"Master Hou!"

"Excuse me, you are busy with you, Ben Hou is just come in and have a look."

Chen Kan nodded to a few busy craftsmen, and kept walking towards the innermost.

If outsiders come in, they will see at a glance that the houses built on the mountainside are only a surface, and the mountainside has been carved out of a huge cavity by the craftsmen of the War Bureau and the Ordnance Prison.

The cavity is lit by smokeless fish oil, so it is a little dim, but very cool.

This cave is where the real firebolt is developed.

The hydraulic stamping device, including the production of the fire gun, also diverts water from the waterfall into the cave cavity, and does not affect the hydraulic stamping device of the treasure banknote division.

At the very back of the cave, several craftsmen were discussing something.

After seeing Chen Kan's figure, several craftsmen looked happy.

A craftsman got up and saluted Chen Kan: "Master Hou, you are here, the villain is talking to find you." ”

Chen Kan came to the side of a few people, looked at the parts on the table, and asked with a smile: "What's the matter, Lao Zhou, what problems are you encountering?" ”

"Master Hou, the toughness of the steel sheet is too poor, after filling the gunpowder a few more times, there will be no elasticity......"

Lao Zhou is the head of all craftsmen and the general person in charge of research and development of new firearms.

After listening to Lao Zhou's question, Chen Kan asked thoughtfully: "Is there no steel with better toughness to replace?" ”

"No, we are already using the best steel in Daming."

Lao Zhou shook his head, a trace of distress on his face.

He could be sure that Hou Ye's theory was not wrong, and the use of mild steel and flint to create a flintlock device could indeed greatly increase the firing speed and range of the firebolt.

But now the biggest problem is the material.

The flexibility of the steel plate is too low, and after three or four firing of the fire gun, it completely turns into a burning stick.

If it can only be fired three or four times, then it is better to continue to use the method of manual ignition, at least there is no limit to the number of fires.

"Come to think of it, there will be a solution."

Seeing this, the only thing Chen Kan could do was to encourage them and comfort them.

There is no way, when it comes to making firebolts, these craftsmen are much more professional than him.

The only theoretical support he could provide had been told to them.

Now he has really been hollowed out, and there is nothing left.

"Failure is the mother of success, not to mention that now you have proved that it is feasible to fire fire, and the next thing to do is to continue to optimize and optimize, Ben Hou believes in you."

"You can try any method, don't be afraid of failure, Benhou is waiting to ask your majesty for credit."

When Lao Zhou and several craftsmen heard this, they immediately patted their chests and promised: "Master Hou, rest assured, the villain will definitely make a fire gun, and he will never embarrass you." ”

poured a bowl of chicken soup into Lao Zhou and several core craftsmen, and seeing that their self-confidence was gradually recovered, Chen Kan patted Lao Zhou on the shoulder: "Is there a finished product, take one for Ben Hou to try the effect." ”

"Yes, yes!"

Lao Zhou answered and led Chen Kan to a dimly lit room.

This room is a special place to store gunpowder and various raw materials.

Within a radius of 100 meters, the room is absolutely insulated from fireworks, and no more than five people have permission to step into this room.

"Your Excellency, please see, this is our latest firebolt, but unfortunately, if you fire a maximum of four bullets, the folded mild steel will lose its effect."

Lao Zhou said with embarrassment, but his face was full of pride.

The fire bolt was fired, saving the time of loading ammunition and ignition, and the old-fashioned fire bolt fired once, and all four rounds were fired.

This is definitely a huge step forward in the history of firecracker research.

Chen Kan stretched out his hand to take it and looked at this new type of firearm from beginning to end.

It was pretty much what he imagined.

After all, the improved drawings were drawn by Chen Kan.

"Try the might."

As soon as Chen Kan's voice fell, Lao Zhou ran to arrange the shooting range and other matters.

Experimenting with the power of the new firecracker, Chen Kan naturally would not borrow the hands of others.

Although such a thing as a firebolt exploding still exists, Chen Kan doesn't think that there will be such a low-level problem with the firebolt made by the craftsmen according to the drawings he provided.

In a fenced open space, Lao Zhou erected a straw man, and Chen Kan raised the fire gun and prepared to start the experiment.

"Bang bang ....."

Four dull sounds echoed, and the straw man not far away had turned into a pile of broken grass.

Chen Kan was about to catch the fifth shot, but when he pressed the trigger, the expected fifth shot was delayed.

"Smoothbore?"

Chen Kan dismantled the firebolt into a pile of parts with the drawings in his memory, and saw that the mild steel that had been folded and redone to redo the spring had broken away from the barb on the trigger.

"Sure enough, it's better than a spring."

Chen Kan shook his head thoughtfully.

With the current steelmaking process of the Ming Dynasty, it is basically impossible to train a suitable spring just now.

But......

Chen Kan pondered for a while, beckoned to Lao Zhou: "Ben Hou has seen it, the problem is that the elasticity of the steel is too poor and the hardness is too high, you can ask the craftsmen of the Ministry of Steelmaking to try to reduce the carbon content in the steel." ”

"In addition, you can also try to improve the bullets, and try to increase the amount of gunpowder in the eggshell as much as possible."

"And the glass on the scope, the purity is too low..."

“......”

As soon as Chen Kan spoke, Lao Zhou took out a small notebook from his arms and recorded it quickly with charcoal.

Because these problems are problems that they ignore or don't find at all when they make them.

Returning the firecracker to Lao Zhou, Chen Kan communicated with him again about his feelings about using the firecracker.

What needs to be improved and what can be done better.

Even though Chen Kan doesn't know how to make firecrackers, his vision beyond the times of 600 years is here, and every opinion in his mouth is something that these craftsmen have never come into contact with.

Seeing that Lao Zhou had recorded all his opinions, Chen Kan encouraged these craftsmen a few more words, and then walked halfway down the mountain towards his wooden house and villa.

The progress of the fire gun is slower than that of the treasure banknote, which is something that Chen Kan has expected for a long time.

However, Lao Zhou was able to make the firecracker to a level comparable to the shotgun of later generations with just a few drawings of his own and a bunch of specious theories, which still surprised Chen Kan a little.

Sure enough, the Han people are the most creative people.

Just provide an idea, and they can follow that idea to create a lot of unexpected things.

I think it won't take a few years for Chen Kan to be able to sweep the grassland with the Ming Dynasty's Makqin heavy machine gun.

Back at the wooden house, the mood affected by Zhu Di and the ministers in the morning instantly became very good.

Chen Kan decided that if there was nothing to do in the future, he planned to live here permanently.

......

In the land of fireworks and willow lanes on the Qinhuai River in Beijing, a woman with a peerless appearance suddenly appeared recently.

The woman's surname is Tang, and as soon as she appeared, it caused an uproar in the Qinhuai River.

Without him, the woman is so beautiful.

The prodigal sons who are so beautiful that they have been nostalgic for the land of fireworks and willow alleys all the year round have changed their prodigal state in the past.

Countless sons and brothers, the second generation of Xungui squandered gold and silver just to see her.

The good deeds even call the woman the Nine Heavens Fairy.

The name of Tang Immortal quickly became famous in Beijing.

It is even rumored that even the two royal highnesses are eager to meet this woman.

On an anonymous painting boat, a woman holds a pen, like a clear lotus, out of the mud but not stained, clear ripples but not demons.

It didn't take long for a picture of the hibiscus coming out of the water to be generated under the woman's pen.

On the edge of the string of the boat, the delicate maid was barefoot, and a pair of smart little feet kept stirring in the cool Qinhuai River, splashing bursts of water.

Even the fish swimming in the water were attracted by the girl's jade feet, and swam between the girl's feet in groups.

This should have been a beautiful picture, but there was an old woman with heavy makeup on the boat, who destroyed this beautiful picture.

Seeing that the woman finally put down her pen, the old woman stepped forward with a fan and twisted her bucket-like waist.

With a bitter face, he said: "Ouch, my little aunt and grandmother, Wuyang Hou has been waiting on the riverbank for a morning, and he is also the nephew of His Majesty today, so why don't you give people a chance to meet each other." ”

"Nope."

The woman had a faint smile on her face, but her mouth was cold and rejecting thousands of miles away.

The delicate maid looked back at the old bustard, and a coquettish smile appeared on her face: "Miss said it, I don't see it." ”

But it was such a delicate smile that made the old bustard shiver unconsciously.

It seems that she is not facing a delicate girl, but a flood beast that eats people and does not spit out bones.

"Oh, this, this, miss, Wuyang Hou has let go, if you don't see him, he will dismantle my broken ship."

The old bustard had a bitter face.

At this time, she is not the old bustard who can determine the life and death of many women at a glance, but just a poor woman who is threatened by the powerful.

But the woman remained unmoved.

"Alas!"

The old bustard sighed suddenly, twisted his waist as thick as a bucket extremely exaggeratedly, and reluctantly turned around and walked off the boat.

These days, the number of people who ask to see Tang Xian is countless.

As the owner of this boat, the old bustard should theoretically make a lot of money.

However, this Tang Immortal made a more generous move and directly bought the painting boat.

The old bustard has also changed from the owner of this nameless painting boat to the old bustard who works for Tang Xian.

Seeing the old bustard leaving, the pretty maid got up and walked barefoot to the woman: "Miss, what are we going to do, after buying this boat, we don't have much silver now." ”

The woman turned her head to look at the maid, and opened her teeth lightly: "It's okay! ”

The maid stomped her foot: "Ouch my young lady, we're really running out of money." ”

"Yes."

The woman always had a faint smile on her face, as if the maid's worries were just trivial things.

"Okay, okay, you're a young lady, you have the final say."

When the maid heard this, her eyes almost rolled to the sky, and there was no respect in her words.

The woman didn't care about her rudeness, and rolled up the dried hibiscus water map: "If you sell it, we'll be rich." ”

The corner of the maid's mouth twitched: "Sell it to?" ”

"Isn't there an emperor's nephew under the ship?"

The woman raised her head, and the meaning of her words was obvious, of course, it was to sell to the wronged boss.

The servant girl tilted her head and thought, "Okay then." ”

"Well, tell them that half a month later, an Oiran conference will be held on the Qinhuai River."

"Oiran convention?"

The maid was stunned for a moment, and then frowned: "Miss, do you want to participate in person?" ”

The woman shook her head: "You can just go." ”

The maidservant shrugged her shoulders and muttered, "I know." ”

"Go ahead."

"Got it, got it."

The delicate maid walked out of the painting boat with the painting in her arms, and saw the old bustard explaining something with a smile on his face, while the young man had an impatient look on his face.

The young man is naturally Zhu Di's eldest nephew Xu Jingchang, as a veteran of the flower field, he was deeply attracted by Tang Xian's cold arrogance at the first sight of Tang Xian.

He has now given up the vulgar powder on the Qinhuai River, and as long as the time is up, he will come to guard under this painting boat every day, just to see the beautiful side.

If Chen Kan was here, he would definitely take a bite out of him: "Phew, licking a dog can't die well." ”

Today is the third day that he has asked to see Tang Xian.

With his identity, if he had been an ordinary woman, he would have climbed into his bed and let him pick it.

But this Tang Xian not only has no interest in money, but also doesn't take his identity into account at all.

Three days have passed, and Rao is a little impatient with Xu Jingchang's cultivation.

"Master Hou, this girl doesn't know how to lift, do you want her subordinates to dismantle her broken ship."

The guards beside him saw that their marquis had been deflated here for three consecutive days, and suddenly had the mentality of humiliating the ministers to death, and stared at the old bustard viciously.

But as soon as the guard's words fell, he was kicked on the ass by Xu Jingchang.

He said angrily: "Idiot, what nonsense are you talking about?" ”

He wanted to demolish the boat, but the key was that it was now in public.

The dignified prince of the country actually bullied a group of ladies for his own selfishness, if this is spread out, how can he mix in the noble circle in the future?

There was a feeling of irritability in his heart, Xu Jingchang looked at the old bustard impatiently: "Xian'er really refuses to see Ben Hou?" ”

"Ouch, Master Hou, it's not that the fairy girl refuses to see you, it's really ......"

The old bustard is now crying without tears, on one side is the Hou Ye, and on the other side is the young lady who has a super terrifying maid, which she can't afford to offend.

"Master Hou, it's not that my young lady refuses to see you."

Just as the old bustard was thinking about how to quibble, the maid's voice suddenly sounded.

"You are?"

Hearing this voice, Xu Jingchang was stunned for a moment, and then a lewd look flashed in his eyes.

This delicate girl looks very good.

Although the length is a little worse than that of Tang Xian, compared to these vulgar fans on the Qinhuai River, there is an extra sense of agility.

He was moved again.

If you don't see Tang Xian today, it doesn't seem bad to bring this woman back.

"Master Hou, the slave Xiaoqing is polite."

The maid came to Xu Jingchang's side with the picture scroll in her arms and saluted him.

Then, Xu Jingchang's breathing became thick.

Seeing this, two dimples instantly appeared on Xiaoqing's smiling face, and then deliberately straightened his chest.

She was well aware of how attractive her figure was to a man
