Snowflakes fell, and the earth was covered with a pale layer of white.

This is the first snow of the year, and it can't wait to arrive as early as late autumn, and it also announced in advance that this year's cold winter will be far more severe than in previous years.

In recent years, a winter is as cold as one, due to the wind, the snowflakes blew under the corridor, and immediately came over two guards to hold up a big umbrella for Yang Lin.

Yang Lin waved his hand and stood at the tuyere, feeling the cold wind and snow.

"The area around the Baiyu River is ten times colder than here, and we need to prepare enough cotton clothes for hundreds of thousands of people." Yang Lin sighed and scolded: "Thief Tartar, how can you not freeze to death." ”

Behind him, the young general Liu Qi was preparing to rush to the aid from Hebei's defense line, and passed by here to meet Yang Lin.

Hearing this, Liu Qi asked: "Shaozai, the Baiyu River is freezing in winter, why don't you take advantage of the situation to cover up the past?" ”

"In the ice and snow, fighting with the Jurchen Tartars? I'm afraid you don't know how the 700,000 people of Daliao were defeated by 20,000. ”

Cold is a victorious general, with an astonishing record of extravagance, and he has defeated two unbeatable European strongmen.

Yang Lin doesn't want to be like them, now he can consume it, and it is not too late to fight when the winter passes.

Cut off the Jurchens and the steppe, without the Mongol warriors, and without the loss of Youyan, there will be no northern Han to work for them, and the Jin State established by the Jurchens is much weaker than in history.

As long as he continues to oppress their living environment, sooner or later, he will drive them back to their lair, and then go straight to Huanglong.

The only thing to worry about is that the Tartars are not able to live, after all, this cold is nothing to the Jurchen warriors, who have grown up in this environment since childhood.

What the Song army has to do now is to hold the current line of defense and put them in a cage.

"How to collect some charcoal and send it to the barracks to help them survive the cold winter is practical." Yang Lin said worriedly.

Liu Qi was a little stunned, and then smiled: "Shaozai still doesn't know? The barracks now burn not charcoal, but coal for heating. ”

"Someone in Bianliang made a kind of stove, and with a chimney, the smoke could be discharged, or simply a chimney made of mud. Nowadays, in the area of Youyan, at the southern foot of Yanshan Mountain, several coal mines have been mined, which have been continuously transported to the Great Wall. ”

In the past few days, Yang Lin has been busy rebuilding after the earthquake, but he didn't expect that there has been such progress in the army.

It seems that the folk technology is indeed gradually improving, think about it carefully, this is an inevitable phenomenon, and if you lay such a good foundation, it is a saline-alkali land, which should also take root and sprout, and see the harvest.

If coal is used, it will lead to a lot of technological progress, and I heard that there are already people who have made steam pumping machines in Bianliang.

In the sky in front of him, the snowflakes were getting bigger and bigger, and Yang Lin walked back to the room.

Liu Qi followed closely, Yang Lin was in a much better mood than just now, and said with a smile: "When you arrive at Baiyu River, tell Xiyan that before the snow melts next year, you must not take any further risks, and holding on is victory." If you want to hold the defense line of the Baiyu River, I think the best way is the old fortress tactics of the Western Army. If one is not enough, we will build two, and if two is not enough, we will build a hundred. ”

Xixia just forgot about this tactic, Yang Lin really likes this tactic too much, step by step, steady victory, even if the battle fails, it can't change the trend of cannibalizing the opponent a little bit.

The Great Song Dynasty has a vast territory and a population of more than 100 million, which can be said to be unique in this era.

Why do I have to fight all my family resources and gamble with you on the battlefield, I will consume you little by little, and no one can fight a protracted war with the Han people.

--

In the area of the Baiyu River, the military camps are connected together, opposite to the Tartar across the river.

A series of defeats and setbacks made the arrogant Jurchens begin to unite a little, of course, they were certainly not as sincere as when they started to attack Liao.

Zong Han died, representing the collapse of a large interest group in the Jin Kingdom, and also ushered in a repartition of this power.

Wanyan Zongwang, as Zong Han's ally, benefited the most this time, and many of Zong Han's old subordinates defected to his command.

Among them, the most important thing is to finish Yan Lou's room, although he retreated to the Baiyu River, but Ah Guda did not punish the crime.

Everyone knows that it was the collapse of Mongolia that led to the defeat of Lou Muro. Prior to this, he had won three battles and three victories, and pushed the battle line to Yunnei.

There are many strong walled cities, and there is no need for Yang Lin's order at all, the old Western army knows that to deal with foreign races, especially such a fierce foreign race, it is necessary to build a walled city.

The rammed earth is the base, and the stone covers the base of the wall, and the chimneys emit black smoke.

The soldiers hid in the walled city, surrounded by stoves to keep warm, and as long as the Tartars did not attack, they shrank in warm rooms, and did not even go out except for convenience.

Each walled city is full of buildings of all kinds, either garrisoning troops, or storing grain, grass and military supplies.

If the Tartars come to attack, several adjacent walled cities will be horns and cooperate with each other, and the Tartars will not be bargained for at all.

In such a stalemate, the new army of the Beijing camp supported the Baiyu River, and Yao Pingzhong and others were a little worried, for fear that these people would increase their troops in order to allow themselves to attack.

Now attacking will fulfill the will of the Tartars, and they dream that the Song army will get out of the city and fight with them in the field. That's the equivalent of self-defeat.

Liu Qi entered the camp, first greeted a few familiar generals, and then came to Yao Pingzhong's big tent amid everyone's inquiries.

Yao Pingzhong raised his head, sighed, and asked, "Commander Liu has worked hard from afar, please take a seat." ”

Liu Qi hugged his fists and said: "The last general, Liu Qi, has seen Yao Dushuai, and this time he came here, the last general brought the military order of Shaozai." ”

The generals in the tent were a little nervous, and Liu Qi said: "Shaozai said, let us build more military villages, forts, and walled cities, and then stick to the Baiyu River, and hold this place until the day the snow melts, it will be a big victory." ”

The generals in the tent breathed a sigh of relief, and they were all a little happy, this was the order they wanted to hear the most.

Yao Pingzhong said: "It is not difficult to hold the Baiyu River, because the Tartars also know that it is useless to break through the Baiyu River, and they still need to fight Juyong Pass again." Therefore, the main force of the Tartars has been attacking the defense line of the Great Wall, and if Han Shizhong can hold it, let alone wait until the snow melts, it will not be a problem to hold it for three or five years. ”

As he said, the Great Wall defense line is the most difficult, but fortunately, this area has been operated by Han Shizhong for many years, all kinds of fortifications, secret posts, buildings... It's all there.

And as the Han people in the north returned to their hearts, the battle became easier and easier to fight, and despite the continuous offensive of the Tartars, they never broke through the Great Wall again.

At this time, Zong Han had been dead for half a year, and before the Tartar said that he wanted to avenge him, the mentality of both the enemy and the enemy was changing.
