There was a small uninhabited island in the middle of the big sea. The next year the island was washed by the tsunami, a ship from a distant country visited here. And ancient ruins were discovered. "This is amazing! What advanced civilization is it?" An eminent archaeologist admired. It is said that there is evidence that progress has been made in a certain special field from the present age. The stone monument found was engraved with ancient letters. I could read it as follows. “Those who solve mysteries are omnipotent. So I don't even have to show mysteries.”
