Cause and Effect Sword Song

Five hundred years ago, a great catastrophe depleted the spiritual energy of heaven and earth, the immortals and gods fell, and spiritual practice was cut off. Five hundred years later, Xiao Chen, a young man at a drug store in Qingyun Town, discovered that he could see strange lines. The golden thread connects the childhood sweethearts, which is love; the black thread entwines the dying person, which is doom; the red thread buries the blood deeply, which is the unbreakable relationship. But the weirdest thing is the long dark red thread on his wrist that leads to nowhere and is always beating slightly. Every time he tried to cut off the death calamity above someone else's head, the thread would tighten a little. Until that day, he drew his sword out of its sheath, and the best friend from his previous life who had killed him to repair the law of heaven stood in front of him again. "Xiao Chen, the cause and effect in this world is a scale. If you save a person, the scale will be tilted by one point." Xiao Chen looked at the sword in his hand and said only one sentence: "Then let me see whether your heavenly way is stronger or my sword is stronger."
