The boiler room seemed to be about 2 stories high, with a large and small boiler inside. The large boiler was almost two stories tall, and when approaching it, one could hear the roar of a steam engine. When the group rushed in, there was no one on the first floor.
"The big one should be 20 tons, and the small one probably a few tons. With this configuration, there should be at least a few people on duty. Why is there no one?" Qiao Zhen asked.
"The school wants to save money."
Yu Minglang noticed that there was a basement below. He exchanged glances with his brother, picked up the shovel next to him, and quietly went down.
Boiler rooms usually operate in three shifts, and it was currently the graveyard shift. As it was the beginning of the heating season and the demand for heat was not that strict, the school, wanting to save on costs, only needed one person for the graveyard shift. That person could very well be the criminal suspect.
