After a tsunami hit your farming land, you're gonna see a lot of dense silt left behind. This thick layer really enriches the soil, and your crops will come out tasting extra thick and dense in flavor.

Know who’s likely responsible for this dense, thick layer of silt? Nostradamus (のう). He’s the one who urged you to buy this farmland in the first place, likely because he predicted the tsunami would bring this thick layer of silt.
