Through Xiaoqiao's description, everyone finally clarified the whole story of the events.
It turned out that Xiaoqiao was not an only child in her family; she originally had an older brother.
However, during a family trip, as they were crossing a glass walkway, an earthquake occurred. Although the glass walkway did not collapse, the panic caused by the earthquake completely scattered their family.
Xiaoqiao was lucky enough to be quickly found by her parents, but her brother was completely lost from then on.
Even after more than a decade of searching by her family, there had been no success.
This time, by participating in the starship migration, Xiaoqiao wanted not only to carve out her own destiny but, more importantly, to search for her lost relative.
