The old man was silent for a long time, Phuong Du Du said: "Since the fusion of heaven and earth began, there must have been holes in the play, we must observe, observe to be able to smash them, using methods Hey, a saint is also a saint, a saint is a messenger of heaven and earth, there is no one in this world." When you achieve it, hide it and wait for the right time; When you get there, make a plan, you can go up and down, you can go down, and follow that to guard heaven and earth."
