How to quickly get the gems in the buttoned space game "Micro Life"?

Gems can be obtained in some missions. I'm moving, and it's only three steps away I'm just doing the task of living and working in peace and contentment to get the jewels. You can buy more furniture and put it at home to improve the property of the house, and then you can get a reward if you reach the task index. It seems that there are gems in the reward.
