On the night of the Zhongyuan Dynasty, hundreds of ghosts walked at night. In order to save the children, young Lin Xiaohuo was forced to awaken the ancient glutton sealed in his body. The moment the scarlet demon power tore through the night, he became a monster of "human and demon symbiosis" in the eyes of the world, and was chained by the Demon Suppressor.
Mo Chen, who was supposed to be a close friend who shared life and death, resolutely betrayed him because of the truth about his family's sacrifice and the dark list of "necessary sacrifices" made by the Demon Suppressor, vowing to overthrow this hypocritical order and establish a new world of absolute justice.
On the one hand, there is a heart-gnawing curse, and every time he uses his power, he is one step closer to demonization; on the other hand, close friends turn against each other, the world collapses, and when spiritual energy is revived, vicious monsters run rampant, and the Shadow Pavilion wants to cut off the dragon's veins and rebuild a new world.
Su Xiaorou, the descendant of Yaowang Valley, breaks the precepts for love and protects the troubled times with medical knowledge; the atoning master Lao Chen hides a shocking secret and uses his life to practice redemption.
From the conceptual break at Naihe Bridge to the showdown between the three realms in the Three Gorges, Lin Xiaohuo walked forward on the thorns - he did not want to destroy the demon, nor did he succumb to the demon. He just wanted to find a third way: people and demons would no longer kill each other, so that no life should be sacrificed easily.
Bonds and responsibilities collide, order and humanity clash. When the glutton's fangs are aimed at the way of heaven, and when former close friends are facing each other with weapons, in this battle to suppress demons across the country, the country, and the world, who can define the true right path?
"Remember this pain, become stronger in the future, and don't let others feel it again." The four words "Believe one's heart to one's heart" on the stone tablet hide the hottest moral principles in the world, and also hide the most tragic life toward death.
