"Ah Meng, you come."

Nie Bing turned on the external scanning system, scanned his younger brother for a while, and quickly got a set of detailed data. Then remove a set of sets of carats from the material rucksack next to it.

Now that his strength has been stabilized by three stars, coupled with the C+D structure he has mastered, and with the five-star strength of Nie Meng's warriors, it is more than enough to control the C+ structure. This also greatly improves the efficiency of the excavation.

Under the Void Hammer, a group of carat steel turned into a crawler structure, a half-human-high huge mechanical gear, wrapped around the toothy lock chain rail, smooth and calm, imposing.

The plug-in cockpit above builds a simple console, and for veteran gamers like Nie Meng, control is not a problem. Then there is the long robotic arm equipped with a huge bucket, and the bucket here is a full C-level structure built by Nie Bing.

To open up the foundation, C-level five-star is enough.

"Brother, Ah Meng wants to drive an excavator."

Nie Meng looked at this sophisticated and domineering excavator, his eyes lit up, and he was eager to try.

"Well, when I finish installing the power cabin, you'll go and help my brother with his work."

"Yes, brother, I promise to complete the task."

Nie Meng gave a simple salute.

Nie Bing opened the rear cabin cover of the excavator, embedded a group of C+D high-power power core devices in his hand, and welded the wires.

The entire excavation fuselage shook, a huge spherical light shield appeared, and two huge beast phantoms appeared and roared. Five Venus stars twinkle and twinkle around the mask.

"Alright, the steel-toothed beast wire and the mad cow wire. Ah Meng started work! ”

Nie Bing nodded and patted Nie Meng on the shoulder.

"Good!"

Nie Meng, who had been impatient for a long time, jumped onto the excavator and closed the cabin, the power of Yuan Energy on his body exploded, and the machine finally let out the first roar.

Kalala-la-la, the mechanical chain rail crushed the ground, flashing the huge bucket of the five-star C machine, and grabbed into the ground like cutting tofu.

A huge piece of cement was easily excavated, and even the half-broken mechanical exoskeleton was pulled out.

"Good fellow, so powerful!"

Wang Gang and the others, who had already come back and waited on the side, couldn't help but inhale when they looked at the huge engineering beast driven by Nie Meng at this moment.

Not because of the momentum of this machine, but because of its power.

They had just tested the ground with a mechanical pickaxe, and it was as hard as a solid piece of iron, but in front of this excavator, it was as weak as a cake.

"Hey, brothers, it's time to buy and sell."

With a bang, the bucket had just been dumped aside, and Wang Gang and the others controlled the mechanical claws to start picking up the scrap iron inside.

All of them are blushing and thick-necked, just like long-term workers squatting on the dock to grab work, and they have a few words of verbal fighting from time to time.

Nie Bing shook his head from the sidelines.

Unable to get angry, he immediately turned around and went to a distant clearing to prepare for the waste disposal.

According to his design, a circular defensive wall should be built under the roots of the city in the civilian area.

In order to save materials, he will use all C+D structures to build, which will not only improve defense, but also save materials, and reduce the radiation equivalent by half.

After discussing with Wang Gang and Fang Tong, he decided to focus on building an emergency residential area as an emergency shelter.

After all, they are all people who came over eight years ago, and taking precautions is the first priority. Other reconstructions can be built radiating from the shelter to the surroundings little by little.

As he walked, a warm smile slowly appeared on Nie Bing's face.

This is his home, his roots. No matter where he goes, he will never forget the people, the things here, and every interesting thing here.

"At this rate, it won't take more than three months for the inner city walls and emergency shelters to be completed, and even if Yao Dong wants to yin me again, or if the beast tide attacks, this place will be relatively safe. It's the energy consumption in the future, and I have to plan well. ”

……

As the days went by, Nie Bing had already begun to forge the mechanical city wall.

Because of the strong C+D+E structure and the advantages of recyclable waste purification, Nie Bing has saved a lot of money in the price ratio of materials.

The original design of the city wall was 20 meters high, but now he changed it to 30 meters high, and the thickest point reached 15 meters. The internal structure is a variety of defensive wires, as well as sophisticated equipment such as defensive artillery fire and city defense equipment.

It can be said that such a city wall, even if it is a fully armed legion, if it wants to break through without a general-level master, it will cost half of its troops.

Because this is not an ordinary defensive wall, but a five-star top-level defensive wall that integrates C+D perfect weld bead structure and C+C converging power field structure.

According to Nie Bing's prediction, the city wall will be closed in half a month, and then he will be able to build an emergency shelter with all his might.

"Nie Bing, come here, there's something wrong with Nie Meng."

"Ah Meng?"

Nie Bing was startled, looked at Wang Lei who came over, hurriedly dropped the work in his hand, and followed Wang Lei to Nie Meng's excavation site.

"Leizi, what's wrong with Ah Meng?"

Nie Bing said hurriedly.

"Ah Meng is not a big deal, but he is a little frightened. However," Wang Lei pondered for a while and said, "I'm afraid our excavation project has encountered some problems." ”

"Ah Meng is fine, he scared me to death."

Nie Bing glared at Wang Lei and said with a sigh of relief: "What problems did the project encounter?" Don't ramble, say it. ”

Wang Lei said with a dry smile: "We found a rat nest on the garbage heap, which was very deep and couldn't be explored, and a few fierce rats rushed out when Nie Meng was working just now, almost hurting someone." If I hadn't been right in front of me, I'm afraid that everyone around me would be in danger. ”

"Rat's Lair?"

Nie Bingyi frowned, "Aren't all fierce rat beasts ordinary E-class fierce beasts?" What, what's so special? ”

It would not be surprising to say that the civilian area is often infested with fierce beasts, after all, it is very close to the beast jungle. It's normal to stumble into a place where humans live.

"Yes, one of them looks a little scary, and its attack power is not E-class, I feel like it's a D-class beast soldier."

"D-class ferocious rats!"

Nie Bing's heart jumped.

Now that there is a D-class fierce rat as Wang Lei said, then things are a bit bad.

Not because the D-class rats are powerful, but because the D-class rats can control a lot of E-class rats, and now that they have found a direct passage to human habitation, this matter cannot be ambiguous at all.

"Quick, take me to see it!"

……

At one of the largest garbage heaps in the civilian area, several engineering trucks formed a defensive circle and quietly parked in front of a dark cave.

Several veterans led by Wang Gang on the periphery were all squatting behind the bunkers not far away, each holding a weapon and guarding quietly.

"Uncle Wang."

Nie Bing came to the scene and saw the cave in front of him at a glance. There are still obvious traces of a fight around.

"Little soldier, you're here."

And they all gathered around.

Nie Bing looked at Nie Meng on the side, and there was no big problem.

"Don't worry, a few fierce rat beasts should have been vibrated by our construction machinery before they ran out. However, this is also a good thing, so that we can prevent it in advance. Otherwise, they're lurking here, and that's not good. ”

When everyone heard Nie Bing's words, they were all relieved. Unknown enemies are the most terrifying, and it is certainly a good thing to be able to prevent them in advance now.

"Leizi, you go back to get the equipment, Ah Meng, and go on an adventure with my brother in a while."

Nie Bing looked at the surrounding terrain, and while instructing Wang Lei to take the equipment, he temporarily built a defensive cover to cover the cave.

Only the three of them have opened the gene lock here, if they wait for someone to report to investigate, I don't know when, and besides, it's just a fierce rat beast, and the above may not pay attention to it.

So Nie Bing decided to take Nie Meng and Wang Lei down to have a look.
