Return.

Hao Ren and Han Lingshi both were cultivating and having the undisturbed time with each other. They came to understand many secrets of the cultivation together. One of the biggest secret was the fact that spiritual energy was similar to nature. 

This helped them master the movement technique, Cloud Breeze Steps to the minor success realm. The couple then moved on to practice fist techniques and sword techniques. Although they did not have any guidance, they both were able to analyze things on their own and help each other progress slowly. 

They did not expect themselves to grow into some over powering existence. However, some basic practice would allow them to save some time when they return home.
