Wu Dapeng and the others did not expect that the Tatar bandit group could send warships here to find them, nor did they expect that they could really be found......

Afterwards, Wu Dapeng concluded:

"This nation has definitely been hacked! I don't believe that Pingzhang Ahmad can guess where we came from and what we are going to do...... But he was able to send a warship to find us here, and they found the damn thing!

I'm scared when I think about it...... Why don't you understand anything, but you know that you must kill us?! ------ if they really killed him, then the Great Song Dynasty would be completely finished...... It's back to square one! ”

At that time, Song Ziqiang said indifferently: "What is black or not, it just happened...... Butterfly effect! ”

Wu Dapeng said meaningfully: "Think about it, what is the reason why this nation always chooses the wrong one at a critical time?!"

Hundreds of schools of thought contended and did not choose, and they chose to depose the hundred schools of thought and respect Confucianism------

During the period of great exploration, a sea closure was chosen that was not allowed to go to sea------

During the period of great trade, a closed country was chosen------

In the era of big data, did you choose ------? ”

Song Ziqiang thought for a while and said, "These don't seem to be the choices of the people, right?" ”

"No matter whose choice it is, why is he not right once?! Let's talk about what happened before the Great Song Dynasty...... Do you think they could have been brainless to choose Lianjin's way to resist Liao? And then, choose the United Tatar anti-gold again?! ”

"Nonsense! They always want to choose a strong group......"

"But why didn't you choose that way then?"

"Didn't you just say before the Great Song Dynasty?"

"Well, let's not discuss it, with us, it will be very different in the future......"

――――――――――――――――――――――――――――――――

The Tatar navy came to attack the mouth of the Badao River, which really did not surprise anyone......

The Tatar bandit group Pingzhang Ahmada asked the envoys to go to the Great Song Dynasty to try to ask for the crystal ball, and at the same time, they asked the navy to send three warships to the big island called Liuqiu, and find those merchants who tried to make formations for the Great Song Dynasty to change the fortunes of the country, and either capture them back, or kill them, in short, destroy them!

Whether others believe it or not, he believes that it can change the fortunes of the country, anyway, he believes it------

By this period, the Tatar bandit group had completely inherited all the naval strength of the original Jin Dynasty, including their naval base ------ Huangdao in Shandong. Pen "Fun" Pavilion www.biquge.info

On October 27, 1161, the first naval battle in the history of the world's navy using gunpowder weapons was fought in the waters of the Yellow Sea in China.

A Southern Song Dynasty sailor general, whose name was Gift Bag, led 3,000 sailors and 120 warships to the base camp of the Jin Army's sailors in Huangdao, Shandong.

The Southern Song Dynasty Navy Division relied on advanced firearms and equipment, that is, bed crossbows and ** incendiary bombs, to defeat the Jin Army's Navy fleet.

But after defeating, they did not take the opportunity to burn down this base camp, but hurried back to repay their merits.

After the Tatar bandit group destroyed the Jin Dynasty, they inherited this place intact, and even the original Jin army sailor fleet personnel.

The Tatar bandit group also brought with it a number of Arab sailors, one of the so-called Semu.

In this way, the composition of the water army of the Tatar bandit group is incomparably complex.

There are the original golden, Arabs, and even blacks!

And, of course, Tatar bandit officers, but very few.

There are still some Tatar robbers who can avoid seasickness.

The base camp of the naval army in Huangdao, Shandong Province received a military order sent by the fast horse, so he asked Yao Mai, the head of the naval battalion, to lead three warships of about 500 stone and lead the 500 sailors to the sea.

Of course, they know where it is, but it will be a bit difficult to go directly to that big island to find someone.

They are going to go to Pinghu Island first to see if there is a chance to occupy it directly, and use it as a base.

Yao Mai, the head of the water barracks, believed that Liuqiu Island was a place infested with wild people and plagues, and it was impossible for them to get supplies there.

Only on the main island of Pinghu do there still be some opportunities.

Yao Mai, the general of the navy, is a member of the Yao family, a local family in Huangdao, Shandong.

This person is well-known in the local area and is known as a civil and military all-rounder.

His family was famous for its many talents during the Great Liao period, whether it was serving as an administrative official in the local area or engaging in naval work, there were countless capable people.

When Daikin arrived, the whole family immediately surrendered again and continued to contribute to Daikin's business, and the family business was thriving, and the number of family members increased day by day.

When the Tatar bandit group came, their whole family immediately surrendered again, and continued to contribute to the cause of the Tatar bandit group, and the family business was thriving, and the number of family members increased day by day.

Tatar Bolpujin is the great commander here, and he likes gold and silver things, so Yao Mai often sends them; The Tatar Brepsin appointed him the head of the naval barracks.

Although the Tatar Commander of Bolpjin was the commander of the navy, he liked to raise horses, and he also brought more than a dozen BMW to his post.

Yao Mai, the head of the water barracks, donated a large piece of his family's field to grow alfalfa and provide it for the BMW to gallop; The Tatar Commander of Bolpjin let the Yao family be responsible for supplying the logistics of the navy------ which was a fat gap.

The general of Brepjin in Tatar likes women, and Yao Mai, the head of the water military camp, chose one of the best women in the Yao family and gave it to him as a concubine; Yao Mai, the head of the water barracks, was the second highest in the Huangdao water barracks to the Tatar commander of the Brejjin, and the other Tatar officers were inferior to him.

For a while, there was no difference in the limelight.

His eldest brother, Yao Yan, was the head of the local administration and had always wanted to make a proposal to the Great Khan Kublai Khan to dig the Jiaolai Canal to connect the north and south.

The Jiaolai Canal from Mawankou in Jiaozhou Bay to Haicangkou in Laizhou Bay will shorten the waterway for shipping grain by several times compared with bypassing the Shandong Peninsula.

If it is adopted, it will be a great achievement, and in this way, the Yao family will be prosperous again under the rule of the Tatar bandit group.

But now is not the chance.

Sincere allegiance to the most powerful force at present is a treasure book for the Yao family in Shandong to survive three dynasties.

This expedition to sea was only to capture a few merchants, so such an operation was a good time to easily reap the merits of the war.

Yao Mai, the head of the naval barracks, tried his best to ask for his life, and the general of Brepjin Tatar immediately agreed.

He took with him three carefully selected sea-going ships, equipped with sailor generals who were usually valiant sailors, and brought with him several bed crossbows and a considerable amount of black fire/powder.

At this time, even the Great Song Dynasty was still at the level of assault muskets, and the Tatar naval army was even worse.

But the great exploits of the Battle of Huangdao of the Great Song Dynasty have changed the way of fighting in this time and space naval battle, this technique is very easy to learn, and the bed crossbow and black fire/medicine bag can be understood by everyone.

At present, the tubular artillery of this time and space has not yet completed the development of technology, and it will not be equipped until the Battle of Yashan more than ten years later.

In fact, even if it is equipped, it is only at the level of twenty or thirty meters, and the quality of the black fire/medicine is too poor.

Therefore, Yao Mai, the head of the water military camp, thought that he had brought the best weapons, and if he caught a few merchants, even if they had some miscellaneous soldiers, it was nothing.

He's all soldiers!

The first stop he chose was Pinghu Island------ waiting for the opportunity to take it!

At this time, Song Ziqiang was thinking about finishing the last work in the current plan.

He's going to cast a bronze cannon!

For them, the high cost of cast copper compared to cast iron is one of the biggest disadvantages.

But this is not what they are worried about, not bad money, not bad craftsmen.

As long as they can build it, even if it is only two, they think it is a huge success!

The ductility of this copper is better than that of cast iron, and purely from the casting process, cast copper can achieve high precision in this time and space, because the craftsmen of the Great Song Dynasty are too familiar with this technology.

Strictly speaking, the Great Song Dynasty was a nation that was good at casting, and the word casting was often used in words.

Especially in the method of casting bronzes, the craftsmen of the Great Song Dynasty almost knew several crafts.

This mainly includes: block method, lost wax method, split casting method and welding method.

At that time, Song Ziqiang directly asked the craftsmen of the Great Song Dynasty to use the block model method, directly put on the pottery mold, and use clay, charcoal powder and plant ash to fire the mold.

The bronze cannon he designed was very lightweight, and it was required to be used not only on land, but also on ships!

The reason why bronze is chosen is because the alloy of copper and tin or lead, its melting point is only between 700~900C, and it does not need the temperature of the lime kiln to melt, and it also has excellent castability, high wear resistance and good chemical stability.

However, the accuracy of cast iron is very poor, in other words, the smoothness of the chamber of the copper cannon is much better than that of cast iron, which is conducive to secondary processing.

In terms of internal chambering processing technology, Song Ziqiang decided to use mules, horses and cattle as the driving force, and used the drilling machine and the tools he brought to process the cast barrel more smoothly.

If you still want to be more cost-effective and simple, you will use bronze in the inner chamber and cast iron on the outside.

The density of copper and iron is different, copper is 8.96x103kg/m3, iron is 7.87x103kg/m3, that is to say, copper is heavier than iron in the same volume.

In this way, it seems that the advantages of the copper cannon have weakened, but the copper cannon designed by Song Ziqiang is also small!

The bronze cannon he designed was 110 centimeters long and weighed more than 40 kilograms.

Judging from the drawings, it is presented as a thin front and a thick rear type, with a caliber of 12 cm in the front muzzle and an outer diameter of 20 cm in the rear of the reloaded ammunition.

The drawings indicate that the gun body consists of the front hall, the medicine room, the tail bottom, and the fire door.

At the same time there is a square groove in the tail section and a small circular hole underneath, which is used for twisting ignition, igniting black fire/medicine to fire shells.

From front to back, there are a total of 9 raised hoops on its body.

This hoop is mainly used to strengthen the strength of the gun body and prevent it from bursting due to overheating.

There are also two gun handles on the gun body, which can be used to adjust the gun body and can also be mounted on the gun carriage.

Previously, Wu Dapeng said in surprise: "Why don't you even have a place to aim?? ”

Song Ziqiang ignored his inquiry, he calculated the amount of charge and the weight of the 12-centimeter caliber lead bullet on the paper, and felt that it was okay, and it would not be a problem to hit a hundred meters!

Song Ziqiang said at this time: "The total cost of dozens of copper coins is only a few dozen yuan, do you want me to get you a re-entry system?" The most humble thing, let's practice! ”

Well, everyone agrees.

When Yao Mai, the head of the water military camp, led a team to attack the Badaohe estuary area, Song Ziqiang was making a request to the craftsmen of the Great Song Dynasty.

Song Ziqiang said at the time: "Can two gun handles be cast directly in succession?" ”

The Great Song Dynasty craftsman said: "If you want to save trouble, it is better to weld later------"

Song Ziqiang understood that they had never seen the power of artillery, so he said: "No, the strength is not strong enough------

At this time, I could only hear the conch "whining" blowing, and soon, there was chaos in the stockade, and many miscellaneous soldiers began to run around!

"The Tatar army is coming, the Tatar army is coming!"

The voice was frightened and poignant------
