Chapter 259 Rifling and Thermite Reaction

After the concubine's quarrel was over, King Su also made a big fuss in the clan's mansion, insisting that the governor of Shandong made a mistake, and the corpse in the coffin was not his son at all.

The emperor let him go back to see his son for the last time, but King Su insisted that the soaked corpse was not Li Zhao at all, just like the concubine Shizi, and wanted to light the corpse with a fire pocket just like the concubine Shizi.

So the seventy-year-old Zong Ling had no choice but to make another trip to send the third prince, His Royal Highness King Su, to the imperial mausoleum to calm down.

It doesn't matter whether Li Zhao died or not. The emperor made it clear that he wanted to cut off King Su's arm, to kill his most useful son, and to shake those who followed King Su in private.

On the surface, everyone was convinced that Li Zhao was dead, but both the emperor and the Shenjun Palace were sending people to find Li Zhao's whereabouts.

However, His Royal Highness Su and the concubine's disturbance in the mourning hall undoubtedly disturbed the emperor's calculations. Those courtiers who planned to stay away from Su Wang couldn't help asking a question in their hearts. Is Li Zhao dead?

Where would he be if he really hadn't died?

Baoen Temple.

Song Qingyue, who had been shaved and bald, took a big mouthful of the Roujiamo that Zeng Maozhi had bought secretly, chewing with great satisfaction.

Being suppressed by the old nun Jingxuan and eating vegetarian food for three days is really an old crime.

Zeng Maozhi stared at Shi Zifei's bald forehead without saying a word, and asked with a relaxed look, "You, are you okay?"

"Can't you see if I'm okay?" Song Qingyue looked at Zeng Maozhi and Qiu Shi with a funny face, put her legs on the small stool, and said, "Okay, for the sake of being shaved and bald, can you tell me?" Where did my dead ghost go? Did he go to the south? "

The word "dead ghost" made Zeng Maozhi's eyebrows twitch, but he thought it was very appropriate. He wanted to laugh but didn't dare to laugh, his facial muscles twitched, and he didn't know how to answer. It's still beautiful!
Seeing that he was still silent, Song Qingyue snorted, "Don't tell me! If you don't tell me the truth, I'll pack up and run away, change my name and surname, and marry someone else! Anyway, he's buried in the ground!"

Qiu Shi was honest, and immediately apologized with a smile: "Concubine Shizi, don't make such a joke, His Royal Highness misses you the most. You guessed right, His Highness went to the south. No, a few days ago our family There are also spies in the palace, let’s not talk about it, it’s for the safety of you and your son!”

Song Qingyue snorted again, took a big bite of Roujiamo bitterly, chewed it a few times, and asked, "What does the palace mean? Why did you send someone to watch me? Could it be that the old man in the palace wants to see it too?" See if our son is really dead?"

Zeng Maozhi lowered his head and touched his nose, and said, "His Highness Changsun did send several groups of people to search for His Highness's body. As for the palace, it's hard to say."

"Ha! The old man must have acquiesced in this matter. He wanted to support the deposed crown prince, so he tried every means to weaken Su Wang's mansion and Jing State mansion to pave the way for the crown prince, and he didn't want to make the crown prince too strong all at once. , Threatening himself, so he still wants to keep us alive for a few more years. Hmph, it's really cruel. Our Royal Highness can be regarded as a filial son of the old man." Song Qingyue shook her head.

After the concubine's analysis in a few words, the doubts in my heart suddenly became certain, and Zeng Maozhi and Qiu Shi were shocked. If this is the case, His Majesty is too ruthless today!
Qiu Shi couldn't believe it, he shook his head and said, "No way! Your Highness is His Majesty's favorite grandson!"

Song Qingyue rubbed her stomach, feeling full, but seeing the half meaty roujiamo, she decided to take another bite. Hearing what Qiu Shi said, Song Qingyue just smiled and swallowed the food in her mouth , handed the remaining half of the Roujiamo to Mo Ju, rinsed his mouth, wiped his mouth clean, and said: "King Shan is abolished, our mansion has been tossed to death, there is still a mansion of Prince Yu, wait and see Well, once something happens in Zhejiang, His Majesty will definitely attack the Duke of Jing."

Touching her full stomach, she went for a small turn around the back mountain of Baoen Temple.

Mo Ju carefully accompanied her, and said in a low voice: "Concubine Shi Zi, don't be too sad, let's grow our hair, and it will grow back."

Song Qingyue touched her bald, round head. Ever since she wore it, she had never felt her scalp so refreshed. In this quiet temple, there was nothing to call her except the old nun Jingxuan who made her trouble. In a bad mood.

Halfway through the walk, there were sporadic raindrops in the sky, so Song Qingyue had to go back to her meditation room to take a nap. When she woke up, she found Zeng Maozhi and Moju Molan, and said, "Moju Molan, it's closed tonight." At the courtyard gate, don't let anyone in, just say I'm in a bad mood and don't want to see anyone. Master Zeng!"

"The subordinate is here!" I don't know where Zeng Maozhi is hiding, but when Song Qingyue called, he appeared immediately.

"Let's go to the cave tonight." Song Qingyue laughed.

After dark, Song Qingyue went to the cave secretly.

The masters have already explored some ways in the heat treatment of steel before.

That is, don't anneal too fast, keep a certain temperature for a period of time, and then let it cool down slowly, so that the barrel produced in this way is more durable and can withstand more and more violent gunpowder, which can greatly reduce the explosion of the firecracker. Chances of firing.

It's just that the length of the heat preservation time and the temperature control masters are still groping.

Sometimes technological updates are like this. With the right direction, breakthroughs will be very fast.

Baoen Temple is not close to the cave, and Zeng Maozhi needs to carry her halfway up the mountain every time, and then drive her there on a fast horse. Counting the round trip time, she can't spend more than an hour and a half in the cave.

So she needs to make short stories about everything, and she will write down the things she thinks of in detail on paper in advance for the reference of the masters.

For example, this time, she came here to help the masters improve the design of the musket.

The master looked at Song Qingyue's new drawing, stroked his thinning beard and asked, "You mean, engraving such spiral rifling in the barrel can increase the shooting range?"

Song Qingyue nodded: "Before I thought you couldn't make it, so I didn't mention it, but I've been idle in the temple these days, so I'll let you know when I think of it."

"This thread can be made with a broaching machine, but it takes a little effort. Is there a trick to the angle of the thread?"

Song Qingyue laughed: "I have to trouble you to adjust it slowly, try it slowly. You can also try to adjust the length of the gun barrel."

"No problem, leave it to us!" The master blacksmith also laughed.

Song Qingyue suddenly had the feeling of being a mentor. She provided an idea, and someone helped to do the dirty work.

"There is also the design of the bullet. This cone is too straight. You can try to make the sides slightly curved. This streamlined shape can fly farther in the air than a straight cone." Song Qingyue drew a schematic diagram on paper, "And I think we can consider covering the lead bullet with copper, otherwise the temperature will be high, and the lead will melt and get stuck in the rifling, and the rifling will be meaningless."

"Why is the tip of this bullet changed to a curved shape?" The masters were puzzled, because the cost of creating a curved tip is much higher than that of a simple pointed tip.

"Just like a boat, the bow is also curved, isn't it?" Song Qingyue laughed, "Bullets flying in the air will suffer the same resistance as a boat sliding in water, and the streamlined shape will suffer more than such a pointed and straight shape." Less resistance."

"So that's it! Why didn't we think of it before!" A young master exclaimed with bright eyes.

But the master craftsmen are holding their chins and considering using this "streamlined design" on large shells.

The cost of using it on bullets is too high, and the range may not increase too much, because the volume of the bullet itself is very small.

But shells are different. They are large in size and have a large cross-sectional area, so the "air resistance" received is greater. Such a small change in shape may greatly increase the flight distance of the shell and lengthen the firing range.

Song Qingyue glanced at the huge and heavy mechanical clock in the cave, and said again: "I can't stay here for too long. I'm here today, and I want to talk to the masters about welding. Didn't you say that aluminum has been successfully extracted?" ? Give me a small aluminum strip, help me make it thinner, and I will do an experiment for you to see."

The hardness of aluminum is very small, and it becomes a flat piece after a few blows.

In fact, Song Qingyue wanted aluminum foil, but it doesn't matter, you can try it first.

She found a rusty iron, scraped off some rust powder, put it together with the aluminum bar, and ignited it with red phosphorus, but it didn't work.

Song Qingyue slapped her head. She didn't have any magnesium bars to ignite or potassium chlorate to generate oxygen.

How to increase the flame temperature?
Increased oxygen levels?

So Song Qingyue asked the masters to bring the hand-cranked generator, insert the cathode and anode in the light salt water, collect oxygen from the anode with an upside-down funnel, and then leak it out through a catheter.

At the same time, another master made the aluminum flakes thinner and ground them into powder.After that, the aluminum powder, which is not too small in size, is mixed with rust powder and red phosphorus powder.

Finally, the mixture is placed in a crucible, which is ignited while passing oxygen.

Sure enough, after a few seconds, those powders burst out with astonishing light, illuminating the entire cave!

The masters who are doing other research have cast their inquiring eyes, and some of them even put down their work and came to find out what happened.

After the light faded, the cave was filled with choking smoke, Song Qingyue couldn't bear it, and ran towards the exit, coughing while running.

But those curious master blacksmiths squatted down to observe what was left in the crucible, as if they were not affected at all.

A black lump.

"what is this?"

A young and daring person grabbed it with his hands, and naturally he was scalded and screamed. An experienced master immediately brought over a small water tank. After a period of chaos, a blacksmith picked it up with iron tongs. Get a closer look at that lump of stuff.

"Isn't this iron?"

"iron?"

"Did it turn rust into iron?"

"Seems to be!"

"Hey! This is amazing!"

After running to a place with fresh air, Song Qingyue finished coughing, covered her mouth and nose with a handkerchief, and turned back.

"Concubine Shizi, is this lump iron?" asked the old master.

Song Qingyue said: "Yes, the remaining slag is alumina powder."

These masters have all listened to Song Qingyue's basic chemistry class, know what oxygen is, and what oxide means.

"Aluminum reduces iron oxide. Simply put, the oxygen atoms on iron are taken away by aluminum."

"Ah! So it is!"

Song Qingyue hesitated and said, "I'm wondering if this reaction can be used for welding."

"Welding! That's right! This way we don't need to put it in the furnace!" A master exclaimed excitedly.

Song Qingyue said again: "It's the propeller that I mentioned before. It can be placed at the stern. Masters, let's think of a way. Maybe we can use this reaction to make it."

Previously, because propellers could only be cast as a whole, only small propellers could be made, which could not meet the propulsion requirements of large ships at all.

But with welding technology, plus screws and nuts, it should be possible to create propellers suitable for medium-sized warships.

Of course, it is not necessary for Zheng He to use such a large treasure ship on his voyages, and the treasure ship itself is not a warship.

What Song Qingyue wanted to build was a warship with fast speed and strong maneuverability, and its size and displacement could not be equated with combat power.

After saying this, the time was almost up, and Song Qingyue had to return immediately.

After leaving the cave this time, Song Qingyue spent another leisurely time in the temple.

She sleeps until she wakes up naturally every day, and after getting up, she goes out for a walk to exercise her body. When relatives and friends come, she will receive the guests. If no one comes, she will go back to the house to write physics and chemistry textbooks.

At this stage, it is still completely fragmented. She just randomly lists some knowledge points that she can think of.She planned to wait for enough knowledge points to be listed before slowly organizing them into a system.

Knowing it yourself and teaching others to understand it are two completely different things.

In the communication with the cave masters, she discovered that several times she used a knowledge point that others did not understand to explain another knowledge point that they did not understand, and then she was like a nesting doll, more and more, and more The more people talk, the more confused they become.

She also wants to try her best to recall what she learned in junior high school, but many times, the content learned in junior high school, high school and even some universities are mixed together in her mind, and it is really not easy to sort out the order .

At this time, Li Zhao had already arrived in Fujian by sea.

After resting in Fujian for a few days, I was planning to board a boat in Kinmen to Xiaoliuqiu, which is opposite.

Governor Ou of Fujian and Governor Shen of Guangdong both came to see Li Zhao on board.

This time Li Zhao brought them on board, in addition to the [-] sailors and infantry secretly trained in the Lingnan border, there were also many blacksmiths and old craftsmen who made fireworks.

Su Wang's Mansion encloses a large piece of land on the west side of Xiaoliuqiu.

More than ten years ago, when King Su and Li Zhao first came to the island, they had a fight with the natives of Xiaoliuqiu.

Those who are willing to surrender will be incorporated into the navy team, and those who are unwilling to surrender have already been driven to the mountains in the middle of the island.

Now that Li Zhao wants to bring more than 5 people to the island, he will inevitably need a bigger territory. After he lands on the island, he will have to compete with the locals on the island for territory.

Li Zhao's idea is to include as much as possible if he can, and if he can't, he has no choice but to fight.

It happened to train soldiers with Fanzi.

Xiaoliuqiu is a good place. It is warm and humid after the season, and the land is fertile. Rice can be grown twice a year. It would be a pity not to occupy such a good place.
