The boiler room looked about two stories high, with a large and a small boiler platform inside. The larger one was almost two stories high, and as you approached, you could hear the roaring sound of a steam train. When the group rushed in, the first floor was empty.
"The big one should be 20 tons, the small one estimated to be a few tons. With this setup, at least a few people should be on duty, why is there no one?" Qiao Zhen asked.
"The school wants to save money."
Yu Minglang saw there was another basement level below. He exchanged a glance with his brother, picked up the shovel placed on the side, and silently went down.
Boiler rooms usually operate on three shifts. Currently, it's the understaffed night shift. It's the early heating period, and the heating requirements aren't as strict, so the school saves costs by having only one person on the night shift. That person is probably the crime suspect.
