Jiang Xiaoxiao established the first experimental field.
It was set up at their exchange center, reportedly soil-less cultivation.
Jiang Xiaoxiao brought the latest soil-less cultivation methods from that world.
She can treat illnesses, but the nutritional deficiency is in vitamins and carbohydrates, which are found in fresh food, fruits, and vegetables, not achievable by medicine alone.
Jiang Xiaoxiao wanted to give it a try; cultivation is not impossible, but it needs seeds.
They don't have any, but we do.
We're not short of money.
No need for self-expenditure in exchanges; apart from not enjoying the treatment of a millionaire, this money can be reliably used to achieve many goals.
So, a steady stream of students under Jiang Xiaoxiao began researching soil-less cultivation techniques, and a large number of vegetables, fruits, and grains were produced within a few months.
The 900th floor is now living well.
The exchange center is crowded with people.
Everyone is joyous.
