I take the system Wanjie to pick up garbage

"Bang bang bang..."

Accompanied by a series of gunshots, the sixth round of zombies was also eliminated.

In this wave, there were only [-] zombies in total.

Ordinarily, it is already very strong.

However, to Liu Jiangtao, these zombies were just six bursts of shots from a level six sniper.

With the elimination of this wave of zombies, one tenth of the gathering hands were successfully upgraded.

Reporter, the seventh wave of zombies has appeared.

The seventh wave of zombies is level [-] zombies.

Facing [-] level [-] zombies, Liu Jiangtao's castle was no different from level [-] zombies.

Even if it is a continuous shooter, it can be done with one shot.

That's right, a level six sniper will automatically become a continuous shooter when he reaches level seven.

The upgrade of the spearman is very simple. You only need to burn out the bullets you carry, and you can automatically upgrade to the next stage.

Of course, the premise is that they must hit the target.

If it is shot indiscriminately, it has no effect.

At this moment, a message appeared in Liu Jiangtao's mind:
"Congratulations Commander, you have successfully upgraded the castle to level eight, and you can build a zombie factory for the production of zombies."

With a slight smile, Liu Jiangtao let out a long sigh of relief.

Finally able to build a zombie factory.

"Build a first-level zombie factory, build the zombie factory to the highest level, and after upgrading to the highest level, start upgrading other buildings without waiting for my order."

Having said that, Liu Jiangtao glanced at the black widow who was standing next to him and said:

"As long as you have enough energy, you can always upgrade in the normal order, which is the order I usually upgrade. I believe you."

Hearing Liu Jiangtao's words, the black widow turned around abruptly, saluted Liu Jiangtao respectfully, and then said seriously:
"Okay, Commander, there is a little girl to complete the upgrade task of serving the war castle."

After finishing speaking, the black widow directly operated.

Then, Liu Jiangtao saw that the zombie factory and the chariot factory had been upgraded.

Because the zombie factory has just been built, the upgrade time is very short, only one hour.

However, the chariot factory will take four days.

"By the way, Commander, since the castle has been upgraded to level eight, the Commander's new gun has also been successfully unlocked. Commander, please choose."

The moment the voice fell, Liu Jiangtao saw a row of firearms suddenly appearing in front of him.

These firearms turned out to be all sniper rifles.

Sniper rifle refers to a special rifle selected from ordinary rifles or specially designed and manufactured with high shooting accuracy, long distance and good reliability.

In the military, it is mainly used to shoot important targets of the opponent - such as commanders, vehicle drivers, machine gunners, etc.

The structure of the sniper rifle is basically the same as that of the ordinary rifle, the difference is that the sniper rifle is mostly equipped with a scope for precise aiming.

The barrel has been specially processed, and the accuracy is very high; when shooting, it is mostly semi-automatic or manual single-shot shooting.

In terms of characteristics, a sniper rifle is a high-precision rifle used to kill important single living targets at close range.

Usually equipped with optical sights or night vision sights, snipers can kill important single living targets within 600~1000m.

It has two types: non-automatic and semi-automatic.

Most of the sniper rifles currently equipped in various countries are semi-automatic, mainly firing high-power rifle bullets and special high-precision bullets.

There are also a few countries that have developed 5.56mm sniper rifles and 12.7mm long-range sniper rifles, such as the Barrett M95 12.7mm sniper rifle in the country of Sam.

The components of sniper rifles are usually carefully crafted, and some are selected from ordinary rifles.

The sniper rifle is equipped with a 4~8x fixed or variable magnification optical sight.

The mass of the whole gun is 4.5~6kg, and it uses 10~20 rounds of magazines. It has a comfortable cheek plate and grip device, and some have bipods.

Therefore, the long-distance accuracy is good, but the cost is also high.

The more famous military sniper rifles include the L42A1 of the Eagle Country, the M21 of the Sam Country, and the Dragunov CBA7.62mm sniper rifle of the Fighting Nation.

The structure of a sniper rifle is basically the same as that of an ordinary rifle, the difference is that the barrel is long, the range is long, and it is often equipped with a scope for precise aiming.

The barrel is specially processed; when shooting, it is mostly semi-automatic or manual single-shot shooting.

The scientific name of a sniper rifle is a high-precision tactical rifle. The original sniper rifle was not specially manufactured, but a relatively high-precision ordinary rifle was selected as a sniper rifle, and the earliest sniper rifle did not have optics and other auxiliary aiming devices.

The range of ordinary rifles is generally within 400 meters, while the range of sniper rifles is generally more than 800 meters.

The sniper rifle is known as a weapon that kills with one shot because of its extremely high shooting accuracy.

Now, a row of ten sniper rifles appeared in front of Liu Jiangtao, including the most classic L42A1 of the Eagle State, the M21 of the Sam State, and the Dragonov CBA7.62mm sniper rifle of the Fighting Nation State.

There are also rifles such as 98K Mauser rifle, M24 sniper rifle and so on.

There are even L115A3 sniper rifles, Barrett heavy sniper rifles, and more.

These are real killer weapons.

Because he often plays games, Liu Jiangtao still knows a lot about the firearms in games like 98K.

As the most mysterious country in the East with the strictest gun control in the entire world, let alone 98K, Liu Jiangtao has never seen even a short gun held in his hand (because those two words are prohibited, so forgive me).

If it weren't for coming here, Liu Jiangtao might never be able to touch the gun in his life.

How to do?
Look at the guns in front of you.

He doesn't know much about firearms.

Among the ten types of sniper rifles, he knows only those——

98K, M24, Barrett Heavy Sniper Rifle.

98K and M24 are the two guns that Liu Jiangtao knew when playing games.

The Mauser 98k carbine was the standard weapon of Nazi snipers in World War II.In order to avoid losing resistance after removing the scope, the gun is also equipped with a mechanical sight.

The M24 Sniper Weapon System, or M24SWS for short, is a military variant of the Remington 700 rifle.

M24 is derived from the famous Remington 700BDL rifle, and inherits the consistent advantages of Remington 700 series rifles, such as reliable locking, tight fit between the butt and the receiver, high precision, smooth lines and elegant appearance.
Barrett heavy-duty sniper rifles, in the upsurge of large-caliber sniper rifles, various weapons manufacturers, large and small, have launched various types in an endless stream.

50 or even larger caliber sniper rifles, but the sniper rifles of Barrett Firearms Manufacturing Co., Ltd. are in a near-monopoly market position.

These three sniper rifles Liu Jiangtao is familiar with, Liu Jiangtao is a little hesitant, how should he choose?

He doesn't understand sniper rifles at all.

At the same time, Liu Jiangtao had another feeling.

Among these ten sniper rifles, the best sniper rifles were not the three he knew.

"Black Widow, tell me, which of these ten sniper rifles should I choose?"
