I take the system Wanjie to pick up garbage

"Congratulations, Commander, you have repelled two zombie sieges in a short period of time and won a special reward - a golden gift bag. Please check it in time, Commander."

Oh?
Diamond spree?
A trace of excitement flashed across Liu Jiangtao's face.

Another big gift bag.

What's the matter today?
The tone is so against the heavens?

Of course, Liu Jiangtao figured it out in an instant.

This is also myself.

It was only after getting three big gift packages that it succeeded.

Even, if there is no third big gift bag and the fifth-level city wall, Liu Jiangtao may even fail in the second wave.

It can be said that Liu Jiangtao's success is very accidental.

It is precisely because of this that the rewards are so generous.

A golden spree.

Just don't know how powerful it will be.

"Open the golden gift bag."

"Congratulations, Commander, you got a random soldier—month card."

"After using this random arm monthly card, within 30 days, the commander can get a random level, random arm, random number of soldiers or chariots, zombies, etc. every day."

Forehead?
Looking at the above information, Liu Jiangtao almost drooled.

Pretty.

beautiful.

It turned out to be a random type of arms, or a random level of arms.

Random arms, and nothing.

At most, there are some zombies.

However, if it is not scaled, it will not be of great use.

However, the level immediately became terrifying.

Especially at the very beginning, in the introduction, Liu Jiangtao knew that conventional arms such as shield soldiers, spearmen, and chariots were divided into ten levels, while zombies were divided into six levels.

Now Liu Jiangtao can only produce first-level and second-level conventional arms.

But with this monthly card with random arms and random levels, it's amazing.

Although there may be soldiers of the first level, as long as the soldiers of the tenth level appear once, they will earn money.

Of course, Liu Jiangtao did not believe that there would be a large number of first-level soldiers in the soldier cards opened in the golden gift package.

Just as Liu Jiangtao was meditating, there was a low roar from outside the city wall.

Looking outside with disbelief, I saw [-] zombies moving slowly towards the city wall.

Seeing this scene, Liu Jiangtao subconsciously picked up the golden AK47.
The gun had thirty rounds of life remaining.

The total number of bullets that firearms can fire under the specified test and operating conditions to ensure that they meet the tactical and technical requirements.

Also known as firearm shooting life.

Firearm life includes shooting life and operating life.

The shooting life of firearms is determined by live ammunition shooting under the specified shooting specification conditions and according to the specified shooting method.

Generally, one of the following three conditions is used as the criterion for determining the end of life:
The failure rate exceeds the tactical technical index or an unacceptable failure occurs.

The main parts of firearms, such as barrels, receivers, bolts, receivers, triggers, gun mounts, etc., are not worth repairing due to cracks, damage, deformation visible to the human eye, loss of working ability or high maintenance costs.

Ballistic performance of the barrel is reduced more than allowed.

The shooting life refers to the maximum number of projectiles that the various performances of the gun can meet the requirements of the indicators in the life test, that is, the highest life level that the sample gun can achieve.

Any kind of firearms must undergo a life test in the development stage of its new gun, that is, to carry out live ammunition shooting through the prescribed operating procedures, and then verify the number of projectiles of the gun.

This kind of test is an extremely strict assessment that determines the success or failure of the development of a new gun. If the requirements cannot be met and the indicators cannot be modified, it must be redeveloped.

Generally speaking, the shooting life is generally 2 to 3 times higher than the design life or even higher.For example, the shooting life of a medium-sized short gun can reach 6000 to 10000 rounds.

The service life refers to the cumulative number of projectiles under actual combat conditions regardless of the shooting method.

This lifespan is not only related to combat training conditions, but also related to the maintenance of the gun by the user.

Usually used in harsh environments or in fierce battles, the service life is shorter; under the same combat training conditions, with careful maintenance, the service life may be longer.

The life data of the same type of firearms must be compared under the same test environment and with the same end-of-life criterion and shooting specification.

If the design life of a short gun is 3000 rounds, it must be guaranteed to reliably fire 000 rounds under high temperature, low temperature, and normal temperature conditions during the life test.

In addition, it is also necessary to determine the damage of the firearm, such as the movement, machine frame, casing and barrel, and whether the ballistic performance has declined, so that the gun cannot meet the combat requirements.

Then again, the life of a firearm is not as high as possible.There is another important prerequisite for determining the life of a firearm, that is, its power, reliability, mobility, economy and ease of use must be considered.

If there are parts, some parts can be replaced to increase the service life of the firearm.

However, this is for those who are able.

For Liu Jiangtao, he still can't do it.

No way, immortal professional.

He can only say that the concubine can't do it.

When Liu Jiangtao looked outside, he suddenly saw that the zombies in his sight turned out to be green representing his side, not red representing hostility, and white representing the neutral side, that is, wild monsters.

This special meow is his own zombie?

At the same moment, Liu Jiangtao also remembered a piece of news:
"Congratulations Commander, you have successfully obtained Level 500 Giant Zombie*[-]."

That's right, it was five hundred giant zombies.

Looking at these zombies, Liu Jiangtao's saliva really flowed out.

The five hundred and three-level giant zombies are more powerful than the five thousand five-level shield soldiers.

Moreover, after being attacked by giant zombies, there is a certain possibility of turning into zombies.

"pretty."

……

For the next three days, Liu Jiangtao basically didn't sleep much, and he was working hard to upgrade the building.

In three days, Liu Jiangtao has upgraded the castle to level five.

Level [-] castles, level [-] chariot factories, level [-] spear arsenals, level [-] shield arsenals, and of course, level [-] energy collectors.

Even, the current castle is being upgraded to a level six castle.

Without these energy sources, it is absolutely impossible for Liu Jiangtao's castle to upgrade so quickly.

At the same time, during these three days, Liu Jiangtao has been training soldiers day and night.

The fifth-level arsenal can accommodate [-] soldiers.

When upgrading, it takes one hour to level two, two hours to level two to level three, four hours to level three to level four, and eight hours to level four to level five.

It took Liu Jiangtao eighteen hours to upgrade the castle.

Fortunately, Liu Jiangtao has enough energy and also has a second construction team. Otherwise, Liu Jiangtao would definitely not be able to upgrade the castle to level five in such a short period of time.

In three days, Liu Jiangtao also accumulated a total of [-] soldiers.
