Inspired by this.
He quickly formed a plan for washing and refining the spiritual energy of his two sons.
In just ten days, he had a complete plan.
By this point, the "Innate Dao Body" creation plan was more than half complete.
So on a lucky day, taking advantage of the good weather, Lu Yuan brought his eldest son, Lu He, to the same Bifang Garden where he had helped Sun Siwen refine his body and soul last time, and began to help him with spiritual energy refinement.
With the experience from last time and months of research, the "Innate Dao Body" was completed in just five days, without much effort.
It even took two more days than last time, mainly because Lu He was only a child, with far less powerful mental and spiritual strength than Sun Siwen. As a result, Lu Yuan had to put in more energy and control everything 100%.
Nevertheless, Lu He's success demonstrated the feasibility of the "Innate Dao Body" plan.
