For binoculars, Wang Ke is also very eager to see, after all, these eyes look together, it is more comfortable than one eye, now seeing everyone asking for this, Wang Ke also thinks, even if it is a monocular now, if you want to improve to binoculars in the future, these words are also to be said, you have to say it early and late, and it doesn't hurt to say it now.

After figuring out this truth, Wang Ke also opened his mouth: "Actually, it's not a big problem, binoculars are nothing more than two monoculars together." However, there is a problem, because it is two sight tubes, to pull out one by one, it is a lot of trouble, that is, it is inconvenient to adjust the distance, so we need a linkage device, so that when we observe through the telescope, the eyes can never leave the telescope, only with the hand to turn a mechanism, you can adjust the distance before and after the sight glass. []”

Wang Ke really didn't know how to say it when he explained this, if he said what the focal length was normal, he would estimate why he had to be the focal length, and he had been explaining it for a long time, so he could only try to explain it in the language of the current era.

After Wang Ke finished speaking, he looked at the group of people in front of him, and he didn't know if they all understood, but he saw that the expressions of these people were different.

A group of old killers are at a loss, and they don't know what Wang Ke is talking about; Li Ke seemed to understand a little, but he definitely didn't run through, and was looking up and meditating there; Only a group of craftsmen seemed to understand Wang Ke's words thoroughly, and they all lowered their heads and thought there, and discussed a few words in a low voice from time to time. []

When Wang Ke saw such a scene, he didn't dare to say anything, so he asked Li Ke to ask these craftsmen to do things immediately, and he also thought that if these craftsmen could think of something, he would discuss it with them and go directly to the binoculars.

Wang Ke's wait did not disappoint him, and it didn't take long for someone in the craftsman to ask Wang Ke in an uncertain tone: "Lord Wang, what if you use the threaded rod used on the rear cannon support frame we are making now?" As long as the threaded rod is made small and the transmission device is added several times to control the forward and backward movement of the two eyepieces, it should be possible to make a small one. ”

These words made Wang Ke couldn't help but be shocked, why did he forget it, now Li Ke has developed a threaded rod here, and it has also been put into use.

In fact, the focal length adjustment of binoculars is also this principle, by rotating the threaded rod to make the screw move up and down to achieve the adjustment of the target distance, so that the focal length can adapt to the place you want to see more clearly.

Now what we have to do is that the thread of the screw is not fine enough, as long as it can meet the requirements, this problem can be solved, listen to the tone of this craftsman, the problem of this screw is no longer a problem, then in this way, there will be no obstacles to making this binoculars!

Wang Ke looked at the craftsman with some surprise, suppressed the 'agitation' in his heart and asked, "Have you solved the problem of this screw now?" If that's the case, then what are you waiting for, hurry up and do it! ”

For Wang Ke's words, these craftsmen also know that it is equivalent to Li Ke saying to them, and sometimes it is even more effective than Li Ke's words, because they have all seen it, and even Li Ke has to abide by what Wang Ke sometimes says, and now Wang Ke has spoken, and without waiting for Li Ke to speak, they disperse in a hurry, and each of them goes to prepare what they should do.

At this time, Li Ke had already reacted, and when Wang Ke explained the problem just now, he didn't understand it very well, but now when he heard the words of the craftsman, he also understood it thoroughly, and his face was smiling like a 'flower'. []

But at this time, Wang Ke couldn't stay here, he had to rush back to his own village, when he came over today, he just brought a piece of glass of each size, and now he wants to make binoculars, this glass lens is not enough, if he doesn't go back to the village to get it, even if the shell of the telescope is made, there is no lens to install it.

Wang Ke looked at the group of old killers standing behind him, and said to Li Jing with a smile: "Uncle, the little nephew is going back to the glass workshop to get the lenses now, I wonder if the uncles are interested in going together to see the glass making process?" ”

Wang Ke said that this has a meaning, and now this is just another preparation, this gang of old killers can't see anything here, if they can't see things come out all the time, these old killers are in a hurry, and they don't scold these craftsmen for being bloody, if these craftsmen have a bad psychological quality, they are scolded by these old killers, and they can't do anything in a panic.

And if you coax these old killers to yourself, anyway, glass making is already a familiar way, and they are not afraid of what they haven't seen in the past.

Today, these old killers came to see the excitement, but now they don't see it here, and it's not bad to go to Wang Ke to see the glass production, so there is no need to discuss, and as soon as Wang Ke finishes speaking, they all turn around and go outside.

Wang Ke watched Li Ke also follow the old killers to the outside, grabbed him and asked, "Where are you going?" You've got to stay here. We'll be back in a minute, and you'll have to keep an eye on them. ”

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Li Ke looked at Wang Ke, rolled his eyes and said, "What can I stare at here?" They know more about these things than I do, and I'm not in the way of staring here! Why don't I go with you and see how this glass is made? Didn't you say you'd be back in a while? You come back and look so much better than I look here! ”

Wang Ke was choked by Li Ke, and he really couldn't say anything, what Li Ke said was crooked, and there was a little bit of reason, Wang Ke could only feel that Li Ke followed him, and he didn't learn anything else, but he learned decently.

Wang Ke had no choice but to wave his hand helplessly and carry a group of people to the glass workshop in Zhuangzi.

The arrival of an old killer also frightened the craftsmen in the glass workshop, they came to Wangjiazhuang, and the Tang soldiers they saw were Wang Ke alone, Li Ke came once, but he didn't see it, he just walked in a hurry, pulled Wang Ke and ran, it is estimated that these workers did not even see clearly.

Now there are six or seven of them, except for one whose epaulette looks lower than Wang Ke, and the others are all higher than Wang Ke, this is not a joke, for these craftsmen, who has ever seen such a big official, now let them see so much, it is inevitable that they will panic for a while.

For Li Ke, these craftsmen really didn't pay attention to it, for them, Wang Ke's military rank is higher than Li Ke, I don't know anything else, the beans on this shoulder can be counted, Wang Ke is three, Li Ke is only two, so when these craftsmen saluted to the old man, they just bent down to Li Ke simply, and they were all busy with their own work, and they didn't even look at Li Ke.

Wang Ke saw all this in his eyes, knowing that this was all because Li Ke's current military rank was not as high as his own, plus these craftsmen didn't know Li Ke's reason, if they knew Li Ke's identity, even if Li Ke was wearing soldiers' clothes, it was estimated that the attitude of these craftsmen would not be like this, and they would definitely be more respectful than those old killers.

Li Ke didn't care about these, one is that he is very easy-going on weekdays, and he only thinks about his identity when he needs to use it, and the other is that everything now is so novel in his eyes, where is there time to think about what attitude these craftsmen have towards him.

Wang Ke originally wanted to directly find two craftsmen who can polish lenses, to see how many lenses they have polished there now, and take as many as they want, anyway, for Wang Ke now, that is, to do an experiment, first 'get' a sample, to see if it can be used, and then to plan the process and carry out large-scale production. []

But Wang Ke only found out at this time that there was one less in this group of craftsmen, it was Lapde who told him that the one with the best polished lenses, Wang Ke hurriedly called Lapde and asked what was going on, and after Lapde's explanation, Wang Ke understood that this was all arranged by Lapde.

Now it's not the same as before, now not only have to make glass, but also polish the made glass, they don't know when Wang Ke needs it, how much he needs at a time, they can only keep making it.

Lapde feels that several craftsmen are making glass here now, and the matter of grinding lenses has to wait until their free time to do it, so that one is not very fair to the craftsmen who polish lenses, and the other is that there is less time to polish lenses, if Wang Ke says that he needs it, he is afraid that he will not be able to take out so much at once, so he simply let the craftsman concentrate on grinding lenses next door alone, and there is no need to come here to make glass. Later, when everything has been learned, there will be another division of labor.

After listening to Lapde's explanation, Wang Ke's heart relaxed, he thought that something had happened, but it turned out to be the case, and now that Lapde has such a division of labor, this efficiency has to be improved a lot.

Wang Ke looked at a group of old killers and Wang Ke were watching the craftsmen make glass with great interest, and did not greet them, he came to the room next to him, for the production of glass, Wang Ke is not much interested now, now he only cares about whether this telescope can be made, if it can be made, he will immediately throw it to Li Ke, he still has a lot of things to do, how can he delay so long in one thing.

Seeing Wang Ke coming in, the craftsman who was polishing the lenses immediately stood up and said to Wang Ke with a smile: "My lord, three pairs have been polished, you can ask for it whenever you want." ”

Wang Ke nodded and said, "Then give it to me first, now I just need to make samples." You continue to be yours, and I'll take it and go. ”

Hearing Wang Ke say this, the craftsman immediately took out the lenses from the small box where the lenses were placed, and carefully 'handed them over' to Wang Ke, who carefully checked them and felt that there was no problem, nodded to the craftsman, and withdrew.

Walking back to the glass workshop, Wang Ke smiled and said loudly to the old killer and Li Ke: "How is it, have you finished reading it, should Your Highness and a few uncles go!" ”

A few old killers originally wanted to see it again, but they still thought about returning to the Weapons Preparation Bureau to see the production of the telescope shell, so they didn't delay any longer, and they all walked out together, leaving only a group of craftsmen who heard Wang Ke call Li Ke there in a daze.

Only now did they know that the person they looked down on the most just now was actually the son of the Emperor of the Tang Dynasty, if his actions just now made His Highness a little unhappy, and he wanted to deal with himself, then maybe he would have been in the cell waiting for dinner.

All the craftsmen secretly made up their minds in their hearts, if Li Ke came over next time, they would have to be careful to 'wait', don't move their heads when the time comes, they don't know what's going on.

When Wang Ke and his entourage returned to the Weapon Preparation Bureau, they saw a group of craftsmen standing there, all of them with a depressed look on their faces, and the hearts of the group suddenly rose to their throats.

If that's the case, then this matter will be a little troublesome today!
