You start growing thread in your rice paddy to accumulate more. You didn't want to have to buy any, so you're just trying to grow thread with your rice. That seems like a good way to accumulate more to you.

Sadly, this is a terrible way to accumulate anything thread related and you ended up ruining (るい) your rice paddy too. I guess if you want to accumulate thread this isn't the way to do it.
