After seeing the introduction of the properties of the culture medium, Lu Yan laughed. He was very disappointed when he went on this journey to the mountains and forests!

It can independently meet all the conditions for crop survival, no need to fertilize, and automatically adjust the temperature. Although the water consumed every day is as high as 5l, the heavy rain yesterday made Luyan stock up a lot of rainwater. In addition to the daily cleaning consumption, it is completely enough to supply the consumption of culture medium!

"There are five 10l capacity wooden barrels that contain rainwater, which can fully support the culture medium for about a week. According to my observation of the wilderness environment, the rainfall cycle should be about 5-7 days! Otherwise, the soil below 30 cm on the surface will definitely not be able to remain moist at this high temperature for a long time." Lu Yan touched his chin and remembered the soil moisture content he found when he dug the drainage channel before, and quickly came to a conclusion.

The irrigation water source required for the culture medium is not a problem at all!

[Upgrade direction 1: Upgrade energy supply method, from electricity and water sources to solar energy supply! 300 survival points are required!]

[Upgrade direction 2: Upgrade crop quality, the product will be upgraded from (ordinary) to (high-quality) quality! 100 survival points are required!]

Two upgrade options appeared again in front of Lu Yan.

"The first thing is not to be considered. The electricity and water required for the culture medium are not under much pressure... and the survival point demand is also higher." Lu Yan turned his attention to the second choice naturally: "Improving the quality of vegetables? This is interesting!"

High-quality vegetables will not only have higher nutritional content and yield, but most importantly, their taste will also be greatly improved.

When I think of this, tears of incompetence flow out of my mouth.

"But the materials needed to upgrade the vegetable culture medium do not seem to be clearly pointed out..." Lu Yan scratched his head. He took out a large amount of steel, stone, wood and other materials from his backpack and placed them in front of the culture medium, but the survival point requirements in the upgrade option have never decreased.

Obviously, the materials required to upgrade this culture medium and other technological products are completely different from the materials used for upgrading the basic products of wooden walls and cold weapons, and even Lu Yan can't take them out for a while.

"Buy some seeds and fuel first, and use the generator and culture medium!"

Lu Yan rubbed his hands. The moment he saw the culture medium, the planting talent engraved in his bones was activated. Lu Yan didn't want to waste a second, and he had to use it as fast as possible!

There is only one requirement for the choice of vegetables grown in the culture medium...that is, the growth cycle must be short!

Five days after entering the wilderness, Lu Yan ate tasteless air-dried vegetable buns, and the birds were about to fade out of his mouth. He longed for the touch of tender, green vegetable leaves being cut by his teeth!

With a planting area of ​​25 square meters, road rocks are determined to be divided into five different areas.

The first part of the planting tomatoes is high in yield and is rich in moisture and sugar. It can not only be stir-fried for soup, but also eaten as fruit.

The remaining four parts are used to grow cabbage, leek, cherry radish and chicken feathers!

Among these five vegetables, except for the longer growth cycle of tomatoes, which is about 110 days, the other four vegetables can only be ripened and harvested in about 30 days, and are suitable for intensive cultivation and have a huge yield.

Soon, Lu Yan used the spear that stabbed the pighead to death to death to the trading yard to exchange 30l of fuel and more than a dozen packs of various vegetable seeds.

After sorting these seeds into the soil of the culture medium, Lu Yan walked to the front of the silent generator with a large bucket full of fuel.

Unscrew the lid of the filling port, and as the golden fuel oil poured into the generator fuel tank, this technological product slowly regained its vitality!

"TuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTuTu

After Lu Yan grabbed the starting cable and pulled it hard for a few times, as the irritating engine start sounded, a stream of blue smoke rolled out from the generator exhaust hole.

Generator, running normally!

A smile appeared on Lu Yan's face. The small stream of blue smoke coming out of the generator had a pungent smell, but he did not feel disgusted at all, but instead felt an inexplicable sense of intimacy.

After being left in the wilderness of barbaric and backward for five days, he finally returned to the power era with his own efforts. With just a prototype, it was always a very good start and a perfect sign!

After the vegetable culture medium was added, the originally empty shelter seemed crowded at this time, and the placement of various furniture and items looked a bit chaotic.

Lu Yan frowned. The problem facing him now was... He had to redesign the layout in the shelter and maximize the use of the space as much as possible!

"But I don't have the experience and skills in interior design. It seems that I have to ask someone to help draw a design drawing." Lu Yan was silent for a moment and silently hung an item message in the trading yard.

Use a [Excellent]-grade axe as a product and exchange it for an internal design drawing of the power refuge!
Chapter completed!
