About five seconds or so before the soldier fired.

That is, about three seconds after the two of them jumped off the building.

Xu Liang said to Duan Han: "It's almost!" ”

Duan Han was still stunned: "What are you doing?" ”

Xu Liang was in a hurry, he held Duan Han with one hand and operated the direction of the parachute with the other, but he couldn't even move the third hand. I had to rush to the cold and said: "The button I just gave you, press it quickly!" ”

Duan Han was still a little stunned, but he finally reacted.

Before the two of them jumped down just now, Xu Liang handed her a thing, which was a full-enveloping air refraction device she had made before. This thing, to be honest, although she made it herself, but she just wanted it for fun, and she didn't expect this thing to be brought by Xu Liang.

So now the question is, what's the use of this thing?

However, looking at Boss Xu's anxious look......

Okay, then press it.

Duan Han's fingers moved and pressed it.

The moment she pressed it, she heard a loud "bang" in her ears!

Duan Han still wondered: I didn't make such a big startup sound for this small device at the time!

And then she reacted!

Where is this "bang" sound effect, it's a gunshot!

Only gunfire can be so loud! So loud!

Then the question arises, the gunshots are so loud, the distance is so close, but they don't hit them, what's going on?

Could it be that this all-encompassing air refractor device is trying to make a type?

In the space of a dozen seconds, the situation changed dizzyingly. First of all, Xu Liang and Duanhan ran from the fourth floor to the sixth floor, then went to the roof, and then left safely through a parachute and an air jet. Behind them had been closely followed by military troops, but every step was just right for Xu Liang to calculate.

Until finally the GI opened fire. But this possibility was still calculated by Xu Liang, so Duan Han turned on the air refraction device in advance and was able to escape.

The principle of the all-encompassing air refractor is very simple: the refractive index of the surrounding air is changed through continuous vibration and regular heat release. This kind of physical phenomenon is very conspicuous in ordinary life, for example, when you look at the air above the flame with a lighter, the scenery will distort and show irregular changes, the reason is that the refractive index of the air after heating changes, and similarly, if you observe the path of car exhaust and the like, there will be a similar phenomenon.

The trial suit was made using this principle, but in a more ingenious way to make the refraction angle larger!

The biggest purpose of this device is to disrupt the line of sight!

And now from the actual use effect, it is very good!

Even the battle-hardened soldiers failed to hit the parachute!

When the veteran reacted and shot again, Xu Liang and the two flew out a long way again. And unsurprisingly, this second shot missed again!

Again, a small spark burst out from the telephone pole in the distance, but the parachute of Xu Liang and the two in the distance was still intact.

The veteran looked carefully into the distance and did not immediately fire a third shot.

Obviously, there is something strange about this parachute. Obviously, the two shots that were bound to be hit were aimed at before, and when they fired, they all hit the telephone pole on the right side. He didn't know what caused the phenomenon, but he had already planned how to deal with it.

Whether it's the wind factor, the light factor, or something else. Both shots had a fixed angular offset, and the angle of deflection was about ...... 7 degrees!

Then, it's good to take this offset into account in advance when aiming.

By this time, the parachute had descended to the height of a three-story building, and the distance in a straight line had reached forty meters, and it became very difficult to aim. But the veteran was not flustered, and after making serious preparations, he raised his gun and took aim. The muzzle of the gun is pointed at a small angle to the left of the parachute. There is the glass window of a residential building......

A second later, he pressed the trigger again!

"Bang, la, la!"

There was a loud bang!

The broken glass of the house was shattered!

The parachute is intact!

The veteran was stunned again!

This time, he really didn't know why he still couldn't hit!

Under the umbrella.

Duan Han: "Why did you let me turn off the device again?" ”

Xu Liang is unfathomable: "Fiction is real, reality is virtual, fiction is real, and the way of the art of war is also ......"

……

Even though the veteran was calm and came up with various coping strategies, he still didn't hit Xu Liang. He had no choice but to report to the army commander at the main entrance. At this time, the army commander had already sent a squad to chase after Xu Liang where he fled.

His strategic intentions are clear. Regardless of whether the veteran upstairs can hit the target or not, he must send someone to find someone over there, to see people alive and dead to see corpses.

This time, the army commander came with a clear combat intent from his superiors!

The so-called "martial law" is just an indicator for outsiders to see!

The real order he received was: completely seal down the research institute, and not let anyone have access to any scientific research equipment, and anyone who may use scientific research equipment can be detained by him if it is possible to contact and use it! Even kill!

This is also the reason why he dared to arrest the highly respected Academician Xu. Even, if Academician Xu is not a respected academician, he may have become a corpse.

The indifferent army commander did not hesitate to carry out the orders of his superiors. Because he clearly knows that this is no longer as simple as a military operation. Even actions that matter the life and death of the country and mankind!

Behind these commands is a logic that follows:

No information can be allowed to flow out of scientific institutions!

Do whatever it takes!

Therefore, although the army commander still seems calm on the surface, he is already a little anxious in his heart.

Because those two people are the two people who escaped by parachute with propulsion devices, that is, the two people who pretended to be Academician Xu in the large laboratory on the fourth floor that the thin security guard reported to him just now, it is likely that they are carrying relevant important information!

And this is also absolutely forbidden by this mission he carried out!

The more the army commander thought about it, the more uneasy he became. He used the walkie-talkie again to remove a ten-person team from the compound and expand the search in the direction where Xu Liang Duanhan left.

Now he has realized that these two people are definitely not ordinary people.

Those who can use a parachute in a big city, who dare to parachute from the height of a six-story building (a six-story parachute usually falls to their death), who can think of and implement a powered parachute, can also have the courage to think of the importance of scientific research in such a short period of time...... These factors add up at the same time, and it is definitely not ordinary people who can think of all this!

……

The army is known for its efficiency.

The two ten-man teams that had been sent out to search for Xu Liang's traces soon returned.

When they came back, they didn't bring back Xu Liang and Duan Han, but they brought back a small parachute that had been punctured by a tree branch, and there was a propulsion device on it.

"Captain......

The army commander said coldly: "What about people? ”

"Report to the captain! No one caught ......"

The army commander said anxiously: "Why didn't you catch it?" Why come back? Why not keep catching? ”

"No, we found this ...... next to the parachute"

The squad leader in charge of the search looked confused and handed over a small note.

The army commander took the small note, and after reading it, his face turned pale.

The note was small with a short line of words:

"Marksmanship is not accurate! Practice again? ”
