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

But as expected, they encountered the problem of needing to change rails. Not only that, the so-called station has long been completely buried by snow. To complete the track change operation, they must not only clean out two different widths of rails, but also need to dig out the cranes used for track change operation, the warehouses and platforms equipped with wide rail wheels, and the platform from the snow.

Fortunately, this was not a problem for Chen Xin. He instructed the soldiers on the vehicle to help clear out the two rails, and after finding the wide rail wheels, they asked them to temporarily build a gate with a construction vehicle between the two rails.

Then Chen Xin asked the train they were riding to drive onto the wide rail track through the gate, and directly upgraded the train they were riding with the wide rail wheels found by the soldiers.

As Chen Xindou upgraded, the spacing between the wheels of the train was widened to a suitable width, quickly solving the problem of rail replacement. The soldiers did not need to dig out the crane on the side and then spend several hours lifting the carriage to the wide rail road.

After completing the track change, they moved forward again.

However, after entering Lucia, the road was not as smooth as that in the Yan Kingdom and Kazakhstan.

The entire Siberia was filled with thick snow. The disaster caused by the meteorite impact and the unmanned maintenance after the disaster caused many of the railway tracks here to be damaged, which made Chen Xin and the others often need to go through the vast snowfields and reach the destination they were going to.

This is the depth of the Siberian Great Forest, which is a typical unmanned land. Before the disaster, there is no road leading here except for a secret military railway that can lead to the secret military base deep in the forest.

In order to isolate unexpected situations, someone accidentally got involved here and discovered the secret sealed by Suvia.

Before it was sealed here, the Soviets built a town here to serve soldiers and scientists in military bases. The town has a series of living facilities such as stations, schools, and hospitals, ensuring that soldiers and scientists living here can get all their living needs in the town.

However, with the sealing of the military base, all the soldiers, scientists, and staff who once lived in the town have evacuated, and the town, together with the sealed military base, were sealed in the depths of this large Siberian forest.

If it was before the disaster, the scenery here was still quite beautiful.

With various small town buildings from the Soviet era, the surrounding lush and pristine forests are covered with rolling mountains and a beautiful small lake next to it.

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

Of course, there may be fewer entertainment activities, but there were not many entertainment activities in that era, and life was simpler, so it was not a big problem.

However, now everything here has been covered with thick snow, and there are almost no traces of human life.

"According to the information provided by Lucia, our current location should be the train station, located to the west of the town. The center of the town is an office building, with an underground passage leading to the military base. We can pass through the underground passage connecting the office building from below the railway station." The officer opened the town map provided by the Lucia people, pointed to the names marked in Russian on the map, and explained to Chen Xin.

Chen Xin looked at the map and found that he could not understand the Russian language above, so he did not pay attention to the map. He just said to the officer: "Since you are responsible for the operation and command, then you can make the decision. But be careful, it is difficult to guarantee that this sealed military base was not left behind when Soviet evacuated."

"Please rest assured, we brought special explosive detonation engineers this time, there will be no problem." The officer nodded solemnly. He also considered this, so he not only brought explosive detonation engineers, but also put on heavy explosive detonation mechas specially developed by the military.

When Chen Xin saw two engineers appearing in a row of bomb mechas, he couldn't help but raise his eyebrows and asked in surprise: "Is this a modified version of the heavy mecha I designed?"

"Yes, after analyzing the heavy mecha you designed by Academician Chen, the military weapon experts designed several other models based on the heavy mecha. This type of explosion-removing model is one of them. However, it is still in the testing stage. These two were temporarily borrowed for this mission, and it can be regarded as helping the design department to conduct actual combat inspections." The officer explained to Chen Xinru. At the same time, the two heavy explosion-removing mechas also entered the digging of the railway station and found a passage to the underground.

This is also a major feature of architectural design in the Soviet era. Underground passages for air defense are built underground.

In those days, this design was still very effective. Once an air strike was encountered, ground personnel could hide in air raid shelters and underground passages to effectively resist the killing of air strikes.

However, this design is a bit useless today. 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 this old underground passage or air raid shelter is likely to be buried directly by the collapsed soil layer.

Of course, civil buildings generally have little chance of consuming large bombs. If it is just ordinary shelling or bombing, the ground buildings may be flattened, but people underground still have the chance to survive.

After two heavy bomb discharging mechas entered the underground passage, they were sure to find explosives left over from the Soviet era.

This is also a routine operation. After all, it is an important military base sealed here. It is normal for civilian facilities like this that are connected to the base to leave some security measures to prevent people from entering secretly.

However, it was all left over from decades ago. Many arrangement methods and corresponding exclusion methods have long been well known. With the help of the powerful weapon of the explosion mecha, the two explosion-removing engineers quickly removed the explosives, allowing other soldiers and staff to enter the underground passage smoothly.

After passing through the town along the underground passage, they walked a while before they arrived at the destination of the journey, a secret military base that had been sealed by Suvia for more than half a century.
