"What about the cannon, what about the Franc cannon?"

Li Qing walked briskly.

The Franc cannon can appear in the historical documents of the Ming Dynasty, and it must have a very important role without thinking.

After all...... History books don't write nonsense!

"Go and rest first." Li Hong beckoned a few pro-soldiers to go out, and then said, "Godfather, please come with me." ”

Zhu Wanqing hesitated and followed.

When he came to the inner room, Li Hong tore off the cloth on the large shelf, and a cannon appeared in front of him.

"This is the Franc cannon!" Li Hong said.

"The barrel is too thick, isn't it?" Zhu Wanqing said, "It's so bulky, can it work wonders on the battlefield?" ”

"Yes!" Li Hong said in a deep voice, "I have been studying this artillery for almost a day, and I have basically figured out the principle, I have to say that it is more advanced than our Ming artillery." ”

"Huh?" Zhu Wanqing was taken aback.

Li Qing was not surprised, and said, "Tell me carefully." ”

Li Hong nodded and began to introduce: "Godfather, look, the composition of this Franc cannon. ”

Driven by curiosity, Zhu Wanqing also came up, "There is no difference, it's not all cannon barrels, cannon bellies...... Eh, what's this? ”

"That's the point." Li Hong pointed to the barrel embedded in the belly of the cannon and said, "This, let's call it a sub-cannon." ”

Li Hongtan grabbed the broken with his hand, lifted it hard, and directly lifted the sub-cannon out, and said: "This thing is a detachable independent cannon barrel, which can also be called a cannonball." ”

He handed the sub-cannon to the two of them and said, "In the war, you can put gunpowder and projectiles into the sub-cannon in advance, and ignite the fire door on the sub-cannon to complete the launch." ”

"And then?" Zhu Wanqing looked stunned, and didn't get what her husband wanted to express for a while.

"The benefits are great!" Li Hong said excitedly, "The rate of fire of a cannon with this structure is too fast!"

Do you think, if a gun is equipped with three or four subguns, and then it is equipped with a charge and a reloader, how efficient will it be? ”

Without waiting for the two to speak, he said: "I have calculated, if it is equipped with three sub-cannons, then the total firing time of the first three cannons will not exceed ten breaths, ten breaths, ten breaths and three cannons......"

Li Hong's face flushed with excitement, and he was already a little incoherent.

"Brother Hong, calm down." Zhu Wanqing interjected.

Li Hong took a deep breath, suppressed the agitation in his heart, and said: "The benefits are not only that, godfather, you can see that since the sub-cannon is independent, the gap between each pick and place brings ......."

He didn't know how to express it for a moment.

Li Qing saw his hard work and said for him, "The air mobility brought can greatly extend the life of the barrel and the frequency of firing." ”

"Yes, yes, that's it, that's it." Li Hong continued to introduce the advantages, "The sub-cannon and the barrel are separated, if the sub-cannon is broken, directly replace it, the cannon barrel will not be affected in the slightest, and the maintenance cost will be greatly reduced!" ”

After a pause, "The pressure of such a constructed gun is almost all on the sub-cannon, so the barrel can be made much thinner, which is more conducive to heat dissipation and prolongs the life of the gun!"

Not only that, but after the subcannon is independent, it can devote all its energy to the construction of the subcannon without sacrificing the whole...... Look at this medicine room, it can be made so thick, which greatly reduces the risk of exploding! ”

"In addition, this has a crosshair, a ...... to shine on the door"

Li Hong gently stroked the Furlong cannon, and his expression was ...... It is more gentle and ...... than when she stroked Zhu Wanqing Emotional.

As the chief officer of the naval division, he was far more fond of artillery than any other general.

Without him, fight on the water, artillery first!

In the same way, Li Hong's research on artillery is also very accessible, and in less than a day, he has thoroughly understood all the advantages of the Franc cannon, and not only that, he also drew a structural drawing.

"Talking about so many advantages, let's talk about the disadvantages." Li Qing said.

"Of course, there are shortcomings." Li Hong calmed down slightly, "Cheng Ye sub cannon, defeat also sub cannon, sub cannon and main gun barrel are not one, airtightness naturally cannot be compared with our artillery, the firing range will be reduced a lot." ”

"It's a pity." Zhu Wanqing sighed, "No matter how high the launch efficiency is, no matter how low the maintenance cost is, it is in vain if the range cannot reach that far." ”

"No, you're wrong." Li Hongdao, "The Franc machine can't be far, it doesn't mean that we can't go far, you see this cannon, although the design is exquisite, but the iron-smelting skills are not generally poor, and it can't be compared with our Ming Dynasty at all." ”

Li Hong groaned: "As long as the workmanship is excellent, and at the same time, increase the pressure resistance of the medicine room, and fill more gunpowder, even if the airtightness is poor, it can still achieve the current range, or even ...... It will be farther. ”

"That's right." Li Qing nodded: "Vigorously produce miracles!" ”

"In that case, Da Ming has made a lot of money this time!" Although Zhu Wanqing is not good at military affairs, he also understands the importance of this artillery to the Ming Dynasty.

Not only the naval division, but also the Ming Dynasty had a wide range of applications for artillery in land warfare.

Among the three major battalions, the Shenji Battalion specializes in firearms.

Li Hong laughed, and he was a little crazy: "It's not just that you make a lot of money, you make a lot of money!" ”

"Look at your virtuous ......" Zhu Wanqing pursed her lips, but she was also sincerely happy, not only happy for Daming, but also happy for her husband to make such a great achievement.

Li Qing carefully observed this Franc cannon, touched this, looked at that, and asked happily: "Da Ming imitates it, it's not difficult, right?" ”

"Of course it's not difficult, it's mainly just a number of sub-cannons, and at most a few months of hard work, you can build a better Franc machine...... What a Franco, this name is not good! Li Hong was well versed in the doctrine of take-it-or-leave-it, thought for a while, and said: "Just call it the Great General Cannon!" ”

seemed to think that it was just domineering enough, and added: "Invincible General Cannon!" ”

Li Qing touched his nose and was noncommittal.

The soil is a little dirty, and the domineering is really domineering.

In the mass production of the Ming Dynasty, the name Franc cannon must not be used, like that...... I can't get over the face.

Good thing, good thing, thanks to the artillery sent by the old iron of the Franc machine...... Li Qing also likes it more and more when he looks at it.

"Godfather, don't break it." Li Hong was a little distressed when he saw that his godfather was not finished.

Li Qing: "......"

Zhu Wanqing hurriedly diverted the topic and asked, "Brother Hong, did you seize this from the hands of the Franco?" ”

"Well, it's not seized, it's bought." Li Hong said stupidly, "But I can't do that, it was brought by the king of Manraka." ”

Li Hong cleared his throat and snorted: "Although this artillery is of great use to the Ming Dynasty, I will not show mercy to my subordinates, the king of Manraka is already requisitioning small boats, and he will beat them after a while." ”

Zhu Wanqing: "......"

Cheng Zhai, guest hall.

Xu Jing and Tang Bohu tasted half a cup of tea, and Cheng Minzheng walked in.

The two of them hurriedly got up and said, "Xiaosheng sees the waiter in the process." ”

"Less courtesy, less courtesy," Cheng Minzheng didn't have any arrogance, he took a fancy to Tang Bohu at a glance, and asked, "Xiaoyou is Tang Bohu who is famous in the south of the Yangtze River, right?" ”

"It's Xiaosheng." Tang Bohu said humbly, "It's just a false name, how dare you get an axe?" ”

He is not bent to welcome, the waiter of the Ministry of Rites in front of him has also been known as a prodigy since he was a child.

Twelve-year-old Xiucai, twenty-two-year-old palace examination list, whether it is fame or current achievements, they are the elite of the elite, the most top-notch handful.

is Tang Bohu, in front of this kind of person, he can't be arrogant.

"Huh...... There is no vanity under the fame, so why should Tang Dacai be humble. Cheng Minzheng smiled, and then looked at Xu Jing, "The boy of the Xu family? ”

"It's a little student." Xu Jing made another move, "Adults and nobles don't forget things, but they still remember Xiaosheng, it's really ...... Xiaosheng was honestly afraid. ”

Cheng Minzheng was amused and said with a smile: "The two little friends are both talented people, and they will definitely be the pillars of the country in the future, so there is no need to be restrained and humble.

Now that the spring flowers are blooming, how can we waste this good time, why don't we enjoy the flowers under the pavilion, drink, and compose poems? ”

The two smiled and said: "If you don't dare to ask for it, Lord Cheng will please." ”

Cheng Minzheng smiled heartily, and he was not polite, and walked ahead first.

Cheng Zhai is very large.

Cheng Minzheng's father is the secretary of the military department of Nanzhili, and his father-in-law is the secretary of the Ministry of Beijing and a member of the cabinet; For a long time, it was above 10,000 people under one person, and with the blessing of the two people, Cheng Minzheng not only had a smooth career, but also had a lot of money.

The pavilions and corridors of the house are exquisite and atmospheric, with the elegance of the south of the Yangtze River and the calmness of the north, the air is filled with the fragrance of flowers, and the bees and butterflies dance, which is beautiful.

While appreciating the two, they couldn't help but secretly cheer themselves up: I will do this and this in the future.

Coming to the pavilion, the three of them sat down, and after a while, the wine and food were served.

Cheng Minzheng sighed: "The old man is fifty-four this year, and his body is not good, so he can't do it for a few years, unlike you ......."

After a pause, I couldn't help but think of the matter of competing with Zuo Shilang in the court some time ago, although I had the blessing of the two fathers of Shangshu, I was still constrained everywhere in the court, and said with a wry smile:

"The water in the temple is very deep, and the examiner's business ...... Probably won't be me. ”

Xu Jing said with a smile: "If the coffin is still closed, why did Lord Cheng give up?" ”

Tang Bohu also said: "If the adult appoints and dismisses the examiner, the two Xiaosheng will not dare to come." ”

"Huh...... Also, if you come, I will avoid suspicion. Cheng Minzheng nodded with a chuckle and said, "I can't do it for a few years, and it will be your home field in the future, alas, the temple is dangerous!" ”

"The year when adults know their fate is the time when they are full of energy." Xu Jing patted his ass and began to set it up, "If the two Xiaosheng are lucky enough to be in the first place, they still need to ask the adults for the way of officialdom." ”

Cheng Minzheng said with a smile, "What others teach, may not be as good as their own understanding, in fact, it is nothing, after a few years of being an official, you will understand that small places, big places, in essence, are still that little thing......"

As if talking about something unhappy, he changed the subject and said:

"I have heard the name of the four great talents in Jiangnan for a long time, and I can see it today, it is really extraordinary, can the talented man of Tang Dynasty be willing to write a poem?"

Then, take care of Xu Jing, "Xu Xiaoyou is also going to have a song!" ”

"In front of the great talent, Xiaosheng is still not ugly." Xu Jing sneered, "Brother Bohu, please." ”

Cheng Minzheng also looked at Tang Bohu.

"Okay!" Tang Bohu smiled, "Please ask Master Cheng to ask the question!" ”
