Apocalypse Cockroach

Beneath the wall are shunted zombies. On artificially modified ground, various traps lay out. One metre high dirt wall needs to dig up three metres deep trenches to collect dirt. A hundred metres long, three metres high wall needs two hundred metres long, five metres deep trenches. With the help of dozens of excavators and hundreds of building machinery, ten kilometres long walls are thousands of places. The work of tens of thousands of people makes this place a more complex labyrinth than a hot spring base. Without arrows of all colors on the wall, even fighters with a wide view will get lost.

Huge trenches of all kinds are buried graves of zombies, and large and small half-height walls are signposts of shunted zombies. A mystery formation will shunt zombies entering the position, entering a huge pit from the channels on both sides of the position, a kilometre in the face of the pit, where the soil has long been removed, up to five meters deep, all four walls are dirt walls, and steep dirt walls can only be climbed out of more than S3-type zombies.

The two pits prepared a feast for the shunted zombies. Zhang Xiaoqiang made thousands of flasks with a ton of gasoline for the zombies in the two pits.

Of course, not all the carcasses will be encircled in the pit, and the carcasses will have a sense of direction, and once the Z2 carcass in the sea feels wrong, attention will be diverted, saying that there will have to be other tensions.

After the forward position, there was a giant square square of three or four square kilometres in the centre of the wall, stacked thousands of one-person pyramids of gravel in the open space of the square, with cables buried underground beneath each pyramid, and thousands of cables clustered together, eventually by a cable, connected to a group of electronic starters.

Using so much energy and material, these rubble pyramids are naturally not used for decoration. Zhang Xiaoqiang, in the gathering place, finally found a guy who can make explosives. Among the soldiers of the Yinchuan Army and the Border Guard, such people can make explosives, especially Han Yue from the special forces and the ghost from the mercenary, even laundry powder.

Nearly a hundred tons of explosives were produced by a clandestine explosive factory set up in the rear, without anyone knowing, as one of the guarantees to support forward operations. Now, nearly half of the explosives are in these piles, each pile of gravel is buried with a variety of soil or newfound explosives, TNT, black sorghum, bitter acid, and even urea explosives with the most unsafe nitroglycerin.

Thousands of pyramids are 200,000 kilograms of explosives. Under 10 tons of explosives, Zhang Xiaoqiang can't think of anything else to survive under such force. With the exception of explosives, Zhang Xiaoqiang concentrated all his long-range heavy fire behind the position.

85mm howitzers, 130mm cannons, 122mm vintage howitzers, and 122mm 40-barrel rocket launchers, one of Zhang Xiaoqiang's households, together with a large proportion of artillery cannons that could not keep pace with the transport forces, could not guarantee ammunition supplies and could only be sealed in the warehouse in a tight manner.

In the final position, Zhang Xiaoqiang also set up an out-of-home plan just in case. All the walls in the rear are buried with countless scrap metals. There are countless explosives in the middle of these scrap metals. Once the front really fails, Zhang Xiaoqiang will detonate all the second half of the position, which is more than a dozen tons of explosives. Of course, in the interests of safety, he will not be able to use it until the last step, because accidentally, the troops of all four regiments will go up in an instant.

The troops on both sides unfolded. The soldiers of the garrison regiment, led by their respective company commanders, took forward positions along a half-empty bamboo bridge plank to fight the zombies. Don't worry about the zombies hitting them remotely, so the soldiers did not build defenses on the wall position, covering the front of the wall with a maximum of meshes to prevent S2 zombies from jumping from underneath.

The corpse sea in front of him was slowly moving forward. Zhang Xiaoqiang was also on the first line. Without a meow by his side, he held the telescope to close the forefront of the corpse sea in his eyes.

Zombie Hai Zhang Xiaoqiang did not see it twice, even the warriors around him have seen a lot of it. Apart from the new supplementary soldiers, most of the warriors behaved very calmly. Zombie is a thing that kills a lot, and they are naturally accustomed to it.

Warriors wipe their rifles, shove a bullet into a magazine, or wrap it around their waist. The front line is full of weird pre-war vibes. No one talks. Warriors keep their mouths shut and do their jobs. The sound of gun fasteners becomes the main melody on the battlefield.

Zhang Xiaoqiang also had a rifle in his hand. All his work was clear. Any changes on the front were all the business of the General Staff. He only needed to deal with possible crises in the front, such as the advanced evolutionary corpse.

Zhang Xiaoqiang cleaned up the D2 zombie herd with a heavy machine gun, just beside him, a powerful type 75 14.5 mm single-barrel heavy machine gun is his killer today, the type 75 anti-aircraft machine gun is about 4 meters long, the bottom is supported by a tripod, and the machine gunner sits on the tripod to adjust the direction of the shooting at the gunpoint.

The 1,000-meter flat distance is the theoretical distance affected by the horizon. In the case of Chang Xiaoqiang with ultra-high vision, at least 1,500-meter arc hit rate can be guaranteed. Eighty rounds of drums is a defect. Under the operation of trained professional soldiers, the replacement time can be shortened to the replacement time of the ammunition chain of ordinary heavy machine guns.

This anti-aircraft machine gun was designed in '81 and equipped with troops in' 83. Although it is now replaced by a large number of anti-aircraft missile systems, it still accounts for a significant proportion of the military. In the Yinchuan Army's decommissioned arsenal, Zhang Xiaoqiang found at least two hundred type 75 anti-aircraft machine guns. Had it not been for the small quantity of 14.5 mm ammunition, it would not have been replenished. Zhang Xiaoqiang was reluctant to equip all of these relatively light anti-aircraft machine guns to the army.

To date, only half of these anti-aircraft machine guns have been equipped with troops, 20 each in the main force, 10 in each of the three guard regiments, 15 in the Blood Wolf Brigade, five in the Blood Warrior Regiment and the remaining 10 in the two hills of the Helan Valley.

Almost all units use the same method to convert a pickup truck into a vehicle-mounted anti-aircraft machine gun, a machine gun crew of four, a driver, a co-pilot, a machine gunner, and a sub-machine gunner. The unusually flexible use of anti-aircraft machine guns in vehicles, coupled with the fact that the vehicle itself carries heavy ammunition, makes the Model 75 14.5 mm heavy machine gun popular in the military and the most trusted support firepower in addition to armoured vehicles.

Zhang Xiaoqiang touched the new anti-rust paint on the cold gun and turned his head towards the wall position behind him, surrounded by hundreds of walls, staggered several kilometres wide along the line, surrounded by a platoon of soldiers guarded on each wall of up to fifty or sixty meters long, at least hundreds of walls on the first line, although not every wall had thirty-six soldiers, the guard's two teams of teachers walked all three thousand people on each wall of the line.

The soldiers of the Guard Corps are ready on the first line, while the Majority Corps is on the second line of ammunition and materiel points. They will be responsible for transporting ammunition to the front line, collecting shells and… transporting bodies.

As far as long-range fire is concerned, all walks are on the third line, at an absolutely safe distance of three kilometres from the front line, and shells can be fired at any point several kilometres away at any time, depending on the needs of the front line.

Warriors on the fence are ready, smoking, and those who don't smoke lit special wartime cigarettes, not many, only three cigarettes per person, their daily supply, the pressure from the infinite sea of corpses does not reflect on their faces, directly into their hearts, so they urgently need something to relax themselves.

The two flanking forces have disappeared in the distance, and they will have to bypass for dozens of kilometres and start attacking on both sides of the Zombie Sea, all of which, of course, will follow the sound of the main position.
