The space chair Zhang Lu was riding in slowly slid out after completing the security check along the security track, and finally entered the gate through the No. 12 exchange module of the leaf space station, where everything was very quiet.

"Welcome to the Leaf Space Station, Miss Zhang Lu!" The beautiful waitress gave Zhang Lu a charming smile.

"Thank you!" Zhang Lu was still sitting on a chair and looking around curiously, when she suddenly noticed that behind the two robot guards, a girl hurriedly floated over this way.

"Welcome, Miss Zhang Lu, it's a pleasure to meet you. I'm Dorothy Hill, secretary to Deputy Commander Sarah Mitchell of NASA. The tall young girl came to Zhang Lu and said politely, dressed in a black suit, a pair of black-rimmed glasses, and a ponytail.

After Dorothy finished speaking, she smiled politely at the waiter next to her, then looked back at the curious Zhang Lu, and waited quietly.

"Hey!" Zhang Lu didn't bother to look at Dorothy at all, her attention was completely attracted by the luxurious sci-fi silver world here on the space station.

The Alpha Square gate of this space station is very wide and bright, and it looks like it is at least a kilometer long. In fact, visitors to a total of 18 exchange chambers in Alpha Plaza eventually converged to enter the plaza gate. At the eastern end of the busy Alpha Gate, dozens of large trains stopped on the platform, stopping and departing from time to time, all clearly marked with the word "freight" on the outside.

In the open area in the center of the gate of Alpha Plaza, there are all kinds of colorful spherical cars parked here, which are smaller than the Beetle space car, and the dazzling spherical cars are constantly shuttling around, they stop and leave in an orderly manner, and it seems that this place is bustling.

Finally, Zhang Lu reacted, looked up and smiled at Dorothy, and then stumbled and pushed the elastic arm of the space chair hard.

"Be careful!" After Zhang Lu pushed away the elastic arm of the space chair, because she was in a weightless state at this time, her body floated directly to it, and Dorothy quickly grabbed Zhang Lu's left foot and pulled her down.

"Oh! Thank you! Zhang Lu still hadn't entered the state, she looked around with a smile and felt a little excited.

The waitress smiled apologetically at Dorothy and Zhang Lu, and then said to Zhang Lu, "I'm sorry, you need to put on your space shoes first." ”

After the waitress finished speaking, she took out a pair of strange silver board shoes from the cabinet next to her, and as soon as Zhang Lu stepped on her feet, the board shoes immediately stretched out four hard straps to tightly clamp Zhang Lu's feet wearing shoes.

Zhang Lu then felt a gravitational pull sucking her feet to the floor, and then the waiter put a wristband on Zhang Lu's right wrist, and finally buckled a light belt around her thin waist, and the belt became invisible immediately after wearing it.

Zhang Lu magically found that her waist was also affected by the gravity from the spaceship at this time, which made her feel a lot better, basically the same as the feeling on Earth, because the feeling of weightlessness was really terrible for her.

"Have a great trip, this wristband can pick up your brain waves, and it can help you achieve any action you are trying to do here, such as walking or sitting, lying down, etc., depending on your wishes, and it may take you a few minutes to get used to."

"Thank you!" Zhang Lu smiled sweetly at the waiter, and then tried to lift her feet and turn to face Dorothy, but because she lifted too hard, she almost jumped 50 centimeters off the ground.

"Ah!!h Zhang Lu screamed, but the electric field of the space station immediately led the space shoes under her feet and the belt on her body back to the floor.

After Zhang Lu stood firm, she made a naughty face at Dorothy, "It's the first time I've seen you, it's an honor to ......"

Zhang Lu had just forgotten Dorothy's name because she was so excited, and she smiled a little embarrassed and couldn't continue.

"Dorothy." Dorothy immediately understood, and smiled generously to remind the other party again.

"Thank you for picking me up, Miss Dorothy." Zhang Lu said slightly embarrassedly while turning around and waving to the waiter.

"I heard that you came to report from the Lunar Academy of Natural Sciences, congratulations, you are really great! Well, we should go too, and I'll take you to Lieutenant Mitchell. Dorothy has a strong sense of time, she doesn't want to waste too much time here, so she turned around and led Zhang Lu to the spherical car in front.

After Dorothy finished speaking, she lowered her head and tapped lightly on her wristband, and then her feet slowly rose and hung in the air, about 15 centimeters above the ground, and then the whole person quickly slid forward.

"Quick, keep up!" Dorothy turned back to greet Zhang Lu.

"But...... I won't! Zhang Lu shouted with a wry smile.

"Think of it yourself, Miss Zhang Lu, you're a student of the Lunar Academy of Natural Sciences." Dorothy didn't look back, but slid straight forward, farther and farther away.

"Hey !!" Zhang Lu looked at Dorothy's back a little anxious and angry, and had to look down, and then carefully tapped the three-leaf fan symbol in the center of the watch.

"Crunch" Suddenly, the invisible space shoes on the soles of Zhang Lu's feet slowly rose off the ground, but they did not slide forward like Dorothy, Zhang Lu anxiously looked at Dorothy in front of her.

"Let's go!" She grumbled inwardly.

To Zhang Lu's surprise, the space shoes suddenly began to slide forward quickly according to her wishes.

"Too fast, too fast, slow down." Zhang Lu almost fell, trying to balance her body while silently reciting in her heart, the magic was that the space shoes seemed to be able to read her mind, and her speed of gliding immediately decreased.

"Hey, hey! I'm going to catch up with you, huh! After Zhang Lu mastered the basic performance of this set of equipment, she looked at Dorothy in front of her proudly, and then silently thought in her heart to let the space shoes accelerate towards Dorothy.

Because the speed was too fast, Zhang Lu involuntarily stretched out her hands to balance on both sides, and soon caught up with Dorothy and overtook her.

"Uh......h Hey......" Zhang Lu winked at Dorothy as she overtook her, cheering.

“Good Gi

l！ Dorothy smiled at her and chased after her

"Where are we going?" Zhang Lu finally followed Dorothy to stop next to a white spherical space rover and couldn't help asking.

"Area 99." Dorothy didn't look back, she pressed the wake button of the spherical car with her index finger, and then aimed her face at the scanning area in front of the spherical car's door, which began to slowly lift the door upwards after identifying her.

Dorothy didn't wait for the car door to be fully lifted and bent down to get in, Zhang Lu could see that Dorothy was an impatient, so she followed in.

There are four car seats in the spherical car, and Zhang Lu and Dorothy sit down facing each other and buckle their seat belts.

"Target, 99 District 34 Street 7, thank you!" Dorothy speaks voice commands to the system in the car, and a three-dimensional map of the destination is immediately projected in the center of the car, which disappears after about 5 seconds and finally becomes a three-dimensional map that slowly rotates 360 degrees in the air.

According to the map, Zhang Lu saw that they were a little more than 41 kilometers away from their destination, and it was estimated that it would take 15 minutes and 17 seconds. To Zhang Lu's surprise, she hadn't even felt any movement in the car, which had already shown a speed of 159.4 km/h.

"Well, then, I'll take a break first, if you don't mind, Miss Zhang Lu." Dorothy helped her black frames, looked at Zhang Lu, and then closed her eyes.

"Of course not, thank you." Zhang Lu looked curiously at the spherical rail cars shuttling back and forth outside the window, and they were running in an orderly and fast manner on the dense tracks.

When Zhang Lu thought that the spherical cars on these space stations were all using the nuclear batteries of their Hualu Group, she felt extremely proud.

After about 9 minutes, when the system showed that they were still 6 minutes away from their destination, the system in the car suddenly prompted them to enter the absolute gravity field area.

At this time, Zhang Lu obviously felt that her whole body had returned to the same state as on the earth, and she no longer only felt the gravity between her belt and space shoes and the floor, but her whole body was subjected to gravity from the ground. Dorothy's spherical car entered the space station's electric simulation of the earth's gravity field, this absolute gravity field area, people's activities are like on the earth's surface, all objects are subject to the same gravity as the earth, people can move freely without any auxiliary equipment, work and live normally. Of course, people can still use space shoes to glide in the air if they want.

When the spherical space rover finally arrived at its destination, Zhang Lu followed Dorothy out of the car, and looked up to find that three large characters were neatly written on the top of the gate in front of them: Space Agency.

Outside the gate of the space agency, there are quite a few space vehicles on standby, and from time to time there are people in blue overalls rushing in and out of the space agency.

"This is where Beibei dreams of coming and sending her some pictures later, that silly girl." Zhang Lu thought to herself.

Excited, Zhang Lu finally followed Dorothy into the space agency, in the long passage, the lights were bright, Dorothy nodded to passers-by from time to time, while explaining to Zhang Lu that the reason why there is a long passage here is because it is used for emergency isolation, this passage can deal with sudden dangers, and can quickly isolate the air and bacteria. On the Leaf space station, there are such emergency isolation channels for local units in each zone and between each zone, which guarantee absolute isolation and safety between each unit.

In the leaf space station, all the walls here are thickened titanium alloy walls, including translucent β alloy lighting ceiling wall glass also has triple protection, each layer of glass can withstand 15,000 atmospheres, it can easily resist general meteorite impacts, and minor meteorite impacts are usually just glass deformation, and will not be easily penetrated.

"Miss Dorothy, I have a question." Zhang Lu followed behind and asked suddenly.

"Please!" Dorothy slowed down, and they were passing through a hall where everyone was busy in front of their computers.

"Why are there areas on the space station that absolutely simulate Earth's gravity, while others are not?" Zhang Lu followed Dorothy, looked at her and asked.

"That's a good question, girl." Dorothy then came to the elevator door and waited for the door to open.

"The Leaf Space Station was jointly proposed and built in 2163 A.D. by the American and Asian continents, the Boling Continent and the Dori Continent, and it has not been completed for 12 years. The space power simulation gravity field technology here was only tested and applied 8 years ago, so the area built in the next 8 years of the leaf space station has been added to this technology, accounting for about 68% of the area of the leaf space station. ”

Zhang Lu listened carefully and then suddenly realized that she was usually not very interested in this, but she often heard Bei Bei talk about the topic of space and the universe, and now she was in the leaf space station, and it was only then that Zhang Lu really felt its greatness and incredibleness.

Zhang Lu thought for a while and then asked, "Then when will the Yezi space station plan be completed?" ”

Dorothy faced Zhang Lu's question, and after entering the elevator, she patiently continued to answer Zhang Lu about the background and design structure of the space station.

The Leaf space station is not expected to be fully completed until 2180, but this does not prevent it from operating ahead of schedule. The entire leaf space station is in an elliptical shape, like a leaf, and its total area is about 4,468 square kilometers, with a total mass of about 76.2 billion tons.

At the Leaf Space Station people use an advanced recycling purification system that allows water to be reused to grow space vegetables, fruits and rice, and there are small swimming pools and artificial rivers.

Thanks to β the translucent alloy glass, the leaf space station can filter out most of the infrared rays of the sun's radiation, effectively reducing the heat of the sunlight in the space station, so that the temperature in the space station is not too high.

In addition, due to the huge mass of the leaf space station, it cannot land on the surface of any planet or satellite, and can only inhabit the synchronous orbit of the attached stars, so it is also a leaf space station and a large space carrier. The fuel used by the large hydrogen-oxygen engines installed in the space station comes from the domestic wastewater of human beings in the space station, and a small part of the wastewater is filtered and enters the hydrogen-oxygen engine system for high-pressure decomposition, compressed into liquid hydrogen and liquid oxygen for separate storage and standby.

Most of the domestic garbage in the space station, including the solid dust filtered out of domestic sewage, can be reused, and the solid waste will basically be transformed into organic soil for space planting. A small portion of the non-renewable solid waste is compressed and sealed and transported to Mars by a small space garbage truck equipped with a one-way fuel engine, where it is discarded along with the solid waste.
