The morning sun rises in the east, and the city of Suzhou seems to have reached spring overnight.

Above the plaque at the gate of the palace, several spring swallows nested with spring mud, and the fat little sparrows stood next to them and looked curiously; The two palace guards raised their heads and kept an eye on the little sparrow, for fear that the pet of the concubine in this world would accidentally fly away.

It was still early, and the girls in the back house got up one after another, and the maids went back and forth between the corridors.

In Song Yufu's boudoir, the portrait of the man is hung on the wall, the two bookshelves are full of books, and there is a vermilion wine gourd on the desk.

The curtain of the embroidered bed hung down, and in the red futon, Song Yufu's little face was slightly red, holding Xu Buling's arm, still asleep. In just a few days, the slightly green cheeks did not show any change, the only difference was a little less shy and a little more clingy.

Xu Buling lay flat on the pillow, he had already woken up, afraid of waking Yufu, so he didn't get up, and looked at his sleeping new daughter-in-law a little boringly.

Song Yufu herself got up very early, and she always got up before dawn to read, and she couldn't move. It's just that after getting married, this habit obviously has to be changed, the body is already weak, and he is abducted by the bad looker, putting on a strange posture, and every time he is so tired that he doesn't want to move, and he can only get up at dawn.

After the last candle in the cave room, I overslept in the morning, and then Manzhi sneaked over, lying on the side of the bed and asking what, "Fu Bao, did it hurt last night?" What happened to Xu Gongzi, tell me about it~......", Song Yufu almost died of shame at the time, and she didn't know how to describe it, but fortunately, Xu Buling came over and scared Man Zhi away, so he escaped.

Twittering~~

The sound of birdsong outside the window came, and Song Yufu's eyelashes moved, and she gradually woke up and opened her eyes.

Seeing the face of the man close at hand, Song Yufu's eyes were slightly confused, her face gradually turned red, and the hand holding her arm loosened slightly:

"Xianggong, wake up......"

Xu Buling hooked the corners of his mouth: "If you want to sleep, you can sleep more, anyway, it's okay in the palace." ”

"No, I'll be here later......"

Before Song Yufu finished speaking, there was the sound of footsteps trotting outside the room, and the call of 'quack~~', and Zhu Manzhi's voice came:

"Xu Gongzi, I caught a fat goose, I want to roast and eat it, Xiao Ning has to stew, you give attention~......"

Song Yufu heard the goose's sad and angry wail, and was a little puzzled, but her eyes were anxious, she got up from the futon, didn't wear any clothes, ran to the window quickly, and pushed open the window:

"Don't don't, don't bake Bai Shizi......"

Outside the window, Zhu Manzhi smiled and lifted the wings of the big white goose, and saw Song Yufu in a blink of an eye, and wanted to make a few jokes...... Two big balls for nothing......

"Ah~ Fubao, why are you naked, are you ashamed ......?"

Song Yufu looked down, finally came back to her senses, screamed, hurriedly closed the window, and ran back to the embroidery bed.

Xu Buling had already gotten up, and when he saw Song Yufu's panicked appearance, he raised his hand and patted her buttocks:

"They are all married, and there is no man in the back house, what are you panicking about?"

Song Yufu was born in a scholarly family, and she has only been married for a few days, where can she let go, hugging her chest to prevent Xu Buling from looking at it, and then got into the futon, revealing only a small face:

"Xianggong, you pull the full branches away, as well as Bai Shizi and Ah Huang, don't stew."

"How come, sleep for a while, don't rush to get up, they all know you can't get up anyway......"

"Oops ~ Xianggong ......"

"Hehe......"

Xu Buling smiled lightly, attached himself to Song Yufu and kissed her on the forehead, tucked the futon, turned around and walked out of the room.

Zhu Manzhi stood at the door, holding the big white goose in his arms, his face was red and fluttering, and he was still pretending to turn his back to the door, and when he heard Xu Buling come out, he muttered:

"Young Master Xu, what are you doing? No clothes in broad daylight ......"

Xu Buling walked up to him, sent the big white goose that was almost blown stupid by the wind and rescued him, threw it into the garden, and then walked out with a small hand full of branches:

"Manzhi, you usually get up in the sun on your buttocks, why don't you sleep lazy today? Is it jealous and deliberately came to rob the lover? ”

Zhu Manzhi thought carefully about being discovered, so he naturally refused to admit it, and blinked his eyes wide:

"Where is it~ I'll just come over and have a look...... By the way, Sister Xiang'er is looking for you just now, it seems that there is something to show you......"

Xu Buling shook his head and chuckled, and no longer teased Xiao Manzhi, and said:

"Where is Xiang'er?"

"Outside the Hanging Flower Gate...... By the way, there is a big hot spring in the city, but it is comfortable, has Xu Gongzi been there? ”

"Got it, I'll go with you later."

"I'll tell you who's going with you......"

"Isn't it normal for brothers to soak in a bathhouse together......"

"Don't Don't ......"

……

Between talking and laughing, Xu Buling finished cleaning up and came to the palace outside the palace.

Xiao Xiang'er was dressed in a jet-black long dress, dressed exactly like Xiao Qi, standing outside the door of the hanging flowers. Lao Xiao and the two palace staff were talking about something on the side.

Xu Buling walked out of the weeping flower door with a full branch, and said with a smile: "Baby, why do you get up so early." ”

Xiao Xiang'er turned around, made the appearance of the ancient well without waves, and said flatly:

"Call me Qiqi, you have to go out, don't be seen out."

Lao Xiao walked up to him with a cane, and said: "Little prince, didn't you leave a few scrolls of drawings before you went down to Jiangnan, from August last year to now, the ordnance supervisor has been pondering. The princess recently analyzed the situation, and estimated that the imperial court was about to send a decree to transfer the Xiliang army into the customs, and those new objects did not know what the role of the battle array was. ”

When Xu Buling heard this, his eyes were slightly happy. The last time he returned to Suzhou, he drew a few drawings of artillery, and explained the general principle, handed over to Xiang'er to improve, and then sent to the Ordnance Supervision for research and development, although he didn't know much, but after half a year, there should be some results.

"Let's go, go over and have a look."

Xu Buling did not hesitate, took Lao Xiao and others, went out of the palace, and took a carriage to the ordnance prison outside the city.

There are 200,000 mercenaries in Xiliang, and all the armor, grain, grass, and ordnance are self-sufficient, and there must be an arsenal to build armor and bows.

In this world, heavy cavalry and crossbow soldiers are the main combat forces, but there are also rudiments of firearms, such as the 'thunderbolt cannon' with the bamboo tube as the launcher, the 'fierce fire oil' used to defend the city, etc., the power is not large, and the number is even rarer.

Although it is a bit backward in science and technology, it does not mean that the craftsmen of this world are much more stupid than modern craftsmen, which can be seen from the underground palace and sword metallurgical technology under Bodhi Island.

The group came to the ordnance workshop outside the city, hundreds of craftsmen ran back and forth, siege vehicles, vehicles and other equipment were piled up, smoke billowed from several blast furnaces, and the sound of striking iron almost overpowered the noise of human voices.

Lao Xiao took Xu Buling, walked back and forth in the ordnance prison, and came to a small workshop opened up in the rear bank.

There are only a dozen craftsmen in the workshop, and there are huge clay molds in the courtyard, which are being dried. The foreman was a son of the Mo family, named Tian Qisheng, who was also a guest of the palace, and was arranged here to be entrusted with important tasks, and was sitting on top of the powder keg and instigating noodles at this time.

Xu Buling was startled when he saw this scene, and hurriedly protected Xiang'er and Manzhi behind, frowned and said:

"How do you pile up gunpowder on the edge of the wall? Not afraid to tear up the workshop? ”

Tian Qisheng saw that the little prince was coming, and hurriedly put down the noodles, got up and said with a smile:

"Don't worry about the world, it's all empty, and the armory is an iron law that prohibits smoking and fire, and I still know this humble position."

Zhu Manzhi glanced around the workshop and saw a pile of big iron pipes piled up in the corner, and his eyes lit up:

"Xu Gongzi, are you building a cannon battle?"

"Almost."

After Xu Buling was sure that there was no danger, he was relieved, and followed Tian Qisheng to the warehouse behind the courtyard dam, and after the door was opened, he raised his eyes and saw a thick and long red cloth covering.

Tian Qisheng walked closer, raised his hand to lift the red cloth, revealing a cannon painted black with precious lacquer, in order not to affect the strength of the barrel, only a black tiger was drawn on it, or the inscription of King Xu You himself, lifelike, with a 'expensive' word written on the whole body.

Tian Qisheng was a little proud: "Little prince, this thing is a half-year of forgetting to sleep and eating, and the copper and iron consumed are 30,000 catties. ”

Xiao Xiang'er only drew a rough drawing, knew the principle, and didn't know how big the actual effect was, and when she heard this, she frowned slightly:

"Xu Buling, 30,000 catties of copper and iron, you can cast 200 sets of heavy armor, are you sure this thing is comparable to 200 heavy cavalry equipped with armor?"

Lao Xiao also frowned slightly: "Xiliang lacks copper and iron, and the 'Tiger Ben Ride' equipped with 20,000 armor riding equipment, the prince has been saving for sixty years, and many of them were captured from Daqi before Jiazi, I'm afraid it's a bit painful to engage in this thing......

It is not surprising that the two of them can say this. In the battle arrays of previous dynasties, the strongest combat effectiveness is the heavy cavalry with heavy armor, one person and one horse is a steel fortress, each battle often only needs a few thousand armored horses, supplemented by light horses, it can be unstoppable, and tens of thousands of enemy troops can be rushed into the army. Good steel doesn't need to be on the blade, spending 30,000 catties of copper and iron to make this thing is not as useful as 200 heavy cavalry.

Xu Buling walked up to the front of the fire run, raised his hand and touched the body of the iron-hearted copper cannon, and nodded with satisfaction:

"The craftsmanship is burned out of silver, and there will definitely be a lot of waste products in research and development, and when the technology is mature, the cost will naturally come down."

Tian Qisheng nodded lightly: "What the little prince said is right, practice makes perfect, and when a few apprentices are proficient, they can't consume so much copper and iron." ”

Xu Buling looked carefully around the artillery, lay on the muzzle of the gun again, looked at the rifling drawn inside, and nodded slightly:

"Have you tried it? The result? ”

Tian Qisheng raised his hand and pointed to the shooting range where the bed crossbow was debugged: "I tried, the sound is quite loud, but it is not easy to aim, this thing is six hundred catties, it can shoot one and a half miles, and the middle one is divided regardless of the people and horses, but it is not allowed to be used one mile away, it is okay to break the city gate, I am afraid that it will not be able to break the city wall." ”

"Just make it bigger, to three thousand catties, the range must at least exceed that of a bed crossbow...... How much can be made in a month now? ”

"It's no problem to make two in a month, wait for a few apprentices to learn, and add some manpower, you should be able to hurry up."

When Xu Buling heard this, he frowned:

"Two cannons? What's the use of this, at most it can be heard on the battlefield, and it can't turn the tide of the war. At least 1,000 artillery pieces, 20 people are responsible for one, get 20,000 artillery pieces out, and push them to Siberia in a wave......"

？？？

Tian Qisheng and Xiao Xiang'er both rolled their eyes when they heard these inexplicable words.

Although Xiao Xiang'er doesn't know how to cast artillery, there are not a few large copper and iron tools cast by Xiao family's ancestors, and the artillery is just an iron lump to put it bluntly, and the casting process is almost the same. She stepped forward and said:

"Xu Buling, do you think that you know that 'more is good, big is beautiful'? Not to mention the copper and iron raw materials and craftsmen, it takes a lot of time just to open the mold, the clay mold is dried for at least half a month, and it depends on the weather, unless the workshop is expanded, otherwise it will not be cast much in a month. You also asked the shipyard in Lanzhou to repair a few warships, no matter how big your family is, it won't burn like this......"

Xu Buling raised his hand and chuckled: "It's just a goal, not now, to build an artillery workshop in the upper reaches of the Wei River, and after it is built, it can be directly transported to the customs by boat, and it can be directly transported to Qingzhou and Jiangnan by taking the Yellow River and the Yangtze River." I'll go and tell my father about this, Tian Lao just has to bury his head in casting cannons. ”

Xiao Xiang'er is a craftsman herself, and she is not without a concept of the output of copper and iron, and she is still a little hesitant to see that Xu Buling is ready to build a large number of buildings and burn the family funds saved by two generations of Su Wang:

"Xu Buling, is this thing really so important?"

Xu Buling thought about it and felt that it was useless to say more, it was better to see it for believe, so he asked Tian Qisheng to pull out the artillery and try it.

After a while, the four craftsmen pushed the cannons out of the workshop and headed to the shooting range on the side of the ordnance superintendent. The gunpowder was packed separately on the cart to avoid a single spark from exploding.

After the cannon stopped, the craftsman, under the command of Tian Qisheng, used the iron brazing on the gun carriage to nail into the ground to fix the artillery. There are sights on the cannon, and after several months of experiments, the distance, elevation angle, charge, etc., Tian Qisheng weighed the gunpowder, loaded it from the muzzle of the gun and compacted it with a wooden stick, and then loaded it with a solid iron pellet and brought a torch.

Zhu Manzhi has been following behind, and when he saw the appearance of the artillery battle, he suddenly came to his senses and said:

"Xu Gongzi, I'll do something, I'll have some ......"

is still in the experimental stage, Xu Buling dared to let Xiao Manzhi take risks, and pulled Manzhi and Xiang'er to stand far away.

In order to show his skills in front of the little prince, Tian Qisheng did everything himself, and lit the fuse at the end of the cannon with a torch......
