The overwhelming sand monsters, one after another, rushed towards the city wall that was less than 70 centimeters high and one and a half meters wide without fear of death. Even though most of Qiu Feng stayed within the city wall, his fatigue level was still as high as 60

Point, it is estimated that those auxiliary combat logistics personnel and the four indigenous people with S-level qualifications will not have an easy time either.

Facing the sand monsters all over the mountains and plains, Qiu Feng was already a little numb. Xiang Xixi was still very excited in the sky, driving a helicopter to patrol the 1,600 square kilometers of the sky, suppressing it with firepower.

"No! Fatty, my fatigue level is already 65. Prepare bombs and grenades. The first line of defense is almost overwhelmed. The monsters are already within 150 meters of the edge of the city wall. The next wave will definitely break through the security cordon.

"Qiu Feng shouted.

Xiang Xixi said: "Oh my god, idol brother, although I am not happy enough, but it is important to defend the base. Just wait a moment. I will go to the second line of defense to replace four D-level combat robots, and then start the helicopter.

Come to you.

The system is so disrespectful that it doesn't even allow you to breathe. The players are fine and there are always ways to recover their fatigue, but the aborigines in the base are in dire straits.

The system shows that we still need to defend for eight hours. We have at least successfully blocked the eighth wave of monsters outside the city wall. The strength of the first line of defense has far exceeded our imagination. Now I dare to conclude: We will defend this time

It worked."

"You have a good attitude, but you can't be careless. I estimate that the D-class battle robots will definitely suffer a certain degree of wear and tear. Otherwise, if you drive a double-decker passenger car, we will automatically abandon the city wall when the next wave of brushes begins. . Some D-class battle robots

We also need to bring back the second line of defense. Otherwise, I'm worried that although the defense circle is shrinking, the firepower will not be enough."

"I will make the arrangements. You can fight with peace of mind and contain the next wave of monsters a little. Those D-class battle robots that are almost scrapped should not be too stingy and stay on the edge of the city wall to fight until the last moment.

Oh, I go, I feel very sad. This unfinished city wall cost me tens of thousands of building materials at least. It was ravaged by monsters like this. I don’t know how many building materials can be recycled in the end.

When we go back to repair it, we must reduce the scope of the city wall..."

…

Soon, Qiu Feng was driving a helicopter, with four D-class combat robots and ten combat logistics auxiliary personnel hovering in the sky. Xiang Xixi looked at the double-decker passenger cars, flying desperately around the inner circle of the city wall.

.

In order to evacuate some D-class combat robots... Qiu Feng could only start throwing bombs and grenades in circles ten kilometers away from the city wall to delay the monsters from reaching the city wall.

…

"Come on, idol brother, each of the two Hakka buildings has ten D-level combat robots, ten combat logistics auxiliary personnel, and fifty residents with E-level qualifications or below, which can last a lot of time.

The second line of defense was in the safe zone, so the residents made a simple defense, with a total of thirty-two D-class combat robots, 4 S-class combat robots, 110 soldiers, 4 S-class aborigines, and 79 combat logistics personnel.

Auxiliary personnel, we are determined to end this defensive battle beyond the second line of defense.

Now that everyone has evacuated, you can implement the battle robot suicide tactic."

"There is nothing we can do about the pain. More than half of the D-class combat robots have been lost. I hope there will be no battle losses among residents and soldiers." Qiu Feng said heartbrokenly. Although giving up the defense of the city wall means that tens of thousands of building materials used to build the city wall in the early days were wasted.

It is even possible to lose the Hakka enclosure building, but compared to the victory in the final base upgrade town defense battle, as well as the S-level qualified aborigines and S-level combat robots, Qiu Feng also had to cut off his strength.

Countless bombs and grenades poured out from the helicopter. There were always two D-class combat robots pouring ammunition downwards from the helicopter, as if metal warheads were raining down from the sky above the base defense battle.

The more than 30 combat robots left on the inside of the city wall were raining bullets like crazy, and the barrels of their guns turned red without caring. Once a sand monster broke through the city wall that was less than 70 centimeters high, these combat robots would automatically start to self-destruct.

program, the sand monsters were blown up in all directions.

Fortunately, it took a full wave of sand monsters to break through the city wall.

Once the subsequent sand monsters rush into the inner side of the city wall, a large part of them will surround the Hakka enclosure building and attack. The Hakka enclosure building is originally a defensive dwelling house. The outer wall is twelve meters high and is round. The sand monsters are very uncomfortable.

It was so powerful, and there were D-class combat robots inside that poured out ammunition, a primitive defense method for the residents. As a result, the number of sand monsters gathered around the Hakka building was no less than the number of sand monsters attacking the second layer of defense.

By retreating to the second line of defense, the defense circle suddenly shrank to 16 square kilometers, and the defensive strength basically remained unchanged, so it was easier to deal with it.

Qiu Feng didn't even need to go to the second line of defense. He just targeted the two Hakka buildings to eliminate the sand monsters that posed the greatest threat to the Hakka buildings. Of course, the original Star Master image was still the first target to attack.

There are still three hours left before the end of the defensive battle, but it seems that all the sand monsters have been killed. .It is no longer refreshed, and the helicopter has been handed back to Xiang Xixi before the first batch of monsters are refreshed.

Qiu Feng calculated silently and knew that the defensive battle was over and fifteen waves of monsters had been spawned, but he still said in the legion channel: "Fat man, there have been no monster spawns for 15 minutes. Could it be that our defensive battle was successful?"

The corpses of monsters on the ground have not been refreshed, otherwise I will go pick up the corpses first, and you can help me keep an eye on them from the sky?"

"Well, let's go. We must not take it lightly before the system sends a prompt. Fortunately, the base defense battle did not say that the defense failed if the commander died.

Oh, let me go, I shouldn’t have changed that just now, picking up corpses, it’s only appropriate to leave this matter to me, the only heir to the European Emperor..."

After Qiu Feng walked from the battlefield to the logistics supply machine three times in a row... Xiang Xixi finally couldn't help it. He parked the helicopter next to the fruit farm and quickly joined the team of picking up the corpses.

There was still an hour left until the end of the base upgrade defense system prompt, and there had been no monster spawning for more than two hours. Even Qiu Wei, Qiu Yue, Qiu Youyu and Qiu Wujiu couldn't sit still, and they all

Joining the team that cleans the battlefield, Qiu Feng had to restrict the aborigines from sweeping corpses of monsters over five meters in size, because the aborigines did not use props to sweep corpses and could only exchange corpses for tokens. Basically, monsters over five meters in size were

Elites or mutants.
