"Boom!"

The second fuel tanker exploded at close range, both the sound and the explosion wave were more powerful than the previous one, this explosion, it was equivalent to announcing that the real test had arrived, and after the fire caused by the explosion gradually subsided, a large number of zombies stepped on the corpses of the same kind and swarmed, Xie Tian stood on the main control building, and said through the walkie-talkie: "Start filling fuel immediately." ”

Gasoline-based, kerosene and diesel supplemented by a large amount of fuel oil was filled into the ditch, the oil level in the ditch rose rapidly, until the zombie army approached the wall, Xie Tian immediately ordered the ignition, in an instant, the gas around the wall of the safety zone was raging, the flames soared up six or seven meters high, the zombies instinctively feared the flames, but the number of zombies was too much, the zombies at the front could not resist the push behind, a large number of zombies fell into the ditch, and the fuel burned out a gap that the zombies could not cross, in an instant, A strong smell of burnt paste permeated the surroundings.

The firearms were not immediately put into use, in this case, the incendiary bombs were far more effective than the guns, a large number of homemade incendiary bombs were thrown out of the wall by the survivors through the wall, countless flames exploded in the zombie group, even some evolved zombies jumped to the wall with all their strength, but they were also killed because of the dense sharp iron thorns on the wall, the jumping power of ordinary E2 itself is extremely large, coupled with the gravitational acceleration of the fall, when they stepped on the dense iron thorns, the iron thorns made it difficult for them to grasp the balance of their bodies, Some fell straight into the ditch, others were killed by heavy weapons for a momentary pause on the wall, and the spikes could even pierce the soles of the respective E2's feet, pinning their bodies to the wall.

In the first phase of the defense, everything is very favorable to the safety zone, and there is sufficient fuel reserves to ensure that the fire under the wall continues to burn, and the oil level has climbed and flooded the exit of the pipeline, so that even if the fire is raging outside, there is no danger of adding fuel from inside the wall.

Burning zombies has become the most effective way to completely kill zombies, but soon, the number of zombies will have the upper hand, after all, the ditch is only a few meters deep, a large number of zombies are pushed into the fire pit, after a while, the entire ditch is filled with zombie corpses, and the fire is gradually weakening, Xie Tian is a little worried, these zombies who died under the wall will not use their own corpses to provide a cornerstone for latecomers to climb over the wall in the most primitive way.

Xie Tian hurriedly looked at the railway bridge in the south, although there were still a large number of zombies on the opposite side of the railway bridge, but the passing ability was too poor to cause them to pose a real threat to the safety zone, the spraying of the fuel tanker continued, and now it was the second tanker, Xie Tian hurriedly said: "Lao Cheng, hand over the train to Liu Mu, and the engineer will move the gasoline pump down and change it to a single pipeline spraying, and then Lao Cheng will top the tanker to the northwest corner." ”

The north-south railway of the marshalling yard is just on the westernmost side of the power plant, and if the tanker car is pushed down to the northernmost side, it will occupy a favorable position in the northwest corner, so that the gasoline spraying can cause a wide range of damage to the zombies outside the wall, at the very least, it can buffer the situation of zombies piling up in the corner.

Xie Tian saw that the deployment had been completed, and immediately turned back and went downstairs, coming to a position where the zombies were most likely to break through first, under the wall here, the corpses of the zombies had piled up nearly a meter high, and some zombies had already climbed onto the corpses of other kinds, here, if they stretched out their hands, the top of the wall was already within reach!

Xie Tian climbed to the shooting tower inside the wall, overlooking the situation below, and secretly thought in his heart, if he shot, the corpses of the zombies would be higher and higher, and the zombies could be killed, but their corpses were beyond Xie Tian's control, if the height of the zombies' corpses continued to increase, then the zombies could easily climb over the wall through this position and pour into the safety zone.

"Increase the amount of gasoline bombs projected in this area!" Xie Tian opened his mouth and roared, and the survivors who were throwing gasoline bombs at the wall nearby gathered and began to focus on throwing them to this area, the thrown gasoline bombs can often be thrown at a distance of about five meters outside the wall, so that the speed of the zombies gathering around the wall can be eased, and then, Xie Tian began to throw grenades near the burning of the gasoline bombs, although the grenades can't really kill zombies in a large area, but they can cause a wide range of damage, especially when the grenade falls into the soles of the zombies' feet, it explodes in the dense zombie group, Zombies in a range will be incapacitated and become an obstacle to the same kind behind.

The situation here has just been eased a little, and there is also danger in other positions, Junzi ran to Xie Tian's side with a worried face, and said: "Sir, the number of zombies is too much, we kill more, and they replenish faster!" Now that the ditch has been filled with zombie corpses, it is very difficult for us to fill up the fuel, and it is difficult to fully burn, the effect is getting worse and worse, if we continue like this, I am afraid it will be difficult for us to defend the wall! ”

"Why aren't the tanker trucks in place yet?" Xie Tian asked anxiously.

"Preparing." Junko spoke, "The engineer said it would take about ten minutes to complete. ”

Xie Tian gritted his teeth, no matter how good his defense was, so many zombies were enough for him to drink a pot, and at this time, news came from the main gate: a large number of zombies crowded in front of the gate, and the gate may not be able to hold out for too long!

"Drive all the heavy trucks over, and block the gate one after another!" Xie Tian is already a little anxious at the moment, if the first layer of the wall misses, then all the personnel must retreat to the second layer of the wall, at that time, the tank truck in the marshalling yard will be lost, simply relying on the defense of firearms, it is even more difficult to support for too long, if you are really forced to the roof of the building to do the last defense, although you can temporarily get safe, but there are millions of zombies below, when will it be a head to hide on it?

The number of heavy trucks was immediately driven to the gate, one by one from the inside of the gate completely blocked, three cars in a row, a total of two rows, at this moment the zombies have been the east, north, west three sides of the wall is full, in addition to the south of the river, zombies like a bean, has been completely enclosed in the security zone, three walls such a long front, more than 600 combatants seem to be very powerless, at the same time, the northern wall came from bursts of gunfire, Xie Tian hurriedly grabbed the walkie-talkie, asked: "What is the situation in the north?" ”

"Zombies have started to climb the wall!" A soldier blurted out: "The zombie corpses below have piled up nearly three meters high, and they are gathering more and more, if we don't shoot again, the zombies will enter the city!" ”

Xie Tian scolded secretly and hurriedly said: "Du Yuewei, you immediately take people to the north and concentrate on incendiary bombs to block!" ”

Du Yuewei is also powerless at the moment, she has used all the bottles and cans she can find to make incendiary bombs, but the number is limited after all, more than a thousand survivors are now basically all distributed everywhere to throw incendiary bombs, the consumption rate of incendiary bombs is too fast, it is only less than two hours, and the number of incendiary bombs has been used up by more than half.

Xie Tian never thought that the overall migration of zombies would be calculated in millions, so far, they have killed zombies in various ways, let alone 100,000! But the reduction of 100,000 zombies has not even had any visual manifestation, and it seems as if the zombies have not decreased at all.

At this moment, a message came over the intercom: "The tanker truck has been pushed to the northwest corner, and the high-pressure oil pump is ready!" ”

Xie Tian rushed over for the first time, personally climbed on the tanker, at this moment the oil pump output port on the top of the tanker has been changed to one, the caliber has been changed to more than half, Xie Tian held the oil pipe, after opening the oil pump, a large amount of fuel began to be pumped out, sprayed more than ten meters away.

Xie Tian first poured all the zombies that could be sprayed in the northwest corner with gasoline, and then ordered Lao Cheng to drive the locomotive slowly, towing the tanker car along the west wall to the south, and asked all the personnel on the shooting tower to temporarily retreat.

The zombies on the west wall were watered back and forth several times, and then, Xie Tiancai turned off the gasoline pump and ordered the fire.

A gasoline bomb was thrown out by the partition wall, the flames instantly started from the northwest corner, and spread to the entire west outer wall at great speed, this time, the pressure on the west wall was instantly reduced, and the fire dragon burned a vacuum in the zombie group, at the same time, the defense situation in the north was even worse, the gasoline bomb has run out, although there is a lot of fuel, but there is no good way to spray fuel outside the wall, Du Yuewei tried a small gasoline pump and a refueling gun, but the pressure of this pump is too small, and it is difficult for gasoline to be sprayed too far away, Therefore, it can only be used to defend zombies next to the wall.

Xie Tian handed over the task of spraying fuel on the west wall to Li Yang, and he immediately turned back to the north wall, where boxes of grenades were stacked, and Xie Tian began to lead more than 20 soldiers to throw grenades outside the wall without stopping, and the sound of explosions was endless for a while.

Xie Tian knows that if he continues to defend like this, even if he can support it temporarily, once the consumption of grenades and ammunition is too large, he will still be attacked by zombies, after all, all their ammunition is only 200,000, even if every bullet can solve a zombie, this is insignificant to the army of millions, and the most terrible thing is that in this chaotic situation, it is impossible to guarantee that the bullet has such a high killing rate.

In the anxiety, Xie Tian thought of the Nanchang Safety Zone, so many zombies on the west side were delayed by themselves, and the Changbei Security Zone is north of the Ganjiang River, so that the west, south and north of the Changbei Security Zone will not have much pressure, and there is Poyang Lake in the east of it, damn, the geographical location of the Changbei Security Zone is really good! And they are so happy, so much pressure on the west side, all attracted by themselves!

Barton! Barton: When will you reach E2? If you reach E2, I may be able to borrow your face and go to Changbei to find support

In an instant, Xie Tian's mind flashed! I thought of the high-level zombie who was knocked off at the bridge! Barton eats E1 and E2's pituitary gland, and the effect is already very gentle, if he can get the energy of that high-level zombie, can he break through to E2 as soon as possible, and then restore his physical appearance as a human???
