KIKI, following Lin Xian's blueprint, designed a rough sketch of a water oxygen recycling system. Considering the issues of rainwater and health, Lin Xian planned to clear out carriage three, connect it to the locomotive's water tank, install a purification system, and set up some protective planting cabinets.
Clean water, clean air, planting green plants and vegetables—these were already part of Lin Xian's plans. After Xu Jin informed him that there was something wrong with the rainwater at night, Lin Xian became even more urgent about constructing such a carriage.
The arrival of ice and snow, bacteria in the black rain—all these would herald the extinction catastrophe for plants and animals worldwide.
In carriage two, the information center computer still glowed dimly. After being connected to the driving radar, photoelectric sighting system, and radar system, it could now guard a part of the area ahead of the train.
