The bloody battle in Guangning City did not last long.

The reason is very simple.

The incense bottles burning in the Ming army's hands were too cruel. Yang Feng's inspiration suddenly appeared with the thirty barrels of incense water left by him, plus the weapons specially made from the long-neck porcelain bottle, which exerted extremely fierce power in street battles.

The Ming army even developed corresponding tactics based on this as the core.

On the streets of the wreckage of houses in Guangning City, Ming army squads with large shields as their vanguards could be seen everywhere, relying on their numerical advantage to push forward. When the Qing army that was resisting was squeezed and densely, the grenadier suddenly stood up and smashed the ignition bottles to the walls on both sides. The flames burst out instantly swallowed the unlucky Qing army. In the chaos of the latter, the Ming army's bird gunners began to call out close with the help of shield cover, and the bird guns that sprayed flames, and finally completed the thorough cleaning. Then the team continued to move forward, and the spearmen who had become supporting roles behind bleed the wounded Qing army on the ground one by one.

This tactic is very effective.

The bravery of the Qing army and the valiant death are meaningless in front of this thing. The most important battle between soldiers in the era of cold weapons is the dense formation. The soldiers who formed the formation are the strongest. However, the most popular thing about the flames is the dense formation. The splashing flames can instantly turn a Mars into a sea of ​​fire. Those Eight Banners Warriors who rushed towards the Ming army without returning can only turn into charred corpses...

Relying on five thousand burning bottles, in less than two days, the 40,000 Ming army completely cleaned up the city's more than 20,000 Qing army and bannermen.

No one left behind.

The Qing army, which had been out of food for almost three months, was supported by eating the elderly, weak, women and children. There were no women or children in the city, and even the old men over fifty years old were eaten up by their own compatriots, so the Ming army would naturally not be captured.

Of course, such trivial matters are not worth mentioning.

His Majesty, the emperor, has never liked to stay.

However, the Ming army suffered a lot of casualties in this battle. More than 7,000 Ming army died in Guangning, and more than 3,000 disabled people, which is not counted as more than 8,000 minor injuries. This shows that the combat effectiveness of these Qing troops is still considerable, or it means that the combat effectiveness of the army is still worrying.

This also proves that Yang Feng is correct.

With such casualties, if he rashly crossed the Liaohe River to attack Shenyang, he would probably have to fill all the Ming army in his hands into the vast ocean of the People's War. At least tens of thousands of new troops were trained to bring the casualties between the two sides to an acceptable number, he should not think about Shenyang. At least he should not consider the occupation of Shenyang for the time being. It is okay to kill and set fire to make a circle of trouble. Just like the Qing army used to deal with the Ming Dynasty in the past, the initiative is now in his hands, and the soldiers also liked this kind of work. They were in the Korqin tribe, but all the Ming army who participated in the operation made a big profit.

But I have to talk about this later.

With the end of the Battle of Guangning, Yang Feng's 17th year of Chongzhen campaign ended perfectly. Whether in western Liaoning or eastern Hebei, the entire tour stopped large-scale military operations in the controlled area and then moved to the state of Maodong.

Because the sea was completely frozen, even the connection between them and the south was completely cut off. The originally bustling ports and fishing villages were completely closed by thick ice, and even Juehua Island could ride on horseback, and the sea ice in the shape of waves stretched throughout Liaodong Bay. The land, including the land, was covered with ice and snow, the rivers were completely frozen, and birds and beasts were hard to find in the mountains. All cities and villages on the land thousands of miles from Guangning to Zunhua were silent. Those busy years began to hide at home to fight the severe cold in various ways.

Even Yang Feng's arsenal has been in a semi-stop state.

He has no choice.

Whether it is the crucial hydraulic boring machine or the hydraulic forging hammers, they must rely on river water. The ice layer on the stone river can run away, so there is no river water to provide power to him.

"This won't work!"

In the Shanhaiguan Palace, His Majesty the Emperor was lying on a tiger-skin recliner, guarding the burning fire, and holding a memorial to report the output of the bandit guns, saying in a very entangled manner.

His nobleman Jing was standing behind and rubbed his shoulders with his little hands.

Now is an extraordinary period, even if you are later, everything will be simple. There are actually not many people around the emperor. The noble prince Huang Ying is the supervisor. In addition, the princess and Li Xiu, who has been living with food and drink, has also been with the adopted daughter of Jing, Yang Feng, who picked up the child on the way to escape, and raised it with Zhu Wei. There is also the daughter-in-law Meng Guqing who just snatched from Fulin, who has not passed by the door, and her identity is not clear. Anyway, the emperor likes to raise it, so it is popular. Raising a loli and growing up is popular these days. They are the first level of the master. As for the rest, they are sent from the Nanjing Palace, there are less than a hundred palace maids and eunuchs in total. This is thanks to Han Zanzhou's filial piety. Since the chaos, the emperor has become more and more thrifty. Before these palace maids and eunuchs arrived, it is said that only a few vulgar girls were serving the priests.

"Your Majesty, I can't do anything about this."

Song Yingxing said honestly.

He really had no choice. He should say that the emperor is a genius. Not to mention the hydraulic boring machine, other hydraulic forging hammers, hydraulic blowers, etc., all of them are much better after the emperor's improvement. But the problem is that they all rely on river water. After the river water is frozen, they are all decorations. Without these things, the output of the storm gun suddenly dropped sharply. Not to mention that without hydraulic forging hammers, the production speed of the cooked iron plates dropped sharply, let alone without hydraulic blowers, the production of the cooked iron itself also dropped sharply. By the way, it would be great if it was in Jiangnan, and there would be no need to consider this trouble at all.

"Forget it, this is indeed not something you can solve."

Yang Feng threw the memorial aside and said.

There is indeed no other solution to this kind of thing besides using a steam engine, but for the steam engine...

Not bad either.

The key to the steam engine is the cylinder. In theory, this thing does require a boring machine, but it does not mean that there is no room for space, because the earliest steam engine cylinders were actually knocked out of a log wrapped in iron plates with tin foil in the middle. Don’t think that the original steam engine in Europe was very tall, that is actually a brainwave. The Nükmen steam engine was invented in 1704. The technological progress in the feudal era was almost insignificant. However, the efficiency of such a steam engine is worrying. It is unlikely to use it to drive large machines. At most, it can do simple tasks such as pumping. Therefore, if you want a practical steam engine, boring machines are necessary.

or……

Yang Feng suddenly realized that he had made a serious mistake.

What does he do with a boring machine?

Is it difficult to ask Xiaoqian to find a few large-diameter scrap steel pipes?

In the early days, there was no big pressure at all. The cylinders were made of cooked iron, and their ability to withstand pressure was weaker than that of modern large-diameter pipeline steel. Wilkinson's hydraulic boring machine was amazing if it was one millimeter. The tolerance of modern large-diameter steel pipes was about to reach one millimeter. The manufacturer was just a mess! Let Xiaoqian get some such seamless steel pipes, take some time to cut them open, and grind them with fine sandpaper, cast the cast iron and pull the cylinder.

As for the seal...

Watt is good to use hemp rope?

Pistons can be cast.

And it can be cast with pig iron, and the rest is manual polishing.

The crankshaft can also be cast.

It is also cast with pig iron.

Well, this is not needed at all. Early steam engines had a crankshaft, which was just a combination of connecting rods and flywheels. Of course, it was not possible to drive a warship train for him, but it was stress-free to drive the blower. Whether he cooked iron with blast furnace or Pudlin furnace, he had to blow the air. Hydraulic blowing could indeed solve it, but hydraulic power is a very unreliable power in the north.

So the steam engine is really a must.

"After all, it is not enough to follow the steps. This leapfrog development is the king!"

His Majesty the Emperor muttered to himself with a deep face.

He decided to start a steam engine this winter. Anyway, he was idle. He didn't want to go out to cause trouble in this snowy and snowy place. He didn't need to worry about government affairs. There were only twelve counties that the emperor was worried about? You can't exercise with Jing Guiren in the palace every day, right? Jing Guiren's body couldn't hold on. Now he began to persuade the emperor to take a few more for the country like those virtuous concubines in ancient times! I don't know that she was virtuous, but Emperor Yang knew that this scheming bitch really wanted to share the blessings of rain and dew. It's a pity that she was only seventeen years old, so she had to endure that every day...

"I have seen the princess!"

At this moment, Liang Cheng, who was holding the door outside, suddenly said.

"Where has Kunxing gone?"

Yang Feng said loudly.

Then in his stunning gaze, his cheap daughter came over in a pure white fur and covered in snow. There was a little melting water mark on her delicate little face, which was obviously just back from outside. Because her beloved father, His Majesty, was stimulated by the Beijing change, his temperament changed drastically and ignored the court etiquette and so on. The nature of Princess Kunxing, who had no control, began to be released. Recently, she became best friends with the wild girl-like Li Xiu. The two of them played outside every day, and it is said that they dared to go to the mountains to hunt.

"Kunxing meets his father, Kunxing just went to the Great Compassion Academy to pray for his father."

Princess Kunxing said with a bow.

"What a good kid. Be careful to catch a cold on such a cold day. Go back and rest!"

Yang Feng said with satisfaction.

Princess Kunxing quickly quit, pulling Li Xiu who was waiting there outside the door, talking and laughing happily, not knowing what she was doing.

Yang Feng looked at her back silently with loving eyes.

"Does the monk pay taxes too?"

He suddenly asked Song Yingxing.
Chapter completed!
