Tie Qinglan actually has some concepts in her mind by now, but she is still not sure what Li Yan wants to do for the time being!

"Try this improvised version of the smoke grenade tube doesn't work!"

Li Yan took Tie Qinglan's words with a smile, and then continued to her: "Throw the battery over." ”

Tie Qinglan quickly threw the two bundled batteries over, and after Li Yan took the batteries, he simply readjusted the battery pack to ensure stability and connect the positive and negative poles of all batteries together!

After all this was done, Li Yan turned around and took off, grabbed the edge of the container with both hands, and then pulled his body up to the top of the container with a simple pull-up.

After a short second of observation, Li Yan almost determined the position of the sniper.

After all, although the light on the hillside over there was dim, the other party did not think of hiding the sniper position in the slightest.

"The straight-line distance is between two hundred and eighty meters and three hundred and thirty meters, it should be enough!"

Li Yan roughly judged the distance, then landed again, and then said to Tie Qinglan: "I'll attract his attention here, your fire cover, a distance of about three hundred meters, your gun, you can barely get it!" ”

Official data for the M4A1 says that the effective distance is about 600 meters.

But in reality, this distance is far from reaching.

According to Li Yan's own experiments, a relatively accurate effective killing distance was finally obtained.

That's between 250 and 300 meters.

When the bullet flies to this range, it can ensure sufficient penetration.

Once the distance of three hundred meters is exceeded, in a phrase that everyone on earth understands, the bullet will wilt.

The speed of flight decreases, and the penetrating force decreases as gravity begins to appear as an arcing parabola.

A series of problems such as these will cause the original lethality of the bullet to be insufficient.

In fact, strictly speaking, this is not the effective distance of the bullet.

Of course, at present, as far as the world is concerned, there is no specific standard for defining what kind of data is used to measure the effective distance.

Therefore, this thing should try not to look at the official data propaganda, it is of little significance.

Very often, at a distance of more than two hundred meters, the battle does not start.

Especially in urban street fighting, there are very few conflicts that can occur at a distance of 100 meters.

In the current situation, the easiest way is to give back to the other in the other way.

That is, get a sniper rifle and have a duel with the opposing sniper.

It's just that Li Yan and Tie Qinglan don't have sniper rifles, and they don't have anywhere to get them for the time being.

Therefore, you can only play on the spot and use local materials.

Tie Qinglan didn't need Li Yan to tell her how far the effective distance of the gun in her hand was, she knew it very well.

"Brother Yan, then be careful!"

Tie Qinglan didn't pretend to be anything, nodded directly, and then picked up the M4A1 assault rifle in his hand, ready to lock the direction of the sniper at any time, and then suppress the fire!

"Ready!"

Li Yan nodded, and then threw out one of the bundled battery packs!

The battery pack landed in the open space in front of the container, about thirty meters or so.

"Qingluan, let's light the fire!"

Li Yan smiled faintly, and then Tie Qinglan picked up the gun and locked on to the fist-sized battery pack, and then pulled the trigger!!

Bang!

The bullet hit the battery pack with precision!

Instantly, the liquid in the battery pack overflowed, and at the same time as the fire and explosion occurred due to the high temperature, billowing smoke began to pour out wildly!!

As we all know, all battery packs will explode and catch fire when they are subjected to severe impact, and release gases that are harmful to the body!

The billowing smoke is the toxic gas emitted from the combustion of the electrolyte liquid, and an adult can die if he inhales a few puffs!

However, at this moment, Li Yan didn't use this thing to kill himself.

The billowing smoke was just enough cover for him.

"It worked!"

Tie Qinglan watched it play on the spot, and the smoke bomb made from the ground was effective, and she was naturally very happy in her heart.

Of course, in addition to being happy, she also admired Li Yan's incredible creativity.

"Cover me!"

Li Yan commanded in a low voice, grabbed another "smoke bomb" in his hand and rushed out.

Tie Qinglan immediately picked up her gun and quickly shot towards the sniper's location!

Although she didn't know the exact location of the sniper, her fire suppression played a good role.

Several bullets hit the body and glass of the Humvee, and one of them accidentally hit the bipod at the front of the sniper rifle.

The bullet hit the bipod and bent it severely, and the muzzle of the sniper rifle lost its balanced support!

"Damn it!"

E's eyes were a little numb from the light of the suddenly burst battery pack smoke bomb, and now he was suppressed by Tie Qinglan's firepower and knocked out the bipod that supported the stable balance of the muzzle.

For a moment, E had an indescribable anger.

After all, his location has a good distance and concealment.

But even so, he was almost injured.

This gives E an indescribable anger.

He decided to kill the little who was in the way first!

However, when he simply picked up the sniper rifle and half-squatted on the roof of the car, trying to lock on to Tie Qinglan again, he found that Tie Qinglan had disappeared after firing a bullet in a magazine!

And just as he was searching around, behind the billowing smoke, suddenly there was a rapid gunshot.

Although the bullets did not hit him again, most of them hit the body of the Humvee.

If it weren't for the fact that the distance was a bit far, and the M4A1 was not equipped with a night vision scope, otherwise, Tie Qinglan would probably kill E when he fired the first shot!

"Damn bastard!"

E was a little hysterical, because the smoke bomb actually had an extraordinary long-lasting endurance.

Every time a TV explodes and burns, it releases a large amount of black smoke.

Therefore, even if his gun is equipped with a night vision sight, it is useless, and he can't see anything in the smoke.

Bang!!

E was a little angry, and raised his gun to lock into the smoke, which was a shot.

Regardless of whether you can take out your opponent, shoot first.

After a shot, Tie Qinglan's gunfire stopped instantly, but soon, he continued to shoot non-stop.

E was furious by the bullets that flew past his head from time to time.

But at the same time, this product also made a very fatal mistake.

His first target was Li Yan, but he inadvertently deviated.

According to normal operational standards, he should retreat and temporarily avoid the front.

After all, he, a sniper, failed to hit a single shot, and it was the best choice to start all over again.

Now he is here, but he wants to kill Tie Qinglan like a vindictive.

Obviously, E is out of control, for unknown reasons!

Just when he was going crazy and kept shooting to kill Tie Qinglan, a dagger as white as frost and snow had already slashed through the night sky like lightning!!
