Feeling a wave of disbelief wash over him as he read through the first chapter of the First Four Mortal Realms describing the Qi Condensation Realm, Xuan Hao felt shocked at how in depth the chapter was.
Not only did it fully describe the process of going from the First to the Ninth Stage of the Qi Condensation Realm along with a lot of information about the realm that he didn't know anything about, but it also described a stage above the Ninth Stage of the Qi Condensation Realm. The Perfect Qi Condensation Realm, simply described as the Tenth Stage of the Qi Condensation Realm!
Even if none of his disciple's had reached this realm, Xuan Hao was still more than happy with the knowledge he gained from the first chapter of the ancient book, as it would be helpful for training his current disciples and future disciples.
