Apart from special items and methods, there were very few people in the world who could control Dragon Qi. Even the supervisors were powerless. Not to mention the tower spirit?
Therefore, Xu Qi 'an, who had the fragment of the book of the nether world, the pithy formula taught by the supervisor, and the luck of half the country, was the only one in the world who could control the Dragon Qi.
Under such a premise, Xu Qi 'an only had to be present when the Buddhist sect seized the Dragon Qi.
No one would have thought that there was an existence who could control Dragon Qi hidden among the martial artists of Leizhou. Jingxin did not expect it either. Therefore, when he learned that the tower spirit could guide Dragon Qi, he thought that he was almost certain.
