In the Sky City in outer space of the earth, Li Fu and Chen Bin sat on mobile chairs and followed Luo Xiaoyao to visit the entire Sky City.

Because it is only affected by microgravity, there is no difference between up and down, front and back, etc., in the entire Sky City, and from time to time, there are other staff members driving mobile chairs on everyone's heads, and they can see each other when they look up.

"At present, the area where we are located is the space port area, which has been fully completed and put into use, with 8 space port terminals, each terminal is more than 2,000 meters long, and can park hundreds of "Hercules" aerospace aircraft at the same time, if it is a small aerospace aircraft, the number of berthing is even larger. ”

Luo Xiaoyao led the way in front and gave a detailed explanation to Li Fu and Chen Bin.

Li Fu is naturally very clear about the detailed data of the space port, and he can even memorize it, but at this time, when he really came to visit space, the whole person still felt very novel, and from time to time he watched outer space through the thick tempered glass, and from time to time he had to ask this and that, which seemed very curious.

"From this position, you can see our Tiangong space station in Huaxia, but if you want to see it clearly, you still need to use a telescope."

Luo Xiaoyao handed Li Fu a pair of binoculars, pointed to a window and said.

Li Fu looked in the direction with his glasses, and a huge space complex appeared in the field of vision, the scale of the "Tiangong" space station was already very huge, and the space capsule after section built a very large group, and the overall volume of the city in the sky was far beyond Li Fu's.

"The Tiangong space station has tens of thousands of space capsules, of which more than 90% of the large capsules launched in the later period, a space capsule is more than 50 meters in length and 5 meters in diameter, all of which are transported into space by large aerospace aircraft.

Luo Xiaoyao said very proudly, although he is now working for Li Fu, but after all, he is a person from the army, and his patriotic feelings still overflow.

"It's really amazing, tsk, I have seen dozens of this space plane here in the Tiangong space station alone, basically every once in a while, there are space planes flying over from the ground, and there are space planes flying to the moon or the earth, very busy!"

Li Fu nodded, handed the telescope to Chen Bin, the "Heavenly Palace" is now the largest man-made complex in the entire space, and Li Fu's Sky City is not half a star compared to it.

"It's huge, it's huge, but it's still built in an old-fashioned space capsule mode, and the use of space is still very poor, although our Sky City is far inferior to it as a whole, but the future development should be better."

Chen Bin also nodded after reading it, and expressed his opinion after a slight sigh.

"Lao Luo, take us to other areas."

Li Fu smiled and shook his head, and began to inspect again.

"This is our living area, which is mainly used for resting and exercising in space."

Soon, everyone came to the living area of Sky City, and in each room, some people were sleeping in the sleeping pod, and some people were constantly doing some mechanical stretching exercises, and the number of people was still quite large.

"Because there is no gravity in space or only affected by microgravity, so the bones of the human body will appear a little redundant in this case, if you stay in space for a long time, the bones of the human body will be in a relaxed state for a long time, the calcium in the bones will be lost, and once you return to the ground, you will be completely paralyzed."

"Therefore, in space, astronauts must insist on exercising for at least 2 hours a day, and the exercise method is to use mechanical stretching, which can greatly slow down the loss of bone calcium, and when they return to the ground, they will not become disabled for life."

Luo Xiaoyao explained to a group of astronauts and scientists who were sweating the importance of exercising in space, and that human bones evolved because of the gravity of the earth and needed bones to support their bodies.

"Lao Luo, the supervision work in this area must be done well, and we must insist on exercising to the specified time every day, and the other is that the time spent by our company's people in space must be formulated to a reasonable range, and it is best not to stay for too long, and after a few days, we should replace people and return to the ground."

Li Fu nodded after listening, and then thought about it carefully and told Luo Xiaoyao.

"I understand."

Luo Xiaoyao nodded, and was also very touched that the boss cared so much about the health of his employees.

Soon, everyone came to the agricultural area again, just entered the agricultural area, the eyes full of green suddenly came into view, rows of shelves here, all kinds of crops grow very well, many have blossomed and fruited, fruitful.

"This rice, it's incredible, it can produce several ears of rice, this should be genetic technology?"

As soon as Chen Bin, who was born in the countryside, saw a piece of golden rice in the agricultural area, he hurried over and looked at it carefully, and then the whole person immediately exclaimed.

He has seen a lot of rice since he was a child, and when he was a child, he also followed his parents to work in the farmland, and there is only one ear of rice for rice, which has been a thing since ancient times, but now the rice seen in space is like corn, and a node blooms an ear of rice, and a rice plant has several ears of rice, which is really unbelievable.

"No, all the crops here are pure and original, definitely not genetically modified crops, this is the same for rice, it is also a very ordinary seed, and it is not even hybrid rice."

Hearing Chen Bin's words, a man in a white coat who was carefully studying crops next to him came over and replied with a smile.

"You're Gu Feng, right?"

When Li Fu saw him, he recalled carefully in his mind, and immediately knew his detailed information, a high-achieving student who graduated from biomedical science from Imperial Capital University, and was also a scientist at the Institute of Biological Sciences of Fuyun Science and Technology Research Institute, and now the most important thing is to study biological gene technology.

"Brother Fu."

Gu Feng was slightly moved in his heart, he didn't expect Li Fu to know about himself.

"Gu Feng, since it is a primitive crop, why does this rice undergo such a huge change after it reaches space, it can actually produce an ear of rice at every node, which is absolutely impossible on the earth."

Chen Bin pulled out a rice plant, observed it carefully, and carefully counted the amount of rice on each ear of rice, took the millet in his hand and rubbed it to try the fullness of the millet.

He was surprised to find that the number of millet on these rice ears reached more than 150, and generally there are at least three rice ears on a rice plant, so this rice plant has 450 millet, which is more than twice the yield of the highest yield hybrid rice on the earth.

In addition to the greatly improved yield, Chen Bin also found that these rice grains were very full, almost all of them were very uniform, and there was no doubt that they were the best rice.

"We haven't fully figured out this phenomenon yet, in fact, not only rice, but also wheat, corn, sweet potatoes, etc., have very high yields in space, and they are generally several times higher than those planted on the ground, and some are like some vine crops, and the yield is even higher and scary."

"Look at this bean, it is more than ten times more productive than on earth; This is watermelon, its yield is more than ten times higher than that on the earth, and there are like pumpkin, winter melon, cucumber, etc., the yield has generally increased more than ten times, and the quality is very good, the taste is good, the nutritional value is extremely high, and it is definitely the top agricultural product. ”

Gu Feng nodded, and began to explain in detail for everyone, everyone followed his explanation and looked over, a green bean plant has a lot of branches, each branch is full of green beans, the vines of watermelons spread a large area, and the huge watermelons are quietly suspended, even people who don't understand agriculture at all know that the yield is very high.

"It must have something to do with the fact that there is no gravity in space, right?"

Li Fu touched his chin, these crops and so on Li Fu has been used to seeing since he was a child, and he also helped his parents with farm work when he was a child, of course, he knew that the yield of these crops on the earth was definitely not so terrifying.

"Well, at present, it can only be attributed to the changes that occur in the environment of space that is not affected by gravity, or microgravity, of course, there is also a very important reason that we are all cultivated according to the needs of various crops, how much water, how many nutrients, how many nutrients are needed, and so on."

"Of course, another reason is that this is space, and the sunlight is very abundant, even if the light is 24 hours old; In addition, there are no pests and diseases in space, and there is no need for pesticides and so on. ”

"The combination of many factors makes the yield of crops so high, and the quality is very good, and the crops produced taste very good and have high nutritional value."

Gu Feng nodded, pointing out the advantages of high yield, high quality, and pollution-free crops in space.

"In this way, space agriculture is really promising, even if the cost of transporting water resources is not cheap, but once this yield is raised, it is a high-quality crop, and there is still a lot of profit margin."

Luo Xiaoyao, who had not spoken on the side, couldn't help but nod at this time, and calculated carefully with his fingers.

"Of course, there is a lot to be done, the space in space is unlimited, the sunlight is unlimited, as long as the space is used well, the time and location are arranged, the output value of crops will be very high."

Gu Feng nodded, and said in a natural tone, obviously very optimistic about space agriculture.
