Sensing Lucy's strangeness, Li Jun asked with concern, "What's wrong?" ”

"Oh, nothing." Lucy said that she didn't want to talk about the matter between her and Kevin in front of others. "I'm a little tired and I want to go back and rest."

"Alright then, I'll send you back." Li Jun sent Lucy back to the room.

Before leaving, Li Jun and Lucy exchanged contact information and other information. In order to prevent any unexpected troubles, Li Jun specially told Lucy: "Call me as soon as there is anything." ”

Lucy nodded, "Okay." ”

When she returned to her room, Lucy lay on the bed and couldn't sleep. She remembered the time she had asked Kevin about his family and family, only to be vague or sidelined by him. She didn't know why Kevin kept hiding his identity from her, whether it was because he deliberately kept a low profile, or if he didn't see her as a friend at all.

Lucy remembered the many times she spent with Kevin. In her opinion, he is so sunny and cheerful, and there is always a warm and warm smile on his face. It doesn't look like it's pretended, and it won't last long.

Thinking of this, Lucy still chooses to believe Kevin's sincerity, believing that he must have his reasons for doing so. She decided to put this question aside for the time being, since Kevin didn't want to reveal his identity, then she also respected his idea and shouldn't get to the bottom of it. Lucy's heart was much lighter when she made this decision.

Lucy looked at the time, and before she knew it, the spacecraft was about to arrive on Mars. She looked out the window, and Mars was like a behemoth in front of her. The large mountains and gorges on the surface of the earth, as well as the man-dug Grand Canal, are visible to the naked eye. After hundreds of years of migration, Mars has been transformed from a barren planet into a thriving second Earth.

As the spacecraft skimmed through the orbits of the Martian moons, Lucy was attracted to two of them. One moon is Titan, which is rich in hydrocarbons and various Greek elements. The former is an important energy source as the regular power of the spacecraft, and the latter is used as an important material for the construction of the spacecraft.

Lucy had seen the news before that Interstellar Mining Group had obtained the exclusive mining rights of Titan with the authorization of the Martian federal government and built a large-scale mineral mining base on this planet. But in the mining process, due to the company's use of forceful means to evict the indigenous people, but also to infringe on the interests of the early developers of Titanstar. As a result, the people's grievances on the planet are boiling, and conflicts between the parties are continuous.

Another satellite that Lucy has an eye on is Space City 2, which is located in a geosynchronous orbit around Mars. Space City 2 is quite different from Space City 1. It is shaped like a planet, a standard sphere with a diameter of 100 kilometers. The outer surface of the sphere is smooth as a mirror, covered with a solar absorbing membrane, which emits a faint yellow halo when exposed to sunlight. The inner city of Space City II is located on the inner surface of the sphere, and the spacecraft can enter and exit the city from the six entrances and exits of the sphere.

Lucy remembers following her parents to Space City Two once. In her impression, Space City 2 has both an urban area full of high-rise buildings, as well as mountains, lakes, rivers and forests. Standing anywhere in the city and looking upwards, you can see another city upside down in the sky, like a castle in the sky.

There is also a small artificial "sun" in the center of the sphere of Space City 2, and when the time of Space City is "daytime", the "sun" appears on time and illuminates the entire city. At night, the sun goes out and disappears, and the city falls into darkness. After all, human beings are still accustomed to living a sunny day and a life that alternates between day and night.

Lucy felt a slight tremor of the ship at this point. This is due to the fact that the spacecraft braked and turned on the guards, preparing for landing on Mars.
