Because the people on the mainland did not pay much attention to agricultural production, there were places that went out of production every year due to insect disasters, and many places starved to death. All of these left a deep impression on Grimm.
However, Grimm had to admit that the natural conditions on the ark continent were too good. They had a very high yield of white rice trees. These trees were like bamboo and could grow to more than ten meters tall. They could also produce rice twice a year, so most people on the continent would not starve to death.
The rice produced by the rice-producing tree was the most common food for the slaves. The tree did not require a lot of land. There were many places on the continent where it could be planted, so it was not easy for there to be a shortage of food on the continent.
