Getting rich starts with entering the game

Legend has it that there were four other civilizations on Earth besides us, Atlantis of the ocean civilization, Mesopotamia of the food civilization, Muria of the natural civilization, and the most mysterious Ghanda civilization.
"Casual Civilization" is a casual game with these four civilizations as the background.
Chu Lin suddenly gained the ability to enter this game, and also found that he could bring the prawns refreshed in the Atlantis map out of reality.
At first, he calculated that one pound of fine prawns was 60 yuan, and as long as the prawns refreshed every day were moved out of the game, he could earn 40,000 yuan a day.
Later, as the Atlantis map was upgraded, he found that he seemed to be able to cultivate prawns of quality beyond reality!
With the continuous opening of the four civilization maps, things that surpassed the quality of reality appeared one after another, and everything was different!
