Shen Siyuan took out the copper mirror he had found earlier in the Yangzhou Netherworld Ruins.
"Copper mirror?"
Wu Yugu caught a glimpse of the ancient bronze contour, and a trace of barely noticeable disappointment flashed through his eyes.
In his view, copper mirrors like these are abundant, not truly rare treasures.
From the seven-pointed star pattern mirrors of the Neolithic Era Qijia culture, to the pinnacle of Han Dynasty technological craftsmanship in translucent mirrors, and the lavishly decorated Tang Dynasty sea beast grape mirrors witnessing cultural fusion, he had seen and touched such treasures firsthand.
But these artifacts are primarily decorative, with very few inscriptions surviving, offering limited research value to someone specializing in ancient scripts like him.
Yet in the next moment, Shen Siyuan's fingers gently turned the copper mirror over, revealing the patterns on the back.
"Hmm?"
