The dark moon is heavy and the sky is shrouded. Undercurrents surged in the night, as if earth-shaking disputes were brewing in the martial arts world. And the source of all this points to the hidden rumors in the rivers and lakes, Manluo Valley. Manluo Valley is the number one assassination organization in the Jing An Dynasty. No one knows where it is and who is in charge of it, but more than half of the changes and disputes in the world are closely related to it. His masters are like clouds, but they are hidden in the mountains and forests or in the city, and outsiders have no way of knowing even one or two. What outsiders know is that most of the masters in Manluo Valley are proficient in swordsmanship and hidden weapons, and their internal strength and lightness skills are not to mention, but other than that, they all have their own strengths. No matter which one is on the bright side, they are all characters that can make a name for themselves. However, to this day, no one in Manluo Valley has ever revealed their whereabouts or identity. Maybe it's because no one has seen the people in Manluo Valley, or maybe it's because those who have seen them are already dead. Just like the man in mysterious clothes who died in the dense forest that night.
