In the story of the anime "Bad Guy", Li Xingyun is the first protagonist, and he is also the object of Yuan Tiangang's best efforts, and he is also a man sought after by beauties such as Ji Ruxue, the empress, and Chimeng. Since Lao Li is the protagonist, he is also destined to have advantages that others cannot have, especially the good luck of having immortal privileges and various adventures. Just after the broadcast of Season 6, Li Xingyun was forced to give up the Tiangang Technique, and then learned the Nine Shadows Xuantian Divine Skill, and later relied on it to fight against Mobei, Li Siyuan and other forces. In fact, this set of martial arts appeared as early as the first season, and the Hades Emperor and the Ghost King will do this kind of kung fu.
According to the plot of the anime "Bad People", the Nine Shadows Xuantian Divine Skill was originally a martial art invented by the Xuanming Sect executive, the Emperor of the Underworld, and one of the corpse ancestors, the Ghost King, the Emperor of the Underworld, Li Xingyun, and the Ministers 4 people all know this kind of kung fu. The Nine Shadows Xuantian Divine Skill is divided into two volumes, and only by learning the upper and lower complete works can it truly exert its power. It stands to reason that the Emperor of the Underworld and his vassals were the ones who invented it, so they should have a deep understanding of it beyond the comprehension of others. However, the Emperor of Hades was a little anxious for quick success, completely ignoring the power of it, and only learned half of it, and finally made himself a "weirdo".
Although the Ghost King didn't transform himself, he couldn't exert the maximum power of the Nine Shadows Heavenly Divine Skill. From this point of view, the Hades Emperor and the Ghost King are not the ones who can really learn it. As for the words of the ministers, in fact, she did not fully learn this kind of martial arts. In the plot of the 6th season of the anime "Bad People", the subordinate appeared, and she also saved Li Xingyun by changing her heart, and even taught the other party the Nine Shadows Xuantian Divine Skill. At first glance, Li Xingyun was taught by his subordinates, so the latter seems to have completely learned such kung fu. This is not the case.
In the plot of the anime "Bad Guy", the subordinate only introduced the origin of the Nine Mysteries Xuantian Divine Skill to Li Xingyun, and explained the main points at the same time, but the subordinate did not directly explain that she learned this kind of martial arts. In addition, the plot of Li Xingyun's abuse of Aunt Ao also explains everything. At that time, Lao Li took Ji Ruxue to the desert camp, and the subordinates gathered the four corpse ancestors to observe, and the object of their observation was Li Xingyun, whose intention was to "observe whether Lao Li can control the Nine Mysteries Heavenly Divine Skill". In other words, this time Lao Li learned the improved version, and the subordinate only experimented with him, and he did not take any risks.
Judging from that plot, the correct explanation should be like this: In the past, the Nine Shadows Xuantian Divine Skill had drawbacks, and the Emperor of the Underworld crippled himself without learning everything, and because of this, the subordinates improved it again, but she didn't dare to learn it herself, so she took Li Xingyun as an experiment. Because of this, the only person who has completely learned the improved version of the Nine Shadows Xuantian Divine Skill is Li Xingyun. This kind of martial arts will cause people's sanity, and Lao Li almost got hit, but fortunately, he overcame this drawback, and later directly abused Ao Gu. Such a situation is unthinkable even for the ministers.
From this point of view, the only person who can truly play the Nine Shadows Xuantian Divine Skill is Li Xingyun, which is something that even the subordinates can't do. I have to say that the anime "Bad Guy" still loves the protagonist more, otherwise Li Xingyun would not have been able to surpass the subordinates. But it's reasonable to think about it, because Li Xingyun can't use the Tiangang trick anymore, so if he doesn't set it like this, Lao Li won't be able to continue to hang up in the future.
