In the 19th year of the Republic of China, the war was in turmoil, and the Chinese cultural heritage was at stake. Huo Lanxi, a gold-touching captain who was carrying an ancestral corpse poison, went to Tingyuzhai in Hangzhou for a chance to survive. He met Shen Yunche, a reclusive Maoshan Celestial Master under the cover of an antique dealer. One is the taciturn and powerful treasure-protecting "Dragon", and the other is the poisonous and obsessed Shouwen "Yuan". Their first encounters were tentative and confrontational, and gradually a tacit understanding of life and death emerged in the secret fight between the secret agencies of the West Lake.
A fragment of a piece of paper leads to the secrets of a silk book from the Warring States Period, and the overseas plundering organization "Phantom" is watching. They bring their tomb robbing skills and the secrets of Maoshan, from the ancient tombs in southern Anhui to the beacon smoke of Luoyang, and then to the dangerous situation behind enemy lines on September 18, guarding the fire of cultural relics with their lives. The guard gradually disappears, and the love secretly arises. Love in troubled times has nothing to do with romance, only the determination of "I will protect your bottom line".
When the ancient jade of Longyuan was related to the luck of the dragon vein, they sacrificed their lives to seal and protect their home and country. The eternal freeze-frame of fingers clasped under an air raid, the old photos and diaries hidden in the ancestral home a hundred years later, this legend of two male protagonists guarding each other across centuries will eventually travel through time and shock people's hearts.
