"So is the wood problem easy to solve?" Du Yande pointed to the automatic tree chopper that was still cutting trees outside. "With that guy here, it shouldn't be too difficult, right?"

"Compared to technology, the problem of wood is not so troublesome, and Xiao Jing has led people to build an earthen kiln near the riverside clearing, and dry the wood by burning the branches and leaves and slowly smoking. Although the degree of drying varies and the efficiency is not high, the wood is still usable. We approached the construction team, and the construction team said that there had never been a hydropower station, and now there are a few drawings of small hydropower in the countryside in the big library. Yuan Fang wiped the itchy part of his face a little depressedly. Carter didn't understand it for a long time, and now Xie Mingfang is translating and explaining to him. But Xiaofang said that there is no big problem with these, as long as the pressure pipeline problem is solved, it will definitely be done. ”

"And how long do we need pressure piping?"

"It takes about more than 80 meters, and we also found Xiao Jing, and the wood processing team said that we can find a way to do this." Pan Dai flipped through the notebook in his hand, "But someone showed me a CAD drawing they just designed, I checked that there should be no problem, you can take the drawing to the wood team and see if you can get it done." As he spoke, he took out a CAD printed drawing from it and gave it to Du Yande.

"I'll ...... Who drew this? The material on this is accurate to the millimeter, and the angle is accurate to me, isn't it a joke? I don't have a CNC sawmill again. Xiao Jing took the drawing and almost jumped. We're all doing it by hand. These sawmills are also ordinary, and it is impossible to make such accuracy. ”

Du Yande did not expect such a situation at all, in the old time and space, he only needed to take the drawings and hand them to the wood processing factory, and then directly receive the finished product, but in this new time and space, it has become an "impossible task". He couldn't help but look at Xiao Jing's face with a thin layer of sawdust sticking to his sweat, "Then what should we do?" ”

Xiao Jing wiped the sawdust from his face, "I can't guarantee the time for this, we have to try it while doing it, it's too difficult to ensure that this thing doesn't leak." You do this, let them dig the channel first, and I will set up a research team here to start solving this problem. ”

Subsequently, the construction team that received the instructions began to excavate a two-meter-deep and two-meter-wide waterway according to the drawings given by the power team and the route determined by the on-site survey. But the construction team can't find an excavator at hand now, and according to the military group's estimates, I don't know how quickly these Wu Dynasty troops will react, but they would rather plan for the worst than wait optimistically for the enemy to appear outside the undefended gate. All the excavators are racing against time to build the protective wall of the beach camp. This had to be done by manpower to excavate the 80-meter-long pressure pipe tank.

The human resources team soon sent two ordinary labor team members. Many of these people used to be white-collar workers or assembly line production personnel, and now they don't look naïve at all with hoes and pickaxes.

As the excavation work reached a stony section, the ordinary labor team began to be unable to do it, and the hoe and pickaxe smashed it was just a white spot, and this place was quite small, about ten meters, because it was a whole stone, and it was impossible to get around. Because there is no air compressor and air pick, there is no way to break such stones, and the use of percussion drill will not only seriously damage the life of the drill bit and affect the inventory of the percussion drill bit, but also the efficiency is too low. Soon the solution came, with a farm truck from the trestle in front of the Dongfeng next a large yellow box, the skull logo on it made everyone shudder, and when it was transported to the side of the channel, the two traversers in charge of transporting it carefully put the box on the ground, and after opening it, the traversers who surrounded it couldn't help but gasp, "Isn't this TNT?" Looking at the long strips of cylindrical paper lying in these boxes, someone asked curiously.

Shi Li, who was in charge of transporting the large box, shook his head, "This is ammonium wood explosives, made of ammonium nitrate, and our chemical team is made of them in the freezer at the bottom of the ship. ”

"When I went, I thought the ammonium nitrate fertilizer was for the agricultural group."

"Imagine beautifully, they have compost, and our ammonium nitrate is to be used as explosives."

"But this thing is not very powerful, and it can't cause much damage if it is directly used as a grenade."

"That's true, but now these are not intense, and I don't dare to make ...... to be honest" Shi Li smiled and shook his head, "This kind of thing is often used in blasting projects, if it is used to load grenades or mines, it is not bad, during the Anti-Japanese War, the New Fourth Army and the Eighth Route Army also purchased ammonium nitrate to be processed and used as a weapon, this thing has several benefits, the power is enough, the sensitivity is low, and the general collision will not make it explode." ”

"So what are you so careful about? Look at the action of putting the box first, as if serving the little daughter-in-law. The onlookers laughed.

"This thing will explode, if it really explodes, the parts of our body will definitely be able to fly three hundred meters away, okay?" Shi Li replied a little depressed. This sentence immediately made the traversers who had surrounded the three layers inside and the outer three floors run more than halfway.

Lin Shenhe, who was next to him, said with a smile, "We don't have any detonating charge now, mainly because there is no mercury, and we can't make thunder mercury, but black powder is also a good explosive charge. However, you must know that ammonium wood explosives are very susceptible to moisture, not to mention this seaside, so you can only say how much you can use to make as much as you want. If it is not used up, it should be returned to the cold storage for preservation. ”

"What is ammonium dynamite?"

"Cut, of course, it is made by mixing ammonium nitrate with some wood powder, which is more efficient."

"Wood powder? Is there wood flour here? A traverser with a relatively long reflection arc suddenly came out of nowhere.

There was a sudden silence all around, and then there was the sound of "squeak-squeak-squeak" of woodworking equipment not far away, and everyone suddenly burst into laughter. Even the person who asked the question let out a hearty laugh.

Next, Lin Shenhe volunteered to instruct the construction team to use a small gasoline generator to generate electricity, and use a percussion drill to punch holes in the stones. After it was ready, he and Shi Li carefully installed the explosives, and then at the request of the military team in charge of vigilance, all the people on the beach stopped their work at hand to avoid accidents caused by the sudden loud noise, and all the people nearby put on steel helmets and hid behind various covers, and then Lin Shenhe lit the fuse, and then ran all the way to the back of a shelter, waiting for the earth-shattering sound.

Shi Li nodded at him and shouted, "Old Lin, how long is the fuse?" ”

"It should be two minutes."

But two minutes went by in a flash, then two and a half minutes, three minutes, three and a half minutes, four minutes......

"Are the people in your chemical team reliable? The two-minute fuse is now almost five minutes old and has not yet responded. "A traversal lay behind a mound of dirt for a while, counting the time and feeling almost uncountable.

"Strange, didn't this lead detonate?" Shi Li couldn't help but look up at the place where the explosives were planted. At this moment, there was a sudden explosion in the distance, and the ground was beating with a dull roar, and the branches and leaves on the treetops of the woods on both sides that had not yet been cleared were shaking wildly, and many people were dizzy and their internal organs were churning. Fragments of earth and wood flew through the air, and then fell crackling within a radius of 100 meters.

With an exclamation in the ears of the buzzing sound, many people ran to the river to look lively, and many fish in the river were stunned by the explosion and were floating on the surface of the water and slowly flowing down the current into the sea.

"The power of your explosives is amazing!" Li Jieqi, who was in charge of guarding on the side, said loudly to Lin Shenhe with a smile.

Lin Shenhe plucked out his ears and shook his head again, "The power is really good, let's go and see the results of the blasting." ”

The person in charge of the construction team walked to the stone section with Lin Shenhe. A huge stone here has been blasted into many small pieces of about half a meter, and some of these pieces have flown out of the ditch and scattered within more than ten meters, but most of them still fell into the ditch, smashing the ditch that had not been cleaned up before beyond recognition.

"Who?" There was a loud shout nearby, followed by the sound of a bullet being loaded. "Stop, shoot if you don't stop."

Everyone looked over there in amazement, and then there was the sound of warning shots fired in the air.

"It's none of our business over there, let's continue." The construction team took the lead and jumped down the ditch and began to clean it up.

Li Jieqi hurriedly ran over to check what was going on. On duty there was a 212-year-old armed police soldier on the former border anti-smuggling boat, who was wearing a camouflage uniform and holding his 1 August rifle in his hand, looking very vigilantly into the woods.

"What's going on......" Li Jieqi didn't know the name of the fighter, "are you?" ”

"I'm Xiao Lihua, just now someone over there probed his brain to look this way, I shouted, but he turned around and ran, so I fired a warning shot, but he still ran too fast, I didn't catch him." Xiao Lihua couldn't help but look over there with some disappointment.

"Do you see people clearly? Not one of ours, right? ”

Xiao Lihua replied very simply: "Impossible, our people will not go into the jungle at will, they will lose their way." ”

"Then I'll leave it to you, and I'll have to look around."

"Okay." Xiao Lihua put the rifle on his shoulder and began to guard around again.

The commander of this beacon tower was originally carrying a dozen taiding when he fled in the morning, but after taking the initiative to attack the reconnaissance group of the three pirates, he suddenly became the commander of the light pole. He didn't dare to return to An Yuncheng like this with a black eye, and Wu Wenshan, who had been thinking about it for a long time, decided to go back to the beacon tower first to see what the situation was. Relying on his familiarity with the road conditions and terrain, he actually passed through the mobile posts of several military groups without any obstacles, and was not detected at all. Approaching the beachhead, he was directly stunned by the situation on the beach. The little thing flying in the sky that he had seen before didn't shock him too much, but at this time everything on the beachhead made him dumbfounded.

A huge trestle stretched long into the sea, directly to the side of the huge ship, and the steel arms of the ship were placing huge boxes one after another on the carts that could run around on their own without the tugging of oxen and horses, and the carts were running fast on the trestle to transport the huge boxes to the beach.

The beach was full of people, and he suddenly found that his captured men were being naked on the beach for medical examinations, and he had no idea why the pirates had stripped their men naked, and several of the wounded men were naked and bandaged, and they seemed to be being treated. In the few battles he remembered with Annan, he had never treated the enemy's wounded, and it was already extra generous not to cut off their heads for war merits, so why did he treat the enemy's wounded?

Looking around, he was frightened again, and the huge monsters stretched out their long arms of steel, some directly breaking the trees, some digging up the roots of the trees, some pushing the soil to the side, and some of the carts with huge iron rollers crushing the soft mud into a flat ground. He'd been on this beach for almost six years, and the terrain was absolutely familiar, but after only a few hours of escaping, the beach and the jungle by the beach had completely changed. What's more, since these pirates are building so much, they naturally don't come here to loot and leave, this is obviously building a city! How is this good? Not to mention that those pirates all have sharp firearms and are extremely skilled in fighting, just the various terrifying mechanical monsters on this beach, even if they bring the Heavenly Empire soldiers, they are also mantis arms to block the car. Thinking of this, he hurriedly turned around and wanted to run, but was frightened by an earth-shattering explosion and fell to the ground, when he trembled and got up from the ground, just in time for Xiao Lihua to also come out of the cover, so the above scene appeared. Relying on his familiarity with the terrain, he hurriedly ran wildly through the jungle, and ran for several miles before he dared to stop and look behind.

Wu Wenshan, who stopped, was out of breath, and his stomach felt a tumult, and he couldn't help but vomit while holding on to the trees beside him. After vomiting for a while, he stopped and began to think about what to do. Back to the Pingnan Thousand Households near Anyun City to gather troops to fight back? However, more than a dozen of his subordinates attacked three pirates and were completely defeated, what role can these more than 100 soldiers and hundreds of peasants play in the same military household? It is estimated that if you can't rush nearby, you will be killed on the road, and then the people behind will scatter in a hurry. Why don't you go to Dawu Annan to supervise the Beihai Coastal Defense General to find the commander General Liu Chuanzhi? This army of Annan is under his jurisdiction regardless of sea and land, and since he has to face such a large army, he must only turn to General Liu Chuanzhi for help. But he couldn't rush to General Liu, this was not in accordance with the rules, and he would be dealt with by military law, so he still had to go back to An Yuncheng first, and let the county order send an urgent document to General Liu, so that they could coordinate the transfer of troops to drive away this group of pirates. Thinking of this, he hurriedly checked that there were no injuries on his body, and hurriedly looked in the direction and rushed in the direction of An Yuncheng.

…………………………

"Take a break, Brother Bei." Yang Mu Qin panted, carrying a large bucket on his back, and walked slowly with his rifle one step at a time.

He Ya looked at it, and hurriedly stabbed the northern latitude with his hand, and Chongyang Mu Qin nu his mouth.

Beiwei turned his head to look, and saw that Yang Muqin was still panting there with a rifle, and walked back with a smile, "Xiaoyang, let's change one?" ”

Yang Muqin looked at the backpack that Beiwei and He Yayun were carrying, and shook his head firmly, "Don't change, you are carrying too many things, heavier than mine, you are all really soldiers, and I haven't exercised these, it's not fair." ”

"Fair?" Beiwei smiled and patted him on the steel helmet, "Xiaoyang, we also practiced it like this back then." Let's go, I don't know how far ahead I am. ”

"I don't think we should be far away." He Yayun said after watching left and right for a while. "You see, the smoke in front of the beacon tower is gone, and it stands to reason that the city they need to notify must be near here."

"Really?" Yang Muqin came to his senses, picked up his rifle and followed He Yayun to continue walking, which was completely different from the half-dead appearance before.

"Do you still have this strength for a while?" Before He Yayun finished speaking, he easily brushed aside a bush in front of him, as if opening a curtain, and a city wall appeared in front of him in the distance.

It was a medium-sized city, and a few glances at northern latitude estimated that the population of the city was at least 2,000.

"A city of 2,000 people is also called a medium-sized city?" Yang Mu Qin sat on the mud ground by the bushes, he was not worried about being found now, this guy was now wearing a camouflage uniform, with a camouflage bucket behind him, and even the helmet elbow pads and knee pads were camouflage, not to mention that the city wall was a hundred meters away from him, even if it was only a hundred meters, the bushes behind him would never expose him as a background.

"Do you think it's time and space when we came, and there are hundreds of thousands of people in the city at every turn?" He Yayun smiled and half-knelt on the ground and took off the backpack on his back. "Ancient cities can generally have fifteen or six hundred people is not a small city, and before the large-scale use of cannons and bombs, the defense of ancient cities mainly relied on city walls, and expanding the population will inevitably expand the protection scope of the city walls, and it is not easy to repair or build a new section of the city wall, so ...... Then there will be Zhuangzi. When we rescued Yang Minghuan a few days ago, it was a typical Zhuangzi of the assault, which was just a small town surrounded by a relatively small city wall. ”

As he spoke, He Yayun took off the shovel from his backpack and began to dig a hole in the ground.

"What are you digging here?" Yang Muqin didn't know what he was doing, and hurriedly asked.

He Ya made an analogy with a shovel, "A shelter, first dig a pit more than a meter deep, and then set up observation equipment inside. Xiaoyang, you go find a tree, a taller one, and set up a communication antenna on it. ”

"Communication antenna?" Yang Muqin asked curiously. "Which one? How do I set it up? ”

This communication antenna is a "special design" of the communication group, with a directional transmitting and receiving device, and at the same time a short-wave communication radio station as a backup, in order to ensure the power supply, they carry a battery and a manpower generator. The radio station is not powered by a few No. 5 batteries, and three people take turns turning the generator rotor on the generator to provide the power supply. In order to exercise Yang Mu Qin, Beiwei didn't move at all, and only commanded Yang Mu Qin to operate on it. Poor Yang Muqin, a guy who had just learned to climb a tree, was forcibly asked to climb a pine tree nearly 30 meters high by Beiwei, and set up an antenna on it, which was blown dangerously by the wind, and it took a full hour and a half to install the communication antenna and the attached solar cell.

By the time Yang Muqin and Beiwei returned to the shelter, He Yayun had already dug a prototype of a large pit two meters wide and three meters long, with a relatively high observation position in the front, and a drainage ditch was dug in the rear of the area where rangefinders and telescopes were set up, and even a grenade tumbling groove was dug in the back. Beiwei and Yang Muqin were surprised, "Xiaohe, your observation post is quite regular." Where did you learn this? This is the professional skill of the field army. Where did you learn it? ”

"Hehe, I learned it when I used to read the information, but I dug it informally, don't laugh at me."

"This shelter of yours is very well dug and very good, just cover it with a tarpaulin and cover it with branches and leaves." Beiwei said as he began to erect a camouflage net next to the shelter.

It didn't take the three of them a few minutes to set up the shelter, and from twenty meters away, it was a relatively tall bush. Even if you walk within five meters, you can barely see inside, but this is an inclined plane, and people walking up in front of you will be spotted from the bottom of the mountain, and behind it is a relatively dense bush, which is difficult for people to cross. A small gauze tent was erected in the shelter, this place is in the tropics, and the night temperature measured by the meteorological team on the Dongfeng yesterday was also 212 degrees, a little blanket is enough, a set of temperature zone sleeping bags and moisture-proof mats, as long as you don't get bitten by mosquitoes.

"Record," Beiwei was lying at the observation port, holding a telescope to observe the situation on the city tower and the city wall, and began to dictate the observed situation, Yang Muqin was holding a small notebook on it and recording it with a pencil. "Now the time is five o'clock in the afternoon, the circumference of the city wall is about five kilometers, the residents in the city are estimated to be about two thousand people, the patrol on the city wall is being strengthened, about a hundred people, the weapons are rudimentary, there are two cannons on the east city gate, look at the size should be a tiger squat cannon, there is no army stationed in the gate, and there are only two guards at the city gate to defend."

"Brother Bei, shall we go and attack?" Yang Muqin was impatient at this time, and was slapped on the steel helmet by Beiwei. "Are you stupid? Now we are all wearing such clothes, if we rush over, we have to be splashed with dung, people will think that we are demons and monsters, and we may be recorded in "Strange Tales of Liaozhai" in the future. ”
