After a string of disappointments in the city, he returns to his hometown when his girlfriend leaves him for money.
By chance, he gains a golden finger: an ancestral bronze gourd that opens a mysterious space.
The space contains spirit spring water of two grades. He can drink only three cups of the superior kind each day, but it can strengthen his physique, strength, agility, and intelligence.
Watering crops with the inferior spring water produces vegetables and fruits that are exceptionally sweet and crisp, far better than ordinary produce.
The livestock and river delicacies he raises are unbelievably delicious.
Eating them over time brings many benefits: minor ailments heal on their own, and even serious illnesses can be effectively eased.
The powerful and wealthy are soon clamoring to get their hands on them.
It's really well written, thank you
