In this world, no one has yet prescribed such things as "pens" and "paper".

At least, judging from the chat logs, the trading mall, and the survival point mall, it can still be basically confirmed.

Without a pen and paper, Lin Yue could only find a piece of ground, use tree branches as pens, and write and draw on the ground.

"The area around the shelter cannot be without defensive facilities, like the ancient kind of city walls, which can resist certain attacks......

Lin Yue drew a dot in the center of the ground to represent the shelter, and drew an unclosed circle around it.

"Then, when building the city wall, you must also ensure a certain land range, and the gate seems to be only a stone gate, but this can also prevent ordinary mutant creatures......"

The walls can't keep people out.

The most ordinary survivors can get a ladder to climb over the city wall.

Lin Yue looked at the city wall he could make now, which was only about three meters high, and it was not difficult for people with ladders.

"So, what about an extra layer of insurance?"

He drew little × inside and outside the circle.

These small X's, which are closely connected, represent traps.

At present, Lin Yue can create two kinds of traps, the first is the normal type, and the second is the improved type.

The difference is also a matter of how much damage it takes, and in appearance, it is almost no different from an ordinary wasteland.

If it weren't for that, he wouldn't have gained so many times.

The traps inside and outside the city walls, even if they are of the ordinary type, can cause some damage to the so-called "wandering survivors" who want to sneak attack, and even make them retreat.

After thinking about it, it seems that there is only so much that can be done at the moment.

Indeed, it is also possible to learn the practice of making broken glass on the wall, which increases the damage on the wall and makes it difficult for people to climb over.

He did have a piece of glass in his hand, but it was a thickened version of plexiglass, which he had just gotten back from the hotel.

It doesn't seem like a good idea to break something so good, and wouldn't it be nice to use it in a better place.

However, we can only wait for the next secret realm refresh, and this is too dangerous at the moment.

"The next step is to put ideas into action." Lin Yue stood up, stretched his arms, estimated the distance, and decided to take this refuge as the center, and the radius of fifty meters was the range of this city wall.

The 50-meter radius allows him to expand the shelter later, or place some things or buildings such as soilless cultivation and the simple plastic greenhouses obtained at that time, which are too large and consume more materials, and smaller ones will not be able to be placed, so this 50-meter radius seems to be the most suitable.

Tie the yarn to the chimney on the top of the shelter, and then stretch it as far as possible to fifty meters - this is still quite easy for Lin Yue, after all, he only needs to use the measurement method he has done before, and it can be done simply.

Even if it's not that accurate, it doesn't matter, it's probably a circle.

Holding a wool in one hand and an iron spear in the other, he drew on the ground, and soon a circle with a radius of about fifty meters was ready.

When he had done that, he walked over to the stones piled up next to the shelter and began to put them into the storage space piece by piece.

Then, it is a simple and tedious process of creating a "stone wall".

Six stones can make a stone wall about three meters wide and three meters high, and Lin Yue found that the city wall can also be made out of some arcs.

The wall is not thick, only thirty or forty centimeters, but it is quite sturdy.

According to the formula for calculating the circumference of a circle, the circumference L=2πr, and the circumference can be almost 314 meters.

Then you have to make about 110 city walls, and the stone cost is about 660 pieces.

Good guy, after doing this calculation, I found that the demand is really a lot.

Add in the traps that need to be crafted inside and outside the stone walls......

Wood and iron also consume a lot.

Looking at his material reserves, he really has a lot worse, especially the stones, which are only more than a hundred.

"There's a long way to go."

Lin Yue made dozens of walls out of the existing stones, placed them in the places he had planned before, and returned to the shelter.

Xiaobai is still sleeping, how can this little guy sleep so much.

He Xiaobai pushed it from the mat inside, and lay down on the comfortable bed with the word "pull".

After the snow disaster passed, although there was no heat caused by the fireplace, the temperature returned to about 30 degrees, which still made Lin Yue feel hot.

After opening the game panel that he hadn't opened for a long time, he briefly browsed the group as usual.

", you can call me Emperor Ou in the future, I just used the last 5 survival points to pump out 20L of water! Do you dare to think? ”

"Big guy cow pie!"

"You're not going to be a dog of the system, are you?"

"That is, I threw more than a hundred points into it, and there was no splash, okay?"

"Ask for a deal, you can't drink 20 liters of water, why don't you let me help you solve it!"

"Still need water? Didn't you notice that there are more bugs or something now, and even if the odds are low, you can still get some water? ”

"Queshi, after my parents came, the system brought 3 liters of water for each person, and these 6 liters of water are enough to last for a long time if you save a little drink."

"Pass it on, water profiteer Lin Yue cried and fainted in the shelter."

"Passed on, the black-hearted profiteer Lin Yue drank water with tears and died."

"What are you doing? When Lin Yue sold water to you to continue your life, Lin Yue shouted every day, Lin Yue Boss Lin Yue shouted, now there is a little water, that's it? ”

"That's it, although it's not much, but Lin Yue is not black, compared to the one that will sell 15 ml and 20 ml and require a bunch of wood and stone, it's just a lot more conscience."

"Haha, don't run any of these people, if I were Lin Yue, I would give you a blacklist!"

"Hey, there are still fans with the surname Lin? Do you think that the profiteer will look at you more? Laughing pee. ”

"Lin? Oh, Lao Tzu just burst hundreds of insects and eight wooden treasure chests, some of which are water, who will beg him? ”

……

Lin Yue silently peeked at the screen.

Originally, he saw someone talking about the lottery, and he looked at it with interest, but as a result, these people talked about him while chatting, and some people tried to bring rhythm and make his reputation stink further.

Fame is still important, at least when selling things.

However, he really didn't expect that now because more mutated creatures are placed in the system, even the kind of mutant bugs that ordinary people can kill, as long as they explode enough, the probability of obtaining treasure chests will also increase, and it will become much easier to get water.

But this is only temporary.

One more person, one more mouth.

Drinking water and eating, how can one person make do with himself, two people, especially if there are people around who are unable to move and can't help survive?

After a long time, there will still be a shortage of water, after all, the demand has become larger, and it will be more uncomfortable when you are used to drinking water in large gulps and get stuck because of fewer resources.

Maybe only one like him is living alone, and life really doesn't have to worry about anything for the time being.

Looking at the upper right corner, the number of people in the group of 10,000 people has dropped again, and now the number is 9,811.

Lin Yue silently blocked a few more people and looked at the mall.

He is not a saint, and when someone slaps him, he will hand the other half over and let the family beat him.

If you get cheap and sell well, then you will be blacklisted in the future, and don't cry when you run out of water.

When you ask me, I will have to pay more for me when the time comes, and I will agree!

For example......

Right now?
