That night.
Tang Yue lay in bed, clinging tightly to his blanket with only his head peeking out. The rotation of the fan blades produced a soft hum that sounded like a mosquito. The temperature in the living quarters was maintained at 20°C, but the temperature outside had already dropped to –60°C.
There was a pale yellow light seeping in through the gap of the curtains. Tomcat wasn't resting yet. It was still making preparations and packing for tomorrow's expedition. Tang Yue listened to the familiar noises. Tomcat was rolling up maps. With the Mars Wanderer heavily damaged, it didn't have a single intact monitor. They had no choice but to use paper maps.
