It is probably about a planet that is independent of the four-dimensional world. It is very lonely in that dimension. It is called Lantian Star. The planet number is paradox24822. Then Yuanxing is a descendant of a founder (who created Lantian Star). Yuhan is a person who discovered this planet from the earth and raised him. Finally, he met Yuanxing and studied with him about things like curvature-driven spaceships, jumps and force fields. Siyi is Yuhan's childhood friend. Then after growing up, he was invited to Lantian Star to help solve the problem of transition and resources, involving micro-fusion, the development and utilization of heavy metals such as uranium. Because there is a theory circulating on Lantian Star recently that the loneliness of Lantian Star is actually an illusion. If the hidden civilization is willing to attack, Lantian Star will soon lead to a head-on conflict. Therefore, the appearance of Xu Siyi can be regarded as a turning point in the development of Lantian Star. However, Siyi and Yuhan had conflicts that have not been resolved. Only then did we have the scene at the beginning of the short story where Lin Yuhan went to borrow a curvature-driven spacecraft to travel after Xu Siyi arrived (perhaps to find out whether the rumors were true or not)
