The activated unmanned weapon, a mechanical creature in the shape of a bee with wings that vibrate the air, hovers on the top of a tall building, surrounding the two uninvited guests.

"Come on, I've found the passage to the inside of the building. ”

When he got up, he accidentally pressed a block to activate the mechanism on the roof of the building, and the pure white block a few meters away sank, revealing the stairs leading to the interior, and he found that the boy who was accidentally found climbed and climbed with the blonde girl into the passage.

After a few seconds of sliding, it landed safely, like a slide, the height difference was not large, and the turning slide appeared to exit in another space.

Once again, it descended smoothly in a room filled with a sponge-like substance, but it was not a standard entry position, and now the two fell together, looking not much different from the fragrant scene.

What a blessing.

Bang ——!

The beam cannon pierced the wall, the air currents in the upper floors, exchanging inside and outside, the sleeves of their clothes fluttering, and the mechanical monsters entangled in the storm stared at their prey with inorganic red pupils, and the sound of the barrel warming up sounded.

Unable to help but say, the white-haired boy picked up Chichihime and entered the 100-meter sprint state, entering another tunnel, and there was a burst of explosions behind him, and the originally dark tunnel was illuminated by the firelight of the explosion.

The light flickered ahead, and he came to a new room, and when he fell, the boy was ready, and rolled to the ground with a handsome body, reaching out his hands to catch his teammates who had separated at the exit.

Bang.

"It hurts, what do you mean by that?"

"It's nothing, it's a homeopathic action......"

Anyway, the only remedy that can be done now is to reach out and help the blonde beautiful girl, when the girl gets up, she also strokes the buttocks that hit the ground with one hand, and it seems to be red and swollen, but this is most likely an illusion.

"This is the power of the weapons of the 'Super Ancient Civilization'? If you don't run fast, you will die. ”

Bang ——!

There was a big explosion at the entrance behind him, and the shock wave caused the two people to roll together, and they only stopped when they hit the desk, and the sky was spinning, and the sound of wings sounded again, and the hair of the two people flew, and it felt like they would be mixed together if they were not careful.

"Damn, how can you chase after it?!"

Both of them chose to jump on their desks, take a limit jump, take advantage of the storm that appeared behind them again, and jump to the other desk, and the bullets that had not yet stood firm and strafed poured in, and they hurriedly dodged, like a treacherous dance step, and the robes were shot into a hornet's nest, which looked unusually trendy.

The boy chooses to use the flakes on his desk as flying props, and kicks the props continuously, turning into a galloping meteor and flying towards the bee-like machine.

Several bursts of explosive projectiles collided with flying props, forming a huge amount of smoke, and the shattered flakes turned into sharp blades, accelerating the blast wave of the explosion, slicing through the boy's skin.

"What about it, we can't use aura particles right now, why don't we try those weapons that are placed there?"

In the dust of the explosion, the two moved to the cabinets on either side of the room.

"Hopefully, they haven't rusted over time and become unusable. ”

The blonde girl, Chihime put forward a somewhat pessimistic idea, no wonder, after all, the luck of the two of them is so bad that it is estimated that it is the most unlucky day of the whole year.

"Since those monsters can move, there is no reason why the weapons will rust, I believe that the 'Super Ancient Civilization' is well maintained. ”

Zhihime, who didn't know anything about equipment, fiddled with the weapon she had taken out of the cabinet and turned the handle to know how to use it.

"Don't you have instructions or anything like that?"

Even Xue Wei, who has some knowledge of "ultra-ancient civilization", can't understand that the use of these devices is roughly equivalent to the appearance of a firearm, but where is the trigger that was pulled?

"This?"

"Thank you for being able to find the manual. ”

"It's under the device, but I can't read the text on it. ”

After receiving the manual, it was the civilization of that era, that is, the text expressed in two languages, Chinese and English, one side in Chinese and the other in English.

The strafing bullets penetrated the translucent window pane, and just as the bullets gradually approached the two people, the weapons placed in the window were placed, and the arc breeded, accompanied by a roar, like a chain reaction, a whole row of weapons were all detonated, the roar of the doji, and the thick smoke could be seen outside the high-rise building, and the power of the explosion completely destroyed the high-density walls of the building.

『Activation Command』

『open』

『Attack Command』

『attack』

『Target Locked』

『lock up』

Several sounds activate the sound effect, aiming at the target through the smoke, pulling the trigger, and the impact of electromagnetic beam-like light, the impact of bright blue tones directly penetrates a mechanical bee, and then triggers a bloated phenomenon like a large amount of inflation, and the high-temperature explosion from the inside destroys the mechanical bee from the inside out, and the nano blood infused in the mechanical body sprays out.

However, it's just one, bees are swarms of creatures, symbolizing a legion, the fire control system of the unmanned weapon quickly deduces the firing location of the beam, adjusts the muzzle, this time it's not just a demonstrative strafing, the danger level is raised to the second stage, the permission is unlocked, the box missile bombardment target is activated, and the destruction of buildings within a certain range is ignored.

Speeding missiles burst out of the ammunition box, drawing white arcs and bombarding the target site.

A series of explosions sounded, directly shaking to the upper part of the tall building, the broken wall, began to tilt, and under the continuous accumulation of shock waves, the collapse phenomenon occurred.

A special material like a plastic product falls to the ground, crushing street lamps, cutting off stranded vehicles, and bursting electricity from the broken parts of cables, like a silver snake dancing wildly.

However, with the special structure and materials of the high-rise building, the lower floors are still unharmed, and the floor where Snow Evil and Rank Ji are located for two days is very lucky to be safe and sound.

However, their luck was only that, and the intensive bombardment of missiles was destroyed into pieces and pierced into the abdomen of the white-haired boy.

And Chihime was not affected by the damage of his actions under the protection of the boy.

"Ahem! The shock wave alone makes the internal organs feel dislocated, and I don't know when I was stabbed in the abdomen, and now I pull out the fragments, it is estimated that it will accelerate death, which is really a terrible state. ”

"Who needs your protection...... Forget it, I'm ungrateful, it's better for us to flee into the building now, after all, if it's in an open environment, they have more means of attacking. ”

"No, escaping into the building is now an act of death, judging from the attack just now, those machines don't care about the damage to the building, if we are inside the building, they can directly pour a lot of fire to destroy the building, bury it alive or bombard it, and now the only escape route is underground. ”

Thinking, constantly thinking, thinking of ways to escape, vetoing one route after another, and began to think about it, didn't you just see it in the sky? The route of this city, combined with intelligence, deduced where is the road to the underground.

Add conditions, the nearest route, add a narrow space to prevent the opponent's large-scale attack.

The eyelids are getting heavier and heavier, and the abnormality caused by a large amount of blood loss is as if I have stayed up for several days, and I am full of uncomfortable feelings.

『Switching mode』

Change the way you use your weapon, hug your companion next to you, ignore her exclamations, raise your pattern-changing firearm, aim it at the tall building next door, and pull the trigger.

The emitted light was like a hook lock, sticking to the target, the boy hugged his companion and jumped down, the rope suddenly began to contract, bearing the gravity of the two, the boy felt the pain of his body as if it was about to be torn in half, reached the predetermined location, and pulled the trigger again, cutting the connection with the rope.

In the state of hugging Chihime, the injured white-haired boy barely managed to complete the body action, and a large amount of blood spilled from the wound again, and the boy quickly got up.

『Switching mode』

『Armed suppression mode』

Determine the position of a mechanical bee by the sound of its wings as it moves, turn around, pull the trigger, accurately hit the target, and solve one first.

The two of them began to run, and the bus of the obstacle was directly destroyed by the powerful impact of the firearms, and the road that was fused was now ignored by the high temperature that could be felt through the boots, because those unmanned weapons were going to sweep away the two uninvited guests with a devastating attack that did not take into account the surrounding environment.

With the burning sea of fire as the background, the two of them rushed into the alley, and the identification light of the unmanned weapon flashed above, and through the joint performance of the whole, they commanded other animal and plant types of machinery lurking around.

The white-haired and red-eyed man who noticed the anomaly reminded him.

"Get down!"

Quickly lowered his body, and turned around from the sawtooth that was supposed to break the waist of the two of them, and the wall was like water in front of its rotating sawtooth, tofu scum project? No, but the other party's attack was such a supermodel.

The mechanical creature that had not yet seen its true body severed the foundation of the building, aiming at the sawtooth behind him, and the white-haired boy chose to pull the trigger, and the two of them sprinted through the debrised alley, the explosion behind them hitting their backs.

Of course, this is also in his calculations, in the floating state, still stubbornly aiming at the road to the underground, with a beam of light to penetrate the sealed door, knocking on the door of someone else's house in a rough way.

Boom!

At the moment of entering the passage into the underground world, the salvo missile hit the entrance accurately, but after all, it was still a step slow, and could only play the role of blocking the entrance, blowing up the entrance, but unable to annihilate the invaders.

Armed with gunpowder smoke and gravel on the ground, the two entered the underground world in an embarrassed manner.

The young man, whose abdomen was still dripping blood, pulled out the medicine on his waist, and now he finally had time to breathe, opened the safety plug, and injected the translucent medicine inside into his body.

With labor pains, all the tubes of medicine were injected, and the needle-shaped container, which was no longer there, was discarded and lay on the curved wall of the black and bright tunnel.
