Finally, by the way, there is also a gift-giving activity for friends. The 45-level crop malachite grass basically defeated the red soil seed agropyron cristatum. This seed is a five-season crop, the first ripening time is 29 hours, and the subsequent time is 12 hours. At present, it is a perfect seed, and its profit is similar to that of agropyron cristatum.
To sum up, if you are not a professional farm player with a large number of trumpets as the back garden, it is suggested to plant the highest-grade crops on black land, wheatgrass on red land and malachite grass on ordinary land.
The information is so comprehensive that the landlord gives points. In addition, if you need a list of seed attributes, I can also give it to you. There is too much content here to type by hand. Very tired.
