Mo Jingshen, a descendant of the Mohist family, accidentally discovered the bronze key to the Wuzu Temple and revealed the secret covenant between his father and the Honglian Sect. The bronze key points to the secret cabin of the Guiyan, and the Lotus Scroll records the war between the two factions against the forces of the Black Ship. The North and South Hongmen are divided, and the leader of the South Hongmen colludes with foreign enemies. Mo Jingshen brings the Four King Kong to consolidate the forces with the seven-petal lotus flag. From San Francisco's Chinatown to Guangzhou's Honghua Pavilion, they cracked the poison of the candle dragon, practiced the belief of "returning the wild goose and angelica" amidst the light and shadow of swords, and rebuilt the order of Hongmen in the blood and fire.
