After the airborne cabin was successfully delivered, two fighter jets crashed under the attack of large groups of small fish ships. Lu Jian, who successfully achieved his goal, was not worried and directed the fleet to stay away from the fourth planet.

However, the fleet did not return to its original coordinates, but continued to pay attention to the fourth planet after leaving a distance.

I have to say that the star 581 is too small. Glizzard 581g, which means the distance between the fourth planet and the star is only 0.14 astronomical units, about seventy light seconds, and is less than half of the perihelion of Mercury.

It is not a good thing to be too close to the star. The fourth planet has long been locked by the star tidal lock and always faces the star. Due to the convection of the atmosphere, the temperature difference between the front and back sides of the fourth planet is not very large, but the temperature on the back is low, which is not conducive to the survival of storm star fungi. Therefore, all the airdrop cabins are thrown on the front of the fourth planet.

The maximum temperature on the front is about seventy degrees, which is not suitable for human survival at all, but it can only be considered just right for fungi.

The temperature on the back is at least about minus forty degrees Celsius, and it is covered with ice and snow all year round.

The fourth planet's natural environment is the best, and the protozoological community there is the most concentrated, but the temperature in the morning and evening circle is not completely consistent, the equator is the hottest, the higher the latitude, the lower the temperature, and the poles are in a frozen state.

The most dense protophytes are located on the equator of the morning and evening circle, but it has now become the base camp of the exoskeletons, and there are busy exoskeletons everywhere.

Leaving the morning and evening circle, most terrestrial species stop at one-third of the front, but whether it is the Earth or the fourth planet, there are all extreme creatures. High temperatures only reduce the species and number of organisms, but they are not really barren.

In contrast, the biosphere on the back of the fourth planet is much more prosperous than the front. After all, keeping warm is easier than dissipating heat. The adaptability of organisms to severe cold environments is far greater than that of hot climates. Whether it is constant temperature animals or temperature-changing animals, it is not a good thing to be too high in blood, and they are basically not far from death.

If the temperature exceeds the boiling point, the blood boils... no need to ask, you will be dead until then.

According to human research, exoskeletons should be a constant temperature species. The Expeditionary Force has not found exoskeletons entering high-temperature areas.

However, this does not affect the spread of storm fungi. As long as the temperature does not drop, the fungus activity is completely guaranteed, and the villi-like mycelium drifts away with the wind. It will soon enter the area controlled by the exoskeleton.

Moreover, dispersing with the wind is not the only channel of transmission. External people are not the first victims. Extreme creatures living on the front of the fourth planet are the first wave of unlucky animals. Although heat-resistant extreme creatures are basically small crustaceans and reptiles, the species of the host does not affect the parasites of fungi.

The parasitic organisms bring the fungus to all directions. At the beginning, it was just a small area. Soon, the fungus showed a trend of geometric outbreaks, both plants and animals, within the range of the fungus infection.

Although the bone armor on the surface of the exoskeleton human body can play a certain protective role, the moving joints are not within the protection range. Therefore, these places have become the breakthrough for fungi, and the joint positions of the exoskeleton human body gradually grow slender myceliums. At first glance, it looks like a group of primitive exoskeleton humans wearing grass skirts.

Just from the appearance, it is much more pleasing to the human form of a large group.

At the beginning, fungal parasites did not attract the attention of the upper class of the exoskeletons. They have traveled through hundreds of life planets and seen countless parasitic microorganisms, but none of them could do anything about the exoskeletons.

The immunity of exoskeletons is not vegetarian.

But soon they found that something was wrong, and the biological warship on the fourth planet actually grew a large number of myceliums in their bodies!

The biological warship was originally a cosmic creature, and even cosmic rays could be blocked by the epidermis. It was not so easy to be parasitic, but it was broken that the exoskeleton man had transformed the biological warship and opened up space for manipulation in its body.

The exoskeletons do not have the strict disinfection procedures like humans. The exoskeletons infected with fungi enter the warship and directly bring the fungus into the biological warship... The fortress is always breached from the inside, and this unchanging truth is once again confirmed from the exoskeletons.

By the time the exoskeleton began to face up to this fungus, the storm fungus had spread throughout the fourth planet, and even the creatures on the back of the planet could not escape the disaster. Although the temperature on the back of the planet was low, the protozoa could maintain a constant temperature in the body, which was enough to ensure that the fungus was active.

The expeditionary force that had been observing the fourth planet couldn't help but feel the hair and bones. The microorganisms were indeed invisible killers, hurting the enemy invisibly!

Humans can only observe the surface of the fourth planet, and they have no idea that the situation looks worse than the surface.

Even if a biological warship flies into the universe, the temperature in the body can remain unchanged, and fungi do not infect the surface of the biological warship at all.

As a result, fungi began to spread into the bone tomb as the biological warships that took off, and began to gradually spread among the entire exoskeleton group.

At this time, the entire exoskeleton tribe panicked for the first time. The community lord ordered the digestion of planetary resources to be temporarily suspended and fight against storm fungi with all their might.

The infected individuals and biological warships immediately separated from the community. As a result, the two biological warships with 70% of the bone tombs formed a huge army of infection. In a few days, another bone tomb entered the ranks of infection. In such a large group of exoskeletons, only one bone tomb was left with no fungi found.

The Expeditionary Force was surprised to find that the exoskeletons actually knew how to isolate!

Originally, the Expeditionary Force did not know that fungi had begun to move from the ground to space. It was not until the exogenous ganglion community was divided into two, and even the biological warships patrolling the air were divided into two groups, and they realized that the situation had changed.

But this change is definitely a good thing for humans.

The exoskeleton immediately invested a large amount of resources into research. The exoskeleton, who started with biotechnology, quickly figured out what the storm fungus was, but it was just a clue. How to deal with the storm fungus was without any signs. This fungus is really strange. Even the exoskeleton has never seen such a difficult microorganism!

Various methods are constantly used in the battle to eliminate fungi, but have little effect.

In fact, the biotechnology of exoskeletons is not as mysterious as humans imagined. Exoskeletons do have the ability to change genes, but they do not make subtle adjustments in microscopic forms like humans. They are more of the instincts obtained through continuous evolution.

They know genes and DNA, but they do not understand the composition of DNA like humans, and they cannot separate the microstructure of dan, nor do they know the specific functions represented by a certain DNA fragment.

The techniques of exoskeletons must have reached a meticulous microscopic level in history, but their technologies have lost a lot in the continuous escape. Now they have not reached such a profound level, and they can only rely on their foundation to gain a solid foundation.

Moreover, the number of elites among the exoskeletons is too small, and most of the nobles serve as military commanders. Only a small number of them conduct technical research. The insufficient number of researchers is also one of the reasons why they fail in the fight against fungi.

While the exoskeletons are fully committed to studying storm fungi, humans have not given up studying this strange microorganism.

Compared with exoskeletons, humans have only food supply and parasitic value except themselves. In addition to steel and alloys on the warships, they are also plastics, and they are impossible to parasitize fungi. They are far less parasitic hosts like exoskeletons. Furthermore, in dealing with this malignant infectious microorganism, isolation is definitely the best method.

However, to prevent fungal infection, the laboratory temperature has been maintained at a constant temperature of twelve degrees. Until now, no researchers have infected storm fungi.

Humans have many ways to deal with microorganisms, but they all retreated in the face of this fungus. It seems that there is no effective way to find except for temperature.

Even if the exoskeletons know that low temperatures can deal with fungi, they do not have the freezing technology like humans and cannot eliminate the fungi in their bodies at all.

They accidentally completed a great project that Ye Fei didn't even dare to think about, that is, to fight fungi with an extremely large population, but they didn't know which exoskeleton person could eventually produce antibodies.

In addition to paying attention to the fourth planet, Lu Jian has also been paying attention to the research of fungi. There are not many scientific research in the Expeditionary Force, and there is no special progress in the research of fungi. Apart from clarifying the general structure of fungi, there are no other results.

However, Lu Jian didn't care much. In his mind, it would be better to create a storm fungus variant. If the exoskeleton finds a way to deal with the fungus, he can do it again by copying it. Even if there is no direct damage to the exoskeleton, it is a good idea to disgust them.

It was a whim when I sent Ye Fei to take an immigrant boat to grab a livable planet. When Lu Jian recalled now, he felt that he had the will of heaven in the dark.

Unfortunately, Storm Star probably has no possibility of immigration, unless the global temperature is lowered to a low enough time and then the temperature is raised again.

It is not impossible to do it with human means, it just takes enough time. When the exoskeletons may arrive at any time, the local area cannot extract enough resources to run to more than 20 light years away to transform the planet.

Since there are too few places for parasitism on the exoskeleton human body surface, the speed of exoskeleton human beings is far less rapid than that of human beings. The infection position in biological warships is limited to the position that exoskeleton human beings can reach. The deep inside the body is not able to parasitize, and the impact on biological warships is minimal.

Although the appearance seems to be a little changed, the actual impact is not big. Such discovery finally calmed the exoskeleton who had been nervous and began to resume work on the fourth planet.

Lu Jian was disappointed when he found that the exoskeleton man had the intention of returning to normal, but after all, he delayed the exoskeleton man's time and it was not considered completely unreaped.

Originally, he had expected that fungi would be parasitized for a long time, which could produce some toxicity and eliminate exoskeletal people.

Although Storm Fungus failed to achieve Lu Jian's goal, he also reminded him that after Commander Lu reported the relevant situation to the Tianjun Headquarters, he seized the opportunity to propose the idea of ​​bacterial warfare and viral warfare.

It’s not that humans have never used similar methods, but they must conduct special research on different exoskeleton communities to find the microorganisms that are used. The Expeditionary Force has no ability, and there are no virus specimens. If people sent from Earth, it will take half a year to reach 581. By that time, the exoskeleton had already digested the fourth planet.

Except for how many tufts of fuzz on the exoskeleton's body, everything seemed to have returned to the origin. The Expeditionary Force organized several asteroid attacks. The exoskeleton's counterattacks continued. The Americans also carried out several raids, but there was no result in any battle.

25 May 11, 206.

A violent space fluctuation suddenly occurred on the periphery of the Glitzer 581 planetary system. The Expeditionary Force immediately became nervous and thought it was another community of exoskeletons, but what appeared was not a bone tomb.

Not long after, Lu Jian received a long-lost communication from the main force: "My friend, our main force of smart machinery has just arrived here, so don't worry."

"Your main force?" Lu Jian was very surprised and thought to himself that the main force of mechanical civilization has been following the exoskeleton group? It has only appeared for several months. Is this always following it?

After the main force Six said one sentence, it became easier to remain silent. Another deep and magnetic male voice appeared in the communication: "Hello, General Lu. You can call me the dominant."

"Master?" Lu Jian was stunned for a moment, and suddenly realized something, "You are the earliest one..."

"Yes, I am." The master directly admitted Lu Jian's guess.

"I really didn't expect that I would have the opportunity to talk to you. It's a great honor to know you." Lu Jian sighed. Although it was a machine, it was the earliest individual in mechanical civilization, which had a history of more than 1,300 years. It can be regarded as an old antique.

"General Lu, you have to be polite, it's because I came too late." The master's tone was very gentle, not as stiff as the main force Six. "When I agreed to the alliance with the human race, I didn't expect that you would develop so quickly. You can face the exoskeleton in just a few years."

Lu Jian smiled bitterly when he heard this: "We can't compare with you at all. We have been here for a few months. We still have no choice but to use the external bones. We can only watch them occupy the fourth planet."

"The exoskeleton group is extremely powerful, not something you humans can deal with now... I just scanned the fourth planet, why is the exoskeleton people a little different?" The exoskeleton people suddenly aroused the interest of the master.

Lu Jian had no choice but to say the fungus was released, which made the master laugh.

Fungi poses a potential threat to humans, while individuals of mechanical civilization are completely constructed from inorganic materials. Without the basis of fungal parasitics, storm fungi are completely harmless to mechanical civilization!

Not only storm fungi, but none of the microorganisms known to humans can directly endanger mechanical civilization... Well, I don’t know if mechanical civilization has heard of computer viruses.

Pioneer Four secretly observed humans for more than a year, and it is impossible not to know about computer viruses. But while knowing computer viruses, do you also know what a firewall is, antivirus software and system vulnerabilities are?

However, mechanical civilization has real intelligence and may have similarities with the earth's operating system, but the exact same probability is almost non-existent.

Otherwise, it would be possible for humans to hack into the mechanical civilization system through super hackers, and then directly control the mechanical civilization for their own use...

If the master knew what Lu Jian was thinking, he would probably immediately place humans in the same danger as the external bones. Fortunately, the master did not have that supernatural ability.

The two sides had a brief exchange, and the master quickly proposed the intention of jointly attacking the exoskeleton.

Lu Jian had no objection to this and did not hesitate to pull the Americans into the water.

Anyway, this battle is dominated by mechanical civilization, even if you don’t work hard, you can shake your flag and shout.

Lu Jian also wanted to pull Peter and the master to study the combat plan, but he did not expect that the master directly refused and took the main force of mechanical civilization to attack the fourth planet.

Tens of thousands of mechanical civilizations that looked no different from asteroids rushed towards the fourth planet, which scared Lu Jian.

Peter is not much better. It is true that the combat power of the outer bone man is good, but the combat power of the mechanical civilization is not bad.

It was not until this time that the two people realized that they had been underestimating the strength of mechanical civilization before.

How could they know that the civilization that created the intelligent machinery itself did not know how to fight. The mechanical civilization and the external bones could only be said to be half a dozen. The master has never won a victory in air combat for a long time.

The reason why individuals of mechanical civilization are so huge is to gain an advantage when colliding with biological warships!

However, all this has changed due to the contact between Pioneer Four and humans. Although Pioneer Four provides a lot of advanced technology to humans, in fact, he got a lot from humans. Even the moment he destroyed the bone tomb with one blow was achieved by referring to human technology transformation itself.

The main force of mechanical civilization had indeed followed the exoskeleton group, but after obtaining human technology, the master immediately realized how stupid and rough his previous fighting style was, and he could not mention the word command at all.

If the master who had obtained the treasure took only a few minutes to digest all the human history of war, and immediately made a decision, leaving only the six major surveillance group of exoskeletons, and the rest of the men followed the master to 667c, found a planet with rich minerals, began to refine metals, manufacture weapons and modify themselves.

This is why the Expeditionary Force did not find the main force of mechanical civilization after encountering the large group of exogenous men.

After Ye Fei arrived at 667, he was determined to rush to the habitable planet. Although he had contacted the mechanical civilization and found that the mechanical civilization was conducting mining operations on the sixth planet of 667c, he had not conducted detailed inquiries and understanding.

The main force of mechanical civilization has been modified. This time, the strength of mechanical civilization is almost equivalent to a geometrical flight from unarmed to armed to teeth. Perhaps it is more accurate to call it a transformation.

Tens of thousands of mechanical civilized individuals were overwhelmingly surging towards the fourth planet, and the external bones were not showing any weakness, and a large number of small fish ships flew out of the outer space of the planet.

However, this time the mechanical civilization did not crash into the alien fleet as before. When the two sides had five light seconds left, the mechanical civilization's seemingly asteroid suddenly shot straight beams out of the body, directly cutting the alien fleet towards the mechanical civilization one entire layer.
Chapter completed!
