Tan Shuangshuang vaguely remembered someone in the family mentioning that there was a Wine Plum Tree in the Secret Realm, but at the time they were exploring the realm, everyone was busy searching for Ancient Spiritual Medicine and ignored the Wine Plum Tree.
Wine Plum is a low-grade Spirit Fruit, and although it is low-grade, it's quite expensive, the reason being its taste.
The taste of Wine Plum is sweet with a faint hint of wine, extremely delicious, having the fruit's savor without intoxication. Many cultivators are willing to spend a large sum to buy it.
Particularly those who love drinking favor it the most because it's said the wine flavor of Wine Plum is rich and aromatic. If one can brew wine with the Wine Plum, it becomes even more valuable, with a small jar the size of a fist selling for a sky-high price of a hundred Spiritual Pearls.
