PS: Thank you for the reward from the book friend Water Margin!

Just after the Dragon Boat Festival, the weather is getting hotter and hotter, but it is not only the weather that is full of enthusiasm.

On a construction site behind Dulonggang in Yanggu County, Yunzhou, hundreds of villagers are leveling the land, planting fruit trees, mulberry trees, and building fences on the hillside in full swing. It's a lot of fun.

This was originally the land of Zhujiazhuang in Dulonggang, and after Zhujiazhuang was destroyed by Liangshan, in addition to the good land that was divided, the remaining land, as well as this mountainous land, also belonged to the Liangshan army.

Because this place is really close to Liangshanbo and even closer to Hujiazhuang, Lin Chong simply designated this area as the garrison of the Liangshan Army and stationed troops here.

Not far from the station, this large mountainous area, there is also a large stream that has also been designated by Lin Chong as the exclusive economic zone and workshop location of the Liangshan Army.

Lin Chong has already explored, and the terrain here is really good, as long as he chooses a place to build a dam of about two zhang, he can turn the upper reaches of this big stream into a reservoir.

At the same time, two embankments were built on the earthen hills on both sides of the stream, which were about one zhang and eight feet high from the stream, and mulberry trees were planted on the embankments to raise silkworms.

Lin Chong plans to turn this place into an ecological farm.

That is, to build a dam, build a reservoir, raise fish and lotus root in the reservoir, plant mulberry forests on both sides of the bank base, and raise silkworms with mulberry leaves; At that time, silkworm dung and silkworm pupae can go to the reservoir to raise fish, and mulberries can be eaten and brewed; The silt at the bottom of the reservoir can be fished out as fertilizer for mulberry forests.

On the higher slopes of the mulberry forest, it is also leveled to be used as vegetable plots, and various vegetables such as peppers, tomatoes, and watermelons are grown; Further up, various fruit trees such as fragrant pears, apples, and peaches are planted;

Chickens can also be fenced off under the trees in the orchard, and they can be fed a little feed every day, and then let them find food on their own; Ducks can be raised on the water surface of the reservoir, chicken manure can be used as fertilizer for orchards, and duck manure can be used as fertilizer for reservoirs.

In short, it is to try to form a cycle, and all aspects are fully utilized, so that the farmers who have taken refuge in the Liangshan Army can get the maximum profit.

However, Lin Chong's biggest purpose is not in agriculture, but in industry.

Lin Chong barrage dam is built in order to use water power to propel machinery for industrial production.

In fact, Lin Chong wanted to design a hydraulic hammer for Ye Meng and others as early as the beginning of the mountain, but because of the Liangshan smelting workshop, the ironwork processing workshop was really top secret, and it was not easy to put it outside, so Lin Chong had to retreat and design an animal-powered hammer on the mountain.

The general hydraulic machinery, such as water mills, water mills, water wheels, etc., has long been common in the Great Song Dynasty, and some have even been thousands of years old, and at the latest from the Western Han Dynasty, there have been water mills.

Therefore, Lin Chong said at the beginning that he would build a water mill and a water mill here, but everyone didn't pay much attention to it.

It's just that not long after the water mill was run, after defeating Hu Yanzhuo and returning to the mountain, Lin Chong, Ye Meng, Shui Yun, Tang Long and others tinkered for half a day every day, which took almost a month. Today, a set of equipment has finally been produced and commissioned, and everyone who knows about it is simply overjoyed to hear it.

Now is the time to put this equipment into practice and test its effectiveness.

At this time, the outside of the workshop area next to the embankment was already heavily guarded, and the inside of the workshop area was crowded with people, and everyone was full of expectations.

Shi Jin rode a charcoal red horse, with seven or eight personal soldiers, galloped all the way to Dulonggang, and saw the hot scene on both sides of the embankment from a distance, and couldn't help but sigh.

He received a letter sent to him by Lu Zhishen early on, and more than 20 days ago, he took the Shaohuashan team all the way to Liangshan to join the gang in disguise as a thief arrester.

Because Lu Zhishen is Lin Chong's "senior brother", Lu Zhishen has the best relationship with Shi Jin in addition to Lin Chong, so Shi Jin's gang was quickly reused after joining the Liangshan Army.

Because Zhu Wu was proficient in formations and was extremely good at strategy, after a few days of inspection, he was quickly appointed as a staff division, and his status ranked in the top ten of all the people in the Liangshan Army.

And Shi Jin and others were also appointed as the chief general of the Liangshan Army's infantry army, and the official was in charge of 2,500 infantry, and let Chen Da, the jumping tiger, and Yang Chun, the white flower snake, be his lieutenants.

However, because the Liangshan Army was expanding, Shi Jin, a newcomer, naturally could not let him command two thousand five hundred Liangshan veterans.

Therefore, more than eighty percent of his battalion infantry were recruits, including the "bandits" they brought from Shaohua Mountain, as well as the Song army that surrendered under Guan Sheng and Liang Fangping, as well as a small number of peasants who joined the army.

Only about one-and-a-half percent of the Liangshan veterans served as the backbone to help Shi Jin, Chen Da, and Yang Chun with recruit training, and their camp was near the northern city outside Liangshanpo.

But what kind of person is Shi Jin, he is young and in his early twenties, and he has long been a little impatient with such boring training day after day.

No, as soon as he found an opportunity, Shi Jin left the training to Chen Da and Yang Chun, and rode a horse to find Lin Chong with people.

Soon Shi Jin and his party came to the outside of the workshop area, and after taking out the military badge to report, several people were allowed to go by the guards, and the group left one to watch the horse, and the others followed Shi Jin to go inside.

Before they could reach the factory, they heard a burst of exclamation and cheers from inside, Shi Jin's eyes were hot, and he hurriedly took out his military card and signaled to the guards, and strode in.

I saw a group of people surrounding a machine that they had never seen before, all with light in their eyes, their faces were red, and they were indescribably excited and excited.

"My mother! Is this hydraulic silk reeling machine developed by my brother really powerful? Otherwise, why would everyone be so excited? ”

Can you not get excited?

Even if many people have long been accustomed to all kinds of magic brought by Lin Chong, Lin Chong can always bring forth new things every time, and always bring new surprises to everyone every time.

And everyone Rao has been mentally prepared, but when they see it with their own eyes, they can't help but marvel again and again, because it is too much for them to imagine.

Lin Chong has long wanted to engage in hydraulic silk reeling, and even he plans to go further in the machinery of the hydraulic silk reeling machine in the near future to get out the water spinning, which will greatly improve productivity.

But this is a matter of urgency, take this hydraulic silk reeling machine as an example, this machinery to say simple and simple, complex and complex.

To say that it is simple is nothing more than to use the water turbine as the power to drive the silk reeling machine.

To put it simply, silk reeling is to kill the silkworm cocoon in boiling water, and then find one end of the silk, and pull out the silkworm cocoon to extract the slender and long silk.

In the beginning, silk was wound on a silk basket, and then a spinning wheel was gradually introduced, so the silk was wound on a spinning wheel.

Compared with the Tang Dynasty, the silk reeling machine in the Song Dynasty was already very advanced at this time, because the silk reeling machine in the Tang Dynasty was hand-cranked, the left hand cranked the spinning wheel, the right hand reeled the silk, and it had to stop from time to time, and the efficiency was very low.

The Song Dynasty invented the pedal spinning wheel, which liberated both hands at once, and the efficiency was increased several times, but compared with the efficiency of silk reeling in later generations, it was still far away.

So Lin Chong improved the silk reeling machine on the basis of the silk reeling machine of the Song Dynasty, combined with the advantages of the later Jenny spinning machine, and let more than a dozen or dozens of silk reeling machines be linked at once, and at the same time the water turbine replaced the pedal to provide power.

Such a design is really nothing for Lin Chong, an engineering dog who graduated from mechanical manufacturing and automation at university, so it is simple.

To say that it is complicated, although Lin Chong designed straw paper, this era did not have as many technical school graduates in later generations, let alone processing machinery such as lathes in later generations.

Even though Ye Meng, Shui Yun and others are all skilled craftsmen, and their wisdom is not worse than that of later generations, after all, the silk reeling machine is a precision machine, and the silkworms at this time in the Song Dynasty are much thinner than the silk more than a thousand years later.

This requires that both the water turbine and the silk reeling machine must be made very finely, and there can be no slightest error, so as to ensure the smooth operation of the silk reeling machine, which is a great test of the level of these craftsmen of the Liangshan Engineering Bureau.

After some debugging just now, the water turbine drove the silk reeling machine to start idling, and saw that all the hundreds of reeling cars automatically rotated together, and the rotation was very stable, and the speed was also very uniform, everyone couldn't help but be overjoyed and exclaimed loudly.

Lin Chong also relaxed slightly at this time, and then when he saw Shi Jin striding in, he frowned slightly, nodded at him, and signaled him to wait for something.

Then he turned his head and said to a weaver who was guarding the boiler not far away, "Raise the fire!" ”
