On the World Channel, information is constantly passing through at this time.

The survivors who were forced into the shelter by the sudden acid rain are looking for a way to solve the double disaster of acid rain + flood.

The premature arrival of acid rain has hurt some of them, but it has also given them a deeper understanding of the disaster.

If we can't find a way to fight against the disaster, then maybe this disaster will cause a terrible end to the rest of the survivors!

"Acid rain is now known to be more harmful to the body than the last snow, but it can't do much harm to metal, rocks, or even wood or hay...... This acid rain seems to be completely different from the acid rain we know? ”

"Indeed, no matter how bad the acid rain on Earth is, you can't burn a hole in your body, and there was a fool in our team who ran out and said that he was going to imitate Shawshank, and when we pulled his body back, there was nothing good on his face and hands, it was all corroded pits."

"It seems that as long as we keep our bodies from acid rain and floods, we will be fine?"

"But if the flood is going to flood into the shelter, you have to touch it if you don't touch it. However, if it is a flood, it must not be particularly outrageous, and I think that if it rises to two or three meters, everyone will be destroyed together. ”

"Speaking of which, can it be solved by building a two-story building? You think, if the system really wants to bring us to a desperate situation, the first disaster will be fine, right? ”

"Yes, now look at these disasters, although they are all disasters, they are not outrageous, such as the last earthquake, just come to a magnitude 9 or 10, isn't it over, and the result is only 8."

"It seems that the idea of a two-story building is feasible, if this doesn't work, then the system wants us to be extinct, and now I announce that there are plans for the shelter that can be rushed."

"What if you don't?"

"Funny? Can't you get 400 survival points?,There's a survival point mall.。 ”

On the World Channel, there were fewer people talking to the world, and at the same time, in the Survival Point Mall, the shelter blueprint became the best-selling thing.

At this time, Lin Yue, after reading the group's chat, just shook his head silently.

Building a second floor is just a palliative but not a cure.

Without a complete drainage structure, the second floor should or will be flooded.

And he spent 2,000 survival points to buy a "drainage canal blueprint"!

Drains, as the name suggests, are facilities that drain stagnant water quickly, which is not needed in this world, after all, there is basically no water to drain.

But in the face of the impending disaster of acid rain floods, this thing is extremely useful.

"Who would have thought that this thing would be sold in the Survival Point Mall?"

Lin Yue doesn't know how to do drainage canals at all, and he doesn't have much idea how it should be done.

He'd seen some of them on the city's roads.

When he was building a stone wall before, he did have some ideas for making a drainage ditch, but how to operate it was really hard to think of.

Now that he sees that there are sales, he is naturally overjoyed.

Lin Yue immediately used it.

Not at this time, you will really be blind when the time comes.

[Drainage channel: stone/iron/copper ingot/cement/plastic/alloy X20]

Good guys, it's the same as the last time you made a raincoat, you can make it with any kind of material, if you have enough of it.

Lin Yue looked at his various material reserves.

Cement is naturally not available, plastic is still of great use elsewhere, copper ingots are to make wires, how can alloys be used on this? All that's left is stone and iron.

However, although there are still some reserves of stone, he doesn't know how long and big this drainage canal can make, and he is afraid that the less than a hundred pieces of stone will not be enough.

"It seems that the only thing to do is to use iron." Lin Yue looked at the iron blocks with a reserve of 366 pieces, and couldn't help but be surprised that he actually had so many.

Lin Yue came to the outside again and spent 20 iron blocks to choose to make!

【Please decide where to build the drainage canal】

Where to set up?

Lin Yue thought about it, and it seemed that the outside of this stone wall outside the shelter was the most suitable, and the rainwater that fell from it fell down, just enough to flow away from the drainage canal.

In that case, the drainage canal was built along the perimeter of the stone wall that had been built before for about half a meter.

Lin Yue quickly chose the location, and the system also used a green icon to tell him that he could build.

And in the next second, an iron drainage canal one meter wide, one meter deep, and about five meters long also appeared at the location he designated after a glimmer of light!

"Yes, it looks sturdy!" Lin Yue jumped into it, looking at the trapezoidal drainage canal that was upside down as a whole, and couldn't help but get excited.

Strange to say, although he didn't dig it himself, looking at the neat drain, it was hard for him not to do so.

"One is definitely not enough, keep going."

The rain was a little heavier, and the sky was getting darker, and the raindrops hit the iron drain with a crisp sound.

Lin Yue continued to make the drain, he didn't want to wake up tomorrow morning when there was already standing water outside, and he had to work hard to get this.

Soon, as the iron in the storage space disappeared in large numbers, he also laid the drainage canals around the outer walls of the shed and the shelter.

"Next, we have to lead the drain outside, and it's still a lot of work."

Lin Yue really wanted to take a break, he had been doing things since he started to make stone walls, but this acid rain didn't wait for him, it seemed to have a tendency to get bigger and bigger, and even in the drainage canals, a layer of acid rain a few centimeters high had accumulated.

The work needs to continue, and the volume is not small.

Lin Yue walked cautiously while calculating the shortest route from the drainage canal to the door.

The ground was already quite slippery, and if he fell, Lin Yue felt that he would be planted here and not run.

The drain continued to stretch forward, and soon the first stone door was exited under his manipulation, and then led out of the second outer wall along the alloy door of the second floor.

Lin Yue looked around and found that not too far from the grove, there was already a place where some water had accumulated slightly, and if he went further in that direction, it was the "river" and "lake" that he had seen before.

Originally, before the acid rain, the river and lake were stinking terribly, and the water level had dropped quite a lot, and he was still a little disgusted, but now it seems that it is a good drainage direction.

However, Lin Yue was not so stupid as to make a drainage ditch all the way to the lake from this direction, but took advantage of the terrain to first build the drainage canal to the location of the stagnant water, and then used the drainage canal to drain down from the location of the stagnant water.

After doing this, it was completely dark, and Lin Yue immediately returned to the shelter.

Opening both the alloy door and the stone door completely outward, Lin Yue paid attention to the drainage channel under his feet, stepped on the slippery mud, and finally returned to the only place where the shelter was still open.

And there, Xiaobai and many Xiaoice lizards were waiting for him.

Lin Yue took one last look at the gloomy sky outside, and there was already acid rain more than ten centimeters high in the drainage canal, he finally got into the door and blocked it with the last stone wall.

The rain gradually became heavier.

And Lin Yue has completely built this flood fortress built by him.

Next, there are less than thirty hours left before the real catastrophe comes.

Lin Yue wanted to know if he could carry this disaster this time this time!
