Since this lunch, the security zone has instantly entered a state of ultra-high-intensity operation, everyone is doing their best to complete their work, no one is lazy, at present, the zombies in Fengcheng have not yet moved on a large scale, and the zombies in Fengcheng must be blocked before the zombies in Fengcheng move.

A large amount of soil dug out of the trench came in handy at this moment, and the dump trucks that were used to pull coal were all sent out, one trip after another, pulling the full soil to the south of the two bridges, and then using manual and mechanical work together to pile up a 5-meter-high earth wall, the biggest purpose of this earth wall is to let the zombies directly ignore the bridge that can cross the river to the north, and to the east and west sides, but in order to prevent accidents, Ma Jicheng selected the most suitable blasting point and installed a large number of mine explosives, The blasting wires were then cut with cables and connected, and he buried them in the dirt on the embankment to avoid any accidents.

In this way, the zombies in Jiangbei are not afraid, it really can't be done, thank you Tian can blow up the two bridges, and then defend the railway bridge with all your might, the railway bridge is not wide, if the train goes up, the gap left on both sides can only be used for one person to pass, and when the time comes, the train will be driven up, and no matter how many zombies there are, they will be immediately intercepted.

After arranging all the work, in order to get more adequate fuel as defense materials, Xie Tian took Zhao Ziye and more than a dozen soldiers, together with Lao Cheng, only drove the locomotive to set off, and as soon as the train started, Lao Cheng said: "Let's not go west this time, go east, the road to the west has been dredged to the grain depot, and no shadow of the tanker truck has been found." ”

Xie Tian nodded and said, "Then go east." ”

After the train drove to the "human" zigzag fork point, the turnout was closed, and everyone ran to the cab at the other end of the train, and began to drive in the opposite direction to the east, heading east to enter the Fengcheng Railway Station, I don't know if there can be something to gain there.

According to Lao Cheng's words, the oil tank car on the railway is very common, basically most of the fuel transportation in the country is carried out by railway, through the railway will be transported a large amount of fuel to the large oil depots in various places, and then by the oil depot, in the way of automobile dispersion, so it is not difficult to find a tank car on the railway.

When the train was about to approach Fengcheng, he met a special transport car here, Lao Cheng asked Xie Tian if he wanted to push the car from the fork into other roads, Xie Tian hesitated for a moment, and said: "Pull it back, the chartered car should be full of express and railway logistics items, it must be a variety of things, and there are a lot of things that we can use." ”

Lao Cheng nodded, pointed to the oncoming locomotive and said: "This diesel locomotive is DF11G, and the two groups of locomotives that are fixed and reconnected are much stronger than ours, and it is good to drag them back." ”

Speaking, Lao Cheng controlled the train to approach slowly, and immediately reversed after hanging up the chartered car, first sent the chartered car back to the marshalling station in the power plant, and then set off again, this time directly into Fengcheng Railway Station, after passing through Fengcheng Station, traveled about 20 kilometers, cleaned up two passenger trains and a special coal train, and finally encountered an oil train, and then, thousands of tons of fuel were dragged back, this time, as long as a large number of zombies approached the safe zone, thank God to put an earth-shattering fire.

The trailer tanker returned to the power plant, Lao Cheng opened another railroad track for marshalling, and stopped all the oil trains in it, and then Xie Tian got off the car to carefully inspect the entire train of fuel tankers, the marshalling of seventy-three tank trucks, each nominal is 60 tons, basically gasoline and diesel are half open, more than 4,000 tons of fuel are in place, Xie Tian is also a little relieved in his heart.

Eric, who had been monitoring the rooftop, saw a large number of fuel tankers entering the marshalling yard, and immediately approached Xie Tian and said, "Thank God, can you find a way to store this fuel in a large container and place it in a traffic artery?" This way, if a large number of zombies approach, I can use a sniper rifle to detonate the fuel first and create a fire in the zombie horde. ”

Thank you Tianxin said how I didn't think of such a good method, Eric's marksmanship is like a god, now the west and east are land routes, and there is no way to stop a large number of zombies from approaching from these two directions, but if according to Eric's method, a large amount of fuel containers are placed along the way, then one of his bullets can cause a powerful explosion and fire, this way of mass destruction, is extremely powerful!

What kind of object is used to store the oil? Xie Tian thought about it and decided to use all the several fuel tank trucks he found before, but he lacked the equipment for large-scale oil pumping, and the engineer immediately volunteered and said: "Sir, send me a few helpers and a truck, and I'll go to a nearby gas station to remove their fuel pumps!" ”

"Good!" Xie Tian said: "You can take someone now, you decide who you need help with, go and come back quickly!" ”

The engineer nodded and said, "The nearest gas station is only a kilometer away from here, and it will be done quickly." ”

"There are also several large oil drums in the canteen that used to hold soybean oil." Xie Tian suddenly thought of the situation when he cleaned up the canteen before, and blurted out to a soldier next to him: "You take a few people and move all the large oil drums." ”

The army only has firearms, and the best weapon of mass destruction is grenades, but grenades are good for dealing with humans, but they are very general for dealing with zombies, all the core of zombies is in the brain, if the brain is not destroyed, even if the zombies are blown up a hand or the intestines are blown out, it will not have any effect, and gasoline is different, the high heat of gasoline burning will make the brain of the zombie die immediately, dealing with zombies, it can be described as an excellent way, no wonder even the army has to use napalm to bomb key cities, after bombingAll that remains of the zombie is a piece of burnt bones, which turns to ashes when the wind blows.

Soon, the engineer dismantled several oil pumps from the gas station outside the city, the large oil pump is the total oil pump of the gas station, and the small one is the oil pump attached to the fuel dispenser, through the walkie-talkie, command the tanker driver to park the tanker truck in a suitable position.

"The problem in the east is not very big, because there is still the Changbei Security Zone for us to block." Xie Tian said: "The focus should be on the west, the smallest tanker and a few oil drums, placed in the east, and the rest are all placed in the west." ”

Eric nodded and said, "The nearest distance from the northwest corner of the safety zone should be more than five hundred meters, and the farthest one can be placed at a position of fifteen hundred meters, so that the farthest one will detonate first, and it will not affect the nearest one." ”

Xie Tian agreed with Eric's opinion, after the commander parked the vehicle in place, his first preparations for the arrival had been completed, the power of the explosion of this car could at least cover a radius of nearly a kilometer, and a large amount of fuel would continue to burn for a long time, there were two such tanker trucks, and several large oil drums were scattered in other places, which was enough to cause great casualties to the zombie group from the west, and to gain a lot of precious time.

As for the special car that was pulled back before, Xie Tian has no time to check, think about it, it should be all kinds of things mailed by consumers, especially the most things purchased online, and the materials in it should be the most complex and complete, but now the main task is to do a good job in the defense of the security zone.

Du Yuewei led a group of women, first put together all the glass bottles, and found that the number was not enough, so she mobilized people to look for the thermos in the dormitory building, but everyone was very cooperative, and all the containers that could be used were collected.

After the engineer linked a small oil pump, he handed over the oil pump to Du Yuewei, and the use was very simple, the switch on the gas gun was the switch of the oil pump, as long as the gasoline would be pumped out by pressing it, Du Yuewei ordered someone to find a bed sheet and cover, and then soaked it with water and spread it on the ground to prevent static electricity from bringing danger to these gasoline containers.

Xie Xiaofei's work is a little difficult, to weld and install the pulley frame on the roof of each building, and on the basis of bearing the weight of 100 kilograms, he and several welders have limited technical strength, busy all afternoon to barely get one.

This made Xie Xiaofei almost cry out in a hurry, other people's work is almost done, only their own work is progressing slowly, gritting their teeth and working hard, it can only be this speed, after all, they only have some simple equipment, plus it is working on the roof, which is difficult and time-consuming.

When he was about to make the second one, Xie Xiaofei saw Xie Tian downstairs and said ashamedly: "Brother Xie, I don't think I can complete the task."

Xie Tian asked the reason, and said comfortingly: "It's okay, understand the difficulties you are facing, and you don't have to worry, our safety zone has been perfected for so long, it is not useless, even if there are more zombies, I believe that our outer wall can still be defended for a while, not to mention that the zombies have not arrived yet, even if the zombies have arrived now, you have enough time to complete, and others will buy you time." ”

Xie Xiaofei then put his mind at ease, did not dare to delay, and hurriedly began to make the second pulley frame, the pulley is used on the coal conveyor in the coal yard, Xie Xiaofei is smart, knows how to find the most suitable materials, after the first pulley frame was completed, Song Hui led people to transport the tent up, on the top of the general control building, ten tents were spent, one of which was used to stack various materials, and the others could live in people.

When they were hanging materials upstairs, Xie Tian personally went to the top of the general control building to take a look, there is only one staircase leading to the top of the building, when the time comes, if the staircase is completely blocked, even if the zombies are stronger, they will not be able to come up at all, people are absolutely safe on this, and there are a large number of materials stored here, even if people live grievance points, but they can also ensure long-term survival, this is the last move, Xie Tian prayed faintly in his heart, he worked hard to establish multiple lines of defense, Don't force yourself to use this last resort.
