The Solitary Lamp Obeys the Orders and Does Not Illuminate the Remaining Feelings

I am a descendant of Marquis Wu, and my family has a secret technique that defies heaven: lighting a seven-star lamp to extend your life. This technique requires the caster's essence to make up for the remaining life of the dying person. My husband, Wei Pingchuan, was wounded by seven arrows while protecting me on the battlefield. Before he died, he held my hand, his eyes full of reluctance: "Shao Ying, I only regret that... I couldn't accompany you to see the day when the world is unified..." I was heartbroken and cast a spell to save his life. I thought that after he recovered from his serious injury, he would return to the front lines and fight alongside me. But until I returned from the victory, he, who was supposed to be recuperating in the rear, disappeared. Finally, guided by the burned-out wick, I found a villa in the mountains. The courtyard is filled with red silk, and Wei Pingchuan is tenderly tying a hairpin in a woman's hair. I recognize that woman. She was Cai Ling, his late mother's maid. Cai Ling nestled in his arms and whispered softly: "General, if Madam knew..." Wei Pingchuan lightly covered her red lips and murmured in a low voice: "Only after death can you realize that the justice of your family and country is too tiring." "From now on I will only live for you." I stood outside the window, the cold wind penetrated my bones. It turns out that I sacrificed myself to prolong his life, but what I was prolonging was his marriage to someone else. He wants true love, but he doesn't know that this life-extending technique relies on mutual agreement. If the hearts are different, the contract will be broken. If the contract is broken, life will not last long...
