As a general who is familiar with military books and martial arts, Xu Guanzhong's martial arts are not outstanding, but he is higher than many generals in terms of knowledge, which is why Chao Gai promoted him exceptionally. If the Divine Arm Crossbow can be fired in bursts, let alone ten arrows, even if it is six or seven arrows, the firepower will be increased several times. When the centipede ship is full, it can be equipped with six giant crossbows, and if you fire a single arrow, there are only six arrows at a time, and if you can fire it in bursts, the power can be multiplied.

Xu Guanzhong said: "Mr. Ma can really improve it into a burst of crossbow arrows. ”

Ma Hua said: "If it is transformed into ten arrows in a row, I am afraid it will be a little difficult, and it will take a year or two to study, but if I give me six arrows in a row, I will be able to complete the transformation in ten days." ”

"Okay, I'll make a proposition, if you can change it to six consecutive shots, all the hundreds of iron tools you talked about with the big shopkeeper just now will be given for nothing, and another fifty cows will be sent." Xu Guanzhong said.

"Is that true? Can you really bring over fifty cows? MCA also didn't believe it, you must know that it is not easy to transport cattle all the way over, and cattle are easy to get sick on the boat.

Xu Guanzhong said: "You should ask someone to move the iron back, I believe you." As for the cattle that will have to wait for the spring of next year to be shipped to you, you must know that it is not an easy task to transport the cattle over. ”

The next day, MCA called hundreds of people to carry the iron tools back, and MCA said that he would go back to get the tools and go back.

Xu Guanzhong said to Hu Cheng: "If this technology transaction is fooled, the loss will be mine, and I will make my own opinion." ”

Hu Chengdao: "MCA is a smart person, and it is easy to deal with smart people. He's coming, and now they're hostile to Goryeo, and it would be even worse if they offended us again. Even if he deceived us, such a loss would be nothing. ”

"Well, that makes sense. Then I'll set up a workshop on the shore first. Xu Guanzhong said.

Although the sailors were not very proficient in civil engineering, it was not difficult to set up a small workshop in the camp on the shore, and besides, the island was not too cold, but a shed was built out of wooden posts, an iron-making furnace was built, and charcoal was cut and burned on the spot. Blacksmith's tools, carpenter's tools, these tools were available on the merchant ship itself.

Sure enough, MCA came back in the evening of the same day, with ten assistants and many professional tools. Stationed in a makeshift workshop, he began to transform the giant crossbow.

It turned out that Tang Long also built a three-shot giant crossbow, but it was a three-shot crossbow arm, which was equivalent to a frame for three crossbows, and Shangxuan was still troublesome, and only once was launched, he had an advantage. Or three shots in one shot, but the range and power are reduced, so it is not a real burst.

Xu Guanzhong said: "Why did Mr. Ma come here in such a hurry, and he rushed over overnight to work hard. ”

MCA sighed: "The land on this island is fertile and the grain is abundant, but there are no cattle and horses. Although I can make all kinds of tools, I can't make cattle and horses, and I hope to build a giant crossbow as soon as possible. ”

Xu Guanzhong said: "You can rest assured, how are things in the village, have they been arranged?" ”

Ma Hua said: "The Korean people dare not enter the village, I have a lot of traps." ”

I see, after all, their ancestors all played with machinery and traps, and they must have built a lot of trap traps in the deep mountains.

MCA works very seriously, working from morning to night with ten assistants. Originally, there were a few craftsmen in the caravan, and they planned to send them to be an assistant to MCA, maybe they could learn something secretly. But Hu Cheng considered that the long-term cooperative relationship was still not implemented, and he and Xu Guanzhong occasionally went to the workshop to have a look, but Hu Cheng and Xu Guanzhong are not people who play technology, and they don't understand it at all.

For more than ten days, MCA has been disgraced, and he has been very busy and tired these days.

Ma Hua said: "It's done, let's try it." ”

The appearance of the giant crossbow has changed a lot, and there is an extra box of crossbow arrows on it, you must know that it is very difficult for the giant crossbow to fire continuously, and the crossbow arrows are very long and heavy. The sailor pushed the crossbow into a wide area, pulled the trigger, and the bolt flew out, puffing and puffing into the grass in the distance.

"Okay, okay." Hu Cheng clapped his hands happily.

But Xu Guanzhong next to him said: "Although it can be fired in bursts, the distance is too close, it looks like it is less than 100 meters, how to fight in the water?" ”

Hu Chengdao: "Everything is difficult at the beginning, even the crossbow is so powerful, even I, a businessman, know it, if it is so easy to study it, wouldn't it be a bad street, this is a talent, we have to recruit for the group training." ”

As soon as Hu Cheng said this, Xu Guanzhong immediately understood, this matter is indeed in a hurry, where is there such an easy thing in the world, it is not easy to send six arrows in a row, and it is not a master who can't make it at all.

Xu Guanzhong said: "Congratulations to Mr. Ma, this first step of the experiment has been a complete success. ”

Ma Hua frowned: "The distance is too close, and the power is not enough." ”

"This will continue to be studied, and have a good rest for two days, people are not machines, and they can't be burned out for research."

Ma Hua said: "Okay, I'll rest for two days." ”

Xu Guanzhong accompanied Ma Hua to fish in the nearby waters, chatted, and talked about the Central Plains the most, after all, the Ma family moved here from the late Han Dynasty, and the people of the family always spoke Chinese and wrote Chinese characters, indicating that they are not people who have forgotten their roots.

Xu Guanzhong said: "We have spent a lot of time in the group training and are improving the water and wind mills. ”

"Why are you building so many mills, don't all the people have mills in their homes?" MCA asked.

Xu Guanzhong said with a smile: "Haha, don't you know, there are tens of thousands of horses, cows, donkeys and mules in our Yuncheng now. There are so many large animals that eat a lot of forage, and the agricultural area is not a pastoral area, so they can only use grain straw. Chao Tuanlian studied a kind of rice, called Tianwang rice, which can produce 1,000 catties per mu and more than 2,000 catties of dry straw at the same time. I've seen this kind of straw, it's very rough. When the cavalry's horses ate them, they only ate the leaves, and threw away the remaining poles, which caused a lot of waste, so they needed to crush the poles so that the horses would eat cleanly. ”

"I know this, the war horses of the Goryeo cavalry are all good ingredients, but I don't know how Chao Tuanlian improved the mill."

Xu Guanzhong said: "I don't know anything about technical things, I only know that the original copper shaft has been replaced with a new shaft, called a bearing, which is composed of two steel rings, with small steel balls in the middle, and lubricated with castor oil. Friction is greatly reduced. ”

Ma Hua patted his head: "The axis can actually do this, why didn't I think that I would have the opportunity to go to see Chao Tuanlian, but now that everything in the village is managed by me, I am afraid it will be difficult to walk away for a while." ”

"There are always opportunities, Chao Tuanlian is very interested in these new technologies, and I believe that Chao Tuanlian will praise you when he sees you." We have Tang Long who is good at forging and casting, Xie Gang, who is good at ironmaking and steelmaking, Lu Tamping who is good at all kinds of wooden vehicles, and Ye Chun who is good at shipbuilding. Ye Chun is now improving our warships, changing the oars into water wheels to reduce manpower. ”

"This team is good, and we need to cooperate to engage in technology. I'm not good at casting, forging and timber shipbuilding, I'm good at mechanics. MCA said.

Three days later, MCA began to research again, and it didn't take long to find the problem, which was that the spring and steel plate were not strong enough.

MCA has found a problem, but how to overcome this problem is difficult, and it is not a problem that can be solved in ten days or eight days. As soon as I calculated the time, it was almost the wax moon, and it was time to go back.
