As soon as Angel grabbed the gemstone cover, he felt a surge of elemental energy.
After careful examination, Angel could confirm that the elemental aura came from the ruby and sapphire on the lid.
The ruby and sapphire emitted elements related to fire and water, respectively, but they were both composite elements and not pure.
From this, it could be determined that the ruby and sapphire were artificially processed elemental gemstones.
However, the method of processing and the materials used, even with the Alchemy Eye activated, Angel had no way to determine.
Similarly, Angel could not determine the material used to create the metal cover.
The main reason is: lack of information.
Although the materials of the ruby and sapphire could not be identified, judging by the perception of elements and the nature of the remaining energy inside the metal cover, the rank of these materials would not be too high.
