Yun Jin was adopted by Jiang Yehu since he was a child and regarded him as a father. However, on the night he came of age, he discovered that there was a blood edict hidden in his master's ashes - that was the truth about his family being wiped out, and it was clearly signed by Jiang Yehu. He remained silent for three years, practicing forbearance, and finally unveiled the blood-stained runes at the sect ceremony. The blood was shining in the sky, and the truth was like a blade. His former mentor was actually the culprit who slaughtered his whole family; and he was just a tool of revenge that had been raised for ten years. Now, the sword is silent and the soul is ablaze. What Yun Jin wants to ask is not why, but - are you worthy to be my master?
