At the moment, Drunk's team had been deep into the Carrion Swamp, around a few hundred miles away from the border. Continuing to go deeper looks quite difficult, thus they prepared deliver what they had accumulated first.
Zhao agreed to Drunk's decision. Compared to the threats of the Purcell clan, the Carrion Swamp poses a lot more danger. After all, even if the Purcell clan attack them, they could hide in the space. This was not the case with the threat of the Carrion Swamp.
If they wanted to live in the Black Wastes for generations to come, they should solve the problem posed by the Carrion Swamp.
Because of these thoughts, Zhao was now very anxious, ordering Drunk to go continue observing. Getting more information about the Carrion Swamp was the most important.
