Little Blacksmith of Tang Dynasty

Many people have traveled through time and can earn a lot of money, lead many soldiers, and marry many wives. But when Song Bo traveled through time, he just wanted to be a blacksmith. He didn't go to the court, but he had to nod his head or he wouldn't be able to pass the court matter. There's no fight, but if he doesn't nod, you can't win. Not out to sea, but without his nod you would just be a creature of the road. Who is he? He is the family patriarch who controls the economic lifeline of the empire. What do you want to ask him? The answer is that he is just a blacksmith who has served as a soldier. He just wrote the legend of the blacksmith.
