Immortal martial arts..
Lu fan had never imagined the level of the world above high-level martial arts. Of course, he couldn't imagine it either.
In fact, Lu fan had come into contact with the ninth heaven and had made a judgment about the ninth heaven as a whole.
In Lu Fan's eyes, the immortal constellation realm wasn't immortal. The so-called immortal qi... was just the dilution of the chaotic power mixed with spiritual qi.
For example, the saint ancestor of the Saint clan used the power of the Heavenly Dao to temper his body and refine it into an incomparably powerful body. Perhaps, he even had the taste of an 'immortal'.
Therefore, in Lu Fan's eyes, perhaps... the saint ancestor was in a realm where he had touched the threshold of the immortal martial realm.
As for the ninth level of the Heavenly Emperor realm, perhaps he could have a say in the immortal martial realm.
