As a senior appraiser of strange stones, Lin Chen could tell at a glance that one of the gray-black stones was something special—the surface was rough, but it had a warm luster and strange texture, and was definitely not an ordinary pebble. He struggled to get out of bed and picked it up. His hands were cool and delicate, heavier than ordinary stones, and the sound of knocking was dull and thick. He was sure that this was a strange stone that could be sold for money.
