Armageddon: Shelters Can Be Upgraded Infinitely

Lu Yan flew to the foot of the mountain forest. After arriving at the camp, he first went to see the ice cellar made yesterday.

Opening the ice cellar door, a chill hit his face. Through the gaps in the iron frame, he saw the ice cubes he put in yesterday. After more than ten hours of melting, the volume of these ice cubes had shrunk by one-tenth.

At this melting rate, refilling the ice cubes once a week is enough.

Lu Yan was very satisfied with the performance of the ice cellar. He put some relatively perishable meat into the ice cellar. Starting from today, he will gradually transfer the food and sundries from the underground shelter here!

He already has a complete camp design drawing, and with the gold finger for point upgrade, he can perfectly reproduce the camp in the design drawing into reality in up to five days.

The first thing to build is a city wall... Lu Yan opened the design drawing. He was going to start building the camp today. As the home of the pig-headed people who have lived for generations, the geographical location of this camp is very advantageous, with it being located in the left, right and back directions. The huge mountain serves as a natural protection, and only a strong city wall needs to be built on the front to resist the invasion of most enemies.

When the pig-headed men were building the city wall, they used giant wooden piles. Although this material is convenient, its defensive power is not top-notch. Once it uses fire attacks, it will be easily defeated. And most importantly, the wooden city wall is difficult to withstand the mountains and forests. As can be seen from the invasion of those large dead creatures after the last Blue Moon Tide, if the Pig-headed Forest had not been attacked by dead creatures, it would not have been so easy for Lu Yan to capture it!

It seems that although the pig-headed tribe has metallurgical technology and the technology to refine gunpowder, they do not seem to know how to make lime...

Although Lu Yan also doesn't know how to make lime, he has a cheat!

With the help of the doomsday survival system, as long as you pay the same amount of points, you can complete gorgeous upgrades!

Just do it!

Lu Yan first cut down some wooden branches with an ax at the old location of the pig-headed camp wall and inserted them into the ground. He then braided the wooden branches together with wires to form an extremely crude fence.

After the completion, Lu Yan turned on the system and set his sights on the fence again.

Soon, a large amount of information appeared in front of him.

[A row of crumbling wooden fences]

[Defense: 1]

[Explanation: It seems that a gust of wind can blow it down,

Defenseless, even against a rabbit! 】

Seeing this comment, Lu Yan was not surprised at all. The fence itself was a crude product, and he did not expect it to be able to block any attacks. The next thing was the focus.

Below the comments, there are two upgrade directions.

[Upgrade Direction 1: Upgrade the fence to a stone wall to enhance defense! Survival points cost 800! 】

[Upgrade Direction 2: Upgrade the fence into a craft railing to enhance its aesthetics! Survival points cost 100! 】

Seeing these two upgrade prompts, Lu Yan had a smile on his face. He chose the upgrade direction without hesitation. Although a lot of survival points were consumed, as long as the stone walls were built, the safety of the entire camp would be improved. Improve it to the extreme, so that even if you don't return to the underground shelter at night, you don't have to worry about being attacked.

With a flash of light, the numbers in Lu Yan's points column dropped instantly. At the same time, the fence in front of him quickly twisted, rising and deforming, forming a city wall!
