Breaking the Road to Heaven

Why does the immortal magic disappear between heaven and earth, and why does the immortal in heaven insist on playing a chess game. Hundreds of years of secret planning, but it was decided to involve a young man in a small mountain village isolated from the world. Thousands of people in the world are practicing martial arts, and I can defeat them with one magical move. If the laws of heaven are not for the people of the world, I will cut off the way of heaven with one sword.
