Global Famine: My items can be automatically upgraded.

Whether others can see it or not, Shen Bei is not an omnipotent god and cannot see through other people's thoughts.

But Shen Bei could tell that the double-winged viper must be a veteran actor.

Although we don’t know what means Youfeng used, it might be smell induction, or light fluctuations, etc.

But from the wounds on the double-winged viper's body, it can be seen that the new wounds cover the old wounds, and the old wounds penetrate deep into the skin and flesh.

To put it bluntly, with You Feng's means, he can definitely get rid of this double-winged viper.

And You Feng allowed this ferocious beast to live for so long that it still had the energy to continue attacking the farm.

From this, it is not difficult to see that You Feng is deliberately trying to improve his reputation in front of everyone.

Whether it should be said or not, this is also a means of ruling.

Only when there is crisis can there be influence.

It’s just that Shen Bei thinks it’s a bit childish.

When faced with Shen Bei's exposure, You Feng just smiled silently and didn't say much.

He was able to climb to the position of leader of the shelter without being embarrassed by other people's words.

The two of them stepped into the elevator outside the building. There was a sharp creaking sound as the elevator slowly climbed up.

They first reached the top floor.

Barley is grown here.

Barley is very suitable for planting on barren land because of its characteristics of early maturity, cold resistance, salt resistance, low temperature and coolness resistance, and barrenness resistance.

Because of the use of excellent radiation-mutated seeds, the barley in the sky farm can mature three times a year, and about 200 kilograms of barley can be harvested per acre of land, and 600 kilograms of wheat grains can be harvested in a year.

Shen Bei glanced at the wheat field. Since the ceilings of the upper floors had been completely demolished, the space above his head was very open, and the daytime sunlight could shine on the wheat field without any obstruction.

A lighting system that simulates sunlight is installed above the wheat field, which can provide light for the wheat seedlings in rainy and other weather conditions with poor lighting.

There must be no furrows in the plowed land for growing barley, and the ground must be flat, so the ground in the wheat field is flat.

At this time, the barley is just seedlings and has not yet produced ears. It is a tender green color full of vitality, and water can be squeezed out of it if you pinch it.

Shen Bei stroked the barley with his hand. It was these plants that fed millions of people. They were the cornerstone of human civilization.

But chemical fertilizers are still needed. Only by using chemical fertilizers can we grow more food with less manpower and free up manpower from the land.

In the old days, the fact that World War II could be waged on such a large scale was largely due to the fact that fertilizers and agricultural machinery liberated farmers from the land.

He walked in the wheat field and found that the automation rate of this aerial farm was not low. There were pipes laid on the ground, and the control chip would automatically control the sprinkler system every once in a while to spray water mist to irrigate the barley.

“How many people would it take to look after such a piece of land?”

After estimating that the area of ​​the farmland was about 4.5 square meters, about acres, he thought about it, turned around and asked You Feng who was standing behind him.

"The lower level requires a bit more people, fifteen, while the higher level only needs less than ten."

You Feng is most proud of his farm, so he naturally tells everyone about it.

“Why do we need more people at the bottom?”

Shen Bei asked with some confusion.

"Because the wind often blows weed seeds into the fields, these weeds grow very quickly due to radiation mutations and compete with the barley for nutrients in the soil, so they need to be removed promptly. If no one cleans up the wheat field for three days, it will be overgrown with weeds."

As You Feng spoke, he squatted on the ground and pulled out a weed seedling that was taller than his feet from the soil.

"This is Cyperus sedge. Its roots release toxins that kill other nearby plants. If we don't pull it out today, it will grow to half a person's height tomorrow. The barley nearby will be poisoned by it, and even the soil will need to be steamed before it can be used for planting again."

"As for some pests, they also need to be caught manually. Once the barley ears grow, many birds come back to eat them, which requires a lot of manpower."

"Of course, there are also reasons for the workers' laziness. The whip and the rice bowl must not be lost."

"If they can't even eat enough food they grow, they'll naturally become lazy."

As Shen Bei spoke, he squatted on the ground, pulled out a piece of weed, and crushed it in his palm.

You Feng coughed.

"Harvesting is when manual labor is most needed. When the flag leaf of the barley begins to turn yellow and the other leaves begin to dry, it enters the waxy stage. This period lasts only 37 days, so we must hurry up to harvest and dry it. Because the moisture content of the newly harvested barley exceeds 30%, it is very easy to germinate, mold, and rot. It needs to be aired promptly and harvested when the moisture content drops to 14%. Because time is tight and manpower is insufficient, sometimes we have to pull in guards to rush the harvest."

Shen Bei nodded.

"It seems you have plenty of water."

"Drinking water is naturally produced on Titan, and surface water has been treated to reduce radiation levels to a tolerable level. This water is used to irrigate farmland."

"What about electricity?"

"I have a large turbine generator here. Normally, we use barley straw to generate electricity, which we store in high-energy batteries. It can last for a long time."

Shen Bei's eyes lit up. A turbine generator is a very complex generator. Any combustible material can be used to drive it. Even leftover bones and unwanted fur can be stuffed into the boiler. The only difference is the power generation efficiency.

I didn’t expect Shelter No. 15 to be so good at recycling.

After a tour, Shen Bei became more interested in the area where soilless vegetables were grown. This area provided vegetables for the middle and upper classes of Shelter No. 15, and he believed that You Feng would be more willing to invest money in it.

The soilless vegetable cultivation area is on the fifth floor. The outer walls here have not been knocked down and remain intact.

Shen Bei pushed open the door and found that the empty room was neatly equipped with 35 rows of twelve-layer vegetable planting racks. The translucent glass troughs were full of cabbage, day lily, spinach and okra.

Each layer of the cultivation rack has its own lighting system that simulates sunlight to provide light for the vegetables. There are even silent small fans installed in the planting troughs to provide the vegetables with sufficient oxygen and carbon dioxide.

"This advanced soilless cultivation rack is mainly used to grow radiation-free and pollution-free vegetables for residents of status and value."

You Feng raised his chin and introduced, "Workers who come to work here must wear latex gloves, head coverings, and full-body outerwear to prevent pathogens from contaminating the plants. There are also 360-degree cameras that monitor the workers' work and prevent them from stealing and eating vegetables."

Shen Bei looked at the culture tanks. The vegetables inside were planted extremely densely. It was impossible for ordinary vegetable fields to reach this density.

He reached into the culture tank and pulled out a carrot.

After wiping the culture medium off his clothes, he put it in his mouth and took a bite.

It was very crispy, juicy, and had a sweet taste when bitten. It was even much better than the carrots he had eaten in his previous life and could be eaten directly as fruit.

He finished the carrot in his hand in a few bites and wiped his hands.

It’s really good!

The Chinese really love farming in their bones.

Maybe, Tiangong can also do this thing...
