In the highly hierarchical Dayu Dynasty, merchants were the last of the four people. Liu Chenfeng, with his "humble" identity as the son of a Jianghuai merchant, won the title of martial arts champion despite many obstacles, shocking both the government and the public. This move attracted sharp sarcasm from Ye Chaoyu, the daughter of Yanbei's famous general: "The smell of copper covers your bones!" The fate of two souls who are worlds apart collided for the first time because of the firearms conspiracy of the Rakshasa Mission.
War smoke suddenly rises in the northern border, and the four ambitious countries are eyeing them: the Rakshasa cavalry carries the "Thunderbolt Gun" to split the territory, the southern frog poisonous poison sneaks and wreaks havoc in the market, the Japanese ninjas are plotting in the shadows, and the Xirong cavalry is waiting for an opportunity to plunder the border. When the country is in crisis, the prejudices of the court, the grievances of the world, the hatred of the country and the family have all turned into a sweeping disaster.
Liu Chenfeng has repeatedly accomplished extraordinary feats by relying on his businessman's cunning, extraordinary martial arts, and keen knowledge of weapons and ingenuity. He defeated the enemy with the wisdom of the market, like salt corroding an ice city and fire burning an iron ship. He proved in the light of swords and blood that business roads connected the world and could also be turned into sharp blades to protect mountains and rivers. Ye Chaoyu bears the honor of being a general and a painful family feud. He is unparalleled in bravery on the battlefield, but Yan Bei's iron blood cannot conceal his impulsiveness and fiery kindness. When the conspiracy broke out, she shot a suspicious arrow at Liu Chenfeng, and the former "brazen bastard" actually became an unspeakable pain in her heart. There are many misunderstandings, and life and death are at stake. From cutting one's wrists to use warm blood to relieve the "Frost Blade" poison, to breaking one's hair and tying arrows to defend the isolated city on top of the ice city, two proud hearts are torturing, colliding, and getting closer in the furnace of blood and fire.
The Yanbang waterway network, the Tangmen Thunderbolt Fire, the Iron Spear and Horse Resistance Formation... Jianghu forces were involved in the Four Kingdoms War.
