What's wrong with this accident? The USSA spent a day conducting an investigation, and finally replied to the 10 people: Hello, the manned warehouse was originally going to carry the material, but the mission manager received the wrong information, so it caused the accident. USSA is sorry and will make amends immediately.

Money is a trivial matter, Xie Heng thought, if it weren't for Admiral Zhou's use of zero force to slow down, whether it was the space station in the sky or the people on the ground, it would be impossible to escape the fracture caused by the damage to the cloud tower running at extremely high speed.

Now, he and Zhou Wujun are staying in District 13, where they learn that District 13 will be abandoned and converted into civilian facilities for people to play and stay. Xie Heng looked at the yellow sand outside the window, worried about whether this place was suitable for people to play, the image in his pupils did not have a trace of green, only the lifeless wind and sand suppressed by technology.

When mankind entered the 22nd century, the problem of wind and sand has been solved. They hid black rivers underground and sprinkled a special type of sand in heavily weathered areas to mitigate dust storms and air pollution. Although it has been continuously laid out by human beings, it has taken nearly 20 years.

Xie Heng could see the dry and cracked riverbed in the distance, the dry cracks, and he was longing for his children to nature, but he didn't respond for a long time.

Instead of drinking river water, humans mainly squeezed ice from the poles, supplemented by purifying sewage and seawater, to meet the daily water consumption of 5 billion people. A small number of wealthy people have access to the thousand-year-old ice water of the highlands, which is also drunk by important people of the state and guests.

"Humans know how to apply it rationally because they have zero element crystals." Xie Heng said, taking out an eyeball-sized polygonal crystal from his pocket. According to its true nature, it shouldn't actually be called a crystal, but Xie Heng doesn't care.

He held it in front of his eyes, and the light from the outside did not refract through it. Xie Heng was too obsessed with this piece of Zero Element Crystal, which was less than a gram, even if he held it in his hand without any temperature, he would use his strength to sense the pain. Zero Crystal has no temperature, to be precise, he can't sense anything other than body temperature, but he also understands that this substance is contrary to thermodynamics.

The transparent yellowish zero-element crystal can allow visible light to pass through, and electromagnetic waves can also pass through, but it does not allow heat to pass through, which is a difficult problem in many historical studies on zero-element crystals. Xie Heng hoped to find a starting point for his research, but a month failed to make him discover anything.

There was a knock on the door suddenly, and Xie Heng turned around and opened the door. He glanced at the retro clock on the wall and saw that it was 10:24 a.m.

He opened the door and heard a question: "What is today's date?" ”

"October 17th." Xie Heng completely opened the door and saw Zhou Wujun standing in front of him, he said respectfully, "Please come in." ”

"Xie Heng, I came to you for something very important, you should know ......" Zhou Wujun quickly summoned a class of zero seals, and then released metal particles to fill the room. He was sure that someone was spying on them.

Zhou Wujun closed the door lightly and said with a heavy face: "You know about last month's attack. In fact, the pilot is not a human, he is a high-precision pseudo-human, and the Thunder-20 fighter is also a copy, and its production process is comparable to that of an old mechanic in a national military factory. ”

Xie Heng asked, "You mean someone leaked the drawings?" ”

"No, do you remember what I said about 'them' the other day?"

"Someone who is against you. However, the ALC has been disbanded, is it necessary for them to continue the pursuit? ”

"I don't know, but I sent someone to investigate this matter secretly, but there are no clues for so long. They sent me a threatening letter back in June, in which they swore that if you dare to disband the ALC, we will dare to attack you. Zhou Wujun lowered his head and said.

"It seems that the forces behind the scenes are still too rampant, and we can ask the National Bureau of Investigation to conduct a thorough investigation."

"It doesn't make sense, did you find the legal name of Zone D? It is a science and technology research institute under my name, and the relevant personnel of the state have not investigated. ”

Xie Heng felt a lot of pressure, he gasped and looked out the window, the reflection of the huge cloud tower spread on the riverbed in the distance. It stretched farther away, blocking out the sun that had just risen there. He was uncertain of his safety, and he was even more afraid of a rocket flying from the sky, the dull air pouring into his lungs, giving him the oxygen he hoped for.

He calmly asked, "What should we do?" Find them and arrest them? ”

"They will definitely show up, and they will definitely explain the reason for the attack on us." Zhou Wujun muttered.

December 24, 2230, Explorer Fleet - USS Century.

In the evening, the caretakers decorate their rooms and tomorrow's Christmas conference room with a glittering Christmas tree. They'll get ready for Christmas Eve tonight, and then they'll be in the lounge area reading greeting cards from friends and family and 27 years of tear-jerking video letters.

Su Mo was preparing in her room, and she changed into a dress that Bai Fengyi liked, which was the white dress she wore when the two first met. But when she stood in front of the mirror and saw her delicate face, she seemed not so happy. Her sadness cut across her face, and she didn't move.

"Important Notice!" The AI's voice suddenly sounded, causing Su Mo to suddenly turn around to check, and she asked the AI to announce the notification, "Caretaker Su Mo, in view of your relationship with Bai Fengyi, the system has decided to let you check the letter of the explorer Bai Fengyi." ”

"Oh, thank you." Su Mo didn't show that she was very happy, but her brain was like a volcanic eruption, constantly generating substances that made her happy. She was systematically recognized, although Bai Fengyi was never sure.

After taking care of everything, Su Mo prepared to close the door and leave. As she had just stepped out of one foot, she looked at her slender right hand, which was perfect for the bracelet that Bai Fengyi had given her. She turned around and found it, then put it on.

At that moment, a voice suddenly sounded:

"Time."

"Who is it?" Su Mo raised her head and said in surprise, it was a magnetic, low female voice, she scanned the surroundings and didn't find anything to talk to, so she could only shake her head and comfort herself: "Just take it as an auditory hallucination." ”

At 8 p.m., all the caretakers arrived in the break room, where they exchanged the cards and gifts they had prepared, and sent each other their sincere wishes, and then waited for the robot Ultra to bring them the letters they were looking forward to.

Christmas is to commemorate the birth of Jesus, and compared to Westerners, it is a festival that represents the past year, and in Eastern countries, the Spring Festival is a day of reunion, so only Miles and others are very excited. In the Peace Tie program, in order to fulfill the wishes of the caretakers for the New Year, the Spring Festival in the first half of the year and Christmas in the second half of the year are specified, and both Westerners and Easterners can spend any holiday.

Sumo was bathed in the festive atmosphere, and she could see ambiguous people snuggling up to each other, sitting with Jerry and Tina, and Miles and Hurley were very sweet. In addition, Wang Nan was given a rose in the summer, and Feng Gao also attracted everyone's knowledge. If you want to count the lonely people, except for herself, it is He Chuan.

Half an hour later, Ott led a robotic elk into the rest area. He smiled and said, "I'm going to make the cards and letters paper, and if you don't mind, it's going to be more fun." Of course I never opened it. ”

He was dressed in Santa Claus's clothes, but it seemed a little too early. He handed the greeting card and letter to the caretaker, but when he faced Su Mo, he said sadly: "Poor Su Mo, the system has not received any greeting cards or letters about you. He suddenly raised the corners of his mouth, "But your boyfriend Bai Fengyi is willing to share him with you." ”

Ott tried to make Su Mo happy with funny words, but the other party just said: "Thank you." ”

"You should be happy." Ott smiled and handed her the letter, and asked, "Will you send the message again tonight?" ”

Almost everyone sympathized with Su Mo and sympathized with her going to send a message to Bai Fengyi, who had no news, every night. Only He Chuan couldn't say anything, so they all jokingly called him a cold-faced ghost, but they wouldn't say it in front of others.

"Yes, I still want to send it." Su Mo nodded solemnly.

Winona knew that her judgment was about to collapse, so she used many theories to show that the Savior was not lost. She told all the caretakers: they are still on their mission, and you can send them a heartwarming message.
