The first fruits were given priority to the king, who loved to eat grapes, but couldn't eat so many at once.

After tasting it, the king also felt that it was a delicious delicacy on earth, so she became particularly fond of this princess and the "poison". After obtaining the favor of the magistrate, the king issued a decree to collect a large number of ripe grapes and make delicious beverages using the method of "poison"
