nourish their body with killing intent, circulate qi with their mind, and circulate qi according to specific meridians and acupoints. The Corpse Ancestor General Minister has released the second volume of the Nine Nether Mysterious Heaven Divine Art (new version) and handed it to Li Xingyun to cultivate. There are still side effects, and the second volume may need to be modified. The Underworld Emperor and Ghost King Zhu Youwen had become greater celestial experts through cultivating this art. They were extremely powerful, but they had only cultivated the second chapter back then. Judging from the situation of the Black and White Impermanences who cultivated the upper and lower scrolls, the Black Impermanence had a backlash, but the White Impermanence did not. Perhaps the side effects of the male full cultivation were greater.

The Nine Serenities Mysterious Heaven Divine Art came from the series of "Painting the Bad People of the Jianghu". It was the most powerful divine art of the Xuanming Sect. It was jointly written by the Underworld Emperor Zhu Yougui and the Corpse Ancestor. It was divided into two volumes. The first volume was "Nine Serenities" and the second volume was "Mysterious Heaven." The power level of this art was around greater celestial level, and it required both upper and lower cultivation states. If one only cultivated one volume, one would not be able to reach the highest level in the least, and in the worst case, one would go berserk. For example, if the Underworld Emperor skipped the first volume and cultivated the second volume, he would become a dwarf. At the age of 30, he had the appearance of a child and was ugly. The Ghost King was a genius in martial arts. Even if he made a mistake in his cultivation (only the second chapter), he could still master it without any side effects. The Black and White Ghosts were the same (the specific reason might be that their bodies were very heavy with Corpse Qi). Judging from the cultivation technique's Qi deviation and rejuvenation, Ying Gou's cultivation technique might be the source of the Nine Nether Mysterious Heaven Divine Art, and it might be a branch of Ying Gou's cultivation technique. This skill was extremely evil and was a top martial art in the world. The Yin poison contained in it would repel the Yang qi of men and cause a backlash (this may also be the reason why the side effects of men's full cultivation were greater, such as the backlash of Black Impermanence but not White Impermanence). It could be restrained by the Seven Stars Formula. The Corpse Ancestor General Minister released the second volume of the Nine Nether Mysterious Heaven Divine Art (new version) and gave it to Li Xingyun to practice. It still had side effects. The pithy formula of the cultivation method is as follows: There is a mysterious sky in the nine netherworld, and there is a mysterious sky in the upper and nine netherworld in the lower. There is no need to be restrained and the same, so that life and death are obvious. It can absorb yin and half of the soul, so that there is no phase and no Shang. Black and white will never change, and the sea of qi will hang in the mourning hall.
