Deconstruction is Weird

There are roughly three ways to make a mirror, one is tin amalgam, stick a layer of tinfoil on the back of the glass, and then sprinkle mercury, the mercury will melt the tinfoil, thus covering it with a layer of silver film, but this method has been eliminated.

In modern times, there are probably only two methods commonly used, aluminum mirror and silver mirror reaction. The former uses aluminum to evaporate and adhere to the glass to form a mirror surface. The effect is excellent.

But comparing the two, aluminum mirrors are cheaper.

Chu Dong tried both methods, but the effect of the aluminum mirror was not very good, because he could not find a suitable evaporation environment. The ideal environment would be a vacuum, and the effect of the mirror made was mediocre, so Chu Dong could only use the silver mirror. reacted.

This procrastination took another three days, but Chu Dong's mirrors were finally made, a total of 1,000 yuan per square meter of square mirrors, and some iron frames were specially made to fix the mirrors, and then Chu Dong Dong spent another day transporting these things to the mountain walls on both sides of the Moragan Canyon. Zhinao drew a total of two best reflection points, and the closest distance was at noon when there was plenty of sunlight.

Chu Dong directed the craftsmen to splice the mirrors together with iron frames, making ten concave mirrors with a height of seven meters. Each concave mirror cost a hundred mirrors. The angle was calculated by the brain, and it just fit into the canyon. Center, but also can make some fine-tuning according to the time.

This commotion was too loud, and it attracted the members of the Miao family. When they saw a mirror that revealed everything, everyone behaved differently. Li Hongxian just thought that Chu Dong was quite capable and had a good brain.

Lan Gu and Miao Wenjiu were more embarrassed, saying that they wanted a piece, it would be much more convenient for daily dressing, and it was much easier to use than the bronze mirror they used.

Chu Dong said with a smile: "Two aunts, don't be in a hurry. Give this to the Miao family when you run out. Is one thousand yuan enough? If it's not enough, I'll make it."

Lan Gu said with some embarrassment: "This, this is not suitable, it is a bit too expensive."

Zhang Han was not very interested in this kind of handicraft. At first he thought that Chu Dong was going to make a magic weapon, and thought that he had learned the Fang family's soul refining technique, but it turned out to be an ordinary mirror. Although it was indeed very precious, that After all, it is the object of ordinary people.

Near noon, Chu Dong waved the flag in his hand towards the opposite side of the valley, and Yang Yiqing also waved the flag on the opposite side to show that he had seen it. The two were standing at the corners of their eyes, about two kilometers apart, and the time was right. Pulled off the black cloth covering the mirror.

The next moment several people were stunned, and Zhang Han even flew directly to the side of the mirror to observe carefully. A total of ten concave mirrors spliced ​​together shot out ten strong lights into the canyon. The black mist surged, as if there was some violent reaction, and the figure moved as if struggling with something, which looked very painful.

These ten rays of light are still not enough, but they are really weakening the concentration of the Kuroshio in the valley. The most important thing is that it is effortless, as long as there is the sun.

Chu Dong squatted on the edge of the cliff and observed for ten minutes. According to the rate of reduction, it would take half a month. However, this indeed proved the conjecture of the brain. The sunlight has some special reactions with these black currents, but it is not dark energy. Neutralization is still unknown.

Seeing that the mirrors were still not enough, Chu Dong could only go back and continue to work. He taught Li Hongxian how to adjust the angle. As a result, Li Hongxian just lifted up his concave mirror, which was composed of a hundred mirrors and an iron frame. Winter steering gear.

Li Hongxian suddenly realized: "I seem to have played with this when I was young. When I was young, I often used bronze mirrors to look at people, and my father beat me often. It's because the light reflected by your mirror is so strong."

"Take it easy, this mirror will break if you touch it, it's not as strong as a bronze mirror, if it breaks, my seven days of hard work will be in vain."

In order to make these mirrors strong, Chu Dong smeared a layer of clay on the back of the mirrors, and it was baked at a high temperature, which is easy to transport and not easy to break, but it will be heavy like this, and the iron frame will be added soon, It was estimated to be three to four hundred catties, and Li Hongxian's strength was still a bit outrageous.

The method was effective, so Chu Dong ordered the factory to continue to make it. He did not tell anyone about the ratio and silver mirror reaction. This is the core technology, and it is impossible to fake it by others. She went to silver plating and broke several pieces for you in minutes.

The scale of the kiln and the production speed of the mirrors are also much faster. Five hundred yuan can be produced in a day. One concave mirror after another is set up on the cliffs on both sides of the canyon. Protection, for fear that someone will destroy it.

Chu Dong spends an hour every day in the valley to collect data and record the changes. There are too many desires in the black mist, and they can see their struggles outside, but the struggles have no effect. Bright light destroys them every day.

Another three days, the gate of hell has been exposed to the sun for three days and has completely lost the mystery of the past. The black mist is almost gone. With the light of the mirror, they can see the scene in the valley clearly.

There is actually a bronze door in the center of the canyon, eight meters high and three meters wide, but the door is embedded in the ground, and there are some things carved on the door that are too far away for Chu Dong to see, so the few people meet today Explore the gates of hell again.

Zhang Lingwei and Yang Yiqing were left behind. They needed to adjust the angle of the mirror as the sun changed, trying to let the sun shine around Chu Dong and them. The people who designed this place probably would not have thought that someone could attract sunlight from the outside. This barrier, which is fatal to humans, was dealt with so easily.

The few people did not encounter any strange things when they entered the canyon this time. Although the valley was gloomy, there was no foreign object. They came all the way to the center of the canyon before the bronze gate. The ground is so smooth it's unbelievable. It's close to metal.

Chu Dong touched the smooth ground and exclaimed: "This ground is unbelievable, isn't the technology of Yunshang Kingdom too developed in that era?"

Several people turned around, and there was nothing else but this door, it was empty.

Only a token was found on that door, and two porcelain vases.

Chu Dong was startled when he saw the token, because he had one of the tokens, which was left to him by Huang De, but the two tokens had the same side, so they couldn't be made into a pair. A pair of front and back cards should be more effective when put together. Why is there only one side?
