Kapitel 612: Harmony.

Yang Dao and Dao Yin were sitting in their cottage, they were immersed in cultivation. A few days ago the two had come back from dealing with the incident in the Shelter Celestial Empire, and they asked Laohu Bai for something. 

The lady was unable to deny anything to the two of them so she put forward a condition. The condition was that the two people stepped into the second stage of immortal cultivation. This required the couple to have the organs of their body to be tempered to the level of immortality. 

The process was a little different than what they did in the first round of the immortal cultivation. The second stage needed them to blend their cells with the spiritual energy. When the person is united with the spiritual energy, that is when they become immortal. That was something she had told the two people earlier.
