Product description ※Please note that product information is not in full comprehensive meaning because of the machine translation.

Ten years ago, after a meteorite came close suddenly, the dungeon was created as if it had "fallen and sprung". The magic crystal mined there completely changed the world's energy situation. Electricity rates became cheaper and it was eco-friendly because it did not emit carbon dioxide. The people who mined the magic crystal were called "Minor". Because high-concentration magic crystal was bought at an extremely high price, there were many Minor and dungeons dreaming of getting rich at once. There were even people who woke up to something called "Unique", but because it can only be used in dungeons, the world became peaceful and prosperous. Yes, it was ten years since then. "This is a great world." A dungeon quietly stood in the backyard of a used house I bought that had not been used for years. "How much would it be if I converted all into money?" There was an untouched pile of high-concentration magic crystal there. This is a story about how I sell the magic crystal in "Backyard Dungeons" quietly and without anyone knowing it. The goal is "an annual income of 12,000,000,000 yen." Thanks to that stupid but desperate goal -- I was able to recover from the bottom.
