Many people can make a lot of money, bring a lot of soldiers, and marry many wives. But Song Bo just wants to be a blacksmith after time travel. He didn't go to the court, but he had to nod his head or he would not pass the court. No war, but he doesn't nod, you can't win. No sea, but no nod from him, you can only be a road creature. What do you ask him? The answer is, he only knows about blacksmiths. He just wrote the legend of the blacksmith.
