Infinite Doomsday Survival System

Chapter 14 Mandatory Tasks
Familiar system sounds, three years have passed since Tian Lan came to this apocalyptic world.

In the past three years, this voice has not been heard. Today, the system finally spoke again.

Tian Lan will inevitably be a little excited. After all, the system has many secrets. After years of research, he has only discovered the superficial.

If there is system assistance, many things will become clear.

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

This was the first time he heard that there was a level. Although he could gain experience after seeing the mission, he didn't know what the experience was used for.

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

"Permission?" Tian Lan asked after pondering for a while, "What's the use of permission? What can my current permission do for me?"

[You can let the host know more things and redeem more prizes.Now that the system level is one, if you open the system voice program, you can get the following things. 】

Then, something like a list appeared in Tian Lan's sight.

There are many things in it, and they are very expensive, and the value is also very large.

But the exchange column is black. Obviously these things cannot be exchanged according to my current authority.

"Only showing items I can redeem now."

Under Tian Lan's voice, the basket changed, the black items that could not be exchanged disappeared, and the items that could be exchanged appeared.

Looking at the items in the column, Tian Lan had a general understanding in her heart.

Everything can be redeemed here, from guns and cannons to even superpowers.

The cheapest is food and water, and of course some clothes.

The last ones will have no effect on Tian Lan now. If you want clothes, go to the city. The same goes for food and water.

Then the things that can come in handy are superpowers and guns and cannons, but the prices of these are very high.

Tian Lan, who continued to browse, noticed something else and asked: "Why can't this thing be redeemed even though it has enough permissions?"

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

"That means, this thing will appear."

【Yes. 】

After receiving the system's answer, Tian Lan confirmed that there will be Gundams in the apocalypse.

But if this is the case, then there is another question, what is the super power?

Is it an exclusive exchange for this world, or is it common for all worlds?
[Super power is a supernatural phenomenon that the world already possesses, and it is one of the common abilities in the world. 】

"Really." Tian Lan asked again: "Then what is the difference between the super powers obtained in the zombie apocalypse and the super powers exchanged in the system?"

[There is no difference. The biggest difference is probably that the items redeemed by the system can still be used in the next doomsday scene, but the superpowers obtained through abnormal means in the apocalypse cannot be used. 】

Sure enough, having a system is different, and you can understand many things.

If you don't know this, you may suffer a big loss by then.

Looking at her gold coin amount which was still negative, Tian Lan couldn't help but feel a little uncomfortable.

He used up the [-] gold coins at the beginning, and he still owed [-] gold coins.

Now, in the past three years, he has completed large and small tasks and achieved achievements, but he still owes two hundred and five gold coins.

Oh no, it should be one hundred and fifty. The moment his home was completed, he received one hundred gold coins.

But when will this be over?

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

[Ding dong!Complete tasks and achieve achievements to get a lot of gold coins. 】

This Tianlan thinks it is probably not possible. The reward for the task is only five or ten gold coins. The most is the task of this family, but it is only one hundred gold coins.

[In the later stages of tasks and achievements, you can get a lot of gold coins. 】

[Ding dong!The mandatory mission is launched, and it's time to test your own home.Survive a wave of zombies, mission reward, three hundred gold coins. 】

Hey, this notification sound, not to mention, is very useful.

It will remind you when there are new tasks, that is to say, when you complete the task, you will also be reminded, so that you can save a lot of trouble of checking.

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

But in the past three years, the surrounding zombies have been almost cleaned up by Tian Lan, where will there be so many zombies?
Now is not the time to think so much, it is time to prepare.

"How many zombies are there in the mission?"

[The number of zombies is one thousand, please concentrate on completing the mission. 】

Hearing the system's answer, Tian Lan felt that the system was more convenient, even the number of zombies could be clearly seen.

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

Tian Lan took out a remote control from his pocket and pressed the button to turn it on.

Although it is a bit immature, this is an automatic defense system that I personally made with my best efforts.

Using infrared sensing, you can accurately attack approaching zombies.

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

Moving her own small bench, Tian Lan sat on the roof, watching the distance.

Of course, standing on the highest point is not just looking out, but there are sniper rifles on it, which are specially used to snipe zombies in the distance.

Barrett, this is probably the only gun Tianlan knows.

Its power is so great that it can easily blow the head of a second-level zombie, which is a lot of effort.

Sure enough, the zombies in the distance began to gather, Tian Lan looked at the number 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.

After an initial extreme decline, the number of living people has recently begun to stabilize.

The number of survivors is stable at [-] million. Every day, people will be sacrificed and babies will be born. It just forms a delicate balance.

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

In just three years, it has declined to about 50 billion.It is still decreasing now.

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

Although I don't know the reasons, I can roughly guess some of them.

The first-level doomsday world is only composed of first-level zombies and second-level zombies. In other words, the remaining zombies are basically second-level zombies.

It is also possible that the level of doomsday is increasing, and maybe level three zombies have also appeared.

Tian Lan 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 her.

Take out the Barrett in the box and aim at the zombie group thousands of meters away.

Maybe Tian Lan's shooting accuracy is not good now, but there are so many opponents that he can hit zombies with just one shot.

Boom!Tian Lan fired a shot, and the strong recoil had no effect on his current chance.

Three years of living in bricks has greatly improved his physical ability, and even his skin has been tanned a lot.

With one shot, a zombie was hit in the shoulder.

Although it didn't hit the head, Barrett's powerful force, even if it only hit the shoulder, the zombie's head was crushed by the powerful impact.

Seeing a zombie being killed, Tian Lan looked at the number provided by the system.

The number of zombies decreased by one.

In other words, these zombies were not specially created by the system to create missions.

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

There is no need to experience the second level apocalypse, the third level apocalypse, or anything like that.

Thinking of this, Tian Lan felt that this was very feasible.

If you have time, find a place to store nuclear bombs, and hit the place with the highest concentration of zombies. Maybe tens of millions of zombies or humans will disappear.

Having made this decision, Tian Lan began to practice his own marksmanship with the zombies.

Don't ask for a shot and a child, but ask for the perfect shot.

The number of zombies gradually decreased under Tian Lan's sniping, and the slow-moving first-level zombies were wiped out one by one by Tian Lan.

Out of a thousand zombies, more than 50 of them are second-level zombies.

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

Soon they came to the first line of defense they fortified, the infrared automatic scanning machine gun's attack range.

Among them, the clumsy second-level zombies were quickly shot into pieces.

The second-level zombies with enhanced speed easily escaped the machine gun fire and reached the second line of defense, the ten-meter-wide moat.

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

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

When the crocodiles and giant catfish in the river saw the fallen zombies, they were already hungry and thirsty, so they pounced on them and one of the zombies was torn into pieces and swallowed.

And those zombies who stood hesitant by the river began to walk around the river while bearing the machine gun fire, to see if they could find an assault point.

The reality is very desperate, how could Tian Lan leave them a breakthrough point so carelessly.

The crossing area is a suspension bridge structure. Tianlan will not lower the suspension bridge until it is time to travel.

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

Soon, these zombies couldn't stand the machine gun fire and fell to the ground.

Tian Lan also lost interest in those slow-moving first-level zombies in the distance, and let them come here.

The moment they stepped into the range of the machine gun attack, they were shot down without mercy.

[Ding dong!Compulsory tasks are completed, and you can get 150 gold coins and [-] experience. The current gold coin limit is [-], please cherish it. 】

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

Feeling very happy.

At this time, several figures appeared in the distance, rushing towards Tian Lan.

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