In the thirteenth year of Dajing and Yong'an, Su Qingci, a scholar from a poor family, broke into the green cliff of the "Monster Mountain" with the "soul-inducing lamp" left by his mother to save his wronged father, and accidentally met the thousand-year-old snake demon Xuanyuan who guarded this place.
Xuanyuan was betrayed and his tribe was destroyed for saving humanity, and he has since sealed his heart with indifference. However, he was forced to go with him because of the soul-inducing lamp in Su Qingci's hand and the deal to "unlock the memory seal". On the way to find grass, Su Qingci saw Xuan Yuan's gentleness in protecting the young demon, which broke his prejudice against "demon"; Xuan Yuan was also moved by Su Qingci's tenacity, and his dust-laden memories gradually awakened.
After coming down from the mountain, Su Qingci was caught in the crisis of being framed by a "demon", and Xuan Yuan transformed into a human and sneaked into the capital to protect him. The two shared life and death during the investigation - Xuan Yuan was exposed and his true body was not abandoned, and Su Qingci even sacrificed his "spiritual vision" to conclude a "spiritual contract" to save him. Faced with the villain's conspiracy to "seize power by killing monsters" and the dead end of "human-monster confrontation", they work together to find the truth about "the coexistence of humans and spirits", finally break their fate, stay together on Qingya Mountain, and complete two-way redemption.
Purpose: Breaking prejudices and labels
