Thousands of years ago, the heavenly war god Xiao Che and the flower spirit fairy Ling tide met under a peach blossom tree for the first time. They fell in love secretly, but due to the conspiracy of the second prince and Wen Quxing, they fell into the unjust case of "liaison with the demon clan". In order to protect Lingxi, Xiao Che gave up the power of the God of War and fell into a thousand-year calamity; Lingxi was thrown into reincarnation and lost all her memories. Only a Dooming bell made by Xiao Che with his own divine power accompanies her through the ups and downs of the world.
Thousands of years later, in the Mobei military camp, Xiao Che, a mortal general who had experienced many calamities, and Lingxi, who had transformed into an ordinary woman, unexpectedly reunited. From market fireworks to lanterns, the two renewed their relationship amidst the fireworks in the human world, but they were also involved in crisis again because of the shadow of the old case in heaven. On the Immortal Killing Stage, the truth gradually emerged, and the true identity of the second prince's demon clan was exposed. Xiao Che and Lingxi joined hands to fight against the enemy, but because Lingxi used the Dueling Bell many times, the immortal energy was exhausted and on the verge of dissipation.
In order to save Lingxi, Xiao Che gave up the glory of returning the God of War, stepped into the dangerous Forgotten River, exchanged a thousand years of life for the Flower of the Other Side, and used a hundred years to nourish his immortal soul with the power of the God of War day and night. After a hundred years of guarding, the soul finally awakens. The two immortal souls are bound and follow each other in life and death. However, not long after the peace, the remaining magic power of the second prince polluted the spiritual veins of the heavens, and a catastrophe was imminent. At the critical moment, Xiao Che and Ling Xi worked together to resonate with the God of War sword with the bell of crossing the evil spirit, purifying the magic power, resolving the catastrophe, and finally achieved perfection.
A hundred years later, the fairy palace in the heaven is full of peach blossoms. Their children have inherited the immortal power and divine power, and the family shares a family relationship. This bell that has witnessed thousands of years of suffering and deep love is still ringing softly in the wind, telling a legend that spans life and death and will never leave.
