I summon heroes in the last days

As the night passed, the clouds floated white, and the sun shone on them, reflecting a yellowish color.

It's just that, at the beginning of this new day, one after another mixed with inconceivable and terrifying messages began to spread in the air.

Whether it is a known threat or an unknown terror, it all hangs over people's hearts.

Originally brought about by the appearance of the fire dragon, the hope of the people in the mountain city became blurred overnight again.

It doesn't mean how serious the problem is, but that in a series of changes, what we are about to face now is an irresistible general trend.

"That's how it is."

"Now there is no accurate news everywhere, and the normal communication channels have been cut off, and we can only contact through dedicated lines."

"However, this method is also unstable."

Guo Ziming stubbed out the cigarette butt, his face was a little ashamed, "Also, according to the news that has been obtained, the monster's field has spread again, and now it has reached the gate of Zicheng."

"There is news that a medium-sized base city in the south has been covered by the domain, and tens of thousands of people died that night. If you don't escape as soon as possible, there will be more deaths later."

"More than that!" Guo Weiliang next to him continued, "This field is expanding so fast, and with the influence of the particles emitted from the field, it is estimated that more than half of the planets will be affected. In this way, those who were originally scattered and remained It's dangerous."

People around felt uncomfortable hearing this. Although they were not the ones who were harmed in the field, judging from this trend, they would not be able to escape the fate of being shrouded sooner or later.

Xiao Feng's complexion was even more serious, and there was no other reason, the situation in Zicheng was the first to bear the brunt, maybe it would be covered by the domain in one night.

And his Tiger Legion is in Zicheng, and the panic in Zicheng can be imagined at this time.

Although he believed that Guo Jia would deal with it properly, as the backbone, if he could not go back to stabilize the morale of the army as soon as possible, it would be a blow in disguise to everyone in the Tigers.

"We must end the battle here as soon as possible, and go back as soon as possible!"

Making up his mind, Xiao Feng looked around and saw that everyone looked worried, even more depressed than when he switched to battle but went underground.

Just when Xiao Feng was about to break the atmosphere, there was a rush of footsteps from outside, and then a flustered soldier in military uniform ran in.

Facing the soldiers who broke in suddenly, a scene that should not have happened on this occasion appeared. As the leader of the military, he immediately stood up and prepared to ask questions, but was interrupted by the panicked tone of the soldiers at the next moment, and the figure stopped and was at a loss. .

"Report to the commander-in-chief, it's not good, the carbon dioxide content in the dungeon air is continuously increasing, and it's almost approaching the warning line!"

The soldier spoke quickly, and the other people on the side were still a little confused, but the expressions of Guo Weiliang and many officials in the mountain city changed drastically.

When building a dungeon, various dangers and possible problems were considered. Among them, air, or oxygen content, in layman's terms, air circulation is the most important issue.

Therefore, in order to solve this problem, the mountain city arranged many air outlets when the underground city was built. These air outlets are large and small, and for the sake of privacy, some of them are arranged in the buildings, and some are connected to the sewer in the city. Then there are some hidden ground facilities.

Knowing the importance of air circulation, not to mention the huge area of ​​the underground city and the large population, if something goes wrong, it will be a catastrophic level.

Therefore, Shancheng specially set up an air supervision department, and the soldiers who rushed in at this time were members of the supervision department.

Because of this, after he spoke, Guo Ziming and others' already serious faces became even more ugly.

"what happened?"

Guo Weiliang asked calmly.

The soldier calmed down and said immediately, "Not long ago, the concentration of carbon dioxide in all the air samples collected in the dungeon was more than ten times higher than the previous detection. If it continues, the oxygen content will continue to decrease, and the consequences... ..."

The soldier didn't finish speaking, and everyone knew it in his heart.

In this underground place where there is no sunlight and photosynthesis is missing, the cycle of absorbing carbon dioxide to produce oxygen cannot be used. The main source of oxygen that people need is the outside air. As for the oxygen produced by chemical reactions, it can only be used as a last resort.

At this time, the increase of carbon dioxide can only indicate that there is a problem with the air circulation with the outside world.

If this is the case, the entire dungeon has a large population and is undergoing metabolism every second of every day. If this problem is not solved as soon as possible, many people will probably "suffocate to death" after a long time!
However, before the people around asked why this happened, the kidnapper who was in charge of inquiring about the news also rushed in.

The people who had been prepared for a long time were not surprised, and Wang Junhai on the side immediately asked, "What's wrong?"

"I just saw that the tauren above are destroying our air outlets one by one."

Kidnap said quickly.

"Impossible. Our exhaust holes are all specially designed. Most of them are built into the wall and directly connected to the roof. How can they be found? Even our construction department can't figure out how many there are. where!"

A government official immediately stood up and asked in disbelief, and at the same time made it clear that there was no such thing as a "traitor informant" drama.

The kidnapper ignored him, turned his head and said, "I found that in these areas, things like domains will temporarily appear one after another, and then there will be tauren dedicated to destroying the air outlet."

Everyone was dumbfounded for a while, and the official who couldn't believe it before lost his confidence. After all, there are many bad things now, and no one knows what special abilities the tauren has.

"They must be stopped immediately!"

Suddenly, Guo Ziming shouted loudly.The voice was full of urgency, and as the voice came out, everyone turned their attention to Xiao Feng.

At this moment, they knew that the only way to prevent the tauren from destroying the gas outlet was to rely on Xiao Feng and the others.

Xiao Feng originally wanted to end this operation as soon as possible. Although he was not completely sure, he believed that without the restriction of the bird man, their combat power could be fully utilized. In addition, the fire dragon summoned by He Qing, even without using skills, Just letting the fire dragon fight with its own body can deter the tauren.

Thinking of this, Xiao Feng did not disappoint everyone, and immediately stood up and said, "Time is urgent, Mr. Guo, you arrange the staff, and we will act immediately."

"Okay. Take out all the money this time."

Guo Ziming said bitterly.

Hulala, a group of people walked out immediately.

After a while, the team organized by Shancheng gathered.

Xiao Feng came to the side of the team. There were not only many people with different abilities, but also a group of soldiers with flamethrowers in the assembled team.

Xiao Feng is not a novice, he knows that the flamethrower in front of him is definitely a weapon with extremely high lethality, even in this era, facing monsters is also somewhat lethal.

Guo Weiliang said on the side. "This is our mountain city's last trump card. The entire army uses the latest individual flamethrowers, with a maximum range of 120 meters. The flame intensity can easily burn people into carbon ashes."

Xiao Feng looked at the more than 80 people in front of him, each of them was a tall evolutionary. They were wearing military uniforms, and they had no other weapons, only a flat barrel about one meter behind them, and a gun in their gloved hand. Tube.

There was firmness in his eyes, no fear at all.

You know, in the modern army, although the Pyro is powerful, it is a high-risk unit.

After all, being hit by a bullet is just a hole in the body, and it's just a death.

But if the flamethrower was blown up by the enemy, then he would definitely not have to run, and he would have to bear the tragedy of being burned by the flames first.

Moreover, the distance of the flame spray is not long, and the duration is only about 10 minutes. Under the threat of the bird man, he dare not use it at all.

Now that the birdman is gone, it can be taken out.

However, Xiao Feng still admired these people very much. After all, anyone who appeared on the battlefield with a big terror on his back would not be able to do without a strong psychological quality.

clang clang

With a wave of Xiao Feng's hand, hundreds of heavy infantry shields appeared on the ground, causing the eyes of the surrounding people to shrink.

"Mr. Guo, please arrange some people to immediately shield and follow them."

Xiao Feng knew that if he wanted to open the gap as soon as possible, he needed these Pyro soldiers to rush out, and once these people appeared in the eyes of the tauren, they would definitely be the first targets of attack. , The people around can't please.

Guo Ziming also realized this, and with a wave of his hand, another hundred people ran out of the army behind him, raised their shields one by one, and followed the Pyro.

Xiao Feng glanced at the other people around him, and everyone knew about the upcoming battle, which would also determine the fate of the mountain city.

"Don't talk too much, at this moment, only a death battle can have a chance."

Xiao Feng was full of fighting spirit, and his whole person's momentum exploded, holding the fine iron Yanyue knife in his hand, and his eyes were shining brightly.

"I order!!!"

As the voice fell, no matter whether it was a mutant or an evolutionary, no matter whether it was a government official seeing off or a military soldier going on an expedition, all stood upright, waiting for orders.

"Ma Chao, lead the first team to rush out immediately and stand firm."

"promise"

Ma Chao was holding a brocade spear, and his aura was stronger than Xiao Feng's, and his high fighting spirit made Long Da Chu Qiannan and others behind him full of fighting spirit.

""Wang Junhai, lead the second team to go out in the second wave, depending on the situation. "

"Yes!"

With a tall and straight body, he returned to the team after a military salute.Behind him, Wang Qiang Guofeng was also excited, and the weapon in his hand was tightly grasped.

"Guo Weiliang, lead the Pyro for support."

Guo Weiliang stepped forward with a shiny bald head and gave orders loudly.

Seeing that the assault force had been properly arranged, Xiao Feng turned around and saluted Guo Ziming and shouted, "Report to the commander-in-chief, the assault force is ready, please attack!"

Guo Ziming returned the salute, and then the more people came out, he ordered loudly, "Allow to attack."

"Yes!"

Xiao Feng shouted again,

"The commandos will attack step by step. This time, we will defeat the tauren with dignity! Take back our city!"

"kill!!!"

"kill!!!"

"kill!!!"
