The bus relied on the speed and habit formed in the early stage to continue to rush forward, and along the way, with the rotation of the wheels, one zombie after another was crushed into meat by the wheels. In the blink of an eye, more than 100 meters was left behind the bus, and the bus finally stopped under the dense siege of zombies.

The number of 30,000 zombies is indeed a lot, and in the open land to the west of the base, it can definitely be expressed as a connecting heaven and earth, but when they use the data to show it, it can also be said that in a crowded state, two zombies occupy one square meter, and 30,000 are more than 15,000 square meters, and if 15,000 square meters are calculated, it is a region of 150 meters by 100 meters. If you calculate according to the 120 people of a company of the guards, the final result is that one person only needs to kill more than 200 zombies to wipe out all the zombies.

If, the data of all this is combined with the defensive forces on the other side of the line; Plus the sniper power on the buildings on the inside of the defensive line; Coupled with the number of grenades eliminated, then after nearly 30,000 zombies are shared, in fact, the number of zombies on everyone's head is not very large, and it is only ten bullets with magazines!

Of course, all this is just a data calculation, not the actual situation!

Three buses plunged into the crowd of zombies, and they were lined up like an awl at the moment. The ten military trucks behind them were lined up in a long line, one next to the other, only about a meter away from each other, almost close to the bus in front of them. All of this was Shen Yan's advice to the guards before.

"Kill!" The bus stopped, Shen Yan shouted, and directly got into the roof of the bus through the vent in the center of the bus, and the ten soldiers in the car were called back to their senses by his roar, and they all picked up the assault rifles in their hands and began to shoot wildly through the window. Now that they have rushed into the corpses, fear is irrelevant, if you want to live, you must fight!

When the battle of the buses on Shen Yan's side was launched, the two buses and ten military trucks behind him also launched an attack at this moment. If someone watches from a high altitude at this moment, they will find that a total of thirteen cars are lined up in a long line, and the three buses are like dragon heads, and the entire car formation is a long thorn inserted into the corpse group, dividing the entire corpse group into two pieces from the middle.

"Crunch! Crunch! ”

The zombie's nails scratched the body of the car, and the sharp and piercing sound stimulated the scalp of the person to numb, but the protective net outside the car was stunned and the zombies were helpless to scratch their nails. Especially the lines of fire on the car, so that those zombies can't organize an effective attack at all. The zombies on both sides of the car who could get close to the car kept pushing the car body, and under their pushing, each car began to sway from side to side, and it seemed that the posture would tip over at any moment.

In order to prevent the vehicle from overturning, the soldiers in the car frantically shot the nearby zombies, and the zombies around the body kept falling to the ground, and the corpses were quickly built up, covering the wheels in a blink of an eye.

If the zombies have wisdom, they can completely overturn the car when the car array rushes into the corpse group, but unfortunately they don't have wisdom, all their actions are based on instinct, and their number is too much, many zombies on both sides want to attack the car body, so that the body of the car is as stable as Mount Tai under the wrestling of the zombies on both sides, and they will not jump, and they can only stare dryly in the face of the tall body. has such an effect, which is precisely because the entry point chosen by Shen Yan at the beginning is accurate enough. Of course, the decompression of the shooting of the soldiers in the car is also the key.

"Commander Li, the zombies on the south side will be handed over to you! Just kill, you're welcome! In the communicator, Shen Yan sent a message to Li Mingyu.

"Understood, be careful!" Li Mingyu responded in a deep voice.

When the convoy rushed into the corpse group and relied on the body of the car to attack, Li Mingyu had a general understanding of Shen Yan's tactics. This is clearly a tactic of dividing and encircling and destroying one by one. The convoy uses the vehicle body to form a wall-like existence to establish a line of defense, which divides the zombies that originally accumulated outside the base defense line into two, while reducing the pressure on the defense line, it also attracts most of the attention of the zombies, which makes it easier and more effective for the soldiers in the base defense line to shoot zombies.

On the side of the convoy, because the zombies on both sides have to attack it, the wrestling between the two sides makes the whole car as stable as Mount Tai, not afraid of the danger of overturning, especially the corpses that continue to accumulate on both sides of the car body, which not only increases the difficulty of the zombies pushing the car body, but also strengthens the stability of the car body! At this time, the people in the car will shoot the zombies in an orderly manner with the help of a solid body defense line, causing even more chaos to the corpse group.

The tactical method of operation is quite simple, but such a simple method of operation makes people's scalp tingle when they think about it. After all, it is something that can only be done by a madman who has gone deep into the tens of thousands of zombies.

"Try to shoot zombies five meters away!" When the zombie corpses around the car body accumulated to a certain extent, Shen Yan, who was standing on the roof of the car, shouted to the soldiers in the car while shooting the zombies.

Although more than 30,000 zombies gathered together, there was also a sparse difference in distribution. The most stressed of the entire convoy were the three buses, which were completely surrounded by corpses at the moment. According to Shen Yan's order, the main task of the military trucks in the back is to shoot the zombies around the military cards in front of them to reduce the pressure.

"All on the roof and throw grenades!" Seeing that the corpses of the zombies were already two-thirds of the height of the bus, Shen Yan hurriedly called the soldiers in the car to get on the roof of the car and move backwards.

In less than five minutes, a large number of bullets were poured in exchange for a considerable number of results, and thousands of zombies were killed, especially on the east side of the convoy against the base defense line, with the cooperation of the defending soldiers, the formation of the zombie group was no longer as dense as before.

"Boom! Rumble! Rumble! ”

Under Shen Yan's order, the ten soldiers on the roof of the car threw grenades on both sides, and the zombie corpses that had just been built not far away quickly dispersed under the cleaning of the grenades, and even the surrounding zombies were also blown up. The hull shook in the explosion, but it remained as steady, and the grenade threw continued twice before the second round of shooting began.

Ten minutes later, the soldiers on the roof of the car began to throw a second round of grenades, and after this throwing, they began to retreat to the two buses in the rear. At this time, the soldiers in the bus no longer returned to the car, but stood directly on the roof of the car and shot the zombies. This method is completely a variant version of the stabbing and pumping method when Shen Yan and Guan Feng were in the village.

After another ten minutes, the people and horses gathered on the two buses began to move again, and they went up through the back of the bus to the front of the military truck behind, and finally withdrew into the carriage, and then continued to shoot the zombies. The soldiers in the military truck began to move backwards in batches before, with a car gang with a raised outer perimeter, and they didn't worry about the zombies climbing up at all.

After experiencing the fear at the beginning, after discovering that the zombies around them were not as terrible as they imagined, the soldiers of the guard company gradually stabilized their minds, and became orderly when they transferred to the rear military card, especially when they stood on the car and shot zombies, they were no longer as crazy as before, but purposefully shot to reduce the burden on the car body, and the speed of shooting zombies was getting faster and faster!

Just transfer all the way and kill all the way, and every time the corpses of zombies accumulate to a certain extent, they will be cleaned up with grenades. The zombies who were blocked under the car, facing the prey that seemed to be within reach of the car, could only stretch out their hands and grin dryly, and every time they gathered in front of the car, they would be frantically suppressed by the soldiers on the car.

The tactics of using the car formation to fight seem simple, but in fact, it is necessary to save time and assess the situation, especially to keep the zombie corpses at both ends of the car body too high at all times, and to maintain a stable surname under its pushing. And all the soldiers in the car formation must be brave enough.

The guards had already taken a platoon of soldiers to the ground after clearing the surrounding zombies, and established a defensive line ten meters behind the last military truck. The vehicles in the entire convoy were all loaded with weapons and ammunition except for people, and there were more vehicles from front to back, especially the last two vehicles were loaded with the most weapons and ammunition, which was enough for the soldiers of the entire company to complete a reload.

As the time prolonged, the soldiers in front of the convoy continued to move backwards through the front of the car and the carriage, and Shen Yan and the people came to the last military truck in a blink of an eye, and at this time, the company led by the guard army had all gone down to the ground.

"Retreat!" Shen Yan jumped off the military card and immediately gave the retreat order to the guards.

A full hour passed, and the zombies on the east side of the car array had been killed and wounded, and the zombies on the west side had also become sparse, and the number was less than 10,000. When Shen Yan and the others went down to the ground, most of the zombies on the west side surrounded them, and only a few of them bypassed the car formation and rushed to the base defense line.

A large number of corpses were piled up on the ground, more than a meter thick, because of the cleaning of grenades, most of these zombie corpses were in an incomplete form, and if someone carefully examined these corpses, they would find that almost more than seventy percent of the broken corpses seemed to have undergone weathering, and they were extremely dry.

After this hour of killing, about two-thirds of the more than 30,000 zombies were wiped out. After reorganizing the manpower, Shen Yan led the guard company and began to turn to the west side of the car formation to clean up the remaining zombies, and the tactics he used at this moment were the "fishing tactics".

The hour-long killing made the soldiers of the guard company a little tired, and although the guns in their hands were renewed, the speed of action was obviously not as good as before. Shen Yan didn't urge them, anyway, the zombies were moving slowly, they just needed to destroy them steadily and gradually on the move. On the side of the defense line, the soldiers who came later also began to enter the battlefield at Shen Yan's suggestion, attacking from the southwest and entrapping Shen Yan's side.
