What did Star Trek write?

The story takes place in the future world. The population on the earth is growing rapidly, and the demand of human beings has far exceeded the supply of land. At this time, science and technology have also made great strides. Just visiting replaced the spaceship and undertook the task of transporting immigrants to other planets.

Rod Volcker, a high school student, chose a course called "Advanced Survival". The final exam of this course is to send participants to a strange planet with hostile creatures for 2 ~ 10 days. During this period, participants have to rely on various devices they carry to survive, and they can also team up with others, but they can't get any help from the earth. In the end, whoever can survive will pass the exam.

However, when these participants were sent to a strange planet, they happened to encounter a supernova explosion, and time and space were split, and the time tunnel used to remember the participants failed.

After living there for 10 days, Rod Volcker found no signs of remembering them, and he began to realize that he was trapped on this desolate planet. Here, the survivors of the exam slowly gather together, unite as one and face difficulties together. Rod Volcker became their leader and a stable group of about 75 people was formed.

These well-educated young people followed in the footsteps of their ancestors and established a whole set of social systems. They built castles, elected governments, made laws, developed farmland, domesticated animals, bred offspring, and made preliminary development in industrial fields such as textiles and smelting ... A few years later, the earth contacted them again and recalled most people to the earth. Rod Volcker became the only one who insisted on staying to protect the created civilization. His sister and his survival teacher finally changed his mind and persuaded him to return to earth.

At the end of the story, Rod Volcker became an immigrant development manager, and he was going to lead his team to another planet.
