As Pei Xuanjing's strength increased, naturally the speed at which he refined the Taoyun quickened.
However, even with that, it still took him two years to fully refine the Taoyun of the Ten Thousand Spirit Body Forging Skill.
At this moment, even though Pei Xuanjing hadn't cultivated this skill, he had a clear understanding of it.
This skill was indeed a demonic way, it was extremely domineering. It was about refining the essences of myriad spirit demonic beasts for self-use, and then using these essences to nourish oneself, forging the body.
This skill reminded Pei Xuanjing of the Beiming Divine Skill and the Big Dipper Method he had heard in his previous life. This skill shared some similarities with those two.
