Feiyan and Wuchen, the two masters of Xuanmen's weapon refining, are equally famous but diametrically opposed rivals. When Fei Yan was reaching the highest level, the bronze lamp he was trying to cast as his natal artifact was backfired by his inner demons. The furnace exploded and people died, and their souls were accidentally locked into the unfinished lamp.
This bronze lamp was bought by Wuchen at auction. When debugging late at night, he rubbed the wick with his fingertips and injected spiritual power, and he actually forced out the soul of Fei Yan in the lamp. "You are responsible for touching the wick!" An angry rebuke started the tug of war between the two of them who were forced to coexist.
The old enemy has become a prisoner in the palm of his hand, and his spiritual power is connected, making it difficult to break up the grudges. She relied on his spiritual power to survive, but he saw the scars of the past on her soul; she couldn't help but pointed out his omissions in the weapon refining, but he mocked her, but silently accepted her. The secret of the bronze lamp is gradually revealed - it was originally a twin device that required two people to build it together, and her death hid a shocking conspiracy.
From tit-for-tat to mutual dependence on rainy nights, from memory fragments to sharing life and death. When the bronze lamp turns into a twin spiritual weapon, the old enemy finally becomes a bond. They use the weapon as a proof to spend the rest of their lives together: "We will refine the weapon together for the rest of our lives, and we will spend the day and night together."
