Like many ordinary people, the old guys don't care what the principle of glasses is, they are based on whether they are easy to use or not.

Therefore, although Old Man Kong kept explaining that this pair of glasses was only suitable for himself, it was still passed around by everyone, until finally he disappeared from this world forever and never appeared again.

If the old man Kong Yingda was not in his forties and almost fifty years old, he would be really embarrassed, and it is estimated that he would probably sit on the ground and cry at this time.

What a good pair of glasses, let him see things at night and save a lot of worry, although there is still a pair of lenses at home, but he is still very distressed.

For readers, this thing is an artifact, ordinary people often ask for a pair but can't get it, and now it's gone, how can you not feel distressed.

Li Er, as the head of the house, is the 'big boss' He disdains to take care of these trivial things, and the glasses on the left and right can't get rid of Li Chengqian, so let him solve it, a small pair of glass pieces has done so many things, it's not bad if you don't beat him, what is it to solve a small problem.

Therefore, during the period of waiting for the prisoners of war, Li Chengqian had one more thing, he had to use countless small wooden strips to write down the degree of dazzle of each old man, and then arrange for a glass workshop to make convex lenses of different thicknesses.

Anyway, there is an old man with holes as a benchmark, and the lenses that are more serious than him are made thicker, and the lenses that are lighter than him are thinner, it doesn't matter, anyway, the prescription requirements for the glasses are not so high.

The 'master' has been cooperating with Li Chengqian's records, and in the process of preparing various chemicals, this guy has almost forgotten his identity as a priest, and is completely immersed in the ocean of science and cannot extricate himself.

Li Chengqian arranged for him to record the eyesight of the old guys, and he was happy to accept it, science is such a thing as very interesting, thin glass can actually ignite paper, he wants to know the reason.

So the 'master' meticulously carried out the recording work, planning to perform better, and when he turned back to ask Li Chengqian for advice, he could also have some confidence.

After tossing for a long time, the small wooden strips saved a lot of money, and finally recorded the eyesight of the old goods in need, and after they had time to count them, they could let the glass workshop make lenses.

The prisoners of war had just been brought back by a dozen or so people, and now they were standing aside, looking at Li Er and the others with a shrunken look, the first time they saw the Tang Emperor at such a close distance, which made them very nervous, and they made all kinds of guesses in their hearts.

Their guess didn't last long, though, as one of them was dragged out of the crowd and tied to a tree, and everyone stepped aside, leaving a space for the boss around the hapless man.

The unlucky bastard, tied to a tree, was frightened and looked at the sealed carriage that was getting closer and closer to him, with a frightened expression on his face.

The carriage stopped five paces away from the unlucky man, turned around, aimed the rear of the carriage at him, and then moved back and forth a few more times before coming to a halt.

The fear of the unknown enveloped the unfortunate man tied to the tree, the adrenaline began to rush, the speed of his heart beat sharply, and the cold sweat 'swished' on his head .......

The unlucky guy didn't know what he was afraid of, in short, he was scared, but the more he was afraid, the faster his heart beat and the more adrenaline he secreted, and finally ...... After a violent trembling, the unlucky guy stopped breathing with a frightened expression on his face, and he finally managed to scare himself to death!

At this moment, Li Chengqian also walked out of the carriage with a photo.

Coincidence, damn coincidence, shaking the photo in his hand, Li Chengqian wanted to cry without tears.

What's this special thing called, taking a picture can kill people? Who picked this guy in the tree? How could such a coward come out? Isn't it just tied to a tree for a while, how can you be scared to death?

Unlike Li Chengqian, Li Er and the others were even more sure that the camera car was a 'big killer', and everyone hid far away, resolutely refusing to take a step closer to the car.

The photo is clear, and the guy's every move in the tree is clear, but it also makes it more certain that the camera car can suck people's souls.

"Father, this is a coincidence, really, you believe me once, I will take it in person, it must be no problem, that kid just now was just too timid and was scared to death." Li Chengqian surrounded Lao Li and explained the principle of the camera car for the Nth time and its harmlessness.

Helplessly, Lao Li didn't listen to Li Chengqian's explanation at all, and only got together with Li Jing and a group of other old killers to study the feasibility of putting the camera car on the battlefield.

The thing that can suck people's souls is the biggest 'killing weapon' in Datang, when it is fighting, it pushes it on the battlefield, and it forces the enemy to die as many as he wants, and all those damned enemies are specially locked in that small glass.

Who came up with the idea of getting a camera to the front line and trying to shoot the enemy to death? Funny jokes?

Li Chengqian, who had no recruitment, could only arrange for Ye Mei to choose someone again, and this time he had to choose someone who was bolder, and promised heavy profits. As long as anyone dares to stand behind the carriage for a quarter of an hour, he will be set free immediately, and he will be given the status of a small Tang citizen of his family, and at the same time there will be a reward of ten yuan.

Li Chengqian's promise was quickly answered to his satisfaction, and three out of a dozen Turkic prisoners of war were willing to give it a try.

Half an hour later, Li Chengqian was satisfied with announcing to the three Turks who had taken part in the test that they had regained their freedom, and at the same time arranged for someone to give each of them ten copper coins.

And after Li Er and the others looked at the photos of the three people, they finally stopped insisting on the point of view at the beginning, but their attitude was still a little hesitant.

Seeing this situation, Li Chengqian simply invited the eldest grandson Wuji to enter the carriage with him and started the Nth photo work.

This time, when the photo was cleaned out, Li Ercai and the others finally believed it, feeling that the camera car really didn't seem to be as terrible as they imagined, and agreed to Li Chengqian's request to take pictures.

One, two, three, when Li Chengqian returned to Li Er with a large number of photos taken by the 'master' for him half an hour later, the old man finally couldn't help it and took the initiative to walk to the back of the locomotive.

His Majesty, the great Emperor of the Tang Dynasty, was tempted by more than 20 photos, and finally overcame the fear in his heart, and took the first photo of his life on the seventh day of the fourth month of the fifth year of Zhenguan.

This photograph provides a lot of historical evidence for future archaeologists.

What does the Tang Emperor look like, what is the dragon robe of the Tang Emperor, and how spectacular ...... the Tang Palace is.

Countless mysteries that have been unsolved in the future have been carved into this photo, just waiting for future generations to discover!
