As soon as the three-dimensional image of the unknown creature appeared, a sharp and piercing sound immediately sounded around, and the startled Luo Xu hurriedly guarded, and the weapon locking system was turned on, ready to start.

This kind of sharp and high-frequency sound is very unpleasant, it varies from short to long, Luo Xu suddenly realized, this voice is not a random and meaningless noise, it sounds very regular seriously, is it the language of unknown intelligent creatures?

"Bob, did you record it?"

Without Luo Xu's nonsense, the recorded audio analysis immediately appeared on the mechanical interface, and the audio analysis continued to expand as the voice of the unknown creature continued.

"Huh, this sound seems to be repeating itself?"

After the three-dimensional image appeared, there was no sign of attack, Luo Xu tensed for a moment, and then turned his attention to audio analysis, but after a while, he found that this long audio was divided into several segments, and the peaks and valleys of each segment at the same time point were exactly the same.

"So this thing is talking to me repeatedly?" Luo Xu coughed twice, "Should I say hello?" ”

Seeing that the three-dimensional image repeated the sound five times, Luo Xu raised his hand and smiled: "Hello! ”

It's a pity that his smile is hidden by the helmet, and the three-dimensional image on the opposite side can't be seen, which can't but be said to be a pity.

After the greeting was called, the three-dimensional image did not respond at all, and it still stood in place and made a harsh and sharp sound, Luo Xu felt that something was wrong, the three-dimensional image projected by this projection did not seem to be a real-time image, but a program that could be set up in advance.

"Alas, I knew that I was really scared of myself."

Luo Xu couldn't help but laugh, expelled his nervousness, and took a few steps forward, wanting to see where the device that activated the three-dimensional image was hidden.

"Uh, what's going on? The sound stopped? ”

Luo Xu turned his head, and the three-dimensional image had disappeared, and the sharp and piercing voice was even more missing, as if it had never appeared. The only thing that can prove that it was not a hallucination just now is the sound analysis record saved by the Luo Xu X2 armor. An ominous premonition took root from the depths of the heart, and within seconds it had matured and clung to the fiery heart.

"Bob, what's going on?" Luo Xu couldn't help but ask.

"Sir, no anomalies found."

Bob's answer was still cold and cold, but it was precisely this voice that calmed him down, "Maybe I'm too nervous." ”

Turning around, the light emitted by the slate dimmed at a speed visible to the naked eye, and before Luo Xu could blink, the slate had returned to its original black appearance.

"Well, can anyone tell me the point of everything that happened from start to finish?"

Luo Xu stretched out his hand and said helplessly.

"No, something's coming."

Luo Xu's face changed instantly, and his heart that had just breathed a sigh of relief was pinched again, and X2 suddenly amplified the extremely weak voice, "...... of the water", a bit like a faint sound caused by insects crawling, "Bob, where did the sound come from?" ”

The result of the inquiry was that the mechanical interface marked the entire ground of the square in the distance with hundreds of orange dots, which made Luo Xu stunned by a flash, and the source of this sound turned out to be the ground of the square, but under the illumination of the searchlight, there was nothing on the ground of the square, and it was bare and even dusty.

The X2's sensors don't make mistakes, and its computer doesn't allow such low-level mistakes, so where is the sound coming from?

"Underground!"

Luo Xu gasped, just as he said these two words, the originally neat and clean stone floor of the square suddenly revealed a dense and countless small holes, and as soon as those small holes were revealed, countless black torrents suddenly surged out of it, but in the blink of an eye, the extremely wide square was all covered with black trends.

"I, I ......"

Luo Xu was dumbfounded, coughed a few times, and spit out a few words: "God, are you playing with me?" ”

The neuromechanical interface continuously and automatically collects information, magnifying the black tide stirring in the distance tenfold, and presents the secret of the black tide in front of him: a black bug less than three centimeters in length, the bottom and back are covered with feet for movement, and there is a curved red hook at the end of the body, the image is not only disgusting, but also makes the soles of people's feet cold.

"This is, the centipede on the first pattern?"

The centipede depicted in that pattern was really impressive, so as soon as Luo Xu saw the enlarged image of the insect, it was immediately linked to the memory in his mind.

"I ...... Why so many? ”

Luo Xu wanted to burst into foul language, no matter who saw it, there were countless of them, and the weird insects that covered hundreds of thousands of square squares couldn't help but burst into foul language, no, it wasn't a foul mouth, but he was directly scared stupid. Moreover, these so many impermeable centipede insects are still doubling at a doubling rate, and in less than ten seconds, the black tide has risen to a height of more than ten centimeters, and the number of insects is only afraid of crossing the 10 million mark.

"No, I have to run away, no, not to escape, it's a strategic shift."

Luo Xu didn't say that he was stupid, but when he saw tens of millions of insects, he also felt cold sweat in his palms and feet, and the lower left corner of the mechanical interface reminded him that the real-time data of his heartbeat had climbed to 110 beats per minute. However, as soon as he moved, Bob suddenly reminded: "Sir, the entrance and exit have been blocked, please find another way out." ”

"What?"

Shock mixed with a hint of anger, in the magnified image, the exit four hundred meters away in the distance was indeed drowned in the black tide, and even the crack in the door could not be seen. It's only been about ten seconds, things have been twists and turns, critical situations have happened one after another, and even the exit for him to come in has been blocked, and now he is completely trapped in this building.

Fortunately, he still has x2 exoskeleton armor to cover his whole body, and he doesn't worry about his life when facing these creatures, otherwise today next year will be his taboo, so many insects, even if Luo Xu puts a hundred K500s by his side, he doesn't dare to say that he will ensure his safety, but with X2, it's different.

What he hated was that he knew that there was no danger, and Luo Xu never wanted to face these things, when he thought of being covered by dense layers of alien insects, a bad chill haunted his heart, he was not afraid of terrifying creatures or disgusting creatures, and even dared to experiment with them, but this did not mean that he wanted to be close to disgusting creatures, especially things that he hated intensively.

"Click."

The armor of the left arm was suddenly opened, and the rotating machine gun extended from the inside, covering the arm with a few deformations, and the black muzzle of the gun directly faced the black tide that gradually spread.

"Don't come here, I'll shoot if I come again!"

Luo Xu's threats were useless, because this man who did not keep his promise was shot in the middle of the threat.

"Woo Woo ......"

The rotary machine gun driven by the direct current motor, as the instantaneous explosion bomb of the bullet, abandons the propulsion effect of the base drug, and obtains more space for filling new explosives, resulting in the power of this improved instantaneous explosion bomb, which is several times more powerful than the instantaneous explosion bomb developed by modern countries in the 21st century.

Unfortunately, this situation is like a flood being hindered for a while, stirring up a splash, and then spreading towards the stone steps with a faster and more violent trend, and even if dozens of instantaneous explosion bullets are fired, a few splashes of water cannot turn over the big waves.

"Oh no......"

Luo Xu's face changed, there were too many alien insects, and the power of the instantaneous explosion bomb could not cope with it at all, but in addition to the instantaneous explosion bomb, the laser that was more powerful than it could only deal with a single object, not to mention the laser-guided bullet that was weaker than it, then there was only one choice left, the small homing missile behind the X2. However, in the confined building space, the damage caused to the building by using a tracking missile could be fatal, and this is not the weapons testing room in Base 17.

Luo Xu was not a hesitant person, his mind was quickly determined, his eyes rolled, and the weapon and equipment options for activating the tracking missile were confirmed.

"Click!"

The x2 black-gray, full of power and beauty of the back, turned over from the left and right in the middle, two small homing missiles with a length of more than ten centimeters were ejected by the bracket, and in less than 0.1 seconds, the ignition in the air was violently shot, and an arc was drawn and fell fiercely on the stone steps below.

"Boom !!"

The two missiles slammed into the stone steps, immediately triggering a loud bang that shook the sky, and the incomparable force of the worship shattered the earth, shattering countless fist-sized stones and flying in all directions, and the stone steps made of the strongest stone, like garbage made of white meat and tofu, were shattered in the air waves and flames formed by the explosion. The black alien insects that had already spread to the stone steps were directly vaporized under the endless stream of light and heat arrows in an instant, and they couldn't even support it for a short second.

When the power caused by the explosion gradually stopped, two astonishing large craters appeared on the wide stone steps, with a diameter of at least more than ten meters, which showed the power of the explosion, and the spread of the black alien insects were directly vaporized, not to mention, even the momentum was beaten back, and they were forced to retreat.

Luo Xu was a little embarrassed, thinking that there were still fourteen tracking missiles in his back, and he couldn't help but wonder if he had made it too powerful? Since the last time he encountered the second cube, when facing the alien monster, the power of the homing missile was too weak, and as a result, it was almost impossible to pose any threat to the alien monster, he had learned hard and decided to increase the power of the small homing missile. So in the improved tracking missile, he unscrupulously mixed octanitrocubeane, which was used to test in actual combat, and sure enough, the power was more than twice as large as the original, and at least five times as great.

"I said, how dare you come?"

The astonishing effect of the explosion put a stop to the tide of the alien bugs, but after only a few breaths, the black tide surged up again, drowning two large craters with a diameter of ten meters in a moment.

(Someone said that I would be a eunuch, I was so angry that I trembled, I was so angry that I exploded, and I will continue to watch two shifts tomorrow!) ）
