Finally contacted Earth, you said not to answer?

Chapter 10 Compost
  stool.

Fertilizers have been used by humans since ancient times and are very important even today.

usually.

Manure is rich in various trace elements such as nitrogen, phosphorus, calcium and potassium, which can provide sufficient nutrients for crops so that they can thrive.

This theory also applies to aliens.

In fact, Wang Wei had tried it before, but because it was not the powder season at that time, the result also failed.

Base field.

Wang Wei frowned at the sight of the sack full of "goods".

It can only be said that even the smell of an alien's defense is not much different from that of the earth. It smells the same.

Now that the fertilizer needed for the alien potatoes has been obtained with the help of Brother Shu, the next step is to fertilize.

He first covered the potatoes in the field with part of the manure to ensure that the alien potatoes could successfully end dormancy and enter the growth stage.

The rest is prepared to compost the manure the same way Earth does with farmyard manure.

There is no reason why the experience accumulated over thousands of years on earth would be worse than if it were allowed to grow wildly.

Let Da Vinci carry an iron can.

Pour in all the remaining feces, mix it with water, mix it with the soil on the planet, and seal the lid.

Finally comes the most important part.

That is, high-temperature compost fermentation.

The high temperature generated by the natural fermentation of feces kills insect eggs and grass seeds in the feces, and finally the feces is decomposed by bacteria, so that it can be used as fertilizer after treatment.

Fertilizer treated in this way has two benefits.

First, the fertility is fully utilized, which is more conducive to plant absorption and growth.

Second, grass seeds and insect eggs have been killed by high temperatures. After fertilization, there will be no parasitic pests or weeds competing with potatoes for nutrients.

As a major agricultural country, it is even one of the earliest birthplaces of farming culture in human history.

Dongxia always has an inexplicable obsession with farming.

So much so that after Wang Wei settled down on the alien planet, he immediately opened such a piece of farmland.

I always feel like there are no crops growing in the fields, and I feel uneasy.

Just like Americans first think of hunting, this is a subconscious influence brought by culture.

The process of compost mixing is painful.

At the very least, Wang Wei was in pain.

Da Vinci just repeated the stirring action mechanically, not understanding why Wang Wei's expression was twisted like this in pain.

Fortunately, it's finally over.

Seeing Wang Wei leave here as if running for his life, Da Vinci just tilted his head curiously and continued to finish the work.

Generally speaking.

The compost fermentation process takes a full half a month.

When the fertilizer matures, becomes dark brown in color, and shrinks in size by about one-third, it can be covered on these alien potatoes.

But Wang Wei didn't really have enough time, so he could only shorten the compost fermentation time to one week.

Next.

Just need to wait.

……

Seven days passed quickly.

Da Vinci came to the base field as promised and opened the sealed tank of compost.

Wang Wei watched from afar.

As the lid of the sealed iron pipe was lifted by Leonardo da Vinci, it seemed as if a demon ran out laughing wildly. Even though I was far enough away that I couldn't smell it, I still couldn't help but hold my breath when I saw the scene in front of me.

On the contrary, Da Vinci looked indifferent and seriously covered the potatoes in the field with fertilizer.

Wang Wei's previous PUA was very successful.

Da Vinci not only had no objection to his current work, but had a sense of mission to be trusted.

This is not fertilizing potatoes! This is saving Wang Wei’s life!
  Until the fertilization is finally over.

The devil was sealed back into the cage again.

Wang Wei still kept a certain distance from Da Vinci unconsciously.

There was nothing I could do about it. After such a long day of work, Da Vinci's iron sheet was almost pickled.

Although he recognized the work of Leonardo da Vinci's children and was very moved by his efforts.

But the smell is still overwhelming, and the subconscious avoidance is purely a physiological reaction. It’s not that I hate Leonardo da Vinci’s children.

While speaking, Wang Wei calmly took a small step back.

In fact, he was not idle during the seven days waiting for compost.

The matter of contacting the earth has always been on his mind, and he has not forgotten the failure of the ninth generation communication device.

It's just that because the food problem was really imminent, I never paid attention to it.

Now the problem of growing alien potatoes has finally been solved.

While the compost was fermenting for seven days, Wang Wei and Leonardo da Vinci studied the reasons for the failure of the ninth-generation communication system.

"The signal strength of ninth-generation communication devices is completely sufficient."

"At least it should be enough to spread to the earth."

Wang Wei was confident when he said this, perfectly demonstrating his confidence in his own technological level.

What a joke.

He has almost completely mastered the technology of this alien spacecraft. If he doesn't even understand the communication device he built, then he might as well not even think about going home.

"But since the signal has been transmitted to the earth, what is the reason for the failure?"

Wang Wei muttered to himself, then turned his head and saw Leonardo da Vinci fishing in a daze.

He now seriously suspected that the three-year-old Leonardo da Vinci had entered the rebellious stage.

Come to think of it, it's definitely time.

His personality has been almost established in the past three years, and the next step is to evolve from an artificial intelligence to a truly intelligent life.

He is always thinking in a daze, and he doesn't know what is going on in his head.

The most important difference between robots and humans is actually here.

It is not the so-called emotion or wisdom, which can be simulated through calculation.

The most important difference between robots and humans is actually their ability to think independently.

This is the evolution from everything being meaningless to everything being meaningful.

The obedient and sensible little robot before was about to leave me, which was really sad.

Wang Wei sighed with emotion, still sincerely happy for Da Vinci's change.

"Since there is no problem with signal strength, is it a problem with stability?"

When Moyu was in a daze, his head was knocked by Wang Wei. Da Vinci came back to his senses and put forward very constructive suggestions.

It was strong enough to spread to Earth.

But if the stability is insufficient, when the signal reaches the earth across the vast universe, it is likely to become a meaningless messy sound due to interference from cosmic radiation.

Wang Wei looked at the design drawings in front of him thoughtfully, turned his head and said to Da Vinci seriously:

"Da Vinci, you are a wise man."
