End of the World: My Items Can Be Upgraded Infinitely.

Chapter 193 Biotechnology, Fleet Enhancement, Countermeasures
At Lin Feng's call, Longyi came over quickly.

When she saw the picture played on the other party's phone and the scarred chariot nearby, she frowned slightly and explained in a low voice:
"This is the variant attack method of the second-order wind-wing insect. It is roughly equivalent to a human attack aircraft, a support-type fighter-bomber."

"Because of the large number of Explosive Bugs mounted on its abdomen, its flying speed is not very fast. It has slowed down to about Mach 1, which is more than 300 meters per second."

"But after this modification, the egg-carrying wind-winged insect poses a huge threat to ground forces!"

"Each second-level wind-wing insect can carry more than a ton of supplies, while the suicide insect, which is not even a first-level Zerg, weighs only five kilograms..."

"So a second-level wind-winged insect can carry 200 suicide insects, and the bombing range is enough to cover 20,000 square meters, an area of ​​three football fields."

"Besides, since the level of the suicide blaster is very low, its hatching and production speed is extremely fast. In simple terms, it is a biological stomach sac, similar to the liquid hydrogen sac in the body of the scarlet beetle. The raw material only needs to be electrolyzed with water, so the energy calorific value generated by the explosion is extremely high. Combined with its own hard and thick armor, it can cause large-scale shrapnel damage."

Speaking of this, I give some advice:

"Although the self-destructing insect is very powerful, its explosive property also makes it extremely fragile after leaving the wind-wing insect. The slightest impact or collision will instantly detonate the hydrogen-oxygen mixture inside."

"So the heavy machine guns on the tanks, and the impact of the fragments produced by their mutual explosions, can detonate it in mid-air."

"But to achieve this, the required firepower density must be higher. A tank that has been around for more than ten years can hardly deal with the continuous bombardment of a group of second-level wind-wing insects."

"The bodies of the suicide bombers are too small, and some of them have grown a few tail wings that can control the direction of their fall, so it is inevitable that some will slip through the net."

"When thousands of suicide bugs come swooping down from all directions, it will be difficult to stop them without sufficient firepower output."

After listening to Long Yi's introduction, everyone looked at each other and fell into deep thought.

Lin Feng took a deep breath:

"Lingyi is right. The fastest solution at the moment is to increase the density of firepower and create a large firepower net in the sky to try not to let them get close."

"So the war is fought with logistics. Now we need to build more tanks! Use the tanks as firing points to block the entire airspace!"

Then he looked at Li Ran:
"Can the second line of defense withstand the suicide bombers?"

Li Ran thought about it and shook his head:

"It's difficult. At the beginning, we didn't consider that the Zerg would have bombing capabilities, so the shooting holes were all parallel to the surface."

"The reinforced concrete poured on the top is only about one meter thick. According to the data Ms. Lin provided, the power of the suicide bomber is about the same as that of an anti-tank gun. Although it is not as terrifying as an anti-tank mine, as long as the speed is fast enough, the impact force generated by the explosion can still penetrate a 50-centimeter concrete wall."

"So if we get hit by two Exploding Bugs in a row in the same direction, we'll definitely be able to penetrate the top fortifications."

"But that's not the worst part..."

Li Ran thought of another possibility:
"If the suicide bomber falls in front of the defense line, it will easily be hit by the defenders in the shooting holes with machine guns or artillery. When it explodes in mid-air, the high-speed fragments and shock waves will pass through the shooting holes and cause a large number of casualties!"

"In fact, from what I just observed, many tanks in the fleet were damaged because their explosive worms were hit by bullets at close range, causing them to explode in mid-air, resulting in the weak roofs being hit by fragments."

The dragonfly nodded slightly, there is no solution to having air superiority.

The Zerg did not use this trick on a large scale when invading other planets, because the alien races on those planets either lived in the ocean or, like the Red Race, had already hollowed out most of the red planet and lived their civilization underground.

But now it seems that this tactic is most useful for humans living on the surface.

But the prerequisite is that the opponent's air force needs to be suppressed, and the Zerg must first gain air superiority.

In fact, as a surface civilization with a rare and favorable living environment like the Blue Planet, humans should vigorously develop aviation technology.

However, due to the fact that civilizations have not yet achieved global unification, they have been plagued by internal strife and internal consumption, as well as the fact that their development time is too short, their aerospace power is very weak.

Before the Zerg invasion, looking around the world, there were only a few major countries that had the ability to independently produce fighter jets, and the number of fighter jets that could be used for combat was only more than 20,000.

Although it sounds like a lot, don’t forget that there are more than a thousand Zerg Queens alone, and the number of Green-winged Zergs and Wind-winged Zergs combined is more than a hundred thousand?

Therefore, even though the Zerg has a long-term weakness in aerospace power, they can still suppress the humans on Blue Planet.

Only because the Federation was the world's most powerful country, with nearly 5,000 fighter planes, did the Coastal Queen Mother dare not mobilize large-scale aerial bombardment at the beginning of the war.

Looking at it now...

If you want to deal with the harassment of the green-winged insects, you can still use ground-based air defense forces, but to deal with the high-altitude attacks of the wind-winged insects, there is only one way:
Kill it from the air, and send out flying units with the same speed as it, close to Mach 2 or 3.

However, today the satellites of humans on Blue Planet are basically scrapped, and ground radars are also affected by electromagnetic pulses, making it impossible for surface-to-air hypersonic missiles to track and lock onto targets.

In addition, the wind-wing insect has the same high maneuverability as the blue-wing insect. It can stop flying instantly, hover and make a 180-degree turn. In terms of flying performance, it far exceeds all large fighter jets developed by humans.

So it seems that the only solution is to form a group of soldiers with flying capabilities.

When Long Yi was thinking about this, Lin Feng beside him obviously also realized that relying solely on ground air defense to resist bombing was only a passive defense, and the initiative was still in the hands of the Queen Mother.

The Queen Mother of Haicheng can consume human logistical resources at a very low cost and disperse their sniping firepower, thereby providing containment and cover for the real main ground attack.

After thinking about it, Lin Feng said:

"If the second line of defense can't hold up, then we will reduce the number of defenders inside and focus all our firepower on air defense. We will no longer be responsible for stopping the insect swarm."

"Because only ten tanks are needed to effectively annihilate tens of thousands of black-spine insects. With the firepower support of the dreadnoughts, even if we face hundreds or thousands of second-level tiger-spine insects, we can easily suppress them."

"We have an absolute advantage on the ground battlefield, so we must make use of the fleet's mobility to push the battle outbreak point forward and strive to gain more depth."

"That way, we don't have to worry about the other party using a second-level pulse scorpion to attack the second line of defense from a distance."

About ten kilometers behind the second line of defense is the shore of East Taihu Lake. The defenders of Wucheng are actually fighting a battle with their backs against the river, so naturally they have to muster the courage to burn their boats.

As he spoke, Lin Feng pointed to the five heavy trucks behind him that had already finished unloading. Next to them was a mountain of more than 500 tons of refined steel:
"I can probably synthesize more than 40 tanks now, which adds up to 60. This way, we can carry at least 1,200 people. We will divide them into six teams and surround the dreadnought. The two teams in the front will be responsible for attacking the ground insect swarm, while the left and right flanks will provide fire support and air defense. The two teams behind the dreadnought will be responsible for defending against attacks from suicide insects in the air."

After saying that, Lin Feng controlled the dreadnought to turn the bow and sailed to the vicinity of the pile of fine steel. He opened the collector on the bow to clean the battlefield and swallowed more than 500 tons of fine steel into the storage space.

After the invasion, the speed of the dreadnought slowed down a lot. With Lin Feng's remote control, its stern hatch opened wide, and a number of brand new lv19 flying wing tanks slowly drove out of it.

Although the battle this afternoon was fierce, the fleet that suffered the attack did not gain nothing. In addition to devouring a large number of black-backed insect corpses, some green-winged insects that came to reconnaissance were also directly shot down by Chen Yanyan and the sharp-eyed soldiers.

In the end, a total of seventy or eighty green-winged insect corpses were collected.

It is enough to produce more than 40 flying wing tanks at present, and to cover the consumption of fusion and replication.

As the chariots drove out of the rear hatch of the dreadnought battleship and docked in the station square, it gave everyone the illusion that a whale was giving birth.

It seems that this dreadnought battleship also has the ability to automatically produce and synthesize.

While everyone was stunned, Lin Feng was checking the properties of this batch of battlefield replicas:
「LV19 Winged Tank—Replica, Red Quality」

"Cannot be upgraded, defense 150, damage 130, average speed 150km, range 1000km"

"Additional attributes: biological armor (defense +50), armor-piercing head (damage +20),

Unlimited firepower: 40 heavy machine guns, damage , unlimited bullets
Multiple artillery: Load five lv19 shotguns, damage 190, range 5km, spare ammunition 5000, bullet recovery 1/1s
Ground effect flight: speed increased by 150km/h, can adapt to complex water terrain, fuel consumption increased by 100%, and cruising range reduced by half"

"Note: As a replica, it cannot be upgraded, but it can obtain energy replenishment from the original Land Cruiser for endurance driving, spare ammunition and damage repair consumption."

This replica has more shared attributes than the original winged vehicle.

Spare ammunition and automatic repair of damage can all be obtained from the land-faring properties of the dreadnought, which uses energy calcined from Zerg corpses.

This is of great significance to extending the combat capability of the tank.

In Lin Feng's opinion, these special changes...

Perhaps it is because they were produced directly from the body of the dreadnought, and there has been a strong connection between the two since the birth of the replica tank.

It is precisely because of this that Lin Feng can remotely control the lv29 flying wing tank directly through the lv19 dreadnought battleship.

Chen Yanyan, who was standing behind Lin Feng, also obviously noticed this magical point.

In the end, more than 500 tons of fine steel, as well as thousands of black-backed insects and dozens of green-winged insects were consumed to produce forty-five flying wing chariots.

Together with the remaining fifteen tanks, there were sixty in total. This force, coupled with the dreadnoughts, was enough to easily deal with the impact of the Sea City Zerg.

In addition, Lin Feng used the remaining dozens of tons of fine steel to synthesize more than 19 level shotguns to arm the soldiers who followed him.

Lin Feng immediately called Li Ran:

"Select a group of late-stage first-order awakeners, about three hundred of them will do, and equip each of them with a shotgun. Then they will follow me to carry out another important plan."

Li Ran nodded, called the captain of the combat camp, and began to screen and recruit.

At this point, anyone with a discerning eye can see that following leader Lin Feng will definitely bring the greatest benefits, and the risks are controllable. The next best option is to join the fleet and become a gunner on a chariot. Although this has certain risks, it is easy to kill a large number of black-backed insects and advance to the peak of the first level, so the gains are also considerable.

Excluding the 300 temporary guards of the leader and the 1,200 members of the fleet, the remaining 3,500 soldiers can only stay in the second line of defense, or be responsible for the later command in the camp and serve as support substitute teams.

Not only is there a risk of being bombed, but there is no benefit of insecticide upgrade at all...

Therefore, those who had good vision immediately signed up to join the leader's direct team, and the rest who were not strong enough also actively went to the fleet to apply to become a gunner.

Taking advantage of the gap in personnel arrangements and mobilizations, Lin Feng repaired the fifteen damaged tanks that were returned from the battlefield one by one.

Then, he took out the remaining dozen pairs of blue-winged insect corpses in the storage space from the rear hatch of the dreadnought.

Now, at most a dozen level 19 red and black flying armors can be made from them, but the lifespan of each set is only about ten minutes.

Therefore, judging from the maximum flight speed, altitude, and duration, a flying soldier wearing the Red Black Flying Armor is simply unable to carry out the mission of attacking the second-order wind-wing insects at an altitude of thousands of meters.

This is also one of the obvious shortcomings of the armor.

Although it retains the Zerg's solid defense and flying ability, it is difficult to adapt as flexibly as the Zerg because it has no matching flesh support supply.

After all, one is a burden that you wear on your body, while the other is a natural part of your body.

The flight performance issues we are facing now are a concentrated reflection of this aspect.

When the green-winged insect's membranous wings grow on its body, it can use them at will as long as it has enough energy in its body. It can continue flying for several hours without worrying about overheating due to flapping of the membranous wings.

Because the base of the membranous wings is connected to the blood circulation of the entire body, and the whole body is blown by the wind during flight, which naturally dissipates heat.

Unlike flying armor, it can only last for ten minutes due to overheating problems at the roots of the membrane wings.

At this time, Lin Feng took out the body of the green-winged insect, actually looking for a way to solve this problem.

He turned his attention to the eight second-level regiments that were gathering and reorganizing.

But according to the division of genetic warriors and ordinary awakeners, the regiment is now divided into four ordinary regiments, with 80 members and five leaders, and three genetic warrior regiments, with 70 members and three leaders.

So with Lin Feng's approval, Liu Yi became the commander-in-chief of the four ordinary regiments.

They are also the main force that follows Lin Feng to carry out the decapitation plan this time.

As for the Gene Corps composed of Gene Warriors, Lin Feng was ready to give them a task that was both difficult and easy:

Form an aerospace group to specifically deal with the high-altitude suicide insect bombings used by the Queen of Haicheng!
Night had fallen by now.

The number of patrol sentries in the entire camp has increased tenfold, and everyone is on high alert, ready for action!

Under Lin Feng's order, Shen Jie brought 72 genetic warriors to the room where the green-winged insect corpses were stored, and then dealt with the insect corpses in front of everyone.

Pull off the membranous wings on their backs and cut them off along with the thick muscle ligaments at the base.

Then he started eating with big mouthfuls.

While eating, he said:
"Since you have my cell genes in your bodies, you can naturally activate the ability to fly. The blue-winged insects and the black-spine insects actually have the same origin..."

"Give it a try, it should be able to activate that part of the gene!"

After saying that, he threw the other half of the membrane wing in his hand to the leader of a genetic regiment in front of him.

After the other party took it, he swallowed unconsciously.

In the quiet room, in addition to the crisp chewing sound coming from Shen Jie's mouth, there was also a swallowing sound.
