But when it was discovered that the walls of the 4 weeks were not corroded at all, the monster that had reached the three mutations once again put its sights on the ground.

For example, a huge hole has been dug out of the ground from the beginning, and the height and width can almost encompass the entire core.

The core itself is made of steel at the bottom and has a foundation underground, so this causes the monster to dig down until it reaches the part of the foundation after several meters.

Faced with 4 weeks of no way to besiege and corrode the core, there is one of the biggest problems at this time.

The space that was supposed to be above the core collapsed to block the No. 1 and No. 2 defenses, but because I blamed myself for cleverly opening up an underground passage, it didn't play any role in blocking at all.

But at the same time, because of the collapse of the No. 1 and No. 2 defense lines, it also led to the external defense of the entire core, which was not so perfect, because the pressure caused by the collapse caused certain cracks and bulges in the foundation below.

The monster doesn't know the structure of the building, but it only corrodes itself from the weakest point of the building and can't hit it, so it just happens to corrode along the key points of the foundation.

And the No. 3 defense line, which was constantly stopping the monster core from pouring out, because of enough firepower, these monsters couldn't break through the defense line at all, and their ammunition was still 10 points sufficient, if it could continue like this, then there would be no problem at all to support it for a day.

And the strength of the monster impact was also much less than before, and just when everyone was relieved, something happened that everyone didn't expect.

First of all, the ground began to tremble slightly, and at first everyone didn't care, thinking it was just a slight tremor, but then the amplitude of the vibration seemed to be a little too huge, and when the chief of staff also felt that something was wrong, he opened the detection of the object's underground, but found that there were a lot of red dots below at some point, and these red colors naturally indicated that they were monsters.

And when the happy red alarm was detected, the floor plan of the entire core of the higher-end detection device was instantly opened, and it was set up in front of the chief of staff in the form of virtual projection, and it had completely become a hole underneath, leaving only the only foundation on the pillar.

Although the foundation is very strong, the monsters are constantly corroding the foundation, and according to the corrosion, it seems to have reached 13.

And the shaking degree and turning degree of the entire ground are still increasing, and the constant shaking makes the accuracy of the soldiers' firepower decrease to a certain extent, but the walking speed of the monsters and the number of rushing out have also decreased a lot.

"Quickly calculate how long the pillars below will be able to hold up, and what will happen to us if the load-bearing pillars break...", the chief of staff frowned slightly, and walked back and forth with his hands behind his back, looking uneasy.

"Chief of Staff, what are we going to do? The ground has been corroded by monsters, and if the foundation cracks, the massive collapse will cause the entire core to fall into the big hole below!

According to calculations, if the whole thing collapses, the walls around us will break and will not be able to withstand the impact, and because weightlessness will put us into an upward force that may hit the ceiling

This could cause some casualties, and at the same time cause serious damage to the weapons, and the whole position would become chaotic, and if those monsters took advantage of this time to attack from the entrance on a large scale, we could..."

After thinking about it, the chief of staff directly gave the order to send the message to all the soldiers' information receiving devices, which would also allow all soldiers to prepare for the shock in advance.

Because there is really no other way to stop the monster from corroding the load-bearing pillar, if there is one, it would have been carried out a long time ago, how can it be like this fate of sitting still, and now I can only think of an order, let all the soldiers find a way to fix the heavy weapons, as well as their own fixation, so that when they fall later, at least there will be no chaos due to the sudden impact.

But it's a pity that not all soldiers can have time to fix, because the crawling speed of the monster is violently shaken, and the entry speed has also been reduced and weakened to a certain extent, which leads to the entire entrance, so that the ordinary fire network is enough to kill the monster, but when the other soldiers are fixed, there must be some people who keep firing to contain it.

to make sure that the monsters do not break through the defenses, and at the same time, a red countdown appears on the bracelets of all soldiers, and there is less than an hour left.

This time is the time when the adjutant is about to withstand the collapse according to the speed of the monster's corrosion, and the changes and actions made by this series of monsters really make the chief of staff feel frightened.

At the same time, it also made the chief of staff more and more determined to destroy this monster that had reached the third mutation, because the monster with wisdom was too terrifying, and the chief of staff had deeply understood this.

Line 3 is at the forefront

"The time is almost up, you should also hurry up and fix it, now the firepower in this area is enough, if it is not fixed, the time may not be enough" A soldier on the side wiped the sweat on his face tiredly, but his hands never left the trigger of the weapon, just picked up and wiped with his arm, and looked at a comrade who was still fighting on the side and persuaded.

"No, it's better for you to fix it quickly, I'll cover for you, and if you don't set the time, it's really too late..."But the comrades-in-arms on the side just cracked their mouths and smiled, the dust on their faces was not wiped off, mixed with sweat, it looked a little dark and had a strange smell, but I didn't care, my eyes were always staring at the front entrance, although this road crossing was still expanding, but there was no way to break through the fire network.

Both of them were courteous to each other, but neither of them was fixed in action, and all of them focused on the invading monsters.

"Hehe, it seems that you think the same as I think, in that case, then buy time for them, anyway, it doesn't matter if they die or not, and they won't necessarily die because of the sudden shock, anyway, it's also a mutation, but they won't die so fragile." The soldier on the side wiped his nose, lowered his head and used his wrist to gently wipe the dust and sweat from his face.
