About two moments later, an explosion came from the direction of Guan Chong Cliff!

Shao Ding quickly rushed to the hatch: "Master, there seems to be a violent explosion and fire above the Guanchong Cliff, covering a wide area, it is by no means the appearance of an explosion of hundreds of catties of gunpowder, maybe 10,000 catties or more. More on that is not yet known. For the time being, there was silence all around. ”

Tu Xicai hurriedly said, "Okay, go back to the mast and continue to look." ”

Saying that, she knocked on the cabin door, Hui Niang opened the door, and Tu Xicai hurriedly walked in: "Venerable Master, the situation has changed suddenly, what should we do?" ”

Lin Xi drank the rice wine slowly, blinked, his eyes were sour, and he hadn't eliminated it: "What do you predict will happen?" ”

Tu Xicai said: "The Venerable Master, I, am not a general, and it is very difficult to predict. ”

Lin Xi asked again: "How is the Queen Mother's treasure hunting team doing?" ”

Tu Xicai said: "The torch left about three or four miles, suddenly to the east, suddenly to the west, but gradually to the north. ”

Lin Xi asked:

"I haven't been to this terrain, you tell me, what is the highest place about?

Also, there are still no guides and fishermen? Goose or dog? ”

Tu Xicai hurriedly took another map to see:

"The Venerable Master, about the highest here, is also called Eagle's Beak Rock."

Lin Xi said: "Quickly send a team of fast hands, just to the eagle's beak rock, the queen mother's treasure hunt, the principle is to use magnets to accumulate, the local magnetic field affects the Kunlun Qingyu Beidou peony hairpin flower wave pattern goldfish cage in the magnetic needle pointing, then it needs to have a certain volume, here the hills and tidal flats are available, the tidal flats can not hide this kind of thing, it must be hills, among the hills, if the fishermen cut down firewood and burn the fire, they will soon be able to strip the ground, so it is unlikely, it can only be difficult to walk, and the landform is not easy to distinguish, so it is easy to hide. Large-scale military operations can only be sheltered in such places.

Although the specific place still needs to be found, it is very quick to find around the eagle's beak rock.

If you can't find it within half an hour, you can only withdraw first, keep the base camp, and don't be greedy for merit. ”

Send more people, be sure to find a few dogs and geese.

Around our Xuanyi, dig some traps and throw some nails.

It's a pity that there is no barbed wire, otherwise they will not have to come back.

Both the open and dark whistles should be left in a few more groups. Arrange for water spirits to patrol the bottom and surroundings of the boat on a regular basis.

For the rest, you can arrange it yourself, and make it into a drill code in the future. ”

Tu Xicai hurriedly said yes, and then went to arrange.

After thinking about it and thinking about it, Lin Xi called Tu Xicai and Wang Zhong (Qing Xuzi) in again: "Now the situation is unknown, we just released nine groups of nine links, Taifu is very valuable, and he is not very easy to commit suicide, if he is martyred, he may kill some important people......"

Tu Xicai interjected: "Venerable Master, is it possible that he was forced to be helpless? ”

Lin Xi pondered for a long time, looked at Wang Zhong and Tang Hanlin, Wang Zhong said: "It is possible to be forced to be helpless. ”

Tang Hanlin said: "We should burn Zhang Hongfan to death." ”

Everyone suddenly realized.

Wang Zhong sighed: "Yes, we burned Zhang Hongfan to death, the pseudo-Yuan has no leader, in this case, their strongest forces are roughly three, one is Turuk, the illegitimate son of the pseudo-Yuan Great Khan Kublai Khan, one is Zhang Qi, the son of Marshal Du Wanhu, and the other should be Li Heng, who has always been used as a reserve and a blocking force, and the other forces are too scattered." These three forces have many fleets of their own, and if one or two of them are killed by Taifu.

But this situation, for us, is also not optimistic, they have no leader, and they are bound to string around to avenge and plunder their leader.

Do you want to get ready to go to sea? ”

Tu Xicai said: "The supplies on our ship are almost exhausted, even if we go to sea, with oarsmen, less than ten miles, we have to lie on our stomach, that is not to be slaughtered by others." ”

Wang Zhong said: "Then prepare the sails." ”

Tang Hanlin said: "This, but it makes it, and now there are a lot of palace maids, and they sew some out overnight." ”

As he spoke, he called Zhen Niang over, and when Zhen Niang heard this, her head shook like a rattle: "If you go back to a few adults, we will only make clothes and sails, and someone will tell us how to do it. ”

Tu Xicai said: "What's so difficult about that, just find someone to tell you the size." ”

Zhen Niang was a little crying and laughing: "Commander Tu, do you want to use the remaining silk to sew the sails of the three or five zhang?" Truth be told, the hot air balloon already has some silk threads. The left and right are the things of the Venerable Master, but if you want to use them, you can't say whether the rest can be sewn out five zhang long. ”

Tang Hanlin said: "This is dangerous, on the eastern front of Yashan, there are actually many infantry and horse troops, although it is difficult for them to rush at night, but Tianming will definitely attack." It's less than three hours until dawn. Even if they bury the pot and cook and come back early after eating, it will only take four hours at most, and if there is no obstacle, in one hour, the Ma army may be able to drive more than sixty miles. ”

Tu Xicai said: "For today's plan, if you come up with the materials at the location of the Queen Mother's treasure, it is still the best choice." ”

Lin Xi said: "Our people have been fighting for almost a day and a night, and tomorrow morning, we will inevitably be sleepy and difficult to continue." Now it's time to do a good job. Also, our strength is too small, and we still need people. ”

Tu Xicai said: "Venerable Master, do you want to reduce the lights to prevent the pseudo-Yuan from discovering from afar, and they may be engaged in battle with the Song soldiers...... We may be able to have a little more time and be safe. ”

Tang Hanlin and Wang Zhong both looked at Lin Xi, this kind of big right and wrong, big life and big death choice, no one can easily express their position.

Lin Xi thought for a full two minutes.

Opening:

"Stretching out the head is a knife, and shrinking the head is also a knife.

You make another group of nine rings, only for this zenith fireworks, Song Bing will inevitably have confidence when he sees this, and someone will also withdraw from it, you arrange people to carefully identify, if you arrive, drink water, eat, and arrange for turns on duty, of course, they are all on the periphery.

Even if they save a few Song soldiers, it's good, they have sacrificed enough. ”

At that moment, several people saluted, although this kind of solution, they were somewhat expected, but Lin Xi was broad-minded and eclectic, and no one could figure out how to choose in the end. Now Lin Xi plans to put up a big banner and recruit Song soldiers, which is basically a good thing.

If there are more Song soldiers, such as a few thousand, then even if they fight to block, they can resist for a while.

If the fire yaksha is enough, the Song soldiers will fight in front of the attack, and the Xuanyi guard will cast the fire yaksha in the back, and it may be difficult to deal with the cavalry, but the infantry army should be difficult to shake.

If there are tens of thousands of people - well, you can only wait until the treasure of the Queen Mother is unearthed, otherwise one breakfast, you will run out of supplies, and at noon, you can only fight back or surrender.

As he spoke, the team that made the battery came in, and brought in a very ugly thing, Lin Xi looked at it, it was similar to the drawings.

Mi Sanmei and Song Qing and a copper master and a few small workers were all waiting for Lin Xi to speak.

Lin Xi opened the wooden box of the battery and saw that there was a piece of copper at the bottom, and there was a thin copper sheet attached to it, which was said to be a thin copper sheet, which was also half an inch wide, and was carefully connected to the round hole at the top.

On the copper skin is a piece of cloth soaked in salt water, then there is a square piece of lead, and the piece of lead is pitted, which can be seen to be the result of rushing work, and then there is another piece of cloth soaked in salt water, on which is padded with a square copper sheet, and so on.

Mi Sanmei said: "Venerable Master, there are 36 pairs in total. ”

Lin Xi looked at the top lead, and also left a thin belt half an inch wide, which was connected to another hole at the top.

Then Lin Xi quickly touched the two metal holes with his left and right index fingers, but he felt almost nothing.

Lin Xi said: "Take some copper wire, it doesn't need to be long, half a foot and a foot can be." ”

Song Qing ran out, and after a while, he came over with copper wires, copper wires, and copper sheets.

Lin Xi picked up the thinnest copper wire, pressed him to the copper hole with his left hand, and took the copper wire with his right hand to pluck the lead hole, and the small sparks of innocence lit up between them, and everyone was surprised.

Lin Xi had a smile on his face, no matter what, as long as this small spark appeared, there would definitely be voltage.

Lin Xi handed the thin copper wire to Mi Sanmei: "After it is done, you can do the simplest test, but it must be light or fast, this kind of spark is consuming the energy in the battery." ”

Mi Sanmei picked up the copper wire, and also followed Lin Xi's example, holding down the copper wire and copper hole with her left hand, and using the copper wire with her right hand to pluck the hole of the lead, and sure enough, there were thin sparks.

Lin Xi continued: "There is a small jar of salt water next to it, if the electricity is small, use salt water to re-wet the cloth inside, if it is wet, it is not a problem, dismantle the things, wash the cloth with clean water, re-soak it in the salt water, and then put it in, use concentrated salt water for the salt water, not too light." ”

And they all said yes.

......

Lin Xi looked at the light of the candle together, and suddenly remembered that there was already a battery, why not solve the problem of luminescence?

Electricity is used to emit light, the original use of filament, in a vacuum glass bulb, heating the filament precious metal to high temperature to emit bright light, this is the incandescent lamp, incandescent lamp greatly changed the life of human beings, so that the night can also move.

Later, fluorescent lamps were invented, and ultraviolet rays excited by mercury vapor were energized to excite phosphor powder again, resulting in fluorescent lamps.

If you don't add phosphor, and use quartz glass, then the ultraviolet rays will penetrate out and form an ultraviolet lamp, which is not only an artifact of disinfection, but also an artifact of yin people in this era, and the eyes will be painful and swollen after a long time, difficult to see, and even blind.

But these are too difficult to meet the current conditions.

Technological upgrades are also needed......

That's right, and later developed an electronic product called semiconductor PN junction, which is even more unreal.

Further back, by the way, further back, there is another thing, which can actually be regarded as an application of natural night pearls, that is, zinc sulfide.

Lin Xi even remembered that zinc sulfide had matured to the point where it could emit light with spraying methods, even very low voltages.

That's it!

Lin Xi had only done very few such experiments, and the main thing was to verify the technology at the beginning.

Now, the problem with crossing is that no one prepares these things, they have to prepare them themselves.

Lin Xi probably remembered that to use zinc sulfide powder, it is best to use nano powder, or ultrafine powder, in order to increase defects (holes), it also needs to be doped, such as copper, silver, aluminum, etc., and also needs electric field excitation, fortunately, a type of zinc sulfide only needs a few volts of voltage to emit light.

Now, do it.

Thinking of this, Lin Xi said to Mi Sanmei, Song Qing and the copper master:

"That's already enough, you guys do a few more.

In addition, I have to make a thing, I need to use a battery to test it for a while, and now this battery has only one voltage, and you will make a group of such batteries in a while, but from the second, fifth, tenth, twelfth, and twenty-fourth pairs inside, each of them is mixed with a copper piece of lead, guide the outside, and mark it. ”

The coppersmith wrote down the requirements with a pen and a small notebook, and went back.

Lin Xi pondered for a moment and said:

"We also need to make something that can emit light with batteries, but I don't know if we can make it.

We need to give it a try, and any of you need to take a closer look at what I'm doing and document it in detail.

You have to prepare your things first.

The first thing is to find something like a hollow glass jar. ”

Song Aoxing pointed to Hui Niang: "Hui Niang knows this kind of thing best." ”

Hui Niang immediately jumped out of a glass bottle from the water spirit gift that Lin Xi had picked just now, and there was an empty glass ball in the center, this bottle was imitating the appearance of the Guanyin water bottle, Lin Xi looked at it and put it down.

The second hollow glass ball is actually a lamp, which was originally designed to be able to drink water, and Lin Xi stayed:

"The second piece is to grind the best Japanese lead into a fine powder, one or two coins (note: about 3 to 6 grams) immediately."

Song Qing said: "I'll do this." ”

Lin Xi said:

"In the third piece, you take a silver plate, and after a while, let the copper master make a small copper seat, put the silver plate on it, and then pile the fine charcoal underneath, set it on fire, record a little from the low of the fine charcoal, and blow the wind with a leather basket.

You've got everything ready, and you're here to make it, and I'm looking at it. ”

Song Qing said, "Okay, I'll go down and prepare." What else is commanded? ”

Lin Xi thought for a while:

"Let them grind some more fine powder of silver, and scrape it down, and prepare a penny or two;

In the preparation of a copper plate with a thickness of one millimeter and a foot of length and width, it is necessary to polish both sides and be clean;

Prepare some excellent cooked tung oil.

Then take two pounds of brass or gold. ”

Song Aoxing said, "Could it be that the Venerable Master is talking about the power of medicine? ”

Lin Xi said: "That's right, what kind of rice do you need to use to drum up those precious gold leaf and rhinoceros horns?" ”

Song Aoxing laughed: "The Venerable Master is really blessed, and there is no such thing as a prison general, only some rough guys, but it just so happened that Xuanyi Lu was here before, and they once took one from the pharmacy of the Imperial Medical Bureau, which is very valuable, and I will take this one." ”

Lin Xi said: "Very good, you guys prepare things, come here." ”

......

At this time, the jade master came over with people and two lenses in the car:

"Venerable Master, according to your teachings, we have coarsely polished two lenses, please take a look at them first, for fear of making inappropriate words and delaying time."

Lin Xi thought that this jade master knew this kind of characteristics of research and development very well, nodded, and took two lenses.

Sure enough, I saw that this lens was about two inches in diameter, and it was a convex lens, and the arc seemed to be smaller than that of a small concave lens.

The other concave lens, about an inch in diameter, is flat on one side and concave on the other, Lin Xi feels that it should be concave and not small.

First picked up the large convex lens, Lin Xi held it with his hand, and moved it straight down from the upper end of the position of the center level, and then saw that a horizontal log in the bulkhead was slightly bent in the movement up and down.

Lin Xi showed it to the jade master's car: "Look, take the lens, move it up and down, the horizontal line, if it is bent, it is not good." If the line of the tree moves and bends, it is not good. ”

The master jade craftsman looked in the car, moving his hands up and down in front of him, left and right, and after a while, he seemed to understand: "What the Venerable Master instructed me is that I still feel that my production is seamless and flawless. ”

Lin Xi said: "But it's too harsh, you don't have experience, slowly master it first, and then explore it deeply." ”

The master jade craftsman bowed in the car and saluted: "Thank you, Master." ”

Lin Xi looked at the concave lens again, and sure enough, there was some bending.

Then, Lin Xi held the convex lens with his left hand and the concave lens with his right hand, and then moved back and forth, about a foot and a half before and after, Lin Xi saw the magnification effect, and it was a positive image.

[Note:

If a telescope looks at a person or object in the distance, if it is upside down and left and right in the eyepiece, it is a negative image, and if it is normal, it is a positive image.

Usually both elements of Kepler telescopes are convex lenses, a type of refractive telescope, the objective lens group is convex lens form, and the eyepiece group is also convex lens form.

This kind of telescope imaging is upside down, left and right, but the field of view can be designed to be larger.

It was first invented by German scientist Johannes Kepler in 1611.

In order to achieve an upright image, some refracting telescopes with this design, especially most binoculars, have added an image rotation mirror system to the optical path.

In addition, almost all refracting astronomical telescopes have Keplerian optical systems.

Galilean telescope: The objective lens is a converging lens and the eyepiece is a telescope with a divergent lens.

The real image formed by the refraction of light through the objective lens is on the focal point behind the eyepiece (near the back of the human eye), which is a virtual image of the eyepiece, so it is refracted into an amplified upright virtual image.

The magnification of the Galilean telescope is equal to the ratio of the focal length of the objective lens to the focal length of the eyepiece.

The advantage is that the lens barrel is short and can be orthodox, but it has a relatively small field of view. A device in which two Galilean telescopes with low magnification are placed side by side and the sharpness of the telescopes can be adjusted at the same time with a bolt button in the middle, which is called a "theater viewing scope", and the visual experience of this telescope is better than that of a monocular.

Truly from a manufacturing point of view, two convex lenses are much easier than one concave lens.

Lin Xi had to produce usable results as quickly as possible because of the urgent production, so he naturally chose the Galilean telescope. 】

Lin Xi asked the jade master to come to his eyes in the car and came to see.

After the jade master's eyes moved in the car, he suddenly fell backwards, and then looked up at Lin Xi in surprise:

"Venerable Master, are you—witchcraft?"

Tang Han Lin was angry: "In the car, the Venerable Master is here, Hugh is talking nonsense, if it is, it is also magic." ”

The jade master hurriedly snorted a few times in the car, and pretended to slap his mouth: "The Venerable Master forgives sins, the Venerable Master forgives sins, Xiao Ke is too surprised and talks nonsense." ”

Lin Xi said: "Okay, that's it, you can see it, if you move back and forth, you can see far away." This is the telescope, not a divine technique, but a divine revelation, the rules of the Shinto heaven and earth, which are discovered and properly used.

Go back and make a concave lens, and also make a convex lens with the same radian, which can see farther, but it is upside down, left and right upside down. You can see it in the distance. ”

The jade master hurriedly said yes in the car.
