Help mom to play QQ farm

Today, I played my mom's QQ farm. Mom applied for two QQ. Because my mother's farm upgrade was too slow, I thought of a way.

I opened another farm to lay grass and insects, and then I removed the grass from myself. Deworming. This way I can earn a lot of points. My mother has expanded 12 farmland, and only 3 grasses and 3 worms can be placed on each field. 2 grasses and 1 worm can be used to earn 2 points each. So how many points can each earned in each field? 3 grass plus 3 insects equals 6, and each plot 6 times 2 equals 12 points. Wow! I earned 12 points in a field. 12 Fast Field has a total of "12 times 12 = 144 points", so the farm upgrade is even faster.

Watching the worms twist and twist on the seedlings, and then remove them themselves, they earned points and played games, and my mother praised me for being "smart." Don't mention how happy I am!
