Han Zheng took about three months to complete his closed-door training this time.
Using the Taotie Furnace to enhance his realm is quick, but the Primordial Essence requires a long period of continuous immersion and insight. Han Zheng's spirit was deeply engrossed, often taking more than ten days for just one insight.
When Han Zheng came out, he found that Yan Xuankong had not yet finished his retreat.
After inquiring with Chen Baxian, he learned that Yan Xuankong had made a new discovery in the application of Incense Fire Divine Power. He wanted to enter the Dao through this power, and if successful, he might even reach the Dharma Manifestation Realm.
Han Zheng couldn't help but admire, despite Yan Xuankong's questionable moral character, he is indeed an extraordinarily talented genius in Martial Arts.
If his path had not gone awry back then, he might already be a Commander in the Dharma Manifestation Realm now.
