The familiar sound of the system, it has been three years since Tianlan came to this apocalyptic world.

And in the past three years, this voice has not been heard, and today the system finally speaks again.

Tianlan will inevitably be a little excited, after all, the system has a lot of secrets, and after years of research, he has only discovered the skin.

If there is a system to help, then many things will become clear.

"System, what does it mean to raise the level to one?" He was the first to ask about the ranks.

This was the first time he had heard of a level, and although he could gain experience from seeing the mission, he didn't know what the experience was for.

[Answer: The level refers to the system level, and the higher the level, the higher the authority. 】

"Permissions?" Tianlan pondered for a moment and asked, "What's the use of permissions?" What can I do with my current permissions? ”

[Can let the host know more things and redeem more prizes.] Now that the system level is one, open the system voice program, and the things you can get are as follows. 】

Immediately after, a list-like thing appeared in Tianlan's sight.

There's a lot of stuff in it, and it's all expensive, and it's very valuable.

But the exchange bar is black, and it is obvious that these things cannot be exchanged according to their current permissions.

"Only items that I am able to redeem right now."

Under Tianlan's voice, the basket frame changed, the black things that could not be exchanged disappeared, and the things that could be exchanged were revealed.

Looking at the things in the bar, Tianlan had a general understanding in her heart.

It is true that everything can be exchanged, from guns and cannons to even superpowers.

The cheapest thing is food and water, and of course some clothing.

In the end, those don't have any effect on the current Tianlan, and if you want clothes, you can go to the city if you want, and the same goes for food and water.

Then what can come in handy is superpowers, as well as guns and cannons, but the price of these is very high.

Tianlan, who continued to browse, noticed another thing and asked, "Why is this thing full of permissions, but it can't be exchanged?" ”

[In order to balance the doomsday benchmark, things that do not belong to this world cannot be exchanged.] 】

"That means this thing is going to appear."

[Yes.] 】

After getting the answer of the system, Tianlan was sure that in the end of the future, there would be a gundam.

But in this case, there is another question, what is the situation of superpowers.

Is it exclusive to this world, or is it common to all worlds?

[Superpower is a supernatural phenomenon that has existed in the original world, and it is one of the universal abilities in the world. 】

"Yes." Tianlan asked again: "What is the difference between the superpowers obtained in the zombie apocalypse and the superpowers exchanged in the system?" ”

[There is no difference, the biggest difference is probably that the system can still use it in the next apocalyptic scene, and the superpowers obtained by abnormal means in the apocalypse cannot be used. 】

Sure enough, with a system, it's different, and you can understand a lot of things.

If you don't know this, you may suffer a big loss at that time.

Tian Lan looked at her gold coin quota that was still negative, and couldn't help but feel a little uncomfortable in her heart.

At the beginning of the game, I used up three hundred gold coins at the beginning, and I still owed seven hundred.

Now in the past three years, I have completed large and small tasks and achievements, but I still owe two hundred and five gold coins.

Oh no, it should be one hundred and fifteen, and at the moment when his home was completed, there was a hundred gold coins in the account.

But when will it be over?

"System, do you know any way to earn gold?"

[Ding-dong!] Complete quests and achieve achievements to get a lot of gold. 】

This Tianlan thinks that it probably can't work, and the reward for the task is only five or ten gold coins, and the most is the task of this family, but it is only a hundred gold coins.

[Tasks and achievements can be obtained in the later stage, and a large number of gold coins can be obtained.] 】

【Ding Dong!】 The time has come to force the mission to launch and test your own home. Survive a wave of zombies, quest rewards, and 300 gold coins. 】

Hey, this beep, don't say it, it's pretty easy to use.

If there is a new task, it will be reminded, so that is, when the task is completed, it will also remind yourself, so that you can save a lot of trouble of viewing.

But now this mandatory task, that is, near me, there is a large wave of zombies approaching.

But in the past three years, the surrounding zombies have been almost cleaned up by Tianlan, and there will be so many zombies there?

Now is not the time to think so much, it's time to prepare.

"What is the number of mission zombies?"

[The number of zombies is 1,000, please concentrate on completing the task.] 】

Hearing the system's answer, Tianlan felt that the system was even more convenient, and even the number of zombies could be clear.

Then it's time to show the strength of your home.

Tianlan took out a remote control from her pocket and pressed the button to turn it on.

It's a bit immature, but it's also an automatic defense system that I made with my own efforts.

Using infrared perception, you can accurately hit the approaching zombies.

It's just that the hit rate is a bit low, but in the face of hordes of zombies, it can come in handy.

Carrying her own small bench, Tianlan sat on the roof and watched the distance.

Of course, it's not just a lookout standing at the top, but a sniper rifle is placed on it, which is specially used to snipe zombies in the distance.

Barrett, this is the only gun Tianlan knows.

Its power is so great that it can easily shoot the head of a second-level zombie, which is completely expensive.

Sure enough, the zombies in the distance began to gather, and Tianlan looked at the number of people displayed by the system.

The number of people here is not the number of zombies in front of them, but the number of zombies left in the world, and the number of human survivors.

The number of living people has recently begun to stabilize after an initial period of extreme decay.

The number of survivors is stable at 500 million, and there are people who die every day, and babies are born, just forming a delicate balance.

The zombies are different, and the number will increase from time to time, but they can't keep up with the speed of decay at all.

In just three years, it has decayed to about 5 billion. It's still decreasing.

But for some reason, the decay rate of zombies has slowed down a lot lately.

I don't know why, but I can guess a little.

In the first-level apocalyptic world, there are only first-level zombies and second-level zombies, so that is to say, the zombies left behind now are basically second-level zombies.

It's also possible that the level of Doomsday is rising, and maybe the third-level zombies have also appeared.

Tianlan shook her head, now is not the time to think about other things, the most important thing is to focus on the things in front of you first.

Take out Barrett from the box and aim for the zombie horde thousands of miles away.

Maybe Tianlan's shooting accuracy is not good now, but the number of opponents is large, and he can hit zombies with any shot.

Boom! Tian Lan fired a shot, and the strong recoil did not do anything for his current chances.

Three years of brick life have greatly improved his physical ability, and even his skin has tanned a lot.

A shot hits, and a zombie is shot in the shoulder.

Although he didn't hit the head, Barrett was so powerful that even if it was just a blow to the shoulder, the zombie's head was shattered by the powerful impact.

Seeing a zombie killed, Tianlan looked at the number provided by the system.

The number of zombies has been reduced by one.

In other words, this group of zombies was not specially created by the system for the purpose of creating tasks.

In other words, as long as you are willing to work hard, you can kill all the zombies first, including humans, and end this apocalypse ahead of schedule.

There is no need to go through any second-level apocalypse, tertiary apocalypse, or something.

Tianlan, who thought about it like this, felt that this was very feasible.

When you have time, find a place to store nuclear bombs, and take a click or two in the place with the highest concentration of zombies, and maybe tens of millions of zombies or humans will disappear.

Tianlan, who made such a decision, began to practice his marksmanship with this group of zombies.

I don't want a shot for a child, but I want to have a bullet without missing a shot.

The number of zombies gradually decreased under Tianlan's sniping, and the first-level zombies that moved slowly were eliminated by Tianlan one by one.

Among the thousand zombies, more than fifty of them are second-level zombies.

Unlike the first-level zombies, they moved very quickly, and Tianlan couldn't hit them at all.

Soon they came to the first line of defense of their fortifications, infrared automatically scanning the range of attack of the machine guns.

Among them, the second-level zombies who acted clumsy were quickly shot into a sieve.

And those second-level zombies with enhanced speed easily dodged the strafing of machine guns and came to the second line of defense, a moat ten meters wide.

Standing by the river, some zombies jumped regardless of the danger.

However, they overestimated themselves and after jumping five meters away, they fell into the river.

The crocodiles and big catfish in the river saw the fallen zombies, and they were already hungry and thirsty, so they pounced on them directly, and a zombie was torn to pieces and devoured.

And the zombies who stood by the river and hesitated, began to endure machine gun fire while circling around the river, observing whether they could find the assault point.

The reality is desperate, how could Tianlan be so careless to leave them a breakthrough point.

The place where you cross the road is the suspension bridge structure, and Tianlan will not put down the suspension bridge until you travel.

And the width of the moat, no matter where it is, will only be wide and not narrow, and it is not at all the distance they can jump over.

Soon, the zombies could not withstand the machine-gun fire and fell to the ground.

Those slow-moving first-level zombies in the distance, Tianlan also lost interest in them, and let them come here if they wanted to.

The moment they stepped into the range of the machine-gun attack, they were shot mercilessly.

【Ding Dong!】 Mandatory task completion, get 300 gold coins, 300 experience, the current gold coin limit is 150, please cherish it. 】

The mandatory task was successfully completed, and now Tianlan has finally gotten rid of the negative gold coins.

The mood is rare and happy.

At this time, several figures appeared in the distance, rushing towards Tianlan's side.

Judging by their situation, they shouldn't be zombies.
