In the early years of the Republic of China, there was heavy snowfall in Northern Shandong. Young Wang Wu huddled in the corner of the mountain temple, carrying an ancestral butcher knife. A military disaster reduced him to a rootless duckweed in troubled times.
A fateful encounter brought him to Beiming Mountain Taoist Temple, where he met Taoist Zhang who was like his teacher and father, Uncle Wang who was both strict and compassionate, and his senior sister Liu Lili with eyes as clear as springs. He thought he had found a paradise in troubled times, practicing calligraphy, practicing Qi, and watching plum blossoms bloom and fall in front of the court.
However, the claws of the Red Lotus Sect tore all of this into pieces. In the light of the sky, the master burned up all his true energy, and the junior sister died. In order to take revenge, he resolutely embarked on a desperate road, dedicated his heart and blood to the "Nine Nether Ghost Lotus" from the netherworld, transformed into a ghost baby, and was reborn in the world.
Ten years later, the evil sword was unsheathed! He is no longer the ignorant young man, but the "Shadow King Five" who possesses the power of a ghost leader and makes cults fearful. Fortunately, his sword was not just for killing. He met the eminent monk Mingchen in an ancient desert temple and planted the idea of compassion in his heart. He sneaked into the Longtan Tiger's Den alone, only to find that his lost love had become a "container" for the evil cult to descend on the ghost king...
On one side is a warm and carefree and comfortable life, on the other side is a life of near-death and numerous crises. When the blood lotus blooms again and one hundred thousand souls are about to be sacrificed, where will the evil sword in his hand point?
This is the awakening of a sinister sword and the redemption of a human heart. In the troubled times of the Republic of China where demons are rampant and people's hearts are full of ghosts, watch a young man holding a evil sword, slaying evil spirits, asking his true heart, and composing a passionate legend of his own.
