In the game, the answer to the question "Can rice only grow in water?" is not absolute. The fact that most rice grows in shallow water does not mean that it can only grow in water.
Globally, about 13% of rice is grown in drylands. These rices are called upland rice or upland rice. These upland rice have been domesticated and evolved for a long time under dry land conditions without an aquifer, forming ecological crops that do not have high requirements for the growing environment.
To sum up, rice does not only grow in water, it can also grow in other environments such as dry land and shallow water environments. This is due to the growth characteristics of rice itself and the formation of ecological crops. Therefore, in the game, players can choose a place suitable for growing rice based on the specific environment and conditions.
