Liu Fei's concentration fascinated everyone, and even Wei Xiong's gaze was taken away from Tali.

It's a lesson, a hunting lesson.

"This is one of the smallest types of space ropes currently in use, and this kind of rope is made of multiple independent threads. In this way, they are not cut off by the same particle, and even if one is broken, the rest are still connected to the load. In this regard, the Federal Research Laboratory of Mankind and the National Reconnaissance Bureau of the Seven Star Fields jointly created a hollow band of Spectra fiber material with a diameter of 2.5 mm. In July 1996, such a hollow belt with a length of 4 km and connected to two satellites was launched. So far, it has been in orbit in space for almost 3 years without breaking......"

Liu Fei explained the history and data of the space rope, and generally used a laser to cut the space rope into sections.

"Why cut the space rope?" Mer's intellectual curiosity was many times stronger than that of the others, and she immediately asked her own questions.

"These space ropes have a very large carrying capacity, and they can be used to stop the charge of the gladiator heavy ironclad cavalry, so that they cannot rampage through the streets of Weijiaji."

"Use it to stop the cavalry?!"

Mei'er and the others glanced at each other, and there was an incredible expression on their facesIn fact, not only him, but everyone had a look of surprise on their faces, after all, using this thin rope, which was about the same as a hair's hair, and could not be seen clearly with the naked eye, against the gladiator heavy ironclad cavalry, this in itself was unbelievable.

"Wei Xiong, you try to rip them off and see."

Liu Fei didn't care about everyone's doubts, he had already cut enough space ropes, and now, he was preparing a miniature smelting furnace.

The miniature smelting furnace is one of the necessary equipment on the mecha, and its main role is to use it in an emergency, for example, when a small part of the mecha fails and parts are needed, the miniature smelting furnace can produce those small parts of small size to improve the survivability of the mecha.

Of course, now Liu Fei is not repairing mechas, but making some tools.

"Wow! It's really sturdy! Just when Liu Fei was assembling the miniature smelting furnace, Wei Xiong picked up a thin space rope and pulled it with all his strength, the rope did not move at all, but Wei Xiong's palm was strangled out of the deep groove, there is no doubt that if he used no more force, his palm would be cut by the rope.

"It is impossible for all the people in this room together to tear this rope, for they have a pulling force of at least ten tons, and of course they can be easily cut, with a sharp edge, with a slight force, they can be cut in two...... Now, I tell you how to stop the gladiator heavy ironclad cavalry with this rope...... Wei Xiong, Manny, we saw the gladiator heavy ironclad cavalry yesterday, what height were they on their horses? ”

"That...... It's about two meters and five to three meters. Wei Xiong hesitated in reply, and Manny nodded.

"More than two meters five, for sure?" Liu Fei asked again.

"Yes, it's definitely more than two meters five!" Manny and Wei Xiong glanced at each other and nodded affirmatively, they had seen it with their own eyes.

"Yes, the visual inspection is more than two meters five, and the height of the war horse is one meter six to one meter eight, that is to say, even if the cavalry is lying on horseback, the height is more than two meters, according to my understanding of the residents of Wei Jiaji, there are almost no people who are more than two meters tall, well, then, let's limit the height to two meters, you think, if we fix this kind of rope in those dense lanes of Wei Jiaji, the height is limited to between two meters and two meters five, if the gladiator heavy ironclad cavalry is charging at high speed, What happens if you are suddenly blocked by a rope? ”

"Ah......h

Everyone let out an exclamation of surprise, and then suddenly realized, it is conceivable that when the gladiator heavy ironclad cavalry suddenly tripped over the space rope that was barely visible to the naked eye while galloping wildly, it was definitely a disaster, and the ferocious momentum alone was enough to make them suffer.

"However, those streets are either lined with bluestone walls or tents, and although there will be some trees to use, there are more places where ropes cannot be fixed." Mei'er was as careful as a hair, and immediately discovered the loophole in this plan.

"Yes, I'm going to solve this problem soon."

Liu Fei opened the light brain of the miniature smelting furnace, the light brain exuded a charming brilliance, under the flexible jump of Liu Fei's ten fingers, the light brain shot out a holographic image, which was a spiral metal object with a ring at the end.

"You see, this is a hydraulic screw, as long as there is a micro hydraulic machine, it can easily drill into stones, wood, cement, and then, put the space rope into the ring at the end of the end, a little ambush is completed."

"However, we don't have the microhydraulics you said." Wei Xiong stared at the circulating hologram with a pair of eyes, and couldn't help but touch it with his hand, and the palm of his hand immediately penetrated the light curtain, and people were amazed.

"Yes, I have exactly three of them." Liu Fei pressed the button of the light brain, and the exit of the miniature smelting furnace immediately sent out a spiral-shaped hydraulic nail, about the size of a thumb, shining with a metallic charm.

Liu Fei summoned a miniature hydraulic machine from the space button, which was a simple machine with an arm length that could be controlled with his shoulders and palms, and Liu Fei did an experiment on the spot, pressing the hydraulic screws silently into the green bricks on the ground.

"This screw is very strong and has been integrated with the green brick, because there is a fine hollow in the middle of the nail, and when the hydraulic impact rotates, it will produce a certain expansion, increasing the friction with the green brick......"

"Isn't that what we can do now?" Wei Xiong was immediately overjoyed, grabbed the miniature hydraulic machinery and was about to go out.

"No, we don't have enough expansion screws, this micro smelting furnace is a temporary equipment, and it relies on air circulation cooling, which is very inefficient, we have to wait slowly, and we need a perfect plan......"

"First of all, we want to tell you that because Weijiaji is too big and has a large population, we don't have enough manpower and equipment, so it is impossible for us to protect everyone, and when the time comes, there will definitely be casualties, and we must be mentally prepared......

Everyone glanced at each other, and the excitement just now disappeared invisibly, and a heaviness spread in the living room.

"Now, we have to identify a few streets as priority places to protect, first of all, these streets must have at least a few conditions, for example, there are trees that are convenient for ambushes, hard walls, and most importantly, fire prevention, when those cavalry come in, in order to create panic and facilitate slaughter, some people will be forced onto the streets, and when the time comes, they will definitely set fire everywhere, and the streets that can prevent fire are one of the necessary conditions!" Liu Fei had a serious face, among all his plans, fire prevention was the most critical one, if those cavalry were allowed to burn the company camp, everything he had prepared would be empty talk.

The crowd began to draw maps on the makeshift workbench in the hall, street by street, but the expressions on Maniwechon and Tali on their faces became more and more solemn.

"What's wrong?" Liu Fei felt that the atmosphere was wrong.

"The streets identified are all areas for the wealthy." Mei'er said lightly.

"The poor will run to the protected streets, that's the instinct to survive."

Liu Fei sighed, this is no way to do it, in Weijiaji, only those rich people's houses will be built sturdily, a large number of masonry structures, and fire and theft prevention will be taken into account, those slum residential areas, are all dilapidated tents, a fire can burn through.

"Knock knock ......"

Just when everyone was busy tidying up, there was a quick knock on the door, and everyone was shocked, if the police came to the door at this time, all plans would come to naught.

"It's a friend." Liu Fei motioned to Wei Xiong to open the door.

Sure enough, it's a friend!

Wei San poured into the hall with dozens of thieves and rat-eyed guys, and when he saw that the hall was full of metal equipment, his eyeballs were about to burst out, they were all experts, so he naturally knew that these metals could be said to be priceless.

With the addition of Wei San's group, the work efficiency has improved a lot, compared to Manny, Wei San's group of people think that for professional reasons, they are more familiar with every corner of Wei Jiaji than them.

When they learned about Liu Fei's plan, everyone excitedly put into their work, drawing the streets of Weijiaji in more detail, where there are trees to use, there are bricks and stones to use, and those places are easy to ignite, they will mark them clearly.

At two o'clock in the morning, dozens of people divided into groups and began to set up ambushes on the streets of their choice, their division of labor was very detailed and their goals were very clear.

In this preparation process, Liu Fei used some ready-made machinery to assemble a multi-functional light energy punching machine, but, unfortunately, this punching machine is a bit large, weighing hundreds of kilograms of energy alone, and manpower cannot move it at all.

Of course, this was not difficult for Liu Fei, because, when he entered the door, he saw a carriage, and in the midst of Tali's protests, the rather luxurious carriage was modified by Liu Fei and equipped with the light energy punch that looked a little ugly.

……

Tali's house is the base camp, and the miniature smelting furnace is still working, guarded by the thoughtful Mei'er, who is mainly responsible for opening the door and providing Wei San and them with a steady stream of hydraulic screws.

Liu Fei and Tali drove the carriage equipped with a light energy punch to go out, and let Tali drive the carriage mainly to avoid police investigation, after all, this carriage belongs to the patriarch's family, and everyone in the Wei family knows this carriage.

The we're quiet and serene in the early hours of the morning, with the rustle of leaves in the breeze and the occasional sound of sleeping from the houses on either side, no one knows that it was a stormy night and a bloody massacre would befall every corner of the city......

"What's the use of these holes?"

Tali was a little impatient, she thought that following Liu Fei was something earth-shattering, and she knew that it was to use that inexplicable machine to leave small holes in the street one by one, which made her feel bored.

"They are able to stop the cavalry."

Liu Fei didn't look up, he kept manipulating the miniature light brain in his hand, measuring the distance between those holes, his expression was focused and cautious, these holes on the ground will be the key to improving the survival rate of residents, and their role is likely to be far greater than those space ropes......

PS: This month was ready to break out wildly, but because of the onset of eye disease, the surging momentum disappeared, after a few days of adjustment, I finally found a little feeling, there are 15 days left in this month, look at the performance!
