The protagonist Lin Yi, an ordinary delivery boy, has worked hard in the city for many years and devoted everything to his family. The blow of his wife's cheating and family breakdown made him return to his hometown - a small county with a backward economy but simple folk customs. At the lowest point in his life, a meteor hit him and activated the [Plane Foreign Trade System]. This system allows him to randomly connect to an alien plane every month and conduct inter-dimensional transactions with free pricing without interfering with any gaming behavior during the transaction process. The state secret service quickly intervened and established a joint venture company "Xingqiao Trading" with him. The protagonist is responsible for developing an alien dimension, and the country is responsible for the production, logistics and safety of Blue Star Terminal. With transactions one after another, the country has achieved leapfrog development in the fields of energy, materials, biology, medicine and other fields, and human civilization has entered the interstellar era. The ex-wife's family, on the other hand, has completely sunk in the ever-expanding gap and has become a footnote of the times.
