Compared to these peripheral positions, most of the artillery fire of the Revolutionary Union was concentrated on the top of the Sword Pavilion Fortress, and there was a great momentum of using artillery fire to raze the Sword Pavilion Fortress to the ground.

However, the organization also came up with corresponding countermeasures against the artillery bombardment of the Revolutionary Union - they dismantled the close defense guns on the warships and installed them on the fortress, and this kind of multi-barrel cannon that relies on the computer system for aiming can fire hundreds of shells per second, and even ballistic missiles can intercept them, not to mention the shells whose flight speed is not as good as that of missiles.

It's just that the only problem is that there are too many cannonballs in the Revolutionary Alliance, and there are less than forty close defense guns in the Sword Pavilion Fortress, which can only defend the key areas of the fortress, and there is no time to take care of those peripheral positions.

Every shell that slipped through the net caused huge casualties to the group, and the perimeter of the fortress was full of terrifying huge craters, and even a small hill more than ten meters high was blown flat by heavy artillery.

The sound of cannon fire in the sky completely drowned out the construction noise on the fortress construction site, the trembling of the ground never stopped, and from time to time there would be gravel and broken limbs splashed into the construction site, but the construction of the fortress never stopped, and the truck transporting materials ran over a severed arm, crushing the broken arm into a thin and uneven strip of meatloaf.

"The Sword Pavilion Fortress won't last long." As a bystander, Qi Lin saw the problem at a glance - the loading of shells for the close defense gun has always been a time-consuming and laborious task, even after the improvement of the ammunition supply system and the use of mechanized loading devices, this time has been compressed several times, but in the face of the overwhelming shells, it is still far from enough.

As for the BR-5 heavy howitzer, after adjusting the muzzle angle, the entire process of unshelling, loading and firing will not take more than five minutes, and if the gunner and loader are both skilled veterans, this time can even be shortened to less than three minutes.

Judging from the intensity of artillery fire, the BR-5 heavy howitzers that the Revolutionary Union put into battle this time may have more than 50 pieces, and with the continuous advance of the battle line, other artillery with a shorter range than the BR-5 will also be able to directly threaten the Sword Pavilion Fortress.

On the side of the Sword Pavilion Fortress, there were already several close defense cannons, and several soldiers wearing power exoskeletons were hurriedly loading ammunition for the close defense guns.

At this moment, a shell successfully passed through the fire net and landed next to a barracks that was being built, and with a loud bang and a strong wave of air, the barracks and the people who were building the barracks disappeared, leaving only a large crater with a diameter of more than 30 meters in place.

The blast of air from the explosion of the shell even overturned a truck 100 meters away, scattering the construction materials it was carrying.

"The artillery positions of the Revolutionary Union must be destroyed, and Comanche will send you five kilometers from the target, and the rest is up to you."

The G49 only had eight electromagnetic bombs, and if it wanted to destroy as many of the heavy artillery as possible, it had to find a way to penetrate it, so the angle of the shot was very important.

"I wish the artillery positions of the Revolutionary Union were densely arranged...... Qi Lin said, putting on Thor's hammer again.

The internal changes to Mjolnir are not big, and Cortana's voice and tone are exactly the same as they were at the beginning, except that the emblem of the Organization Equipment Research Institute on the OS interface has been removed, and the function of directly connecting to the intranet of the organization and the consortium alliance is gone.

Of course, this is also a last resort in order not to leak information, Qi Lin now wants to access the organization's intranet, so he can only let Cortana act as a hacker for a while to break in.

However, there is a mastermind, for Qi Lin, that intranet is basically equivalent to an undefended state, and there is not much difference between hard breaking and direct connection, and the latter is not as much as the former because of the problem of legal permissions.

Qi Lin boarded the Comanche α, and at the same time, Cortana broke through the firewall of the organization's intranet and consulted the relevant information about the Sword Pavilion Fortress.

"Huh...... The new Supreme Commander of the Sword Pavilion Fortress? Parliamentary carte blanche? Where did this guy come from? Opening the relevant page, a newly announced news caught Qi Lin's eyes.

"That guy is one of the nine founders of the organization." The main brain said calmly.

"Can the old guys with Qin and the gang move? Didn't the other eight lie in the survival pod and survive? Qi Lin said with some surprise, the figures of this level have all appeared, which shows that the organization's attention to the Sword Pavilion Fortress has reached the point of almost desperate.

"It's not that there's no way to get their bodies back, but in terms of the technology they have so far, it's very costly."

"At a high cost?"

"Qin directly replaced a young body, and this person's body is still in the original load, the life span of the cell has come to an end, and the price of forced recovery is that he has no more years to live, even if he lies back in the life support cabin at this time, it will be useless."

"When you say that, I think this person is very great, he is ordered at a critical moment, sacrifices himself, and sacrifices his small family for everyone, he is simply a model of the times......" Qi Lin teased while debugging the modified Thor's hammer.

"Someone among them has to step up, the puppet council can't control the situation anymore."

The exit to the underground hangar had been opened, and Comanche α smoothly lifted into the air with Thor's hammer in his hand, and then flew in the direction of the battlefield.

……

……

Sword Pavilion Fortress.

"The enemy artillery fire is too fierce! We simply can't hold on! The fortifications on the perimeter of the fortress were destroyed before they were built! The losses of workers and engineering armor were great! This point of close defense artillery is completely insufficient, and I ask for fifty more to be sent below...... No! Send a hundred close-in defense guns! A dusty officer with the rank of colonel, tattered uniform, and a grizzled officer was clutching a microphone and shouting hoarsely, his voice almost hoarse, but his voice was still drowned out by the sound of shell explosions in the background.

"Impossible, there are only a few transportation channels, materials and troops have to pass through these channels, they are already crowded, a hundred close defense guns plus ammunition and supporting equipment, it will definitely not be able to be transported for a while and a half, I can only provide you with ten at most, this is already the limit!" The man on the other end of the microphone said.

"Ten doors?! Where is this enough! ”

"I'll tell you the truth, I don't have so many close-in defense guns here, and the batch installed in the fortress is almost all in stock, even if these ten cannons I have to find a way to piece together to get them out!"

"Alas! Ten is ten! Better than nothing! How long does it take to get it delivered? "Another shell landed less than five hundred meters away, and the lime that fell from the ceiling fell on the colonel's head and back.

"Three hours, I will send it to you within three hours, so that your men can hold on for a little longer."

"Three hours? Will you come and collect our bodies in three hours? At that time, the shelling had long since ended, and the large forces of the Revolutionary Union were all about to descend on the city! The colonel shouted with great dissatisfaction.

"As soon as possible! I'll get them to get it up as soon as possible! Priority has been brought to the top! When this batch of cement and steel pipes is delivered, it is the close-in defense gun you want! The other end of the microphone is also full of all kinds of noisy sounds, and at this moment, the underground world is no less busy than the above-ground world.
