Feng Wujiu, a doctor of chemical engineering, transformed into Feng Qing, an unlucky little official who was demoted to the Military Superintendent's Mansion and was in charge of the alchemy room for offending the powerful. Faced with the mess left by the original owner, the rejection of his colleagues, and the upcoming troubled times in history, he decided not to tolerate it anymore.
Using the readily available sulfur, saltpeter and charcoal in the alchemy room, he "accidentally" restored black gunpowder. A thunderous explosion not only shook the imperial city, but also brought him into the sight of the prince and An Lushan factions. He originally wanted to only offer the formula in exchange for stability, but he was forced to get involved in the most dangerous battle for the crown prince.
He used gunpowder for mining, but the secret recipe was coveted by the powerful; he improved a simple artillery for border city defense, but it attracted the assassination of Tibetan spies. From modifying crossbows to establishing the first professional firearms battalion, from passive self-protection to active deployment, Feng Qing gradually discovered that what he had ignited was not only gunpowder, but also the fuse that completely rewritten the fate of the empire and China's technological tree. At the turning point of the Tang Dynasty turning from prosperity to decline, how should a small official with the power of "Sky Thunder" survive in the furnace of power, and how should he face the unknown storm brought about by the early arrival of technology?
