Several of the other sentinels looked at Otto in amazement, watching him slowly fall to his knees, blood spurting from his fingers and mouth.

It took them a moment to realize that they were probably under attack, and were about to give a warning, but the "whoosh" sound sounded again, and after a few bright lights, the sentries fell in a pool of blood one after another.

Baker and Ben, who were in front of the computer, couldn't help but be dumbfounded when they watched this scene, they didn't expect that the "hummingbird" who looked like a selfie drone had such a murderous side.

To do this is actually very simple, the "Hummingbird" has two blades on its flanks, which are usually stored in the base of the fuselage, and when it needs to attack, it sticks out from the wings, and then spun at high speed and flies to the target...... The force generated by high-speed rotation is not insignificant, just like the rough teeth of a chainsaw, high-speed rotation can cut hard trees in two.

The "Hummingbird" is no exception, and if it is given enough space and distance, when it accelerates fast enough, it generates enough force to cut off a person's calf.

Of course, it doesn't make much sense to do this, what makes sense is to seal the throat with a knife as it is now.

"Head!" Baker asked suspiciously, "You don't seem to have told us that the 'Hummingbird' could do this!" ”

"I was going to tell you later!" Qin Tian replied.

Qin Tian didn't lie, the "Hummingbird" had only been equipped with the "S" unit for a few days, and Qin Tian had originally planned to train the soldiers one by one to slowly understand the "Hummingbird" and coordinate with it.

It's just that they didn't expect that the unexpected situation in front of them wouldn't allow them to wait until that moment.

However, it is also good that it can be applied much faster in real combat than in training on the training ground.

"And the people in the bunker!" Ben said.

"No problem!" Baker replied.

After operating a few times under Qin Tian's guidance just now, Baker was already familiar with the road at this time.

Then, two "hummingbirds" drilled through the perforations of the bunker, which would be more troublesome, because there were three people in the bunker, and two of them were still sleeping.

This is not to say that the "hummingbirds" cannot see them, but for the sleeping targets it is difficult to hit them in the neck without hitting the wall.

Just when Baker was hesitating, Qin Tian ordered: "Get rid of that sentry and make some noise!" ”

Baker understood, and controlled a "hummingbird" to spin and then "whoosh" past the target......

This time it was through the back of the neck, and the sentry broke his neck without even a snort.

To be exact, the neck is not broken, but a layer of flesh is attached to the front, and the head hangs on the body as if it were hanging down.

As for "making a sound", it was the blood that spurted from the sentry's neck, and it even squirted to the top of the bunker, and then flew down like rain on the other two people who were sleeping not far away.

The two of them were confused and didn't know what was going on, and they complained as they propped themselves up to check.

But as soon as they got up, the "hummingbird" spun at high speed again, and then flew towards their necks with a "whoosh".

Needless to say, the other bunker was needed, all that was needed was the matter of Baker's operation.

After these obstacles were cleared, Qin Tian waved back and ordered, "Go!" ”

"Let's go!"

……

The assault team was led by Qin Tian and Ben, and the chief stayed in the original place to organize and coordinate with Baker.

More than a dozen people swooped forward in the darkness.

In the past, they might have to worry about falling behind and going in the wrong direction, but now, they ...... Everyone receives a location signal from the Hummingbird at the right time, as well as a map.

In Ben's words, even if you close your eyes, you won't fall behind, and you won't go in the wrong direction.

This is not an exaggeration at all, because even when the eyes are closed, the virtual receiver in the eyes like a "contact lens" will still transmit the image information to the soldiers, and the soldiers only need to follow the moving points.

There was no danger along the way, except for the second lieutenant who went to the roof of the building to inspect the sentry.

In other words, this second lieutenant is still quite diligent, but it is precisely because of diligence that he is harmed...... Baker, of course, wouldn't give him a chance to inspect, and "Hummingbird" swooped down on him as soon as he opened the door and walked up to the roof.

"Rope gun!" Ben ordered.

"No!" Qin Tian stopped Ben's movements, and then ordered Baker on the walkie-talkie: "It's time to use the rope function!" ”

"No problem!" Baker replied.

"Rope function?" Ben asked.

At that moment, several slender ropes were thrown from the roof.

Ben half opened his mouth, looked at the top of the tower and then at Qin Tian, his face full of disbelief.

"That's right!" Qin Tian said: "It's the 'hummingbird' again!" ”

"Okay!" Ben whispered, "Head, I just want to know, what else does this thing do?" ”

"You'll find out soon!" As Qin Tian spoke, he tied his lock to the rope, and then firmly grasped the rope with both hands.

Then, what surprised Ben happened again, Qin Tian "whoosh" and was pulled to the roof...... And it is very intelligent, the speed goes from slow to fast, and the speed slowly decreases when it reaches the top of the building, just like making an elevator.

In this way, the process of climbing the stairs, which would have required a lot of effort and time, and in the meantime, which could have caused a sound to alarm the enemy, was completed in a matter of seconds.

Ben shook his head, then said to the soldiers beside him, "Look, Willer is going to be finished, guys! What are you still doing in a daze? ”

One by one, the soldiers "flew" to the roof.

Qin Tian brought them to the door, divided into two parts, one left and one right, to prepare for battle, and then said to the walkie-talkie: "We're ready, let's start!" ”

"Yes, head!" The chief answered.

Suddenly, there was a loud burst of gunfire around, several anti-aircraft machine guns were spewing flames into the building in the dark night, and there were even mortars, and shells were smashed into the vicinity of the building.

The movement immediately made the kidnappers in the building nervous, as if they had exploded, and the whole building was filled with the shouts of the kidnappers.

Then the kidnappers fought back.

Not surprisingly, the kidnappers just shot aimlessly into the darkness because they couldn't see anything.

Qin Tian believed that even if such an attack would be difficult to break through the fortress's defense, Weiler would still choose to move to the top.

The reason is simple, he is a cautious person.

Or it can also be said that he is a timid person, and timid people follow a saying: "Don't be afraid of 10,000, just in case!" ”

After waiting for a while, during which he also used military stabs to eliminate the two kidnappers who ran up from downstairs, Qin Tian saw that the time was almost up, so he ordered: "Do it!" ”

One by one, eighteen soldiers rushed down the staircase with their guns raised.
