Speaking of the battle between humans and the zombie army under the command of the corpse control after the appearance of the corpse control, Chen Ran's thoughts couldn't help but fly back to the terrible 18 years in the past!

At that time, almost every day and every night, they had to be on the lookout for the invasion of those terrible creatures.

Even in the relative safety of the settlement, they did not get a good night's sleep.

Because of their settlement, the scale of which is simply not comparable to those large settlements.

There wasn't even a decent moat.

At this time, Wei Chen and the others couldn't help but feel shocked after listening to Chen Ran's description.

The pictures that Chen Ran had just described had already formed a very terrifying picture in their minds. The more I think about it, the more I feel that that is indeed the real trouble for mankind in the future.

And what they are doing now is just fighting some scattered zombies.

So Wei Chen couldn't help asking, "What...... Captain, if that's the case, even if we establish a settlement in the Northeast in the future, won't it still be dangerous? How can you keep those flying corpses at bay? Do we have to keep the settlements low to be safe? Among the fortified zombies, there will always be those who are good at digging tunnels, right? ”

In this regard, Chen Ran couldn't help but smile and replied: "Building a settlement underground is not a good choice. Because we human beings, if we don't get sunlight for a long time, our physical fitness will gradually become worse and worse. When the time comes, how will we fight the zombies! What to take to defend our homeland! ”

"As for the fortified zombies, it's true that none of them are particularly good at digging tunnels. But that doesn't mean they won't dig tunnels. ”

Chen Ran continued: "In fact, zombies are tireless creatures. They actually have certain advantages in digging tunnels. Also, don't forget that in addition to the enhanced zombies, there are also zombie creatures in this world. Some of them are also good at digging tunnels. ”

"So ......," Chen Ran finally said, "Building the settlement underground can't completely resist the invasion of zombies. Instead, it traps ourselves. Unless we can build the kind of reinforced concrete underground settlements with outer walls more than 2 meters thick. ”

Chen Ran also gave an example: "Just like now, Meng Yao and their underground military base. But in short, it's not a long-term solution. ”

"What should I do then?"

At this time, Wei Chen couldn't help but continue to ask anxiously: "If we can't build the settlement under the ground, then if we build it on the ground, won't it be impossible to prevent the zombies digging from the underground tunnels, let alone the flying corpses from the sky!" ”

At this time, Chen Ran said: "That's why we have to find a way to go to the northeast!" ”

He continued: "Winters in the Northeast are cold, so in the winter, the ground there is frozen and hard like rock, and you can't dig at all. Summers are wetter. In addition, we are going to build the settlement in the middle of the river island of the Nenshan River, and the soil is even more moist because it is surrounded by water. ”

"It's not easy to dig tunnels in this kind of place. The tunnel is easy to get into the water, and it is easy to collapse! With the wisdom of zombies, it is more difficult to solve these problems. Even if there are mutant zombies of the earth and water types, it is the same. ”

"Because under our watch, they have to dig tunnels, and it's not just a matter of digging a kilometer or two. They're definitely going to dig out of sight. Otherwise, if we just let a few shells pass by, we will definitely blow up their tunnels. And if the digging distance is too long, not to mention that the soil mutant zombies will not have time to reinforce the dampness of all places, and the water mutant zombies will not be able to pump water in such a long tunnel. ”

Chen Ran then said: "So over there, we basically don't have to worry about zombies digging tunnels from underground!" ”

"Whew!" After hearing Chen Ran's words, Wei Chen and the others couldn't help but feel a little relieved.

Because compared to the zombies from the sky, in fact, the zombies dug from the underground are more difficult to prevent.

At this time, Chen Ran continued: "As for how to prevent flying corpses from attacking from the sky. Actually, we don't have to worry too much. After the settlement is built, we can send more sentry posts on the surrounding walls to observe. The attack power of the flying corpse is not very strong, and if it can be detected in time, it is generally not too difficult to deal with. ”

Chen Ran finally said: "As for the night, we can find a way to find some night vision equipment." It would be better if there was an air defense radar! ”

At this time, Wei Chen couldn't help but feel relieved, and said with a sigh of relief: "Then what we're going to do next, is we going to find night vision equipment and air defense radar?" ”

Chen Ran nodded and said, "Yes!" It's important to us. Let's see if you can find it in some of the barracks. ”

At this time, Zhang Xiangdong couldn't help but ask a little nervously: "What if you can't find it, or can't find these devices in the short term?" ”

After all, these things, where there will be uncertain.

Chen Ran smiled and said, "I can't find it, there are other ways too." ”

He then goes on to give an example: "For example, we can use infrared sensors to place an alarm net in the air. Or to make it easier, you can also use a rope to make a spider web above the base, and then tie a bell to make an alarm. ”

At this time, Zhang Xiangdong couldn't help but say: "When the wind blows, won't the bell ring the same!" ”

Chen Ran said: "Stupid, you won't hang a rope down the net and tie a bell in a place where there is no wind!" The wind can blow the bell, but the string tied at the two ends is not so easy to blow. ”

"And ......" Chen Ran couldn't help but smile at this time and said, "Don't we still have a supernatural here!" ”

He then looked at Wei Chen and Zhang Xiangdong, and then continued: "One of you is a mysterious powerhouse, and the other is a water system. Both the golden pupil and the water mist can sense invading enemies. It's a living radar! With you here, what else is there to be afraid of! ”

At this time, the muscles on Zhang Xiangdong's face couldn't help twitching.

He knew that Chen Ran was going to treat him as a coolie again.

He couldn't help but squint his eyes suddenly, then looked at Chen Ran and said, "In this way, isn't your ice mist also able to sense the enemy's invasion!" Why only talk about me and not yourself! You want me to work again, don't you be lazy! ”
