In this chapter, we learn that the human race has been hiding in documents from the past dynasties. In fact, each time there has been a drought in the past, the government has been able to provide relief. The king has been going out to the border for long distance inspections to check on the status of the clan. This is because he has gotten poison from the black viper, which gives him the confidence to go out and fight foreign invaders. Now that we know that the four destinations of long distance inspection are actually the source of black viper poison, we can conclude that the extinction of the dynasty is the true cause of the drought.
