The material in the hands of Wang Wei was called Deep Copper and it was a very rare Supreme Tier material used for refining magical weapons. The purpose of him having it is to actually blend the material into his skin.
The hardest part of cultivating the [Ancient Desolate Body Refining Scripture] is not the breathing method or the skin refining with wind blades. Although the special breathing method is hard to learn and it is quite painful to refine the skin with the power of winds, there were still myriads of people talented enough to finish these two steps.
However, the most difficult process was how to absorb the material into the body.
Wang Wei took a long breath and entered a deep state of meditation. He focused all of his mind and spirit into the Deep Copper.
Wang Wei did not know how long passed, but suddenly he felt a weird fluctuation from the Deep Copper. He became happy as he knew that he had finally found the Dao Breath of the Deep Copper.
