Lin Jian put the matter of establishing a successor behind him, and he was not in a hurry to go to the front yard to participate in the celebration banquet, and he always had to ask everyone to have a time to buffer his emotions, and asked Xiaoman to help him raise the lamp and study the drawings.

Lin Jian originally thought that it would not be so early, he invited Jiang Yue to see the marquee, and officially unveiled the layer of window paper on the principle of steam drive It has only been 14 months, and Jiang Yue, the former master of the world's engineering machinery and equipment, has incomparable attainments in astronomy, calendar and arithmetic, and designed a steam-powered pumping machine and a steam-driven car, and sent the drawings to the Guogong Mansion yesterday, and sealed them in the study room to wait for Lin Jian to return to read.

The pumping machine is not a new thing, Sichuan and Shu mining well salt digging to the salt layer, injecting water to dissolve the salt for brine, and then using the pumping machine to pump the brine out of the ground and boil it into salt; The extraction technology of shallow crude oil in Jinzhou Island in the South Seas is also used to extract the technology, which mainly relies on manpower or livestock—the craftsmanship of the world is far from being as backward as imagined, but the limited market, limited industry, and limited demand limit the further development of craftsmanship.

Chongzhou shipyard has a dry dock, in order to improve the efficiency of shipbuilding and ship repair, a super large dry dock volume often reaches tens of thousands or even hundreds of thousands of stones, to drain the water inside, there is no pumping machinery, only rely on people to poke and scoop is unimaginable.

Jiangning, Xusi, Huxi and other places are rich in minerals, among which the coal mine is the most needed in the world, and it is also vigorously promoted and used by Lin Bin. However, the biggest problem with coal mining in plains and low hilly areas is that the coal seam is a little deeper, and the groundwater will continue to seep into the mine. Groundwater needs to be pumped out of the mine so that the miners can mine the coal and stone smoothly.

In the past, coal yards used manpower and animal power to drain water - but the efficiency of manpower and animal power pumping was extremely slow, and only occasionally where conditions permitted, the hydraulic power was used to drive the pumping machine to carry out continuous operation.

Mining areas with mineral deposits and abundant hydraulic resources are particularly scarce, and the hydraulic drive provided by streams is also seriously affected by the season, and only such a coal yard has been found in Zhuxi County, Yizhou.

In this way, Zhuxi coal has been transported to Jiangning by sea, and the cost is even lower than that of transporting coal from Lishui Coal Yard, which is only more than 100 miles away and connected by canals.

Lin Jian first asked Jiang Yueneng to design a steam-driven pumping machine for coal yard drainage.

First, the problem of underground water seepage is the main reason why the cost of coal mining in Xusi area cannot be significantly reduced again, and there is an urgent demand for efficient pumping machines; The second is that the coal yard can provide sufficient and cheap fuel for steam pumps.

Different from the principle of using the boiler to generate steam to directly impact the impeller to drive, the steam engine designed by Jiang Yue used the steam to expand and condense in the cylinder to repeatedly push the piston and coupling rod to drive.

In Jiang Yue's explanation, it is the driving principle shown by Lin Jian before, and the driving force generated during the actual test is not enough to continuously drive the coupling rod to operate; Jiang Yue invited nearly 100 craftsmen to work hard to design dozens of sets of schemes for testing in more than a year.

Jiang Yue also knew that Lin Jian would return to Jiangning today, so he specially rushed to send the latest design drawings to the study room yesterday and waited for Lin Jian to read.

Lin Jian was far from familiar with the equipment of later generations, but Jiang Yue's drawing paper was concise and clear, and anyone who knew a little about the principle of steam expansion and condensation could see the working principle of the drive.

Although the efficacy of the original steam engine was bound to be immediately satisfying, Lin Jian believed that as long as he persevered, he could open the door to the era of steam machinery......

Lin Jian saw the steam engine drawings that Jiang Yue had just temporarily submitted yesterday, and the unhappiness caused by the dispute quickly disappeared in a blink of an eye, and he secretly felt that the wisdom of the people at the time was really not to be taken lightly.

Xiao Man saw that Lin Lian's mind was completely attracted to the rice paper diagram drawn by the long case like a mechanical monster, and he was no longer bothered by the matter of the succession just now, and asked: "What is the important thing, in the eyes of the husband, it is more important than the matter of establishing a successor?" ”

"This is the golden key that really opens the door to another era," Lin Jian laughed, proudly flicked the drawings with his fingers, and said, "Others regard craftsmanship and miscellaneous learning as a crooked and evil way, and a small way; In my eyes, the miscellaneous science of craftsmanship is the real way, and the royal road and the domineering imperial power technique passed down by the Confucian families are the small way......"

"Since the imperial power of the king is a small way, why is the husband like this today?" Xiao Man asked puzzledly, the matter of establishing a prince must be regarded as a very important matter in the emperor's hegemony, Lin Lian's actions today really startled them, that is, Gu Junxun, Liu Yue'er, Sun Wenwan, Gu Yingsleeve and other women did not dare to come to the study to visit at this time.

"The roots of tradition are too deep, and although they cannot go against the general trend in the end, they will not give in easily; The contradictions between these and the repeated pullbacks, if they are not handled well, it will be bloody," Lin Jian said, "At this time, no one will laugh at me in front of me for raising pigs and growing vegetables in Jiangning in my early years, but if everyone really wants to speak freely and have no scruples, Jiang Ning is afraid that more than half of the people will scold me: 'Swineherd'!" Most people will never admit that Huaidong can have today's achievements, in fact, I started from raising pigs and vegetables. The conflict between old and new ideas is more intense than imagined; It is not so easy for people to be receptive to new things. ”

"If it's a good thing, why is it so hard for people to accept it?" Xiao Man asked puzzled.

"Nothing new is made overnight, it is from coarse to refined, from ugly to beautiful, from expensive to cheap, from few to many," Lin Tie pressed the pattern of the steam engine with his hand, and said, "Not to mention anything else, let's just say that the four-wheeled carriage is very convenient to ride now, but how many people know that the small roller sleeve on the axle has taken nearly two years of time for dozens of craftsmen to make this thing?" There are no manpower and material resources invested by the Ordnance Supervision, the Iron Smelting Supervision and the Machinery Manufacturing Division; It must be converted into gold and silver, no less than 100,000 yuan. At present, although it has been produced, it is far from complete, and it still needs to continue to invest a lot of manpower and material resources - where will such a huge and long-term sustainable manpower and material resources come from? ”

"Oh," Xiao Man said as if he had realized, "Could it be that the husband wants to so resolutely prohibit the people of Huaidong from sitting in the sedan chair, it turns out that he hopes that the sedan chair will be prosperous......

Lin Jian nodded and said, "Many people think: as long as there are good things, there will be people who use them; But it doesn't make sense to use it to govern the country, but to think about it the other way: only when someone uses it can produce good things - to sum up, demand is the driving force that pushes everything forward. The gentry and eunuchs all sat in sedan chairs, and the peddlers and pawns were all poor, and they could have bad cars; If I spend 10,000 dollars to build only a few Chinese cars for me to ride, what do you think those people in the court just now will scold me? ”

"Extravagant," said the little man, grinning, "but I don't think it's true. ”

Lin Jian pinched Xiaoman's face, hugged her in his arms, and said, "With my position, I feel that it is difficult to do some things, how can it be easy to change to others?" In the past, it was only forbidden for Huaidong people to sit on the sedan chair, Huaidong was just rising, and everyone could be simple, so there was not too much opposition, and after these years, it was used to it, but it was still difficult to completely abolish the sedan chair. The current situation is that the powerful eunuchs and nobles will not be willing to walk, and can only take a car without taking a sedan chair, and Jianghuai is seriously insufficient in animal power to provide a sufficient number of carriages. I plan to use the name of preparing for cavalry to promote the horse breeding industry in Jianghuai and other places, and then in the name of revitalizing the horse industry, I will first ban the lifting of sedan chairs in the central Zhubu Temple, and then fully promote it to the prefectures and counties after three or five years—only in this way will the car-making workshops be able to benefit from it, and there will be an incentive to continue to improve the skills of car-making craftsmen. What is said above is only superficial, and it is only a symptomatic thing; When it comes to the national level, first of all, it is necessary to maintain the benefits generated by the car factory so that a relatively wide group can share and occupy it, and this group also needs to be able to shout out and express opinions in the upper echelons of the center, so that the whole direction can last for a long time and will not deviate or go back to the old road due to accidental factors......"

"......," Lin Jian pointed back to the drawings of the steam engine and said, "It's good to turn around and talk about this thing, but it looks really simple now." According to Jiang Yue's description, to build a 'bicycle' that does not use people and animals, the body of the car will cause a behemoth with a length of twenty or thirty zhang and a width, which is really unusable. Even if you use it to drive the pump, you have to force the coal yard below to accept it," Speaking of which, Lin Jian called the guards outside the door in, "Go to the front yard and invite Master Jiang Yue Jiang in, and then invite Jing Xuan Gong in......"

*****************

After adding the gift of Jiuxi, Jiang Yue and others also rushed to the Chongguo Mansion to participate in the banquet and celebrate, but they didn't expect that there would be a dispute in the middle.

Although the front yard didn't know what was going on, Lin Tingli, Lin Xuwen, Lin Mengde, Song Fu, Cao Ziang, Qin Chengzu, Sun Jingxuan and other Huaidong dignitaries were summoned to the inner house, and everyone waiting in the front yard could know that something big had happened - between speculation, Lin Tingli, Lin Xuwen and others asked the ministers to return to the front yard, but they couldn't see Lin Lian's figure, and Lin Tingli and others looked depressed and exchanged ears, which deepened the suspicion of other people who didn't know the inside story.

Lin Jian threw out the initiative of the public government meeting, and the dispute over the establishment of the heir could be regarded as stopping, and Song Fu and Lin Tingli also notified Sun Jingxuan, Hu Wenmu and other people who had not seen the inner advice to reassure them.

However, in addition to thinking about the public government meeting and the establishment of the heir, Lin Tingli, Song Fu and others were also worried that Lin Tie would lose his temper tonight and not come to the front yard to participate in the celebration.

When I waited for a stick of incense, I saw the guards come out and summon Sun Jingxuan and Jiang Yue into the inner courtyard.

Sun Jingxuan's daughter Wen Wan gave birth to a son for Lin Lian, if Sun Jingxuan was summoned into the inner courtyard alone, everyone still suspected that it was to discuss the matter of establishing a successor, but Jiang Yue was summoned in again - Jiang Yue only resigned from the official position of Si Tianjian after last autumn, and led the Machinery Manufacturing Department under the jurisdiction of the Privy Council, and his status in Huaidong has not been highlighted.

Sun Jingxuan saw that Lin Lian summoned Jiang Yue to go in with him, and he could guess why, and he didn't want to make Lin Tingli suspicious, so he explained when he got up: "Xu is discussing the new mechanical drawing submitted by Jiang Yue......

Lin Tingli and the others suddenly realized that Lin Tie was a master of craftsmanship, this was what they understood, it was when military resources were the tightest, and it was forbidden for Zhi Du to cut off Jiang Yue's side - not to mention that the matter of establishing a successor was like that just now, Lin Tie probably didn't want to rush out to see them.
