The first update!
After the top part of the glazed tiles shattered, the Fire Dragon Oil from the Western Region contained within flowed down entirely.
Whoosh!
This Western Region Fire Dragon Oil ignites upon contact with air, and in an instant, the entire cave was engulfed in flames, instantly incinerating the jewels and accompanying grave goods.
This is the typical tomb defense technique known as the Heavenly Dragon Fire Glazed Roof, a feature of ancient tombs. The tomb chamber was empty, and the ceiling was first lined with a thin layer of glazed tiles, above which bags of Western Region Fire Dragon Oil were placed. The slightest external force would shatter the glazed tiles, igniting the Fire Dragon Oil upon contact with air, and burn everything in the tomb chamber, including the bones and grave goods, leaving nothing for the tomb thieves but a fiery grave.
