Having come to the decision to go back in the same direction she had essentially come from and make her way back into the deeper regions of the ancient city despite the danger involved in doing so, Mui made sure to keep an eye on her surroundings. Keeping an eye out for any fog that might be approaching her, as she understood that fog appearing was a bad thing and a sign that the golems wandering the ancient ruins were getting closer.
Outside of just watching out for the ancient golems that wandered around the ancient city, she also kept an eye out for any of the demon beasts that had managed to stay alive up to this point in time.
The reason for doing this was not because of some kind of practical reason, but more so because she found it enjoyable to spend time with the different demon beasts wandering around the ancient city similarly looking for a way out of the place like she was.
