The chairman of the Mining Union of Gold-Panning Town was so fat that he looked pregnant. He was swaggering down the road to visit the town, and he was accompanied by the deputy mayor of Pyroxene Town.
He came to gain some experience to try to apply it to Gold-Panning Town.
In other words, he actually had the same "job" as Wood, but Wood secretly sneaked in, stealing the information while he visited, learning it directly.
In fact, if Wood also made a direct visit, the officials of Pyroxene Town would be very happy to receive him, offering food, accommodation, and accompanists. Except for some secrets, they would explain most of the things to him in detail.
However, Wood made a mistake. He subconsciously believed that the information was very precious, and Pyroxene Town would certainly protect the experience as top secrets. Without some special means, he absolutely wouldn't be able to get the information he wanted.
