Hearing the question of the girl in red, Lu Jun thought for a moment, and slowly took out a large number of dense fog grenades and distributed them to the surrounding women.

"They can't get out now, they must be panicking in their hearts, it's a good time for us to launch an offensive, but we can't rush out directly, because the opponent's firepower is very fierce, we have to throw a lot of dense fog grenades as cover first, under the cover of dense fog grenades and darkness, we will definitely be able to hit it with one blow." Lu Jun said his thoughts as he handed out grenades.

"Then the four of us will attack directly? Don't wait for the wood to them? Ruan Bing looked at the dense fog grenade in her hand and asked her question.

"Wood, they should have about ten minutes to rush back, let's attack first, time waits for no one, and the effect of attacking now is the best." Lu Jun affirmed his thoughts, and his eyes also revealed resoluteness.

Seeing this, Ruan Bing and the others stopped talking and began to check their weapons and make final preparations.

After there was no problem, Lu Jun led the women forward for more than 200 meters, and then threw the first dense fog grenade in his hand, letting the thick white fog cover their advance path.

The Ruan sisters and the girl in red did the same, throwing two dense fog grenades every twenty meters or so, using this method to slowly move forward.

The defense forces standing around the research institute also noticed the dense fog rising not far away, but due to their field of vision, they did not know how the dense fog came about.

Some of the more resourceful defenders also used high-intensity flashlights to shine in the direction of the dense fog, but they failed to find anything unusual.

Seeing this, the person in charge of the scientific research institute couldn't sit still, and immediately gave an order, asking the city guards to fire at the dense fog with all their might, wanting to see what strange things were in the thick fog.

Hearing the order of the person in charge, the city guards naturally did so, using their own guns and all kinds of heavy weapons to form a network of firepower, covering the entire area of the dense fog.

And the road army in the dense fog saw that the city guards were firing, and he didn't panic at all, because he knew that the people in the scientific research institute couldn't see him, and most of them were shooting indiscriminately, so he just slightly propped up a particle shield to protect the women, and didn't spend much brainpower.

In this way, although the firepower of the city guards was very fierce, and rockets and bullets constantly flew past the road army and others, very few of them could really hit the road army.

Even if a bullet happens to shoot at the location of Lu Jun and the others, they still have a particle shield as protection, so they will not be injured at all.

Seeing that the city guards had consumed a lot of bullets but did not achieve the desired effect, the Lu army was secretly happy in his heart, and continued to throw out the dense fog grenade in his hand and slowly move forward.

And after a round of ammunition, the people of the city guard found that the dense fog was still spreading, and it was not affected in the slightest, but was getting closer and closer to them, and they immediately panicked, not knowing what to do.

"Sir, that strange fog is about to reach our first barbed wire, are we going to continue our attack?" A disheveled adjutant reported to the head of the research institute.

Hearing the adjutant's words, the person in charge of the scientific research institute did not answer immediately, but constantly adjusted the focal length of the telescope, trying to see the situation in the dense fog, even if it was just a little bit.

But after trying for a while and finding that it didn't work, the person in charge of the scientific research institute sighed deeply, quickly put down the binoculars and turned to the adjutant and said, "Order!" Immediately let all the city guards in the research institute abandon the first, second, and third barbed wire, and mainly defend our walls, and if they find any enemy, they can open fire at will, without saving ammunition. ”

"In addition, immediately send a team of sappers out to detect whether there are mines on the ground, detect a safe route as soon as possible, and get the backup power in the scientific research institute as soon as possible!"

After saying that, the person in charge of the scientific research institute raised the telescope again, although he still couldn't see anything from it, but now he was extremely anxious in his heart, and only in this way could he calm down......

When the adjutant heard the order of the person in charge, he immediately nodded, and without saying a word, he went down to arrange the task and deploy the defense line.

In this way, under the command of the adjutant, the city guards in the scientific research institute immediately took action, withdrew from the vicinity of the barbed wire fence one after another, concentrated all their forces next to the wall of the scientific research institute, and surrounded the entire scientific research institute like an iron bucket.

Seeing this scene, Lu Jun's heart was unwavering, and he continued to throw dense fog grenades into the distance.

It wasn't until the rising smoke reached a certain size that he summoned twenty triceratops, and then ordered the triceratops to use their size and speed to charge, knocking over the three barbed wire fences in front of them.

The city guards huddled next to the wall only heard a crash and vibration from the smoke in front of them, and before they could figure out what was happening, they saw twenty triceratops rush out of the thick fog, leaving them stunned for a moment.

"Quick! Fire! ”

I don't know who shouted in the crowd, alerting the city guards who were still in a daze, followed by a dense burst of gunfire.

But the city guards were too late to react, and before they could form a net of fire with their bullets, twenty triceratops rushed in front of them and slammed them with their firing guns against the wall behind them......

Although the charging triceratops failed to break through the thick walls of the research institute, they directly killed hundreds of city guards with their sharp horns and flesh in the first few seconds, causing many of the city guards' corpses to stick to the walls.

Under the sudden attack of the triceratops, the city guards defending the eastern wall suffered heavy losses, and their firepower dropped sharply, and the city guards could only call their companions from several other walls to come over to make up for the defense.

But when a large number of city guards rushed over from several other directions, ready to flank the twenty triceratops, the triceratops suddenly disappeared as if they had never appeared again, leaving only the corpses of the city guards all over the ground.

Looking at this incomprehensible scene in front of them, the city guards holding flashlights looked at each other, wondering what was going on.

But before they could come up with the answer to their question, a deafening explosion suddenly erupted from the western wall behind them, and even the ground seemed to "tremble" from the explosion......

"Quick! Defend yourself! Our western wall has been blown open! The enemy is in the west! The city guards' walkie-talkie suddenly sounded the voice of their chief.

And the city guards who heard the order were even more ignorant, because they had been running around like headless flies since just now, and the most terrifying thing was that the enemy had blown their walls open, and they didn't see who the enemy was......
