Baiyemen is the largest assassination sect in the world. There are only thirteen people in the sect, but all of them are frightening to the martial arts world. They are proficient in concealed weapons and poisons, and never leave anyone alive. Sect leader Gu Changyuan has been in charge of the sect for twenty years and has made countless enemies, but no one dares to offend him.
Until the imperial court and the six sects joined forces to encircle and suppress, Baiyemen was wiped out overnight.
Gu Changyuan fought with his life to protect his youngest son Gu Shiyan from escaping. Before he died, he stuffed a sheepskin scroll into his arms - that was the ultimate hidden weapon map of Bai Yemen's century-old effort, the complete map of the legendary "Tian Luo" that can kill gods and slay immortals.
The young man wandered around the world with his father's best friend, an old fisherman who was anonymous, hiding under a pseudonym and living a life of forbearance. He fished during the day and watched the stars at night, carving the drawings of hidden weapons into his bones. In the past ten years, he traveled all over the country, looking for thousand-year-old cold iron, poisonous spiders and pythons, and interviewing strange craftsmen from the Western Regions, and awakened the hidden weapons on the drawings from legends one by one.
Some of the enemies back then were granted the title of prince or prime minister, and some founded sects. They had long forgotten the night when their family was exterminated.
Gu Shiyan never forgot. With a box of hidden weapons and poison skills, he embarked on the road of revenge.
He wants those who are stained with the blood of Baiyemen to know that there is still one last name left on the hidden weapon spectrum.
