Chang'an Equipment Department.

Early in the morning, the firearms camp had sent Qingzhou artillery.

Fang Chengyou circled the Qingzhou artillery and began to record the length and thickness of the artillery barrel. In this matter, his body was still a little sour and soft. This was a trace of yesterday's madness.

After carefully recording every size, Fang Chengyou looked serious. Yesterday, Wang Shizi also promised him that if the imitation is successful, he will receive one hundred thousand taels of silver if he handed over the imitation technology.

Thinking of this, he became more serious. Money and beauty are what he yearns for.

After carefully recording the size of the artillery, Fang You said a pair of craftsmen: "Now let's burn the wax water."

The craftsman received the order and immediately started to light a fire, and carried the wax out of the warehouse to begin melting.

Fang Chengyou plans to use the lost wax method to imitate the Qingzhou artillery. This method is to suspend the Qingzhou artillery in a pond and pour wax water in the pond.

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

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

In seven days, Fang Chengyou got a complete clay mold.

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

Zhao Yuanliang had already told him about the artillery blasting, so in his opinion, pouring with molten iron was not feasible. He also knew that using copper for a long time to cast a fire tube would not be easy to blast the chamber.

So he said: "Use copper water instead of molten iron."

"Copper? As a supervisor, the artillery is so heavy, so much copper is enough." The craftsman said.

After learning about the bombing, Fang Chengyou knew that using ordinary molten iron would not work. He naturally knew that the price of a copper cannon would be more than ten times the cost of a Qingzhou cannon.

But the most important thing at the moment is to imitate the Qingzhou artillery. In this way, he has not only fulfilled his promise to Xiao Wenxuan, but also has an explanation to Zhao Yuanliang.

So he said: "When I say copper, I use copper!"

Upon hearing this, the craftsman had to collect the copper casting and pouring of the entire Equipment Division.

After the 15th, a bronze cannon that was roughly the same size as the Qingzhou artillery appeared in the Weaponry Department.

Upon hearing this news, Xiao Wenxuan was overjoyed and ordered the firearms camp to immediately transport the bronze cannons to the firearms camp for test firing.

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

"This artillery is golden all over, isn't it all made of copper?"

Fiji almost gritted his teeth and said this sentence. This is simply a prodigal. How much does it cost for such a large pile of copper.

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

"This is the artillery imitated by the Department of Equipment? It really is atmospheric."

The prince laughed and said, in his eyes, this artillery was really perfect.

Zhao Yuanliang's eyes were piercing, and he thought that Fang Chengyou really had some skills. He didn't expect to use pure copper for casting. However, after looking at the size of the copper cannon, he couldn't help but feel pain. Compared to the price of the copper cannon, he was still willing to buy Qingzhou Cast iron cannon.

"Test firing." Xiao Wenxuan said coldly. If such an expensive artillery is not comparable to Qingzhou's artillery, he would have the heart to kill Fang Chengyou.

After receiving orders from Xiao Ming, the gunner followed the procedures to load gunpowder and ammunition.

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

Seeing such a scene, the ministers couldn't help but laugh. This power is not a bit worse than Qingzhou artillery.

Xiao Wenxuan's face was even more ugly.

The crown prince and Zhao Yuanliang were also puzzled. The artillery was no different from the Qingzhou artillery. Why was this power so bad?

Fang Chengyou was also dumbfounded, and he didn't know what to say?

"Fang Chengyou, how should I say this? The imitation seems to have failed. The price of this bronze cannon is more than ten times more expensive than the iron cannon in Qingzhou, and its power is actually one-tenth inferior. What is the use of such a cannon? "

Fang Chengyou sweated on his forehead, and he said, "No, the emperor, this shouldn't be the case. This artillery is no different from the Qingzhou artillery. How can it be so powerful?"

"You ask me, who shall I ask!" Xiao Wenxuan said angrily, and now he has no hope of replicating Qingzhou artillery.

Fang Chengyou said at this time: "Is it because iron cannons are more powerful than copper cannons? The emperor, let the next official try again, this time the next official uses iron casting?"

Xiao Wenxuan was actually a little unwilling. He said, "I'll give you another chance. If it doesn't happen, then let this matter go."

Fang Chengyou nodded immediately, and went back to the Equipment Department griefly.

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

In the next month, Fang Chengyou began to change copper to iron, but he encountered the same problem as Zhao Yuanliang. The iron cannon would explode after only a dozen shots, and dozens of experienced craftsmen were killed.

Moreover, the range and power of the artillery are also inferior to Qingzhou artillery.

"Why? Why?" After another iron cannon exploded, Fang Chengyou looked at the Qingzhou artillery. No matter how he improved the craftsmanship, the power of the artillery was not as good as the Qingzhou artillery.

Overnight, Fang Chengyou seemed to be a teenager.

"As a supervisor, your majesty asked Feng Shilang to bring a message, saying that he should not waste any more money on imitations." A craftsman said cautiously.

At this moment, Fang Chengyou was completely desperate, because Xiao Wenxuan was disappointed in him, which means that his career will also end here.

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

"Why? Why?" Fang Chengyou muttered to himself as if he had suffered from hysteria. He still didn't understand why the same guns were not as good as those in Qingzhou.

The Equipment Department failed to imitate the artillery, and the news spread among the officials.

Many people with counterfeit ideas were also disappointed ~lightnovelpub.net~ because this would mean that they had to buy artillery from Xiao Ming.

At the same time, Xiao Wenxuan asked the Department of Equipment to imitate artillery quickly spread to Qingzhou.

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

"His Royal Highness, it is said that the bronze cannon imitated by the Changan Apparatus Department is almost the same as the Qingzhou artillery. Why is the power so much worse?" Pang Yukun asked puzzledly after learning the news.

Speaking of it, Xiao Ming was squeezing his sweat. In fact, the bronze guns imitated by the Chang'an Apparatus Department this time are qualified artillery, because in the early stage, bronze guns and bronze guns have always been the mainstream of artillery. It was not until the quality of steel improved. Cheap cast iron and steel cannons appeared, and then bronze and bronze cannons were quickly eliminated.

The reason why the power of the copper cannon is so bad this time is not the problem of the artillery itself, but the problem of gunpowder.

According to the news that the artillery sent to Chang'an to teach the firearms camp this time, the gunpowder used by Fang Chengyou was the gunpowder of the Armament Department itself, and no gunpowder from Qingzhou was used at all.
