If Lu Zhou was willing, the railway would have been paved from Luzhuang to the west fortress.

The only reason to stop this plan is because there is swampy terrain there.

Although this is Southern Siberia, in winter, such an environment is a bad frozen area.

Frost soil is extremely sensitive to temperature and has a great impact on the construction of railways.

Such poor frozen soil areas will undergo huge changes in the thickness of the terrain during the temperature alternation of one year.

In summer, the permafrost melts, the volume decreases, and the rails sink.

In winter, the frozen soil begins to freeze and expands in volume, and the rails are pushed up. If this happens repeatedly, it will take less than a year or two to cause the rails to undergo severe deformation, and even when it is serious, it will be twisted into a twist.

....

This phenomenon is the so-called permafrost engineering disease.

This is why the Qinghai-Tibet Railway is difficult to build. On the one hand, the altitude is high. In addition, the temperature difference in the permafrost area during the year is large. Often, it may have to be laid repeatedly over a short distance, and different design plans are required.

Siberia is relatively not that exaggerated, but at least the terrain is complex, so it is completely unrealistic to bypass the thick frozen soil area.

If in later generations, the solution to this problem is to adopt the principle of active insulation of permafrost and adopt the measures of "actively cooling, cooling the foundation, and protecting permafrost".

When encountering extremely unstable thick underground frozen land areas, bridges can also be used to build bridges.

However, these methods are impossible to do with the current conditions of Luzhuang. It would be fine to build one or two railways across the river.

It is still difficult to build a complete Siberian railway in a high-dimensional area.

Along the way, there are swamps, rivers and lakes.

Without power machinery, Lu Zhou would not be able to catch the herdsmen from all over Siberia to build the railway...

Now, the small section of railway north of Luzhuang has strictly chosen the route.

The roadbed is covered with stones of a certain thickness, and there are enough people to protect them.

Even so, Lu Zhou was still not sure that the railway north of Luzhuang could be used for a long time.

......

After receiving the order, Lu Er rushed back to the fortress to the west.

But half a month later, the heavy snow began to fall.

The caravan in Luzhuang still has no movement.

Those were the first people who had been to Europe, and they had traveled the entire route, and they were probably carrying the information that Lu Zhou urgently needed.

It seems that the negotiations with Diana are completely fruitless, and I don’t know what happened.

So that night, Lu Zhou summoned Lu Da and others to prepare to launch a battle in the west in winter.

The Kisk Fort in the lower reaches of the Lena River is familiar to everyone and has been monitored for more than a year.

The reason for not taking it before was that there was a good time to win the battle between the lower reaches of the Lena River and this fortress that is easy to defend and difficult to attack.

We must also be wary of the support of other Russian fortresses.

After all, while the Russians invaded Siberia, they also occupied and opened up important areas.

In terms of military selection.

The people from the art troupe must be brought with you.

The nights in Siberia are very long.

On a cold and cold night, lit a bonfire, musical instruments and singing and dancing can inspire people.

Twenty large trucks were modified with chimney stoves to prevent the bearings from being frozen in windy and snowy days, and personnel could also take turns to keep warm.

In addition, there were also a group of sleds, led by the Wink tribe who were familiar with this environment, using reindeer to pull supplies.

When there is no land in heavy snow, reindeer is often easier to use than pack horses because it is cold-resistant and reindeer is more conducive to walking in the snow.

This is like the herdsmen in the north of the desert. They ride horses in summer and in winter, they must use camels to transport goods.

Lu Zhou even thought about installing a cyclone cannon for the reindeer, but the reindeer was obviously not as calm as the camel.

The cannon ran away as soon as it fired, so the possibility of escaping in the battle is extremely high.

......

This time, Lu Zhou only brought two thousand Dragon and Tiger Army with his "Imperial Commander" and more than one thousand auxiliary soldiers were in charge.

No matter how many people are in this type of battle, it will be detrimental to marching.

When we arrived at the fortress to the west, we brought five hundred cavalrymen who were familiar with the terrain.

Due to heavy snow, the journey took only half a month to walk for a full month.

"Your Highness, there is that river ahead of you.

The herdsmen around said that the upstream flowed from Beihaier Lake.

Wait until here to split into two.

On one side, it flows to the Lena River, on the other side is a tributary of the Yenisei River..."

Lu Er pointed to the vast land in front of him and said.

At this time, Lu Er and others' eyebrows were frozen into ice residue.

In this area, Lu Er took his people to wander around for a whole year.

I have even been to Ob City further away, and I have learned about the environment here in advance.

But Lu Zhou didn't know why, but it was obviously the same latitude as Lu Zhuang, but he still felt it was a little colder.

Even though I'm wearing a polar bear now, my hands and feet were so cold that they hurt.

"Your Highness, this is in a large estuary area.

And there are lakes and swamps around. After the wind blows, it will be frozen into the bone marrow."

A cavalry next to him explained that in such weather, even the joints of the horses were wrapped in plush cloth.

Lu Zhou looked around and found that it was true. If it weren't for winter, he wouldn't know what would be the way to go.

"Where are other fortresses of the Russians? There should be people coming to help when we see our movements."

Lu Zhou asked.

Lu Er replied: "The tribe we control has already inquire around us. If there is any movement, someone will soon convey it."

Sure enough, as soon as Lu Er finished speaking, the neighing of war horses came from afar.

But what came back was not a horse exploration, but an army of nearly a thousand people, most of whom were riding horses, deer, and those who ran behind the animals.

They were covered with animal skins and shields.

The weapons in their hands are also very strange, from firearms to primitive stone hammers.

As they rushed over, bursts of snow stains appeared.

This look reminded Lu Zhou of the Vikings he had seen in a TV series in his previous life.

"Unlike the Rakshasa people, the Russians shouldn't look so stupid."

Lu Zhou said in confusion.

Lu Er also put the telescope at this time and said excitedly: "Your Highness, it's the one who draws the skills.

When siege the city later, let them be cannon fodder!"

Lu Er smiled very badly on his face, and Lu Zhou was very surprised.

It has been two years since Ba Shu let him go from his hands. Judging from the current scale, it seems that he is not very good.

"Ba Shu was defeated four times in the battle that was wiped out by the entire army.

Another time, I was almost dead and was rescued by Gou Sheng and I. The size of the lords in his original territory had basically been exhausted.

They are fighting now, and they are killing the woman before they come out..."

Lu Er explained again.

"That must be how much hatred I have for the Russians!"

Lu Zhou shook his head and sighed.
Chapter completed!
