Gao Yuan, a senior high school student, accidentally traveled to the Yan Dynasty and became a useless scholar with the same name. Just when he thought he was going to be finished, he was surprised to find that the imperial examination in this world actually tests mathematics, physics and chemistry! What's even more outrageous is that the smartphone he carries is connected to a modern network. Therefore, Gao Yuan began his ancient tricks: using calculus to crush corrupt scholars, using chemical experiments to improve agricultural tools, and using physical laws to design water conservancy projects. The top imperial examination in the world was scolded as "the questions are too easy", the most arrogant talent in the dynasty was criticized to the point of being autistic, and the most beautiful princess in the dynasty fell in love with him at first sight. Just when he thought he could cheat to the end, a mysterious organization focused on his identity as a time traveler - they called him a sacrifice for "the right girl". Only then did Gao Yuan discover that his time travel was a trap carefully planned by someone, and that he was just a pawn in this thousand-year conspiracy. But the question is, when a modern academic master meets an ancient villain, who will be the final winner?
