When Bai Yun reached terracotta hill, he realized the city was abuzz with the news of what happened in poison valley. He saw many people who were rushing towards poison valley. That included all kinds of people from adventurers to mercenaries and peddlers.
Bai Yun now had to find a place to recover. Bai Yun went back to the inn he had stayed in earlier and booked a room for a couple of days. Bai Yun then spend the next few days resting.
When Bai Yun finally left the inn a few days later, the situation in poison valley had died down. From the word on the streets, Bai Yun was able to gain a lot of news. He learned that the explosion this time was the largest in recorded history. Thus there were many many blue lotuses, and that even now new blue lotuses were coming up, though rarely.
