Lin Wanwan left many seeds in ancient times.
The hybrid rice, which doesn't preserve seeds well, wasn't chosen. Instead, she chose the optimized premium varieties, which are the favorites of organic farms due to their good taste. Although their yield is not as high as hybrid rice, it's much more substantial compared to the existing ancient grain varieties.
High-yield crops like potatoes, corn, and sweet potatoes were naturally left as seeds as well.
Fourteen hundred years later, Lion City boasts a wide array of fruits and vegetables. At present, many have either not been introduced and developed or are still in their wild, unmanaged state, not yet tamed by human hands.
The locals rely heavily on gathering food from the mountains, which isn't very stable.
Lin Wanwan must bring her people into an agrarian civilization. After all, this is her future backyard!
