Hu Buqi said: "Meng Yuan is powerful, the North Korean soldiers dare not oppose it, according to the spies, the eastern front is in the south position, there are also North Korean bow infantry Cui Zhen Gao Division, Yin Shooting Division, Yin Xihong Division, Chaoshan Division, and Han soldier Liu Guojie Division. We may have stabbed a hornet's nest. ”

Jiang Chen said: "In this way, it's a bit troublesome, let's take the light army and follow it, and we originally went to Eagle's Beak Rock to establish a base." Now, Song Yuanzheng, getting you safely to Eagle's Beak Rock is my top priority. Centurion Ding Cong? ”

Ding Cong ran over: "Director Jiang, what do you have to say?" ”

Jiang Chen said: "You send a herald to return to the trestle, and you must inform Marshal Tu and the Venerable Master of the situation." In addition, now that I have handed over the battlefield to you, even if the sergeants of the advance team are exhausted, I will send Minister Song and the masters of the Engineering Academy to Eagle's Beak Rock to protect them until the arrival of the large army. ”

Jiang Chen said to Song Aoxing: "Song Yuanzheng, the fighter plane is changing rapidly, we have leaked the bottom here, and now we will not kill the remnants of Mengyuan, and we will not burn the Great Willow Village, and our hole cards can already be touched away." So, I can only do the worst now and send you to Eagle's Beak. I'll be in the broken line. Don't stop all the way, without supplies, we are dead. ”

Song Aoxing held Jiang Chen's hand: "Good brother, it is not yet known who will kill the deer, as soon as we arrive at the Eagle's Beak Rock, we will first release the Kong Ming lantern to inform the Venerable Master." You don't need to delay to the death, once we get to the eagle's beak, we can take out our crossbows and defend first. ”

Jiang Chen said: "Okay, for the sake of victory, for the sake of justice, you... Let's go......"

As he spoke, Jiang Chen picked up the leather whip and whipped it towards Song Aoxing's horse's buttocks, the horse was in pain, and Changsi screamed and ran forward.

Jiang Chen said to Ding Cong: "Ding Baihu, I am now obeying your orders, you can arrange it!" ”

Ding Cong ordered to assemble, and then there were four or twenty fighters in the advance team, plus more than ten people in Jiang Chen's guards, a total of thirty people, Ding Cong said: "Brothers, just now we met the remnants of Meng Yuan, and now the war is changing, our task is to escort the master craftsmen of the Song Minister's Engineering Academy to the Eagle's Beak Rock Base to excavate weapons and materials, only by excavating these materials, we will have a chance to live." However, Meng Yuan's number of troops here has exceeded expectations, and we must protect the people of the Engineering Academy to set up camps, so that they can continue to provide us with weapons, and the Xuanyi Army we recruited can protect us.

Now, Master Jiang Chen Jiang has handed over the command to me and has taken on the task of blocking the attack.

Master Jiang can sacrifice his life and forget about death, let alone me.

Now I order, Jiang Chen's headquarters will cover the advance team of the engineering institute, block the attack, and the rest of the people will follow me to Ertan Village to establish a blocking line.

After that, they alternated cover to ensure that the Mongol soldiers were a mile away from the engineering academy.

Didn't you hear it all! ”

The crowd agreed, and the team quickly split into two parts and galloped away, leaving behind them only smoke billowing behind them.

......

Zhanqiao, Chief of Staff Weijie is reporting to Lin Xi: "Today, Weijie has been ordered to recruit 2,011 scribes, and the time is in a hurry, so I can't do a detailed screening, but I believe that most of them are good." What to do now, do as I am told by the present. ”

Lin Xi said: "Now that we have more people and a larger team, it is impossible and unrealistic to let me command them one by one, and I still want you to do more specific work, put forward opinions and suggestions, and even strategies." I'm not omnipotent, either. ”

Chief of Staff Weijie nodded yes, and then said: "Marshal Tu, the personnel are more mixed, and it may take a long time to produce results." Thinking so, I immediately sent three or four teams of 100 men to open the way to Eagle's Beak Rock. ”

Lin Xi said: "The lookout post on the hot air balloon just now threw down a note, saying that thick smoke was found about three or four miles to the east, and there may have been an exchange of fire, and the number of our advance team is not large." ”

Wei Jie said, "Is the Venerable Master willing to take the hot air balloon with the forwards? ”

Lin Xi said: "The Xuanyi has its own mast, and we are also expected to have a telescope, now there are only three telescopes in total, and the Xuanyi needs to set its own position according to the tide, this is our last hole card, and we must guard against it."

Now there is a pair of telescopes on the hot air balloon, which can see through the geography of mountains and rivers, military fireworks, and combat power.

But if the hot air balloon leaves the Xuanyi, it will bring two problems, the first is the supply of materials, which used to be communicated with the Xuanyi through pulleys, but now it must be organized by the ground.

Second, the buoyancy of the hot air balloon and the force of the wind blowing through it are insignificant compared to the Xuanyi, and the strength of the soldier's arm is huge.

Thirdly, the hot air balloon is heading towards the eagle's beak rock, and someone needs to pull it forward. ”

Wei Jie understood the specific use of the hot air balloon, and immediately felt surprised and happy, thought for a moment, and resolutely said: "Today, I think that if there is a hot air balloon to help, there will be three wins in this matter." ”

Lin Xi said, "Oh, let's hear it. ”

Wei Jie Says:

"This first victory, the hot air balloon suspended in the air, the volume is huge, the combat power is strong, has been called a conspicuous sign, the location of the hot air balloon, will certainly be able to warn the enemy, at least to ensure our safety for half a day, this so-called Wasion also.

The second victory, the hot air balloon stands high, sees far, and hits accurately, which can help protect our wasteland development team, avoid detours, improve efficiency, and avoid mutiny.

The third win, the hot air balloon buoyancy is huge, we open up the road this time, in order to transport materials, it is inevitable that some places are difficult to pass, a while also need to erect a pontoon bridge, if the hot air balloon is divided into two ropes, some road sections, can be hoisted operations, the so-called quick victory also. ”

At this time, Tu Xicai had already come over, and first praised: "Minister Yuan is really a master, at a glance, he can be so imaginative, thinking about Shengyuan, and the countryman is just like that." ”

Wei Jie said: "Marshal Tu has an overreputation, whether these can be completed or not, Yuan is just speculating." ”

Lin Xi said: "Hot air balloon buoyancy has to do work, and the requirements for meteorological conditions are more demanding. However, taking the risk of moving the hot air balloon into the team is still very positive. Do it! Before sunset, the defensive camp of Eagle's Beak Rock must be established, otherwise we will have no water or food tonight, and the soldiers will mutiny. ”

Lin Xi asked again: "How many people can the drinking water of the eagle's beak rock supply?" ”

Tu Xicai said: "I just asked the original Hongguanya militia Hongshan, he said that there are many rocks in the eagle's beak rock, they have not dug a well before, but occasionally there is a stream on the surface after the rainfall, there is a small brackish water swamp two or three miles to the south, the area is about one mile square, to the west is the direction of our here, the hilly and undulating terrain, there are some salt-alkali tolerant thatch, it is estimated that if you want to see water, there is no depth of twenty or thirty steps, it is impossible to take out water." ”

Lin Xi asked: "In the village where he lives, how deep is the well?" ”

Tu Xicai said: "It is a very old village, it is said that there is a water vein, but it is also more than ten steps deep, and when it rains less, the sea water will pour back, and the water will be undrinkable." ”

Wei Jie said: "The main reason for the eagle's beak rock is that the rock is difficult to excavate, and the rock does not absorb water, so it should be relatively easy to retain groundwater." It's just that in a hurry, we dug a well of twenty or thirty meters, and it was very difficult without tools. ”

Lin Xi asked, "What if there are tools?" ”

Wei Jie said: "If you have the tools at hand, you need a steel drill and a hammer, dig a circle four or five feet square, and then gradually go deeper, and you can go down four or five feet in a day and a night, it is not easy." ”

Tu Xicai gasped and said, "Wouldn't it take twenty or thirty days to take twenty steps like this?" ”

Wei Jie said: "Do you think that well water is the lifeblood." ”

Lin Xi remembered the drilling of later generations, but now I want this thing, there is a lot missing, thinking of drilling, Lin Xi suddenly thought of Zigong salt well, Zigong's salt well is the most famous, in fact, it is an invention, Shenhai well is chiseled by the traditional Chinese percussion type drilling method, and is still producing well salt, Shenhai well is a sign of the maturity of drilling technology in ancient China, and is an important milestone in the history of drilling technology in the world. Lin Xi vaguely remembered the record in "Tiangong Kaiwu Well Salt" - where the stone mountain in Shu is not far from the river, more can build a well to take salt, the salt well is only a few inches around, and its upper mouth is covered by a small bowl, and it must be ten zhang away, which is a halo letter. Therefore, it is very difficult to build wells. Its instrument controls the iron cone, such as the shape of the mouth, and its tip makes it extremely rigid, and it is chiseled into a hole to the stone mountain. Its body is broken with a bamboo rope and hangs this cone. Each of them is a few feet deep, and then it is connected with bamboo to make it grow. At the beginning of the zhang, or with the foot on the tip, such as the shape of the rice. If it is too deep, hold it with your hand and pause. The stone is broken into powder, and then the long bamboo is connected, and the hanging iron cup is dug up. The deep ones are half a year, and the shallow ones are more than a month, and they have to be accomplished by a well......

When Lin Xi took the children to visit the Zigong Salt Well, he also saw that there were ancient well salt production tools and equipment in Shenhai Well and Dongyuan Well, such as the crane crane, the bully frame, the cart, and the brine cylinder, all of which recorded the history of the well salt, and the local area even maintained a very low artificial salt production to meet the local pickle market.

This kind of derrick, Zigong people call it "crane", is used to dig small deep wells, repair wells, extract brine support, a salt well is equipped with a crane.

Because there was no steel, the crane made at that time had to tie a number of fir trees into wooden stakes, tie them with bamboo ropes, and then erect the bundled wooden piles at the wellhead of the salt well, and the wooden piles were connected to each other to form an "A" shaped derrick.

\/\/ Install the sky roller at the top of the derrick and the ground roller at the bottom. The sky roller and the ground roller play the role of fixed pulley, and the lever principle is used to lift and release the well drilling equipment and brine extraction equipment.

The height of the crane is mostly tens of meters, and a few are more than 100 meters. It is said that the highest crane in the history of Zigong is the Dadejing crane built in the Qianlong period of the Qing Dynasty, which is 113.4 meters high.

The crane has four legs, 12 wind strips for stabilizing the derrick are pulled around, and there is a gap in the middle of the crane support pile, which can not only save materials, expand the ground contact area to increase stability, but also facilitate internal ventilation to prevent decay.

On one side of the crane is a truss, also known as a stepping frame, which is erected from a log and is equipped with a "flower roller" to wrap the rope. Below is the manual pedal board, and the head at one end of the pedal board is connected to the file and other tools through the rope. During the work, several workers stepped on the board, using the principle of levers, the head was cocked, and the drilling tool relied on its own gravity to quickly impact downward, so that the rock was repeatedly broken.

\/\/ "Big cart" is a large wheel disc made of wood and bamboo, also called "pan winch", "ground car", is a power facility with the help of rope traction sinking tools or brine cylinders, composed of four parts: shaft, disc, brake and frame, and evolved from the row and cart of the early Dakou salt well. Its working principle is to fix one end of the bamboo strip rope on the cart, and pull the sinking tool or brine cylinder at the other end after being turned by the ground roller and the sky roller. At first, more than 10 workers were generally needed to turn the cart by manpower, and then it developed into the use of animal power, mainly cattle, and when I went to visit, I was already using an electric winch to provide power.

\/\/ The brine cylinder is the key equipment for the extraction of brine, is a particularly delicate thing, generally more than 10 meters long, slightly thinner than the wellhead, the diameter of about 10 cm of Nanzhu is selected, the bamboo is opened, and the check valve made of cowhide is installed at the bottom. When the brine cylinder enters the downhole, the valve is washed open by water pressure, and after the brine enters the cylinder, its pressure acts on the check valve to make the brine cylinder seal itself, and then the brine is lifted out of the salt well.

After lifting the bamboo from the ground, the process of opening the check valve with a hook and letting the brine rush to the brine bucket is the most impressive thing of the visit - of course, people generally see success, and the process and hardship of success, who cares?

In addition, there is a very special feature in the Zigong salt wells, because the salt wells that go deep into the kilometer often produce natural gas, so most of the salt wells in Zigong in ancient times can produce brine and natural gas at the same time. Nowadays, the brine resources in Zigong urban area are gradually depleted, and most of the salt wells that are still in production are mainly used to extract natural gas. They are able to build a decompression separation unit to extract natural gas.

\/\/ Multiple images rushed over, and they were distributed in all directions; Instead, Lin Xi's own consciousness swept along the trestle in the direction of the eagle's beak rock, gravel ground, hilly broken rocks, low alkaline water resistant shrubs, seasonal swamps, and the taste of thousands of substances was still radiating light......

Minister Wei Jie's words floated in again: "I think that the eagle's beak rock must have a certain water source, but it is not easy to mine." ”

Lin Xi's heart suddenly moved, and asked, "Where are the materials of the Queen Mother?" ”

Tu Xicai said: "I heard Jiang Chen say, it was actually a few caves, which were opened and refilled with earth and stone outside. ”

Lin Xi asked: "Then don't the locals hunt and collect medicine, they are not afraid of being known by others?" ”

Tu Xicai was speechless for a moment, and said after a while: "I haven't seen it in person, I guess they actually have some tricks." ”

Lin Xi looked at the eagle's beak rock again, trying to expand his sense of consciousness and touch, and suddenly felt something moved in his heart, among those feelings, there were sounds, smells, tastes, touches, color visions, and even some elastic feelings......

Lin Xi thought of water, and his consciousness was at a clamp in the first line of heaven, and suddenly he drilled into it, and the downward water veins became wider and wider, and then converged in the clay layer, extending to the south and west......

For a moment, it was like two kicks suddenly swept the ground, and the eagle's beak rock rose up, and the red and gray clouds were stacked on top of each other.....

\/\/ When is it a head?

When the thought came to me, the speed of the flight became faster......

At this time, Minister Yang Yuxiu's voice came: "Venerable Master, Venerable Master?......."

At this time, Hui Niang ran over and grabbed Lin Xi's shoulder and shook it gently: "Venerable Master, you have received your supernatural powers." ”

Lin Xi's mind suddenly appeared with a small blue Meng Meng Meng light spot, and he was very happy to say to another small pink light point: "Hey, hey, did you hear it, they have received the supernatural powers, they have known the supernatural powers."

Another little pink point of light said: "Cut~~, that's what you say, you really know the supernatural powers, can you say it at this time?"

In the blink of an eye, everything was gone, Hui Niang was babbling, Lin Xi took a long breath, and then asked, "Where did you go?" ”

Tu Xicai said: "When it comes to opening the way with a hot air balloon, our Xuanyi Army will march immediately. ”

Lin Xi said: "Very good, then let's do it." Hey, do you know the salt well in Zigong, Sichuan? ”

Tu Xicai said: "Well, I have heard of it. ”

Lin Xi said: "There are two kinds of wells in Zigong Yanjing, one is an open well, and the other is a small well. ”

Tu Xicai asked, "Venerable Master, what do you want to say?" ”

Lin Xi said: "When you arrive at the eagle's beak rock, you go to the first line of heaven, go to find a crack, dig down, and see if there is any water." Well, you can also look around, at least to solve the water that the eagle's beak itself drinks. ”

Tu Xicai said, "Eh, I know." ”

Lin Xi felt a little tired and said, "You guys work hard." I'll go back to Xuanyi first, we have to prepare something useful. ”

At this time, a herald ran in the distance, causing a commotion, everyone watched the herald come to the side, the herald ran to the position, turned over and fell off the horse, made a military salute, and then said: "The ministry to meet your lords, pass on the news of Jiang Chen's chief, the advance team met Mengyuan stragglers in Daliushu Village, there were more than 200 people, we sniped some of them, and set the whole village on fire, and then Jiang Chen's chief ordered the four scouts to set off to the direction of Eagle's Beak Rock first, and Song Yuan was taking the generals to follow up, In the end, Jiang Chen handed over the command to Ding Cong Baihu, and Ding Cong Baihu asked us to establish a blocking line from Ertan Village, and let Jiang Chen lead his own soldiers to break off the main army of Song Yuan. Jiang Chen asked the ministry to bring news, maybe there are still Mengyuan soldiers in that area, please pay attention to the Venerable Master and Marshal Tu. They will set up a cottage at Eagle's Beak Rock, block Meng Yuan, and wait for the rescue of a large army. ”

Tu Xicai was anxious when he heard it: "Sure enough, sure enough, I know that these bitches don't have a good bird." ”

When Wei Jie heard this, he gently pulled the palm of his left hand with his right index finger, and said cautiously: "I think the speed of the hot air balloon should be accelerated, and if necessary, we can abandon the trestle, which was originally an open space." We set up the Eagle's Beak Rock Base Camp, which would be enough to withstand tens of thousands of people as long as the drinking water problem was solved. ”

Tu Xicai said: "What about the Xuanyi? ”

Wei Jie said: "The problem now is that there is no charcoal, no sails, no sufficient food, and of course, communication is also a problem. But what if we make up these three things? As for communication, we can also use pyrotechnics to send messages. Moreover, there are also supplies on the outer islands, as long as the Xuanyi is replenished with personnel and sails, a camp can be established on the outer islands. Each other is a horn trend. ”

Tu Xicai asked: "But from the eagle's beak rock to the trestle, there are four miles away, and the trestle to the Xuanyi is also hundreds of steps!" ”

Wei Jie said: "We have nearly 20,000 soldiers, lined up in a row, carried by human chains, and can be replenished in a few hours, besides, we don't need to supply now, we can supply at night, at that time, the sight is not good, they will not dare to approach." ”
