When modern chemistry PhD Lin Feng’s laboratory exploded, he woke up as a puppet emperor of the Tang Dynasty. He had the empress dowager above him, powerful ministers in court, and a national preceptor in the palace. Everyone was waiting to see how he would die.
Then, on a memorial about alchemy, he wrote a single line: “Mercury vapor is toxic. A gas mask is recommended.”
From then on, the science student’s overwhelming advantage began. He used saltpeter to make ice and humiliated the rain-praying ceremony, wielded a cement formula against the entire court, introduced patent law and drove the great clans up the wall, then made gunpowder and firearms that left the Turkic cavalry with nowhere to run.
From a little emperor everyone could manipulate to the “Emperor of Science” who made an entire era fall silent, he used knowledge to show everyone that in this world, science is the greatest cheat code.
