Capítulo 371: The Black-Line Star Listing

Three faceted blue crystals lay quietly at the bottom of the spring, which was where the intense energy fluctuations were coming from. Chen Mu carefully picked them out of the hot spring and looked at them closely. They had a standard faceted shape and were completely free of impurities, like pure sapphire. The biggest was about the size of a fingernail, and the smallest was the size of a soybean.

But it was those little bits of crystal that had been disseminating such intense energy fluctuations. He could only imagine what level of energy density they contained!

The three blue crystals weren't among the materials Chen Mu was familiar with. Even so, he knew he had found a treasure. Materials that could be used to make cards had the common characteristic that they had to be compatible with energy. The three crystals contained a terrifying amount of energy and must have had an outrageous energy compatibility.
