And just when the other party was not aware of it, all of a sudden, the iron crow had flown above their heads. They would never have imagined that such a small crow would bring them a huge catastrophe from which they could never recover.

Yes, for them, they naturally would not have thought that an ordinary crow, at this time, in such a situation, would actually bring them a huge disaster, even a catastrophe. And this happens to be one of the terrible things about this iron crow!

Attacking it unprepared, so that the opponent is simply unable to defend against it. At this moment, with a terrifying and cruel aura of harvesting life, that iron crow had unknowingly come to the top of the group of guys who were actively and nervously preparing for battle! Then, the Iron Crow chose a relatively hidden position and suspended it in mid-air, and then, its lower abdomen, began to slowly open, and immediately, three automatic cannons were projected one after another!

The three automaton guns were spinning at high speed as they landed towards the ground. And in the process of rotating at high speed, its direction has also been controlled to a certain extent! Soon after, the three automaton guns, just like that, slowly descended to the ground. And before that, none of those dozens of people could find out that there was a black bird that was calculating them with suspicion!

Until, it wasn't until the three automatic cannons flew towards them that there were a few sharp-eyed guys that finally discovered the problem! Wow, shit, what the hell is this? It actually fell from the sky! However, since the three automaton were spinning at high speed at this moment, they still had difficulty making out what they were, even though they were shining with the luster of that metal.

And just when those people were panicked, they all stared at each other with their mouths open, and they were chattering in a very surprised tone to discuss what this kind of thing was, after all, their squad leader who had just come out of that underground headquarters had seen more after all. He thought of the deafening explosion just now, and the scene after that explosion, the two most important military facilities of their Qingyun Gang were all directly blown up and all disappeared mysteriously, and he already had a premonition that there must be something wrong with these three things of unknown origin!

So, after thinking of this, he shouted: "Damn, what are you looking at?" Hurry up, get down for me, get down for me! In fact, in his opinion, it is really difficult to say what these three things are. He was only a judgment based on his own guesses.

―――――――――――――――――――――――――――

As soon as his words fell, the three inexplicable guys had slowly descended to the ground! And then, immediately after, all of a sudden, the three automaton guns, having adjusted the angle of fire in the shortest possible time, immediately began to open fire!

"Da ~~~ Da ~~~~" The series of bullets shot out, with a piercing sound of breaking the air, and attacked directly towards the group of people not far away! At this time, in this situation, although a very small number of people are relatively strainable and fall down in time, however, most of the mercenaries have no time to escape!

As the dense bursts of bullets whistled towards them, the group of mercenaries fell in unison like harvested crops. One scream after another came continuously, with a kind of horror, with a kind of surprise! With a kind of helplessness and unwillingness!

The three automaton cannons, at this moment, are in a triangle, and in addition, their firing angles can be adjusted by about 60 degrees. Therefore, in such a situation, it is natural that, although there are only three automatic cannons, these three automatic cannons basically completely cover all the areas and all the angles.

―――――――――――――――――――――――――――

The duration of this type of automatic cannon is three minutes. However, in less than a minute of attack, the mercenary team of nearly 100 people had basically been completely wiped out. Although there were a dozen guys who eventually slipped through the net, just after the three automatic cannons stopped attacking, they thought that there was no problem, and they just stood up, but suddenly, another burst of fierce fire came over, and immediately, the only dozen guys who remained fell in a pool of blood.

At this time, Liu Jianfei stood halfway up the hillside outside the base, holding a telescope, and saw that the three automatic cannons fired by the iron crows were able to exert such a strong attack ability, and they couldn't help but feel very happy when they killed a team of nearly 100 people in less than a minute!

It is not only because of its perverted super strong attack ability, but also because of its high mobility and flexibility, in addition, there is another point, in fact, Liu Jianfei cares more about it, that is, after completing such an attack, he destroyed the strength of nearly 100 people at once, but he only consumed 300 gold coins! Yes, there's absolutely nothing wrong with that! The cost of an automatic cannon like this, which is clearly marked, is a hundred gold coins!

Moreover, Liu Jianfei has now figured out that it turns out that only three automatic cannons need to be laid to form a considerable killing effect! And before that, they often laid at least five automatic cannons at once! Now that I think about it, it is a great waste, and it is a great waste!

Moreover, it was only now that Liu Jianfei was pleasantly surprised to discover that it turned out that another feature of this kind of automatic cannon was that although the lethality was so huge, the target was small and not easy to find! And that's important in many cases, in many situations.

It is precisely because of such a special one, of course, that this is closely related to the chaos that this base is in. Anyway, at this moment, although such a bloody scene happened in this corner, which directly caused a team of nearly 100 people to be quickly wiped out, it did not attract the attention of other corners!

And that iron crow, at this time, in this situation, has already flown to another location, and is driving another massacre! Since in this Qingyun Gang, the squad is basically used as the basic unit, so in such a situation, under the leadership of their squad leaders who just came out of the basement not long ago, they have just been reorganized, and such a situation is undoubtedly the best opportunity for Iron Crow!

――――――――――――――――――――――――――

The Raven flew near the gathering place of the mercenaries again, and then, repeating the same trick, once again projected three automatic cannons. As a result, again, there was another frantic and dense rain of bullets......

Finally, in such a situation, the performance of the Iron Crow—to be exact, such a move of the Iron Crow, a group annihilation attack of dozens of people, or even hundreds of people, finally made the other party aware of the mystery.

Especially that one Qingyun Zhishang, after all, has extremely rich experience, otherwise, he would naturally not be able to do such a position now. Besides, after all, it has been a while since the big bang just now, and he has already recovered from the original state of enlightenment!

In such a situation, it is natural that his first priority is to find the root cause of his attack! Yes, in any case, the two most important military facilities of his own, the combat research room and the nuclear power plant, will not explode on their own, right? But what is the reason for this?

Originally, this Qingyun Zhishang thought that there must be a huge and powerful enemy combat force that came to seek revenge. Because those who do their job will actually be remembered by the enemy all the time. Therefore, in such a situation, it is actually normal to be attacked by the enemy.

And he has never taken it to heart, mainly because of his strength. It was he who used the looted wealth to continuously improve his base, which led to the strength it is now. Not to mention anything else, the successful construction of that combat research laboratory is clearly a monument!

Yes, that's clearly a monument! It is precisely because of this that Qingyun Zhishang did not hesitate to spend a lot of money to renovate and strengthen the combat research room after the construction was completed. On the one hand, from the point of view of appearance, the shape of the pyramid and the surface layer that reflects the metallic luster, all show its noble, elegant, atmospheric and magnificent side.

On the other hand, they did not hesitate to spend a lot of money to buy a large amount of black jade stone from the black market as an additive and added it to the protective layer outside the combat research room, thus greatly improving its comprehensive defense capability.

However, such a building, now, has suffered an accident and was inexplicably destroyed, how can this not make Qingyun Zhishang feel annoyed?
