Global Catastrophe: Open with 1000 Acres of Survival Base

In the afternoon, Su Yuan asked Erhuang to continue planting food.

Instant noodles wait for the grain to mature and then start harvesting.

Su Yuan knew that after the meteorite rain, the demand for food would rise again, and various survival bases would try their best to reserve food.

Food is the hard currency of this era, so there is no need to worry about not being able to sell it.

Su Yuan wore an automatic auxiliary mecha and looked at the entire survival base on the ground.

The 1,200-acre survival base is in a circle.

The smart survival cabin is 50 meters away from the wall of the fully automatic titanium alloy armor.

The ground floor is like an inverted bowl, buckled on the ground, 5 meters high.

Behind the survival cabin on the ground floor are the land of speed and land of endurance.

On the right side, 10 acres of vegetable land have been specially cultivated.

Dabai would tell Erhuang what vegetables he needed and let Erhuang plant them.

Su Yuan had prepared various vegetable seeds in advance and placed them in the automatic warehouse.

Su Yuan planned while looking at the land.

Of the 1,200 acres of land, he still only plans to cultivate 1,000 acres, and then cultivate an additional 10 acres of vegetable land and 10 acres of high-quality grain land specifically for his use.

The warehouse occupies a small part of the remaining land, and the rest is unused.

Su Yuan first prepared to purchase giant water storage equipment.

Recycle the original 20,000 liter water storage tank.

The new giant water storage tank, which surrounds the wall of the fully automatic titanium alloy armor, should store at least enough drinking water for him for a year.

Su Yuan opened the system to search for water storage equipment.

Ordinary water storage equipment has 20,000 survival points.

200,000 survival points for large ordinary water storage equipment.

Giant ordinary water storage equipment 2 million survival points.

Semi-automatic small water storage equipment...

Su Yuan directly spent 2 billion survival points to purchase fully automatic large-scale water storage equipment.

[Fully automatic large-scale water storage equipment: It can store up to 1 million liters and has a constant temperature automatic sterilization and filtration function to ensure the quality of the stored drinking water. 】

Su Yuan estimated that he consumes about 100,000 liters of water a year, which is 100 tons of water.

If the water storage equipment is filled up, it will be enough for him to use for 10 years.

To store so much water, he would have to find a river or dig a few more motorized wells.

After the nuclear explosion, there is no clean water source in the world.

If you want to drink clean water, you must go through the evolution of water purification equipment.

Su Yuan still has 20,000 liters of water in his hand, which is enough for him to use for a while. He plans to wait for the meteorite rain to pass and look for a place to replenish the water source.

Then Su Yuan looked at the automatic dome again.

The automatic dome cannot be left without fluorescent lamps.

Now that the fully automatic titanium alloy armor above is turned off, all crops will not be able to grow if the fluorescent lights are not turned on.

Su Yuan plans to install an automatic solar power dome as one of the backup power sources for the production base.

A survival base cannot only have one power generation equipment. If the nuclear generator is damaged, it will be very dangerous without backup power supply.

The automatic solar power dome is to install solar power panels on the original automatic dome.

Su Yuan opened the system and searched for the automatic power generation panel.

Ordinary solar power panels cost 1 piece for 1,000 survival points.

Multifunctional solar power generation panel, 1 piece for 10,000 survival points.

Adjustable solar power generation panel, 1 piece of 100,000 survival points.

Automatically adjust solar power generation panel, 300,000 survival points per piece.

…

Su Yuan calculated that the size of a solar panel is about 10 square meters, and one acre of land requires about 67 yuan. 1,200 acres of land requires more than 80,000 solar power panels.

And he can't just use ordinary solar power panels, he also needs adjustable solar power panels that let in some of the sunlight to promote plant growth.

Su Yuan directly spent more than 24 billion to purchase more than 80,000 automatically adjustable solar power panels and installed them on the automatic dome.

An automatically adjustable solar power panel can generate 10 kilowatt hours of electricity per hour under sufficient sunlight.

Such an automatic solar power dome can generate approximately 800,000 kWh of electricity in one hour.

Su Yuan could not figure out how to use the two automatic wind energy generators, so they were temporarily placed on the automatic solar power dome.

The machine gun that was originally located on the steel city wall is now located on the 6-meter-thick wall of the automatic titanium alloy armor. It is easily damaged by meteorites outside the survival base.

Because the petal-like titanium alloy plate protrudes from the inside and does not cover the machine gun.

And the thickness is only 3 meters, which is the weakest part of the survival base.

Su Yuan planned to install a laser cannon on the vertical keel above the survival base to increase the attack power.

As for the machine gun outside, Su Yuan had no intention of recycling it.

Automatic machine guns are still very useful against ordinary alien beasts.

Finally, Su Yuan began to upgrade the land.

First upgrading his 20 acres of exclusive land.

Ordinary land: Level 0, yields 500 kilograms of ordinary grain per acre. For each level, the yield increases by 100 kilograms of ordinary grain.

Previously, Su Yuan spent 10,000 survival points to upgrade a thousand acres of land from level 0 to level 1.

In other words, it takes 10 survival points to upgrade one acre of land.

To upgrade to level 2, you need 100 survival points per acre.

Level 3 requires 1,000 survival points per acre.

Level 4 requires 10,000 survival points per acre.

In this way, every time ordinary land is upgraded to a level, all required survival points are expanded by 10 times.

Su Yuan spent nearly 2.3 billion survival points to upgrade 20 acres of land to level 9 of ordinary land.

Ding, the upgrade was successful.

[Ordinary land: level 9, producing 1,400 kilograms of ordinary grain per acre]

[Upgrading to high-quality land requires 1 billion survival points per mu. Each mu can produce 1,500 kilograms of ordinary grain and 500 kilograms of high-quality grain. 】

Su Yuan did not expect that upgrading high-quality land would be so expensive. He still had 10.25 billion survival points left in his hand, which was only enough to upgrade 10 acres of land.

If you want to upgrade 1,000 acres of land to high-quality land, wouldn't it cost 1 trillion survival points?

Su Yuan rubbed his head and said:

"Ni Ma, is there any way to save the cost of upgrading the land?"

"Master, yes! Master can use the laboratory to develop and improve the soil himself to achieve the purpose of upgrading the land!" Xiaoyu reminded.

Su Yuan suddenly realized that he had forgotten to build a laboratory.

So, Su Yuan spent 100 million survival points to build a laboratory.

The laboratory is built next to the warehouse in a hexagonal building with a height of 6 meters.

[Laboratory: Level 1, 600 square meters, equipped with a fully automatic research and development machine, which can develop multi-functional general technology projects. The first research and development is free, and each subsequent research and development requires 100 million survival points. 】

[Upgrade to level 2, 5 billion survival points. 】

"Master, you need at least a level 2 laboratory to develop the soil needed for high-quality land!"

"upgrade!"

Ding, the upgrade was successful.

[Laboratory: Level 2, 700 square meters, equipped with an intelligent research and development robot, which can develop fully automatic level common technology projects. The first research and development is free, and each subsequent research and development requires 1 billion survival points. 】

[Upgrade to level 3, 50 billion survival points. 】

Su Yuan did not upgrade anymore, and he only had 5.05 billion survival points left in his hand.

Su Yuan walked into the laboratory. It was a milky white building equipped with various experimental equipment and super computers for calculating and analyzing data.
