On March 15, the materials sent by the exchange arrived one after another.

The twenty-acre glass greenhouse has officially started construction.

Zhang Nan and relevant agricultural experts designed the greenhouse into a rectangular structure of 32 meters wide and 420 meters long.

A cement trough of one meter wide and two meter deep was dug around the edge of the greenhouse, filled with water, and placed a heat dissipation pipe extending from the steel mill, absorbing the heat from the pipeline to increase the temperature in the greenhouse.

In addition, the existence of the sink also blocks the low temperature transmission of shallow soil, forming a relatively independent small environment.

There is no need to worry about power issues. Steel Town is a large power consumer. It has a supporting 3,000kw coal-fired power plant that generates tens of thousands of kW of electricity every day, and a few percent of it is allocated to greenhouses, which is enough to use.

There is also manpower. Zhangnan Farm can only draw 50 strong laborers. Usually, it is enough for greenhouse management, but there is definitely not enough manpower to build a handicraft work like greenhouse construction, and it is dangerous.

So Wu Zebin specially dispatched 300 steelmaking workers to provide a lot of materials and equipment, and spent a day helping to complete the construction of the greenhouse.

Pull the wires and install the lighting system.

By March 21, this 20-acre greenhouse was officially put into use.

Zhang Nan led his men to plant the first batch of five acres of vegetables, and the rest were arranged one after another.

Of course, since there are not many white light balls left in the body, the area of ​​vegetables planted after being blended into the white light particles is less than five cents of the ground and the area is not large.

"Angkor, I've helped a lot. Without your help, this project wouldn't be done."

Zhang Nan shook Wu Zebin's hand and said thank you.

"Brother Zhang, you obviously helped me a lot, I should thank you."

Wu Zebin didn't quite understand Zhang Nan's brain circuit.

In this winter, the farmer didn’t hide in the house, but a few of them ran outside to make trouble.

But this guy's enthusiasm for farming was beyond imagination. He ran to other people's homes, borrowed other people's territory, and helped others solve the problem of eating vegetables and fruits in winter, but he could only get 40% of the rewards and had to be responsible for long-term management.

By the way, this kind of low reward for giving is called "burning oneself and illuminating others". Apart from Zhang Nan, who else is willing to do it?

Anyway, he didn't understand it very much. If he had built a 5-cent-sized land at home, he would be enough to be self-sufficient. There was no need to make it so big.

Perhaps, I can only explain it with love.

...

After planting the first five acres of vegetables.

Wait until all the fruit seeds are in place.

Zhang Nan led his people to plant 3 acres of strawberries, 3 acres of watermelon, 3 acres of melon, 3 acres of grapes and 3 acres of red-skinned sugarcane.

sugar cane?

What are you doing with this thing?

Because sugarcane is also a C4 plant and has high photosynthetic efficiency, Zhang Nan planned to plant a batch and see it. Even if some people expressed doubts, as the manager of the greenhouse, Zhang Nan had the right to decide what to plant.

When all the above things are done, it is already the end of March.

Zhang Nan has two households and has been staying in greenhouses for a long time. If you have any questions, you can report through pager messages (yes, the Ministry of Science and Technology Industry has mass-produced a large number of pagers, which can be operated in a fool-like manner and sent voice messages). Usually, Zhang Nan goes there every two days, and even goes there every day.

...

At the end of March.

In fact, there is another thing that happened.

The natural gas pipeline construction and laying team passed by Zhangnan's farm.

Although Zhang Nan had also seen the world, he was surprised that day. As for the native workers in the farm, some were speechless, some were kneeling on the ground and bowing, and some were divine, as if they had seen a god, and their behavior was very unbearable.

Automatically laying of self-propelled engineering vehicles for pipelines.

It weighs at least 3,000 tons, has a length of more than 100 meters, and is at a height of ten floors. It has multiple turrets installed on the upper floor, and walks with two huge tracks, and it slowly advances at a speed of five kilometers per hour.

This speed seems very slow, but don’t forget that it is digging the trench in front while the process is carried out, and the connected natural gas pipeline is automatically placed behind it, and the trench is filled and slightly compacted, so that there is no obvious trace.

In short, it was all completed by this giant engineering vehicle, trench digging, burying pipes, welding, filling and other tasks in natural gas pipelines.

When you encounter a mountain, you will open a hole, and when you encounter a water, you will become a boat.

In one day, you can complete the pipeline laying task of hundreds of kilometers.

In another twenty days, you will be able to build the Great Wall defense line.

The work efficiency is simply amazing.

When I heard that Zhang Nan’s farm lacks fuel for winter heating, the giant machine stopped for a while, but did not open a valve air supply port on the pipeline. He directly pulled a hose to the town’s gas storage station. He connected a port from the giant self-propelled machinery vehicle to pressurize the gas reserves of the farm gas storage station to 100%.

Only then did Zhang Nan discover that the natural gas pipeline behind this giant engineering vehicle was kept in a ventilation state, like an unbroken energy line, providing the high-power gas turbine of this giant engineering vehicle with endless fuel and giving it surging power.

This is why it can move forward continuously.

"Thank you, please give me a headache!"

The problem of insufficient fuel in the farm was solved. Zhang Nanlianlian expressed his gratitude and was a little embarrassed. After all, it delayed them for nearly an hour and affected the pipeline laying progress.

"You're welcome."

The engineer said lightly, then got on the construction car, and the rumbling sound of rumbling forward quickly.

Looking at the giant engineering car that was like a mountain, moving slowly and moving away.

Zhang Nan had to admit that such giant construction machinery represents the pinnacle of human industrial capabilities. It not only shocked humans like him, but also seemed to see the gods in the eyes of the indigenous people on the farm, and his awe became even stronger.

For example, there is a 12-year-old indigenous boy named Prit, who not only has awe, but also has some kind of fanaticism and longing for something inside.

Of course, Zhang Nan knew what Prit was thinking, because it was this young man who was 10 years old and was crazy about the excavator on the farm. He begged Zhang Nan every day and said that he wanted to learn to drive the excavator. Zhang Nan was so annoyed that he gave him a chance to learn.

As a result, in just one year, Prit excavator was driving more easily than anyone else. Zhang Nan felt that he had become an excellent excavator driver and could get as many labor points as adults.

Today he saw a bigger and more shocking guy again, and he must have had some ambition. The small excavator is no longer very fragrant.

"Prit, do you want to drive such a big guy?" Zhang Nan asked the boy.

"I think so much!" The young man nodded repeatedly.

"Then learn the knowledge of engineering machinery and learn the basic skills of physics and mathematics well. As long as you have a solid basic knowledge, when you are 18 years old, I recommend you to go to the City University of Technology and Mechanical Sciences, which is a paradise where you will realize your dreams."

Zhang Nan drew a cake for the boy: "In addition to pipeline laying engineering vehicles, the Development Bureau is said to have railway laying vehicles, highway laying vehicles, tunnel drilling vehicles... all kinds of huge creatures will definitely have the opportunity to drive one."

"Boss, I want to study, I must go to the university you mentioned!"

The boy's dream was ignited, and he looked excited and extremely excited, just like some human children who knew that he had hope of becoming Ultraman.

"Work hard."

Zhang Nan smiled and knew that an excellent indigenous industrialist seedling might be born on his farm.

In fact, Zhang Nan is also a member of the Industrial Party, and is divided into the "Farming Industrial Party".

Among the naturalized indigenous peoples within the Kaituo Bureau, after witnessing various industrial miracles, there are many potential industrialists, and they even have a certain religious worship, yearning for the large scale, liking the beauty of industrial lines, and worshiping the power contained in it. If a certain industrial machinery can combine the great, beautiful and force together, it can really replace the position of the gods in their minds as a lifelong belief.

Among the nearly one billion naturalized natives who have developed a new development, the reason why they can easily resist and resist is that they are shocked and influenced by various industrial machinery. In addition, they live a good life. Compared with the past hell, they seem to have come to heaven, so there is almost nothing they can't think about.

but……

Since Blue Star was blew up by a sword.

Most of the pride and pride in the hearts of the human industrial party were wiped out by that sword.

The same is true for Zhang Nan.

Because the power level of Xuanmeng Continent is obviously much higher, no matter how the technology of human civilization develops, it will be difficult to easily destroy a planet even in a few hundred or thousands of years, but the power of Xuanmeng Continent has done it.

Therefore, in the face of real power, the technological or industrial strength of human civilization is only very competitive in the competition between the middle and lower levels. Once it reaches the high-martial level, the power of nuclear bombs may not be anything.

"My little power is far from enough."

In the fourth floor research room, a beam of light shone out at the top of Zhang Nan's index finger, shining on a special piece of metal called "Mijin".

Mijin is a special mineral belonging to the Xuanmeng Continent. It is quite rare and has a very high value.

Its melting point is as high as an astonishing 1 million degrees.

The density is 96 grams per cubic centimeter.

It has extremely high hardness, high toughness, corrosion resistance, and does not react with any chemical substances. It has the nickname "Immortal Gold" and cannot even be smelted and processed.

Therefore, in Xuanmeng Continent, the main value of Mijin is as a valuable currency and has very few other uses.

Zhang Nan had a total of 6 pieces of gold in his hand, with a total weight of 53.3 kilograms, the largest of which was the size of a baby's fist.

These secret golds were exchanged for the vegetables in the vegetable greenhouse when he was stationed in the 2891 bastion before. The refugee camp lacked everything, but there was no shortage of all kinds of precious treasures.

However, the true value of Mijin was only truly discovered in January 2032 (two months before Blue Star was destroyed), causing a huge sensation and carnival in the scientific community.

catalyst.

Mijin is a magical metal that can eliminate coulomb forces between atomic nuclei and thus reduce the reaction temperature of nuclear fusion to 1 million degrees.

Scientists also discovered that the mass of the sun above the Xuanmeng Continent is only one-tenth of that of the sun on the Blue Star, but its brightness is eighty times that of the Blue Star Sun, and it can also perform elliptical motion at a speed of 0.5 times, which is completely inconsistent with scientific common sense.

Scientists have uncovered the mystery by the discovery of the nature of secret gold. It turns out that the sun in Xuanmeng Continent contains a large amount of secret gold, which greatly accelerates the rate of nuclear fusion reaction. When the sun is about to burn out in 500 million years, the god will replace it with a new sun.

The burned sun turned into countless wreckages, abandoned like a meteor shower in every corner of Xuanmeng Continent, with precious secret gold resources collected by the natives.

Then a few of them came to Zhang Nan's hands.
Chapter completed!
