Lu Sanlang has always felt that he is very smart since he was very young, and even has a kind of secret joy that is unique to the world, and after receiving Zhang Shou's affirmation, Ge Yong's affirmation, and the emperor's praise, his self-confidence has swelled to the extreme. Today, however, he discovers once again that he doesn't know everything.

Especially the drawing that Zhang Shou took out and showed to Guan Qiu, Zhao Si and Luo Xiaoxiao, after he leaned over and looked at it, he only felt that the parts were weird, and he didn't understand what they were at all, and after a while, his scalp was numb and his head was dizzy.

Of course, if he knew that Zhang Shou had added a bunch of very complex force decomposition diagrams in order to combat a guy like him who had a good talent in mathematics, it would not have been so painful.

As for Guan Qiu and the others, Guan Qiu knows a lot of words, and the other two people don't know a lot of big characters, but even Guan Qiu, except for looking at Zhang Shou's broken and fragmented parts diagram, he still can't understand anything about the notes like a book from heaven.

But the last two are people who have studied carpentry and blacksmith work for many years, they have never eaten pork and watched pigs run, Zhang Shou has already picked out the word grinding machine commonly used by jade craftsmen to them, they exchanged heads for a while, and finally roughly understood what Zhang Shou drew called lathes, and what kind of drilling and boring things are it.

Naturally, the wooden structure is made by Zhao Si, and those used for cutting and drilling tools are of course things that Luo Xiaoxiao has to ponder. This burly young man, who is not too old but has a figure similar to that of Carpenter Sun and Blacksmith Zhang, scratched his head, and then asked: "The grinding machine and knives used by the jade craftsman must all be made of steel, Dr. Zhang, you should be the same, right?" ”

Zhang Shou nodded and said: "I heard Lingshi say that at the beginning of my Chaocao creation, it was a great steel-making, and when Taizu was ten years old, the world's iron smelting was several times that of the Yuan Dynasty, and even exceeded the peak period of iron smelting in the Song Dynasty. And because the Ordnance Bureau wants to make artillery and various kinds of firecrackers, etc., fine iron alone is not enough, and many parts must use good steel, so the Ordnance Bureau has the most blacksmiths. But many folk ironware is also made of good steel, which shouldn't be difficult, right? ”

Luo Xiaoxiao hurriedly responded: "That's right, so Master Sun said that he was the best carpenter in the capital, at most someone scolded him for being self-righteous, but in fact, there are always those in the top three." But my master didn't dare to say that he was the best blacksmith. However, the master is quite famous among the blacksmiths in the capital, except for the Ordnance Bureau, and he can easily get good iron and steel. ”

Seeing that Zhang Shou had such an attitude, he said embarrassedly: "But the steel that has been fried and sent over has a fixed number, but I am afraid that I will have to use Dr. Zhang's name to talk to the master, otherwise I will only be scolded back." ”

Regarding Luo Xiaoxiao's statement, Zhang Shou was naturally not surprised. In this year, even if it is a large-scale steel smelting, the output of steel may be the sum of all other countries in this era, but it can be called the top wrought iron of steel, which is a good material used in weapons and various high-demand trades, naturally not Luo Xiaoxiao can come forward.

And when Luo Xiaoxiaozi carefully inspected the shape of the knife, Guan Qiu was already annoyed by asking Zhao Si one question after another. Zhao Si didn't really like this little junior brother who didn't seem to have a good brain, although he didn't know why Zhang Shou wanted such an ineffective person, but it didn't prevent him from respecting people.

At this time, he didn't care about Guan Qiu, and asked Zhang Shou about the size and materials of the wooden components on the drawings, etc., and only then did he put his mind at ease when he got the reply of "you look at it" from Daluhua. After all, looking at the drawings, you know that Zhang Shou is just a preliminary idea, if you really have to intervene in everything in the future, then they will only be unable to do anything in the future!

And seeing that he couldn't intervene, Lu Sanlang was not discouraged, he simply quietly withdrew from the table and called Ah Liu outside. Seeing that the elusive young man really appeared in front of him in three moments, he asked in a low voice: "Mr. Xiao said before that he wanted to collect a blacksmith shop near Guozijian, you should have seen it a long time ago, right?" Tell me the place, and I'll buy it. ”

If it is in front of ordinary people, Lu Sanlang's arrogance of buying a shop is like buying cabbage, which will undoubtedly make people jaw-dropping. However, Ah Liu was not an ordinary person at all, he glanced at Lu Sanlang deeply, and then asked with some confusion: "Do you still need to buy it?" ”

Even if Lu Saburo was a very strong person in the past, he still couldn't help but stare at Ah Liu with a numb scalp, and only asked in horror for a while: "If you don't buy it, how are you going to take down that shop?" You know, although Mr. Xiao is very powerful, but in some places he is still quite decent, you must know that you are ingenious, he has to lose his temper! ”

Ah Liu said lightly: "It has been haunted for four months, the house prices have plummeted, and there have been several owners before and after, and the blacksmith shop is the fifth. ’

Lu Saburo was dumbfounded: "Could it be your ......?"

Ah Liu glanced at him with a foolish gaze: "At that time, I hadn't been to Beijing yet. ”

Lu Sanlang realized that he had asked a stupid question, and immediately laughed dryly: "According to what you say, the blacksmith shop will close sooner or later, and the blacksmith may have been in a hurry to find a home, so it seems that there is really no need to hurry...... However, can a haunted house be inhabited? ”

"I'm here, what the hell are you afraid of?"

With such a simple and neat answer, Lu Saburo was speechless for a moment. Indeed, what evil spirit under heaven could be more terrible than this one? After he and Zhu Er had a grudge with a glass of wine before, Zhu Er talked about the time when he suffered a loss under Ah Liu's hands, it was simply silent. Therefore, he laughed unnaturally twice again, and could not help but mourn in silence for the "evil ghost" in the blacksmith shop.

"But you're right, the money still has to be paid, otherwise the young master will go back and be long-winded." Ah Liu glanced at Lu Sanlang as he spoke, and a shallow smile appeared on his face after saying a few more words, "You look like a rich boy who doesn't know anything about the world, I'll follow you for a trip." ”

I just said to go, you said no, I said no, I said no, and you said go...... Lu Sanlang muttered in his heart, but in the end he didn't carry it with Ah Liu, who didn't play cards according to common sense, and said with a smile on his face as soon as his eyes rolled: "But let's go, won't there be no one watching on Mr. Xiao's side?" If someone with bad intentions comes to eavesdropping......"

"Do you understand?"

Lu Saburo was once again dumbfounded by Ah Liu's words. If a carpenter or a blacksmith comes, you should be able to understand it, but you also know that the only person who will do such a thing as listening to the corner is a professional who listens to the corner...... Those guys really don't understand.

At that moment, he hurriedly agreed, but when Ah Shou told him that the blacksmith shop was two streets away, and let him walk in front, he was full of energy.

Let such a killer-like guy walk behind him, he can understand what it means to be like a thorn in the back!

Although he found that Lu Sanlang was missing, he thought that there was Ah Liu watching outside, and Lu Sanlang was also an extremely smart person, so he didn't need to worry too much, so Zhang Shou didn't take it too seriously. He had also discussed today's technological achievements with Carpenter Sun and Blacksmith Zhang in Lu Saburo's small dark room before, but at that time he was more of a listener, which is like being able to discuss unscrupulously now.

What's more, he had already made a contract with the three of them at the Sun family and the Zhang family last night.

Therefore, Zhao Si and Luo Xiaoxiao asked one by one in line with the principle of prudence and caution, and he explained to them very naturally. However, when Zhang Shou said to Luo Xiaoqi, because there are a lot of spring parts, he might as well try to make a manual spring winding machine, he suddenly came to life.

"I've heard Master say that this kind of spring is commonly used in the Ordnance Bureau, so there is a winding machine specially used to make springs, but that's a secret, and most of the craftsmen who can do it outside will be recruited by the Ordnance Bureau."

Zhang Shou saw it last night, although Carpenter Sun said that he was fierce to Guan Qiu, but in fact, on the way to find Blacksmith Zhang last night, people knocked on the side to find out the usefulness of Guan Qiu, and then sighed how difficult it was to entrust the child to his old friend, and the voice outside the strings was very worried about that little apprentice.

Therefore, seeing that Zhao Si was very surprised by Guan Qiu's casual secret, obviously knowing nothing, he smiled and said, "Wei Nanbo of the Ordnance Bureau, I said hello." So, even if the winding machine is made, you don't have to worry. If you can't do it, then you can wrap it by hand first. But like Xiao Guan said, since it's confidential, I'll go back and send two more people as guards, just in case. ”

Zhang Shou thought as he spoke, and when he turned around, he asked Yang Hao and Qiao, who were idle at home until they were bored and had nothing to do, to come over and act as guards - both of them were very powerful country boys who had practiced a little martial arts, and it would be a good thing if they could be interested in this and learn the skills of blacksmiths and carpenters. Of course, if the two of them are not interested and have no talent, then they will be purely caretakers.

With these words, Zhao Si and Luo Xiaoxiao were all relieved, but Guan Qiu was silent again until Zhang Shou took out another drawing again. Zhao Si was first surprised: "This ...... It looks like a spinning machine, right? I used to do it with Master for someone, but how did it turn upside down? ”

Guan Qiu stared at the big wheel, as if he couldn't even breathe, and after a long time he said with some difficulty: "This spinning machine is different from what Master and Senior Brother Zhao make for people, this spinning machine has many spindles, and the position of this wheel seems to be able to drive ......."

Zhao Si quickly came back to his senses. He has been following his master Sun Carpenter for 12 years, and he has also seen all kinds of strange requirements of large families, including many of them to build secret grids and other shady things, and to build tools for various workshops, which is even more like a cow's hair. Although he couldn't figure out what Dr. Guozi, a noble doctor like Zhang Shou, was doing to make a textile machine, his years of experience told him to do more and ask less.

Therefore, he immediately said: "Compared to the two complicated big guys just now, this is very easy, at most ten days and half a month, I will definitely make a finished product that can be used." The springs to be used in these places, if the spring winding machine will not be able to do it for a while, I will draw the wire myself and wind it by hand! ”

At this moment, Zhang Shou heard a loud cough outside, and when he looked back, it was Lu Sanlang, who was shy and protruding, with a smile on his face: "Little sir, I just went to buy the blacksmith shop, do you want to take a look at it?" ”
