Global Cataclysm: Infinitely Upgrade Shelter

"Next, Grain Planters!".

“........."

The storage problem of fresh beef and fresh mutton has been solved.

Zhao Chen didn't stop his steps, and rushed to the 'grain planting room' non-stop, which is related to his future eating problem, and he definitely needs to pay attention to it!

As if tempted, I silently recited in my heart

"Additional property – drip irrigation system. "

“......."

[Ding, small grain growing room, additional 'drip irrigation system' attribute].

[Drip irrigation system (primary): it can save 70% of water consumption, save 50% of fertilizer consumption, and slightly increase grain production].

[Survival Point: 1000].

【......】

Just add a drip irrigation system.

It takes a full 1,000 survival points, and Zhao Chen, who watched it, felt heartache.

Although there are still 1040 survival points left in his hands, which has met the conditions for upgrading, he can't be so bad.

If you upgrade directly.

It's a waste of precious survival points.

"Inquire about the raw materials required for the upgrade. "

Drip irrigation system (primary).

[Upgrade raw materials: water pumps, power machines, fertilizer tanks, filters, control and measuring instruments, drippers, water pipes, ........].

A list of raw materials was presented in front of Zhao Chen.

Some of the materials are easy to get your hands on.

Some materials are very troublesome to get their hands on, at least not now.

"A drip irrigation system needs so many things. "

"Drippers and water pipes account for half of the entire drip irrigation system, and plastic materials can be manufactured with 3D printers. "

"For other materials, it can only be fate. "

"After all, 3D printers are so large that they can't print anything too big. "

"If you only print parts, you don't have decades of mechanics, and it's impossible to install them. "

“......."

Frowning, Zhao Chen thought silently in his heart.

In short, being able to reduce the consumption of survival points is a good thing, and you can't pursue it every time, 90% of the survival points are reduced.

As for how to get plastic materials.

Zhao Chen already had an idea.

The large amount of survival materials that I have stored may not be of high value now.

However, when the state announces the news of the global catastrophe three days later, it will definitely multiply dozens of times.

Even more than a month later, the global catastrophe has really come, and it is possible to directly multiply hundreds or thousands of times, and it is absolutely priceless!

When the time comes.

Just take a few cabbages that you can't eat, and maybe you can exchange them for the supplies you want.

Not really.

Just go to the plastic factory in the main city, there will always be a harvest.

"Wait a few more days. "

"Once we got the materials, we upgraded the drip system. "

"Additional attribute - soil quality improvement. "

[Ding, small grain planting room, additional 'soil quality improvement' effect].

[Soil quality improvement (primary): Raise the ordinary soil quality to the level of 'black soil', and the grain yield will be increased to a certain extent].

[Upgrade Raw Materials: 100 tons of high-quality dirt].

[Survival Point: 200].

【.......】

Compared to expensive 'drip irrigation systems'.

The survival point required for 'soil quality improvement' is to save a lot, and it is very simple to upgrade raw materials.

Of course, 100 tons of high-quality soil.

Zhao Chen can't get it for a while, so it's impossible to go all the way to the agricultural base and dig the soil directly, right?

Three days.

It really doesn't have to be able to support a round trip.

"200 survival points, which is still within the acceptable range. "

"Let's just upgrade. "

[Ding, small grain planting room, additional 'soil improvement' attribute, survival point -200].

[Remaining survival points: 840].

【........】

Accompanied by the deduction of survival points.

The

quality of the soil in the entire grain growing room has undergone earth-shaking changes.

The

soil becomes dark and shiny, the soil is delicate and fluffy, and when you pinch it lightly with your hands, you even have the feeling of pinching out the oil, even people who don't understand agriculture know that this kind of soil is very fertile.

That's it

The

most fertile black soil in the land of dragons!

It is a natural treasure given by nature to human beings, and its fertility is extremely high, which is very suitable for the cultivation of crops!

After all, black clay develops on a variety of mafic parent materials, including calcareous sedimentary rocks, mafic igneous rocks, basalts, volcanic ash, and sediments formed from these materials.

The nutrients and minerals contained in it are far from being comparable to ordinary soils.
