"They can't get out now, they must be panicked. It is a good time for us to launch an offensive, but we can't directly rush out because the opponent’s firepower is very fierce. Under the cover of darkness, we will surely be able to make a single blow." The Lu Army said his thoughts while handing out grenades.

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

"It will take about ten minutes for the wood to come back. Let's attack first. Time doesn't wait for people. Now the attack has the best effect." Lu Jun affirmed his thoughts, and his eyes also revealed determination.

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

After there was no problem, the Lu Army took the women forward for more than two hundred meters, and then threw the first thick fog grenade in his hand, allowing the thick white fog to cover their way forward.

The Nguyen sisters and the girl in red also learn from each other, throwing out two dense fog grenades every time they walk more than 20 meters, using this method to move forward slowly.

The defense forces standing around the scientific research institute also noticed the thick fog rising not far away, but due to their vision, they didn't know how the thick fog was produced.

Some more resourceful defense forces also used high-intensity flashlights to take pictures in the direction of the dense fog, but they could not find any abnormalities.

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

Upon hearing the orders of the person in charge, the city guards naturally followed suit, using their own firearms and various heavy weapons to form a firepower net, covering the entire range of dense fog.

The Lu Army in the thick fog saw that the city guard opened fire, and did not panic at all, because he knew that the people in the scientific research institute could not see him, and most of them were shooting randomly, so he just slightly propped up a particle shield to protect it. The girls did not consume much brain power.

In this way, despite the fierce firepower of the City Guards, there were constant rockets and bullets flying past the road army and others, but very few of them could really hit the middle road army.

Even if a bullet happened to be shot at the location of the road army and others, they still have a particle shield as protection, so they will not be injured at all.

Seeing that the city guards had spent a lot of bullets but failed to achieve the desired effect, the Lu Army secretly rejoiced in his heart, and continued to throw the dense fog grenade in his hand and moved forward slowly.

After a round of ammunition, the people of the city guard found that the thick fog was still spreading, and was not affected at all. Instead, they were getting closer and closer. They suddenly panicked and didn't know what to do.

"Sir, that strange thick fog is about to reach our first barbed wire fence, shall we continue to 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.

However, after trying for a while and found that it was invalid, the person in charge of the scientific research institute sighed deeply, quickly put down the telescope and turned his head to the adjutant: "Order! Let all the city guards in the scientific research institute abandon the first and the second. Three barbed wire fences mainly guard our fence. If you find any enemy, you can open fire at will without saving ammunition."

"In addition, immediately send a team of engineers out to detect whether there are mines on the ground, and detect a safe route as soon as possible, and the backup power in the scientific research institute should be fixed for me as quickly as possible!"

After speaking, the person in charge of the scientific research institute raised the telescope again. Although he still couldn't see anything from it, he is extremely anxious in his heart now. Only in this way can he calm down...

The adjutant nodded immediately when he heard the command from the person in charge, and went down to arrange a mission to deploy the line of defense without saying a word.

In this way, under the command of the adjutant, the city guards in the scientific research institute immediately took action and evacuated from the barbed wire fences one after another, concentrating all their forces on the walls of the scientific research institute, surrounding the entire scientific research institute like an iron bucket.

Seeing this scene, the road army did not feel any waves, and continued to throw thick fog grenades into the distance.

He called out 20 triceratops until the rising smoke reached a certain size, and then ordered the triceratops to use their size and speed to charge, and directly knocked over the three barbed wire fences in front.

The city guards who were shrunk by the wall only heard a shock and vibration in the smoke ahead. Before they had time to figure out what happened, they saw twenty triceratops rushing out of the thick fog. They were stunned for an instant.

"Quick! Fire!"

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

But the reaction of the city guards was too late. Before the bullets they shot formed a firepower net, twenty triceratops crashed in front of them and slammed them with the firearms on the back wall. ...

Although the charging triceratops failed to break through the thick walls of the scientific research institute, they directly killed hundreds of city guards with sharp horns and flesh in just a few seconds, resulting in the return of many city guards’ bodies. Stick to the fence.

Under the sudden attack of the Triceratops, the city guards defending by the east wall suffered heavy losses and their firepower dropped sharply. The city guards could only call their companions from the other walls to make up for the defense.

But when a large number of city guards rushed over from several other directions, they were ready to pinch the twenty triceratops. The triceratops suddenly disappeared like molecular disassembly, as if they never appeared again, leaving only the city full of ground. The body of the guard.

Seeing this incomprehensible scene in front of them, the city guards who raised their torches looked at each other, wanting to know what was going on.

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

"Quick! Come back to defense! Our western wall was blown up! The enemy is on the west!" The voice of their leader suddenly sounded from the walkie-talkie of the city guard.

And the city guards who heard the order didn’t understand all this, because they have been running around like headless flies from just now. The most terrifying thing is that the enemy has blown up their walls. None of them saw who the enemy was...

However, it is obviously not time to think too much now, the full-bellied city guards can only follow the command of the chief and run back with weapons.

In fact, all of this was a temporary plan made by the Lu Army. He just let the Triceratops pretend to attack the east side of the wall to attract the attention of the city guards, but he and Ruan Bing and others took advantage of the chaos to touch the west side of the wall. went.
