The ice wall designed by the General Staff is not a solid line, but a dotted line, the ice wall that needs to be built on the 38th parallel is more than 200 kilometers is enough, there is a gap every other distance, the gap is in the shape of a trumpet, the bottom of the horn is in the south, and the wide exit is in the north, it is better to put the zombies in to fight, it can reduce the frontal pressure, and it can also slow down the impact of the zombies, the more crowded it is, the slower the action.

The sniper of the troops is carried out from north to south, at the bottom of the horn, and the position is wide enough to lay more heavy fire points.

This design greatly reduces Sun Xiaoshan's workload and saves water.

In winter, many streams and rivers were frozen to the bottom, so they built several huge earth pits from east to west on the north side of the 38th parallel, and the soil pits were surrounded by dense aqueducts, and at the end of the aqueducts was a field stove used to melt ice and snow, and after the water flowed into the earthen pits, it was poured on the 38th parallel by a pump.

The General Staff Headquarters also sent engineering units to carry out a 300-kilometer-long northward directional blasting on the south side of the 38th Parallel.

The defensive firepower points north of the 38th parallel are moving to the north side of the 38th parallel, and it is expected that the zombie group will only need 2~3 days to hit the 38th parallel, and the Ministry of Industry will need at least 4 and a half days, and they will hold on for 2~3 days to ensure that the ice and soil defense wall is completed.

At the time of the reconquest of Pyongyang and Seoul, a detailed industrial information on the DPRK and the ROK was sent to Sun Xiaoshan, who sent the materials to various departments for study and mastery according to various industrial categories.

After summarizing the plans of various departments, Sun Xiaoshan began the overall dispatch according to Li Fengyi's authorization.

He sent power personnel to first integrate the power personnel at the UNSCOM power plant and the survivors in North and South Korea, and they wanted to make sure that the pumping machines that made the ice wall had electricity.

The largest number of personnel were dispatched deep into the DPRK and the ROK to collect pumping machines and diversion pipes within the control of the Special Commission, and at the same time, the pumping machines and diversion pipes from the special commission's material warehouse were also urgently transported to the front line, and the total number of pumping machines was mobilized according to the density of 20 meters per pump, and a total of no less than 12,500 pumping machines were mobilized, and another 5,000 spare ones were to be prepared in the rear, and then they were shipped.

Many of these personnel who collected pumping machines and water pipes in North and South Korea were soldiers who happened to be resting nearby, saving a lot of time on the road.

For a time, the area of the Special Commission was full of soldiers in plate armor carrying all kinds of supplies, they braved the wind and snow and fought regardless of fatigue, all means of transportation were mobilized, everything had to ensure the needs of front-line pumping machines, weapons and munitions, and even pedaling bicycles to transport supplies.

A series of loud noises continued to sound on the south side of the 38th parallel, collapsing up the earth, accurately falling on the 38th parallel, piling up an earthen wall 20 meters wide and 10 meters high, forming a deep trench at the explosion point, and the sappers were very skilled in directional blasting operations.

For this blasting, all the explosives in the hands of the special committee were concentrated, regardless of cost, regardless of loss, and even a lot of shells from the 50s were filled into it and detonated, unlike the very accurate directional blasting that is required to be controlled in the downtown area, these shells are very suitable for demand, and the performance is hot, even if it is a dud, it doesn't matter, the worst result is that the zombies are trampled on by them when they rush over, and they will not hurt humans anyway.

The fire was lit one by one, and the melted ice and snow were steaming down the diversion canal into the huge earthen pit, which was immediately pumped out by the water pump and poured on the earthen wall.

By the time the first pumping machine was activated, the rumbling of sniper units could already be heard in the distance.

From time to time, there are a line of light infantry, heavy machine gunners, and artillerymen who sit on heavy trucks and withdraw along the preset passage, and they stretch out their heads from the carriage to look at the wonders of thousands of water dragons spitting water on the 300-kilometer-long 38th line, looking at the ice wall that is getting higher and higher, and getting longer and longer, and feeling that their confidence has been restored.

The effect and speed of pouring the ice wall greatly exceeded Li Fengyi's expectations, he originally thought that a 5-meter-high and 3-meter-wide ice wall was enough for Sun Xiaoshan to use his strength to eat, who would have thought that everyone would have high firepower to pick up materials, and a group of people would think about how to make trouble for zombies, and they would do it so ideally. ,

About half a day after the pouring operation began, the 155 heavy artillery on the north side of the 38th parallel began to roar, and the zombie group had already entered their firepower.

After the 38th parallel was designated as the decisive battle line, all the heavy artillery from the north was mobilized, and in consideration of the prevention and control factors, one field air defense armored vehicle would be arranged at intervals, often facing the gap, and there was a lack of missiles to look at the stealth fighters.

By the time the pouring was carried out for a day, the shadows of the zombies could already be seen from the heavy artillery bombing sites for several days, they were wearing thin spring clothes and were not afraid of the cold of North Korea, and they were as impulsive as the young men rushing to a date.

The troops on the south side of the 38th parallel withdrew even more, leaving the last line of light infantry of the Korean People's Liberation Army in the last days and the heavy machine-gun line 100 meters behind them.

The ice wall has almost been poured, Sun Xiaoshan has also come to the front line, the manpower and material work is basically over, and what needs to be done now is to concentrate on building the ice wall.

He led people to inspect along the 38th parallel, and if they found that they were not qualified, they immediately asked to return to work, and if there were passive sabotage, it was very likely, because they had just transferred the prisoner brigade in the basic labor brigade.

In this case, Sun Xiaoshan, in accordance with military law, asked the guards to execute them on the spot, cut off the heads of the prisoners, threw the corpses on the ice wall, and poured them into a wall.

Sun Xiaoshan felt that he had the style of Qin Shi Huang who built the Great Wall and piled up the city wall with the corpses of the conscripts.

As the number of retreating fighters increased, after the regrouping, the pouring crews were put into shifts, and they worked in shifts of 12 hours each.

The water of streams and small rivers is almost exhausted, considering the need for water for the defense of zombies fighting the wall, Sun Xiaoshan decided to divert the sea water to pour, and the 3 kilometers of the seaside are a paradise for mutant animals, they loom in the sea ice, and they are excited to watch the life and death games of humans and zombies.
