To quickly clear traffic in various parts of A City, the current underground snow channels were constructed along the shortest routes and covering the widest areas possible.
As all residential complexes now had underground parking garages, it was only necessary to excavate the snow channels to the entrances of these garages to connect entire complexes. There was no need to dig all the way to the entrance of each building unit.
Tang Li’s complex was no different.
After entering the snow channel from the underground parking garage, Tang Li saw a row of lights installed on the ceiling of the passage.
On the wall next to each light, there were signs indicating the direction and distance to subway entrances.
Although the interval between each light was quite far, the reflection from the ice and snow was enough to illuminate a section of the passage.
The walls and ceiling of the passage were made of ice formed by splashing water.
At minus 25 degrees Celsius, ice became extremely hard, capable of withstanding bullets and artillery fire.
At the current temperature of minus 50 degrees Celsius, combined with sufficient thickness and reasonable design, using ice to support the underground snow channels was naturally feasible.
Arriving at the subway station entrance, Tang Li noticed many people coming and going, transporting excavated snow and melted water.
Although the passages from the subway station entrances to the underground parking garages of various areas had been cleared, this only allowed for the movement of people.
After all, vehicles could not enter the subway station, let alone the subway passages.
To restore cargo transportation in A City, the main ground roads connecting all areas had to be cleared; clearing only the subway entrances was insufficient.
It was precisely because the main ground roads had not yet been cleared that Tang Li now had to take a detour through the subway station to reach the supermarket, which would normally have taken only half an hour.
Upon entering the subway station, Tang Li felt a draft of air.
This was the subway’s ventilation system operating.
After deciding to use the subway to connect various parts of A City, the first action taken by the authorities was to dispatch personnel to clear the snow piled on the subway ventilation shafts and restore power to the subway.
Of course, only the lighting and ventilation power in the subway were restored; subway operations were not resumed.
Inside the subway station, Tang Li found clean containers placed everywhere, filled with piles of snow.
Due to the absence of industrial pollution and the fact that it had rained and snowed several times previously, the air was very clean. This snow, which had not touched the ground, was very pure and could be drunk directly after melting and boiling.
Every so often, a pile of burning coal could be seen.
Many of those involved in excavating the passages were gathered around the charcoal fires for warmth.
Iron pots were placed over the charcoal fires, constantly boiling snow water.
Some of it was boiled and ready to drink or use for heating.
Some, not yet boiled, was being loaded into buckets and transported away. This was the "building material" for the outer passages.
Once transported outside and applied to the newly cleared passages, it would form the walls and ceilings Tang Li had just seen in the passages.
To conserve electricity, not all the lights in the subway were turned on, making it somewhat dim.
However, at the subway entrances and within the subway station, security personnel were stationed to maintain order.
The entire underground world, this world beneath the snow, was orderly, with everyone busy with their tasks.
Besides those excavating tunnels and those on guard duty, there were also many individuals like Tang Li, venturing out alone.
Tang Li descended further into the subway station, soon reaching the platform.
It was an island platform with subway passages on both sides.
Tang Li saw that the doors on the subway passages had been manually opened, and on one side, people were transporting goods up and down.
Tang Li knew that this was the cargo route, specifically for transporting survival supplies to various parts of A City.
Since ground cargo transportation had not yet resumed, goods had to be transported via the subway routes and then carried to the surface, a process entirely reliant on manual labor.
Fortunately, with the subway tracks, one person could push several tons of goods.
In the subway passages, one could push carts along the tracks.
After unloading the goods at the subway station, they would be manually transported to the surface and then to the official material reserve warehouses.
This not only saved energy but also created more jobs, allowing many people to earn points.
The passenger line on the other side was similar.
By this time, many people were already queuing on that side.
Soon, a ticket seller arrived.
As this station was three kilometers away from the nearest station to Tang Guo’s home, Tang Li paid 0.3 points.
Shortly thereafter, someone arrived pushing a train car.
On this car, anything that could be removed had been, leaving only some seats and handrails.
Tang Li boarded the car with her ticket and found a seat.
After a moment, she felt the car being pushed forward.
