In the bustling No. 56 Siping Road, Shanghai, a sudden fire devoured everything. Firefighter He Feng died heroically in the sea of fire to save a little girl, but was saved from the brink of death by the mysterious scientist Yue Yang - he was injected with the "purple element" and became a "fire demon" with the power of fire. He Feng was reborn after 90% of his body was burned. His skin burned like a flame. When he lost control of his emotions, he could spit out flames and even condense a fire blade out of thin air. However, the appearance of Yue Yang reveals a deeper conspiracy: "There is a hidden black hand behind this fire, and the truth behind your death is far more than death in the line of duty." As the protagonist gradually controls the "Fire Spirit Body" form (skin turns golden, and the flames move according to his heart), he must wear a skull mask to hide his identity, wandering between revenge and redemption. When special training in the laboratory reveals the truth about the power of fire, He Feng will embark on a journey to destroy the black hand of fire - will he turn into a karmic fire for revenge, or become a flame spirit to protect the world?
