In the 20th year of Qianlong's reign, the imperial kiln in Jingdezhen was ordered to produce a set of "all nations come to court" enamel porcelain to celebrate the birthday of the King of England. However, what few people know is that under the nine layers of glaze, there is a top-secret map related to the southeastern coastal defense. Thin-bodied porcelain has been tempered by fire and has become a battlefield for all parties.
Before the fire in the kiln was extinguished, the British East India Company's commercial spies had sneaked into the porcelain capital and bribed the craftsmen with huge sums of money; the Portuguese Jesuit missionaries were working on both sides, using the name of surveying and mapping to explore the truth; the guards at the imperial court's stick-stick department and the spies of the Tiandihui were fighting life and death in the dark alleys of the rough houses. Tang Nianqing, the inspector of pottery, has a dual mission - not only to ensure that this "porcelain spy ship" can go abroad perfectly, but also to protect the secrets of the country deep inside the body.
When the porcelain-carrying "Canghai" sailed south, the secret war in the kiln fire spread to thousands of miles. Merchant ships in the Age of Discovery became mobile spy nests, and every glaze crack could cause a loud noise. The glorious journey of porcelain across the ocean eventually evolved into a silent war that determined the fate of the country.
