"Church’s year 797, the 8th day of the 2nd month. It was the fourth day since I stayed at the Grizzly Fortress. Today, I am finally able to get to know of the secret testing ground of the Sukhoi family. It’s no wonder why there is no furnace and ironwork factory at the Grizzly Fortress. It’s because the people of Sukhoi had emptied that dead volcano behind the fortress in a period of two centuries. The blacksmiths of this family utilized the fiery underground lava in the mountains to melt metal and produce all sorts of excellent weapons. Of course, after two hundred years, this is no secret to the spies in every country. It’s only that I just knew about it."
