CHAPTER 148: CHAPTER 149: BUILDING DRAINAGE CHANNELS, ABSOLUTELY FOOLPROOF!

The world channel was buzzing with information at this point.

Survivors forced into their shelters by the sudden acid rain were now searching for ways to overcome the dual disaster of acid rain and floods.

The prematurely arrived acid rain had injured some of them, but it gave them a deeper understanding of this disaster.

If they couldn’t find a way to fight the disaster, this might result in the terrifying extinction of the remaining survivors!

"It’s now known that the acid rain causes more harm to the body than the previous snow, yet it doesn’t damage metals, rocks, wood, or dry grass... This acid rain seems completely different from the acid rain we know?"

"Indeed, the acid rain on Earth, no matter how severe, couldn’t burn holes in the body. Someone in our team ran outside saying he wanted to imitate Shawshank, and when we brought his body back, his face and hands were nothing but deep corroded pits."

"It seems as long as we prevent our bodies from touching the acid rain floods, we’ll be fine?"

"But if the flood invades the shelter, you’ll have no choice but to come into contact with it. But if it’s a flood, it can’t be too outrageous. I feel if it rises to two or three meters, we might as well all be done for."

"Speaking of which, would building a two-story house solve the problem? Think about it; if the system wanted to drive us to extinction, the first disaster would have sufficed."

"Yes, looking at these disasters now, although they are disasters, they’re not outrageous. For instance, the previous earthquake could have been a magnitude 9 or 10 to finish us off, but it was only an 8."

"It seems the idea of a two-story building is feasible. If that doesn’t work, the system wants us extinct. I now announce that those with a shelter design map can go ahead."

"What if you don’t have one?"

"Are you kidding? You can’t gather 400 survival points? There’s one in the Survival Points Mall."

The number of people speaking in the world channel suddenly decreased, and at the same time, the shelter design map became the best-selling item in the Survival Points Mall.

Meanwhile, Lin Yue, after reading the group’s chat content, merely shook his head in silence.

Building a second story is just a temporary fix.

Without a complete drainage infrastructure, a two-story building will still get flooded.

He spent 2000 survival points to purchase a "Drainage Design Map"!

A drainage system, as the name suggests, is a facility to quickly discharge accumulated water. In this world, it was initially unnecessary since there was basically no water to drain.

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

"Who would have thought the Survival Points Mall would sell this stuff?"

Lin Yue had no idea how to make a drainage system and lacked much of a concept of how it should be done.

He had only seen some in city streets.

Previously, while building stone walls, he really thought about making a drainage trench, but how to do it was difficult to figure out.

Now seeing it for sale, he was naturally delighted.

Lin Yue immediately used it.

If not now, it would really be a blind panic then.

[Drainage Channel: Stone/Iron Block/Copper Ingot/Cement/Plastic/Alloy X20]

Goodness, just like making a raincoat before, all kinds of materials can be used to create it, provided the quantity is sufficient.

Lin Yue looked over his various material reserves.

Cement was naturally absent, and plastic had other significant uses. Copper ingots were needed for wiring, and how could alloy be used for this? What was left was only rocks and iron blocks.

Although he still had some reserves of rocks, he had no idea how long and large this drainage channel could be made; his less than a hundred rocks might not be enough.

"Seems like I can only use iron blocks." Lin Yue, seeing his iron block reserve of 366 pieces, was also surprised that he had so many.

Lin Yue once again headed outside, spent 20 iron blocks, and chose to construct!

[Please decide on the location to establish the drainage channel]

Establish location?

Lin Yue thought for a bit; the outer side of the stone wall outside the shelter seemed the most suitable. The rainwater falling from above could conveniently flow away through the drainage channel.

So, the drainage channel would be built half a meter away along the perimeter of the previously constructed stone wall.

Lin Yue quickly chose the location, and with a green marker, the system indicated that it could be built.

In the next second, a one-meter-wide, one-meter-deep, and about five-meter-long iron drainage channel appeared at his designated location under a faint light!

"Not bad, it looks quite sturdy!" Lin Yue jumped into it, excitedly staring at the inverted trapezoid-shaped drainage channel.

Strangely, even though he didn’t dig it himself, it was hard not to feel this way when looking at the neat drainage channel.

"One definitely isn’t enough, continue, continue."

The rain grew somewhat heavier, the weather darkened, and the rain droplets clattered against the iron drainage channel surface, making a crisp sound.

Lin Yue continued creating drainage channels. He didn’t want to see accumulated water outside when he woke up the next morning and then have to deal with it himself.

Soon, with the extensive disappearance of iron blocks in the Storage Space, he finished setting up the drainage channels around the greenhouse and the shelter’s outer walls.

"Next, I have to lead the drainage channel outside; the workload is still significant."

Lin Yue wanted to rest for a while; from when he started working on the stone wall until now, he’d been nonstop. But this acid rain didn’t wait for him and seemed to be growing bigger, with even a few centimeters thick layer of acid rain accumulating in the drainage channel already.

The work needed to continue, and it’s not a small task.

Calculating the shortest route for the drainage channel to the door, Lin Yue proceeded with caution.

The ground was extremely slippery; if he accidentally fell, Lin Yue felt he might not be able to get back up.

The drainage channel extended forward, quickly emerging from the first stone door and then led out along the second layer alloy door from the outer side of the second layer wall.

Surveying his surroundings, Lin Yue noted a spot not far from the small woods already had a slight water accumulation. Further past that area, he’d seen a "river" and "lake" before.

Before the acid rain, both the river and lake water had been unbelievably foul, with significantly reduced water levels. He’d even disliked them at that time, but now, they seemed like good drainage directions.

However, Lin Yue wasn’t so foolish as to run the drainage trench all the way to the lake. Instead, he made use of the terrain, directing the drainage channel first to the water accumulation area and then directing more downward from there using drainage channels.

After doing all this, it turned completely dark, and Lin Yue hurried back to the shelter.

Fully opening the alloy and stone doors outward, Lin Yue kept an eye on the drainage channel beneath his feet, treading on the slippery mud, and finally returned to the only place in the shelter still open.

There, Bai and many Little Ice Lizards were waiting for him.

Taking one last look at the gloomy sky outside and the over ten centimeters of acid rain in the drainage channel, Lin Yue finally slipped back inside, sealing the entrance with the last stone wall.

The rain was gradually starting to intensify.

Lin Yue had fully completed building this flood-resistant fortress.

The disaster would arrive in less than thirty hours.

Lin Yue wondered if he could withstand this disaster this time!
