Yu Ling looked at the building in front of him and was very curious, what kind of person built it?

Curiosity drove the Feather Spirit to approach the building and take a closer look at it.

But just a few steps away, a gunshot was heard from inside the building, and a bullet hit the ground, kicking up a wisp of dust.

Feather Ling, who was startled by the sudden gunshot, hurriedly retreated and found a place to hide.

It was very quiet, and the shot was like a joke, and nothing was happening.

Feather Spirit poked out his head and looked around curiously.

But nothing was found, it was very quiet, there was not a trace of human breath.

It's weird, there's no person, there's no movement, where the hell did the bullet come from?

Carefully observing the feather spirit of the building in front of him, he made a new discovery.

There are rows of small holes in those walls, if you don't look closely, you can't find the machine guns inside, they are very hidden, and the bullets are probably bought and fired from.

And that's not all, there are a lot of things on the wall that resemble a gun emplacement, and there are probably large weapons in them.

What kind of structure is inside, Yu Ling is very curious about this.

According to her senses, there is no one in this, so it can't be self-defense, right?

Yu Ling, who was thinking like this, walked out, and in order to verify his thoughts, he approached the building in front of him again.

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

Sure enough, when this step was taken, gunfire rang out again from the fortress.

However, this time the feather spirit was not so lucky, if it hadn't been dodged, it was estimated that he would have been hit by a bullet.

After dodging the bullets, Feather Spirit can confirm that this is an automatic fortress, but anything that comes close will mercilessly damage it.

And I'm just on the edge, and it's just a machine gun attack, and if I keep getting closer, I guess even the turret above will attack together.

It's really an invincible fortress, what kind of person is the master here, he can build such a powerful fortress, he doesn't need any companions at all, he is simply the king of wanderers, and he will definitely not rely on anyone.

Yu Ling became more and more curious, such a convenient fortress, if it could be its own thing, how good it would be.

In fact, the Feather Spirit had already made a move and walked around the fortress to see if he could find a weak spot and allow himself to invade it in one fell swoop.

According to her observations, it was an empty city, and there was no one in it at all, which was what her superpowers told her.

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

With such powerful firepower, I am afraid that I will not survive in this apocalypse.

After going around the fortress, there was not a single gap except for the two drawbridge-like gates.

The walls are full of machine guns, and even the batteries are unavailable, so it won't work to break in.

It is estimated that before the city wall is touched, it will be swept into a sieve.

But even this did not make Yu Ling give up.

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

There must be some mystery in being able to sense the enemy and deliver an unmistakable strike, as long as you can discover this mystery, it is a gap to break through.

Feather Spirit began to wonder what kind of induction machine it was.

Generally speaking, most will use heat sensing and then work with a machine gun to strafe enemies.

In order to test his thoughts, Feather Spirit picked up a stone, heated it up with his superpowers, and threw it into the attack range of the fortress.

Sure enough, after the stone came into range, the machine gun fired a flurry of fire until the stone shattered.

Seeing such a result, Yu Ling was very proud.

After all, it's still a machine, so it's easy to find weaknesses.

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

The result was the same, another burst of machine-gun fire until the stones shattered.

Seeing this, Yu Ling was stunned, patted his little chest, and was very happy in his heart.

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

But what to do now, stones without temperature will also be strafed, what is the other party using to observe?

The feather spirits are going crazy, maybe those monsters will find this place soon, and they must find a safe shelter to avoid those monsters as soon as possible.

But there's a safe place in front of you, but you just can't get in.

There's no one in there, and even if there are, they won't necessarily let themselves in casually.

Calm down, me! The more crisis, the more calm and careful observation will definitely be able to find a breakthrough, as long as it is mechanical, then there will be a flaw.

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

If anything, there is, and the overheated stones are continuously strafed.

And the unheated stones, after falling to the ground, stopped strafing.

There must be a breakthrough in this that she wants.

After thinking about it repeatedly, Yu Ling seemed to have caught something, maybe this was the breakthrough here.

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

This time the machine guns were surprisingly not attacking.

Seeing such a result, Yu Ling also breathed a sigh of relief and confirmed his thoughts even more.

It's not an invincible fortress, and the induction machinery is flawed.

The person who built the fort probably found out as well, so two kinds of induction machines were used.

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

The other is heat sensing, which captures the heat source that exists and attacks it.

If it weren't for the fact that Yu Ling used his superpower to lower the temperature around him, he might not be able to hide from the machine.

The feather spirit, which had discovered the mystery, began to use the same speed as a snail, slowly approaching the fortress.

In order to survive, she said that she would go in for anything.

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

A moat that was 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 that she was wrong, this was an ordinary river.

The water inside is no longer clear water, it has been dyed a faint red by blood, which is very terrifying.

Not only that, originally the feather spirit was even like this, there was no problem, and it was completely possible to swim over.

It wasn't until she saw a crocodile that was not much longer than herself surfaced and sank down again, that she knew it wasn't that simple.

It's also true, how can a person who uses two sensors build only one moat at his own door?

Not much to say here, from the sense of the feather spirit, there is more than one crocodile, and in addition to the crocodile, there are some other carnivorous creatures, which is really terrifying.

Even if she had superpowers, she didn't want to swim in this pool full of crocodiles.

Not to mention anything else, with a little force, you might be able to trigger the machine gun on the wall, and then it won't be a joke.

Finally got here, just give up like this, this is not her Yu Ling's character.

Since you've got such a big problem, I'm going to have to overcome it!

Walking along the moat, we came to the drawbridge.

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

At this moment, a gunshot rang out from above the city walls.

Yu Ling almost fell into the river, but fortunately the muzzle of the gun was not aimed at him.

Probably a zombie approached here and triggered the switch of the machine gun.

Indeed, as night fell, the zombies began to become active, and more and more zombies gathered here.

For a while, there were gunshots everywhere, and there was even a roar, presumably the battery was also triggered.

The roar of zombies was also heard in the distance, and in the silence of the night, it looked very terrifying.

But this is an opportunity for Yu Ling, there are zombies attracting firepower for her, so she doesn't have to be cautious anymore, and directly rush into this fortress in one go.

Yu Ling, who had made a decision, saw the opportunity and instantly released all his abilities, bursting out with unbelievable bouncing power, jumping over the ten-meter-wide moat in one fell swoop.

It's only ten meters, it's easy for the feather spirit that has completely exploded, but then it's the difficulty.

In addition to a ten-meter moat, there is also a ten-meter high strength.

But so what, Yu Ling stepped on the wall, showed the trick of flying eaves and walls, and easily came to the top of the wall.

When standing on the high wall, Yu Ling was glad in his heart, 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 his attention on the environment inside this fortress.

Standing on this wall, Yu Ling saw the thickness of this wall, giving people a very strong sense of security.

And I can see clearly what is inside the wall.

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

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

Feather Spirit jumped off the wall, no matter what, the owner here would not have set up a mechanism inside the wall.

Besides, those plants grow so luxuriantly, without any signs of destruction, they should be fine.

She explored the fortress with confidence, and from time to time she took a few fruits to satisfy her hunger.

Soon she was in the center of the fortress.

There is a very strange structure standing here, not so much a house as a fortress with shrunken rows.

The walls are also full of holes for machine guns, and there are also things like turrets on them.

But these probably didn't start, otherwise, she wouldn't be standing here safely.

The door was unlocked, and Yu Ling cautiously walked inside.
