Inside the Cold Cave.
Ling Fei drew a large amount of Cold Qi into his body.
This Cold Qi was very pure. As soon as his spine absorbed it, Cold Chi Dragon Qi was fed back to Ling Fei.
This allowed Ling Fei's cultivation to continue without interruption.
A continuous stream of Cold Qi was absorbed by his spine, which in turn fed Cold Chi Dragon Qi back to Ling Fei.
This formed a virtuous cycle.
As a result, the flow of Cold Chi Dragon Qi within Ling Fei's body never ceased.
Subsequently, the Cold Chi True Qi inside him was continuously generated.
'With the Cold Qi Primordial Vein providing such pure Cold Qi, my cultivation speed is truly fast!' Ling Fei felt a surge of excitement.
His cultivation speed here was a hundred times faster than in a place with ordinary Cold Qi.
This gave him hope of reaching Ninth Layer Body Tempering Perfection and breaking through to the Innate Realm.
This was the difference a Primordial Vein made.
Cold Qi was just Cold Qi.
