At this time, Europe.
After burning down the heavy industrial area in Saxony, the Longyan Army withdrew directly from Saxony.
In this battle, Prince Subiz's Holy Crusaders only have cavalry left to use, and the other troops have been defeated by the Dragon Flame Army.
Now that Saxony is also in danger, Liu Zheng believes that the current Holy Crusaders no longer pose any threat to Prussia.
After all, the Saxon troops have now been basically destroyed.
If the Holy Crusaders led by Prince Subitz withdrew from Saxony, then Prussia would have a chance to reoccupy Saxony.
Once again, Sark is in the bag.
Therefore, Liu Zheng concluded that neither the Saxon troops nor the Holy Crusaders could pose any threat to Prussia for a long time.
As for Prussia's other strong enemy, the Austrian troops.
I heard that Austria had captured Silisili and regained control of this rich area. This was a considerable threat to Prussia.
However, Liu Zheng heard that Frederick II successfully defeated the Austrian troops attacking from Silesia using the inverted slash method.
From this perspective, Prussia's southern battlefield is basically in a relatively stable state.
Unexpectedly, so many wars have already broken out before winter has passed.
But this is also good news. Such large-scale wars break out in winter.
The amount of food and materials consumed must be an astronomical figure.
Liu Zheng concluded that for a long time to come, these countries that broke out in winter would not be able to quickly launch large-scale wars in a short period of time.
At least until autumn, the situation on the battlefield should turn into a skirmish.
But this inference is not absolute. After all, there are powerful countries that did not participate in the winter battle.
There are still some variables, but they are not big.
When Liu Zheng came back, he checked out the steam train they built in Austria.
Originally, it was thought that a long war would start in Saxony, so this railway was built to transport troops.
But now it seems that the pace of war is much faster than Liu Zhengxiao thought.
However, after this transportation line is built, it will come in handy sooner or later.
The war is not over yet. With this transportation line, Long Yan's troops can reach Saxony in the shortest time, and then directly attack the surrounding countries from Saxony.
The location of Saxony is almost equivalent to the center of the Shinra Empire, and it is an area with well-connected transportation.
Liu Zheng marched along the railway. Long Yan's army of less than 50,000 people returned from Saxony in a short time. Long Yan was in the port city of Austria.
As soon as Liu Zheng arrived, he heard Li Hongtian's voice before he had time to rest.
"Master Liu, Master Liu, I have something important to report."
Hearing such a voice, Liu Zheng felt his forehead buzzing.
He finally came back from those hellish places where no one even pooped. Before he could rest, this old guy came to disturb him.
Liu Zheng felt cursed in his heart, but he still put on a smile on his face.
He kindly praised Li Hongtian for his hard work during his absence, and that there were no big troubles at Longyan Port under his leadership, and other such things.
Li Hongtian's wrinkled face smiled like a blooming chrysanthemum when he heard these compliments.
"Oh, I'm really embarrassed. I just did some things that were part of my duty."
Li Hongtian saw that someone was missing from Liu Zheng's side and asked hurriedly: "Master Liu, where is the girl next to you?"
Liu Zheng's face suddenly fell, and when he thought of Theresa, he could only sigh endlessly.
He shook his head and said, "You came to me to report something important, so what on earth is it?"
Only then did Li Hongtian remember his purpose of looking for Liu Zheng, and he hurriedly took out a letter from his sleeve.
Li Hongtian handed it over with both hands and said in a deep voice: "This is your home letter. I have been here for a while."
"It's a personal letter from Princess Longyang."
Upon hearing this, Liu Zheng's eyes suddenly shone.
"Xie Chan's letter."
Liu Zheng hurriedly took the letter from Li Hongtian. After tearing open the envelope, he smiled and read the first sentence of the letter.
"Liu Zheng! You bastard, how long have I been away and you still haven't written me a letter? Do you have to ask me to write to you?"
Liu Zheng's face suddenly fell.
Thinking about it carefully, Xie Chan has been away for a long time, and it seems that he has been hanging out with Theresa during this time.
Liu Zheng quickly ignored this sentence and looked down with a guilty conscience.
"I miss you so much. When my parents heard that I was pregnant, they tried their best to prepare delicious food for me every day, such as steamed lamb, steamed bear paws, steamed deer tail, roasted duck, roasted chicken... sauced chicken Bacon, Songhua belly."
"It's delicious. In that shabby place in Europe, except for potatoes, you can only look at the stars with your eyes. It's a pity that you can't see it, otherwise you will be starved to death..."
"Little Congcong can call me brother now."
"My parents and I miss you very much."
"Will you come back for the New Year?"
Seeing this, Liu Zheng sighed. He wanted to go back, but the overall situation was uncertain and he couldn't go back.
After Liu Zheng read this letter, he looked at the second one.
The second piece of paper records the contents of Liangzhou Laboratory.
It said that a British scholar named Stephenson recently came to Liangzhou.
I want to develop a steam train in Longyan that can be used to carry supplies.
Seeing this, Liu Zheng instantly thought of the person Hu Xier and Mo Cheng had written about in their hearts.
"Stephenson..."
Liu Zheng murmured something. The name seemed familiar. Suddenly, in a story deep in his mind, he saw that this person was the one who invented steam trains and railroad tracks in his previous life.
Couldn't these two be the same person?
Thinking of this, Liu Zheng shook his head. This is a different world. Although there are many things that are the same as in his previous life, there are also many differences.
Liu Zheng did not think about these things and continued to read the letter.
After Stephenson arrived, he did make a model of steam trains for transporting supplies.
He redesigned the carriage designed by Liu Zheng and turned it into a carriage that could carry heavy loads, but the weight was too high, which greatly slowed down the speed of the steam train...
Experiments with transport steam trains continued, and there was no offensive yet.
Liu Zheng shook his head. He had never read a similar book on the manufacture of large-scale transportation train carriages, but he also knew that it was not easy to make.
To solve the problem of material sturdiness and load-bearing, there is also the issue of size.
Today's steel can meet the hardness requirements, but there is no way to meet the weight requirements.
There is still a long way to go.
Looking further down, Liu Zheng's eyes suddenly lit up: "The research on generators has made a breakthrough!"
