As the scenery in front of him changed, Zhang Lang came to a command room full of science fiction.
He was sitting high up in the middle. Diagonally below him, there were more than a dozen operators busy at the console. Directly in front of him was a half-circle of huge electronic screens, which displayed the vastness of space and flashed various data and signs. .
Zhang Lang naturally couldn't understand these data, but Badge gave him thoughtful annotations. At the same time, the background of the current world view was also further improved.
He was in the command room of the central flagship of the Third Human Expeditionary Force. Humanity has only recently discovered the Pron star region. Before that, the other eight races had been fighting fiercely in this star region for a long time. Each of them controlled many planets and had maintained a certain balance. As a new force that has just arrived, humans need to break the balance among the forces with lightning speed and occupy enough planets.
According to the new mission prompt, the condition for victory is to occupy at least one hundred planets within the time limit.
"commander"! "A mechanical voice sounded from beside Zhang Lang: "We have arrived in the Proen star area. According to the information returned by the previous detector, there are eight forces fighting here. Currently, our Third Expeditionary Force is sailing through different spaces and has chosen the Red Manco galaxy in the star area as a landing site. "
Zhang Lang turned around and saw that the person speaking was a robotic face covered with bionic skin. This face had only facial features and no hair. It was impossible to tell the gender and age. The back of the head was connected to a robotic arm and wires. It looked quite... Something weird and scary.
This is the output port of the artificial intelligence system responsible for controlling the fleet. It is made like this to facilitate communication with humans. Usually, the civilian version of this thing will be dressed up as a handsome guy and beauty that makes people drool at the sight of it. However, in the military, everything is practical, and the functions are complete. It does not matter if the appearance is scary.
"Zhuge." Following the prompts from the badge, Zhang Lang called out the codename, or name, of the artificial intelligence.
"What's the reason for choosing Red Manco Galaxy?"
Zhuge still used an emotionless electronic voice to introduce: "This is the most remote galaxy in the Pron star region. There is one star and six planets. The third planet, codenamed Big Dust Star, has been judged to be low-level habitable. Planet. Currently occupied by a small Zerg mother nest. Due to the Zerg's inability to coexist with most intelligent civilizations, they have no allies in this sector. Attacks against them will most likely not involve the intervention of other forces. .”
Zhang Lang listened and looked at the notes on the badge.
The so-called low habitable planets are the classification of the habitability of various planets in the universe by humans in this world.
Taking the earth, the home of mankind, as an example, it is a highly habitable planet for humans. Regardless of air composition, cosmic rays, temperature, gravity and other conditions, it is very suitable for human survival and can basically support human activities on it without any protective measures.
A planet that is one level worse than the Earth is called a moderately habitable planet. Some indicators of this kind of planet are beyond the tolerance of humans (usually air components). It is not recommended for human beings to engage in unprotected activities or be completely exposed for a long time. It can cause harm to the human body, induce diseases and even mutate. But as long as a certain degree of protection is provided, you can stay on it for a long time. .
Even worse planets are called low-habitable planets. This kind requires complete protection before landing. Once fully exposed, it will cause serious damage to the human body and even death in a short period of time.
Although the above three types have different degrees, they can all be considered "habitable planets" for the time being. The criterion is that there are carbon-based organisms on them and they have formed a complete and complex ecological system. It's just that different body structures and different environments they adapt to lead to different livability for different races.
In other words, a planet with low habitability relative to humans may have high habitability for some races. The Earth, the home of mankind, may have low habitability for some alien races that must be well protected before landing.
Because the easiest life forms to form in the universe are carbon-based organisms, the general standard for a "habitable planet" is basically fixed, but the subdivisions of low, medium and high will vary.
But this is not a problem for civilizations with sufficient technological power. As long as the planet can support the survival of carbon-based organisms, then hard indicators such as gravity, cosmic rays, water resources, and temperature are basically the same. Generally speaking, the problem mainly lies in the composition of the air. On the planet, as long as it can be colonized and colonized, it is only a matter of time before it can be transformed into a highly habitable planet.
However, except for "habitable planets", most planets in the universe are classified as uninhabitable planets.
Such planets usually do not have carbon-based life, and many of them do not even have a sufficient atmosphere. The environment above is almost the same as that in space. There is basically no need to transform this kind of planet. It is usually only recorded as a mineral resource. At most, a space base can be built on it to conduct mining, scientific research and other activities.
And the planets that are even worse than uninhabitable planets are called hell planets.
The environment of this kind of planet is more terrifying than the simple space of the universe. It either has extremely heavy gravity, extremely high temperature, or the environment is very unstable. There are earthquakes and hurricanes of staggering scale all the time. Disaster, this kind of planet is a real restricted area, let alone protective clothing. Not even a spaceship dares to land easily.
According to this classification, the big dust star mentioned by Zhuge is at least a "habitable planet", but the environment is a bit harsh for humans.
"How big is this nest?"
"Currently, fungus carpet occupies 30% of the planet's surface, and the number of bugs is estimated to be about 600 million."
"The scale is really not big..." Zhang Lang frowned. According to the badge's explanation, the Zerg are extremely adaptable. Once they occupy a certain planet, they will kill and plunder the biological resources on the planet crazily. At the same time, they will produce a carpet that can absorb solar energy to produce nutrients. Based on this, they will build a complete and simple ecological cycle within the Zerg and multiply wildly until the entire planet is covered with bacteria carpet and become a paradise for the Zerg.
Generally speaking, a planet the size of the Earth, after being completely transformed by the Zerg, can accommodate at least tens of billions of bugs. This one is only 600 million. It can be said that it has just started.
"With such a small scale, it was not taken away by attacks from other forces?" Zhang Lang touched his chin.
"Because the original environment of the Big Dust Star was also very harsh. It was almost on the edge of the habitable standard line. Only the highly adaptable Zerg could successfully take root. Moreover, the mineral resources of this galaxy are not rich, and it can be said that it was occupied by other forces. Abandoned area.”
"That's just right!" Zhang Lang smiled slightly: "This is our first springboard to march into Proen!"
With that said, Zhang Lang issued his first order as commander-in-chief: "Kill all the Zerg and occupy the Great Dust Star!"
