My Doomsday Shelter Unlimited Upgrades

The road was full of dust and rubble, dead bones and corpses, under the direct sunlight, not a single drop of water was seen, and the water pipes had already dried up for some time, and they were all covered with dust.

As for the liquid, there are quite a few. In the shadow of the ruins, there are many places where some liquid has accumulated, but the liquid is all rainbow-colored.

Red, yellow, blue, green, all kinds of colors are available, but there is no colorless one.

After just one glance, Chen Yang gave up the idea of ​​drinking directly.

How to drink colorful water?

Until he dies, he will never try a bite!

Chen Yang took out the bottle of water stored in the system, took a sip and quickly put it back.

Chen Yang has seen some scientific proofs before that people should drink at least 1000ml of water a day, but looking at the current weather, even 2000ml a day is not enough to quench their thirst.

The plan for obtaining water resources must be advanced again.

Chen Yang was helpless,

"Going forward, you will be a university."

Thinking of this, Chen Yang sighed helplessly. If it wasn't for this accident, maybe he was playing golf in college. He even chose golf for fun this semester.

"Wait...golf?!"

Chen Yang suddenly had an epiphany, his university is one of the few in the country that has a golf course.

The golf course has a vast space, and there are still some teaching buildings outside the golf course. I think they are almost collapsed now, but the collapsed ruins just serve as a good bunker for the golf course.

Isn't this just right for a shelter?

Without further ado, Chen Yang set off quickly. With a goal, his pace was much faster than before.

Finding the stadium in the university based on his memory, Chen Yang found that the situation was better than he thought.

The golf course is overgrown with withered grass, and it also shows a barren and water-deficient appearance, but overall it has not suffered much damage.

The most important thing is that the entrance of the stadium is not blocked by broken bricks and tiles, coupled with the closed loop surrounded by collapsed teaching buildings, if outsiders come to look for it, they must find this entrance to enter the stadium.

The decision is yours!

Chen Yang was overjoyed. The golf course is more than ten hectares. Even if the shelter is built bigger and bigger in the future, the space is still enough.

Another point is that there are many shopping malls around the university. If you settle here, you may be able to collect some resources in the surrounding area in the future.

Taking out the basic shelter, Chen Yang found a place in the center of the court and put it down.

Accompanied by a glare of light in front of his eyes, a wooden house with a relatively simple appearance rose from the ground.

【Basic shelter】

Owner: Chen Yang

Completeness: 100%

Space: 10m10m4m

Facilities: None

System comment: Dogs didn't live in the previous life, but now the host mainly lives.

Chen Yang ignored the system's black-bellied evaluation and carefully looked at the wooden house.

The wooden house is boxy and has no windows, only one door.

Moving his eyes to the wooden door, the system popped up a series of prompts again.

[wooden door]:

The door made of wood is very fragile and slightly anti-theft and anti-radiation.

Upgrade Direction 10: Reinforce the structure, increase the thickness, and improve the sturdiness property. [-] survival points are required.

Upgrade direction 30: Change the material of the wooden door, greatly increase the durability and various attributes, greatly improve the anti-theft ability, and need [-] survival points.

System Comments: Upgrading the door is not a loss!Fire prevention, anti-theft and anti-pharaoh!

Open the wooden door, enter the wooden house and see that the inside of the wooden house is empty, which really deserves the word "basic".

With a place to escape the heat, Chen Yang sat on the ground and studied the upgrade function of the system while resting.

In addition to consuming survival points, the upgrade function can also provide raw materials by yourself, and upgrade items by paying with survival points + raw materials, or paying with all raw materials.

For example, in the first way to upgrade the wooden door, after putting 5 units of wood in the backpack on it, the upgrade will no longer require survival points.

The second upgrade method is to upgrade the wooden door to a stone door. After he puts 8 units of stones and 10 units of wood on it, he still needs an extra 10 survival points, presumably because the materials are not enough.

In other words, survival points are actually universal materials.

In order to test the upgrade function, Chen Yang chose to upgrade the wooden door first.

Don't worry about the axe. According to his experience, this thing is a consumable item. Only when you are very rich will you choose to upgrade it. Otherwise, it is definitely more cost-effective to make a new one.

5 units of wood is not considered a rare item, and the loss can't be much.

With a thought, with a faint light, the wooden door has been upgraded again.

From the appearance point of view, the external structure of the wooden door has obviously become more complicated, and the construction between the wooden strips also uses some geometry to increase the strength.

【Thick wooden door】:

Doors made of more wood have improved anti-theft and anti-radiation effects.

Upgrade Direction 25: Reinforce the structure, increase the thickness, and improve the sturdiness property. [-] survival points are required.

Upgrade direction 40: Change the material of the wooden door, greatly increase the durability and various attributes, greatly improve the anti-theft ability, and need [-] survival points.

System Comments: Thickened wooden doors, anti-pharaoh, more peace of mind!

Chen Yang touched the enhanced version of the wooden door, perhaps because 5 units of wood have been used, and the survival points required to upgrade direction [-] have been reduced by ten points.

He is very satisfied with both the practicability of the system functions and the attributes of the upgraded wooden door.

Upgrade in one second, what bike do you need?

For this wooden door, if there is no system, Chen Yang guesses that he will have to work on it for at least half a day.

Even if the rest is over, Chen Yang hastened to the next step.
