"But what exactly does 'marrow cleansing' refer to?" Li Chenggong asked.

Xu Hao smiled and said, "Hair Cutting and Marrow Cleansing is like combing out the impurities of the human body, making the body as pure as a newborn without any impurities. However, I don't quite understand the specifics myself."

At this time, Li Lingniu suddenly said, "But you've talked so much and still haven't said how it could prolong my father's life!"

Xu Hao hesitated for a moment, then said, "I don't mean to hide it from you all, but I truly haven't learned the Defying Heaven Nine Needles yet, because I'm not strong enough. To learn the Defying Heaven Nine Needles, one must have already undergone Hair Cutting and Marrow Cleansing. And completing Hair Cutting and Marrow Cleansing means that one's strength has reached the Martial Sovereign level, and I'm still far from reaching the Martial Sovereign level!"
