Chapter 274

Chang'an equipment department.

Early in the morning, the firearm battalion had sent the guns from Qingzhou.

Fang Chengyou revolved around the Qingzhou gun and began to record the length and thickness of the gun barrel. His body was still a little weak, which was the mark of yesterday's madness.

He carefully recorded every size. Fang Chengyou looked serious. Yesterday, Wang Shizi of Zhao promised him that if the imitation was successful, he would get 100000 taels of silver if he handed over the imitation technology.

Thinking of this, he became more and more serious. Money and beauty were what he longed for.

After carefully recording the size of the gun, Fang Youcheng said to the craftsman, "now go to burn wax water."

The craftsman was ordered to start a fire immediately, carry out wax from the warehouse and start smelting.

Fang Chengyou is going to use the lost wax method to imitate the Qingzhou gun. This method is to suspend the Qingzhou gun in a pool and pour wax water in the pool.

After the wax water solidifies, the craftsman will cut and assemble the solidified wax water, and then a complete mold will come out.

After that, he will fill the wax mold with clay, and finally melt the wax mold, so a gun mold will come out.

In seven days, Fang Chengyou got the complete clay mould.

"As a supervisor, the iron quality of Qingzhou artillery seems to be much higher than ours." Before pouring, a craftsman said.

Zhao Yuanliang has already told him about the explosion of the gun bore, so in his opinion, pouring with hot metal is not feasible. He also knows that it is not easy to explode the gun bore with copper when casting the fire tube for a long time.

So he said, "use copper instead of iron."

"Copper? As a supervisor, this gun is so heavy. How much copper is enough? " Said the craftsman.

When Fang Chengyou learned about the blast chamber, he knew that using ordinary molten iron would not work. Naturally, he knew that using copper casting artillery, the price of this copper gun would be more than ten times the cost of Qingzhou artillery.

But now the most important thing is to imitate the Qingzhou artillery. In this way, he is not only fulfilling his promise to Xiao Wenxuan, but also giving an account to Zhao Yuanliang.

So he said, "if I say use copper, use copper!"

When the craftsman heard this, he had to collect the copper casting materials of the whole equipment department.

Fifteen days later, a copper gun with the same size as Qingzhou gun appeared in the equipment department.

Knowing the news, Xiao Wenxuan was overjoyed and ordered the firearm camp to immediately transport the copper guns to the firearm camp for test firing.

At the same time, some important officials also went to the firearm camp.

"The whole body of the gun is golden. Isn't it all made of copper?"

Fijian is almost gnashing his teeth to say this, this is the black sheep of the family, how much does such a big lump of copper cost.

When Xiao Wenxuan saw the golden gun, the joy on his face disappeared.

"This is the gun imitated by the equipment department? Sure enough, it's great. "

The prince laughed and said that in his eyes, the gun was perfect.

Zhao Yuanliang's eyes were bright. He thought Fang Chengyou really had some skills. He didn't expect to use pure copper casting. However, when he looked at the size of the copper cannon, he couldn't help but feel a pain. Compared with the price of the copper cannon, he was willing to buy Qingzhou's cast iron cannon.

"Test shot." Xiao Wenxuan said coldly that if such expensive artillery can't compare with Qingzhou's artillery, he will have the heart to kill Fang Chengyou.

At Xiao Ming's command, the gunner loaded the powder and ammunition according to the procedure.

With a bang, the shell shot out and flew directly into the woods. With a bang, the shell hit a tree and fell down.

Seeing such a scene, the ministers could not help laughing. The power of the gun was not as good as that of Qingzhou artillery.

Xiao Wenxuan's face became more ugly.

The prince and Zhao Yuanliang also showed a little puzzled. There was no difference between the gun and Qingzhou gun. Why was the power so different.

Fang Chengyou is also silly. He hesitates and doesn't know how to say it?

"Fang Chengyou, how to say that? The imitation seems to have failed. The price of the copper gun is more than ten times higher than that of the Qingzhou iron gun, and its power is even less than one tenth. What's the use of such a gun?"

Fang Chengyou's forehead was sweating. He said, "no, emperor, this is wrong. This gun is no different from Qingzhou's gun. How can it be so small?"

"You ask me, who shall I ask?" Xiao Wenxuan said angrily that he didn't want to imitate Qingzhou artillery.

Fang Chengyou then said, "is iron cannon more powerful than copper cannon? Emperor, let me test it again. This time, I will use iron casting? "

In fact, Xiao Wenxuan was not reconciled. He said, "I'll give you another chance. If it doesn't work out, I'll let it go."

Fang Chengyou immediately nodded and went back to the equipment department.

Zhao Yuanliang and the prince looked at each other, showing a look of disappointment.

In the following month, Fang Chengyou began to use iron instead of copper. However, he encountered the same problem as Zhao Yuanliang. The iron gun only tried to fire more than ten guns, and then it would explode. Dozens of experienced craftsmen were killed.Moreover, the range and power of artillery are not as good as those of Qingzhou.

"Why? Why? " After another iron gun exploded, Fang Chengyou looked at the Qingzhou gun and felt very sad. No matter how he improved his craft, the gun was not as powerful as the Qingzhou gun.

Overnight, Fang Chengyou seems to be more than ten years old.

"As a supervisor, your majesty sent a message to Mr. Feng, saying that you should stop wasting money on imitation." A craftsman said carefully.

At this moment, Fang Chengyou completely despair, because Xiao Wenxuan is disappointed with him, which means that his official career will end here.

And Zhao Yuanliang will not continue to treat him, because he lost the value of being used.

"Why? Why? " As like as two peas in hysteria, Fang Chengyou murmured to himself what he could not understand why the same artillery was not comparable to the artillery of Qingzhou.

The news that the equipment department failed to imitate the gun spread among the officials.

Many people with the idea of imitation were disappointed at the same time, because it would mean that they had to buy guns from Xiao Ming.

At the same time, Xiao Wenxuan let the equipment department to imitate artillery things quickly spread to Qingzhou.

Before that, the artillery of Chang'an had told Xiao Ming about the test firing of the copper gun.

"Your Highness, it is said that the copper gun imitated by Chang'an equipment department is almost the same as that of Qingzhou gun. Why is the power so different?" Pang Yukun asked after learning the news.

In fact, the copper gun imitated by the Chang'an equipment department is a qualified gun, because in the early stage, copper gun and bronze gun were the mainstream of gun. It was only after the improvement of steel quality that cheap cast iron gun and steel gun appeared, and then copper gun and bronze gun were quickly eliminated.

The reason why the power of the copper gun is so poor this time is not the gun itself, but the gunpowder.

According to the information brought back by the artillery sent to Chang'an to teach the firearm camp, the gunpowder Fang Chengyou used was the gunpowder of the equipment department, and Qingzhou's gunpowder was not used at all.
