Hard work pays off.

Thanks to their unremitting efforts, the world's first monoculars appeared nearly 1,000 years ahead of schedule.

The whole body of the lens tube is made of brass, which is similar to the appearance in later film and television dramas, it is made according to that look, and it is strange if it is different.

Ancient craftsmen really didn't build it.

A round copper tube, the surface is polished to reflect light, and the lens is also very strong, and it will not break if it is occasionally dropped.

Of course, there are many falls, but I dare not guarantee it, after all, the glass is brittle, and now it is only ordinary glass that is burned, which is fragile!

However, no one is going to sit idle......

In fact, the coppersmith also planned to carve on it, but Fang Yiai didn't let it in a hurry, and the other party complained a little, thinking it was too rough.

Fang Yiai was speechless for a while.

Is this still crude? Judging by their requirements, they are completely going for the artwork. In a dynasty without mechanization, it was a very high skill to be able to do this.

Really, these are the words of his heart, and he admires them in his heart.

This kind of craftsmanship is not to be said!

He doesn't pay attention to so much, the things used on the battlefield, don't talk about those bells and whistles, no matter how beautifully it is done, it is useless, practicality and durability are the most important.

The whole telescope is in the hand, heavy, very weighty, Fang Yiai tried it, the effect is also good, the bird's nest thousands of kilometers away, you can see it clearly.

"Master, let me see ......"

Fang Yiai's side, the little fat man Li Tai looked at it and couldn't wait to urge.

After Fang Yiai explained the principle, the little fat man knew what he was doing, and he also tried it during the experiment and experienced the feeling of clairvoyance.

At that time, I was really shocked by the magic of this telescope, which can be called a miraculous skill! I played with two lenses for a long time.

Now, his mood has calmed down a lot, his heart is prepared, and he is not as excited as before, but he is eager to try what the finished product will look like.

After all, it is the result of their own efforts, and countless hard work and sweat are condensed in it.

Look at my current appearance, his skin is dark like an old peasant, he has lost a lot of weight, and his neck is still molting, all of which is caused by looking at his glasses.

However, as soon as the telescope was built, it was first delivered to Fang Yiai.

He waited next to him for a long time, Fang Yiai looked east and west, but he didn't change him to play, and the little fat man waited impatiently before urging.

At this time, Susan brought Xiaohuan and Qiao'er in with tea, and when she saw the rare things in Fang Yiai's hands, she couldn't help but ask curiously: "Xianggong, what is this?" ”

"This is the telescope, the effect is not bad, the lady come and try it?"

"It's made!"

Fang Yiai and Li Tai said that Susan had heard about it for a long time, but it was the first time to see the finished product, and she was already curious in her heart.

Soon, Susan's exclamation was heard, startled, "Ah! That's a school under construction! I can actually see the top of the mountain,"

"It's amazing!"

Susan looked back at him, her eyes shining with countless little stars and a lot of love.

"I'll see it too."

Xiaohuan is still a little restrained, Qiao'er has been following Fang Yiai's side, understanding who the young master is, and developing an innocent temperament, shouting and coming up.

"I didn't expect to be able to see so far!"

Susan smiled and handed it over, and the three girls held binoculars and chattered and discussed, and even Fang Yi's love was squeezed out by them.

"Gotcha! I don't have to look at it now. ”

Li Tai thought desolate in his heart that he would not be able to take his turn until their excitement had passed.

"Anyway, I've already seen it when I was experimenting."

The little fat man comforted himself in his heart, and that was the only way. At this time, Fang Yiai remembered him, turned around and asked Li Tai, "Qingque, why did you say just now?" ”

"Heart-piercing! Master! ”

The heart that has just been healed a little through self-consolation seems to have been torn apart again, and it is dripping with blood! The little fat man has no love on his face.

You can hear what the master said, but my words were taken as a deaf ear, and it was only at this time that I remembered it, what is the meaning.

Do you want to be treated differently by Master?

"Nothing!"

Li Tai replied in disbelief that he was not in the mood to eat dog food, so he left alone and went to the corner to lick his wounds.

……

The next day, Cheng Fu.

Sure enough, the telescope sent by Fang Yiai was cut off by Cheng Yanjin halfway.

"What is this?"

Through Fang Yiai's consistent performance, although Lao Cheng said this, he attached great importance to what he had drummed up, and looked at the copper pipe carefully.

"Fang Er, this is your gift to me? What's the use? Cheng asked silently.

He is not disgusted, he can only say that the greater the hope, the greater the disappointment! He had been looking forward to the gift of Fang Yuai, thinking that he would give something powerful.

I didn't expect ...... It's a copper tube that doesn't see any use.

"It's called a telescope, and it can see everything from a kilometer away." As he spoke, Fang Yiai brought the telescope, "You come with me." ”

Fang Yiai took the lead, ordered the family to bring a ladder, and climbed to the roof without saying a word.

There is no way, there are many high walls in Chang'an City, and you can't see anything in the courtyard at all, so you can see farther from the roof.

Lao Cheng's father and son, who have never been the masters of Ansheng, have nothing to hesitate about, and then climbed up, he put the telescope in front of Lao Cheng's eyes, "Uncle Cheng, you close one eye and look." ”

Lao Cheng's left and right eyes squeezed for a long time, but he didn't know which eye to close, and finally simply covered it with his hand, his eyes were as big as copper bells, and he went up to look at it suspiciously.

"That's ...... Palace gate? ”

Looking at the image in front of him, the palace gate seemed to be close in front of him, and Lao Cheng asked in disbelief.

As if he had seen a ghost, he snatched the telescope and looked at it with the naked eye, only to see a faint shadow.

Chengfu and the palace gate are only one street apart, but at least a few thousand meters, and then raise the binoculars, even the soldiers on the city wall can clearly see.

Cheng bit Jin Rongma all his life, unlike Susan and the three of them, who just regarded it as a toy and immediately thought of military use.

How important "intelligence" is to the war, he knows in his heart!

If he goes to the battlefield and has this telescope in his hand, he can see the enemy, but the enemy cannot see himself, which will have a natural advantage, and often determine the victory or defeat of this war!

Seeing his father's reaction, Cheng Chumo also put away his contempt, knowing that although this guy was small, it was by no means simple, and he also looked at the telescope, hoping that Lao Cheng would show himself after reading it.

"This is no small thing!"

Cheng Yanjin was shocked in his heart, and immediately made a decision, "Go!" Enter the palace! ”

Carefully put away the binoculars, ignoring Cheng Chu's silent and complaining eyes, he took the lead and went to the roof and led the two to the palace.
