In the late Hongwu years of the early Ming Dynasty, secret struggles for imperial power were intertwined with turmoil in the world. Guo Jing, a young man from the frontier army, was involved in a shocking whirlpool because of a compass token engraved with mysterious sea patterns. This token was related to the "Firearm Spectrum" that could reverse the fate of the country, attracting factory guards, feudal lords, and evil factions to compete for it.
On the dangerous journey of being ordered to deliver the token to Wudang, Guo Jing met Huang Rong, the daughter of the Southeast Sea Owl. This strange woman who is proficient in firearms and navigation combines the loyalty and bravery of a frontier boy with the wisdom of a daughter of the ocean. From testing each other to trusting each other in life and death, the two fought wits against evil in a deserted village and shop, broke out in the dark night amid the turmoil of the city, and jointly faced the tangled web of people who were chasing people in the East Factory.
The work is based on classic martial arts and has historical suspense as its wings. Through the growth process of the two protagonists, it shows a magnificent picture that blends the wars of the frontier and the waves of the sea. While inheriting the spirit of chivalry, it innovatively integrates elements of firearm technology and navigation adventure. There is not only the interlocking mystery of the tokens, but also the touching journey of Jing Rong and Jing Rong from the collision of personalities to the connection of fate.
