"Bang!"

A sulfuric acid cannon slammed into the front of the city wall, and the splash of acid caused a member of the team who could not dodge to fall into a deep trench and let out a bitter cry of pain.

"Bang!"

Just above the people's heads, two hot air balloons floated with fire, and the entire back of the sulfuric acid cannon exploded, and the scattered acid caused the surrounding Amida protozoa to be harmed.

The sky is still the world of human beings, and even if it is just a simple hot air balloon, this condescending advantage has also brought great help to people.

However, on the ground, Leng Hao and the others could only helplessly retreat step by step.

The women worked hard, Yang Nannan, Xu Manli, and their hands even wearing gloves became bloodstained, but the trench dug by manpower was still too shallow.

This trench, which is almost half a man high, with long-range weapons, is a good protection measure, but it is only a helpless choice for the rat expedition team, which is now short of guns and ammunition.

"Ahhh

Leng Hao, who was wearing Xingtian's arm guards, brandished his war knife and hacked to death an Amida's protozoa that rushed into the trench, shouting a little frantically.

"Captain, retreat!"

Li Da hugged Leng Hao and dragged him back.

The only benefit of these crutches and furrows now is to facilitate the retreat of the people.

Using the corner terrain can briefly create Leng Hao, Liu Siyuan, and these fierce men have the opportunity to face a single monster.

Men with a strong body and nowhere to use can slash dozens of monsters in a matter of minutes and then retreat.

This kind of struggle has little effect on the huge number of Armida protozoa, but it is the only way people can resist.

Seeing that more and more Armida protozoa began to pour into this trench, Leng Hao could only choose to give up.

Just as Leng Hao and the others were running towards the trench behind, a frog monster suddenly jumped up from next door to another trench, and the long tongue that ejected hit one of the team members next to Leng Hao to the point of blood splashing his face.

"Xiao Zhang!"

When Leng Hao turned his head angrily to avenge his comrades, he found that the frog monster had disappeared into the trench next door to them.

These trenches, which were originally dug by people to create a sense of distance, have become the best cover for frog monsters in disguise.

"Retreat, retreat!"

When the number of team members who unfortunately died in the battle exceeded five, Leng Hao could no longer bear this kind of loss, so he could only retreat to the towering fortress wall with all the remaining troops.

"Bang!"

"Bang!"

All the ammunition reserves of the Rat Expedition were handed over to Ma Tian and them in the hot air balloon, and only their sparse and accurate gunfire could prove that the people were still resisting.

"Whew, whew."

Not only Yuan Xiaoguang and the other veteran team members under the leadership of Leng Hao, but also the new refugee team members led by Tao Xinyang were also gasping for breath on the city wall at this time.

They have just joined the battle as well, and these newcomers are gradually integrating into the team with practical actions.

"Here ......

At the sound of Leng Hao's words, a frog monster jumped out of the last trench and strode under the towering city wall, clawing at the reinforced concrete wall with its degraded claws.

Behind the frog monster, a large group of dense monsters crossed the trench and slammed into the city walls like a tidal wave.

"Shoot! Everyone's aiming to fight! ”

With Wang Wei's shout, the people on the city wall grabbed the nail guns piled up around them and began to shoot at the top of the heads of these monsters.

"Smack!"

"Smack!"

In a series of mechanical impacts, many of the Amida Protozoa Heavenly Spirit Covers burst open, and the whole person fell to the ground softly, becoming a ladder for other people of the same kind.

"Hahaha, it's actually not difficult."

"It's still the captain that they have a way, and if we do this, we can kill at least a hundred monsters."

Some of the new refugee team members were smiling as they shot.

"Bang!"

At this time, a water bomb from a sulfuric acid cannon rushed up the city wall and hit the team of overly excited newcomers.

"Ahh

"My eyes, my eyes!"

At least three of the newcomers, who had no sense of dodging at all, were corroded by most of their bodies and screamed in pain.

"Spread out, spread out!"

"Follow our actions and don't shoot in one place for too long!"

Wang Wei: Their shouts echoed across the city walls.

And Leng Hao raised his head very dissatisfied, what is the matter with the balloon team in the sky? Shouldn't these sulfuric acid cannons be completely eliminated?

But when Leng Hao saw that not far from the city wall, near the trench, there was a dense group of sulfuric acid cannons like a wavy line, Leng Hao could only swallow the saliva in his throat.

"Spread out! Disperse! ”

At Leng Hao's shout, a green water bomb shot into the air and hit the towering city wall, and those corrosive acids flew in all directions.

"Shoot, shoot!"

Ma Tian in the hot air balloon was so anxious that his eyes were about to burst into flames.

Where did these dense sulfuric acid cannons come from, and why are there so many at once?

There is a limit to what the human eye can see, and it is not so easy to discern a valuable target among such a large number of similar targets.

Just as Martin was aiming and pulling the trigger, suddenly the hanging basket under him suddenly trembled.

"Ma Tian, you guys hurry up, rise up!"

Looking at the acid bomb that hit the bottom of the hot air balloon, the people on the city wall screamed in a hurry.

"Bang, bang!"

The sulfuric acid cannons, which sat on all fours and arched high on their backs, constantly sprayed water bombs with extremely corrosive liquids.

Under this firepower, the people on the city walls were in disarray.

"Nima's, can't you use those shooting rooms under the city walls?"

"No ammunition, that kind of room, the nail gun doesn't have enough range!"

Hearing Wang Wei's answer, Leng Hao was so angry that he slammed his fist on the cement floor.

"Leng Hao, we can ask someone to throw the coal mine down through those shooting holes, and we have a high-pressure water cannon!"

Just when Leng Hao was a little depressed and could only wait helplessly, a crisp female voice sounded behind him.

Leng Hao turned his head and saw that Zhao Chenchen, who was a little weak, was standing behind him, the woman was carrying some food on her back, and she seemed to have joined the logistics team.

"What are you doing here? It's dangerous here. ”

Zhao Chenchen smiled: "Since everyone is ready to live and die with this base, what is not dangerous." ”

Behind Zhao Chenchen, the injured Tang Yida, who had just finished examining the wounded, appeared on the city wall one after another.

"Everyone eat quickly, and only after eating can you have the strength to continue fighting."

"It's not that easy to occupy our walls!"

Looking at these comrades-in-arms who were still wrapped in straps and limping when they walked, the somewhat hesitant eyes of many people gradually became firm.
