One day, two years later, Lucy and her parents were enjoying breakfast at home when a string of cheerful voices came into the house from the door.

"Lucy, look what this is."

Lucy looked up and saw Denise rushing in with a card in her hand.

Lucy took the card, held it up in front of her eyes and looked at it, and suddenly her eyes lit up, and she jumped up from her chair with joy.

"What are you so happy about?" Mom Kate couldn't help but ask when she saw Lucy's excited look.

"Lo and behold, I've been accepted to the Martian Space Military Academy!" With that, Lucy handed the card to Kate.

When Owen heard this, he also put down his work and hurriedly stepped forward.

Kate took the card and looked at it carefully. It is a metal card with a faint brown vein on its surface that symbolizes the original colors of Mars hundreds of years ago. At that time, human beings had not yet set foot on the land of Mars, and both the sky and the land were dominated by light brown.

Most strikingly, there is a conspicuous line of text engraved on the surface of the card: Space Cadet Identification Credentials.

Kate noticed that there was a pinky-sized sensing area in the corner of the card, so she rubbed it with her finger. Suddenly, a light brown stereoscopic image was launched from the card sensing area, and a female *** wearing a space military uniform appeared in it.

The female instructor has clear eyebrows and beautiful eyes, and her posture is heroic. She opened her mouth and said, "I am Tian Huimei, the provost of the Space Military Academy. First of all, congratulations to you - the new cadets of the Space Military Academy. When you receive this Space Cadet credential, you are officially a part of us. On behalf of all the instructors of the Space Military Academy, I wish you to experience training, harvest and growth in this collective, and become the proud pillar of the Space Force. ”

After the female instructor finished speaking, the subtitle "Admission Instructions for New Cadets of the Space Military Academy" appeared in the video. Lucy clicked on the subtitles, and then the video showed information including a brief introduction to the Space Military Academy, a guide to the registration of new cadets, and so on.

According to the introduction, this space military academy on Mars has a history of 300 years, dating back to the time of the great development of Mars. The full name of the school is Alba Space Military Academy, which is named after the fact that it was founded on the Alba crater on Mars. This space military academy is affiliated with the Mars Federation Space Force, which has trained a large number of space force elites for the latter. More than eighty percent of the high-ranking officers and generals of the Mars Federation Space Force graduated from the school. Many of the other Federal Space Forces have also studied here. As a result, the Alba Space Military Academy became the top space military academy in the Federations of the solar system...

After reading this information, Lucy's family was very happy. Owen and Kate know their daughter well, knowing that she has been following her grandfather's example since she was a child, hoping to become a Space Force soldier. Now she finally got her wish, and they were all happy for her. That night, they also invited relatives and friends to their home to have a lively time.

In the dead of night, Lucy lay in bed tossing and turning, unable to calm down for a long time. She has many beautiful hopes for the future, but she also has a trace of indescribable and unexplained worries. She thought of her grandfather again, and she also went to the interstellar communication center to "meet" with his grandfather last month. At that time, I heard my grandfather say that I was about to reach my destination. Isn't he already there by this time? Lucy decides to go to the Interstellar Communication Center the next day to meet her grandfather again and tell him the news that she has been admitted to the Space Military Academy. Thinking about it, Lucy fell asleep.

Early the next morning, Lucy, accompanied by her parents, took the Sky Express to the Interstellar Communication Center. The building is shaped like a giant globe, with a needle-like pillar with a thick lower end and a thin upper end passing through the center of the "globe" and reaching into the sky.

Lucy's family walked into the lobby on the first floor and pressed their finger on the front desk kiosk, which displayed a column of information on the terminal screen: Reservation Communication Room 705, one of the 1,000 communication rooms in this interstellar communication center.

At this time, outside the 705 communication room, there were still several people waiting to enter. Lucy waited in line behind them for more than an hour, and finally it was her turn. So Lucy walked into the communication room full of joy...
