He was once the "Star Merchant Emperor" who stood at the top of the commercial war in all realms, but when he reached the peak, he was betrayed by his relatives, and his soul perished in the endless galaxy. When he opened his eyes again, he was reborn in the earth city at the age of twenty-three - the night of desolation when he had just been kicked out of his family and his fiancée had broken off the engagement. In this life, his left hand holds the secret code of business in all realms accumulated in his previous life, and his right hand awakens the "World Star Gate" that can travel through all heavens and realms. Starting from setting up a street stall to sell improved elixirs, to founding the "Star Group" that sweeps the world; from urban business wars to resource monopoly in the fairy world, from science and technology plunder in the science fiction plane to survival transactions in the apocalyptic wasteland... He wants to build the largest business empire in all the worlds, and let the flag of the "Star Business Alliance" be planted in every dimension. And those who have betrayed him will witness with their own eyes how he uses business methods to become emperor and return to the top of the world!
