"Why do you believe me, then the world itself is built on the basis of trust, you don't believe me, it's really useless."

"Hahaha, you have no basis for what you say." Wu Zhuo pointed at Wang Yufei: "But it's not impossible to bet, if you don't do it, leave the village with Xiaohong, and you can live your little life." ”

Sister Hong frowned, then turned her head sideways to look at Wang Yufei, and finally gritted her teeth and said loudly: "Yes!" ”

Someone next to her immediately persuaded her, but Sister Hong didn't care at all, she just stood there with her neck held high and confronted this open-mouthed Wu Zhuo.

Wang Yufei pursed his lips: "Okay, what if I become it?" ”

"Then I'll go!" Wu Zhuo can be regarded as a man.

At this time, Wang Yufei shook his head: "You are a lot older, how can you support yourself when you go out, you can't do it." If I really succeed, you can apologize to Sister Hong in front of the big guy, okay? ”

"Okay! Then I'll wait for your good news. Wu Zhuo snorted coldly and brushed his sleeves away.

After a while, the people watching the excitement were almost gone, and Sister Hong looked up at Wang Yufei: "Thank you......"

"Don't thank me, it's time to get to work. You've been busy these days. Wang Yufei turned around and looked at the mountains and forests behind him: "Pull a cordon, don't come in except you." ”

"Okay."

Sister Hong's execution is very strong, she immediately took people and started to work, but at this time, 2πr asked curiously: "Why did that person say he wants to leave, but you want to leave him instead?" ”

Wang Yufei dragged down a weed leaf and tore it up: "You can't force people to a dead end, the dog jumps off the wall when he's in a hurry, you force people to rush him to the official report here, do you think this broken place can withstand it, can't stand it." Since we said that we have settled down here for the time being, we have to operate it carefully, otherwise the audience will give bad reviews. ”

"Understood, it's still you."

"It's not fine, why don't I take it out and show you?"

"Forget it, I have it myself." 2πr replied earnestly.

The next work is actually very simple, build a simple greenhouse, water grow seeds, set up a strong light, and then simulate sunlight through a filter tape, and the most important thing here is genetic modification and making culture medium.

Someone once asked Wang Yufei, that is, why is the world you are in already worry-free, why are you still so hard-working. At that time, he forgot how he answered, anyway, the general meaning was that he didn't want to eat the food that was spurred by gene editing technology and fortified growth fluid, he wanted to eat lobsters caught in the sea, he wanted to eat old hens that were a year and a half old, he wanted to eat vegetables with natural insect eyes, and he wanted to eat rice grown in the soil.

These are all money-intensive, and very expensive, and that's why he's been playing with his life.

But now it's different, as 2 said, the greatest invention of this era is what he once didn't even want to look at, vegetables with insect eyes can't feed so many mouths, and rice grown in the soil can't meet that big demand.

According to his requirements, Sister Hong built a hydroponic farm with about two acres of land, although the conditions are simple, but fortunately, the current season and climate are not bad, so there is no need to worry about the temperature.

In fact, anyone who sees it will feel worried, even if two acres of land can be formed in 21 days, what can it be? Whether you can grow something or not is not the most important thing, what you really have to worry about is how many things you can grow.

However, Wang Yufei didn't care about this at all, he built ten layers of planting with wooden shelves and wires, planted different crops from high to low, and then used the industrial waste that Sister Hong usually picked up to make an automated irrigation and lighting system, and the whole process only took two and a half days.

The most important thing here is the configuration of the core nutrient solution, which is definitely enough to kill the invention in this era, it can make crops grow ten to fifteen times more efficiently, as long as the nutrition keeps up, the crops that originally took 90 to 120 days to mature can be fully matured in just about ten days.

But don't expect the taste and taste, just say that the nutrients that should be there are all the nutrients, not delicious but definitely not starving to death.

In terms of biology, it is mainly for the embryo of the chicken using nanorobots to modify its growth genes, so that these chicks out of the shell have a very strong growth ability, if everything goes well, twelve to thirteen days can enter the stage of sexual maturity, so that the second generation of chicks after some improvement, so that they take into account the characteristics of broilers and laying hens, so that when the third generation, a square meter of breeding density can reach twelve, and then use the high yield of hydroponic crops, soon to solve the food problem.

This set of operations is not Wang Yufei's own figured out, this is his world's "natural disasters and pioneers self-rescue preparedness plan" clearly described, 21 days for a cycle, every 21 days to double the production scale, double the output efficiency, double the output difficulty of the 21111 project plan.

This thing is no different from the practice of immortals in the eyes of people who can't understand it, but in fact, it's just a scientific task, and even in the elementary school at that end, relevant courses have been carried out.

Sister Hong was also very apprehensive at first, he had to come and sit here and watch those hydroponic boxes for a long time almost every day.

On the first day, she saw the seeds sprout, and she felt like she had given birth to a baby, excited and uneasy.

The next day, the seeds that had only sprouted yesterday had already taken shape today, and they were lush, and the chicks next to them began to chase around.

On the third day, she was stunned by the growth of the crops, and the grain crops had even begun to bloom, and the melons and fruits had begun to climb the vines, a speed that he could not have imagined.

By the fifth day, the whole temporary greenhouse had completely changed its appearance, like a forest, and the seedlings at the bottom had begun to tassel, although they were not yet fully formed, but they did already have that appearance. Other crops such as pumpkins, sweet potatoes, potatoes, etc., can be eaten even if you are in a hurry.

And the watershed on the fifth day was not only these, those chicks that were still fluffy had already shown the characteristics of feathering, and the average weight was about 300 grams.

"Doesn't it look like a demon spell?"

When Sister Hong looked east and west, her eyes were full of surprise and puzzlement, Wang Yufei opened the pumpkin vine and appeared in front of her. At this time, Wang Yufei was holding a teacup in his hand, and he didn't know what was brewing in it, exuding a bitter taste.

"Yerba mate." Wang Yufei stepped forward: "I see a lot of them on the mountain, do you want to drink?" ”

"On the mountain?" Sister Hong was stunned for a moment: "There are no tea trees on the mountain." ”

Wang Yufei pointed to a common tree: "That, green belt." ”

Sister Hong laughed, then sat on a wooden stool next to her, and looked at Wang Yufei with interest: "Are you really a mechanic?" How I feel like you know everything. ”

"Haha." Wang Yufei laughed, he walked to a pot of hydroponic plants, broke two cucumbers and handed one to Sister Hong: "Look here, is it revealing the beauty of industry everywhere." ”

It's true, although this is a sea of green, whether it is the fill lights on each shelf, the wooden shelves built at different angles, or even the faucets that are ticked every few minutes, all show the charm of industry.

"yes."

"That's right, these fruits and vegetables are actually the end products of an industrial industry chain. It includes mechanics, automation, hydraulics, chemistry, biology, and so on. A good mechanic has all these knowledge. ”

"Really...... Is it mandatory? Sister Hong was stunned by him: "Where did you learn machinery?" ”

"I studied medicine at the Hama Medical College in Yujia, and mechanics at Rika New City."

These two terms need to be interpreted in particular, Yujia Hama and Rika are the names of alien civilizations, the names are transliterated from the pronunciation of their civilizations, although they are invaders of the earth, but they also open the door to the external communication of the solar system, although this opening method is not very good is created with particle cannons, but it is finally opened.

Before the serious start of the war, there was actually a period of relatively peaceful exchanges between the parties, and during this time, many earthlings went to study with them in order to pursue "civilization".

But after the war, now the bilateral ports have been temporarily closed, and no one knows when they will be opened.

"Ahh It turns out that you are an international student! No wonder, I just said......"

Sister Hong suddenly became excited: "They must be very advanced, right?" ”

"Want to go?"

Sister Hong shook her head directly without even thinking about it: "I don't want to, I just hope that when we can be as good as them here, then we won't have to be bullied." ”

"That's right." Wang Yufei replied: "That's why I came back." ”

Sister Hong nodded vigorously: "As long as there are more people like you, the dream will definitely come true." ”

"When the time comes, I'll write a letter of recommendation for you to go to medical school."

"Haha......" Sister Hong smiled very happily, her eyes had been bent into a crescent moon: "I may not be able to live to that time, but I hope that day." ”

"Yes." Wang Yufei raised the teacup in his hand: "You will definitely live to that day." ”

The two chatted for a long time in this verdant and closed vegetable field, listening to Wang Yufei describe the future in reverie, Sister Hong's heart was full of longing, although she has nothing now, and she doesn't even know how long she can live, but at least now a seed has been planted in her heart.

As for Wang Yufei, even Sister Hong felt that what he said was a romantic reverie, but he didn't care about it himself, because what he described was the world he grew up in. Although he would complain a few words from time to time, but when he looked back at Sister Hong's side, he actually felt that his world was actually the Heavenly Hall.
