Chapter 128: Zombies attack (III)

The train's slaughter was not hindered at all because of the growing number of zombies. The repeated crushing made the southern half of the railway bridge a real meat grinder. Whether it was a corpse or a living zombie, as long as it was crushed by the train, its legs would be broken, and its head or the entire body would be pressed into two from the crotch. The speed of blood flowing could not even satisfy the drainage outlet, and it even had to spread to the north end.

Occasionally, there are a few evolutionary zombies that happen to jump onto the train, but there is no good ending. If they come through the locomotive, Xie Tian will let them come. But as soon as they emerge at the northern end of the railway bridge, they will be immediately beaten into sieves, and there is no chance for evolutionary zombies to face infantry chariots and excavators.

This is mainly due to the overcrowding of zombies. The zombies in front cannot pass, while the zombies behind are desperately rushing forward. Some evolutionary zombies are even squeezed in the middle and can only move forward with the zombies, but they cannot pull away at all, greatly reducing the combat effectiveness of zombies and making them become cannon fodders that have been killed one after another.

That night, the safety zone was already red in its eyes. The train was constantly starting to brake overnight. It drove in when there was almost no fuel in the middle of the journey. The personnel who had already brought the fuel to fill were ready. They opened the fuel tank and quickly filled the fuel. A locomotive filled nearly 9,000 liters of fuel. This time, it was filled until dawn.

At dawn, Lao Cheng was already exhausted. Liu Mu took advantage of Lao Cheng's drive in again and climbed up. Under Lao Cheng's professor, after learning about the way the train advances and brakes, he took over Lao Cheng's position. Lao Cheng was not relieved and followed him for an hour or two before he confirmed that Liu Mu was familiar with the road. So he sniffed in the passenger seat for a while to replenish his energy.

It was also at this time that people truly saw the scale of this zombie group, and it was not an exaggeration to describe it as boundless. However, because the defense of the railway bridge was always strong, everyone was not affected by the horrific scene on the other side.

Xie Tian stood at halfway up the chimney all night. As for his current physical condition, there was no problem at all for several days and nights. After dawn, he asked the defense personnel to change shifts to defend, and the others immediately started to rest. The west side has always been Xie Tian’s biggest concern. He must let the soldiers rest well, so that once there is any situation in the west side, everyone can join the battle as soon as possible.

After the canteen prepared breakfast, some survivors began to deliver the food to the bridgehead. After the other survivors hurriedly had dinner, they immediately devoted themselves to their work. Xie Tian asked Eric to keep an eye on the situation on the west side, came down from the chimney, and went to the bridgehead to check in person.

The number of zombies on the other side was still too large. Xie Tian looked worried and wondered whether there could be a way to improve his ability to kill. At this time, the engineer soldier said to Xie Tian: "Sir, if we can add a fuel tanker in, then fix the oil pump on the top of the tanker and spray gasoline on the zombie group, this will have a large-scale killing effect, but the problem of oil pump power is not easy to solve."

"It is easy to solve the problem of electricity. You can come with a small diesel generator, but how to control it." Xie Tian said in a little difficulty: "The tanker truck is too dangerous, and the roof cannot be welded with a protective net. We can't let the fuel spray all the way from the safety zone into the zombie group."

Immediately, Xie Tian suddenly remembered Li Yang. This kid had a high talent in electronics, or he could solve this problem.

Xie Tian hurriedly called Li Yang over with a walkie-talkie. Now he is at the gate of the city, and surveillance or not has no practical significance.

After Li Yang arrived, he heard Xie Tianyi say that he hesitated for a while and said, "This is a good solution. If there is a ready-made remote control component, it is best to be the power supply component of the remote control racing car. As long as the power supply component is installed on the power line of the oil pump, the power switch can be controlled from a distance. When the tanker truck drives into the zombie group, turn on the switch to supply power to the oil pump so that it can spray a large amount of fuel out. Then when the train retreats, you can use a sniper rifle to ignite the gasoline from a distance."

Xie Tian was happy and said, "You go to the chartered car to find it now. I don't believe that there is no remote control toy or something in the express delivery of the entire train."

Li Yang's scalp numb and he said, "Looking for a needle in a haystack...I'll try it."

The railway bridge held on for two hours again. At 10 o'clock in the morning, Eric's voice came: "Thank you, there is movement in the west!"

Xie Tian hurriedly climbed into the General Control Building, and what he was most worried about was still happening.

The entire west horizon is black and stretches for dozens of kilometers in width. As for how long it is, Xie Tian is hard to see at this moment. The distance is about thirty kilometers, but it is at most in the afternoon, and it will be there.

The zombies on the south are just a small test for the defense of the safe zone, and the west is the real test. So many zombies will be directly outside the wall, which is enough to drain the entire safety zone. Xie Tian dared not neglect and immediately ordered: "The personnel responsible for the oil pipeline immediately check the oil pipeline under each wall and the fuel reserves next to it to ensure the smooth flow of the oil storage tank. Other survivors will distribute the finished incendiary bombs to various shooting towers. Pay attention to safety during transportation projects and do not have any accidents. Yufei, distribute the grenades of the ammunition depot, and then send people to various shooting towers, so that all the ammunition will be moved to the yard and distributed automatically."

All the survivors were busy and began to distribute ammunition for each shooting tower. Xie Tian stood on the general control building and looked at the westward terrain again. There was only one highway in the west, and there were many housing and factory buildings on both sides of the road. I believe that zombies would gather in large quantities on the highway. They had already placed two tankers with 30 tons of gasoline on the westward highway, and several large oil barrels filled with gasoline. No matter how many of these zombies were, give them a pot first when they came!

The zombies in the west were still approaching, and Li Yang finally discovered that he led a few people to find a high-end model aircraft in the pile of express packages, and took off the remote control system and remote control, cut off one of the power cords of the largest gasoline pump, and then installed the remote control receiving and execution components in the middle of the power cord. After the air machine tried several times, the remote control system responded well. As long as Li Yang gave the power supply command, the execution components would immediately be together with the power supply, and the gasoline pump would operate.

As for how the gasoline pump can be sprayed to both sides of the tanker at the same time and sprayed further, the engineers came up with the idea to change the oil outlet pipes of the oil pump into two linked together, one left and one right, each of which is cut short to less than one meter long, and then hang it up with iron wire to an angle of 30 degrees, and then flatten the two final ports of the oil transport, which reduces the ability to pass by half, so that high-pressure gasoline can be sprayed to both sides of the tanker at the same time. Moreover, since the ports are flat, the spray range is larger.

While there was still time, Lao Cheng got off the train and started to use another locomotive to pick out a tanker full of gasoline in the marshalling yard, and then linked Wujiehang chartered carriages. Then, while Liu Mu drove the train back to the safe area again, Lao Cheng didn't care about rest, and immediately disassembled and woven the three carriages on the bridge deck with the train, and then drove the train himself and added the tanker truck with the generator and Wujiehang chartered carriages.

In this way, the length of the train increased by nearly a hundred meters again, and the tanker was ranked fourth to the bottom. Then, the train retreated again. This time, because the train was a little longer, the distance to exit the southern end of the railway bridge was longer. When the tanker just left the southern end of the railway bridge, Li Yang immediately controlled the oil pump to supply power through the remote control. Almost in a moment, everyone saw the oil pump on the top of the tanker spraying a large amount of fuel high, just like the feeling of garden sprinkler, but the force was much larger than that, and it sprayed nearly ten meters away. In addition, the train retreated by more than two hundred meters, and the spray range this time was very large.

When he came back, this spraying action continued again! When the tanker entered the railway bridge, the spraying stopped immediately. Then Xie Tian immediately said to Eric: "Shoot into the areas where fuel is sprayed on both sides!"

Eric is much more experienced than Xie Tian. Bullets come out of the muzzle, with extremely fast speed and the temperature when the gunpowder explodes. After the high temperature generated by friction with the wind, they shoot at all positions where they can splash out of Mars, such as stones and metals.

In an instant, a raging fire ignited ten meters away from both sides of the railway. The fire stretched out in large areas. It looked like two seas of fire. The killing effect was amazing. Most of the zombies were wearing broken clothes, and they were soaked in gasoline from head to toe. They were ignited in an instant. The zombies stained with gasoline almost turned into fire people on the spot. Moreover, because the zombies were too dense, even the zombies not stained with gasoline could not escape the spread of the fire. The temperature around them instantly rose, and many zombies were roasted to humans without encountering the fire.

Xie Tian couldn't help but praise: "Li Yang, do a good job! The wisdom of the working people is really endless. You can create such abnormal things by relying on your own DIY! Each tanker truck has 60 tons, and we have fuel, and it's burning and pressing. I want to see how many cannon fodder they have to fill in! This thing is really useful! After the zombies in the west approach, drag the tanker truck to the westernmost railway tracks, which can just cover the road on the west side!"

The raging fire began to go out after less than twenty minutes. Because the fuel was sprayed too evenly, the burning speed was very fast. However, Xie Tian did not immediately ask Li Yang to spray it for the second time. The two large zombies that were burned to death still carried sporadic Mars on them, and the other zombies have not yet been restocked yet. After the other zombies come to fill up, they will carry out a second fire attack.

The zombies on the west side were getting closer and closer, like locusts. Until the afternoon, Eric spoke in a strong tone and said, "Thank you, the zombies are almost approaching our first tanker."

"How far is it?" Xie Tian grabbed the walkie-talkie and asked.

"Visitably, it is up to two kilometers."

Xie Tian immediately ran back to the roof of the General Control Building again. Sure enough, the zombies were only three or four kilometers away from the safety area. The farthest tanker was about 1,700 meters away from the safety area. This was because Eric was afraid that no matter how far he was, Barrett's power was not enough to detonate the tanker truck, and the second tanker truck was only 700 meters away from the safety area. If this explosion occurred, the rest would depend on these people to defend desperately.

"All combat personnel are advised to be careful, Shunzi, you arrange 80% of the remaining troops to concentrate on the west wall and the north wall, and all the remaining troops to the east wall. The reserve personnel are ready and wait for dispatch at any time. All machine gunners responsible for anti-aircraft machine guns should pay attention to your bullets for evolutionary zombies that may pass through the wall. Do not fire at ordinary zombies. In addition, all personnel responsible for filling fuel for the exterior wall ditch are immediately taken to their place and be prepared at any time."

This time, it was a total combat mobilization for the whole body. The arduous defensive battle was about to begin. Xie Tian was on the roof and saw that the personnel had already begun to take their place. At this time, Eric blurted out: "The zombies have arrived at the first tanker truck!"

Xie Tian looked up and saw that the front end of the zombie army was already on par with the first tanker truck. Then, the tanker truck was quickly submerged in the zombie group. Xie Tian said, "Eric, aim at the tanker truck, I will shoot immediately after I give the order! Be sure to aim to make sure that one blow will explode! We can no longer afford to waste Barrett's bullets!"

"No problem!" Eric immediately adjusted his breathing, and the muzzle was aimed at the upper center of the side of the tank truck. If the gun was shot, the tank wall of the tank truck could not withstand any of it. The moment the bullet penetrated into the steel, it would form a spark of extremely high temperature friction with the metal, and there would be no problem with one blow.

Xie Tian was waiting for the front end of the zombie army to exceed about 400 to 500 meters of the tanker truck. In this way, the zombies clamp the tanker truck in the middle, and the explosion of the tanker truck can achieve the greatest effect. Time passed by seconds, until Xie Tian suddenly yelled: "Let's fire!"

"Bang!" Eric's quality was not at all doubtful. Almost at the moment when Xie Tian fell, bullets had already gushed out of the muzzle. In less than two seconds, it passed by in a blink of an eye. Within a bang, the waves of air caused the tent on the roof to whistle. If it weren't for the reliable installation, it would be very likely that it would be overturned.

The explosion power of the entire tanker truck was too great. A large amount of burning gasoline gushed out, and the whole car flew up, split into pieces in the air, smashing towards the zombies at various locations. In an instant, the circle with the tanker truck as the center was completely trapped in a red flame in the circle with a radius of more than 500 meters.
