Ye Fei marked a position on the model: "The opened shaft should appear in this position, the problem now is that the Aquila cannot be contacted, and I don't know the progress of the shaft drilling, but according to my estimate, the progress should not be too slow, we can only hold on to it for as long as possible, and it is possible to hold on until the shaft is opened!" ”

"Outer bone mongrels have always swarmed up, even if we fire with all our strength, we may not be able to withstand so many enemies, how can bullets be saved?" The wolf cub had a different opinion, "Besides, our current position is unobstructed, and the field of vision is quite open, but this place is not suitable for defense at all, we are such a small number of people, and there are not many bullets, if we don't rely on a favorable terrain, how can this battle be fought?" ”

"The wolf cub is rightly worried, but it's not for nothing that the battlefield is chosen in this place." Ye Fei understood that the wolf cub had expressed everyone's common concerns, and took the opportunity to explain clearly, "The direction of the shaft is nearby, establish a defensive position in this place, once the shaft is opened, we can withdraw from the core area in the shortest possible time." ”

There are narrow buildings in the core area, and there is nothing the outer skeleton can do with the soldiers for a while, but what about after the bullets are gone?

Moreover, the narrow terrain restricts the enemy and also restricts themselves, if the soldiers are scattered in different positions in the core area, after the shaft is opened, it is impossible for either Ye Fei or the four captains to regather the scattered team in a short period of time, not only can the captured people not be rescued, but even the commandos who attacked the bone mound will be lost here, and evacuating the bone mound will become a big joke.

Those present were all experienced junior officers. The truth can be imagined without Ye Fei's explanation, and after understanding the stakes, no one raised any objections.

Ye Fei sighed and said, "Threatening the enemy with black bone men should work, but we can't put all our hopes on those prisoners, we must have a complete emergency plan." ”

"What if the threat doesn't work? The existing bullets will last for a maximum of ten minutes, what if the shaft has not been opened after the bullets have been opened? The veterinarian asked worriedly.

"If the enemy attacks directly regardless of the life and death of the black bone man......" Ye Fei hesitated here and said ruthlessly, "Tell the soldiers, once the battle begins, try to use the rifle to fight, after the rifle bullets are exhausted." All of them retreated into the core area to fight street fighting. ”

Everyone was silent for Ye Fei's order. Retreating into the core area is tantamount to drinking water to quench thirst, but this is the only way to keep the troops alive.

"If only there were any of our men on board." The black bear said in disappointment.

If there is another assault team on the battleship, it can be airborne directly into the core area through the shaft. Disrupt enemy arrangements while bringing ammunition supplies to trapped troops.

"Forget it." The saber, which had not spoken, spat out the turbid breath in his chest fiercely. "I still think the shaft is thick enough. Just drive the assault ship in. ”

Ye Fei's eyes lit up.

In order to reduce the amount of work and speed up the progress, he simply chose a ready-made shaft on the bone mound to continue to deepen the bone mound.

You must know that the shafts on the surface of the bone mound are all used to house the lair of the biological warship!

The size of the small fish ship varies in size. However, the length of the adult body is generally about three kilometers, and although the body diameter is thinner than that of an assault landing ship, the small fish does not go up and down vertically in and out of the shaft like launching a nuclear bomb, but lays the hull flat and lands.

The diameter of the shaft is enough for the assault landing ship to enter and exit the bone mound, as long as the Aquila opens the shaft, Ye Fei can re-establish communication with the battleship, if the situation really reaches the point where you have to fight street battles with the outer bone people to hold on, why don't you send an assault landing ship to directly enter the core area of the bone mound?

With the armament of the assault ship, there is no pressure to pack up millions of exoskeletons, as long as the flow of exoskeletons that continue to pour into the core area is intercepted, the exoskeletons who enter the core area will immediately lose their backup, and it is not difficult for well-trained fighters to clear the limited enemies in the core area, and then the situation between the two sides will be reversed again.

After figuring out all this, Ye Fei finally found a way home for the troops in the worst situation. However, he thought about it carefully, and thought that it was better not to announce this idea first, after all, he did not know at all how thick the diameter of the shaft dug by the Aquila was, what if the soldiers were given hope, and the last assault ship could not enter?

Although the Outer Bone Man had little time left for everyone, everyone still gradually perfected all aspects of the strategy in ten minutes, and made a plan to deal with every conceivable situation, and when everyone was almost done, a group of Outer Bone Man suddenly rushed out of the passage opposite the support column, and rushed to the human position like rabies.

"Monkey!" Ye Fei hurriedly reminded.

The monkey in front of the human position waved his arm, and the six warriors guarding the Black Bone pulled the bolt at the same time, and loaded the rifle aimed at the Black Bone Man.

"Stop!" The monkey aimed at the ground in front of the black bone man's feet and fired two shots, and then the muzzle of the gun was raised and aimed at the black bone man's temple, but the momentum of the outer bone man not only did not weaken, but was three points faster.

The monkey was surprised, and subconsciously wanted to kill the chicken and make an example of the monkey.

The meaning of the words is clear to the warriors, but the key is that the outer bone people don't understand!

Moreover, some of the outer skeleton people who rushed to the front had a brief exchange of fire with the commandos led by Ye Fei, and the Zhilu Dao rifle was a very lethal sharp weapon, plus they couldn't understand what the monkey was saying, and mistakenly thought that the monkey wanted to kill the noble royal family.

"Slow!" The veterinarian, who had been following the monkey, stopped it in time and repeated the monkey's other aspects with a translation device.

The Outer Skeleton Men who rushed in front smelled the smell of stopping, but the speed of the smell spread was limited, and the Outer Skeleton Men behind them didn't know anything, and the dense formation made it impossible for them to stop, so they could only continue to rush forward.

The army of the Outer Bone Man showed no signs of retreating, and seeing that he was about to rush into the thin defense line of the commando, Ye Fei waved his hand violently: "Three teams, fire!" ”

The three brigades that were on the front of the defensive positions immediately carried out the order. More than sixty rifles fired at the same time, and Fang deliberately raised the firing height, specifically firing at the horizontal line of the height of the Outer Skeleton, so that even if he did not hit the enemy in the center line, he could still hit the Outer Skeleton in the back, so as not to waste bullets because of the continuous firing.

The outer skeleton man who rushed in front suddenly fell in a large area.

The rifle could be fired directly at the shoulder, but the Gatling was not a weapon for shoulder-to-shoulder shooting at all, but the fighters had their own way of doing it, and the machine gunner reached the right height when several empty weapon boxes were swung to the ground. It's just that Gatling's rate of fire is too fast. The nine machine gunners of the three teams had to suppress the speed of fire as much as possible, so as not to consume the bullets too quickly.

In the hundreds of years since the large-scale use of firearms, there have been countless technical improvements in thermal weapons, but they have not deviated from their origins. The principle of firearms has always been rudimentary.

The Gatling gun was no exception. Such machine guns are usually of two configurations. The most common is the structure of the rotation of the barrel driven by a motor, the advantage of this structure is that the rate of fire is adjustable, but because of the addition of a drive system. Therefore, the structure is more complex and the weight is relatively high.

The other is to drive the barrel to rotate through the principle of formula, because the electrical equipment is omitted, the overall weight is lighter than the former, but the rate of fire cannot be adjusted by the speed of the motor, and can only be controlled by the experience of the shooter.

The commandos are currently armed with the latter.

Because of the high rate of fire and the high amount of ammunition consumed, Gatling guns or cannons are usually equipped on warplanes or various military vehicles, and infantry is not suitable for Gatling guns because of the limited ammunition they carry. However, the machine guns and rifles equipped by the commandos are 5.5 mm shellless bullets, and the diameter of the bullet is only reduced by a few millimeters, but the weight of the barrel and the entire firearm is not reduced by a little.

In addition, the combat environment of the commandos is mostly weightless and low gravity, and the heavy load is combat armor, and all factors come together to prompt this small-caliber Gatling gun to be equipped with the commando.

With the establishment of a commando team, a detachment of seven members, five of whom use rifles, one uses machine guns, and the last team member uses sniper rifles. Modern armies are paying more and more attention to firepower, which is one of the important reasons why commandos are equipped with Gatling.

On today's battlefield, Gatling was destined to be the protagonist of the enemy's annihilation, and even though the machine gunners deliberately lowered the rate of fire, the nine machine guns still ploughed nine furrows in unison among the skeleton men rushing towards the human position.

Gatling is not a sniper rifle for accurate killing, it relies on the density of firepower, but the enemy's speed is too fast, the distance between the two sides is too close, there is no need to aim carefully, the machine gunners can sweep down one piece after another of the skeleton, easier than mowing grass.

Often, the riflemen had just taken aim at the target, and before they could shoot, they realized that the target had been knocked down by the bullets fired from the machine guns, and gradually the soldiers armed with rifles simply stopped firing and let the machine gunners slaughter the enemy with peace of mind.

However, a large number of kills also meant a rapid depletion of bullets, and by the time this group of enemies was too thin to be worth wasting Gatling's limited number of bullets, the nine Heavy didn't have much ammunition left.

The bullets used by Gatling are exactly the same as those used in rifles, but the rifle bullets are all encapsulated in the magazine, and the Gatling bullets are encapsulated in the bullet box, and there is no condition to open the magazine to replenish the bullet box, so the Heavy who runs out of ammunition will have to fight with the pistol next.

The original dense forest turned into sparse shrubs, and there were not hundreds of frightened scattered skeletons on the battlefield, and the riflemen who had rested for a long time shot all the remaining enemies in a leisurely manner, and when the smoke of the shooting dissipated, countless layers of corpses of the skeletons were left on the support column.

"Hurry up and check the ammo!" As soon as the battle ended, the monkey immediately issued a new order, but he knew very well that with the machine gunners running out of ammunition, it was extremely unlikely that the three teams would withstand the next wave of the enemy's attack, so he immediately suggested to Ye Fei that the three teams should be withdrawn from the first line.

Ye Fei agreed to the monkey's suggestion after briefly thinking about it, and ordered the first brigade of the black bear to change guards with the three brigades, and the three brigades withdrew to act as reserves.

Although the fighters were well-trained, the number of fighters was limited, and the speed of the change of defense was extremely fast, but just halfway through the change of defense, the second wave of Exoskeletons arrived as scheduled.

This time, not only the front, but also the figure of the outer skeleton appeared on several nearby support columns. They were like the one that had climbed up the rough inner wall of the bone mound, and surrounded the support pillars where the commandos were from all directions, and if they were viewed from above, it was like a dozen huge ant nests suddenly appeared on the ground, and all of them were gushing out at the same time with an astonishing number of ants.

The outer bone people who climbed the inner wall spread rapidly, and many of the outer bone people who had just gushed out of the passage could not get close to the inner wall, and even grabbed the body of their companions and climbed out, and as more and more outer bone people gushed out of the passage, the outer bone people who gushed out of the passage were piled up at the mouth of each passage, and actually formed a crater that was accumulating higher and higher!

Live crater!

What was even more surprising was that there was not only one channel connected to each support column. The support where the assault team is located is underneath and above at the same time, a large number of exoskeletons poured out at the same time!

The sight in front of them made everyone's hearts freeze instantly. Although the enemy began to fight back as soon as they appeared, so many enemies were enough to drown everyone present, and more than 200 commandos could not resist at all, unless the guns in everyone's hands turned into Gatlings with infinite bullets!

"Boss. What to do? The black bear asked anxiously as he shot.

No matter how you look at it. It was only a matter of time before the enemy broke through the thin lines of the assault detachment.

"Hold on!" Ye Fei gritted his teeth and ordered. "Three brigades defend on the spot, two brigades on the left flank, and four brigades on the right flank. Shoot me with all my might, and give me all the weapons! ”

Some of the fighters who still had strong equipment immediately dumped the few remaining shells on the top of the outer skeleton man's head, and the fighters with grenades also began to hit the enemy with various methods, and the firepower intensity displayed by the commando team in an instant directly punched the enemy's front into a noticeable depression!

However, the existing troops can only defend in three directions, and the rear of the position is blank, as long as the outer skeletons on a few nearby support pillars crawl along the surface of the core area, they can cut off the rear path of a commando team to retreat into the core area.

The machine gunners of the three major teams had already run out of machine gun bullets, and had to take out their pistols to continue fighting, and all the shells were also gone, although they had just eliminated many enemies, but after the ammunition at the end of the plug-in weapon module was exhausted, the firepower intensity of the human side suddenly dropped by several levels.

Ye Fei kept telling himself in his heart to persevere, hold on for a while, but when the outer skeleton figures on several nearby support pillars climbed onto the surface of the buildings in the core area, he clearly knew that he couldn't wait any longer.

"All attention, prepare to withdraw ......" When Ye Fei made up his mind to order the troops to withdraw into the core area, and the last word was about to exit, the inner wall of the bone mound about two kilometers away suddenly shattered with a bang, and several pieces of rubble with a diameter of hundreds of meters, I don't know how heavy the road was, slowly fell off from the inner wall, and then slowly fell, smashing heavily on the outer layer of the building in the core area in a thunderous roar, deeply embedded in the core area, like a few dried fruits pressed into the cream of a cake.

In addition to these largest fragments, there were also a large number of fragments of different volumes falling with them, the support pillar near the entrance of the cave collapsed instantly, and the pile of outer bone towers that stood as high as the crater collapsed in a blink of an eye, and I don't know how many outer bone people fell to the core area like dumplings, and a bright light shot in from the breach, and all the outer bone people who were directly irradiated by the light didn't even have time to scream and directly vaporized into nothingness.

The diffuse dust spread rapidly, quickly covering half of the battlefield, and the offensive of the Outer Skeleton Man was suddenly stagnant.

The team members in the bitter battle were like being injected with a heart booster, and they instantly burst into enthusiastic cheers.

"Bridge Shipbridge, I'm number one, please answer when you hear it, answer it when you hear it!" Ye Fei was so excited that his voice trembled, if he was more than ten seconds late, everyone would all retreat into the depths of the core area, and they would not have to worry about leaving the bone mound.

"The bridge received, number one, please speak!" He Jian didn't know the situation below the road, and when he heard Ye Fei's voice, all the bridge officers breathed a sigh of relief at the same time.

"The situation is urgent, we are already surrounded by the Outer Skeletons, we need to leave immediately!"

He Jian did not immediately carry out Ye Fei's order, but cautiously asked, "Do you need support?" ”

Ye Fei was stunned when he heard this: "What kind of support do you use?" A thought flashed through his mind, He Jian wouldn't have thought of going with him, but judging from the scale of the passage, it was not enough to pass through the assault landing ship, and it was almost double the diameter.

He Jianli immediately replied: "If necessary, I will immediately send fighter planes to support!" "He is an excellent commander from a professional background, and he has not studied land tactics much, but how to fight in the air and how to support the ground is his old profession, and he will not make jokes about sending warships directly into the bone mound, but is ready to send flexible and mobile fighters.

Fortunately, the smuggling of the bone mound was too large, and instead of digging a shaft with a drill bit, the Aquila directly bombarded it with its main guns.

Ye Fei didn't realize what he had overlooked until this time, and was secretly glad that he didn't say what he had just thought, and after thinking about He Jian's suggestion for a while, he replied: "There is a straight-line distance of more than 500 kilometers from the outside to the core area, even if the fighter plane sets off immediately now, it will be too late, and if we fire two more shots at the shaft, we will fly out of the shaft ourselves!" ”

"Understood!" He Jian didn't know the specific situation inside the Dao Bone Mound, so he naturally had to rely on Ye Fei's judgment, "Scissors-"

"Roger!" More than a dozen lasers shot out of the shaft without interruption, and the hole in the inner wall of the bone mound expanded rapidly, and the nearby outer bone people were either shot by the laser or hit by the flying fragments, and there were very few that could still be left on the nearby inner wall.

"Shoot it!" Scissors report quickly.

"One, the battleship is finished!" He Jian immediately sent the news to Ye Fei.

Ye Fei raised his arms and shouted: "Brothers, towards the shaft, fly-" (To be continued......)
