After the successful delivery of the airborne capsule, the two fighters crashed under the attack of a large group of small fish ships, and Lu Jian, who successfully achieved his goal, was not distressed and commanded the fleet to stay away from the fourth planet.

However, the fleet did not return to its original coordinates, but left a certain distance and continued to focus on the fourth planet.

It has to be said that the star 581 is so small, the distance between the Gliese 581g, that is, the fourth planet, and the star is only 0.14 astronomical units, about 70 light seconds, which is less than half of Mercury's perihelion.

It's not a good thing to be too close to the star, and the fourth planet has long been tidally locked by the stars, always facing 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 side is low, which is not conducive to the survival of the storm star fungus, so all the airborne capsules are thrown on the front of the fourth planet.

The maximum temperature on the front is about 70 degrees, which is not suitable for human life at all, but it can only be considered just right for fungi.

The temperature on the back side is as low as minus 40 degrees Celsius, and it is covered with snow and ice all year round.

The fourth planet has the best natural environment and the most protist communities there, but the temperature of the twilight circle is not exactly the same, the equator is the hottest, the higher the latitude, the lower the temperature, and the poles are in a frozen state.

The protists are most densely populated and most active on the equator in the morning and dusk circles, but it has now become the base camp of the Exoskeletons, full of busy Exoskeletons.

Leaving the dawn and dusk circle, most terrestrial native species stop at the frontal third, but not Earth or the fourth planet. There is no shortage of extreme creatures, and the high temperature only reduces the variety and number of organisms, but it is not really barren.

In contrast, the biosphere on the back side of Planet 4 is much more prosperous than on the front side, after all, it is easier to keep warm than to dissipate heat, and organisms are far more adaptable to cold environments than hot climates - whether it is homeotherms or ectotherms, high blood temperature is not a good thing, and it is basically not far from death.

If the temperature exceeds the boiling point, the blood boils...... Don't ask, if you don't wait until then, you'll already be dead.

According to human research. Exoskeleton is supposed to be a homeothermic species. The expeditionary force has not found the exoskeleton people entering the hot area.

However, this does not affect the spread of the storm fungus, as long as the temperature does not drop, the activity of the fungus is completely guaranteed, and the fluffy hyphae are scattered in the wind. Soon they entered the area controlled by the Outer Skeletons.

And going with the wind is not the only channel of transmission. The Outer Bone Men were not the first victims. The extreme creatures living on the front side of the fourth planet are the first wave of unlucky eggs, although the heat-tolerant extreme creatures are basically small crustaceans and reptiles, but the type of host does not affect the parasitism of fungi.

Parasitic organisms carry the fungus in all directions. At first, it was only a small area, and it didn't take long for the fungus to show a geometric outbreak, and both plants and animals were within the range of fungal infection.

Although the bone armor on the surface of the outer skeleton can play a certain protective role, the movable joint parts are not within the scope of protection, so these places have become a breakthrough for the fungus, and the joint position of the outer skeleton man begins to gradually grow slender hyphae, at first glance, it looks like a group of primitive exoskeleton people wearing grass skirts.

In terms of appearance alone, it is much more pleasing to the eye than the appearance of a human being who grows into a large clump.

In the beginning, fungal parasitism did not attract the attention of the upper echelons of the Exoskeletons, who had traveled hundreds of living planets and seen countless kinds of parasitic microorganisms, none of which could make the Exoskeletons any better.

The immunity of the exoskeleton is also not vegetarian.

But soon they found out that something was wrong, and the creature warships on the fourth planet actually had a large amount of mycelium growing in their bodies!

The biological battleship was originally a cosmic creature, and the epidermis could even block cosmic rays, so it was said that it was not so easy to be parasitized, but the bad thing was that the outer bone man had transformed the biological battleship and opened up space for manipulation in its body.

The Exoskeleton did not have the strict disinfection procedures of humans at all, and the Exoskeleton infected with the fungus entered the battleship and directly brought the fungus into the body of the biological warship...... Fortresses are always breached from within, and this immutable truth is once again confirmed by the Outer Skeletons.

By the time the Exoskeletons began to confront the fungus, the storm fungus had spread throughout the Fourth Planet, and even the creatures on the back side of the planet had not escaped the catastrophe - although the temperature on the far side of the planet was low, the protists could maintain a constant temperature enough to ensure that the fungal activity was not lost.

The expeditionary force that has been observing the fourth planet can't help but be shocked, the microbes are indeed invisible killers, injuring the enemy invisibly!

Humans can only observe the surface of the fourth planet, and they don't know that the situation is worse than it seems.

Even if the bio-warship flies into space, the temperature in its body can always remain the same, and the fungus does not infect the surface of the bio-warship at all.

As a result, the fungus began to spread to the bone mound with the biological warships that had been lifted into the air, and began to gradually spread throughout the outer bone population.

At this time, the entire Outer Bone Great Race panicked for the first time, and the community lord ordered to suspend the digestion of planetary resources and fight against the storm fungus with all its might.

The infected Outer Bone Man and the Biological Battleship were immediately separated from the community, and as a result, the two Bone Piers with 70% of the biological warships formed a huge army of infection, and within a few days, another Bone Tomb entered the ranks of infection, and the huge Outer Bone Giant Clan, only one bone mound with no fungi was found.

The expeditionary force was surprised to find that the exoskeleton man actually knew how to isolate!

Originally, the expeditionary force did not know that the fungus had begun to move from the ground to space, until the outer bone population was divided into two, and even the biological warships patrolling in the air were divided into two distinct groups, and they realized that the situation had changed.

But this change is definitely a good thing for humanity.

The Outer Bone Man immediately put a huge amount of resources into research, and the Outer Bone Man, who started with biotechnology, quickly figured out what the storm fungus was, but it was only a figure, how to deal with the storm fungus but there was no eyebrow at all, this fungus was so strange, even the Outer Bone Man had never seen such a difficult microorganism!

Various methods are constantly being used in the battle to eradicate fungi, but with little success.

In fact, the biotechnology of the Exoskeleton is not as mysterious as humans think. Exoskeletons do have the ability to change genes, but they are not microscopic and subtle adjustments like humans, but more of an instinct acquired through continuous evolution.

They know the genes and DNA of the channel, but they do not understand the composition of DNA like humans, let alone the microstructure of the DAN, nor do they know the function represented by a specific DNA fragment of the channel.

The techniques of the Outer Bone People must have reached the level of meticulous microscopic level in history, but their skills have lost a lot in the continuous escape, and now they have not reached that level of profundity, and they can only rely on their thick foundation to eat the old bottom.

Moreover, the number of elites among the Outer Skeletons was too small, and most of the nobles served as military commanders. Only a small part of the research work is carried out in the field of technology. The lack of researchers is also one of the reasons why they fail in the fight against fungi.

While the Exoskeletons are working the storm fungus, humans have not given up on studying this strange microorganism.

In contrast to the Exoskeletons, humans are in addition to themselves. Only food supplies have parasitic value. In addition to steel, the battleship is alloy. At the very least, it is also plastic, which is impossible for fungi to parasitize, and it is far from having parasitic hosts everywhere like the exoskeleton man. In addition, to deal with this malignant infectious microorganism, isolation is definitely the best means.

However, in order to prevent fungal infection, the temperature in the laboratory has been kept at a constant temperature of 12 degrees, and so far, no researchers have been infected with the storm fungus.

There are many ways for humans to deal with microorganisms, but they are all defeated in the face of this fungus, and it seems that there is no effective means other than temperature.

Even if the Outer Bone Man knows that the low temperature of the Outer Bone Dao can deal with fungi, he does not have the same freezing technique as humans, and he cannot destroy the fungus in his body at all.

They inadvertently completed a great project that Ye Fei couldn't even think of, that is, to fight the fungus with an incomparably large number of populations, that is, they didn't know which of the outer skeletons in the Dao could eventually produce antibodies.

In addition to paying attention to the fourth planet, Lu Jian has also been paying attention to the study of fungi, there are not many scientific research in the expeditionary force, and there is no special progress in the study of fungi, except for figuring out the general structure of fungi, there are no other achievements.

However, Lu Jian didn't care much about it, in his heart, it was better to be able to make a variant of the storm fungus, in case the Outer Bone Man found a way to deal with the fungus, he could do it again according to the gourd painting, even if there was no direct damage to the Outer Bone Man, it would be a good idea to disgust them.

It was a whim to send Ye Fei to take the immigrant ship to grab the habitable planet, but in retrospect now, Lu Jian had a sense of providence in the dark.

Unfortunately, Storm Star is unlikely to immigrate unless the global temperature is lowered low enough to raise it again.

It's not impossible to do it with human means, but it takes enough time, and in the case that the Outer Bone Man may arrive at any time, the local people can't spare enough resources to go to more than twenty light years away to transform the planet.

Due to the fact that there are too few places on the surface of the outer skeleton that can be parasitized, the speed of weakening of the outer skeleton is far less rapid than that of humans, and the location that can be infected in the biological battleship is limited to the position that the outer skeleton can reach, and the depth of its body is not a fungus that can parasitize at all, and the impact on the biological battleship is minimal.

Although it appeared to be a little different on the outside, the actual impact was not significant, and this discovery finally calmed down the Exoskeleton, who had been nervous, and began to resume work on the fourth planet.

Finding that the Outer Bone Man had the intention of returning to normal, Lu Jian couldn't help but be disappointed, but no matter how he said it, it also delayed a lot of time for the Outer Bone Man, and it was not completely ungained.

Originally, he was expecting the fungus to parasitize for a long time, and it could produce some toxicity or something to destroy the exoskeleton.

Although the storm fungus failed to achieve Lu Jian's goal, it also gave him a wake-up call, and after Commander Lu reported the relevant situation to the headquarters of the Heavenly Army, he lost no time in proposing the idea of bacteriological warfare and virus warfare.

Humans have not used similar methods, but special studies must be carried out on different exoskeleton populations to find suitable microorganisms. The expeditionary force did not have that ability, and second, there were no virus specimens. If you send people from the earth, it will take half a year to reach 581, and by that time, the outer skeletons will have already digested the fourth planet.

Except for a few tufts of fluff on the exoskeleton, everything seems to be back to square one. The expeditionary force organized several asteroid attacks. The Outer Bone Man fought back as always. The Americans also carried out several raids, again with no results.

May 11, 2206.

Glise 581, the outer periphery of the planetary system, suddenly appeared violently spatial fluctuations, and the expeditionary force immediately became nervous, thinking that it was another outer bone colony, but it was not a bone mound at all.

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

"Your workhorse?" Lu Jian was very surprised, and thought to himself, didn't he say that the main force of the mechanical civilization had been following the Outer Bone Great Clan? It's been months since it appeared, is this always following?

After the main six finished speaking, it was easy to fall silent, and another deep and magnetic male voice appeared in the communication: "Hello. General Lui. You can call me Juggernaut. ”

"Juggernaut?" Lu Jian was stunned, and suddenly realized in his heart, "You are the earliest ......"

"Yes, I am." The Juggernaut directly admitted Lu Jian's speculation.

"I didn't expect that. I even had the opportunity to talk to you. It's been a pleasure to meet you. Lu Jian sighed for a while. Don't look at it as a machine, but people are the earliest individuals of mechanical civilization, which has a history of more than 1,300 years. It's an antique.

"General Lu is welcome, it's me who came too late." The Juggernaut's tone was very soft, not at all like the stiffness of the main force six, "When I agreed to the alliance with the humans, I didn't expect you to develop so quickly, and in just a few years, you can actually confront the Outer Bone Man head-on. ”

Lu Jian smiled bitterly when he heard this: "I can't compare with you at all, we've been here for a few months, and it's not the same way to take the Outer Bone People, so I can only watch them occupy the fourth planet." ”

"The strength of the Outer Bone Great Race is extremely strong, and it is not something that you humans can deal with now...... I just scanned the fourth planet, why is the Exoskeleton a little different? The appearance of the Outer Skeleton suddenly aroused the interest of the Juggernaut.

Lu Jian reluctantly told the matter of releasing the fungus, which caused the master Ha Lu Ha to laugh.

Fungi are a potential threat to humans, while the individuals of the mechanical civilization are completely constructed of inorganic materials, and there is no basis for fungal parasitism, and storm fungi are completely harmless to the mechanical civilization!

Not only storm fungi, but also all microorganisms known to man, none of them can directly harm mechanical civilization...... Well, I don't know if I've ever heard of a computer virus.

Pioneer 4 has been secretly observing human beings 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 firewalls, anti-virus software and system vulnerabilities are?

However, mechanical civilizations possess true intelligence, and may have similarities with Earth's operating system, but the odds of being exactly the same are almost non-existent.

Otherwise, it is entirely possible for human beings to hack into the system of the mechanical civilization through super hackers, and then directly control the mechanical civilization for their own use......

If the Juggernaut knew what Lu Dao Lu Jian was thinking in his head, he would probably immediately put the human race in the same dangerous category as the Outer Bone Man, but fortunately, the Juggernaut didn't have that supernatural ability.

The two sides briefly exchanged ideas, and the Juggernaut soon proposed an intention to jointly attack the Outer Skeletons.

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

Anyway, this battle is based on mechanical civilization, even if you don't work hard, it's good to wave the flag and shout.

Lu Jian also wanted to pull Peter and the Juggernaut to study the battle plan, but he didn't expect the Juggernaut to directly refuse, and led the main force of the mechanical civilization to the fourth planet.

Tens of thousands of mechanical civilization individuals who looked like asteroids on the surface rushed to the fourth planet, startling Lu Jian.

Peter is not much better, it is true that the combat power of the Outer Bone Man is good, but the combat effectiveness of the mechanical civilization is not bad.

It was only then that the two realized that they had underestimated the strength of the mechanical civilization before.

Where do they know that the civilization that created the intelligent machine itself does not know how to fight, and the mechanical civilization and the outer bone man can only be said to be half a catty. All this time, the Juggernaut has never won an air battle.

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

However, all of this has changed because of the contact between Pioneer Four and humans, don't look at the many advanced techniques that Pioneer Four has provided to humans, but in fact, he has not gotten a lot from humans, and even the moment when he destroyed the bone mound with one blow was realized by referring to the human Being's technical transformation itself.

It is true that the main force of the mechanical civilization has been following the Outer Bone Great Race before, but after obtaining the human technique, the Juggernaut immediately realized how stupid and rude his previous combat methods were, and he couldn't even mention the word command.

For example, it only took a few minutes for the Lord of the Treasure to digest all the history of the human race about war, and immediately made a decision, leaving only the slightly more intelligent main force of the Six Outer Bone Great Race, and the rest of the centaurs followed the Lord to 667C, found a planet rich in minerals, and began to refine metal, make weapons and modify themselves.

This is the reason why the expeditionary force did not find the main force of the mechanical civilization after encountering the Outer Bone Great Race.

After Ye Fei arrived at 667, he devoted himself to the habitable planet, although he had been in contact with the mechanical civilization, and also found that the mechanical civilization was carrying out mining operations on the sixth planet of 667C, but he did not make a detailed inquiry and understanding.

At present, the main force of mechanical civilization has been modified, and this time it is modified, and the strength of mechanical civilization is almost equivalent to a geometric leap from defenseless to armed to teeth, which may be more accurate to call rebirth.

Tens of thousands of mechanical civilization individuals flocked to the fourth planet, and the outer skeleton people showed no weakness, and a large number of small fish ships flew away from the planet's outer space.

However, this time, the mechanical civilization did not crash into the alien fleet as before, and when the distance between the two sides was still five light-seconds, a straight beam of light suddenly shot out from the body of the mechanical civilization that looked like an asteroid, directly cutting off a whole layer in the direction of the alien fleet's direct face to the mechanical civilization.
