Hearing Yang Peng's words, Cha Yunke pondered for a while and did not speak. Yang Peng also wants to run to the sea. As a businessman, Chayunk didn't want a competitor to compete with him to buy. With one more competitor, the purchase price of raw silk in Bianjing will be higher, the price in Waguo will be lower, and Chayunke's profit will be lower.

But Chayunk is not only a businessman, but also an official businessman. The most important thing for officials and businessmen is their connections. Yang Peng is extremely powerful, and helping Yang Peng go to sea can earn Yang Peng's favor, and there will be endless benefits in the future. For example, the relationship between Cha Dengbei and Yang Peng doesn't seem to be very good, and he does Yang Peng a favor, and he may be able to use it at a critical time in the future. Cha Yunke weighed it again and again, and finally said: "Lord of the city, these shipbuilders are doing illegal and private ship building, and ordinary people can't inquire about them. If an ordinary person wanted to ask me about a shipbuilder, I would never say it. But since the lord of the castle has spoken, I must help with this favor. ”

Yang Peng smiled: "Gongzi Zha is an interesting person!" Chayunke said, "I will bring the shipbuilder to meet the lord of the city tomorrow, and the lord will wait for me in the palace." Yang Peng arched his hand and said: "Then Yang Peng is waiting for Gongzi at home." "Early the next morning, Cha Yunke entered the Yang Mansion with three craftsmen with thick turbans." This leader is Wang Boss, the shipbuilder head of Wangjiawan. ”

Yang Peng looked at the leading craftsman and saw that he was low in stature, with dark skin and calluses on his hands, and he looked like a fisherman. Yang Peng asked, "What kind of ship will you build?" That Boss Wang seemed to have seen a lot of big officials, and when he saw Yang Peng, the city lord, he didn't flinch, but said calmly: "Lord Taibao, the small one will build a local pointed boat in Dagu." This ship is sharper than the bow and flatter than the ship, which is especially suitable for running on the northern seas. The general pointed head ship is made of 2,000 materials. The captain can have ten zhang, three decks on the water, and the cabin is divided into more than a dozen watertight cabins, which can run the Japanese country. If you are brave, you can run in the South Seas, as long as you don't encounter a hurricane, you will be fine. ”

In the Song Dynasty, one foot was similar to one foot in later generations, three feet and one meter, and ten zhang was thirty meters. Yang Peng pondered for a while, and felt that the ship that Wang Datou said had a displacement of more than 200 tons. Cha Yunke explained: "My lord, the two thousand materials that Boss Wang said are civilian materials, and they are different from official materials!" Yang Peng asked, "How much silver does it cost to build such a ship?" ”

Boss Wang said: "It depends on what kind of ship the adults want to build!" These woods for shipbuilding are good and bad, and they also need to be dried in the shade, and the price is different for different years of drying. If a man wants to build a good ship, and to repair a ship that can be used for six or seven years, he will need four thousand taels of silver, six hundred and two cedar wood, two hundred and ninety-eight miscellaneous wood, forty wood trees, four elm rudder rods, four chestnut wood, and seventy-six oars. If it is worse, only two or three years of inferior ships, the wood used is very different, and the joint does not need to be soaked in snakeskin and inner ointment, and it can be nailed with iron nails, and the cost of two thousand taels is enough! ”

A good ship of more than 200 tons costs 4,000 taels of silver, which is not cheap. Yang Peng said: "What if I want to build a bigger ship? For example, a big ship with 4,000 materials. The craftsman looked at Yang Peng and said, "Then I can also build it, but I need more labor, if I want to build a big ship of 4,000 materials that can be used for six or seven years, it will cost about 10,000 taels of silver." ”

"If you want to build two big ships of 4,000 materials, if you want to be faster, how many months?" "The little one will find all the craftsmen who are familiar with each other nearby, and it will be made in five months." Yang Peng nodded and said, "Do you know the ribs of the ship?" The craftsman was stunned, thought for a moment and said, "The little one doesn't know." ”

Yang Peng said: "I want to install a strong crossbow on the ship, and I must lay wooden ribs on both sides of the keel to support it. If you don't understand, I'm not afraid, I can teach you. "In the Song Dynasty, seagoing ships generally adopted a watertight cabin structure, which was very technologically advanced and allowed the ship to sail as a whole even if it was partially damaged. The hatches of the watertight compartment also provide lateral support for the vessel. However, this support is relatively limited and cannot withstand the recoil of the strong crossbow. The recoil of the crossbow is supportable, but if you want to install a crossbow on board, you have to lay the ribs of the ship.

Yang Peng had previously learned about the structure of the ribs of a wooden sailing ship, and this was just the right time to come in handy. With Yang Peng's knowledge and the experience of these old shipwrights, I believe that he will be able to make the ribs of the ship. The bow didn't expect that the city lord still knew the technology of shipbuilding, and he was skeptical there.

Cha Yunke knew that Li Zhi was a skilled craftsman, and knew that Yang Peng didn't know how many new things, he believed that the ribs of the ship that Yang Peng said must be useful new things, and said to Boss Wang: "Boss Wang, your luck is here, you can learn new skills to help the city lord build ships, and you can make a lot of money this time!" Boss Wang scratched his head and said, "I really don't know what a ship rib is, and I need the city lord to advise." ”

Yang Peng nodded and said, "Two big ships of 4,000 materials cost 20,000 taels of silver?" Can it be cheaper? Boss Wang said calmly: "My lord, all we earn is handicraft money, and the materials are sufficient." Buy as much money as you can and build as much material as you want. If the adults give us less silver, we will have to buy less materials to make smaller ships, or buy less materials, and the ships will not last for so many years. You can give as much silver as you want, but the boat you end up making is different. ”

Cha Yunke also said: "Your Excellency, rest assured, these shipwrights are all craftsmen, just to earn a piece of craft money, and will not be greedy for Lord Mo's silver." He also built my ship, and he has repaired it every year over the years, and the money spent on it is worth it. Yang Peng thought for a while, nodded and said: "Okay, I believe in you, I will give you 10,000 taels to buy timber first, but I will send someone to purchase with you and register and make accounts." When the wood arrives, I'll teach you how to make ribs. In addition, I will build two paddle wheels, and I will teach you together when the time comes. ”

Boss Wang said, "Okay! Don't worry, your capital is so sufficient, I will definitely buy the best materials to ensure that your ship can last for seven or eight years! Yang Peng smiled and nodded.

The cost of shipbuilding of 20,000 taels is not a small number, and Yang Peng wanted to send someone to supervise the cost of the shipwrights, so he sent Qiu Ju, a subordinate of Zhan Jinguo, to supervise the purchase of Wang Laoda. Han Jinxin is trustworthy, Yang Peng believes that no one is staring at Han Jinxin, and Han Jinxin, the former official of the imperial court, will not spend money indiscriminately. Qiu Ju, the procurement in the army, first went to be the shipbuilding superintendent.

Yang Peng returned to Tianjing New Town and found an independent courtyard in the crossbow workshop as a research place for steam engines. The principle of the steam engine is very simple, it is nothing more than the use of the expansion pressure when the water is heated into steam to push the movement, and then the use of the vacuum suction movement generated when the steam is cooled into water.

In later history, the practical steam engine appeared in the early eighteenth century, and it was also out of reach of the Song Dynasty at this time. One of the more famous ones is the Newcastlemen steam engine. The principle of this steam engine is very simple, that is, after pushing the piston with the power of steam, cold water is injected into the cylinder to cool the steam, so that the vacuum generated can suck the piston back. Repeat these two movements, and the change can be transmitted outward.

Historically, several thousand units of this simple steam engine were produced and were widely used in coal mines in England to pump water from the mines. The use of this steam engine helped England become the largest coal producer in Europe in the early eighteenth century. Yang Peng had never actually made a steam engine, so he decided to start with the simplest Newcastlemen steam engine, which was easy first and then difficult. Make the Newcastlemen steam engine first, and then upgrade it.

However, to make a steam engine, Yang Peng first had to do a simple lathe. Without a lathe, you can't finish steel objects. Yang Peng has made a boring machine before, and the structure of the lathe is similar, except that one is a rotating boring cutter, and the other is rotating the object to be processed, but the same place is to rotate one thing to grind another, and the structure is similar.

Yang Peng instructed the blacksmith and spent five days making a simple lathe and using the crucible steel he had refined to make a turning tool. The lathe that was finally made can only be said to be a primitive lathe, but it was enough for Li Zhi to use. After the lathe is produced, it can be used to turn pistons. Yang Peng wants to make a cylinder with a diameter of 30 centimeters, first cast it with pig iron, and then finish it with a boring machine. Inside the boring machine, a piston with an same diameter of 30 centimeters is placed. Yang Peng asked the blacksmith to cast the shape from pig iron, and then the lathe finished it.

After repeated comparison, processing, comparison, and reprocessing, Yang Peng finally got two cylinders and pistons that fit perfectly. Yang Peng put the cylinder with the chassis open on top of the boiling water, and now the piston is completely leaking. Even if the water vapor is pressed in at a higher pressure, the air leakage will be very slow. Yang Peng made a push rod on the piston, which was pushed by the piston moving up and down.

Then there is the cooling device, Yang Peng fixed a cold water bucket next to the piston, the cold water bucket is connected to the bottom of the cylinder, and there is a valve at the connection. Make a mechanism control valve at the outermost end of the actuator, if the actuator is pushed to the top by water vapor, the mechanism is opened, and cold water is sprayed into the cylinder to cool the vapor. As soon as the water vapor cools, the piston drives the push rod downward, and when it reaches the bottom, it touches the mechanism to close the cold water gate, and so on.

Then it's time to make the boiler. This boiler must be large enough to produce enough vapor to propulsion. After the boiler is ready, it is connected to the cylinder, and the whole Newcastle door steam engine is ready. Yang Peng spent five days making the parts, screwing the parts together, and began to test whether the work was successful.

As soon as the boiler was hot, Yang Peng was leaking air everywhere in the entire steam engine. There was not much air leakage between the finished piston and the cylinder, but the connections of those pipes were threaded together, and the gap was large, and water vapor was sprayed everywhere.

However, even if there was a leak everywhere, the steam engine was successful, because the degree of water vapor burned out of the boiler was higher than the degree of leakage in the pipes. The water vapor pushes the piston to do work, constantly moving up and down. Because of the air leakage at each pipe, the air pressure in the cylinder is just controlled, and the degree of up and down movement of the push rod is relatively stable, seven or two times.

This Newcastle Gate steam engine can be regarded as made. However, the Newcastle Gate steam engine was very inefficient, and it took a lot of wood to produce a limited amount of thrust. This is because cooling the water vapor in the cylinder also cools the cylinder block, and then after a while, the hot steam comes in and heats the cylinder block, wasting a lot of heat back and forth. Such an inefficient steam engine obviously could not meet Li Zhi's needs, and Yang Peng wanted to gradually transform this Newcastle steam engine into a Watt steam engine. Watt's biggest improvement to the Newcammen steam engine was the condenser. With a condenser, the cylinder block is not repeatedly heated and cooled. The condenser is actually a large iron canister connected to a cylinder with cold water in it. The switch of the condenser is controlled by a mechanism, and when the piston is pushed to the top, the switch is turned on and the vapor enters the condenser to cool into water. When the piston falls to the bottom, the switch is turned off, and the vapor has nowhere to escape and collect in the cylinder, pushing the piston up again.

However, when making a condenser, Yang Peng now requires a higher air pressure for this condenser than the method of water spray cooling, and such a high air pressure cannot be gathered in the pipes that leak everywhere, so he must find a way to block the leakage. But there is no high-temperature resistant rubber these days, and Yang Peng thought about it, but he didn't think of what he could use to plug the leaking pipe. Yang Peng had no choice but to test the softer materials available on the market one by one. But I tried all kinds of textiles, and the results were not good. The silk, which looked very slippery and soft, was burned by the high temperature steam, and it became charred and clumpy. The material that is more resistant to high temperature is linen, but the pore size of linen cloth is large, and it cannot block the leakage of vapor.

After testing for several days, Yang Peng still couldn't find a material that could plug the air leak, and Yang Peng was a little stumped. The principle of this watt-type steam engine is simple, but the details are still very complicated, even if one detail is not done well, it cannot drive the whole steam engine to run.

Speaking of copper, or lead is relatively soft, and can withstand hundreds of degrees of high temperatures, is it necessary to use copper and lead as pipe joints? It's a lot of trouble to do. A young blacksmith who was transferred by Yang Peng to make a steam engine watched Yang Peng make a Newcastle Gate steam engine like a trick these days, and he admired Yang Peng very much. At this time, he saw that Yang Peng was in trouble, and interjected: "City Lord, if you soak the linen cloth in oil for a day, the aperture in the linen cloth will be blocked by the grease, which may be useful." ”

Yang Peng was stunned, but he didn't expect that there was such a way. He patted the young blacksmith on the head and did as he did. Wrap the oil-soaked linen cloth around the threaded connector, tighten the connector, and restart the steam engine.

At this moment, Yang Peng is now no longer leaking on the pipeline. Yang Peng said to the young blacksmith: "The suggestion is good, reward you with ten taels of silver!" The young blacksmith was so overjoyed that he laughed so hard that he almost grinned at the back of his head.

Since the last time Huyan Chijin returned home, Yang Dezheng has been pestering Huyan Chijin all day long to talk about how to beat Xiao Tianyou, either he is practicing plum blossom darts, or he is practicing handcuffs, Yang Bamei chatted with a few aunts, since the last incident, the commander of the copper hammer class in front of the palace, the copper hammer Cheng Pu has retired from the family, and now Yang Bamei is twenty-five years old and has not yet married, and it is an old girl in the Great Song Dynasty. The people in the family are also in a hurry, and Yang Qi doesn't care.

Yang Yanzhao's heart, he can't say it to the Eighth Prince, and he won't tell it to the Eighth Prince. Faced with the eighth prince's question, Yang Yanzhao replied: "The eighth prince, the prince and the general, for the kid, it is only a matter of time. The kid feels that today's Yang family, there is no need to risk the lives of their relatives for the sake of wealth. ”

Yang Yanzhao said sincerely: "In the kid's heart, the lives of relatives are far more important than wealth. The Eighth Prince stared at Yang Yanzhao with a complicated expression, he can be regarded as a well-informed person. Like Yang Yanzhao, who values the lives of his relatives more than wealth, he has not seen much. After being silent for a while, the eighth prince shook his head and sighed, "You kid, you take your feelings too seriously." ”

Yang Yanzhao shrugged his shoulders and said with a smile: "Maybe......" The eighth prince smiled happily, "Your personality will not please Your Majesty......" Yang Yanzhao said indifferently: "It doesn't matter......" The eighth prince laughed, "It doesn't matter if Your Majesty doesn't like it, the old man likes it." The old man has been playing tricks and tricks all his life, but the old man doesn't like those who play tricks in front of the old man. ”

"This world is destined to be ruled by literati and emperors in the future." Throwing down this sentence, the eighth prince laughed and left. Yang Yanzhao smiled lightly, the eighth prince can say this, then it proves one thing. In the Taimiao, the content of the stele erected by Zhao Kuangyin is known to the Eighth Prince. The eighth prince is clicking on him. vaguely told him that the literati had a transcendent status in the Great Song Dynasty.

Yang Yanzhao drank all the tea, paid the tea money, and went home in a sedan chair. returned to the east courtyard of the Yang Mansion, took a closer look, and found that after Chai Xichun went out, Yang Yanzhao relaxed a lot. After a brief meal, he began to practice in the courtyard with a tiger-headed black gold gun.

The twelve-style routine of the Liuhe Army's war gun, Yang Yanzhao can already practice it completely. Now it just needs to be consolidated. After a set of marksmanship, Yang Yanzhao was sweating profusely. When I was about to go back to my room to wash, I saw the fallen leaves hurriedly entering the east courtyard.

"Something?" Yang Yanzhao asked. Fallen Leaf made a cold face and nodded, "All the things under the ground in the house have been dug up." Yang Yanzhao was stunned for a moment, and said cautiously: "Take me to see." Yang Yanzhao followed the fallen leaves and rushed to the foot of a place in the west wing.

There are several simple wooden houses built there. A group of craftsmen, consciously or unconsciously, guarded the perimeter of the wooden house. These craftsmen are all impersonated by the hands of the Volcano Battalion. The craftsmen saw Yang Yanzhao and Falling Leaves, and secretly made a way for the two to pass. Entering the wooden house, seeing the rows of lead pipes placed in the wooden house, Yang Yanzhao's face was gloomy.

"There should be more than thirty of them, right?" Fallen Leaf said coldly: "The lead pipes in the four rooms add up, there are more than one hundred and forty pipes. Yang Yanzhao banged on the lead pipe, making a dull sound. The bottom of the east courtyard has not been dug yet. In other words, the number of lead pipes under Yangfu may exceed two hundred. Yang Yanzhao clenched his fists, and a cold glint flashed in his eyes.

"It's vicious." Yang Yanzhao turned his head and asked Luoye, "What do you think?" Falling Leaves glanced at Yang Yanzhao and said lightly: "According to the investigation of his subordinates, these lead pipes were buried after the people of the Yang family moved in. When Yang Yanzhao heard this, he gritted his teeth and said, "What do you mean...... There were a large number of traitors in the Yang Mansion at that time, and it is possible that these people are still lurking. Fallen leaves nodded.

"Check!" Yang Yanzhao spit out a word in hatred. Fallen leaves hesitated for a moment and asked, "What should I do after I find out?" Yang Yanzhao stretched out his hand and patted the lead pipe, and sneered: "Don't they like to bury the lead pipe?" Once the identity of the spy was verified, he was put into these lead pipes and buried alive. ”

Hearing Yang Yanzhao's order, Luoye did not have the slightest expression on his face, and nodded in response to Yang Yanzhao's order. Originally, when he was in the early dynasty, he got a bargain from Gao Huaide, and Yang Yanzhao was still in a good mood. However, after seeing these lead pipes and learning about the hidden spies in the Yang Mansion, his good mood disappeared in an instant.

With a gloomy face, he returned to the East Courtyard. After pouring a few mouthfuls of water, Yang Yanzhao lay on the simple sofa and felt stuffy. Yang Yanzhao didn't have long to be bored. Chai Xichun went upstairs with the corner of his skirt. Seeing Yang Yanzhao lying on the simple sofa, she snorted coldly.

"Humph!" After a long time, seeing that Yang Yanzhao did not respond, he snorted coldly again. Yang Yanzhao lay on the sofa and muttered, "Don't hum, I'm annoying." Chai Xichun was slightly stunned and ordered the cicada to go down first. Pacing in front of Yang Yanzhao, seeing Yang Yanzhao leave with a gloomy face, the expression on her face also changed. "What's wrong?" Yang Yanzhao took Chai Xichun into his arms.

"The pipes under the house have been dug out, and there are more than one hundred and forty pipes. This is not counting the ...... in the underground of the East Courtyard" Chai Xichun's eyes widened, "How can there be so many?" Yang Yanzhao smiled, his laughter was very cold, "After the underground of the East Courtyard is dug up, there may be more." Chai Xichun bit his lips lightly, "Lang Jun, why don't we move, and when the lead pipes in the east courtyard are disposed of, we will move back." ”

Yang Yanzhao was stunned, "Move there?" Chai Xichun said softly: "When the concubine got married, my father gave me a house, not far from Xiangguo Temple. Yang Yanzhao thought for a moment, nodded in agreement, and said, "Listen to your ...... However, if you move out for no reason, if the people in the family ask......" Chai Xichun patted his chest and said: "It's handed over to the concubine, and when my father and mother ask about it, the concubine said that it was uncomfortable to live here and wanted to rebuild the East Courtyard." The concubine believes that her father and mother will not worry about the concubine because of these trivial things. ”

Yang Yanzhao grinned. Chai Xichun said that he would do it, and he had already gone to let the cicadas pack up their things. When he arrived in the evening, Chai Xichun had already instructed Cicada to pack the required items into the car. The servants sent to clean up the house not far from Xiangguoji Temple have also returned. "Lang Jun, let's go now."

Yang Yanzhao looked at the empty bedroom and was dumbfounded. "Chai Xichun, don't be in such a hurry, right?" Chai Xichun snorted, "How can you not be in a hurry, the major matter related to the inheritance of the heirs cannot wait for a moment." ”

After all, what happens next, let's see how it will be broken down next time.
