After crossing the border between Kazakhstan and Lucia, which was deserted even before the disaster, Chen Xin's train arrived at the planned station on the border.

However, just as expected, they encountered the problem of changing tracks. Not only that, the so-called station had already been completely buried by snow. To complete the operation, they had to clear out two rails of different widths. Not to mention, they also had to remove the cranes, warehouses with wide gauge wheels and platforms used for the operation from the snow Dig it out.

Fortunately, this is nothing for Chen Xin. He instructs the soldiers on the train to help clean up the two tracks. After finding the wide gauge wheels, he asks them to build a temporary gate between the two tracks with an engineering vehicle.

Then Chen Xin let their train through the gate to the wide track, and directly upgraded their train with the wide track wheels found by the soldiers.

With the upgrading of Chen Xin's order, the spacing between the wheels of the train was widened to a suitable width, which quickly solved the problem of changing tracks. It was not necessary for soldiers to dig out the crane on one side, and then spend several hours to lift the carriage onto the wide rail road.

And after that, they moved on again.

Only after entering Lucia, the road is not as smooth as in the territory of Yan and Kazak.

The thick snow all over Siberia, together with the disaster caused by the impact of meteorites and the lack of maintenance after the disaster, made a lot of railway tracks here damaged, which made Chen Xin often need to walk for a period of repair. They wasted a lot of energy to get through the vast snow and reach their destination.

This is a typical no man's land deep in the great forest of Siberia. Before the disaster, there was no road leading here except a secret military railway which could lead to the secret military base deep in the forest.

In order to isolate the unexpected situation, some people inadvertently set foot in it and discover the secrets kept by suvia.

Before it was sealed up, the suvians built a small town here to serve the soldiers and scientists in the military base. The town has a series of living facilities such as stations, schools, hospitals and so on, ensuring that the soldiers and scientists living here can get all the life needs in the small town.

However, with the sealing up of the military base, all the soldiers, scientists and staff who once lived in the small town have been evacuated, and the small town, together with the sealed military base, has been sealed up in the depths of the Siberian forest.

If it is before the disaster, the scenery here is quite beautiful.

With a clear suvian era of various small town buildings, surrounded by lush virgin forest covered with rolling mountains, there is a beautiful lake beside.

It can be said that in the Cold War era, life here was extremely comfortable without the threat of war and the noise of big cities.

Of course, there may be less recreational activities. However, there were not many recreational activities in that era. It was not a big problem that life was simpler.

Now, however, everything here has been covered with thick snow, almost no trace of human life can be seen.

"According to the information given by Lucia, our current location should be the railway station, which is located in the west of the town. In the center of the town is an office building, where there is an underpass leading to the military base. We can go through the underpass connecting the office building from below the railway station." The officer opened the town map provided by the lucians, pointed to the names marked in Russian on the map and explained to Chen Xin.

Chen Xin took a look at the map and found that he could not understand the Russian language on it. He did not pay attention to the map any more. He just said to the officer, "since you are in charge of the operation command, you can make up your mind, but be careful. It's hard to guarantee that there were no defensive measures left when the Soviet Union withdrew."

"Please don't worry. We've brought special explosive disposal engineers this time. There won't be any problem." The officer nodded solemnly, which he also took into account, so he not only brought the EOD engineers, but also made them wear the heavy EOD mecha specially developed by the military.

When Chen Xin saw two engineers appear in EOD mecha, he couldn't help picking his eyebrows and asked in surprise, "is this the heavy mecha I designed?"

"Yes, after analyzing the heavy machine armour designed by academician Chen, the military weapon experts have designed several other models according to the heavy machine armour, one of which is the EOD type. However, it is still in the testing stage. We borrowed these two for this mission, which can be regarded as helping the design Department to carry out actual combat testing." The officer explained to Chen Xinru, while at the same time, two heavy explosive disposal machines also entered the inside of the excavated railway station and found the passage to the underground.

This is also a major feature of the architectural design in the period of suvia. Underground passages are built for air defense.

In those days, this design was still very effective. In case of air raid, ground personnel could hide in air raid shelters and underground passages to effectively resist the damage of air raid.

It's just that this kind of design seems to be inferior nowadays. After all, the air raid shelters under most civil buildings are not deep enough from the ground. With the penetration of modern bombs, hiding in such old-fashioned underground passages or air raid shelters is likely to be directly buried by the collapsed soil layer.Of course, civil buildings are not likely to get big bombs. If it's just ordinary shelling or bombing, the buildings on the ground may be flattened, but people underground still have a chance to survive.

After two heavy-duty explosive disposal machines entered the underground passage, the explosive left over from the suvian era was discovered.

It's also a routine operation. After all, what's sealed up here is an important military base. It's normal to leave some security measures for civilian facilities connected with the base to prevent people from sneaking in.

However, they are all things left over from decades ago. Many layout methods and corresponding elimination methods have long been well known. With the help of the explosive disposal machine armour, two explosive disposal engineers quickly demolished the explosives, allowing other soldiers and staff behind to enter the underground passage smoothly.

After walking through the town along the underpass, they went a little further to reach the destination of this journey, a secret military base sealed up by suvia for more than half a century.
