I Have a Sign-In System for Black Technology

Zhang Han binds himself to a black-tech sign-in System, which grants him one piece of cutting-edge technology each time he checks in.

At first, he obtains taste recording and playback technology, which lets people virtually “taste” every flavor in the world on the tips of their tongues. Once widely adopted, it transforms the entire food and beverage industry and creates excellent business opportunities for countless people.

Next, he obtains several advanced artificial intelligence technologies that help everyone understand their potential and find the life path best suited to them.

Later, he obtains space-mining technology. By mining special energy-storage materials from asteroids, he produces super batteries that can be used to collect solar energy on a massive scale in space.

Each new technology drastically changes people's daily lives, allowing Zhang Han to join the ranks of the hundred people who shaped human history.
