Zhang Su lightly tapped his finger on his own cheek, and after listening to Luo Xun finish a few difficult problems, he sneered: "What's so difficult?" How do we protect in the base, how do we protect here? ”

Everyone looked at him in confusion, and Wang Duonuo pointed out: "But...... "......The outside is not as good as the inside of the base, and if those metal covers are seen from a distance and captured by satellites, it will be a problem!"

Zhang Su rolled his eyes and mocked his man: "Your IQ has been chased by zombies? Just find some green, gray paint and paint those shelves, which look like ruins from a distance? Can people still suffocate urine? ”

Similarly, everyone who didn't come up with a solution at first was silent - it seems that their previous IQ may really be eaten by the little guy.

Luo Xun stood up, and his eyes also lit up with excitement: "Okay!" Then decide first! Let's go back and discuss the specific things, and get rid of the dead plants first! ”

The basement is full of plant and crop debris, which are very obstructive and unsightly, but fortunately it is not too troublesome to deal with, but there are too many weeds and it is too time-consuming to deal with. But now, when there is a wave of zombies migrating and mutant plants besieged, what else can make Luo Xun and them more anxious?

The amount of food brought out is sufficient (because Song Lingling is there, so they don't need to bring water at all when they go out), so as long as they ensure that the food is sufficient, as long as they wait for the zombie army to pass by and then leave, they can safely find a way to leave here and go back to the base to pack their things.

The small group of zombies that chased after Luo Xun and them in the zombie tide are now all dead, but I don't know if they are too lucky, the place they are in is exactly the only way for the zombie army to move. These zombies have no wisdom at all in the process of marching, even if the front is full of thorns, they will not use their brains and make a detour.

Of course, this may also have something to do with the fact that the zombies passing through their location are actually only a small part of the fringe of the zombie army.

Luo Xun and the others first spent two whole days working on the dry grass on the two basement floors, and from the third day, they from time to time while tidying up the things in each room, and from time to time they ran to the highest floor to observe the situation outside with binoculars.

"The zombies are not going in the direction of the base, it seems to be going to the southeast region." Luo Xun said, still using a telescope to carefully observe the movement of the zombie tide.

Yan Fei raised his hand to the team, raised his eyebrows and said, "Don't you think there are more foreigners in the zombies?" ”

"Foreigners?!" Luo Xun only paid attention to the direction of the zombies before, and didn't pay much attention to the specific appearance of these zombies - except for the body shape and appearance that evolved too strangely, most of the zombies were actually similar, and they became numb when they saw too much. Now after being reminded by Yan Feiyi, Luo Xun really noticed that there were still some sparse yellow hairs left on the heads of many zombies, coupled with the relatively tall body and faintly visible deep facial features......

"It's really a foreign zombie...... Luo Xun frowned at the telescope, "Where did they come from?" Cross-border? ”

"Quite possibly, who made them always tireless and only go in one direction? Nearly two years is enough time for them to come along. ”

Foreign zombies are nothing, because Luo Xun believes that there must be many domestic zombies in China who will hike abroad, and even if the zombies can swim, then they may also drift across the ocean to the other half of the world to see the Americas, or maybe go to Australia to see if there are kangaroo zombies.

The advance of the zombie army is not yet in sight, although they are worried that something will happen to their home in the base, and now everyone has to stay here in peace for the time being. As for how they will leave the place surrounded by mutated plants after the zombie tide has passed?

In fact, the method is very simple, Luo Xun and the others thought of this method from the inspiration of the building they are in now - digging tunnels.

Although they don't have earth-based abilities, they do have a little pleasure. Although they don't have professional equipment, wood, etc., to strengthen the holes, they are not there.

As long as the past few days have passed, and the sand slowly melts out according to the direction calculated by Luo Xun, Luo Xun and the others will be able to find their way out safely.

Although Xiao Baozi's ability is very likely to be able to control those mutated devil vines, he is a baby after all, who can expect a baby to understand everyone's words and take the initiative to control the mutated plants? Luo Xun: They can't even communicate with the little guy now, so that he can use his abilities in the right situation, let alone this little baby who doesn't understand anything?

Luo Xun and the others have not been idle in the past few days, in addition to cleaning the rooms in this building, they also checked all the rooms in this building surrounded by devil vines, and found a lot of tools, equipment, and farm tools.

If the things that Luo Xun collected and bought back before the end of the world were some family, small portable tools, then the things in this farmland were all large, professional and various utensils.

What oil presses, sausage machines, dough sheeters and other machines for producing and processing grains and foods, and agricultural vehicles used for harvesting, irrigation, and sowing.

Unfortunately, these vehicles were apparently intended to be used on the surrounding farmland, but now that the farmland is full of mutant plants, how are they going to drive to harvest them?

After their inspection and confirmation, they found that there were actually several solar panels on the roof of the third floor. It's just that these boards are only connected to emergency lights and solar water heaters, and they were covered by heavy snow before, so they didn't notice it in the first place. So in fact, although some electricity is stored here, there is not much power left, and now there is only a little bit left.

On the fifth day after entering this real building, Luo Xun and the others finally saw hope - the number of zombie waves passing by outside had plummeted! Apparently it's already in the end part!!

Everyone discussed it for a while, and they decided to start digging tunnels first!!

Digging tunnels is a technical job, really.

Luo Xun first roughly calculated the trend, angle, length, width, etc. of the tunnel, and then relied on Xiao Xinran's skilled digging technology, as well as Yan Fei's metal to seal the four walls of the tunnel anytime and anywhere, so as to avoid the situation of gravel falling, and to prevent anything from getting in from the dirt to attack everyone, such as what mutated plants, such as what soil zombies.

Luo Xun and his men were responsible for transferring the excavated sand and putting it in the small square - the sand was dug up from the ground two floors underground, clean and fertile, and they were going to leave the soil to dry and crush, and then use it as soil for planting in the future.

The tunnel was also dug for two days, until it reached the shade behind a nearby bungalow, and in the end, the metal they brought along the way was simply not enough, and Yan Fei had to dismantle some things that could not be used for the time being in the real yàn room, which was barely done.

After another day, after making sure that the zombie army outside had completely disappeared, everyone opened the last section of the tunnel, and after Yan Fei went out, he directly removed the metal from several nearby bungalows and built an absolutely solid gate for this tunnel.

The road has finally been built, and although there will certainly be other problems that need to be solved, planned, and perfected in the future, they have finally reached the first step!!

"Brother Luo, what should we do now?" Finally opened the passage, Li Tie and the others looked at Luo Xun very excitedly, looking forward to the follow-up action.

Luo Xun touched his chin and pondered: "Go back to the base or go and get the solar panels back first......" When they were chased by the zombie tide and fled that day, they had to throw the metal box containing the solar panels in place......

"Those metal boxes are very sturdy, unless some metal zombies deliberately destroy them, there shouldn't be any problems. Even in the past few days, people from the base have passed by there, and I am afraid that they will not be able to get rid of them for a while. Yan Fei saw that he was entangled and helped him analyze it.

Xu Mei also nodded and said, "Our food is almost finished, it's best to go home early to replenish food, especially the cream fruit is almost finished......"

They came out with a lot of food this time, but the adults may be able to endure it for a few days, but don't forget that they still have children here! The cream fruit brought out for the little bun is almost finished, and if you don't go back, I'm afraid the child will go hungry.

Luo Xun nodded and looked around at everyone: "Go back first, if there is nothing wrong in the base, let's come out in a few days." ”

Everyone nodded in unison, all indicating that they had no opinion.

The tunnel leading to the outside was built by Luo Xun and the others very spacious, and the elevator in the real yàn building could fit at least one split sled car at a time, and soon, they transported the car out, found a good direction and rushed back to the direction of the base.

Fortunately, the sled can barely drive on flat ground, although it will wear out the metal plate underneath, but since Yan Fei is there, this is not a big problem.

A few days ago, when the zombie tide passed by, almost all the snow in the vicinity was trampled and rotted, revealing the ground below, and those devil vines could no longer "transport" the snow from other places as a disguise, so Luo Xun and the others easily let go of those dangerous creatures and drove all the way back to the base along the main road.

This time, because they were already familiar with the road and the snow outside was melting widely, it took them less than two days to find the car they had hidden.

Rushing all the way back to the base, the group returned to their downstairs as quietly as possible in the deep night, despite the stars.

After going back to the hallway, opening the door, and checking the house, they breathed a long sigh of relief that the house was fine.

I didn't have time to say anything, and the group of people who were extremely sleepy hurried back to their respective rooms, cleaned up a little and fell asleep, as for other things to discuss and care about? Tomorrow will be tomorrow, how can they still have the strength now?
