Marking the disaster drought

Bai Yun waited for a few hours as he waited for the main force to leave. He had to make sure that there would be some distance between him and the main force that left. Once he started to mess with the disaster drought, it might alarm them, so he needed some time before he started.

A day later Bai Yun slipped out from where he hid and carefully made his way to the few people still here. The cavern was an open space, but there was little light there. Along with the fact that they were meditating, none of them saw Bai Yun approaching.

When Bai Yun neared the group, he first stood behind them and then pulled out a pill, and broke it apart. The pill turned to dust and dispersed. 

The pill that Bai Yun just used was a simple pill that would dull people's senses and reactions. It slowly entered them through their nose and slowly started to dull them.
