Wu Jin slapped him on the head and reprimanded him: "Who made you really shoot, this is a firearms warehouse!" ”

Zheng Yannian was extremely ashamed, and Wei Jin hurriedly persuaded: "General Zheng doesn't know the rules here, please forgive him." ”

Zheng Yannian was annoyed in his heart, in fact, he knew the rules here, he had been here more than once, but he got carried away for a while and forgot about it.

He hurriedly bowed down and admitted his mistake, "Humble duty knows mistakes!" ”

Wu Jin didn't really want to teach him a lesson, but seeing that he really admitted his mistake, he nodded and said: "If you don't know this time, I'll spare you once, and there can't be a next time,"

"Humble, remember!"

Wu Jin turned around and said to Wei Jin: "Let's go and see the artillery." ”

．．．．．．． Compared with guns, in fact, Wu Jin attaches more importance to artillery, at this time has begun to cast artillery on a large scale, no longer Zhao Lao blacksmith is busy, but there are thirty senior firearms craftsmen to participate together, their average age is forty years old, each of them has at least twenty years of experience in manufacturing various firearms, with their participation, the level of artillery casting has been greatly improved.

They unanimously agreed to use the demoulding method to cast the cannon, and under the repeated experiments, the thickness of the cannon wall was more reasonable, and the iron was tighter, and finally solved the problem of cannon explosion that had been suspenseful, and the craftsmen even built a three-thousand-pound cannon that could shoot the cannonball a thousand steps away.

In a busy figure, Wei Jin led Wu Jin to a three-thousand-pound cannon that had just been cast three days ago, the cannon body was black, two feet long, and there were nine iron hoops, and it was difficult for a person to hug in the thickest place, Wu Jin gently stroked this cannon, the shock in his heart was indescribable, he had to admire the ingenuity of the craftsmen, from the beginning of casting the cannon to the creation of a three-thousand-pound cannon, it only took more than three months, and this cannon did not know how much effort they had to hide.

"This cannon has been called a casting test, and it has failed ten times before it finally succeeded, and it is still nameless, please name it Your Highness."

At this time, Old Craftsman Zhao also hurried over, he was now the technical director of the entire artillery battalion, and he stepped forward to salute, "See Your Highness!" ”

Wu Jin still respects him very much, although many craftsmen have surpassed him in the artillery-making technology, but he is the inventor of the invention of demoulding cannons, without his invention, how could he get such a sharp weapon as artillery in such a short period of time.

Wu Jin returned the salute to him and smiled: "The artillery that Master Zhao gave me last time, I have successfully tested it at sea, and there has been no worrying explosion. ”

Speaking of the bombing, the old craftsman Zhao's face showed a look of shame, in fact, he has not been able to really solve the problem of the bombing, or a craftsman from the capital solved this problem, as soon as he turned around, the craftsman happened to be standing behind him, he hurriedly pulled the craftsman up and said to Wu Jin: "Back to His Highness, the problem of the bombing is solved by this Master Mo, he is the hero." ”

This craftsman Mo is about thirty years old, very bad at words, his face is flushed, and he waved his hands again and again to be humble, "This is everyone's credit, not me alone." ”

Wu Jin saw that he was very honest and had a good impression of him in his heart, so he smiled and said, "Please tell Master Mo how to solve this problem?" ”

When Craftsman Mo talked about technique, his nervousness gradually disappeared, and he spoke smoothly.

"In fact, at the beginning, I also thought that the explosion was caused by a material problem and a bubble in the gun body, but after repeated experiments, the bubble problem was solved, but the explosion still happened, and later I found out that it was due to the thickness problem."

He pointed to the tail of the cannon and said: "Because the propellant is burning violently here, it will have a great impact on the cannon wall, and then the further back, the impact force caused by the gunpowder burning will be smaller, so that I will thicken the tail cannon body, thicken the cannon wall, and then lengthen the cannon barrel, so that not only the cannonball will shoot far, but also the impact force generated by the propellant will be evenly dispersed." ”

Wu Jin frowned, "I remember that the gun body used to be thick at the back and thin at the front, so what's the difference?" ”

Craftsman Mo smiled and explained: "Although the thickness is different in the past, the thickness of the cannon wall is the same, in fact, this is the most dangerous, because the shell is small, the chamber is wide, there is a large gap, once the shell lead is ignited from the bottom by gunpowder, the shell explodes before the muzzle, and the gap is too big, the shell can't shoot far, and now the artillery, only the thickness of the cannon wall is different, but the caliber of the inner wall is the same, the inner wall is only slightly larger than the shell, very smooth, so not only will not explode the chamber, but also the range is farther, so to solve the problem of exploding, Not only the cannon body, but also the shell problem, in fact, only solves the problem of the cannon body. ”

Old craftsman Zhao pulled another craftsman up and said with a smile: "Your Highness, this Master Li is a master of firearms, he has been doing mines for twenty years, and he invented a new cannonball with the principle of mines, so that we don't have to worry about the lead at the muzzle, and when the propellant burns, the cannonball lead will automatically ignite." ”

This is also a very remarkable invention, Wu Jin remembers that during the test, every time he had to light the lead that was dragged to the muzzle of the gun, and then ignite the door lead, which was very troublesome, and when it came to mines, Wu Jin immediately understood a little bit.

At this time, Wei Jin handed a cannonball to Wu Jin, "Your Highness will understand at a glance." ”

The shell is in the shape of a gourd, a lead is exposed in front, and the other leads are in the body of the shell, so that when the gunpowder explodes, a part of the flame penetrates into the front of the shell from the gap between the shell and the barrel, and directly ignites the lead exposed outside the shell, and the shell shoots out, and the lead continues to burn in the shell, and finally explodes, the mine is made in this way, of course, it is not so accurate that it may explode in the air in advance, or it may explode half a day after landing, this is no way, there is no such advanced technology.

Wu Jin nodded, and praised sincerely: "Master Zhao invented the demoulding method, Master Mo improved the cannon body, and Master Li invented the cannonball, these are the three stinky generals, the top one Zhuge Liang, I want to give you a heavy reward, all the cannon masters have rewards, and now the three of you will name this cannon." ”

Since the prince opened his mouth, everyone unanimously asked them to name them, the three of them couldn't refuse, and after discussing for a while, Master Zhao said: "Back to Your Highness, this cannon body is fixed on the ground, and the shape is like a tiger squat, so we will take the tiger as the name and call it General Huwei." ”

Everyone applauded, and Wu Jin praised: "Good! This name is majestic, let's call it General Huwei. ”

At this time, a personal guard stepped forward and whispered a few words to Wu Jin, and Wu Jin smiled at everyone: "I have to go to the dock, another batch of supplies has arrived, everyone please continue to make guns and cannons, and in a few days, I will come to visit you again." ”

．．．．．．．． At the wharf of Jiangning County, a fleet of 80 ships composed of 5,000 stone seas slowly arrived at Jiangning Port, carrying extremely important strategic materials, 1 million loads of hay and 500,000 slaughtered sheep, which Qi Fengwu bought from the Khitan at a high price by taking advantage of Qi Ruifu's friendship with the Khitan.

Cavalry has always been the weakness of the Chuzhou army, mainly because there is no place to raise horses, there is not enough forage, raising a horse, at least four acres of land to grow grass, it is very unrealistic in the southern region, and an army, if there is no war horse, then its mobile combat ability will decline a lot.

Wujin seized Baisha Island and got a strategic place in the back of Qizhou, he planned to transport the 10,000 war horses bought by Qi Fengwu to Baisha Island, but it would take more than a month halfway, how to solve the forage halfway, and seeing that the black beans bought were about to run out, and there was no forage supplement, the horses would have a famine, and the arrival of this batch of forage was simply timely rain.

There are also 500,000 slaughtered sheep, which are important military rations, which can be placed in the underground freezer of the Jiangning wharf, and will not rot in summer.

When Wu Jin arrived at the wharf, the boats moored on the river were unloading, and thousands of dock workers, like busy ant colonies, unloaded bags of frozen mutton and bales of hay from the big boat, and the mutton was loaded onto ox carts and transported to the ice warehouse a mile away, while the hay was directly transported to the small boat, ready to be sent to the east mountain of Taihu Lake, where 10,000 war horses were raised.

"Wu Jin!"

As soon as Wu Jin arrived at the dock, he heard someone calling him, he followed the sound and looked at it, and was immediately surprised and delighted, only to see Qi Yunhuan, who had broken up on Baisha Island, waving to him.

He walked up briskly and asked with a smile, "Why are you on the boat too?" ”

Qi Yunhuan said with a smile: "I came out of Silla and met this fleet at sea, and I knew them very well, so I got on their ship. ”

Qi Yunhuan said, took out a contract and handed it to Wu Jin, "This is the contract to buy Baisha Island, it has the seal of the king of Silla on it, there is no problem." ”

Wu Jin was overjoyed, although he had already occupied Baeksha Island, and the island had in fact belonged to him, but without Silla's recognition, this occupation always had hidden dangers, and now with this contract, it was possible to legitimize a fait accompli, and Baeksha Island officially became the territory of the Danyeong Dynasty, which provided a strategically important base for them to attack Silla and Goryeo in the future.

At this time, Qi Yunhuan pointed to a middle-aged man and said with a smile: "That is the owner of this fleet, surnamed Li, and also a famous businessman in Jiangning Mansion, he opened a Tongtian trading house, specializing in transportation and salt and rice business, Qi Ruifu has always cooperated with him very well, this person has a different relationship with the history of Beiping County, so these materials can be transported from Beiping County, otherwise King Zhao will definitely interfere." ”

Wu Jin felt that this businessman was a little familiar, as if he had seen it somewhere, and he couldn't remember it for a while, the middle-aged man stepped forward and bowed deeply to Wu Jin, "Greet the prince, Your Highness, do you remember me?" We saw it at the birthday banquet in Qifu in the capital. ”

"You are Tongtian Li, Li Jin!"

Wu Jin suddenly remembered that during the birthday banquet of Qi Mansion in the capital, he met Huang Shilang, who was Huang Shilang's friend and a very capable businessman.

Wu Jin laughed, "It turned out to be an old friend, thank you for transporting the goods for me this time." ”

"Where! It is an honor for me to serve His Highness. "This Li Jin is very modest.

At this time, Qi Yunhuan said to Wu Jin again: "This person has a wide range of paths, especially the relationship with several military governments in Yangzhou, Jiangbei is not ordinary, you will definitely be able to use him." ”

Wu Jin narrowed his eyes and laughed, this kind of talent, of course he will be of great use.
