That is, to fight Emperor Tianzuo, and to fight the Jurchens, there are still the Southern Song Dynasty and Nanyue in the south, and there are many internal matters, such as the Qi army, which took over the control of Fujian from Manichaeism, and the follow-up treatment of Fujian and the inferior gentry and tyrants in eastern Guangdong.

Emperor Lu was all busy flying, and he was looking for his own guilt. He is now sitting in the Central Plains, with strong soldiers and horses, and he can completely slow down. I have to exhaust myself to vomit blood, but why bother?

Now there is news in the Jinzhou battle situation, the army needs longer and thicker artillery to bombard the city, but this cannon is for the sailors......

Why is there a faint sense of disobedience?

Emperor Lu took the fold delivered by Song Jiang's messenger to the fast boat and horse, pressed the discomfort in his heart, and thought about it carefully.

The road ahead is hard to beat, and you have to go down on your knees. Although he chose it himself at that time? Fortunately, things have been completed, and after the sweeping work is over, he will have an easy second half of the year. Because when he came to his senses, the arrangement for the first half of the year was ready to go, so he could only go as planned, but many things in the second half of the year were stopped by him.

The topic turned back to Jinzhou, and this battle was indeed a bit tricky.

This Jinzhou city is located in the north of the Xiaoling River, outside the south city wall is the Xiaoling River, its widest point is four or five miles, that is, from the south of Jinzhou City through the section of the river is also a few miles wide. Not to mention stone artillery, even the existing artillery does not pose a threat to Jinzhou.

The only thing that could threaten Jinzhou was the sailor gunboats that came from the mouth of the Xiaoling River in Liaodong Bay and arrived at the city of Jinzhou along the river. It's a pity that the latter's three-to-five-pound artillery hit the Jinzhou city wall after the Jurchens had consolidated, and it was just scratching.

The Liangshan cannon, which can still pose a threat to Jinzhou City, cannot reach the north bank of the river, and the artillery that can hit the Jinzhou city wall is a little less powerful. The two commanders at the front were clamoring for a longer and thicker cannon, and that the longer and thicker cannon was for the sailors, and that's what happened.

Lu Qian tried to recall the topography of Jinzhou, and he remembered that the city of Jinzhou was located in the middle of mountains and rivers. Seven miles west from Jinzhou City is the famous North Putuo Mountain.

In later generations, many people knew about Putuo Mountain in the south, but they didn't know that there was also a Putuo Mountain here in Jinzhou. For Guanyin in the north of the manifestation of the dojo, has a history of hundreds of years, the south looks at the sea, the north looks at the Taiji, the purple gas comes from the east, the longevity is boundless, it is really a blessed land, the holy realm of the world. It is known as the "first cave sky" in eastern Liaodong and the "first Foshan Mountain" outside the Guan.

North Putuo Mountain is small 20 miles long from north to south, and its west is the land of ravines and mountains, but it can also be detoured, but it is obviously not safe. Because there is also a Xiaoling River between the mountains and ravines. Who dares to say that the Jurchens did not ambush people there? They are a full-fledged fishing and hunting people.

From Jinzhou City to the east is the so-called South Mountain, which is composed of Jiazi Mountain and Daling Mountain, and to the north is the North Mountain composed of Bauhinia Mountain and Baihua Mountain, and is crossed by the Xiaoling River in the middle. And even if the Xiaoling River that has broken through this last barrier enters the coastal area, the north and south mountains are near the Liaohai Sea to the east. In the Hereafter, the land was flat and fertile, and the water was abundant, so it was naturally a good place. But now there are puddles and swamps all over here, just like the eastern part of Shanghai and Hong Kong without correction, the sea tide rises, backs up and rolls up, without the evolution of time, or builds dikes to isolate the backflow of seawater, it is impossible for the people to settle here, let alone teach the army to march.

It can be said that the geographical topography of Jinzhou is indeed easy to fight from north to south, and difficult to fight from south to north.

After considering this clearly, Emperor Lu ordered the Manufacturing Bureau to quickly transport the heavy artillery to the Jinzhou battlefield. There are large-caliber heavy guns in the Liangshanbo Artillery Factory, although there are not many of them, but these cannons with experimental nature are of high quality and trustworthy. The wide river outside Jinzhou is not an insurmountable moat in front of them.

The current amphibious artillery of the Qi army is mainly three-jin guns and five-jin guns, but the Liangshanbo Artillery Factory not only has eight-jin guns and larger-caliber ten-jin guns, but also 12-jin guns, fifteen-jin guns and 20-jin guns. Although the magnification of the latter - that is, the ratio of the barrel length to the caliber, which is an important indicator of the power of a gun, that is, the greater the magnification of the firing range, the greater the magnification - is infinitely close to 10.

This seems to be a very small multiplier, which means that this kind of cannon is still unqualified in the Qi army.

You must know that Emperor Lu must have a multiple diameter for artillery, between 12~~15, but this limit is not without reason. Emperor Lu clearly remembered the shining twelve-pounder bronze cannon during the Civil War between the United States and the United States in his previous life, the Napoleon cannon, which had a diameter of 14.3.

It was precisely because he only remembered the exact size of this Western smoothbore gun that he insisted so much. And because the Napoleonic cannon was a bronze cannon, but the Qi artillery was an iron cannon. That's why he loosened the numbers a little bit. Lu Qian, who knew nothing about artillery, insisted on this.

But he will not make Hongyi cannons, most of the famous Hongyi cannons in the history of the Ming and Qing dynasties in China are about 3 meters long, with a caliber of 110-130 mm and a weight of more than 2 tons.

This artillery is a standard heavy artillery, and it can also be regarded as a siege artillery. The ultra-high magnification gives it an ultra-long range. For heavy artillery, range is indeed an important part of measuring its performance, even in later generations. Dr. Zhu Mingshi said that the Hongyi cannon can "erode dozens of miles with one shot", which is naturally a bit nonsense. Once on the Internet, it became ironclad evidence that later generations ridiculed the unreliable doctors of the Ming Dynasty.

But it is not impossible for the Hongyi cannon to have a range of ten miles.

The performance of the same type of artillery in the West proves that this data is reliable - at that time, the countries of Western Europe already had the concept of territorial waters, and the territorial waters at that time were determined by the range of coastal artillery. In 1703, the Dutch jurist C. van Binkshoek proposed that where the power of weapons ceases, the power on land ends. At that time, the range of artillery was about one mile, or three nautical miles, so many people thought that the width of the coastal sea controlled by a country should be three nautical miles. The length of three nautical miles is 5.5 kilometers.

But that kind of heavy artillery is a problem that only the Chinese emperor will encounter in the future, and now only China in the world has lit up the manufacture of firearms, and China has no opponent in this regard. However, these are not excuses for the shortening of the diameter of the large-caliber artillery of the Qi army.

In the eyes of Emperor Lu, such a large-caliber artillery was only China's technological reserve and the foundation of the empire's strength. He doesn't need a high-caliber cannon now, and the Qi army, which has just lit up the art of artillery, is still in the process of accumulating this technology. Lu Qian was not in a hurry.

He had time to wait for the cannon to pass!

It's just that the fold that was suddenly delivered to his hand right now made Emperor Lu feel a sense of urgency. In other words, he felt that it was necessary for him to accumulate artillery technology and at the same time light up the manufacture of mortars.

Later generations know about the Battle of Constantinople in 1453, when the Ottomans smashed Constantinople's strong defenses with a super cannon. In the military history of the West, this represents the complete decline of fortress fortifications in the Cold Weapon Age. Because Constantinople is the pinnacle of the West's cold weapon fortress.

After that, before the appearance of the fortress, artillery, large-caliber heavy siege artillery, became a nightmare for the defenders.

What Lu Qian was thinking about now was, did he need to build a few super cannons of his own? It's good to be a killer feature.

Mehmed II used a Hungarian gunsmith to creatively create a "17-foot (5.18 m) long, 17 tons, a barrel up to 8 inches (about 20 cm) thick to withstand the huge impact when fired, and a caliber of 30 inches (about 762 mm), enough to accommodate an adult, and the granite shells used to weigh 1,500 pounds (about 680 kg)". Lu Qian felt that he didn't need to make it so big, but he also needed to use a lethal blow when necessary, didn't he?

Just like the current Jinzhou battle situation.

In the overall arrangement of Emperor Lu, the battle of Jinzhou was not important, but it was not completely important. If this place is not taken, how will Emperor Lu form a more direct threat to Liaodong next?

After Yan Yun's first battle, he didn't regard Ah Gu Da and Jurchen as his main opponents, but this didn't mean that Ah Gu Da and Jurchen were not as good as Emperor Tianzuo who came back to life in his eyes?

In fact, Emperor Lu has changed some of his thoughts now, such as the quick victory over Emperor Tianzuo earlier. Now he hopes that Emperor Tianzuo will lead the grassland cavalry and the Qi army to fight desperately, just as he hopes that the Jin and Qi armies will continue to fight in Liaodong. Both sides are consuming, Lu Qian can not care about his own death or injury, but the grassland people and the Jurchens will definitely not be able to stand it first.

In his thoughts, the future Liaodong battlefield will be a bleeding wound for the Jurchens. Only before the Jurchens fled north and returned home, they were asked to shed enough blood, so that he would have enough foreshadowing after cleaning up the Yan Jurchens in the future. At the same time, the vast prairie north of the Yin Mountain is also destined to be the sad place of the grassland nomads.

The First Battle of Jinzhou also gave rise to another problem: the navy needed to build larger warships to carry larger and heavier guns.

The battle situation in Jinzhou called the water division to become vigilant.

Mixed Jianglong is the core figure of the water division, and naturally knows the grand cause of Emperor Lu, and unlike the three heroes of the Ruan family, who "have no great ambitions" and want to attack the city and plunder the land, Li Jun is a person who has the heart to divide the overseas and dominate one side. "How big the heart is, how big the world is!"

Although Emperor Lu promised to divide the feudal seal, many of the civil and military ministers in the court had already told him that they were unwilling to go overseas, and they were only willing to serve Lu Qi in this life.

For example, Li Tieniu is one, and Lin Chong, Hua Rong, Xu Ning, Chao Gai and other generals in the army are also like this. Zong Ze, Zhao Mingcheng, Song Jiang and other important civil officials are also like this. Don't look at Emperor Lu's release of so many knights when he was a vassal, but in fact, there are not many people who are willing to go overseas, but there are by no means too many.

What is the reason for the interior, it must have their own considerations, but Hengzhi chose the latter between overseas vassal and rooted in the Central Plains.

Now Lu Qian can see it very clearly, those who are willing to go out, except for Fang La, who must go out, are Hu Cheng, Cheng Wanli, the family of concubines, and finally Wen Huanzhang, Chai Jin, Li Jun and others.

I'm afraid that just one Southeast Asia can fit them all.

In the eyes of the mixed river dragon, who knew the plan, his enemy was never just a Jurchen, but Japan, but Nanyang, but Tianzhu, the place where the Buddha was born, or even more distant Tianfang.

There are no barbarians there, and Tianzhu and Tianfang are also places where a brilliant civilization was born. Not to mention anything else, just a celestial number born in India makes Li Jun dare not underestimate it.

The numbers that were changed by Emperor Lu, as well as the punctuation marks that were ordered by Emperor Lu to go down, brought them a lot of convenience.

How could those places not be as good as the city of Jinzhou City? Could it be that when the time comes, their sailors will be the spectators?

If so, at the same time that the army was going to attack the city with heavy artillery, the sailors were also shouting for heavy artillery ships.

In fact, not to mention the siege heavy artillery that the army wants, the artillery that the army needs to strengthen at the same time is actually the five-pound cannon that can often be seen on the gunboats of the naval division. And the so-called larger ships and larger caliber naval guns on the side of the sailors are simply shouting. For Li Jun himself, he couldn't figure out how much tonnage the sailor wanted and what caliber of artillery he wanted.

It's just that Emperor Lu knows that in the next time, the Manufacturing Bureau and the Ship Department will have troubles.

But no matter how heavy the troubles of the money leopard and the jade banner pole were, the Jinzhou battlefield, which was vigorously reinforced by the rear, the Qi army won indisputably. (https:)
