I Have a Black Technology Sign-In System

Zhang Han is bound to a black technology sign-in system, and can obtain one black technology each time. At first, he acquired taste recording and playback technology, which allowed people to virtually "taste" all kinds of flavors in the world on the tip of their tongues. After the promotion, it not only changed the entire catering industry, but also brought good entrepreneurial opportunities to countless people. Subsequently, he obtained a number of super artificial intelligence technologies, which allow everyone to understand their own potential and find the life path that best suits them. Later, he acquired space mining technology. By mining special energy storage materials on asteroids, he created super batteries for large-scale solar energy collection in space. Each technology has greatly changed people's daily lives, making Zhang Han one of the 100 people who have influenced human history. This novel and its characters are purely fictitious.
