Gas masks cannot completely filter out poison gas, and soldiers inhale poison gas with every breath.

Although it was not as much as normal, he would still die if he continued to inhale. The front-line commander knew that he could not stay here for too long. If he was not killed by the monster, he would be poisoned to death.

"Cover each other and evacuate in an orderly manner!"

The poison gas was getting more and more intense, and the officers knew they could not delay any longer, so they could only shout for evacuation.

Lu Chengchuan stood in the poisonous gas, with cyclones surging around him. The poisonous gas could not get close to him and could only swirl around him.

Just as the army was about to withdraw from the defense line, a strong wind blew from the rear of the position, and the poisonous gas seeping from the ground was blown forward by the strong wind.

In less than ten seconds, driven by the strong wind, the dangerous poisonous area moved forward a hundred meters.

Without the dangerous poison gas, the soldiers did not need to retreat. They still blocked the monsters on the defense line. Some soldiers who were seriously injured by the poison gas were urgently transported to the rear.

"Don't worry, hold the line!"

Lu Chengchuan rushed to the right line of defense, where there were the most monsters and the most soldiers who were poisoned.

He stood in the front, blocking a large number of monsters by himself, buying time for the soldiers behind to catch their breath.

The罡气 was everywhere, and Lu Chengchuan did not hold back. There was not a single living monster within a hundred meters around him.

Without the support of powerful monsters, these ordinary monsters posed no threat to him. Lu Chengchuan could kill hundreds of monsters with just a wave of his sword.

With him blocking the front, the soldiers in the rear had plenty of time to organize a defense line.

Time passed by minute by minute, and the battle continued. The temperature in the desert was high during the day, and the soldiers' sustained combat capability was greatly weakened, so they needed to be replaced frequently.

But the monsters didn't give them a chance to switch defenses safely, and there were always casualties every time the team changed.

Lu Chengchuan didn't know how many monsters he had killed. The yellow sand around him was dyed black by the monsters' blood. The corpses piled up high and then collapsed, repeating over and over again.

The battle continued into the night, and the tide of monsters finally receded.

"call..."

Lu Chengchuan let out a long breath, looked around, and deep fatigue appeared in his eyes.

He didn't know how much time had passed, nor how many monsters he had killed. He only saw the sun set and night fall, and then the monsters slowly retreated from the defense line.

At around ten o'clock in the evening, the rapid reaction force arrived at the defense line.

The defense line was reinforced, and the wounded soldiers could finally be evacuated and the exhausted soldiers could rest.

After watching monsters on the front line for a whole day, even Lu Chengchuan was tired. If he fought for another day, his internal energy and physical strength would probably be exhausted. He had no choice but to run.

"I dealt with the Corpse Demon King. Only one monster escaped."

Late at night, Zhou Yaning, Lin Jing and others gathered in the tent of the rear military camp. Zhou Xiaoling arrived in the morning, and Lin Jing and others came in the afternoon.

The two teams joined the battle as soon as they arrived, and only now have time to meet each other.

Lu Chengchuan took out the crystal and placed it on the table. The soul of the monster inside was still rampaging, trying to rush out.

"What is this thing?"

After fighting for a whole day, everyone was exhausted both physically and mentally, and some team members were injured. Now they saw a ferocious creature rushing around inside, and they were frightened again.

"It's the soul of a monster, bound in crystal by me." Lu Chengchuan replied.

The transparent crystal was placed on the table, and the monster spirit attacked it frantically, but it could not shake the crystal even a little. Unless someone smashed the crystal, or let the monster spirit pound on it for a hundred years, it would not be able to escape.

Zhou Yaning and the others were so shocked that they opened their mouths wide, looking at the twisted black mass in the crystal. Zhou Yaning looked up and asked, "Souls, monsters, are there such things?"

"Not only monsters have it, humans have it too, many creatures have it."

Lu Chengchuan's words were very plain, but everyone was extremely surprised when they heard them.

Soul, does this thing really exist?

However, monsters and superpowers have appeared, so it is not surprising to find that humans and monsters have souls. Everyone is even more surprised that he can capture the souls of monsters.

"The powerful monsters have been dealt with temporarily, but now we still have to consider the number of monsters and their toxicity.

These are not issues we can resolve. Researchers are currently studying the poison gas. Several large forces will arrive tomorrow, along with various supplies and support."

Lu Chengchuan dealt with the Corpse Demon King and other powerful monsters, but they still had a lot to consider.

"The army will handle these things themselves, and we just need to go to the battlefield."

These armies had already thought about it. What they wanted to think about was how to survive the attacks of monsters and at the same time block as many monsters as possible.

"Be careful, there are too many monsters and I can't take care of you."

There are too many monsters and they can never kill them all. They still don’t know what’s on the other side of the metal gate.

The army sent a reconnaissance plane to investigate, but the area was covered in poison gas and the reconnaissance plane could not capture any useful images.

Just as they were chatting, a lot of gunfire suddenly came from behind the base.

"It's the city. The gunshots came from the city."

Everyone was stunned for a moment, and Lin Jing quickly realized that something had happened in the city.

"Captain, this is bad! Captain, monsters have suddenly attacked Alk City from behind, and now the city is full of monsters!"

Just as everyone was thinking about it, one of Lin Jing's team members brought shocking news.

They were sniping the monster army in the front, but a large number of monsters still rushed into the city. Fortunately, there were troops guarding the city, otherwise the city would have been easily occupied by monsters.

"Which direction did they enter the city from?"

"To the northwest, they took a long detour, and there were no troops guarding that area..."

Just as Lu Chengchuan had thought before, they fought to the death here, but the monsters still rushed into the city.

"What should we do now?"

When monsters enter the city, will they still stop them on the front line?

"Wait for orders. We can't act rashly now." Zhou Yaning asked everyone to stay in the tent. They couldn't act on their own. They should wait and see what plans the command center had.

They didn't have to wait long before an officer came running over.

"Captains, the commander has ordered your two squads and the special operations brigade to return to the city immediately for support."

The order came that there were too many monsters in the city and the remaining troops alone could not stop the monsters. If they did not go back, the residents of the city would be in great danger.

The special operations brigade has assembled. They are only five kilometers away from the city, not far.

"You guys go with the special operations brigade. I'll go take a look around the city first."

Lu Chengchuan took the lead and Zhou Yaning and others nodded and followed the special operations brigade.

A few seconds later, Lu Chengchuan returned to the city. At this moment, the city was brightly lit, and the streets, big and small, were filled with monsters and soldiers.

The battle in the city was as brutal as outside, and the soldiers defending the city gritted their teeth and held on under the attack of the monsters.

Fortunately, the roads in the city are complex and provide a lot of cover. If they can hold on for a few more minutes, they will receive support.

Lu Chengchuan came to a street full of monsters, where dozens of soldiers were struggling to hold on. He rushed into the middle of the monsters and killed all the monsters in the street with a few swords.

"Captain! Someone come and help us!"
