Ning Que was quiet because he was disappointed and angry. Sangsang had always been quiet. She became more quiet because ever since they left the dwelling of the savages, there was nothing but vast wilderness along their way. They were getting further away from human habitation and further away from the human world, although in different ways.
They crossed the Wilderness via the same route they used to take. When summer came, the black carriage arrived at the Morass. They sensed the smell of rot and damp and saw the fog. If it was in the past, then Ning Que would have been worried about the invisible dangers hidden in the marsh and fog. However, he couldn't care less now because he knew that Haotian was right here in the carriage. It was also because he knew who the master of the Morass was.
