Jing Yan took a total of six years to master the third layer of the Great Demon Seal Suppression Technique.
The Netherworld Crystal Stone was thoroughly consumed, with four pieces used by Jing Yan, leaving only one pale yellow crystal stone remaining.
So far, Jing Yan has mastered the Power of the first three layers of the Great Demon Seal Suppression Technique. This spell only has five layers in total, and Jing Yan has yet to obtain the materials needed to cultivate the fourth and fifth layers. To continue his cultivation, he must find a way to purchase the necessary resource materials himself.
"These Netherworld Crystal Stones are truly useful, but unfortunately, they are too scarce. I wonder if I can buy some more from Lord Wuxia." Jing Yan contemplated silently.
