695 True Nine Words Seals

Xu Zhiling practiced a lot of martial arts and used a wide variety of them. This was something that was rather similar to Happy, but the ultimate techniques Happy required to take action were different from Xu Zhiling's rather unique martials arts. 

The first one was Immortality Art, but he also practiced Fu Junchuo's Nine Great Abyss Arts, which was a qi cultivation technique. Later on, he obtained Evil Emperor Obtains Wealth. With the ability he acquired from Gobi Desert, he created a strange and unique Three-in-one Origins Qigong. It was something that no one in the world could replicate or practice. 

Even his successor might not be able to inherit that technique. 

Happy explained that if he wanted to deceive the world, he had to practice at least one of Xu Zhiling's martial arts, and his Nine Yang Divine Skill could coincidentally help him do just that. Once he saw something once, he would not forget and could also quickly copy it.
