Datang Lingnan King

Chapter 185 Microscopic World
Since Feng Daiwen said to make a magnifying glass, he rushed to Zhujiazhuang the next day so that the craftsmen could do it according to his requirements.

Zhujiazhuang was the same as before, but it was more prosperous. Many horse-drawn carriages came to transport goods, and many houses in the village were enlarged. Villagers who knew each other came to salute Feng Daiwen and expressed their sincere thanks.

The fish pond started to be built in summer is also built around the foot of the mountain. The whole stone mountain seems to be an isolated island, located in the middle of the fish pond.

Feng Daiwen walked all the way, watched all the way, Zhujiazhuang has completely become a breeding base, thousands of geese and ducks in the river are swimming in the winter water without fear of the cold, and countless chickens are leisurely in the farmland after harvest. foraging.

There is a pen next to every house in the villagers, in which pigs and sheep are raised, and the sound of cattle and horses echoes in the village from time to time.

Although Zhujiazhuang has become very noisy, and the sounds of animals are everywhere, but in the ears of the villagers, these are the sounds of nature.

Feng Daiwen came to the colored glaze workshop, found the old Taoist Qingyun, and told him his requirements. As a result, the old Taoist was so excited when he heard that he wanted to be a clairvoyant to see the moon.

Originally, the most important thing about Liuli is transparency, which is more difficult to deal with, but since there are a group of crazy Taoist priests, there is nothing they can't do.

In the past, they didn't realize that there is more and more interesting thing in this world than alchemy. Later, they followed Feng Daiwen to see saltpeter making ice. Stones can be turned into all kinds of glass, and then they can be made into mirrors that can clearly see people's shadows. Petroleum can be turned into coal. , The bark can also make snow-white paper, and after the limestone is burned, it can make cement, which can make the wall hard and smooth.

Since then, this group of Taoist priests have gone completely crazy. Any ore should be burned first. After one kind of ore is burned, another kind of ore is burned, and another kind of ore is burned together, in the hope of discovering something more magical.

And now the ore is provided by the government, and there are all kinds of them, which naturally makes them even more crazy. The furnace used for the experiment has almost never stopped. Fortunately, Feng Daiwen strongly requested that every experiment be recorded in detail.

Until one time when lead ore was added to the glaze firing process, it was discovered that the glaze produced not only had fewer bubbles, but was also more transparent, so this problem was also solved.

Both the magnifying glass and the telescope are concave-convex mirrors. This is just a mold problem, which can be easily solved. They were not allowed to make it before because the quality did not meet the requirements, and it was also for the sake of confidentiality. Now that it is under control, of course it can be made.

More than 20 moulds, big and small, of different thicknesses, were made. The largest one was made one foot three, and the thickest one was as thick as an adult’s fist. The furnace was opened, and the water made by burning ore was poured in, solidified, and cooled naturally. hour.

Feng Daiwen held the largest and thickest piece. Unfortunately, Feng Daiwen didn't know its size or its multiple, so he asked someone to make a copper tube with a large front and a small rear. It is composed of more than ten sections, and can be combined with different convex mirrors.

Copper is very soft and has a low melting point. Several skilled craftsmen made it quickly. The copper pipes are not only tightly fitted, but also polished very smooth without any burrs. People who are called ancestral blacksmiths are ashamed that such skills have disappeared in later generations.

Putting aside the entanglements in their hearts, the two of them led Qingyun Laodao to observe various things with large and small magnifying glasses.

"Wow! The old man was scared to death." Before Feng Daiwen could think about what to look at, the old man Qingyun screamed in fright.

"What's wrong?" Feng Daiwen didn't know what he saw, but he jumped up in fright, and even patted his chest in shock.

Old Daoist Qingyun smiled awkwardly, and said embarrassedly: "Just now the old Daoist saw a spider here, and just wanted to see what it looks like when zoomed in."

Feng Daiwen thought about it, shook his head with a smile, went to find the target to observe, and reminded Qingyun: "Remember, don't look at the sun, or you will be blind, so don't blame me for not predicting."

"Why?" Qingyun asked Feng Daiwen, blinking his eyes in confusion, maybe he was planning to find some time to observe the sun.

Feng Daiwen had no choice but to find a dead leaf and conduct a small experiment for him in the sunlight.

"This, this can actually start a fire out of thin air?" Qingyun old man was stunned once.

Feng Daiwen shook his head speechlessly, and explained carefully: "This is how to make a fire out of thin air. You haven't seen the magnifying glass in my hand. This is the principle of light concentrating. The sun's light has temperature. Gathering the light together can produce a very high temperature. temperature."

"It turns out that it is like this. The Tao Te Ching says that the way of nature is indeed the most powerful." Qingyun old man murmured.

"That's right, the power of nature is the greatest. If we learn to borrow it, we can become very powerful, just like the sunlight. As long as we study it, we can find many great magical effects, just like flowing water. Chang'an has already done it. The huge mill that comes out to use the water flow can grind out a thousand catties of refined grain in one day and one night, and it only needs a few people to operate it day and night." Feng Daiwen agreed.

"How can this sunlight be used, Master Hou, please tell me." Qingyun asked at this time, like a child begging for candy, staring at Feng Daiwen eagerly with a smile.

"How do I know? If I knew everything, I would become a god. Why do I need you!" Feng Daiwen said with an angry look at Qingyun.

"Hey, in the heart of the old Taoist, Lord Hou, you are a land god, who knows astronomy from the top and geography from the bottom." The old Taoist Qingyun smiled and flattered.

"Okay! Old Daoist, you have learned how to flatter. Find something to observe yourself, and we'll talk about the rest later." Feng Daiwen also joked.

"Wow! Lord Hou, look at this ant's leg can be placed so huge, haha, look, look at it and look at me with its eyes." Qingyun old man took a magnifying glass, squatted down to find an ant, and looked at it. Looking at it, he said excitedly and loudly.

Feng Daiwen ignored the startled Qingyun, filled a bowl with clear river water, and observed with a magnifying glass.

Gently stir the water in the bowl, only to see that the originally clear river water has many small things under the magnifying glass, which looks quite turbid. When the magnifying glass is removed, the bowl of clear water is still spinning in the bowl.

Feng Daiwen nodded in satisfaction, and put away the magnifying glass. Although he didn't see the microorganisms in the water, he was able to see so many things invisible to the naked eye, which was enough for Sun Simiao. Continue to study.

As for the huge telescope, it can only be seen at night to see the effect.
