It was common for humans to defecate.
The three men did not find it strange. The one with the sword let one of the men with a knife accompany Doctor Shen downstairs to the toilet at the back.
There was a small toilet behind the inn. The person carrying the knife strode in first to see if there was anyone inside. There was only a lamp hanging from the beam to show that it was the toilet. Seeing that there was no one, he strode out again and let Doctor Shen, who was standing at the door of the toilet, enter.
It was also at this time that Jiang Yue, who had already entered the toilet and entered the space, came out. Therefore, when Doctor Shen came in, he saw Jiang Yue waiting for him.
Doctor Shen was greatly surprised and felt that Jiang Yue had hidden herself very well. That person had already come in to take a look but had not discovered her.
