After the flintlock pistol test was completed, Guo Jiangtou summarized the ideas given by Chen Yan, and then after a little transformation, they could prepare for mass production and equip the army.

The next thing to test is the highlight of the day, artillery!

Compared to the arquebus, this is the real weapon of destruction, the king of war!

With a shout, a thick brass pipe with two wheels was pushed out by many craftsmen.

It looks like it weighs at least a few hundred pounds!

Several craftsmen worked together to push him out.

Chen Yan stepped forward in a few steps, stretched out his hand and gently rubbed it on the cannon body.

"Let's start experimenting!"

With Chen Yan's order, several soldiers stepped forward and began to reload the cannons.

To be honest, this thing is a bit ugly, not to mention the stubby, the gun body is still pitted, and the inner wall is smooth because it has been deliberately polished.

A moment later, with a loud bang, a cannonball about ten centimeters in diameter came out of its chamber, cut a graceful arc, and shot at a boulder a hundred paces away.

The target is so large that you hardly need to aim.

Forehead...... Even if it's far away, they won't be able to hit!

Rumble!

The lead ball hit the boulder, and in an instant the boulder shook, and in the blink of an eye, most of the pieces were gone, turning into small pieces of small stones.

"Shhh...... What a terrible weapon! ”

Wen Haisheng gasped and said, his face full of shock and fear that could not be hidden.

"Great cause can be accomplished, great cause can be accomplished!"

"If this is on the battlefield, this thing will be smashed into the pile...... Hiss ......"

“……”

Everyone was shocked, but Chen Yan smashed his mouth and said with some dissatisfaction.

"Lao Guo, you have to hurry up about the iron cannon, this thing is good, it's just too expensive."

"It's the Grand Duke, Xiao Lao'er must get the iron cannon out as soon as possible, we are already trying the alloy method you mentioned."

Guo Craftsman said.

Chen Yan nodded with satisfaction.

"By the way, how are you preparing for the standardized homework I mentioned? Do I have a clear understanding of the new weights and measures I gave you? Still have questions? ”

For the sake of convenience, Chen Yan has moved many theories from later generations to the present.

For example, the length units are millimeters, centimeters, decimeters, meters, kilometers.

There is also the concept of temperature, the unit of weight, the unit of volume, the precise control of time, etc.

I just don't know how these craftsmen are adapting!

"Governor, everyone has adapted to it, and they are using it recently, which is indeed much more convenient than before."

Chen Yan nodded slightly, if the industry wants to develop in the future, these seemingly inconspicuous things are actually the most important.

Without these, all mechanization and standardization are nonsense!

Chen Yan and his entourage were already ready to leave the workshop, but Craftsman Guo gave Chen Yan a surprise again, and the glass was made.

Although they are still figuring out how to make mirrors, the glass has indeed been made, and although the transparency is particularly insufficient, it is still no problem to fool those rich dogs.

Chen Yan was pleasantly surprised, not because the glass could make money, but because since the glass was available, many chemical experiments could be prepared.

He copied down his former textbooks and gave lectures to the students, but he didn't let them just study and not work.

With glass, the chemistry lab can start to prepare, and all kinds of beakers, graduated cylinders, and glassware can be available.

If there is a chemistry laboratory, will the basic materials be far away?!

However, even so, Chen Yan took out some of the glass crafts and handed them over to the caravan in charge of Ma Liu and Wu Linglong, and asked them to go out and sell them.

Then buy the supplies they need and come back!

……

Fengxiang Mansion, Folding Family Mansion!

The head of the Zhe family, Zhe Keqiu, sat in the top position, and his sons, Zhe Yanwen, Zhe Yanqing, Zhe Yancheng, and his brothers Zhe Ke Shi sat in the lower position.

In the lobby, however, there was a man standing.

With a resolute face, his eyes were full of shrewdness, he was wearing a silk satin robe, and said to Zhe Keqiu.

"Cao Guang, the manager of the Qian family in the southeast, has seen General Zhe!"

"I don't know what happened to Steward Cao coming to find my father?"

Before Zhi Keqiu could speak, Zhi Yanwen also came out to talk.

"I ask General Zhe to send troops to suppress bandits, and return the people of Qinzhou to peace!"

Cao Guang said loudly.

"Qinzhou? That's the territory of the farmer, and we can't get involved. ”

Zhi Yanzhi also spoke.

"Qinzhou is rampant banditry, scourging the people in the township, the people have long been miserable, and they are looking forward to the imperial army to suppress the bandits and give them a bright blue sky."

"Cao asked General Zhe to remember for the people of Qinzhou and send troops to fight for thieves!"

"That's the farmer's territory, do you want me to break the family and turn the farmer around? Are you and the heart? ”

Zhe Ke Xing also said, glaring at Cao Guang angrily, as if he wanted to kill someone.

The momentum of a battlefield veteran on his body, where is Cao Guang, an ordinary person, can withstand it.

Being stunned, Cao Guang's body began to tremble with fear, but he still held his eyes and said.

"Where did General Zhe say this, the Zhe family and the seed family are all courtiers of the Great Song Dynasty, how can you say that whose territory is there?"

"General Seed went on the Northern Expedition to Liao, and the tranquility of Qin Fenglu naturally fell on a few generals."

Zhe Keqiu's eyes were gloomy, he didn't look at him, and listened to Cao Guang with an expressionless face.

To be honest, when he heard that Qinzhou was stirred up by a stream of thieves, he was a little happy.

Tell the seed master to say that the old thief went north to attack Liaoguang and took their own people, this is good, the old nest has been served.

"My Qian family is willing to pay for the army's march, and give three thousand taels of gold and five hundred thousand copper coins to several generals."

Cao Guang gritted his teeth and said.

The large-scale inflow of silver into China was in the middle and late Ming Dynasty, that is, around the time of the Great Geographical Discoveries.

European ghost animals discovered the Americas, tried their best to get silver in the Americas, and then sent them to China one by one in exchange for silk, porcelain, tea and other goods.

Before that, China's currency in circulation had always been copper coins!

After listening to Cao Guang's words, Zhen Keqiu's eyes suddenly lit up.

To tell the truth, he was moved, the price given by the Qian family was not low, just paying for the military was a large amount, not to mention three thousand taels of gold and five hundred thousand copper coins.

In addition, sending troops to Qinzhou can disgust the old thief of the breeder, he is really moved!

"Okay, my family is a courtier of the Great Song Dynasty, and it is right to help the court suppress the rebellion."

"Yan Zhi Yanwen, you all order 5,000 troops and go to Qinzhou to suppress bandits!"

Zhe Keqiu ordered.

Cao Guang's face was a little embarrassed.

Fold can ask for this, and his face sank.

"What's the matter, the Qian family thinks that I have sent too many soldiers and horses, and I don't want to pay for the army?"

Cao Guang's body suddenly shuddered, and he shook his head desperately in denial.

"General Zhe, misunderstanding, I think there are a little fewer soldiers and horses."
