Ten years ago, the boy's father carried a sword to slay demons. The battle with the Demon Emperor lasted for three days and three nights. Finally defeated the Demon King. Just because his father failed to deliver the final killing blow with the sword, he allowed him to escape. He was despised by the world and hanged himself. Even the Tianmen where he was located was squeezed out and declined. Ten years later, the demons invaded again. The young man retraced his father's path and entered spiritual practice, just to complete the great cause that his father had not completed.
