After Feng Qianye explained the key to breaking through to the Nascent Soul Realm, Su Hao had the entire breakthrough process figured out.
For him, the hardest part was still cultivating "Spirit Sense." With his prior experience cultivating Spiritual Intent, Su Hao had originally thought that cultivating Spirit Sense would take at least a year or two of sitting in meditation. He had even prepared himself mentally for it.
Unexpectedly, the cultivation of "Spirit Sense" was finished in twenty days. To be honest, that had exceeded Su Hao's expectations.
The next step, cultivating the Spirit Method, was much simpler.

In other words, the physical body had to gradually transform into a Spirit Body.
The proportion of spirit flesh within the body would slowly increase with cultivation time. Once it reached around thirty percent, the physical body would undergo a transformation. At that point, one would successfully break through to the Nascent Soul Realm.
The key to that transformation was time.

Instead, one had to follow the body's metabolism. As the body exchanged substances, spiritual power would gradually replace part of the tissues step by step, completing the permeation.
That was to say, with the help of Spirit Sense, which was in sync with the mind, this process was not difficult. One only needed to follow the
