(Brothers, you are so powerful! Yesterday, they actually rushed to the top 30 of the total list and ranked fourth! I was really shocked. It seemed that the position of asking for votes should be rolling all over the ground, so I'm going to roll a few times!

Hehe, just kidding.

To express our gratitude, there will be an outbreak in two days. Please support me as always. Morningstar thanks! See which one we can reach the monthly ticket list this month!

You guys, killing gods and destroying Buddhas is about to come!)

The end of the world.

After more than half a month of efforts, the entire heterogeneous nests on the west side of Wanghai City have been basically removed. In addition, NAC soldiers also deployed eleven checkpoints along the Huangpu River, blocking all bridges from Xicheng District to Dongcheng District to prevent the spread of heterogeneous species from the East District to the West District.

Now the entire western area, whether it is the surface or the sewer, has been removed by the mercenaries and the army of NAC. Although mutant cockroaches and rats are difficult to eradicate, zombies, meat mountains and even the more aggressive heterogeneous species such as Dead Claws are basically invisible in the entire western area. Under the force of NAC, the large and small survivor groups in the western area of ​​Wanghai City have surrendered to the rule of NAC.

The mercenary groups and plunderers were originally unclear, and they also moved from good to good, and they moved out. After witnessing the overwhelming rain of rockets, they really couldn't have the idea of ​​resisting. Nac had already used its force to declare its dominance over Wanghai City.

Even Liu Ding Town, who was originally on par with the Sixth Block, seemed a little too short of watching when facing the huge NAC.

It would be better to say that when they saw the bombardment of the Staff of God on the city center, they were completely convinced. They did not know that NAC was fighting the Supreme, but only learned that they had plans to clear out the alien nests in the city center. So they mistakenly believed that the tungsten rod bullet was fired by NAC people...

In addition to establishing dominance, NAC also sent engineers wearing nuclear protective suits to the city center to clean up the radioactive sources piled up in the city center.

The radioactive substances that are difficult to remove are contained in the lead bucket and thrown into the deep pit in the city center where the tungsten rod is blasted out. The lead-containing cement is poured on for landfill. The light radiation area is sprayed with radiation cleaning liquid. I believe that it will not take long before the gamma value in the entire city center will return to normal levels.

In addition, there are exploration teams sent to the Atomic Energy Company, Research Center, and Industrial Base Ruins to search for pre-war technology. All collected technical documents will be sent to Camp No. 27 for summary and classification. The city center "protected" by radiation is like a treasure that has not been ruined. Many technical data hidden in underground bunkers are well preserved and have high value. More than a thousand scientists in Camp No. 27 were immediately busy.

The Huangpu River crossing Wanghai City is like a Berlin Wall, with the orderly and stable NAC occupied area on the left, and the right is a chaotic "reserve land".

With the end of the alien tide, the survivor group in the East District has returned from large survivor bases such as Liuding Town to their homes built on the ruins and started to live again. However, after witnessing the gap between the two sides of the Huangpu River, there was no need for too much publicity. Survivors who yearned for the safety and stability of the Xicheng District migrated to the west bank of the Huangpu River with their families.

The NAC checkpoints occupying the Huangpu River Bridge did not stop their migration, but all survivors who migrated from the East City to the NAC ruling area must hand over dangerous goods such as nuclear grenades, mini nuclear bombs and other dangerous goods in accordance with regulations. The policy of denuclearization has been advanced from the Sixth Block and spread to the entire NAC ruling area.

At this moment, Wanghai Airport.

More than a dozen construction vehicles were working on the runways driven by the airport, repairing the broken airplane runway that was bombed during the war. The repair work was tendered by NAC. The Metal Shell Chamber of Commerce, the largest builder in the sixth block, was undertaken by the Second Corps, and the Second Corps was responsible for ensuring the safety of the construction site.

This pre-war civil airport has been requisitioned by NAC. As the first military airport of NAC, it is classified as managed by Camp No. 27, which is close to the airport. At this moment, a flat shuttle-shaped fighter is lying quietly in the apron of the airport, which looks like a seagull, named Aurora-20.

At this moment, Jiang Chen was standing in front of the apron and under the leadership of Fang Weixian, visiting this new weapon developed by Shelter No. 27.

"Aurora-20, a fixed-wing fighter, can take off through two modes: vertical take-off and landing and runway. The belly of the aircraft can be equipped with 2 short-range air-to-air missiles, and 4 medium- and long-range air-to-ground missiles. The nose is equipped with a 10mm cannon. According to your requirements, the firepower is absolutely reliable!" Fang Wei first patted the nose and grinned at Jiang Chen.

Including Huhunting ii and Yunzhi-51, the cutting-edge military products of the entire NAC are basically the hands of the technical team led by Fang Weixian.

He nodded with praise, and Jiang Chen looked at the powerful fighter.

“What about concealment and speed?”

Concealment and speed are the life of fighter jets. The thickness of the armor does not make much sense at altitudes. No matter how advanced the fighter jet is, it is difficult for them to withstand the direct attack of two missiles.

"The aircraft shell is coated with radar signal attenuation coating. On most radars, the area displayed is only equivalent to a sparrow. The radar signal detection system at the bottom of the aircraft can reversely track the coordinates of the ground radar base station. As for the speed, the maximum cruise speed can reach Mach 4.5." Fang Weixian's mouth curled a smug smile.

Jiang Chen was also very satisfied with this number.

The maximum speed of Mach 4.5 has exceeded the Mach 3.2 record set by the MiG25 high-altitude high-speed interceptor in the current world, and has approached the speed limit that fighters in the atmosphere can reach.

Of course, when approaching combat, the maximum speed cannot be used for combat. Otherwise, not to mention Mach 4.5, even Mach 2, the acceleration of the aircraft will make the pilot faint.

In addition, according to Fang Weijie's introduction, this "Aurora-20" fighter can have a combat radius of 3,100 kilometers without tanker support, which is far beyond the record of 2,177 kilometers set by the US F22. On the one hand, it is because the new titanium alloy material used by the aircraft makes the aircraft much lighter than the 21st century fighter jets, and on the other hand, it is because the engines and synthetic fuels used by the aircraft are better than those of the 21st century.

"From the engine to the fire control system, it is all the military technology of PAC. From the aircraft's landing gear to the air-to-air missiles, it is all made of 3D printing technology."

"How feasible is the industrial production?" Jiang Chen asked.

The cost of 3D printing is high, which will waste a lot of materials and energy. The cost of 3D printing to produce a fighter is about three times that of a fighter on an industrial production line. Although the NAC is rich and powerful, if all cutting-edge weapons rely on 3D printing technology, Jiang Chen will still feel a little distressed when the money is burned.

"It's very difficult, the engine's heat-resistant material is difficult to achieve with the industrial level of the sixth block." Fang Weixian shook his head.

Jiang Chen thought for a moment and said.

"Transfer some of the production materials for simple process parts to the military factory in the Sixth Block and outsource these parts to them as much as possible. In this way, the cost should be much lower than 3D printing. And it can also shorten the production cycle. Do you think it is feasible?"

Fang Wei first pinched his chin and started to think hard.

"Are the parts with simple technology? Strictly speaking, no part has a simple production process..."

Jiang Chen shook his head and said with a smile.

"What I mean by simple technology does not mean the difficulty of producing according to the production process we know. It is technical feasibility. Don't underestimate the creativity of wasteland people. As long as we offer the right price and can be realized technically, they may be able to develop a production process that is more cost-saving than us."

Fang Weixian was obviously not convinced by Jiang Chen's statement. After all, he came from a refuge and was also an elite class before the war. He really didn't believe that those survivors who dressed like "beggars" had the ability to solve the production problems of fighter parts.

But due to the status gap, he did not show his disdain for wasteland survivors.

Seeing that Fang Wei didn't say anything at first, Jiang Chen probably guessed what he was thinking. But he just smiled and didn't say much about this issue.

Fang Weixian is very arrogant. But this arrogance is not arrogance for no reason, but arising from his rigorous technical attitude.

"Science and technology are two different things. The former determines the development space of the latter, and the latter determines the practical value of the former. Being able to survive in the cruel end of the world has proved the creativity of survivors."

"But you can't expect a group of refugees to do the job of technicians... Well, if you insist. I think... screws, wings, canopies, ejection seats, operating interface shells and so on. About 60% of the basic parts are not very technically difficult." Fang Weijie sighed like giving up.

"Very good." Jiang Chen nodded and patted the technician's shoulder with satisfaction. "You can list these parts in detail and hand them over to Xu Lu. The rest of the parts are still produced by 3D printers."

"I understand." Fang Weijie nodded slightly.

They are only responsible for research and development, and to build the first prototype, providing drawings and production details. As for the specific production matters, the military factory of the Fish Bone Base will be responsible for it, and no scientists such as them need to worry too much.

"About the next scientific research project," Jiang Chen paused. Looking at Fang Weijie and said seriously, "I hope you will develop an airship that can stay airborne for a long time, with armor protection capabilities and basic firepower."

"Airship? Armored protection capability?" Fang Weijie was stunned for a moment and frowned slightly, "Are you still made of steel?"

"Is it technically difficult to achieve?" Jiang Chen asked when he saw Fang Weijie's embarrassed expression.

"No, it is not very difficult to achieve technically, but... I have never heard of a weapon like an airship." Fang Weijie said helplessly.

He had never heard of what he said, so he had to be before the war. Not to mention before the war, airships, which had poor mobility and large targets, were eliminated as early as the beginning of World War II. Although it was not difficult to build a steel airship with 22nd century technology, Fang Weijie was deeply doubted how cost-effective such a weapon could be.

So he said tactfully that he had never heard of this weapon before and hoped that Jiang Chen would change his mind.

"It's okay, it didn't exist before the war. Just use the pre-war technology to build one from beginning to end." However, Jiang Chen did not change his mind.

"But the steel, titanium alloy, copper, and aluminum needed to build such an aerial fortress will be astronomical. From the perspective of cost-effectiveness, is this thing really meaningful?" Fang Weijie questioned.

"Of course it makes sense." Jiang Chen said with a smile.

As he said that, he looked into the sky outside the airport.

It was clear, but further afield, it was still cloudy.

Looking along Jiang Chen's gaze, he asked without understanding Jiang Chen's meaning.

“What is it?”
