But the 20,000 city guards had just surrounded the scientific research institute when they encountered a big problem, that is, they found that the scientific research institute was surrounded by landmines.

Although they were numerous and armed with guns, the induction mines in the ground still made them suffer enough.

Anyway, the situation now is that no matter which angle they are advancing, they will encounter landmines and be blown up on their backs. ”

Although they had paid great attention, the casualties were still very large, and before the enemy in the scientific research institute could see it, hundreds of people were injured on their side, and their morale was very low......

Fortunately, the city guards brought three tanks with them, and when they found that ordinary vehicles could not pass through the minefield, they immediately let the tanks clear the way, trying to use the tanks to destroy the mines in the minefield.

This method is also very effective, as the tank advances, the induction mines are constantly detonated, but the power of their explosion cannot shake the tank's armor, causing the tank to "grind" a safe passage from the minefield.

Just as the city guards were about to continue using this method to widen the passage, the three tanks suddenly stopped advancing.

This is due to the fact that although the armor of the tanks can withstand the induction mines, their tracks do not have such defensive power, and after the "baptism" of many mines, these tracks are finally disconnected overwhelmingly.

Seeing this, the city guards had a lot of headaches, and now it was too late to repair the tracks or remobilize the tanks, so they could only walk in a long line through the narrow passage.

And Ah Ke and the girl in red, who were guarding the hole in the wall of the scientific research institute, saw that the city guards were about to enter, and immediately hid behind the ankylosaurus and kept firing, trying to delay the advance of the city guards in this way.

But at the same time, their position was also exposed, and the fierce fire of the city guards was suppressed at once, so that they could not even raise their heads, and the ankylosaurus and triceratops were also in danger of being injured.

Seeing this, Ah Ke and the girl in red could only take the dinosaurs and were forced to retreat to the cave entrance of the scientific research institute, ready to rely on the building to hold on, and at the same time kept praying that the road army could come out quickly, otherwise they would not be able to hold it......

At this time, Lu Jun had just come out of the underground facilities of the scientific research institute, and he didn't know the specific situation on Ake's side, but when he heard the gunshots outside, he could roughly guess that the city guards were coming.

"Boss Lu, I just took a look, and the outside has been completely surrounded by the city guards, and Ah Ke and the others are resisting with all their might." As soon as Da Xiong saw Lu Jun coming out, he immediately reported.

Hearing Da Xiong's words, Lu Jun nodded silently, letting Abelilong walk in the front, and then waved his hand, signaling everyone to follow, ready to support Ake and the girl in red.

The dozen or so researchers who walked at the back looked at the huge Abelisaurus in front of them, almost frightened to move, they had not seen this creature up close.

But Shaqiri saw Lu Jun walking in this direction, and felt very strange, because there was no exit from the scientific research institute there, so he immediately mustered up the courage to remind Lu Jun: "Are we going wrong?" I know the internal route of the research institute, do you want me to lead the way? ”

Hearing Shaqiri's words, Lu Jun shook his head directly and said, "The other exits of the scientific research institute are blocked by the alloy gate, and only one broken wall can let us out. ”

After saying that, Lu Jun didn't explain anymore, and walked forward without looking back, while Mu and Shaqiri and the others followed closely behind him.

After two minutes of rapid advancement, the Lu Jun group finally came to the place where Ah Ke and the girl in red were.

The first thing that caught my eye was the black and oppressive figures outside the research institute, the ferocious fire of the city guards, and the rockets with tail flames that were about to collapse the surrounding walls.

Although Ake and the girl in red were fighting hard, using their own strength to hold the line of defense at the entrance of the cave, they were only two people after all, and they could not stand alone.

Under the fierce offensive, from time to time, a group of city guards will rush into the scientific research institute, fortunately, there are many dinosaurs left by the road army in the scientific research institute, otherwise the defense line at the entrance of the cave is estimated to have fallen......

Seeing this, the Lu Jun immediately asked Ake and the girl in red to retreat, and then asked Aberlisaurus to use its clone as a clone to attract the attention of the city guards.

After the firepower of the city guards was attracted by the "fake" dinosaurs, the road army immediately took out a large number of smoke grenades and threw them outside.

Although Mu and the others didn't know what Lu Jun's next plan was, they also helped throw smoke grenades on the side until the outside was covered in white smoke.

"Okay, you will rush out with me later, I will use my abilities to protect you, no matter what happens, don't fall behind, otherwise I won't be able to save you." Lu Jun looked at everyone on the field with a serious face.

After saying that, the road army let the triceratops rush out first, followed by the Abelisaurus, and finally the ankylosaurus, and he wanted to let these dinosaurs go out to distract the city defense army.

When the people on the field heard Lu Jun's advice, they also nodded one after another, preparing for the next breakthrough.

Shaqiri and the researchers, despite their confusion about Lu Jun's words, chose to trust Lu Jun unconditionally, after all, they had no other way out.

Seeing that the dinosaurs had gone out and the people around him were ready, the Lu Jun no longer hesitated, and rushed outside with the Death Slaughter 8000 type, and everyone followed closely behind him, and the target was the place where the Lu Jun placed the portal.

The city guards looked at the smoke that suddenly rose around the research institute and wondered what was going on inside, but before they could figure it out, they saw dinosaurs rushing towards them.

"Not good! They want to run! Hurry up! Be sure to stop them! One of the captains of the city guards raised the walkie-talkie and shouted, he could roughly guess what Lu Jun and the others wanted to do.

The city guards who had just finished dealing with the Abelisaurus clone heard their captain's order, and they all aimed their guns at the thick smoke, blocking almost any possible position of the road army and others.

Hearing the gunshots in the distance and feeling the oncoming bullets, the Lu army did not panic, and immediately mobilized his brain to prop up a huge particle shield to protect him and the people behind him, and then continued to rush towards the destination with the help of the cover of smoke.

At the same time as the city guards attacked, the dinosaurs sent out by the road army were not idle, and rushed to the place where the city defense army had the most, constantly overturning the vehicles of the city defense army, and covering the retreat of the road army and others at the risk of injury......
