1, the upgrade switch of the last two plots is at the entrance of Shuangfeng Harvest. Click on the top right corner, and you can see it by doubling the harvest.

As you can see here, there are three options to unlock the eighth and ninth plots.

3. One is to buy gold coins, and spend 1500 gold coins to buy the right to use for 7 days. After the date, the land use right will be lost.

4. 14 days is valid, and you need to make a single purchase, that is, you can use the land by making a single page 14 days.

5. Check the seeds and calculate the income. According to the maximum value of 200 a day, the income for 7 days is 1400 gold coins. It's less than 1500 gold coins we spent 100 gold coins. In other words, if it is unlocked normally, the income will be negative, so it is meaningless to spend gold coins to unlock the land.

6. To sum up, if you unlock these two plots with gold coins, you need to combine one thing, that is, upgrade all the plots to golden land with three times the income. In this way, the income of these two plots has tripled, and there will be no loss.
