After Zhou Yun returned to his cave abode, he let Su Lingyun settle down in an empty room and then continued his cultivation.
The vessels would open by themselves when the Qi was full. With the support of the enlightenment during the foundation establishment, Zhou Yun did not directly engrave the elder's foundation establishment method on his mind. Instead, he combined the Spiritual Qi Mantra with the foundation establishment.
Now that his meridians had completely opened, his cultivation was twice as effective with half the effort. Just as he returned to his cave abode, Zhou Yun tried circulating the Spirit Qi Mantra while walking.
He realized that with just a slight distraction, the Spiritual Qi Mantra would automatically circulate like breathing!
Unless his emotions fluctuated too much or he interrupted it himself, the Spiritual Qi Mantra would continue to absorb the spiritual Qi of heaven and earth to increase his cultivation!
