The advancement of the boiler modification in the shelter, which concerns the survival of all survivors within the shelter, progressed rapidly. Although Chen Xin required many materials, fortunately, the underground highways between various shelters remained open. After spending some time gathering them, the materials he needed had already been transported to the police station's shelter.
"Comrade Chen Xin, the materials you needed have arrived. When do you think you can start the boiler modification?" The commissar found Chen Xin who was eating in Qin Lan's room. Although he felt a bit embarrassed to interrupt Chen Xin's meal, he couldn't help but impatiently ask Chen Xin.
During the time Chen Xin was eating, the temperature in the special police team area had increased thanks to Chen Xin upgrading the geothermic heat pump and heating. The temperature rose from the original minus ten degrees to about seven or eight degrees and was still rising, with hopes of breaking zero.
