Just like many ordinary people, old guys don’t care about the principle of glasses. They use it as a standard for whether it is easy to use.

So although Old Man Kong kept explaining that this pair of glasses was only suitable for him, they were still spread by everyone until they finally passed on to someone's hands, and disappeared forever in this world and never appeared again.

If the old man Kong Yingda was not in his forties and almost fifty years old, he would be embarrassed, and he would probably sit on the ground and cry.

What a good pair of glasses, which saved him a lot of worries when looking at things at night. Although he still had a pair of lenses at home, he still felt very distressed.

For scholars, this thing is a magical tool. Ordinary people often ask for a pair but cannot get it. Now it is gone, how can they not feel distressed?

As the head of the "big boss", he disdained to take care of these trivial matters of Li Er. The glasses on the left and right were unrelated to Li Chengqian. At worst, he could ask him to solve them. A pair of glass pieces made so many things, it would be good if he didn't beat him up. What's the point of solving 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 record the degree of dizziness of each old man, and then arrange for the glass workshop to make convex lenses of different thicknesses.

Anyway, with Old Man Kong as a benchmark, lenses that are worse than him are thicker, and lenses that are lighter than him are thinner. This doesn't matter, anyway, the glasses do not have that high requirements for degree.

The ‘Master’ has been cooperating with Li Chengqian’s records. In the process of preparing various chemicals, this guy almost forgot his identity as a alchemist and was completely immersed in the ocean of science.

Li Chengqian arranged for him to record the eyesight of the old guys, and he was happy to accept that science is very interesting. Thin glass can actually ignite the paper. He wanted to know the reason.

So the "master" meticulously carried out the recording work, intending to perform better, and when he turned around and asked Li Chengqian for advice, he could have some confidence.

After a long time of struggle, I saved up a lot of small wooden strips and finally recorded the eyes of the old people in need. After I just had time to count them, I could ask the glass workshop to make lenses.

The prisoners of war had just been picked up by more than ten times, and were standing aside, looking at Li Er and others in a hurry. The first time they met the Emperor of Tang at such a close distance made them very nervous and made all kinds of guesses in their hearts.

However, their speculation did not take long, and one of them was dragged out of the crowd and tied to a tree. Then everyone retreated aside, leaving a large area around the unlucky guy.

The unlucky guy tied to the tree was frightened and looked at the sealed carriage that was getting closer and closer to him, and his face showed a terrified expression.

The carriage stopped five steps away from the unlucky guy. He turned the front of the car, aimed the rear of the car at him, then moved back and forth a few more times before stopping in place.

Unknown fear enveloped the unlucky guy tied to the tree. Adrenaline began to rush, his heartbeat suddenly accelerated, and cold sweats swooshed on his head...

The unlucky guy didn't know what he was afraid of. In short, he was very scared, but the more he was afraid, the faster his heart beat, and the more adrenaline he secreted. Finally... After a violent tremor, the unlucky guy had a frightened expression on his face and stopped breathing. He finally succeeded in scaring himself to death!

And 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 was about to cry without tears.

What's this? Can you kill someone by taking a photo? Who chose this guy on the tree? How could he get such a coward come out? Isn't it just tied to a tree and stayed for a while, and how could he be scared to death?

Unlike Li Chengqian, Li Er and others were even more sure that the photography car was a "big killing weapon". Everyone hid far away and refused to move closer to the car.

The photos are very clear, and the guy on the tree takes every move clearly, but this is even more certain, the fact that the photography car can absorb people's souls.

"Father, this is a coincidence. Really, if you believe me once, I will take a photo myself, there will be no problem. The boy just now was just too timid and was scared to death." Li Chengqian surrounded Lao Li and explained the principle of the photography car for the ninth time and its harmlessness.

Helplessly, Lao Li didn't listen to Li Chengqian's explanation at all. He just came together with a group of old killers such as Li Jing to study the feasibility of putting a photo car on the battlefield.

What can suck people's souls is the largest "killing weapon" in the Tang Dynasty. When you push it on the battlefield during a war, you will definitely force the enemy to die as much as you want, and lock all the damn enemies into that small piece of glass.

I took a camera to the front line and planned to take all the enemies to death. Who thought of this? Are you playing funny jokes?

Li Chengqian, who had no choice but to arrange for Ye Mei to choose someone, and this time he had to choose someone who was more courageous and would be rewarded with great profit. As long as anyone dared to stand behind the carriage for a quarter of an hour, he would immediately let him go, give his family the identity of a small Tang people, and also have a reward of ten cents of money.

As the saying goes, there must be a brave man under the rewards of the public. Li Chengqian's promise quickly got the answer that satisfies him. Three of the dozen Turkic prisoners of war were willing to give it a try.

Half an hour later, Li Chengqian was satisfied and announced to the three Turkic people who participated in the test that they had regained their freedom, and also arranged for people to give them ten coins of copper coins each.

After seeing the photos of the three people, Li Er and others finally stopped sticking to their initial views, but their attitude was still a little hesitant.

Seeing this situation, Li Chengqian simply invited Changsun Wuji to enter the carriage with him and started his nth photography work.

This time, when the photos were cleaned, Li Er and others finally believed it a little. They felt that the photography car seemed to be not as terrible as they thought, and they agreed to Li Chengqian's request for taking photos.

One, two, three, half an hour later, when Li Chengqian returned to Li Er with a bunch of photos taken by the "masters" for him, the old man finally couldn't help it and took the initiative to walk behind the motorcycle.

The great Emperor of Tang Dynasty finally overcame the fear in his heart under the temptation of more than twenty photos and took the first photo of his life on the seventh day of the fourth month of the fifth year of Zhenguan.

This photo provides a lot of historical basis for future archaeologists.

What does the Emperor of the Tang Dynasty look like, what is the Dragon Robe of the Emperor of the Tang Dynasty, and how spectacular the Emperor of the Tang Dynasty is...

Countless puzzles that have been unsolved in later generations have been engraved into this photo, waiting for future generations to discover!
