After collecting enough hedrons, Tianlan stopped staying here.

After all, now that the doomsday level has just been raised, there are still many uncertain factors, so you must be cautious.

Never stay outside after dark, that is when zombies are most active, and if you can go home as soon as possible, you can return home as soon as possible.

After returning home, he saw the house built by Yu Ling again, and he couldn't help but remind: "There are levels and angles, you can take them." ”

"Oh." Subconsciously as a result, the tool handed over by Tianlan, Yu Ling looked confused.

Am you being ridiculed?

I just wanted to ask clearly, but I couldn't see Tianlan anymore.

In desperation, Yu Ling had no choice but to give up, looking at the house he had built, and couldn't help asking, "Is it that bad?" ”

Specifically, of course, it is very bad, the wall is crooked, and it will collapse at any time.

From a distance, it looks like a building block built by a child, and it will collapse if you push it.

After glancing at his house again, Yu Ling took the tools left by Tianlan and returned to his tent.

I'm tired today, so don't think about it so much and rest early.

After Tianlan returned to her room, she also lay down in her bed and fell asleep.

I hadn't had a good rest in the past few weeks, and now that the energy gun was finally built and the hedron was ready, it was time to take a good rest.

During this break, Tianlan had a rare dream.

That was a time ago, when I hadn't gone to college and was still in high school there.

I still get along with my parents.

When he woke up from his dream, he felt a sense of emptiness.

Yes, there is nothing around me anymore, some are just barren, and my heart has long since died, and now all I have left behind is an empty shell.

Who knows.

Rising from her own specially made bed, Tianlan began today's work.

Get out all the energy guns you've made, it's time to replace those thermal weapons.

Although it was a replacement, Tianlan did not plan to completely replace the original firearms with energy guns, but added a circle on the wall to replace some firearms appropriately.

Just do it, Tianlan took all the things and walked out of her house early in the morning.

At this time, Yu Ling, who had just gotten up, lazily scratched his stomach, yawned, and walked out of his tent wearing only a pair of underwear.

As soon as she came out, she saw Tianlan.

It's weird, usually, shouldn't this guy show up again in a week, why did he come out so early this time?

Hawkers, it doesn't matter, anyway, it doesn't affect any work.

At this time, she didn't realize what she looked like, and she started her work according to her habits.

Usually she's the only one here, so she can't help but wear only one ** to work.

The unprecedented sense of openness made Yu Ling energetic, sleepy or something, and it disappeared in an instant.

When a piece of land was watered, the only remaining shame she had finally started to kick in.

"You...... You, you, ......! Why are you here?! Yu Ling hurriedly protected his body to prevent himself from being in front of Tianlan again.

Regarding Yu Ling's reaction, Tianlan sneered, and there was no reaction.

This ...... What does that mean?! Am I so unsightly?!

Yu Ling was angry, although she was not so confident in her figure, but it was also a normally developed body.

Seeing his own **, he just sneered, and looked down on people like that?!

"What do you mean? Make it clear to me! ”

Faced with Yu Ling's questioning, Tianlan didn't have any intention of answering, and walked towards the wall alone.

Replacing firearms like this, Tianlan didn't seem to leave it to Yu Ling to do.

The first is that he hasn't fully trusted Yu Ling, and the second is that even if he does, he doesn't think Yu Ling can do this.

Seeing Tianlan ignoring herself like this, Yu Ling was hit by a huge blow.

Case...... In that case, then the old lady will not wear clothes in the future, see how long you can last!

At this time, Yu Ling felt that her self-esteem as a woman had been greatly hit, and she began to seriously doubt whether she was a woman.

Tianlan didn't care what Yu Ling was thinking at all, and now he was concentrating on upgrading the defense of the wall.

Some of the firearms are replaced, and as for the infrared perception system, it can be connected directly.

When Tianlan made the energy gun, he had already made the link to the automatic, so when it came to replacing it, it didn't take much effort and it was completed quickly.

Wiping the sweat from his forehead, Tianlan finally breathed a sigh of relief at this time.

In this case, not to mention the third-level zombies, the second-level zombies will definitely not be able to get close to the fortress walls.

As for air defense, it doesn't take much effort, just adjust the perception range and set the gun to prioritize attacking the air.

There is a ten-meter-wide river on the ground, so you don't have to worry about zombies being able to cross it, the most important thing is in the air.

But now that I think about it, it's been a long time since I've seen the crocodiles I've fed, so let's stop by now.

After leveling up, Tianlan came to the top of the fence and looked at the crocodiles below.

Now these crocodiles have changed, after all, they have always grown up eating zombies, and it is a matter of course that they will change.

But they didn't become zombie dogs, they were still living animals.

But they are no longer ordinary animals, and their fangs are much sharper than those of ordinary crocodiles.

The body length has also changed greatly, twice as long as the normal one, and the personality has become extremely fierce and irritable, and will attack other members of the same kind if there is little discord

Tianlan suddenly remembered that these crocodiles had also been trained by herself, and she didn't know if she would listen to her own words now.

Tianlan, who was facing like this, whistled and gave orders to the crocodiles.

When the crocodiles heard the whistle, they instantly rioted, not only did not act according to Tianlan's intentions, but also attacked all the creatures around the crane.

But everything that can be touched, all of them are bitten apart.

In an instant, Tianlan fed half of the crocodiles.

Seeing such a result, Tianlan was not angry and disappointed, but laughed.

According to what I observed just now, these crocodiles have not only changed on the surface, but their strength has also been greatly improved, and they can tear apart any companion in one bite, which is very powerful.

With such a bite force, without protection, Tianlan was not sure if he could withstand it.

After the crocodile had eaten enough, it stopped rioting, and continued to bask in the sun leisurely, returning to the appearance that Tianlan had not come.

Although these crocodiles have become uncontrollable, they are also a very strong means of defense, which is very good.

It's just that these crocodiles still have production capacity, Tianlan became interested.

If such a vicious crocodile can reproduce itself, then this moat will be an insurmountable obstacle.

No zombie can cross it.

But then again, Tianlan remembers that she has not only crocodiles, but also fierce predatory catfish like the six-whiskered catfish.

I haven't seen one yet, and I don't know if there are any ones alive now? Haven't you been eaten by crocodiles?

Thinking of this, Tianlan returned to the inside of the fence and used the detection machine on the wall to observe the situation in the water.

Infrared perception has almost no effect in water, dynamic capture perception does not play any role, and the only thing that can come in handy is sonar perception.

In fact, Tianlan didn't tell Yu Ling clearly at first.

It's not just three sensing systems, it's all of them.

It's just that under normal circumstances, other systems will produce false positives, so Tianlan usually doesn't use these.

The three perception systems mentioned earlier are the most accurate.

Sonar circles sweep the situation in the water.

There was nothing resembling bones underneath the water, which was beyond Tianlan's expectations.

So far, there have been many zombie waves to besiege them, and it is not that no zombies have reached the water's edge.

The zombies also sank a lot of corpses, but none of them resembled bones, which was unexpected.

The sonar continued to scan the water, and then Tianlan noticed something.

There are small fish in the water, and the number is very large, several times more than crocodiles.

Tianlan didn't remember that there were other fish in the water, which meant that they were all seedlings of the six-whiskered catfish.

This discovery brought a great surprise to Tianlan.

Any fry is already too small with the arm, and I believe that soon these will be a new batch of powerful predatory beasts.

At this moment, a huge beast suddenly appeared in the detection screen, swallowing all the fry that appeared in front of him in one gulp.

This giant beast is about six meters long, very huge, and it is almost the width of this moat.

What a surprise discovery.

The crocodile has grown to about six meters, and now even the catfish are the same.

And the ferocity of the catfish is higher than that of the crocodile, the huge mouth that can devour the same volume, as long as it is bitten by it, it can no longer break free teeth, very terrifying.

It's not impossible to eat a zombie in one bite, and maybe even the crocodiles on the surface of the water are no match for these catfish.

Tianlan observed for a while.

These catfish were far more numerous than he had expected, because they would devour their own kind, and nothing they thought could escape their mouths.

Just such a creature brought Tianlan the expected surprise.

Their food is like a bottomless pit, the same kind, smaller crocodiles, zombies, all of them are their food.

It's many times more powerful than a crocodile.

It's also several times more fierce than a crocodile.

I didn't expect that there were such powerful guards outside my fortress, which was really reassuring.
