By this time, the defenders had also felt defeated, and a large number of soldiers on the upper floor began to run downward, gathering on the first, second, and third floors.

If this building collapses, if anyone is still on the upper floor, it will definitely be impossible to escape death. Now that the attacking forces are approaching, staying in the upper echelons any longer is definitely an act of seeking death.

However, the defenders did not give up resistance. There are only ten minutes left until the end of the mission, and as long as they can survive those ten minutes, then they win.

Now all the firepower is compressed together, so that many soldiers can have a short rest, and the firepower within the third floor of the building is starting to become tenacious.

But in this way, they also put much, much less pressure on the attacking troops. Without the overhead firepower, many places that could have been attacked have completely become safe bunkers, the attacking troops' lines can be stretched wider, there are more and more firing points, and the pressure on the defenders has begun to increase.

Especially in the direction of Sima Yun, the pressure has been greatly reduced, and the firepower is more ferocious.

Everyone knows that we have now entered the most critical moment. By now, all the troops have become supports, and the protagonists are still those rocket soldiers with bazookas, as well as demomen like Sima Yun.

At this time, the battlefield was full of rockets and grenades, and the formation looked like there were more rockets than bullets, and the large smoke even blocked part of the vision of both sides, and even people couldn't see it clearly.

Sima Yun is still the Demoman closest to the government building, and his attack power is also the highest unit in the vicinity outside of tanks. More than half of the bombs on his body had been dropped. And on this side, basically one-third of the outer wall was blown up by him alone, so it can be said that he alone withstood almost five fires of 40 fires over there.

The support troops over there were also fighting, three boxes of grenades were being consumed rapidly, and everyone was about to run out of grenades. These grenades also played a great role. By now, the first layer of the outer wall on this side has been completely demolished.

The destruction of the façade, which affected the overall balance of the building. Although this building is big oh oh there is no sign of collapse yet, but it depends on the situation. It didn't last long, either. The first and second floors had been completely destroyed by them, and even the cracks that stretched to the surrounding area had extended as far as five stories high. Take a few more hits, or find a layer of load-bearing columns to blow it up. There is an 80% chance that the building will fall down.

At this time, Sima Yun was holding a bomb in his hand. But it was not thrown out for a long time. Through a small hole in the ruins, the eye observes the situation and structure of the entire first floor of the government building.

Their own actions have been completely successful, but the building has not yet fallen. If it continues to be blown up like this, I'm afraid the building won't collapse. So Sima Yun's goal changed, and he put it on the load-bearing structure of the building.

He was observing, observing that the walls and columns would be the load-bearing structure of the building. As long as they can be demolished, the building will not survive.

Now the building is very broken, and the façade of the first floor here is gone, and the center of gravity is strictly offset. As long as any of the load-bearing parts on this side are demolished and destroyed, it will further affect the center of gravity of the building, and at that time, the building will be directly crushed by its own weight.

Leave the rest of the destruction tasks to the others.

After scanning the first floor of the building in this direction, a rough structural diagram of the government building appeared in Sima Yun's mind little by little, and at the same time began to calculate which structures would be used to bear loads.

This is a science that Demomen must learn, they need to destroy as many targets as possible at the minimum cost, and he also has some delving into the structure of buildings. After a while, Sima Yun stared at a large pillar as thick as three hugs.

In the structural diagram in his mind, Sima Yun figured out that this pillar is one of the load-bearing structures of the building, and it is very likely to be the pile foundation structure of the entire building, which is buried deep in the ground below to play a certain load-bearing and anti-deviation object. But he didn't have the time and time to fully confirm whether this thing was his target, so since he was eyeing it, Sima Yun began to think about how to blow it up.

Calculating the distance, Sima Yun adjusted the bomb to manual detonation, then grabbed the C4 bomb and shook it twice in his hand, then held it, suddenly popped out of his head, and threw it out.

But when the bomb had just been taken off, a blood splash immediately appeared on Sima Yun's chest.

It turned out that there were two defenders who had been staring at Sima Yun's actions, and when they came forward, the two immediately opened fire.

It was only at this time that Sima Yun felt the pain, and then his legs went weak and he fell to the ground.

But the two defenders were also a little slower. The C4 bomb had already flown out of Sima Yun's hand and flew straight through the big hole in the wall into the government building.

Sima Yun's strength was very strong, and with this throw, he directly threw the bomb dozens of meters away. Like the previous bomb, this one flew into the government building and was pinned to the pillar.

"Ahem!"

Sima Yun coughed, and suddenly a piece of blood was coughed up and sprinkled on the combat uniform.

Seeing that he was shot, Wei Gong ran out without hesitation and wanted to be rescued. But as soon as he came up, a large number of bullets hit him, forcing him back to the same place.

Zhang Tianhai was also anxious: "Explosive ghosts!" Got a reply! ”

But Sima Yun didn't speak at all, and he still held the detonator of the bomb in his hand.

Underneath him, the blood that flowed from the wound had formed a pool of blood on the ground.

Sima Yun smiled faintly bitterly. I'm the first to go out.

But now he was quite conscious. The defenders must have discovered the bomb, and they should be scrambling to defuse it.

But Sima Yun won't do what they wanted.

The detonator was still in his hand, and he glanced at it, then pressed the button with all his might.

"Boom!"

The bomb exploded. This explosion had an immediate effect.

As the bomb flew past, it crossed a parabola and stuck to the bottom of the pillar. At this time, the bomb exploded, directly breaking the pillar that was hugged by three people.

The underside of the pillar is broken, but the top is still connected to the ceiling. The ceiling is not as strong as this pillar, and this pillar is so thick, and its weight is not light. The next moment, a large number of cracks began to appear where the ceiling and the pillars were connected. In the blink of an eye, the large pillar also broke the ceiling above the head, and a large part of the ceiling was torn off by the large pillar and fell to the ground.

At this moment, the whole building could not hold on.

The big hole in the ceiling started to have rubble falling down the ground, making the big hole bigger and bigger. Eventually, implicated in the wall next to it, a large crack spread to the wall. After a few seconds, the wall couldn't hold on and shattered one piece.

It was this small piece of broken place, but a lot of rubble and cracks appeared, and finally the wall collapsed and fell.

Then, like a domino, the whole building began to collapse in large numbers. The tilt of the building began to become strict, and little by little it leaned in the direction of Sima Yun.

The building's own self-weight also implicates the entire load-bearing system, and many load-bearing parts are directly torn off by the building's inclined center of gravity, which accelerates the speed of the building's tilt. After a while, a huge crack appeared in the exterior wall of the third floor of the building, which tilted even faster.

In a matter of seconds, the building was about to collapse.

The collapsed building obscured the sunlight overhead. Sima Yun glanced at it, then smiled.

I succeeded, and this building was damaged by myself.

At this moment, an indescribable sense of accomplishment appeared in Sima Yun's heart.

Glancing at his teammates, Sima Yun said hoarsely: "I'll go first and go out to watch a play." ”

Wei Gong, Zhang Tianhai and others were also within the scope of the collapse of the building at this time, and they all looked at Sima Yun with ugly faces.

Then, Zhang Tianhai waved his hand: "Let's go!" ”

Sima Yun couldn't save him, even if he could be rescued from the inclination of the building, the injuries on his body would spread and run away.

At this time, it would be a fool not to run. Sima Yun is no longer saved, if he continues to dwell on this issue, then the lives of his group of people will be given away in vain.

Regardless of whether there would be bullets chasing after them, everyone emerged from behind the rubble and ran desperately towards the side of the building.

The support troops on the other side also threw all the bazookas and grenades, and then ran to the safety of the outside without their lives.

"Boom!"

The building is falling faster and faster. Finally, with a loud bang, the building fell to the ground, and the entire building fell to the ground, which was immediately shattered and stirred up a large cloud of dust.

The ground was also shaken by the falling earthquake of the building, and some of the people who were close to the ruins were even shocked by the shaking and fell directly to the ground.

Escaping the crisis of the collapse of the building, Zhang Tianhai did not stay here anymore, but waved his hand: "The task is complete, let's get out of here!" ”

The government building has been successfully destroyed, and the next thing to think about is to retreat.

Within ten minutes, your allies can't take action against you, but the defenders can. And the black saber is now in a difficult situation and has become a dilemma.

The collapsed building separated itself from the Chinese troops, and if you want to get there, the defenders in the ruins of the government building will never watch you run back to your own position, so you can't leave here. (To be continued......)
