"Canopy!"

A dull crash sounded in the school yard of the artillery battalion, the sound of the wooden pole of the stone machine crashing against the bracket wrapped in thick cotton cloth. The torsion of the two tendons turned into a huge thrust at this moment, throwing a stone six catties up, drawing a graceful semi-circular arc in the air, sliding rapidly after crossing the apex, and finally slamming heavily on the ground sixty or seventy steps away.

"Good!" As the loud cheers sounded, the black-faced Lu Shihu stroked his black and shiny beard and shouted loudly.

"Qingzhi, the deadline given by the Prime Minister has only passed two days, and the first stone machine has already been completed, it seems that in less than sixty days, you will be able to dedicate 300 stone machines to the Privy Minister! When the time comes, there will be no credit, and maybe the foolish brother will be able to follow the light. ”

Chen Dexing dared to make a military order, and he was naturally confident. Jia Rudao gave two months and three days, almost sixty-three or four days. Now, just two days later, the first "prototype" has been successfully trial-produced. Next, as long as the size is enlarged, you can build a stone-issuing machine that meets Jia Yidao's requirements, and with hundreds of craftsmen who can do carpentry work in the artillery corps and at least 600 soldiers who can do the work, 300 stone-hairing machines can be built in 60 days, which can really be completed with your eyes closed. The time given by Jia Rudao is actually very loose.

"Canopy!"

There was another muffled sound, and the "prototype" was still throwing stone projectiles. Lu Shihu glanced at the pile of stones next to the small stone machine, and was a little puzzled.

"Qingzhi, these stones have to be shot out with a stone machine?"

"Yes, after the fight, you have to pick it up and continue until the stone machine is damaged." Chen Dexing said lightly, "In this way, you can know the durability of this stone machine." ”

"Durable...... Sex? Lu Shihu repeated this new term several times, and he already understood the general meaning. Keiyuki: Do you want to know how many times a stone machine can send stones repeatedly? ”

Chen Dexing nodded, "Senior Brother Lu should know that the bow force and string force will become weaker and weaker, and the twisting strings and levers of this stone machine, as well as the crosswood used to block the levers, should have a limit on the number of times they can be used." ”

Chen Dexing's design of the stone machine is quite sturdy, the main frame is made of hardwood, and the key parts are reinforced with iron parts, which has a certain durability, but the catapult device of the stone machine is always a consumable part and must be easy to replace - that is to say, the various parts of this stone machine must be of uniform specifications and can be interchanged!

This is both hard to say and easy to say. The difficulty lies in the fact that the craftsmen are taught by different masters, each with their own standards, and even the ruler used has its own size. It is easy to say because the craftsmen under the command of Chen Dexing now account for the military quota and are Song soldiers. The army has its own laws, and Chen Dexing can use military orders to enforce his standards -- just today, he also ordered the craftsmen in the army to build a batch of measuring tools according to the samples he gave, including rulers, triangular rulers, compasses, protractors, parallel rulers, rectangular meters, and anemometers. Some of these measuring tools were used by the craftsmen of the artillery corps.

In addition to standardizing measuring tools, Chen also plans to divide his more than 100 craftsmen into dozens of squads, most of which only build one part of the stone machine. In addition, there is a team dedicated to inspecting the quality and dimensions of the components, several teams for assembly, and finally a team for checking the quality of the finished product. And in the conspicuous position of each part and the entire stone machine, there will be the name of the craftsman responsible for the construction and acceptance. In order to be held accountable in the event of quality problems!

Under such strict quality control, Chen Dexing is naturally confident to create a high-quality stone machine. However, these stone machines are only the beginning of a whole "national salvation plan". And the second step of this plan is to introduce the three-story slurry battleship into the Great Song Naval Army.

Because in Chen Dexing's view, such a warship with a stone generator and arson bombs is a weapon that can really dominate the East Asian waters.

"Qingzhi, you just said that you still want to build a ship?"

Hearing Lu Shihu's question, Chen Dexing smiled and nodded: "Junior brother just wants to verify the power of the three-layer pulp battleship, if it is really available, it should be dedicated to the privy minister." Senior Brother Lu, would you like Yu to jointly promote this matter? ”

Lu Shihu stroked his beard and frowned: "Qingzhi, the cost of this three-layer battered battleship should be a lot of money, right?" ”

"It's a lot of money, if it's in copper coins, 10,000 guan is always required. However, it doesn't take that much to build a boat for verification, and a thousand is enough. ”

"How...... Verify? Lu Shihu's expression was full of curiosity, and he glanced at the stone machine that was firing stone bombs, "Could it be that you also want to build a small one?" ”

"Build two, one is a single-deck pulp ship to verify the ramming angle, and the other is a double-deck paddle ship to verify the possibility of multi-layer paddle seats." Chen Dexing smiled and sold his plan to Lu Shihu - he had already shown Liao Yingzhong the drawings of the battleship before, but the other party did not understand water warfare at all and had little interest.

Therefore, Chen Dexing believes that the only way to get Jia Yidao to support his construction of a three-story pulp battleship is to prove it. In front of Jia Yidao, show him the power of this Western-style warship. However, Jia Rudao is a busy man, and it is not easy for him to show his face in the midst of his busy schedule to go to the edge of the canal in the east of the city to watch the collision of boats. Fortunately, Jia Rudao sent Lu Wende's nephew to his army at the right time.

And Lü Shihu's uncle Lü Wende was supervising the army to aid Sichuan, but was blocked by the Mongol commander Nülin with pontoon bridges and warships to the east of Lin City, Fuzhou, and it was difficult to enter an inch. And once the Diaoyu City fell, the two armies of Wang Jian and Liu Chuan in Sichuan were definitely destroyed, and the five prefectures of Ding, Li, Chen, Yuan, and Jing, which were controlled by the Lu family, were the first line to resist the Mongol army, and the children of the Anfeng Lu family would die in piles.

Therefore, Lü Shihu was extremely interested in any new weapon that might help Lü Wende break the blockade of the Mongol army. Just as he wanted to inquire further about the details, he heard a disturbing sound, vaguely someone crying and swearing. Then I saw someone push the door and enter the hall, it was Monk Liu who served as the commander of the right army of the artillery army.

"Monk, what's going on outside." Chen Dexing glanced at Monk Liu, only to see the righteous indignation on his face, and he didn't know what was going on.

"Big brother," Monk Liu forked his hand and called Chen Dexing in the order of Qionghualou's righteousness, "The Tartars have driven people to the city, they are all the people of our Great Song Dynasty!" They were all bullied......"

"Is it the people outside Yangzhou?" Chen Dexing frowned and asked.

"More than that, there are so many people, I don't know how many!" Monk Liu said, "It should be a dog tartar driven from somewhere else." ”

"This is the grain and grass that the Beiyu wants to consume Yangzhou City, and maybe there is a mixture of fine crops, these are the usual tricks of the Beiyu!" Lu Shihu touched his beard, and said with a pale face, "Could it be that the privy minister let the people into the city?" ”

"It should be released, the gate of Beiguan is wide open, and the ten-mile long street is full of refugees coming in from outside the city, pouring in like a tide, I don't know how many!"

"Is that so?" Lu Shihu was stunned, Jia Rudao's move of letting the people into the city was obviously unexpected, he glanced back at Chen Dexing, "Qingzhi, I'm afraid that there will be a small work mixed in and take the opportunity to make trouble!" Let's not be vigilant as follows. ”

Chen Dexing nodded and said to Monk Liu: "Pass on the general's order, the whole army is on alert!" Then he said to Lu Shihu, "Brother Shi, let's go and have a look." ”

"Okay, let's go and have a look!"
