Infinite Doomsday Survival System

Chapter 21 Entering the Fortress
Yu Ling looked at the building in front of him, very curious, what kind of person built this?
Curiosity drove Yu Ling to approach the building and observe it more closely.

But just a few steps away, there was a gunshot from inside the building, and a bullet hit the ground, stirring up a cloud of dust.

Startled by the sudden gunshot, Yu Ling quickly stepped back and found a place to hide.

The surrounding area was very quiet, the shot just now was like a joke, nothing happened.

Yu Ling stuck out his head and looked around curiously.

But nothing was found, it was very quiet, and there was no trace of human breath.

This is strange, there is no one, and there is no movement. Where did the bullet come from?

After carefully observing the building in front of him, Yu Ling made a new discovery.

There are a row of small holes in the walls. If you don't look carefully, you won't be able to find the machine guns inside. They are very hidden. The bullets are probably bought and fired from somewhere.

And more than that, there are many things similar to forts on the wall, and the weapons inside are probably large weapons.

Yu Ling was very curious about what kind of structure it was inside.

According to her feeling, there is no one in here, so it must be self-defense, right?

Thinking this way, Yu Ling walked out, and in order to verify his thoughts, he approached the building in front of him again.

Coming to the previous position again, she swallowed a mouthful of saliva and took a step forward.

Sure enough, when this step was taken, gunshots rang out again in the fortress.

But this time Yu Ling was not so lucky. If he hadn't even avoided it, he would have been hit by a bullet.

After dodging the bullets, Yu Ling can confirm that this is an automatic fortress, and anyone who approaches will mercilessly injure it.

And I just reached the edge, just the attack of the triggered machine gun, if I continue to get closer, I guess even the fort above will also attack together.

It is really an invincible fortress. What kind of person is the owner here? He can build such a powerful fortress without any companions at all. He is simply the king of wanderers and will never rely on anyone.

Yu Ling became more and more curious. It would be great if such a convenient fortress could become his own.

In fact, Yu Ling has already taken action, walking around this fortress to see if he can find a weak point and let himself invade in one fell swoop.

According to her observation, this is an empty city, and there is no one in it. This is what her superpower told her.

That being the case, why not take this place for yourself, so that you don't have to be afraid of those monsters anymore.

With such a powerful firepower, I was afraid that I would not be able to survive in this doomsday.

After turning around the fortress, there was no gap at all except for the two gates that looked like drawbridges.

There are machine gun muzzles everywhere on the wall, and even the forts are completely empty. It is impossible to break through.

It is estimated that before touching the city wall, they will be shot into a sieve.

But even so, it didn't make Yu Ling give up.

Since the other party chose to use a fully automatic device, there must be shortcomings.

Being able to sense the enemy and execute precise strikes, there must be some mystery in it. As long as you can discover this mystery, you will be able to break through.

Yu Ling began to think about what kind of induction machine it was.

Generally speaking, most of them will use heat source perception, and then cooperate with the machine to manipulate the machine gun, so as to shoot the enemy.

In order to verify his idea, Yu Ling picked up a stone, heated it with his super power, and threw it into the attack range of the fortress.

Sure enough, after the stone entered the attack range, the machine gun fired a burst of fire until the stone shattered.

Seeing such a result, Yu Ling was very proud.

After all, it is still a machine, so it is easy to find its weak point.

But just in case, Yu Ling picked up another stone, but this time he didn't use his super power to heat it, but threw it directly.

The result was the same, another burst of machine gun fire until the stone was broken.

Seeing this, Yu Ling was stunned, and patted her small chest, feeling very grateful.

Fortunately, she was not arrogant just now, and went in directly, but did another experiment, otherwise, that stone would be her own fate.

But what should we do now, stones without temperature will also be shot, what exactly is the other party using to observe?

Yu Ling is going crazy, maybe those monsters will find here soon, and he must find a safe shelter as soon as possible to avoid those monsters.

But there is an absolutely safe place in front of you, but you just can't get in.

There is no one inside, even if there are people, they may not let themselves go in casually.

Calm down, me!The more critical it is, the more calm you need to be. If you observe carefully, you will definitely be able to find a breakthrough. As long as it is a machine, there will definitely be flaws.

After Yu Ling gradually calmed down, he began to think about the differences between the two previous experiments.

To put it differently, there are, superheated stones being continuously strafed.

The unheated stone stopped shooting after it fell to the ground.

There must be a breakthrough she wanted.

After thinking over and over again, Yu Ling seems to have caught something, maybe this is the breakthrough here.

Thinking of the result, Yu Ling no longer hesitated, and started the experiment by himself, stepping directly into the attack range of the machine gun.

This time the machine gun surprisingly did not attack.

Seeing such a result, Yu Ling also breathed a sigh of relief, further validating his own thoughts.

This is not an invincible fortress, and the induction mechanism is still flawed.

The people who built this fort probably also discovered it, so they used two induction mechanisms.

One is dynamic capture, as long as the machine does not move objects beyond a certain limit, it will trigger an attack, so just move slowly.

The other is heat source sensing, which captures the existing heat source and launches an attack.

If Yu Ling hadn't used his super power to lower the temperature around him, he wouldn't have been able to hide it from the machine.

The feather spirit, who discovered the mystery, began to slowly approach the fortress at the same speed as a snail.

In order to survive, she has to go in no matter what.

After an unknown amount of time, it was almost dark, and she finally came to the front of the fort, but was blocked by a new obstacle.

A moat that was one meter wide appeared in front of Yu Ling.

I thought it was just a river, and there was no difficulty at all.

But when she came to the river, she knew she was wrong, this is not an ordinary river.

The water inside is no longer clear water, it has been dyed light red by blood, which is very scary.

Not only that, even if Yu Ling is like this, there is no problem, and he can swim through it.

Until she saw a crocodile that was much longer than herself surfaced and sank again, she knew that it was not that simple.

That's right, how could two people use the sensing device to build only one moat at the door of their own house?

Not much to say here, from Yu Ling's impression, there is not only one crocodile, but besides the crocodile, there are some other carnivorous creatures, which are really terrifying.

Even if she has superpowers, she doesn't want to swim in a pool full of crocodiles.

Not to mention anything else, a little force might trigger the machine guns on the fence, and it would be no joke at that time.

It's not her Yu Ling's character to just give up after finally arriving here.

Since you have such a big problem, I must overcome it!

Walk along the moat until you come to the suspension bridge.

At this time, the sky was already dark, and with the faint moonlight, he looked at the suspension bridge in front of him.

Just then, there was a gunshot from above the city wall.

Yu Ling almost fell into the river, but luckily the gun was not aimed at himself.

Probably some zombies approached here and triggered the switch of the machine gun.

This is indeed the case. As night fell, the zombies became active, and more and more zombies gathered here.

For a while, there were gunshots everywhere, and there was even a roar. It is estimated that the fort was also triggered.

The roar of zombies could also be heard in the distance, which seemed very terrifying in the silent night.

But for Yu Ling, this is just an opportunity. If there are zombies attracting firepower for her, then she doesn't have to be cautious anymore, and directly rushes into the fortress in one breath.

Having made a decision, Yu Ling saw the right moment and instantly released all his abilities. He exploded with incredible jumping power and jumped the ten-meter-wide moat in one fell swoop.

A mere ten meters is a breeze for Yu Ling who has completely exploded, but the next step is the difficulty.

In addition to the ten-meter moat, there is also a ten-meter-long high power.

But so what, Yu Ling stepped on the wall, showed the knack of flying over the wall, and easily came to the top of the wall.

Standing on the high fence, Yu Ling felt lucky, fortunately there were zombies to help him attract firepower, otherwise it would not be so easy to come up.

After sighing in his heart, Yu Ling focused on the environment inside the fortress.

Standing on the wall, Yu Ling could see how thick the wall was, which gave people a very strong sense of security.

And also see clearly what looks inside the wall.

The ground here is much higher than the outside, and there are many plants, fruits and vegetables, which are very rich.

Seeing this situation, Yu Ling was a little relieved, so that he would not worry about the food problem.

Yu Ling jumped off the wall, no matter how you say it, the owner here will not set up traps inside the wall.

Besides, those plants are so lush and there is no trace of damage, so it should be fine.

She explored in this fortress with confidence, taking a few fruits from time to time to satisfy her hunger.

Soon, she came to the center of the fortress.

A very strange building stands here, not so much a house, but a shrunken fortress.

There are also holes for machine guns on the wall, and there are also things like forts on it.

But these are probably not activated, otherwise, she would not be able to stand here safely.

The door was not locked, Yu Ling walked in cautiously.
