"Of course I want it..."

Meng Tian immediately laughed and said, "Isn't this just here to ask the sir for some advice?"

"Okay, then I'll say it."

Zhao Long said, "First of all, if we don't have electric monitoring, we can do manual monitoring, which is the earliest observation deck and observation post. If there are too many people, we can take turns to monitor it."

"Ha, this is..."

Meng Tian smiled and said, "And there are quite a few, but it's too late to see it..."

"Don't you have a phone number? If you find it, call quickly..."

Telephone?

"that……"

Meng Tian smiled, "I'm afraid... can't..."

"Damn it, that's a pity, but it may also be because of the bad local signal..."

That’s right, some pastures are close to the deep mountains and can easily have some magnetic field, which causes cell phone signals to fail.

For example, the expedition team that went to a certain place some time ago lost its ability to contact the outside world because of the magnetic field, so even if the mobile phone is brought in, it is directly equivalent to being scrapped.

"yes……"

Meng Tian also laughed, thinking that he could only find such an excuse.

"If the signal is not good, then you can only rely on simpler physical means."

Zhao Long said, "You can look back and buy some telescope observation mirrors. This thing can see a little further! It's much more useful than human eyes!"

oh?

telescope?

That is what this gentleman asked His Majesty to use last time?

Meng Tian felt a little moved after hearing this.

I thought to myself that if that thing was filled with the Great Wall, I wonder what effect would be?

He asked hurriedly, "Typeg? Is it the one that the sir showed to the village chief last time?"

"Haha, right...huh?"

Damn?

As he said that, Zhao Long was stunned by himself, and then he remembered.

"Where is my telescope? Alas? I seemed to have used it for Lao Zhao last time?"

Mamadi, he didn't seem to give it to me?

"Sir, what's wrong?"

"I remembered that last time I took a telescope. Why don't I go and find Lao Zhao immediately to come back for you."

Zhao Long stood up and said.

Damn?

Don't!

How dare I do this?

"Sir, let it go..."

Meng Tian quickly rubbed his hands with a smile, "It would be even better if the sir could make another one..."

"ah?"

Zhao Long was stunned and then said, "If I did it myself, if it was bigger, it would be difficult for you to take... By the way, how are you leaving? Take the train?"

"No, ride a horse..."

"You are brave enough to ride a horse..."

Zhao Long was surprised when he heard this.

"Haha, I'm used to it..."

"Hey, save money, right? It's all because we're used to being poor..."

Zhao Long sighed after hearing this, "Don't worry, when the national poverty alleviation task is promoted better, we will not lack the money for taking the train."

"Ah, yes, yes..."

"Why would I teach you a method, right? Even if I make one or two for you, it would be useless. After all, your ranch is so big!"

Zhao Long said.

"It would be even better if you teach the method!"

Meng Tian was even more excited when she heard this.

"It's not difficult, come and I'll draw one for you..."

Zhao Long said that, pushing his plan aside, then took a few pieces of paper to spread it, holding a charcoal pen in one hand and a wooden ruler in the other. While teaching, he said to Meng Tian, ​​"Actually, this telescope is simple."

To put it, it is just four lenses. If it is a more complicated observation lens, there will be six or eight lenses. You can make glass now, right?"

"Yes, glass can do it now..."

After all, Meng Tian has been influenced by her for so long and still understands the process of making glass.

"That's good."

Zhao Long said, "We don't need to make it if it is too fine. Then use simple methods to save trouble and money. After you make these lenses, the key is to polish the angle.

Make the glass thicker and rounder first. If possible, make an oval disk first, which is the most convenient way.

Then you use iron gauze. If not, just use thicker sand to grind it.

After the glasses are ground into a rough shape, you can assemble them. In fact, assembling is very simple. Remember to adjust the proportions in this order, and that's fine."

Zhao Long said, and had already drawn a rough idea, "How is it, isn't it difficult?"

"Tsk tsk, sir is worthy of being sir..."

After hearing this, Meng Tian looked at the sketches and couldn't help but sigh, "I never thought that such a magical thing was not difficult to make."

"It's not difficult. The key is whether you understand the structure inside it or not, and it's quite time-consuming."

Zhao Long smiled and said, "Overyone of us doesn't want to spend so much time or study more troublesome skills. In order to steal the laziness in front of us, we often deal with and fool around.

As for this person, dealing with and fooling is to others at the beginning, but if you keep doing this, you will deal with and fooling yourself.”

"Sir, this is reasonable."

"By the way, sir..."

Meng Tian hurriedly asked again, "How far can this thing be seen?"

He thought to himself that this question had to be asked clearly. If this thing could not see too far, it would not be of great effect for his own marching and observing the Huns.

Of course it is definitely better than the eyes!

It would be great if the observation distance could be relatively far!

"This...if you do it better, it is possible to look at five thousand meters, but we may not reach that..."

Zhao Long said with a smile, "But if you stay at your own observation post, you can do it. It is bigger and longer. As long as the weather is right and the focal length is adjusted well, even if the viewing is not particularly clear, the distance is not a problem! 2.

It can be seen ten thousand meters away!

If you carry this with you, I feel that it would be great to have a 3,000-meter-4,000-meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long meter-long

However, this also depends on whether the person who observes has good eyesight. If his eyesight is good, he will see farther and clearer. If his eyesight is not good, if you use good software to show him, he will also have to discount a lot of results!"

"That's true..."
