In the evening, at the source of Sun and Moon Stream, the soft sunset, and the gorgeous clouds seem to lie across the mountains not far away, and at the foot of the mountain are a cluster of villages leaning against the mountains and waters.

The sunset and mist in the sky swirl around each other, and the surrounding scenery gradually emerges from a hazy area.

Looking at the foot of the quiet mountain, the lush trees on the mountain seemed to be covered with a halo. A clear stream winds down the mountain, and the stream water slowly slapped on the rocks. The smooth pebbles in the stream can be clearly seen, and the mountain clouds in the sunset are also reflected in it. There is also a quaint small stone bridge on the stream, and everything looks so simple.

Yuan Shichen walked across the small stone bridge and arrived at the front of the village. The extremely familiar building quickly rushed into his eyes. His mother was already waiting at the door with a sweet smile.

Although Harashi-chan once left home to live alone in high school, he was relatively short and the distance was close.

However, the six months he spent studying at Tsinghua University deeply felt the longing for his relatives far away from home.

So, when he stepped into the house and saw his parents, his heart felt indescribable warmth.

Under the warm light, a table of food carefully prepared by my mother was placed. During the dinner, the parents who were not good at speaking were just smiling. Listening to Yuan Shichen's narrative of the little things and fresh experiences that happened in school in the past six months, there were bursts of joyful laughter floating in the room from time to time.

............

As the night became deeper, Yuan Shichen searched through the bookcase in his room to find the strange ore that had been properly stored before.

Yuan Shichen understood that he was not able to uncover the mystery of this ore.

But he is always working hard to improve his abilities and cognitive level, and I believe that in the future, there will be a day when the moon is cleared and the truth will be revealed.

Next semester, he can choose Dean Li's scientific research project as his graduation thesis, which means he will have the opportunity to use the technical equipment of the school's scientific research laboratory to analyze and research this strange ore.

Thinking of this, he was always calm and excited.

So Yuan Shichen carefully packed the ore and put it in the suitcase that was about to be taken back to school.

............

During this time at home, Yuan Shichen basically stayed with his parents and worked hard in the green vegetable base at home every day. He knew in his heart that as he went further and further, he would spend less and less time with his parents in the future, so he cherished every minute of being with his family.

During this period, Yuan Shichen also attended several high school classmates' reunions and met Fang Xiaoyu and Wang Sanke who had been missing for a long time. Fang Xiaoyu met a female classmate at school, and then the relationship between them quickly heated up and became an extremely flirtatious couple. Moreover, during this winter vacation, Fang Xiaoyu also invited her to visit Hanhai City. Yuan Shichen had also met several times and was a very gentle and sweet girl. Wang Sanke has traveled all over the natural scenery of northwest China in the past six months. Now, people have become much more prosperous and rough. As expected, it has verified that reading thousands of books is not as good as traveling thousands of miles.

Soon, the happy holiday and the Spring Festival passed, and Yuan Shichen embarked on his journey back to school.

Because Chen Shuqin went out for the Spring Festival with her family during the winter vacation, and then returned to school directly, Yuan Shichen returned to Beijing alone this time.

............

The new semester soon began step by step, and teachers and students of the School of Astronomy are discussing the matter about Yuan Shichen.

A freshman passed all the original four-year study course assessments last semester and received the corresponding credits. This semester, he would start researching thesis with the dean in advance.

In the dormitory, Zhang Xiaoming was shouting: "Qian Chen, it's really amazing. We were all top students in school before. Now, when we compare with you, we are like poor students, and we feel ashamed of ourselves!"

"If you don't look at how hardworking the other person is, it's not like you are immersed in a gentle country every day." Yang Yang joked about Zhang Xiaoming and Lu Qiufang.

The young master Chao sat on the chair and said nothing, but turned his head and gave Yuan Shichen a thumbs up.

"It's nothing, it's just that everyone is interested in different aspects..." Just as Yuan Shichen explained routinely, a pillow flew towards him.

"Let you show off~ invite me to dinner tonight." Everyone started to joking and fighting.

Dean Li is a doctoral supervisor at the School of Astronomy and rarely teaches undergraduate thesis. However, Dean Li's laboratory happened to have a cross-disciplinary project on meteorites and astrochemistry this year, and students with bachelor's degree are suitable for teaching as research topics for graduation thesis.

Therefore, this project naturally fell on Yuan Shichen.

Yuan Shichen's main task is to analyze and detect meteorites collected from all over the world at the first time, and then study the main information such as the main components, evolution, and formation of the solar system nebula.

Yuan Shichen had already dabbled in a lot of books about meteorites last year, so he was very familiar with them.

Meteorites are unburned stone, iron or stone-iron mixed substances that are separated from their original orbits from the Earth and are quickly scattered onto the surface of Earth or other planets.

Meteorites have different shapes. More than 40,000 meteorite samples have been collected around the world. They can be roughly divided into three categories: stone meteorites, iron meteorites, and stone iron meteorites.

The largest meteorite found in the world is from China, weighing 1,770 kilograms, and the largest meteorite is the Goba meteorite in Namibia, weighing about 60 tons.

Most of the meteorites on Earth come from the asteroid belt between Mars and Jupiter, and a small part come from the moon and Mars.

Astronomical scientists have discovered over the years that there is an asteroid belt between the planets in the solar system, Mars and Jupiter orbits. This is the hometown of meteorites. These asteroids are orbiting and constantly colliding, and sometimes they will be knocked out of orbit and run towards the earth.

Our earth receives 50,000 tons of such "gifts" every day.

Of course, most meteorites burned out at a height of 10 to 40 miles from the ground, and it is difficult to find even if they fall on the ground.

Since meteorites are not protected during the process when they operate in the universe, they are directly affected by radiation and catastrophes from various cosmic rays. Therefore, meteorites record a lot of reliable and valuable information. They have important scientific research value in astronomy, celestial evolution, geochemistry, and the research on the origin of life.
