doomsday survival

Chapter 288
After 50 years of vicissitudes, the industrial park has been surrounded by trees, and the only one without many trees is the old road leading to the outside world from the industrial park.

Although the cement pavement has long been weathered, because there are steel factories in the industrial park that often run trucks, the roadbed at that time was very solid. Only in the gaps between the cement boards are there some tenacious weeds and short Trees dotted it, and the rest was bare.

Zombies are not without a little intelligence. Even if they want to come, they will not give up this convenient road and trek in the jungle instead.The zombies in the old district that was blown up before proved this point. At that time, apart from the old road, there was no trace of zombies walking in the surrounding jungle.

Of course, if it was a large-scale zombie attack, the surrounding jungle would not be able to stop them from advancing, just like in the Xiaoxing'an Mountains, the virgin forest did not cause too many obstacles to the zombies.

But in general, the old road is definitely the top priority of defense.Shi Jian and Feng Kuang discussed in the middle of the night, and they both agreed that as many landmines as possible should be planted here, and the surrounding woods should not be less, but the number is far less than that on the road.

All work stopped today, except for the women in charge of logistics, everyone else came to that road with Shi Jian, preparing to add a defense to the industrial park.

Although Shi Jian and Feng Kuang had made a plan last night, the first thing to do now is not to lay the mines immediately, but to test the performance of the mines first.

The landmines designed by Shi Jian use trip triggers, just like the landmines in the movie "Landmine Warfare" that "don't pull the string if you don't see devils".And the main target to deal with is zombies, so he also used jumping mines.

After this kind of landmine is triggered, the fuse first ignites and launches explosives, and the real explosion occurs after the landmine is pushed up to a height of more than one meter. The main killing parts are the human head and chest causing damage.

Because the weakness of zombies is only in the head, this kind of landmine is extremely lethal to zombies, and in order to increase the lethality, when Shi Jian designed the shell, the pre-explosion plates were also designed densely, basically Zombies have no chance of surviving.

This design has brought a lot of trouble to Fengkuang, because this kind of explosion method is very particular about the amount of charge and the delayed fuze.In order to know how much explosives to load to send the landmines to a height of 1.5 meters and effectively kill zombies, Feng Kuang conducted more than one experiment on this, and finally mastered the appropriate amount of explosives.

Because of this, the shells of the mines originally designed were sent back by Feng Kuang because the space of the launching part was too large, and Shi Jian asked Shi Jian to redesign and cast them.

The propellant dose has been mastered, and the time-delay fuze has also been researched, but the first batch of landmines has not yet undergone a real test.In fact, it is not only landmines, but also grenades. If the old military workers in the old era knew about this situation, they would probably be so angry that they would turn from zombies back into humans. Let them teach these two people a lesson first.

The reason why there is no experiment is that Shi Jian has been busy with iron smelting these days and has not spared any free time.The second is that Feng Kuang is quite confident in himself. In his words, a small fuse will not stop him, and he will never let a grenade explode in his hand, and a landmine explode on the ground.

Having said that, when it was time to plant the landmines, both Shi Jian and Feng Kuang decided to try it out first.

The test site was chosen on the old highway, and the first thing to test was the grenade.Even though Feng Kuang said that the fuse used by the grenade has a ten-second delay time, which is enough for people to throw the grenade, Shi Jian did not dare to hold it in his hand for the first test, but chose to operate it from a distance.

Shi Jian's method was very simple. He asked someone to clear a piece of snow on the road to expose the concrete road below, then poured some water on the road, and put the bottom of the grenade directly in the water.

It was already mid-December at this time, and the winter without the greenhouse effect was extremely cold. It was almost the season when dripping water turned into ice. The grenade was put on it for less than a minute, and it was frozen on the road.

Then Shi Jian placed a thick wooden board on the left and right sides of the grenade, one meter apart, to test the lethality of the grenade, but the front and rear directions were left empty, to test how far the shrapnel would be blown. , to determine whether this batch of grenades is safe.

Shi Jian held the grenade with his hand and pulled it twice. Feeling that it was firmly fixed, he tied the pull cord of the grenade with a thin rope and extended it to the old fence of the industrial park tens of meters away. In order to block the wall, he also specially frozen a fixed pulley at the foot of the wall and the top of the wall, so that the direction of the cable can be changed.

Shi Jian looked at Feng Kuang nervously, and asked, "Isn't there anything wrong with this distance?"

Feng Kuang nodded and said, "Don't worry, there is still a wall blocking this."

"Uh," Shi Jian was stunned for a moment, and asked, "Old Feng, to be honest, are you sure that you don't blow it too far, people can't throw it that far anymore."

Feng Kuang gave Shi Jian a sideways glance and said, "How far it can be blasted is not my problem, but your problem. All I can do is fill the grenade with explosives, and the rest is a problem of your design."

Shi Jian hesitated when he heard the words, as if comforting himself, he said: "It should be fine, I designed them according to the size of the grenade we use, there are finished products, there will be nothing wrong."

"Whether it's okay or not, pull it quickly." Feng Kuang patted Shi Jian's shoulder hard.

With Feng Kuang's shot, Shi Jian, who was already nervous, subconsciously pulled the string in his hand, but he didn't know it. Ten seconds later, the grenade over there suddenly exploded.

Shi Jian watched helplessly as a red light flashed, and then there was a loud noise, shaking the echoes in the mountains and forests.The snow around the grenade flew around suddenly, and then was sucked back again because of the sudden drop in the air pressure at the center of the explosion. The white snow and black smoke mixed together, presenting a strange beauty.

Because the grenade exploded on the ground, the bottom of the two thick wooden boards used to test the power suffered the most impact. They shook twice during the explosion, and then fell to the middle almost at the same time. After the tops hit together, they pushed the bottom Slide to the sides, and finally stop there because of the snow, forming a "herringbone" shape.

Feng Kuang stood up, patted Shi Jian on the shoulder, and said, "You are awesome, I squatted down, and you are still watching."

Shi Jian shook his head and asked, "Did I pull the string just now?"

"I'll go! You didn't know you pulled the string after playing for a long time, I thought you were brave." Feng Kuang almost fell off the shelf by the wall.

Shi Jian was afraid for a while, calmed down, and then ran over to check the situation, Feng Kuang and others also ran over together.

From the traces on the snow, it can be seen that the shrapnel was blown to a distance of about ten meters. It seems that this grenade is relatively safe and will not cause harm to the thrower.

The middle and lower parts of the two wooden boards were filled with shrapnel, especially the bottom. The shrapnel exposed a corner and almost penetrated completely, and the bottom was blown to pieces. It seems that the power of this grenade is indeed not small. .

Shi Jian took a grenade, weighed it up and down twice, and said, "Go, go back and try again."

Returning to the wall again, Shi Jian rounded his arms and threw the grenade out vigorously. The grenade flew out for about 30 meters and then fell to the ground. It continued to roll for a certain distance before it exploded. That is about ten seconds. It seems that Feng Kuang has mastered the time very well.

"Yes, I guess they can throw a distance of more than 20 meters, and their own safety can still be guaranteed." Shi Jian was very satisfied with his throw and said to Feng Kuang.

"Well, let's make another batch of grenades later, those things can be thrown far, and it is estimated that throwing them 50 meters will not be a problem." Feng Kuang suggested to Shi Jian.

The reason why the grenade can be thrown far is mainly due to its shape and center of gravity structure.The grenade has a longer torque, the center of gravity is closer to the outer ring, and the spiral energy storage and acceleration effects are better. At the same time, the grenade head and wooden handle also have the effect of spiral stabilization. Compared with grenades, it can be thrown farther and has higher long-range accuracy. good.

Of course Shi Jian also knew this, and immediately nodded in agreement: "Okay, I will make another batch of grenades later, so that there will be everything at close range and without distance."

After the grenade test was completed, everyone began to test the mine immediately. It was still the same as the test method of the grenade. After the mine was frozen on the ground, thick wooden boards were placed around it at different distances in the upper, left, and right directions. Only the direction below the mountain was left empty. surround.

Because the power of land mines is not comparable to that of grenades, Shi Jian directly hides behind the wall and pulls the wire in his hand.Without any delay, a softer explosion was heard first, followed by a much louder bang, which made everyone feel their ears buzzing non-stop.

When everyone recovered, Shi Jian took everyone to see the explosion site. They saw that the upper parts of the three boards were covered with shrapnel, and the board one meter away from the mine was blown to pieces.Seeing that the shrapnel flew out at a distance of nearly 20 meters, Shi Jian and others were extremely shocked.

As an earth mine, Shi Jian is quite satisfied with such power.Otherwise, I'm afraid he will have to look for scrapped arsenals, even where there may not be landmines, because the use of such weapons has long been prohibited by international conventions.

After the experiment, Shi Jian led the crowd to start laying landmines immediately. The method used was still directly frozen on the road. A row of four mines used a trip rope and was directly tied to the trees on both sides.Of course, not only on the roads, but also in the mountains and forests, a lot of landmines were scattered scattered, but they were all marked to ensure that our own people would not step on them by mistake.

In the end, Shi Jian deliberately erected a wooden sign in front of the first landmine, with four big red characters written on it: "Landmines are dangerous, and idlers are not allowed to enter!"
