'Innate Qi!'
Though the Qi mechanism was initiated by Tianxuan, it seemed as if it originated from Jiang Li himself. Since Tianxuan already holds an advantage in certain aspects, and with the Qi mechanism now mimicking Jiang Li perfectly, it naturally attracts the Yinglong Dao Fruit more than Jiang Li himself.
So the question arises, how did Tianxuan come to possess Innate Qi, and how is she able to imitate Jiang Li's Qi mechanism so closely that there is no discernible difference?
The Jiang family's "Qi Tomb" was created by Emperor Yan using his own Divine Farmer's appearance as the foundation, making it an exclusive magic door of the Divine Farmer's appearance. This means that those who could cultivate "Qi Tomb" either have similar characteristics or possess the bloodline of Emperor Yan.
Outsiders can't comprehend the "Qi Tomb" magic door without a high realm to modify it, otherwise it's difficult to grasp its essence.
