End of the World: My Items Can Be Upgraded Infinitely

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

Seeing one small spaceship after another, a seven- or eight-meter-long aircraft, and a twenty- or thirty-meter-long shuttle airship, Lin Feng drooled.

These things are more suitable for today's human civilization than the fourth-order battleship.

After experiencing the invasion of the alien Zerg, the devastation and devastation of the world, the level of human science and technology has actually fallen behind.

Take the Federation, which has the best defense and resistance, for example. It has almost lost the entire coast, including the states and cities in the second circle, which is equivalent to half of the country has been lost.

And it is the place with the most developed economy, top universities and technology companies...

In addition, the initial rescue strategy is mainly based on the development of heavy industry of arms and weapons equipment. It is simply too late to transport too many high-tech industries.

At most, some technical data backups are left.

The level of human technology has regressed by at least 30 years, and satellite communications have been paralyzed. According to Lin Feng's experience of running to other places to check...

The Federation is still the strongest in this 30-year regression.

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

And although the resistance of the Federation in the early stage was 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 people.

Although they became the last survivors, at least they could save their lives.

According to the human reproduction rate, after ten months of pregnancy, plus the recovery of confinement, the population can only increase by 20% to 30% in a year.

This is based on more than three-fifths of the childbearing population of childbearing age, which can only increase by 30% a year, and they are all newborns. It will take fifteen years before they can form a certain social role and serve human civilization.

So for humans, if they want to defeat the Zerg and regain their former glory, the number of people is crucial.

Only with people can we have everything.

For example, the counterattack on the Zerg territory that is currently being prepared requires a large population support, not only the young and middle-aged people who fight 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 collecting food, engineering production, weapons research and development, and transportation on various fronts.

In short, if you want to reorganize the national machine, you must have a sufficient population to recover the lost territory of human civilization.

At present, the Federation has at least 700 million to 800 million survivors, which at least accounts for the current number of survivors of the entire Blue Star human race.

Other countries, especially some populous countries, have long been reduced to the Zerg's development canteen, the Queen's strength enhancer, and the entire Zerg's expansion and development helper.

At present, except for the Federation, most of the foreign survivors are actually in the central area of ​​the main continent, a dry yellow sand Gobi and desert land all year round.

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

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

The powerful guys on these subcontinents have come to the main continent in advance and fled all the way to the center. Now, except for the main continent, the number of humans who survived on the other continents does not exceed 50 million.

Distributed in various corners, lingering.

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

They can only decay slowly in despair and hunger.

Those individuals and organizations who built shelters or underground bases in advance will not survive for too long under the iron hoofs and excavations of the Zerg.

The remaining forces that fled to the center of the main continent, including the 600 million to 700 million survivors from dozens of countries, are also unusable because they only have a simple population and no corresponding industrial industries.

It is better to think about the internal fighting of the Zerg and ignore their existence than to expect them to form an effective counterattack against the Zerg.

However, the hope of this matter is about to be shattered.

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

However, they usually do not enter the central area directly.

Instead, they stay at the coastal edge of the main continent.

One is to guard against human weapons attacks. After all, the third-stage late king realm worms really have no attack capabilities. If they take a nuclear missile, they will definitely die.

The third-stage late queen mother carried in the body and its millions of Zerg troops will be involved in the turbulence of time and space and be directly cut into pieces by the sharp blade of space.

In addition, there are also difficulties caused by the third-stage middle and late queen mothers along the way.

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

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

In addition, the frozen land is not suitable for the Zerg to dig nests and wormholes, so no Zerg queen has landed in high-latitude areas.

It has also become the place where the most human survivors gather except for the center of the continent.

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

In a place with a temperature of more than ten or twenty degrees below zero, if there is no heating and sufficient food, hunger and cold will kill you before the sharp feet and fangs of the Zerg.

So most of the survivors still gathered in the center of the main continent.

And this will also be the place where the third-stage late Zerg queen who will land on the main continent soon will have the final peak showdown.

So Lin Feng no longer expects them to be able to take up the banner of counterattacking the alien Zerg, and they can't even become a main force in the counterattack.

In the end, it still depends on the human salvation army that he built by himself, as well as the survivors of the empire and the old federation.

And the power and technical level they retain...

But they can't analyze their own captives and build the fourth-stage space battleships by themselves.

Even if Lin Feng taught them step by step, or even sent a whole fourth-order space battleship to all researchers to disassemble and analyze directly, they could not comprehend and digest the science and technology in a short time.

If they want to form an industry and copy it, I am afraid that it may not be started every few years.

So directly handing them a fourth-order battleship and then asking them to copy it one-to-one is like handing a modern chip to an ancient blacksmith, which is simply a fantasy.

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

Even if Lin Feng persuaded a group of dragon lizards of the dinosaur clan to join his salvation army and let these engineer dragon lizards teach human researchers step by step, it would take years of teaching and accumulation to obtain a group of senior scientists belonging to human beings.

After all, brain evolutionists like Ling Shuyan who can awaken the existence of brain evolution are very rare, otherwise she would not be able to support the Jincheng Biological Research Institute by herself and compete with the Research Institute.

In fact, in peacetime, when humans were not invaded by alien Zerg, a fourth-order space battleship full of alien science fiction, if the Federation gathered the strength of the whole country, could still analyze most of the science and technology contained in it in a short time.

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

Otherwise, if humans can mass-produce fourth-order battleships, even if all the parts are just for Lin Feng to piece together directly, the alien Zerg will have to be driven out of the blue planet, or even out of the periplanetary belt.

So for Lin Feng, the hundreds of small single-person aircraft and more than a dozen airships flying below the space battleships floating at an altitude of thousands of meters are the advanced technology weapons and equipment that humans really need.

It is for this reason that Lin Feng will use the power of space artistic conception to directly transfer a phase and arrive above the battlefield where fierce fighting is taking place.

At this moment, the other half of the surviving dinosaur clan is fighting a blocking battle with many third-order life form puppets attacking from the rear to prevent 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 with a caliber comparable to that of a small car...

Equivalent to a 2000mm caliber shell, which 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, which can instantly kill a late-stage or peak-stage tiger spine worm, or seriously injure a third-level Zerg.

On this half of the fourth-level space battleship, it is only equivalent to an ordinary secondary gun.

The real main gun is located in the middle of the battleship, a super giant cannon with a caliber of five meters, and it is also two hundred meters long!

It occupies one-tenth of the length of this battleship, but it is a pity that it loses the nuclear power furnace in the back half, which is its power, and it cannot have enough energy to launch.

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

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

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

Lin Feng then controlled the warship and slowly landed.

At the same time, the information scanned on the screen in front of him was broadcast to the ship cabin dormitory area, so that the more than 1,000 survivors of the dinosaur clan could view the real-time pictures outside on the big screen.

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

Lin Feng spoke first:

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

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

"It is also the location of the other half of the space battleship."

"As you can see, I have found the half of the battleship 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 battleship we modified is only half of the original one. Most of the weapon systems have been damaged, leaving only a nuclear power furnace and a shell."

"At present, either land near the half of the battleship and we will go down to provide support, or stay 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, except for the third-level king worms, there have been no other sky-type Zergs. Even the third-level king worms are not good at attacking and can only summon nearby second-level Zergs."

"And the back half of the battleship itself does not carry too many weapons. It only stacks defense here to protect the engine and fusion power furnace."

"For defense, there are several secondary guns in the middle that can rotate for support."

"In 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 Zergs."

Lin Feng nodded, and then according to Long Yuan's instructions, the battleship was docked three kilometers away from the scene, suspended on the Purification Sea.

Then he opened the armor plate on the top of the battleship, allowing the dinosaur survivors in the ship to leave the interior and come to the battleship.

At this time, Lin Feng also handed over the control authority of the battleship to Long Yi in the driving command room, and he flashed in an instant, using the power of space and artistic conception to phase shift to the top of the battleship.

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

In fact, this is a bit redundant for space battleships. After all, they stay in outer space most of the time, and there is no air resistance at all.

Even if they land inside the planet, the powerful engine powered by the nuclear fusion furnace can easily achieve a powerful flying brick.

It's just that in the folded space inside the body of the fourth-level king, the influence of air resistance needs to be considered to increase the chances of everyone's escape.

If the streamlined deck is full of dinosaur survivors standing, they all look at the fierce battle in the distance.

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

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

is the second half of the Meteor-class advance exploration ship!
