Jiang Yuan left Xie Wenyi and the others to Meng Chengbiao for on-site interrogation and took a few people to conduct a rough search of the second, third, and fourth floors themselves.
The many people going up and down likely compromised the scene somewhat, but at this moment, the most important thing isn't the scene inside the guesthouse.
No firearms were found as expected, but in the second-floor kitchen, Jiang Yuan found more mushrooms and small knives used for chopping mushrooms, among other items. Beyond that, some ground mushroom powder was clearly meant for steeping in tea and coffee, perhaps even for soups. Also, there were small chunks of pancake and grayish powder mixed in with the fruit jam and Lao Gan Ma chili sauce, which also appeared to be crushed mushrooms.
