The Four Prime Cores!

Xia Fan followed the smell to the lobby. The strange odor was coming from a sealed medium-sized chest in the middle of the area.

Curiously, the center of the lobby should have been where the most people were concentrated, but on the contrary, there weren't many people there at all. It was probably because everyone thought that the valuable treasures were hidden in more secluded areas, rather than in such obvious places as this.

Alas, the chests were distributed randomly, and those putting the chests out had no idea what was inside them.

Xia Fan sniffed carefully. This scent was most likely that of an ancient kind of metal, neither the normal steel or trititanium alloy, nor was it the more valuable Keller Alloy. It was a special metal that Xia Fan had never encountered before.

In addition to the smell produced by the metal, there was a moldy scent produced from being stored in a place lacking airflow for a long time.
