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

Seeing the fierce battle, Lin Feng immediately controlled the fourth-level battleship and rushed to the battlefield.

Lin Feng drooled at the sight of one small spaceship after another, a seven or eight meter long aircraft, and a twenty or thirty meter long shuttle airship.

These things are more suitable for today's human civilization than fourth-tier battleships.

After experiencing the invasion of the alien Zerg, the devastation and the loss of countless lives, the level of human science and technology has actually fallen far behind.

Take the Federation, which had the best defense, for example. It almost lost the entire coast, including the states and cities in the second circle, which means that half of the country’s territory has been lost.

It is also the place with the most developed economy, top universities and technology companies...

In addition, the initial rescue strategy focused on developing heavy industries such as arms and weaponry, and there was simply not enough time to transport away too many high-tech industries.

At most, some technical data backups remain.

The level of human technology has regressed by at least thirty years, and satellite communications have been paralyzed. According to Lin Feng's experience of going to other places to check...

The Federation is still the strongest after thirty years of regression.

Because of Lin Feng's blessing and help, the Zerg Queen and her Zerg army did not destroy a large number of manpower except for the battle in the capital.

Moreover, although the initial federal resistance forces were defeated, at least those fearless soldiers, especially Qin Hu and others, used their lives to buy time for the evacuation of a large number of federal citizens.

Although I became the last survivor, at least I was able to save my life.

Judging from the human reproduction rate, after ten months of pregnancy and the recovery period of confinement, the population can only increase by 20 to 30 percent within a year.

This is based on the example of the more than three-fifths of the childbearing-age population, which can only grow by 30% a year. And these are all newborns. It will take 15 years for them to form a certain social role and serve human civilization.

Therefore, for humans, if they want to defeat the Zerg and regain their former glory, the size of their population is crucial.

Only when you have someone can you have everything.

For example, the large-scale counterattack on the Zerg territory that is currently being prepared requires a large number of people to support it, not only the young and middle-aged people who are fighting on the front line to enhance their awakening and evolutionary strength...

It also includes people in the rear who are responsible for providing logistical support, farming and gathering food, engineering production, weapons research and development, and transportation on various fronts.

In short, if we want to reorganize the national machine, we must have a sufficient population to recover the territories lost by human civilization.

At present, the Federation still has at least 700 to 800 million survivors, which accounts for at least half of the current survivors of the entire human race on Blue Planet.

Other countries, especially some populous countries, have long become the Zerg's development canteens, the Queen's strength enhancers, and the entire Zerg's expansion and development boosters.

Currently, except for the Federation, most of the foreign survivors are actually in the central area of ​​the main continent, an area of ​​yellow sand Gobi and desert that is dry all year round.

On the other subcontinents, there are still some survivors, some are hiding in the desert, some are wandering in the mountains, and many more are raised by the Zerg and become their reserve food and breeding materials for the second-level warrior hunting insects.

And the human superpower gene bank where the Queen Mother specializes in harvesting superpower cells...

These powerful guys on the subcontinent had already arrived at the main continent in advance and fled all the way to the center. Now, except for the main continent, the number of surviving humans on the other continents does not exceed 50 million.

Distributed in every corner, barely surviving.

They can neither form an effective resistance, establish a fixed income base, nor gather into a large scale to continue human civilization.

It can only slowly decay in despair and hunger.

Those individuals and organizations that built shelters or underground bases in advance would not survive long under the Zerg's iron hoofs and excavations.

As for those remaining forces that fled to the center of the main continent, including the 600 to 700 million survivors from dozens of countries, they were equally unusable because they only had a population and no corresponding industrial industries.

Instead of expecting them to launch an effective counterattack against the Zerg, it is better to focus on the internal fighting among the Zerg and ignore their existence.

However, the hope for this matter is about to be dashed.

Because the third-stage late king-world worms are already in the process of gestation, a week later, they will carry the third-stage late queen mothers promoted from other continents to land on the only safe place for humans, the main continent.

But generally not directly into the central area.

Rather, it is on the coastal edge of the main continent.

Firstly, it is to guard against attacks from human weapons. After all, the third-stage late king-level insect has no attack capability. If it is hit by a nuclear missile, it will definitely die.

The third-stage late queen carried in the body and its million-strong Zerg army will be caught in the turbulence of time and space and directly cut into pieces by the sharp blade of space.

In addition, there were also challenges posed by the third-order mid- and late-stage queens along the way.

Moreover, it can only land in low-latitude areas, near the equator or outside the Tropic of Cancer.

The main reason is that Blue Star has entered winter in December. The temperature has dropped sharply in high latitudes and high altitudes, and there have been many blizzards. The low temperature is not suitable for the survival of black-backed worms and king-backed worms. Even third-level king-backed worms hate and cannot tolerate areas with temperatures below zero.

In addition, the permafrost zone is not suitable for the Zerg to dig nests and wormholes, so no Zerg queen has ever landed in high latitudes.

It has also become the place where the largest number of human survivors gather, apart from the center of the continent.

The living environment is harsh even for insect gods, and it is even more so for humans.

In a place where the temperature is ten or twenty degrees below zero, if there is no heating and sufficient food, hunger and cold will take your life before the sharp feet and fangs of the Zerg.

Therefore, most of the survivors gathered in the central area of ​​the main continent.

This place will also be the location for the final peak showdown between the third-late stage Zerg Queen who will land on the main continent in the near future.

Therefore, Lin Feng no longer expects them to be able to take up the banner of counterattacking the alien Zerg, or even to become a main force in the counterattack.

In the end, he still has to rely on the Human Salvation Army he built, as well as the survivors of the Empire and the Old Federation.

And the strength and skill level they retained...

However, they were completely unable to analyze the fourth-order space battleship that they had captured and built by themselves. Even if Lin Feng taught them step by step, or even sent a whole fourth-order space battleship to all the researchers to dismantle and analyze directly, they could not comprehend and digest the science and technology in a short period of time.

If we want to form an industry and replicate it, I'm afraid it may not be possible to start it every few years.

Therefore, directly handing them a Tier 4 battleship and asking them to replicate it one-to-one is like handing a modern chip to an ancient blacksmith. It is simply a fantasy.

Because the level of technological civilization between the two sides is a whole level apart.

Even if Lin Feng persuaded a group of dragon-lizard people from the dinosaur clan to join his salvation army, and let these engineer dragon-lizard people teach human researchers hand-in-hand, it would still take several years of teaching and accumulation to obtain a group of senior scientists belonging to mankind.

After all, there are very few brain evolvers like Ling Shuyan who can awaken the existence of brain evolution. Otherwise, she would not have been able to support the Jincheng Biological Research Institute on her own and compete with the General Research Institute.

In fact, in peacetime, when humans have not been invaded by alien Zerg, if the Federation gathers all its national strength, it can still analyze most of the scientific and technological content contained in a fourth-order space battleship full of alien science fiction in a short period of time.

But the current situation of food, people and equipment shortage can only delay it a lot.

Otherwise, if humans could mass-produce fourth-order battleships, even if it was just all the parts that Lin Feng could put together directly, the alien Zerg would have to be driven out of the Blue Planet, or even outside the Periplanetary belt.

So for Lin Feng, the hundreds of small single-person aircraft and a dozen airships flying below the space battleships floating thousands of meters in the sky are the advanced technological weapons and equipment that mankind really needs.

It was for this reason that Lin Feng used the power of spatial realm to directly shift phase and arrive above the battlefield where a fierce battle was taking place.

At this moment, the other half of the surviving dinosaur clan is fighting a blocking battle with many third-level life puppets attacking from behind, preventing them from destroying the remaining half of the battleship.

There are also thousands of dragon lizards who are using the remaining weapons on the warships to fight against the incoming third-level puppets...

These two-meter-wide cannons have a caliber comparable to that of a small car…

It is equivalent to a 2000mm caliber artillery shell, and is about the same size as a military aerial bomb in human civilization.

A two-meter-wide aerial bomb is equivalent to a ten-ton super bomb. One shot can instantly kill a late-stage or peak-stage second-order tiger-spine worm, or seriously injure a third-stage Zerg.

However, on this half of the fourth-order space battleship, it is only equivalent to an ordinary secondary gun.

The real main gun is located in the middle of the battleship. It is a super cannon with a caliber of five meters, and it is also two hundred meters long!
It occupies one tenth of the battleship's length, but unfortunately it has lost the nuclear-powered furnace in the back half, which serves as its power, so it does not have enough energy for launch.

At the same time, in order to save energy, only other two-meter-level secondary guns can be used to fire high-energy gunpowder shells.

On the left and right of the floating half of the warship, there were countless long iron rods that were deep in the sea water, and they were constantly emitting a series of bubbles, as if they were absorbing the substances inside, or ionizing the oxygen and hydrogen in the Purified Sea...

It seems that they have survived this way for the past month.

Lin Feng then controlled the warship and slowly landed it.

At the same time, the information scanned on the screen in front of them was broadcast to the ship's dormitory area, so that the more than one thousand survivors of the dinosaur clan could view the real-time images outside broadcast on the big screen.

At the same time, there was a video call with Long Yuan, the current leader of the dinosaur clan.

Lin Feng spoke first:

"I just made a space jump, so I can't contact you, and I have to avoid the sight of the third-level king bug."

"Now let me explain the situation. In the past half an hour, we have successfully passed through the space tunnel from the Earth Realm where we were before to the Purified Sea now..."

"It is also where the other half of the space battleship is located."

"As you can see, I have found half of the warship floating on the ocean, as well as the remaining dragon lizard survivors..."

"They are currently fighting with the defenders and guardians here, and the battle is fierce."

"But the warship we modified is only half as good as the original one. Most of the weapon systems have been damaged. Only a nuclear power furnace and a hull remain."

"At this moment, either you land near the half-broken battleship and we will get off the ship to provide support, or you stay farther away and consider how to rescue after landing..."

After understanding the situation, Long Yuan frowned and sighed:
"At first, I just thought that if I could fly, I could escape most of the Zerg attacks. After all, apart from the third-order king bugs, there have been no other sky-type Zergs. Even the third-order king bugs are not good at attacking and can only summon nearby second-order Zergs."

"Besides, the back half of the battleship itself doesn't carry too many weapons. It only adds defense to protect the engine and fusion power furnace."

"For defense, there are several secondary guns with rotating middle parts for support."

"Given the current situation, it is safer to choose the second option. First, land nearby, and then use the maneuverability of the battleship to deal with these guarding Zerg."

Lin Feng nodded, and then according to Long Yuan's instructions, he docked the warship three kilometers away from the scene and suspended it over the Purified Sea.

Then open the armored section on the top of the battleship to allow the dinosaur survivors in the cabin to leave and come onto the battleship.

At this time, Lin Feng also transferred the control authority of the warship to Long Yi in the cockpit. He then flashed in an instant, used the power of space and artistic conception, and shifted phase to above the warship.

In order to ensure the speed of the battleship's escape, the back armor of the battleship was streamlined.

In fact, this is somewhat redundant for space battleships. After all, they spend most of their time in outer space, where there is no air resistance at all.

Even if it lands inside a planet, the powerful engine powered by a nuclear fusion furnace can easily achieve high-powered flying bricks.

It is only now that they are in the folded space inside the body of a fourth-level realm king that they need to consider the influence of air resistance in order to increase the chances of everyone's escape.

If the streamlined deck was filled with survivors of the dinosaur clan, they would all be looking at the fierce battle in the distance.

The dragon lizard leader Long Yuan, with the help of several engineers, has established a temporary communication base station and contacted the half-destroyed warship not far away.

At this moment, through the conversation, the dragon lizard command room on the half-battleship confirmed that this fourth-tier battleship with a strange yet familiar shape...

It is the back half of the Meteor-class advance probe ship!
