Zhou Bao was greatly relieved when his ninth acupoint was opened.
Feeling the purification of Internal Qi the same as before, he started to establish the circulation between the Real Dragon's Nine Acupoints. Finally, he understood the principle.
When the Real Dragon's Nine Acupoints were refined successfully, the nine acupoints would interact and influence each other, thus, forming a giant circulation. It looked like a huge Dantian, in which Internal Qi circulated smoothly.
What surprised him the most was that he could feel the enlargement of his Dantian clearly every time he opened his acupoints. When the ninth acupoint was opened, his Dantian would be the same as the other eight acupoints. The quantity of Internal Qi that they could store was the same.
What disappointed him was that after he had refined the Real Dragon's Nine Acupoints, he had not refined a real dragon successfully like he had done when he opened his first acupoint.
