Inside the Heavenly Fire Mountain Range, Guo Yurong stared at Xiao Changtian, waiting for his answer.
"Squeak squeak squeak!"
At this time, the Divine Monkey was standing on Xiao Changtian's shoulder, squeaking.
"Little girl, Master is currently tempering his heart in the mortal world. You'd better not mention cultivation in front of him."
The voice of the divine monkey slowly sounded in Guo Yurong's mind. Guo Yurong also understood.
Cultivating one's heart in the mortal world. He did not expect that there was really such a cultivation method.
Guo Yurong had read about it in some ancient books.
The description of it was probably after some supreme experts cultivated to a certain realm.
When they encountered a bottleneck and wanted to break through to a higher cultivation, they chose to go to the lower realm to cultivate their minds.
However, it was also a huge test for cultivators.
