Deconstruction Weird

There are about three ways to make a mirror. One is tin amalgam. Paste a layer of tin foil on the back of the glass, and then sprinkle it with mercury. The mercury will melt the tin foil and add a silver film to it, 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 evaporation to attach to the glass to form a mirror surface, the other is to use the silver mirror reaction to replace the silver ions with a solution to allow the silver ions to adhere evenly. The effect is excellent.

But comparing the two, aluminum is cheaper.

Chu Dong tried both methods, but the effect of the aluminum environment was not very good. Because the ideal environment should be vacuum, the ideal environment should be vacuum, so the mirror effect was average, so Chu Dong could only use the silver mirror. reacted.

This drag took another three days, but Chu Dong's mirrors were finally made, a total of 1,000 square meters of square mirrors, and some artificial iron frames were used to fix the mirrors. Then Chu In another day, Dong transported all these things to the mountain walls on both sides of the Moracan Canyon. Zhi Brain drew a total of two best reflection points, and the nearest sun was at noon.

Chu Dong commanded the craftsman to splice the mirrors together with an iron frame to make a total of ten concave mirrors up to seven meters high. Each concave mirror consumes a hundred mirrors. This angle has been calculated by the brain, and it can be shot into the canyon. Central, but also can make some fine-tuning according to time.

The movement was so loud that it attracted all the Miao family members. When they saw a delicate mirror, everyone behaved differently. Li Hongxian just thought that Chu Dong was quite capable and had a good mind.

Lan Gu and Miao Wenjiu were more embarrassed. They said they wanted a piece of it. It would be much more convenient for dressing on weekdays. It was much easier to use than the bronze mirrors they used.

Chu Dong said with a smile, "Don't worry about the two aunts. Give them to the Miao family when you run out. Is one thousand yuan enough? I'll do it if it's not enough."

Gu Lan said embarrassedly: "This, this is not appropriate, it's a bit too expensive."

Zhang Han is not very cold with this kind of handicraft. At first he thought that Chu Dong was going to be some kind of magical instrument. He also thought that he had learned the soul refining technique of the Fang family, but the result was an ordinary mirror. Although it is indeed very precious, that After all, it is an object of ordinary people.

Approaching noon, Chu Dong waved the flag in front of the valley. Yang Yiqing also waved the flag on the opposite side to indicate that he had seen it. The two people stood at the corner of their eyes, about two kilometers apart. Pulled off the black cloth covering the mirror.

The next moment everyone was stunned. Zhang Han even flew directly to the mirror to observe carefully. A total of ten spliced ​​concave mirrors projected ten strong rays of light into the canyon. The black mist surged, as if a violent reaction was taking place, and the figure moved as if there was something struggling again, and it looked very painful.

These ten lights are still not enough, but it is really weakening the concentration of the Kuroshio in the valley. The most important thing is that it is effortless and the sun will do.

Chu Dong squatted on the edge of the cliff and observed for ten minutes. According to this rate of reduction, it was estimated that it would take one and a half months to shoot, but this did prove the wisdom brain’s conjecture that sunlight had some special reactions with these dark tides, but it was not dark energy. The neutralization is still unknown.

Seeing the mirror was not enough. Chu Dong could only go back and continue to do it. He taught Li Hongxian how to adjust the angle. As a result, Li Hongxian stunned him to lift up his concave mirror composed of a hundred mirrors and an iron frame. There was no need for Chu. Dong's steering gear.

Li Hongxian suddenly realized: "This seems to have played with me when I was young. When I was young, I often used bronze mirrors to illuminate people, and I was often beaten by my dad. It's just that the light reflected by your mirror is so strong."

"You can take your time. This mirror breaks when you touch it. It is 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 applied a layer of clay on the back of the mirrors, and after high-temperature baking, it is easy to transport and not easy to break. It will be very heavy. Estimated to be three to four hundred catties, Li Hongxian's strength is still a bit outrageous.

The method worked, and Chu Dong ordered the factory to continue. The matching and the silver mirror reaction he did not tell anyone that this is the core technology, and it is impossible to use others. He has the heart to teach Yang Yiqing, but Yang Yiqing... , I really asked her to go to the silver plate to break a few pieces for you in minutes.

The kiln has become large, and the production of mirrors has been much faster. It can produce 500 yuan a day. On the cliffs on both sides of the canyon, there are one concave mirror after another. Li Hongxian and Zhang Han are on each side. Protection is afraid that someone will destroy it.

On the other hand, Chu Dong set aside one hour a day to collect data in the valley and record the changes. There are too many desires in the black mist, and they can see their struggle outside, but the struggle has no effect. This The bright light destroys them every day.

It was another three days. The gate of The Underworld had been exposed to the sun for three days and had completely lost the mysteriousness of the past. The black mist was almost scattered. With the light beam of the mirror, they could see the scene in the valley clearly.

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

Zhang Lingwei and Yang Yiqing were left behind. They need to adjust the angle of the mirrors as the sun changes, and try to let the sun shine around Chu Dong. The people who designed this place at the beginning would not have thought that anyone could attract sunlight from the outside. This barrier that was fatal to humans was so easily dealt with.

This time the few people reentered the canyon without encountering any strange things. Although there was no foreign matter in the canyon, they came all the way to the center of the canyon and before they came to the bronze gate. The ground is so smooth and flat that people can't believe it. It's close to metal.

Chu Dong touched the smooth ground and exclaimed, "This ground is incredible, isn't the technology of Yunshangguo's era too advanced?"

A few people circled around, there was nothing but this door here, it was empty.

Only a token and two porcelain vases were found on the door.

Chu Dong was shocked when he saw that token, because he had one of this token, which was left to him by Huang De, but the two tokens were the same, so they couldn't make a pair. The pros and cons of the cards are in pairs, and they should have a greater effect when put together. Why is there only one side?
