The batch of wine jars unearthed from Nuwa's tomb, upon appraisal, should be ten thousand years old. Their patterns and sizes are exactly the same, and they are all completely empty.
Considering the surrounding settings, it seems as though someone drank all the wine when entering the tomb, not stopping until completely intoxicated.
Thus, ten thousand years later, only a pile of toppled empty jars remains.
This actually runs contrary to archaeological experience. In a real burial site, the wine jars wouldn't be empty without reason. Rather, as Zuzi said, this is the Fu Xi Palace, which aligns more accurately with the origin of the wine jars — Fu Xi feasting in the palace, drinking all the wine.
Feng Tang was obsessively studying the wine jars that Zuzi "reimbursed" him with when suddenly, a casual discovery made him leap excitedly from his seat in shock—
"This wine jar, this wine jar has... real wine!"
