Zhao Ta told everyone in the audience about the origin of the Zizaimen and the level of martial arts, but some of the secrets were naturally not mentioned, but everyone was shocked when they heard it, they didn't expect that there would be such an ancient sect.

Zhao Ta said: "This has been in the door for a long time, and Songshan Temple can't be compared with it, but it has been trapped in the territory of Western Xia for more than a hundred years, so the Central Plains gradually don't know." ”

Bai Zhan said: "Lord Wang, since it is a sect handed down by Zhuangzi's ancestors, it should return to my Middle Earth, how can it be suspended in the territory of Western Xia for a long time?" ”

Bai overbearing: "The third child, what nonsense!" ”

Bai Zhan said: "Big brother, what did I say wrong?" ”

Bai Ba hated iron and said: "Under the whole world, it is not the king's land, the shore of the land, it is not the king's minister, since the prince wants to change his name to Rouwolf Mountain and break through Helan, then Western Xia will also be Middle Earth!" ”

Bai Zhan was stunned, and immediately bowed his head and said: "Lord Wang, it's because my subordinates are too stupid, I just thought that the ancient inheritance of Zizaimun was actually in the Western Xia country, and I was angry in my heart to say this." ”

Zhao Ta said: "It is a good thing to have righteous indignation, so I want to point my sword at Western Xia and destroy this shameless country." ”

Everyone said yes at this moment, and at this time, Liu Suiyun came in and saluted: "Lord Wang, the Xihe soldiers have withdrawn and camped in the distance." ”

Zhao Ta groaned slightly: "Just take precautions, don't worry about the rest for the time being, it is estimated that in less than two days, these military horses will leave." ”

Liu Suiyun responded: "The arrangements in the city have been completed, and the West Gate has also quietly sent scouts to inquire about the news." ”

Zhao Ta bowed his head, asked a few more words about the military situation, and suddenly said: "Longyou produces water jade, send someone to the state treasury to check whether it exists, if there is, pick some clear ones and send them to the mansion." ”

Liu Suiyun wondered when he heard this, but said, "My subordinates will call someone to do it immediately." ”

Water jade is crystal, which was discovered and used as decoration in ancient times, and has been mentioned in many books since the Spring and Autumn Period.

Crystals are not valuable at this moment, because most of them look cloudy, and the processing technology at this time is backward, and the perfect cutting and polishing effect cannot be achieved, so the appearance is not as attractive as in later generations.

And at this moment, the crystal stock is quite large, not only in the east coast, but also in the northwest, whether it is dignitaries or dignitaries, ordinary people, are not very interested in this kind of stone that is not rare and seems to have a lot of impurities, except for some special forms and colors, there is probably no value.

Then Zhao Ta ordered everyone again, got up and left the lobby to go back to the mansion.

Not long after, Shi Jin brought someone to carry a wooden box over, and said: "Lord Wang, this thing is not valuable, and there is not much in the state treasury. ”

Zhao Ta was sitting on a chair in the courtyard listening to Xiao Zhao Xi's recitation of poems, and nodded when he heard the words: "Take them out and I'll take a look." ”

Shi Jin took the order, opened the wooden box and took out more than a dozen crystals, Xiao Zhao Xi was curious on the side, and he didn't memorize the poem, so he walked over and said, "Daddy, what are these things?" It's ugly, there's a lot of dirt in it. ”

Zhao Ta leaned over to look, and couldn't help frowning slightly, only to see that the crystal stored in the state treasury and carefully selected was not clear at all, and it looked very turbid.

He thought about it, in fact, this is already good in the world, and the ordinary ones are not as good as the ones in front of him, and the crystal thing probably depends on cutting and polishing, otherwise the large ore body will not be too crystal clear.

"It's called water jade." Zhao Ta said to Xiao Zhao Xi.

"Daddy, this is also jade?" Xiao Zhao Xi's eyes widened immediately: "It's not like jade at all, it's like the melting earth and ice in the courtyard in spring, it's not good at all." ”

Zhao Ta shook his head: "What do you know, I will make you a good thing later." ”

"Lord, are these still applicable?" Shi Jin listened to Xiao Zhao Xi's words and couldn't help but say.

Zhao Ta touched his chin, in fact, he didn't know whether it was applicable or not, because he had not cut and polished the crystal.

He wanted to make a telescope, but to be honest, he could barely burn out glass, but he couldn't make a telescope out of ordinary glass.

So he thought of crystal, and the first telescope in the true sense of the word was made of crystal, and for a long time, telescopes were made of crystal.

He had this kind of thought, all because he remembered a person named Sun Yunqiu in later generations, who lived in the late Ming and early Qing dynasties and was born in a declining official family.

This person is smart and studious, when he was young, he went to Hangzhou to learn glass-making technology, and in the late Ming Dynasty, Hangzhou was the center of glass-making, at this time, not only there were glasses and other things, but even the self-striking bell was available, and Sun Yunqiu had invented the method of calibrating the self-striking clock.

At this time, glasses were expensive and not available to ordinary people, so Sun Yunqiu pondered how to reduce the cost of making mirrors.

Based on the mirror-making skills he learned in Hangzhou, combined with his own mastery of metaphysics and physics, after countless practical accumulations and explorations, he finally mastered the technique of "grinding the piece to light", creatively grinding the lens with crystal material, and also created the drag car for grinding the lens.

After his careful research and improvement, the grinding mirror has greatly improved the light skills, and the cost has been greatly reduced, on the basis of grinding convex lenses and concave lenses, he has used crystal stones to grind into eyepieces, kaleidoscopes, mandarin duck mirrors, magnifying glasses, illusion mirrors, luminous mirrors, clairvoyant mirrors and other types of light mirrors.

This clairtelescope is a telescope, and according to Sun Yunqiu's production method, it is easier and cheaper to make than according to the method of Western fan.

To this end, Sun Yunqiu also wrote a book on mirror making, called "Mirror History", according to the book, the use of crystal as raw materials, the top car grinding lenses, according to the different needs of people to make, even ordinary people can afford to use.

Zhao Ta read the book "History of Mirrors", which recorded more than 70 kinds of manufacturing methods for mirrors, most of which were polished with crystal, so he came up with the idea of using crystal to make telescopes.

At this time, he heard Shi Jin speak, thought for a while, and said, "Take people to the market to take a look at it, there are more crystal clear water jades to buy back, especially purple water jade." ”

Amethyst is the best material in crystal to make mirrors, and if there is an amethyst, he is more sure.

And once the telescopes are manufactured, one or two will definitely not be enough, at least the generals above the Wei Ji level must have a pair, and the leader of the scout team must also have a pair, so as to have a better insight into the enemy's situation, increase the victory rate on the battlefield, and avoid unnecessary casualties to the greatest extent.

"Daddy, what are you going to do for Xi'er?" Xiao Zhao Xi asked with a blink of eyes at this time.

Zhao Ta stood up, walked around the crystal block in the box a few times, and then said, "You'll know in a while." ”

He wanted to make a drag car, Sun Yunqiu invented the item of polishing the lenses, and in that era, almost all of them were directly grinding the mirrors by hand, not to mention the laborious and laborious, and it may not be accurate, and the material will be wasted if you are not careful.

But since the advent of the car, this situation has been completely reversed, because the car can fix the spar that you want to polish, and even some thin and thick bumps can be mastered, and after polishing, you just need to refine and correct it.

However, this thing needs to be cranked by hand, similar to using a small grinding disc to grind sesame oil, but it is not effortless, after all, the spar is not too large to be polished, and you can turn the handle on the car.

There are two major problems in manufacturing telescopes, one is cutting, and the other is polishing, these two problems can be easily solved in Zhao Ta's place, he has the Mo Evil Sword in his hand, he can cut the crystal at will, and he knows the manufacturing method of the car, which can be processed and polished, as long as the crystal is suitable, it should not be difficult to build a telescope.

"Daddy, are you going to make a plaything for the child?" Xiao Zhao Xi immediately became happy.

"Sort of, let's make a drag cart first." Zhao said with a smile.

"Lead...... Touriston? Xiao Zhao Xi had never heard of this name, "Daddy, is this car fun?" ”

Zhao said: "It's fun, it's fun." ”

Xiao Zhao Xi immediately pulled the corner of Zhao Tayi's clothes: "Daddy, I want to hold the cart!" ”

"Okay, Daddy will take you to do it now." Zhao Ta touched Xiao Zhao Xi's head and led him to the martial arts arena, followed by the guards around.

The martial arts arena of this Xining Mansion is far less big than that of the Tokyo Palace, so it can barely run away from the horse, and on one side of the martial arts arena is a small forest, most of the leaves are green, but a few of them have not survived the winter, and they are still withered.

Zhao Ta slipped out of the Mo Evil Sword in his sleeve, and cut a lot of dead wood in a moment, and then thought for a few breaths, and said to Zhou: "Go find some copper foil, if you don't have it, take the copper money and melt it, and then find iron nails of different sizes and thicknesses to send it over." ”

Zhou immediately took someone to find it, and Zhao Ta began to make a drag cart according to his memory.

Originally, this was a carpenter's work, but if the carpenter built a cart according to the drawings, it would take five or seven days, because it had to be sawed, planed, and adze, and finally it had to be assembled with some copper and stone things.

But Zhao Ta didn't need it, Mo Xie's sword sharpened iron like clay, and he cut it directly what he wanted, so it didn't take long for him to get the wooden frame materials necessary for the cart, and then sent iron nails from around, and he "ding-ding-clang" and beat it.

The wooden frame of the normal cart is embedded with a wedge, but he has never learned carpentry, and he is afraid that the inlay will not be good, so he directly uses nails to nail.

The nails of this era do not have the nail heads with flat heads on the top, they are thick at the top and thin at the bottom, the nail body is irregular, and there are several edges, once all of them are nailed, the surface of the wood is still very flat.

Zhao Ta nailed the frame of the cart, looked at Zhou, and said: "Lord, the copper foil is being smelted, I asked people to wait over there, and I will send it over as soon as it is ready." ”

Zhao Ta nodded: "Let's go find some sand, cold water stone, lead essence and rough bamboo, and by the way, bring the box of water jade in front of me." ”

Cold water stone is gypsum, lead essence is mercury, and everywhere immediately went to find it.

It didn't take too long, Zhou prepared these things and sent them over, and then Zhao Ta began to assemble the cart, and when it was almost there, the copper foil came again, and he wrapped the soft part of the cart and said with a smile: "It's done!" ”

Xiao Zhao Xi wondered beside him: "Daddy, is this a car?" ”

Zhao Ta said: "It's the car." ”

Xiao Zhao Xi circled around a few times: "Why doesn't the car have a wheel?" Still so small? ”

The bottom of the cart is flat, and it is half a foot square, similar to the shape of a wooden box, hollowed out in the middle, and there is a small door to put things inside, which is not like a car at all.

Zhao Ta stretched out his hand and pointed to it, there were four small wooden discs directly above the cart, and he said, "Aren't these four wheels?" ”

Xiao Zhao Xi wondered: "Daddy, this ...... Is it? ”

Zhao Ta said: "You shake it and try it." ”

Xiao Zhao Xi stretched out his hand and grabbed the rocker to push and shake, and the four small discs actually rotated together, and he immediately said in surprise: "Daddy, you can really move, all four wheels have moved." ”

Zhao Tan smiled: "Wait for Daddy to make you a fun thing." ”

After speaking, he picked up the Mo Evil Sword again, picked up a slightly better crystal stone, "swished" a few times, cut a few small slices according to the records in the "Mirror History", trimmed the corners and corners, and put them under the four discs on the car.

Then he mixed the sand, cold water stone and lead essence in a certain proportion, and poured it into the groove between the discs, and said to Xiao Zhao Xi: "Come on, shake." ”

Xiao Zhao Xi said suspiciously: "Daddy, what is this doing?" ”

Zhao Ta smiled and said, "Just do what Daddy says!" ”

"Good!" As soon as Xiao Zhao Xi heard that it was fun, he immediately blushed and reached out to shake the handle of the cartridge.

Watching him "snort" hard, Zhao Ta poured the water into the groove little by little, and then said, "Shake slowly, don't worry." ”

"Okay......" Xiao Zhao Xi was very excited.

Zhao Ta glanced at him, took the bamboo tube sent from Zhou, walked to the side and sat on the leisurely chair, and slowly sharpened it.

In fact, he is not making a telescope, but making a kaleidoscope, first make a kaleidoscope to try his hand, see if it can be done, and then make a telescope if it is done.

The bamboo tube is the tube of the kaleidoscope, he took the sword to repair it exquisitely, and carved patterns on it, at this time Xiao Zhao Xi said on the side: "Daddy, I'm so tired, I can't shake it." ”

Zhao Ta went over and took out the crystal piece to take a look, frowned, the polishing was far from enough, he added some abrasives and water to the groove, and said, "Keep shaking." ”

"Yes...... Daddy. ”

Zhao Ta returned to the chair and continued to carve the bamboo tube, he was carving the monkey to learn the scriptures, and had just finished carving one of the pig demons.

"Daddy...... Child, child still can't shake a little......"

Zhao Ta got up and looked at it again, and refilled some materials and water: "Shake!" ”

"Good ......"

"Daddy, I, I'm out of strength......"

Zhao Ta is carving at a critical juncture at the moment: "Shake ...... again"

"Oh......"

"Xi'er, what are you doing?" At this moment, Zhu Xiuniang came over with Qingxing, and said with a frown as she walked.

"Mother...... Wow! When Xiao Zhao Xi saw Zhu Xiuniang, he immediately sat on the ground, wiped his tears and said: "Daddy, daddy told me to shake the wheel, I, I can't shake it, and my dad still asked me to shake ......"

Zhu Xiuniang's face turned a little pale when she heard this, and she walked closer and said, "Lord Wang, Xi'er is so young, where can Lord Wang let him do things, this ...... What is this doing? ”

She looked at the cartridge and didn't recognize what it was.

Zhao Ta finished carving the last stroke, blew at the bamboo tube, blew off all the silk chips, stood up and said to Qingxing: "Go cut some colored paper and bring it over, all kinds of colors are required, the size of watermelon seeds." ”

Qingxing turned around and trotted away, Zhao Ta went to the front of the cart and took out the crystal piece and looked at it, frowned slightly, and shook it.

Zhu Xiuniang was puzzled: "Lord Wang, what is this?" ”

Zhao Ta glanced at her: "Gewu!" ”

Zhu Xiuniang bit her lip when she heard this, Xiao Zhao Xi got up from the ground and said with a grin: "Mother, Daddy said that he wanted to make fun for the child, but as a result, he let the child shake the wheel." ”

Zhao Ta said leisurely: "It'll be fine right away." ”

Zhu Xiuniang took Xiao Zhao Xi's hand, looked at Zhao Ta and said, "This is what you are doing...... Karakuri? ”

Zhao Ta said: "It's Gewu!" ”

Zhu Xiuniang was silent, Zhao Ta polished for a while, took out the crystal piece from under the wooden plate of the car, looked at the sunlight carefully for a few breaths, and then put it in and continued to shake it.

After a while, Qing Xing came back with a wooden box of colored paper, Zhao Ta took out the crystal again, this time his brows stretched slightly, although it was still a little unsatisfactory, but it was just a kaleidoscope and not a telescope, but it was barely acceptable.

He began to wash the crystal pieces and assemble them in a bamboo tube, and put the colored paper the size of a watermelon seed inside, then sealed the edges with copper foil, made the tube firm and shook it a few times, looking at the sun.

Xiao Zhao Xi stopped crying at this time, and stared at the bamboo tube tightly: "Daddy, daddy, what are you looking at?" ”

"Here you go." Zhao Ta took back the bamboo tube and handed it to Xiao Zhao Xi: "Just look like Daddy just now." ”

Xiao Zhao Xi hurriedly wiped the tears on his face, and looked at Zhao Ta's appearance just now.

"Ah, it's so pretty!" He suddenly shouted, and then jumped up involuntarily: "Mother, mother, you also take a look, you also take a look." ”

Saying that, Xiao Zhao Xi sent the bamboo tube in his hand to Zhu Xiuniang.

Zhu Xiuniang glanced at Zhao Ta, silently took the bamboo tube, and then looked inside.

It didn't matter what I saw, I just felt that it was colorful and full of flowers, as if it was another world, and I was suddenly frightened and took a step back.

Zhao Ta laughed and said, "This thing is called a kaleidoscope." ”

"Daddy, this name is also good, the child likes it very much." Xiao Zhao Xi said happily.

Zhu Xiuniang pursed her lips and sent the bamboo tube back to Xiao Zhao Xi, arguing: "It's not still a clever thing." ”

Zhao Ta ignored her, and ordered Zhou to move the cart and crystal materials to the study, and his family also left the martial arts arena.

He pondered in his heart as he walked, since the kaleidoscope could be made, there must be no problem in building a telescope, but at the moment the quality of these crystals was a little poor, if Shi Jin could buy better crystals, then he would start making them immediately......
