He finally smiled: "You've done your homework well." His long fingers pointed at her pocket: "Tell me about the pearl in your pocket."
Shi Nian secretly gritted her teeth...
Once again, he figured it out.
She can understand the method now; it's because when he mentioned pearls earlier, she instinctively reached to press her pocket to ensure the small, rice-sized pearl was still safely stored there.
Shi Nian took another breath: "Based on all this, I paid special attention to the patina and surface color of this pearl, deducing from the degradation of its pearly layer that it is already an 'old one.'
Shi Nian said while taking out the pearl, and Tang Yanqing tacitly picked up a magnifying glass.
Both of them leaned in to closely inspect the pearl. Shi Nian pointed at the drill hole: "The edge around the drill hole is the most fragile part of the pearl. It's already somewhat brittle here; it's the beginning of dry decay. So, I guess this pearl is about a hundred years old."
