In the life plan of Colonel Chen Feng, the instructor in Gao Tian, ​​he had thought countless times about resigning and returning to his hometown to slaughter pigs.

It's exhausting. It's so tiring to outwit and outmaneuver those idiot students.

Especially the high sky.

I hope there will be no high sky when I go home to raise pigs.

......

Cosmic year 3250.

Since the first day that mankind entered the universe, the exploration of the universe has never stopped, and it is changing rapidly.

From our first step onto a planet beyond Earth to now traversing numerous star systems, humanity has discovered countless treasures in the vast universe—mineral planets, energy planets, and so on—but no habitable planets.

Compared to the crowded Earth when it was divided among more than 200 countries, humanity has now entered the space age, united against external forces. Nationality is no longer important, and race is irrelevant. A great human federation has been established to jointly develop star system motherships and space stations, and the number of human races has expanded to 600 billion.

Earth is the home planet of humankind, inhabited only by the upper echelons. Most people born in the interstellar age spend their entire lives on artificial satellites and space stations built on mineral-producing or energy-producing planets, never setting foot on the Earth's surface until their death.

While a terraforming satellite that could be made habitable is not much different from a small planet, it is not a real planet after all. The atmosphere, water, and food are all artificially synthesized, the air is always filled with chemical substances, there are no plants or soil, and the lush greenery on the street and the chirping of birds in the branches are all holographic projections.

High society figures wouldn't live on such an artificial satellite; the environment would be too oppressive for humans.

Humanity needs more natural planets.

Unable to develop a new habitable planet, countless people tried to move back to Earth, hoping to obtain permanent residency rights on their home planet.

However, wealth is inexhaustible, while Earth's resources are finite. Although the Alliance banned Earth immigration twenty years ago, illegal immigration and migration for reasons such as marriage and work continue unabated, resulting in an explosive population of 260 billion on Earth, putting the planet's ecosystem in grave danger.

The search for truly habitable planets is urgent.

*

In November 3294, an extraterrestrial space station detected a mysterious signal. After decoding, it was found to be a key containing a cosmic coordinate. Observing the coordinate revealed a cosmic wormhole with an unknown destination on the other side. It was unknown who sent the key, what the sender's purpose was, or whether they intended to send someone to search for the unknown distance.

After exploratory robots scouted the area, the Earth Federation voted to send an aerospace force fleet on a long-distance expedition to explore the wormhole.

In December of the same year, the space force's exploration ship lost contact after entering the wormhole and has been missing ever since.

*

In 3305, twelve years after the Space Force's exploration ship lost contact during a long voyage, a message arrived from an extraterrestrial space station: the exploration ship had reconnected. A wormhole led directly to the Rosette Nebula, 35 million light-years outside the solar system, and a massive galaxy was discovered at its boundary. This galaxy system was infinitely similar to the Milky Way, but had more colorful stars and much larger spiral arms. After its discovery, this galaxy was named the Qili Galaxy.

The Qili Galaxy also contains countless stars and planets. Among them, a habitable planet similar to our solar system has been discovered. It has a mass 25 times that of Earth and preliminary observations show that it has a suitable temperature, atmosphere, water, and life. It is the 65th planet explored in the Qili Galaxy and has been named Qili 65.

*

This news was met with cheers from all of humanity.

*

Humanity is determined to obtain the massive habitable star 65 in the Qili Galaxy.

However, the first landing probe brought back a nightmare for all cosmic life – the planet had been invaded by the Zerg.

The Zerg are the nightmare of all cosmic life. There is an old saying on Earth: "Where locusts pass, not a blade of grass grows." Wherever the Zerg pass, not only does not a blade of grass grow, but the core of a planet is also gnawed into stone fragments.

Earth's problems are becoming increasingly severe, and resources are even dwindling. Modifying satellites also requires resources, and the conditions for the formation of habitable planets suitable for human survival are extremely demanding. In hundreds of years, only this one large, habitable planet has been discovered. If we abandon this habitable planet, it's uncertain whether humanity will even survive another century.

When the Zerg swarms together, they use their unique psychic power to create a canopy that seals off the battlefield. All intelligent, unmanned machines will malfunction, rendering the swarm tactic useless, and drones and androids will all become scrap metal.

To seize this habitable planet from the Zerg, it's obvious that the only thing capable of standing against them is... a massive human sacrifice. Regardless of losses or casualties, ground troops will land and engage in close combat; as long as they can take the planet, nothing else matters.

If one person can't fight off a meat grinder, then hundreds or thousands will pile up on top. The interstellar human era has no shortage of people; tens of millions of bones and blood can always bring a killing machine to a standstill.

......

In 3306, the Human Federation decided to launch a full-scale landing on Planet Qili 65. On that day, hundreds of thousands of starships and mechs approached Planet Qili, and the war between humans and insectoids over the planet officially began.

The war between humans and insects has lasted for five years, and there is still no clear winner.

Human society intelligence.

Human ABO genders are divided into three types: alpha, beta, and omega. Omega is rare, accounting for only 2% of the total population. Alphas are slightly more numerous, accounting for about 38% of the total population, and the remaining 60% are betas, which are evenly divided.

Human sexual characteristics are further divided into male and female, so there are six sexes in humans: male A, female A, male B, female B, male O, and female O. Among them, ABO sex is dominant, and male and female sexual characteristics are only physical features.

Male A: Pure male, physically strong, with a fertile period. Infertile himself, but can easily impregnate others.

Female A: Female with a masculine body, strong physique, and a fertile period. She is infertile herself but can easily impregnate others.

Male B and female B: both are hermaphroditic, but their reproductive capacity is relatively weak, and it is difficult for B to give birth to AO.

Male O: Male-type mother, weak constitution, has a FQ period, easily conceives, but cannot impregnate others.

Female O: Pure mother, weak constitution, has a FQ period (a period of intense sexual activity), easily conceives, but unable to impregnate others.

*****************

Zerg lore:

The Zerg are divided into two types: one is the unintelligent Zerg beasts, low-level mammals, rapidly reproducing interstellar locusts that devour planets and are widely distributed throughout the universe. They attack and invade intelligent races (similar to alien hordes), are interstellar invasive species, are hostile, and eat people.

One type is the advanced Zerg (humanoid female and male Zerg), an intelligent race, a technologically advanced cosmic overlord Zerg empire, the only Level 5 civilization in the local universe.

Although both Zerg are called Zerg, they are not subordinate to each other and are different species. This is similar to how all mammals are of the same origin but have developed into intelligent races such as humans and other wild beasts.

Humans are fighting against non-intelligent, alien insectoid beasts, not the advanced insectoid race.

The human and advanced Zerg territories are too far apart; they have never encountered each other and are unaware of each other's existence.

*

The lower-level insectoid races existed before the discovery of Star 65; they are considered interstellar pests. Before the discovery of Star 65, these lower-level insectoid races had already invaded the Milky Way, and the war between humans and insectoids had been going on for at least a century.

All intelligent races, including the advanced Zerg, will exterminate lower-level Zerg or Beast races near their own civilizations; they will wipe them out as soon as they are discovered.

If low-level insectoids multiply and develop rapidly, they will devour all planets. If they lack food, they will invade and prey on intelligent races (insect swarm invasion).

*

This story features a surreal setting where humans don't possess the mental power to control mechs in combat. The mechs are small, close-fitting, technologically advanced suits similar to those used by Iron Man. Humans primarily rely on A's physical strength and the technologically advanced weaponry they have developed to fight against the insectoid beasts.

A strong mental force is a racial characteristic of extraterrestrial beings (the queen of lower-level insectoid beasts, and the higher-level insectoid race).

*

Humans call the lower-level insectoid beasts the "Zerg" because humans and the higher-level insectoid beasts have not yet encountered each other and are unaware of each other's existence. At this moment, from the human perspective, the lower-level insectoid beasts are the Zerg (this misunderstanding will be cleared up later).

Earth, 3311.

Zerg data analysis meeting at the Fourth Military Region Research Institute.

"Among all known carbon-based life forms, excluding single-celled organisms and some invertebrates, humans are arguably the weakest in terms of physical strength. It was only after we developed warships and mechs that we were able to conquer the stars."

A male researcher wearing a white lab coat and glasses explained the materials projected onto a screen in front of him to a group of high-ranking military officials.

Under the cold, focused, and intimidating gazes of the military leaders, he struggled to suppress the trembling in his legs, straightened his back, organized the materials in his hands, and switched to a different projector.

"And the Zerg can be said to be the most physically powerful of any known species per unit mass."

"We still don't have much specific data on the limits of the Zerg, so we have to use insects on Earth as analogies. Ants can lift objects fifty times their own weight, dung beetles can pull dung balls a hundred times their own weight, and the slashing arm of a praying mantis can easily cut through paper. If we were to enlarge their size to one ton..."

He paused for a moment, then clicked on the next page, and some very impactful images that challenged the human spirit appeared on the projector.

"They can easily knock down mechs, drag away spaceships, and cut through alloy plates; with their armor strength increased ten million times, they are practically invulnerable to blades and bullets. Ordinary nuclear weapons and bullets can hardly harm them; only high-powered light energy weapons and electromagnetic pulse weapons can still strike and restrain them."

"In addition, as we all know, the psionic canopy on the Zerg battlefield will disable remotely operated machines, rendering all unmanned systems useless, and soldiers will have to take to the field themselves."

"The Zerg eat everything; their diet includes almost all organic matter. Most Zerg prefer carbohydrates and proteins, but they won't refuse fat either. Nutrient-rich human bodies encased in mechs are their favorite food; the remains of a single soldier are enough for the Zerg queen to produce thousands of larvae."

"Take the ant colony, the most numerous of the insectoid races, as an example. The queen ant can create tens of thousands of ant soldiers in just a few days. The claws of soldier ants can account for one-fifth of their body length, and the size of ants has increased to ten thousand times their current size. They can easily bite through armor and crush human bodies. It takes more than three of our soldiers to stop and eliminate a single ant soldier. With the queen ant around, their reproduction rate is..."

He seemed to run out of things to say at this point, and tried to organize his thoughts to make the report less scathing.

But he failed.

"The Zerg's reproduction rate will far exceed our ability to eliminate them. Considering the current armament level of the Earth Federation, we anticipate excessive casualties and lack any effective countermeasures. Based on our current data analysis, our research institute's opinion is:"

"The only option is to abandon this habitable planet."

......

In the fifth year, amidst the consistently high rates of injury and death among soldiers, public opinion surged, and humanity finally could not hold on any longer. The masses and the military began to put pressure on the parliament, which had no choice but to make the decision to completely withdraw from the habitable planet Qili 65.

This war between humans and the Zerg for living space ultimately ended in human defeat.

......

******************

......

The fifth military satellite was launched in 3311.

The news of the withdrawal from the Qili 65 star system has just arrived. The five-year tug-of-war between humanity and the Zerg has finally ended in defeat. This means that all the costs invested in the past five years have sunk into the sea of ​​stars, and all the officers and soldiers who sacrificed their lives have been sacrificed in vain.

These past few days, a faint layer of dark clouds has been hanging over the military region.

Gao Tian returned to his dormitory after a day of meetings.

The combination lock recognized his face and beeped twice to open.
