Since this lunch, the safe zone has entered a state of super high intensity operation. Everyone is doing their best to complete their respective work. No one is lazy. At present, the zombies in Fengcheng have not yet been deployed on a large scale. Two cross-river bridges must be blocked before the zombies in Fengcheng move.

A large amount of soil dug out from the trenches came in handy at this moment. All the dump trucks used to pull coal were sent out. After a trip, they pulled the full amount of soil to the south of the two bridges, and then used manual and machinery to accumulate a 5-meter-high earth wall. The biggest purpose of this earth wall was to make the zombies ignore the bridge that can cross the north of the river and guide them to the east and west sides. However, in order to prevent accidents, Ma Jicheng chose the most suitable blasting point, installed a large amount of mine explosives, and then used cables to cut the blasting line to connect it. The blasting line was buried in the soil on the river bank to avoid any accidents.

In this way, the zombies in Jiangbei are not afraid. If they really can't do it, Xie Tian can blow up the two bridges and then defend the railway bridge with all his might. The railway bridge is not wide. If the train drives up, the gaps left on both sides can only be passed by one person. When the train is driven up, no matter how many zombies there are, they will be intercepted immediately.

All work has been arranged, and in order to obtain more fuel as defensive materials, Xie Tian took Zhao Ziye and a dozen soldiers and drove with Lao Cheng to the locomotive. As soon as the train started, Lao Cheng said: "We won't go west this time, we will go east. The road to the west has been cleared to the grain warehouse, and no sign of the oil tanker was found."

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

After the train drove to the "people" bifurcation point, the switch was closed, and everyone ran to the cab on the other end of the train and began to drive eastward. They were about to enter Fengcheng Railway Station to the east. I wonder if I could gain something there.

According to Lao Cheng, oil tankers on railways are very common. Basically, most of the fuel transportation in the country is carried out by railways. A large amount of fuel is transported to large oil depots in various places through railways, and then distributed by oil depots by steam. Therefore, it is not difficult to find oil tankers on railways.

When the train was about to approach Fengcheng, we encountered a special shipping truck here. Lao Cheng asked Xie Tian if he wanted to push the truck from the fork into other roads. Xie Tian hesitated for a moment and said, "Pull it back. The shipping truck should be full of express delivery and railway logistics items. There must be a variety of things. Maybe there will be a lot of things we can use."

Lao Cheng nodded, pointed to the locomotive facing him and said, "This internal diesel locomotive is DF11g. The two sets of locomotives that are fixed and reconnected are much better than ours. It's better to drag it back."

As he said that, Lao Cheng controlled the train to approach slowly. After hanging up the chartered train, he immediately drove in the opposite direction. He first sent the chartered train back to the marshalling station in the power plant, and then set off. This time he drove directly into Fengcheng Railway Station. After passing through Fengcheng Station, he drove about twenty kilometers and cleared two passenger trains and a coal train, he finally encountered an oil train. Then, thousands of tons of fuel were dragged back. This time, as long as a large number of zombies approached the safety area, Xie Tian would set off an earth-shaking fire.

When the trailer tanker returned to the power plant, Lao Cheng opened another rail for marshalling and stopped all the oil columns in. Then Xie Tian got off the car and carefully inspected the entire tanker truck. The marshalling of the seventy-three tanker trucks was marshalling. Each section was nominally 60 tons, basically halfway between gasoline and diesel, and more than 4,000 tons of fuel were in place. Xie Tian felt a little relieved.

Eric, who had been in charge of surveillance on the roof, saw a large number of tankers entering the marshalling yard and immediately found Xie Tian and said, "Xie Tian, ​​can you find a way to store these fuel in large containers and place them in the main traffic lane? In this way, once a large number of zombies approach, I can use a sniper rifle to detonate the fuel first and create a fire in the zombie group."

Xie Tianxin said, why didn't I think of such a good method? Eric's gunshot technique is as magical. Now the west and east are both land, and he has no way to stop a large number of zombies from these two directions. However, if Eric's method is followed, a container of a large amount of fuel was placed along the way, then his bullet could trigger a powerful explosion and fire. This method of mass killing is extremely powerful!

What kind of object should I use to store oil? Xie Tian thought about it and decided to use all the oil tank cars I found before, but there was no equipment for large-scale oil pumping. The engineer immediately volunteered and said, "Sir, send me some helpers and a truck. I will go to a nearby gas station to remove their oil pump!"

"Okay!" Xie Tian said, "You will take people there now. You can decide who you need to help. Go and go back quickly!"

The engineer nodded and said, "The nearest gas station is only one kilometer away from here and can be handled soon."

"There are several large oil barrels in the canteen that used to hold soybean oil." Xie Tian suddenly thought of the situation when he cleaned the canteen before, and blurted out to a soldier beside him, "Take a few people and bring all the large oil barrels here."

The army only has guns, and the best weapon of mass destruction is the grenade. However, grenades are good at dealing with humans, but dealing with zombies is very ordinary. All the core of zombies is in the brain. If the brain is not destroyed, even if the zombies are blown away with one hand or the intestines are blown out, it will not have any effect. Gasoline is different. The high heat of gasoline when burning will cause the zombie brain to die immediately. It is an excellent way to deal with zombies. No wonder even the army has to use napalm bombs to bomb key cities. After the bombing, all the zombies are left with burnt bones, which will turn into ashes when the wind blows.

Soon, the Engineer's Army removed several oil pumps of all sizes from the gas station outside the city. The large oil pump was the main oil pump of the gas station, and the small one was the oil pump attached to the gas tanker. Xie Tianming man set up a high iron frame, which was horizontally above the oil tanker truck, and then mounted the large oil pump on it, connected it with a special oil pipeline and connected it to the power supply. After the Engineer's Army released static electricity for the body of the oil tanker truck, he immediately began to fill several oil tankers and the tanker truck was immediately driven out. Xie Tian and Eric stood on the roof of the main control building, and directed the oil tanker driver to park the tanker truck in a suitable position through the intercom.

"The problem on the east side is not very big, because there is a Changbei Security Zone blocking us." Xie Tian said: "The focus should be on the west side, the smallest oil tanker and several oil barrels are placed in the east, and the rest are placed in the west."

Eric nodded and said, "The nearest northwest corner of the safety zone should be more than 500 meters, and the farthest can be placed at a position of 1,500 meters. In this way, the farthest one will detonate first and will not affect the nearest one."

Xie Tian agreed to Eric's opinion. After the commander parked the vehicle in place, his first preparation was completed. The power of this vehicle's explosion could cover at least a range of nearly a kilometers, and a large amount of fuel would last for a long time. There were two such oil tankers, and several large oil barrels were scattered at other places. This would be enough to cause great casualties to the zombie group coming from the west and gain a lot of precious time.

As for the car that was brought back from the car before, Xie Tian had no time to check it out. Think about it, it should be full of all kinds of things sent by consumers, especially online shopping, and the supplies here should be the most complex and complete. But the main task now is to do a good job in defense in the safe area. How many surprises are there? Let's keep them and then slowly investigate them later.

Du Yuewei led a group of women to gather all the glass bottles first. When they found that the number was not enough, they mobilized people to look for the hot pot in the dormitory building, but everyone was very involved and all the containers they could use were collected.

After the engineers linked a small oil pump, they handed the oil pump to Du Yuewei. It was very easy to use. The switch on the fuel gun was the switch of the oil pump. Gasoline would be drawn out as soon as it was pressed. Du Yuewei ordered people to find a bed sheet and cover it, and then soak it in water to spread it on the ground to prevent static electricity from posing a danger to these gasoline containers. After filling a pile, they immediately covered it with a wet cloth to ensure safety.

Xie Xiaofei's work was a bit difficult. He had to weld and install pulley frames on the roof of each building, and he had to be able to bear a load of 100 kilograms on the basis of self-weight. He and several welders had limited technical strength and worked hard for a whole afternoon before he could barely get one.

This made Xie Xiaofei cry almost cry. Other people's work was almost done. Only when his own work was progressing slowly, and he gritted his teeth and worked hard to do it. It was only at this speed. After all, they only had some simple equipment, and they were working on the rooftop, which was difficult and time consumption.

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

Xie Tian asked the reason and comforted him: "It's okay, understand the difficulties you are facing, and you don't have to worry. It's not useless to improve our safe zone for so long. No matter how many zombies there are, I believe our exterior 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 still have enough time to complete it, and others will buy you time."

Xie Xiaofei felt relieved and did not dare to delay. He hurriedly started to make the second pulley frame. The pulley was made of pulleys on the coal belt conveyor. Xie Xiaofei was smart and knew how to find the most suitable materials. After the first pulley frame was completed, Song Hui took people to transport the tents and placed ten tents on the roof of the general control building, one of which was used to pile various supplies, and the others could be occupied.
Chapter completed!
