Sure enough, then the blood crystal space passed on batch after batch of blood successors, and since the enemy this time was an invisible monster, Li Feng did not bring the newly promoted demon python and these high-level blood successors.

The 10,000 low-level blood successors are almost all from the blood successors of the Black Scale Man and the Spiked Birdman, but with the fully armed fire support of this group of people, it is enough to deal with these invisible monsters.

Everyone was teleported over, and immediately set up their defenses on the mountain, almost every blood successor, they were armed with a light machine gun and a large number of ammunition boxes, and more than a dozen high-explosive grenades stuck in their waists.

In addition, there are a large number of war materials and ammunition materials that are being transported in a steady stream, but they are not the focus of Li Feng's real deal with invisible monsters.

The real plan, with hundreds of engineering troops, in the same place several high-power generator sets, and quickly arranged around the foot of the mountain around the grid circle after circle.

Lin Yang and the others finally understood how the boss was going to deal with these invisible monsters.

Sure enough, as a large number of humans descended on Europa, these invisible monsters somehow sensed that a large number of alien humans had broken into their planet, and the nearby invisible monsters were the first to rush over from all directions.

Of course, this qiē is something that no one can see or touch.

However, since the entire foot of the mountain peak is covered with power grids on the ground at this time, when these large numbers of invisible monsters surround and rush up the mountain.

The surrounding power grids were immediately touched by their true effects, and they saw circles of electricity flickering and jumping, electrifying one invisible monster after another to manifest themselves.

At this time, the 10,000 blood successors who were sent over gasped in unison.

None of them thought of it. The foot of the mountain, which was obviously empty, attracted so many invisible enemies in such a short period of time.

The enemies they had to deal with turned out to be invisible.

"Don't be stunned, everyone is firing with all their might." Li Feng hurriedly shouted loudly.

By this time, he didn't mind wasting ammunition, and the ammunition was gone. The entire earth is his supply ground, and at most it costs a larger sum of money.

After receiving Li Feng's shouting order, these blood successors woke up like a dream, and immediately launched their full firepower to sweep away these invisible enemies who were constantly crossing layer after layer of power grids.

The 10,000 blood successors opened fire in unison, and immediately swept the invisible monsters that rushed nearby into a honeycomb, no matter what surged up at the foot of the mountain, under the strafing of 10,000 light guns, no matter how many they were, it was useless.

However, the consumption of 10,000 machine guns firing at full strength is too huge. Although the Blood Shadow Organization is not short of money, the inventory of ammunition cannot withstand such a random bombardment.

Soon, Li Feng reformulated the plan and only drew 500 people to open fire, temporarily using this to deal with the invisible monsters that kept pouring up the mountain.

It's all an offensive and defensive battle, with an endless amount on one side and an endless amount of ammunition on the other.

Two days, five days. Seven-day ...... Time passes.

From the beginning, only 500 men were dispatched to defend, and as time went on, it became longer and longer. As more and more invisible monsters are scattered in other areas of Europa, more and more are coming this way.

The defense of this massive mountain is also getting tighter and tighter. From the output firepower that only 500 people were needed to defend and resist, it gradually evolved to 1,000 people.

More than 10,000 blood successors have been divided into ten shifts to take turns, attacking 24 hours a day.

The barrels that had been knocked out were almost piled up, and they were all used as weapons. Still down the foot of the mountain to smash the monster.

But the reality is still terrifying, even if a thousand people are now firing with all their might to defend the mountain, but because the entire Europa has gathered more and more invisible monsters.

The 10,000 blood successors transferred by Li Feng still felt endless pressure, and by the ninth day, the 1,000 machine guns finally couldn't hold it.

Li Feng decisively sent another hundred blood successors with heavy machine guns to join the defensive battle.

On the fifteenth day. Thirty heavy machine guns that had already been assembled were sent to the scene one after another.

Finally, with the addition of these thirty super-heavy heavy cannons, the situation has finally stabilized.

In the past half month, the ammunition logistics team on this side of the earth has transported a large amount of ammunition again and again.

The total amount of ammunition it consumed and the supply of ammunition actually alarmed the various countries that received the information, what kind of battle has the Blood Shadow Organization been going on recently, so much ammunition can be used?

The orders for ammunition received by arms dealers from various countries on the earth are connected one by one, which directly increases the price of ammunition on the earth several times.

But even so, there is still a steady stream of invisible monsters pouring in from all directions throughout Europa.

Light machine guns, heavy machine guns, heavy machine guns, heavy artillery of various assemblies, and a large number of incendiary bombs were smashed.

The 10,000 blood successors are divided into ten groups and take turns to fight, except to fire is to fire, and to attack is to keep attacking.

Almost all of them tortured the nerves of these blood successors to the point of numbness, and finally, in such a high-intensity continuous attack output, it was not until the forty-seventh day that everyone finally discovered that the invisible monsters that were constantly pouring up the mountain peak had finally weakened.

"Very good, hold on for another three days, as long as you hold on for another three days, they will be almost finished." Li Feng's eyes were bloodshot, this was the first time he had followed the front line like this, and it was also the only time he had encountered a huge number of monsters that could barely be killed.

If you let these blood successors kill them one by one with cold weapons, how long will it take?

A year? Three years? Or maybe it's a decade, or even more?

Of course, this premise is not valid, even if the bodies of these invisible monsters are fragile and have little defense.

But you can't ignore their ability to ignore defenses after close contact, which is too terrifying and disgusting.

No matter how strong you are, once you are surrounded by them and pounce on you, even if you can kill them, they will still absorb the energy from you before they die.

This kind of energy is not only pure energy, after absorbing the best energy in your body, your flesh and blood, your whole body, and all that you have, will also be included in the category of absorbing energy.

Through these years of experimentation, Li Feng finally understood the horror of those lizardmen cultivating and creating these invisible monsters.

Theoretically, as long as there are enough of them, and they are endless, it means that they have no enemies that they can't deal with, even if you are as strong as a god, as long as there are enough of them, as long as they can get close to you, then you are finished.

This is theoretically an invincible biochemical creature.

Fortunately, with the sparse gathering of invisible monsters in the last three days, Europa, these terrifying invisible invisible monsters, finally have no threat.

This also indicates that from this moment on, the owner of the planet Europa will finally be occupied by Li Feng.

"There are still very few monsters left in Europa, so I will hand them over to Lin Yang and you to lead the team, and destroy all of them as much as possible."

"Yes, boss." Polo hurriedly responded.

The unknown is scary, but if a way to deal with it has been found, then the remaining invisible monsters that roam all corners of Europa are not a problem.

Finally, after nine months, almost a year, Europa's iceworm breeding program was finally launched.

Li Feng, who had been waiting for a long time, was vigorous and resolute in the subsequent large migration process of ice worms.

Since the previous ice worm has been proven, it has the ability to survive in Europa, so now there is no need to try to raise it in one fell swoop, Europa's three microorganisms can give so many biochemical invisible monsters to maintain survival, and Li Feng naturally does not need to care about the number of transgenic ice insects, simply move as many as he wants.

In the glacial land of the Blood Moon World, almost all the ice insects were captured by the million Titan ants sent by Li Feng.

Later, in addition to the remaining more than 10,000 insect species, nearly hundreds of thousands of ice worms were all transferred to Europa's moon.

Not only is it free-range, but if Europa does not have natural predators of ice insects, it will naturally no longer need to be taken care of by people if it is to be cultivated next.

In addition to leaving five observation teams to stay on Europa, Li Feng's plan to breed insects on the entire planet was finally a complete success, with a total duration of nine months and three days.

The only thing waiting now is the harvest season for breeding and growth once every three months, of course, in order to have a larger breeding base for ice insects, it is obvious that Li Feng does not plan to move these ice insects, he must wait until the breeding base of the entire Europa is getting larger and larger, so that the harvest will be larger.

Next, he rushed to Europa almost non-stop, and Europa's success greatly stimulated his anticipation of blood essence collection.

During this nine-month trial colonization period, on the side of the Blood Moon World, Moli Mountain was not idle, and almost every day, a group of blood successors were divided to continuously kill the flying winged snakes of the ghost domain, but they also gathered a lot of thin armor chips condensed by the snakes.

This would allow the Celestial Circle to travel to Callisto, even farther away.

Li Feng replenished the energy and set off directly from Europa, and the voyage of the universe did not know the time.

When the three of them went through an unknown amount of time, from more than a dozen short-range space jumps to a medium-range space jump to the first universe again, Europa, a moon much larger than Europa, finally appeared far away.

Into the orbit of a satellite, into the atmosphere, when the trio set their feet on this piece of land on Callisto, which is actually similar to some of the Earth's barren environments.

This time, Li Feng and the others finally breathed a sigh of relief and learned the lesson of Europa, they carefully circled Europa a few times before landing, and after careful observation, everyone finally confirmed that Calmede had no creatures for the time being, and there were no traces left by aliens.

This made Li Feng very happy in his heart, since there was no unexpected trouble from these assassins, then it would be much easier to handle Ganymede's farm plan in the future. (To be continued......)
