Agricultural student Kang Zhiyong traveled through the magical world with half a bag of experimental grape seeds, and discovered that the magic here could corrode the land.
The nobles are addicted to magic and enjoy themselves, the land is depleting day by day, and the bottom class can only eat rye cakes that are unpalatable.
The vines he planted miraculously absorbed magical pollution, and the fruits they produced contained gentle energy.
The Holy Light Church is horrified: When grapes are turned into fine wine and spread across the continent, who needs to pray for magical healing?
An agricultural revolution using grapevines as weapons has quietly torn apart the world order that has been ruled by magic for thousands of years.
