Just as Li Feng was about to approach the frozen lake and collect some specimens of microlife;

Suddenly, his original move forward suddenly stopped his steps, and he saw the pupils of his eyes shrink slightly.

In the reflection of his pupils, he saw rows and rows of strange footprints suddenly appeared on the edge of the ice lake.

These footprints appeared so weirdly and abruptly, more and more footprints were shown out of thin air with dripping water, and the direction in which these footsteps finally approached was actually Li Feng and the other three.

"It's not good, there are invisible and unknown creatures around, get ready for battle." Looking at these strange situations where he only saw footprints appear, but he could never see the figure, at this moment, Li Feng finally understood that the kind of horror sensation a few hours ago was not an illusion at all.

He hurriedly retreated to Lin Yang and the steamroller in three or two steps, and shouted and reminded.

In fact, now Lin Yang and the two don't need Li Feng's reminder, they saw the dense footprints of the lake constantly approaching, and they had already discovered it.

Obviously, these invisible unknown creatures that cannot be seen at all are finally exposed because they climbed up from the lake and still had water on their bodies.

If they hadn't come up from the lake, with the strength of Li Feng and the others, they wouldn't have found any traces of them.

What kind of monster is this? Terrible!

It's too late, but it's fast, just a few tens of meters away, these invisible unknown creatures have gradually surrounded the three of them unconsciously.

The steamroller polo was the first to hold up this feeling of waiting for death and passivity, so he quickly pulled out two metal sinking sticks of more than one meter from his back, and then took them in his hand and twisted each end of the two long sticks violently.

The next moment, he skillfully formed a metal long stick of more than two meters, and with a stick in his hand, the polo shouted and strengthened his courage. He took two steps forward and picked it up.

"Bang bang ......"

Seeing that the heavy metal long stick was swiped a few times, Li Feng's ears heard a series of slashing sounds like heavy objects hitting the flesh.

Polo took the lead in this round, hitting more than a dozen invisible unknown creatures, and this time, it made the unknown invisible creatures wrapped around a little jealous, and those damp footprints that were revealed were obvious. Went back two meters.

"Fortunately, they are not strong, hurry up and kill them, let them run up from the frozen lake more and more in one mile, then we will be finished." Li Feng saw that Polo's attack was effective, and hurriedly seized the opportunity.

At the same time, the movements of him and Lin Yang were not slow, Li Feng didn't think about it, and his whole body collapsed like a curved bow. Then the whole person rushed forward and bounced out.

Facing the air in front of him, he threw a heavy punch.

"Thor Blaster ......" This time, in the face of an unknown large number of enemies, Li Feng did not have any reservations, and this time the Thor Explosion used one-third of the current stored in his body.

After heavy compression, it exploded with strong force and speed, instantly. I saw that around the front of Li Feng's fist, there was a fierce explosion of thunder and lightning explosions.

A ball of lightning that is more than three meters in diameter. The surrounding air was detonated, and a large number of arc currents rushed wildly.

Just this attack exploded with great power, and it was really no less than a small missile with full weight.

Li Feng's punch thunder god exploded, not only blasting a large gap in the large number of invisible unknown creatures surging up from the front, but also finally allowing the three of them to temporarily see the form of these unknown invisible creatures under the raging arc.

I saw it under the field of thunder and lightning bombardment. An unknown life that resembles the body of a child is finally bombarded out by a blur.

What kind of life is this? What monsters?

They were thirteen or fourteen-year-old children, and they also walked upright with two hands and two feet.

But they have only three fingers on their two hands, each in a tri-pronged shape, and six on their toes.

The shape of the head. It's a bit like a light bulb, large at the top and thin at the bottom, with a pair of dead fish eyes that glow with blue blue, and a mouth, the corners of which are almost split to the base of the ears.

Hit by Li Feng's astonishingly powerful lightning blast, these unknown invisible monsters were screaming with their mouths full of sharp teeth.

"Damn, what kind of monster is this? It's disgusting. ”

Li Feng's punch exploded with thunder and lightning, and although the aftermath of the explosion was wide, it could only knock out more than a hundred invisible monsters in their original form.

However, it didn't take long for their newly manifested bodies to disappear again in the next moment, even if many monsters were directly killed by Li Feng's punch, they still couldn't see the dead corpses invisibly.

And looking at the frozen lake not far away, more and more footprints with watermarks climbed up from the lake.

All of a sudden, the three of them, who were completely surrounded by these invisible invisible monsters, felt a tingling in their scalps.

Lin Yang didn't have the thunder and lightning explosion cultivated by Li Feng's thunderbolt, nor did he use the cold weapon Shen Stick made by the Black Xuantie Gu like a steamroller polo, he untied a light submachine gun hanging from his waist and scattered it around.

While strafing, he shouted again and again: "Boss, we have been surrounded, there are so many of these monsters, we can't deal with them at all, get on the plane, me and the old ball cover." ”

At this time, Li Feng no longer talked nonsense, if the current stored in his body was endless, maybe he would have the ability to use the thunder and lightning explosion to kill these more and more invisible monsters one by one.

However, the maximum amount of current that his current cultivation level could store was only enough to support the use of several lightning blasts.

But even so, in order to buy more time for the two subordinates, Li Feng still had no reservations at this moment.

I saw that his hands were clenched forward, and in his unreserved condition, the palms of his two hands were rapidly condensing one compressed small electric ball after another.

Each of these small electric balls is only the size of a dragon's eye, but in fact, it has been compressed many times because of Li Feng's deliberate actions.

Therefore, when more than a dozen small electric balls of dark blue arc light condensed from his hands, the dangerous aura exuded from Li Feng's body at this time was even shocked by the monsters that were constantly surrounding him.

"Ah, give me all death."

Almost all the reserve lightning in the body was pumped out at once. Li Feng's hands were convulsive, and he kept throwing one after another dragon's eye-sized blue electric balls around.

These small blue electric balls that have been forcibly compressed many times have been unstable because of forced compression. When they were thrown out one by one by Li Feng.

In an instant, the invisible monsters surrounding Li Feng and the three of them were all affected by the explosion of these unstable small blue electric balls one after another.

Boom Boom ......

There were more than a dozen violent explosions, almost bursting the ice beneath his feet.

"Let's go. Don't be stunned, let's go. Li Feng used up the thunder and lightning power in his body without reservation, and his body felt weak for a while, but after all, his eleven-fold physique was still there, but there was no drag, and he quickly rushed out of the encirclement with the two of them and returned to the flying machine.

A few people just returned to the aircraft and closed all the hatches for the next moment. Everyone felt the whole flying machine sink slightly.

It turned out that these invisible monsters had already pounced on the entire Celestial Circle Flying Machine.

"What to do? The information we investigated, but it didn't say that Europa had such a terrible creature, grass. ”

The three of them returned to the flying machine, and the tension that had been raised in their hearts finally couldn't help but relax.

This celestial circular vehicle is an alien product that has existed for thousands of years, and its material is not known to be made of. At present, the earth has been unable to bring harm to it by all means. Not to mention breaking through the outer layer and attacking them inside the aircraft.

Even many researchers said that even if the earth used a large-yield nuclear bombing, at most it would only bring a slight damage to the aircraft.

Therefore, the three of them returned to this turtle shell, Li Feng was not in a hurry, what should he do with the road roller?

In fact. He's also abrupt now.

Earth's scientific theories have long since announced that Europa is the only moon with the greatest potential to contain living matter among the many celestial bodies known to be found in the solar system.

But who would have thought that there would be such a large number of these possible lives. And it's invisible, so aggressive.

You must know that these creatures, even if Li Feng used his spiritual power, he didn't find their bodies at all.

Even, even their aircraft retrieval system from an extraterrestrial product was stunned that no trace of them was detected, if it weren't for the fact that they climbed up from the lake and still had dripping footprints all over their bodies to find them in advance, otherwise the three of them would have been really lucky this time.

Just when the three of them were completely relaxed, however, something even more terrible happened at this moment.

"Alarm, critical alarm...... It was found that the unknown creature was attacking the aircraft, and the energy source of the aircraft was currently declining rapidly, so please try your best to get out of the danger of attack, alarm, vengeance alarm, ......"

Suddenly, a violent warning sounded inside the aircraft, which startled Li Feng and the others.

When he reacted, Li Feng hurriedly looked at the energy source icon, and the whole person was not good, the chip he originally brought acted as energy, and it had filled the energy library of the aircraft by nearly sixty percent.

Even if you come to Europa from Earth in a row, the amount of energy stored in the energy bank is still more than forty percent.

Now, the original energy bank of more than forty percent has been reduced to less than three.

My mother, these monsters are able to break through the flying machine that is almost unattacked by any means, and even drain nearly 20% of the energy stored in the aircraft in this way.

This result simply scared several people out of their minds, and these unknown creatures were simply terrifying.

After exhausting all means on the earth, Li Feng and others did not roll this flying machine, but for the first time, they landed on Europa, a bird that does not, but they encountered such a terrifying and supernatural event.

How can this not make Li Feng and others chill, what are these strange and invisible creatures?

At this moment, Li Feng almost scolded his mother. (To be continued......)
