After Zhang Yan posed his question, Zhao Houzhou only hesitated briefly before deciding to reply truthfully. He bowed and said, "Daoist Zhang, my late master once discovered a Cave Mansion left behind by an ancient Immortal during his travels. Within, he obtained a Dao Skill. Seeing that the Dharma techniques recorded within were extraordinary, he abandoned the Dao techniques from our sect and began cultivating this new method. Now, the Dharma techniques cultivated by my three fellow disciples and I all originate from it."
