Gu Xingzhou, an introverted college student who had just graduated, was worrying about a pile of resumes that were sinking after he submitted them. In the old courtyard of his urban village, there was a "clang" and a dark door of unknown origin fell down.
This door, with its weird temper, can randomly send him to a certain corner of ancient times. Maybe one second I was listening to a book in Wazi, a prosperous place in the Song Dynasty, and the next second I was squatting beside a dye vat in a small village in the Tang Dynasty watching people mix colors. The door is a "space jumping practice device" eliminated by an advanced alien civilization. Its performance is unstable and depends entirely on randomness.
Gu Xingzhou never thought about becoming king and hegemony, he just wanted to use this door to solve the immediate existential crisis. He discovered that not only was it illegal to bring back the antiques directly, but the energy of the door also did not allow it. But he can bring back "ideas" - those lost craftsmanship, exquisite patterns, unique formulas and warm human stories.
Thus, a unique business plan was born.
