In the "Fog River City" where the fog is thick all year round and the two rivers meet, the power structure is undercurrent. On the surface, the Jiang family, headed by "Lanyue Fang", controls half of the city's water transportation, and the family leader, Mr. Jiang, has a high prestige; secretly, the "Jiaolong Gang" entrenched in the east of the city colludes with the "salt owl" forces in the west of the city to monopolize private salt, act ruthlessly, and have constant friction with the Jiang family.
Purpose: For the sake of family and country
