For the next two days, the atmosphere in the villa was unusually dull.

As is customary, drones still go out on patrol every day, and they also fly over supermarkets. There are more and more words for help on the floor-to-ceiling glass windows on the second floor of the supermarket, and even some graffiti drawings of young children have begun to be pasted.

In the crooked picture, children are holding hands and playing, being hugged tightly by their parents, or running freely on the grass under the blue sky. Those bright colors and carefree scenes are extremely worrying.

With each passing second, they are one step closer to death.

“…… No matter what, we have to think of a way first, right? If it doesn't work, it's never too late to give up. Do nothing and just watch them die...... It's really painful. ”

The first one who couldn't hold back was Lu Rulan.

"Maybe we can really figure it out." Duan Whale looked at Su He, "Try to do something, at least you won't regret it later." ”

"What do you think?" Su He looked at Du Yunfei, "I listen to you." ”

Du Yunfei also looked at him: "You know what I will do." ”

After several days of struggle and struggle, the decision to "save lives" was finally unanimously approved. For a moment, everyone felt relieved, but the new pressure soon returned.

Everything at hand was put on hold, and everyone sat down to negotiate a plan of action.

Duan Whale first set the tone: "Our operation is to save people, and what we want to save is not only the lives of Teacher Hu and the three children, but also the safety of each of us." So I propose that Article 1 stipulate that once anyone is seriously injured in a rescue operation, the operation must be stopped unconditionally. Putting one's own human life above all else, agree? ”

"Agreed."

"Okay."

"Of course."

Everyone nodded. Lin Youqing, who was on the side, turned on the projector and hit the electronic map on the snow-white wall.

"The straight-line distance from Foguang Island to the supermarket is about 35 kilometers. Considering that the current surface roads are basically destroyed by the roots of the cypress, it takes about an hour to drive there. ”

"And that's not counting the time to deal with zombies."

Su He picked up a bamboo pole and gestured the road on the map: "According to the normal route, to get to that supermarket, we must first pass through the urban village, and then go northeast." Although the Dian cypress has been cleaned up, there are still a large number of zombies left in the village, and if it is tough, it will definitely be us who will suffer. ”

Haichen hypothetical: "Can we take a detour?" If we land by boat, then the nearest supermarket from the shore is only about three kilometers away. ”

"But for these three kilometers, we have to walk on our feet." Duan Whale rubbed his eyebrows: "Without a car, how can we successfully avoid all the zombies?" This issue must be addressed as a matter of priority. ”

Lin Youqing proposed: "Maybe we can make some modifications to the engineering vehicle, such as adding steel plates and iron barbed iron on the outside. Although it will increase the burden of fuel consumption, our diesel fuel should be sufficient. ”

"Maybe we can make some weapons, like □□ or something......"

Everyone has a lot of ideas, but when it comes to it, I feel that something is missing, and I can't make up my mind for a long time.

In this way, we discussed for more than two hours. The satellite phone on the side rang suddenly.

The call came from Qinghai. Such contacts outside of routine meetings often have only one purpose – early warning.

The fourth typhoon of the year is coming.

Unlike the three previous past typhoons, the new one will almost certainly make landfall in the coastal area of Z City. Even if it does not hit Foguang Island head-on, the winds and torrential rain that follow are by no means comparable to the previous typhoons, and even cause a violent storm surge that swallows up the coastline.

At the moment of natural disasters, there seems to be no other way than to carry it hard. Everyone said that they would seize the time to take precautions, and by the way, they told Zhu Yixin about the decision to rescue Hu Siyu and the three children.

“…… Did you really decide to do this? Zhu Yixin's voice also sounded a little excited, "Actually, I wanted to tell you a long time ago that there are experienced rescue teams in the two resettlement sites of Bauhinia and Mirage. Especially the mirage, I heard that their team once traveled more than ten kilometers and rescued more than a dozen people from the city center full of zombies. Maybe you can hear how they do it. ”

The stone of the mountain can be used to attack jade, which is indeed a good suggestion. After ending the call with Zhu Yixin, Duan Whale decisively got in touch with the mirage.

The leader of the mirage rescue team is a capable woman named Qin Zhen. She used to be the local coast guard, and when the apocalyptic disaster broke out, she went out on a mission; But the family and husband were unfortunately killed, and only the 11-year-old daughter was saved.

Perhaps it was precisely because of this that when he heard that they decided to take risks to rescue an adult and three children, Qin Zhen did not say a word of dissuasion, but instead taught his rescue experience.

And it was these words that gave the people on Foguang Island a great inspiration.

Neither by land nor by sea is the best choice. It's too impractical to build a hot air balloon or an airship or something. The real way to go is still under your feet – or rather, underground.

Every city has a huge stormwater drainage system. Under normal working conditions, the access openings (i.e., manhole covers) of the stormwater pipes are closed. Large drains are secluded and inaccessible. Even if a few entrances and exits are unexpectedly opened, there may not be zombies who happen to enter. At the very least, the chances of encountering zombies underground are much lower than on the ground.

"There's only one danger in getting underground."

Qin Zhen emphatically emphasized: "Dian cypress, those trees, its roots will reach into the cracks of the sewer. You have to be careful, you have to avoid those roots. Otherwise, zombies will be continuously led into the sewers by it, and it will be dangerous at that time. ”

“…… Maybe we don't have to face such a problem. ”

Su He, who was lying on the table and listening, suddenly raised his head: "The time and place are favorable, I think we should have found the best way to save people." ”

Suhe's reason is simple - a typhoon is coming. According to the forecast in Qinghai, this typhoon will trigger a strong storm surge. This means that tides and wind and waves can pour seawater into the seaside outlets. This high concentration of seawater can "corrod" the roots of the Dian Cypress that fall into the sewer pipes.

And the benefits of a typhoon don't stop there—the abundant rainfall washes away all sorts of debris in the sewers. From dead leaves to garbage to zombies, even if there are remnants, they are absolutely unrecognizable and not to be feared.

But that doesn't mean there are no problems at all – first of all, how to identify the sewer to the supermarket is one of the biggest technical tasks.

Fortunately, Captain Qin provided them with a lot of valuable experience.

Stormwater pipes are often laid along the surface road, but they extend various side branches to communicate with adjacent manhole covers and rainwater grates. In order to facilitate daily maintenance, each group of manhole covers in the same direction is marked with a serial number on its surface, and the same serial number can also be found at the bottom of the well below this manhole cover.

Therefore, as long as the number of the manhole covers along the road is written down, and the relative position and distance between each other are clearly marked, you can grope all the way to find the location of the supermarket.

Of course, all this is still just theory. To really determine if it's feasible, you need to go through the most critical step – on-site certification.

According to the frequency of setting up a manhole cover every 50 meters on urban roads, there will be 80 manhole covers to be recorded in a four-kilometer road section. That's a lot of work. Luckily for the unfortunate, they also have drones.

Without further ado, this tedious task was assigned to the youngest Haichen and Lu Rulan. Small drones deftly lift into the air and slowly cruise along the coastline according to an electronic map.

They really found it.

Just near the mouth of a small river, beneath the tall levee, hides a huge cement culvert. Although the cave is dark and you can't see the situation clearly, the word "rainwater" and a series of numbers are clearly written on the outer wall in red paint.

Lu Rulan, who was on the side, quickly marked the map. At the same time, Haichen had already manipulated the drone to rise into the air and began to look down.

"There's a manhole cover here!"

Haichen quickly discovered the first target, and he quickly zoomed in on the picture, and soon saw the word "rain" and the number on the manhole cover. Lu Rulan also recorded them all.

"Next."

The drone flew slowly in the direction of the supermarket, and the manhole covers along the way were found and recorded one by one. The two of them worked together and were very busy.

Seeing that everything was going well on their side, the four members of the senior group also began to think about further details of their actions.

"We can't put six eggs in the same basket. Three people were left on the boat, and the other three went to save people. In case something happens to the economy, at least there are reserves. ”

This is the suggestion of Duan Whale.

Su He was accustomed to his passive and calm mode of thinking, but he still couldn't help but complain: "Before things have started to be done, you are already singing and declining, Mr. Duan, can you still do it?" ”

Duan Whale opened his mouth to argue, but Lin Youqing actually stood on Su He's side.

"Rather than preparing for the aftermath, it's time to focus on finding a safe way to the supermarket. We can't wishfully assume that there are no zombies underground, and the preparations that should be made should be done. ”

"How about some defenses?" Du Yunfei has always spoken and only said the main point: "Zombies can only attack us at close range." As long as we can keep a safe distance and then use weapons such as long poles to kill zombies, our chances will be great. ”

That's a good idea.

The sewer space is narrow, and there will be no extreme situation where hundreds or thousands of zombies will rush up and squash people. So as long as you make a "metal cage" and protect your own people inside, you don't have to worry about getting hurt even if you encounter zombies.

As for this metal cage, first of all, it needs to be light and easy to move, and secondly, it should not be too large to facilitate passage through narrow places in the sewer, and of course, it must be equipped with weapons.

Naturally, the designed work was left to Duan Whale and Lin Youqing, while Su He and Du Yunfei began to carry out materials and follow-up preparations for the rescue operation.

A day later, when Haichen and Lu Rulan successfully mapped all the manhole covers along the way, and passed the rescue decision to the people trapped in the supermarket through drones.

This was also the first time they saw the thin but strong girl in the supermarket, crying tears of joy. 166 Reading Network
