When it is slightly dry and the friction increases, you will find a bulge between your fingers. At this time, the air sinks into the abdomen, the rubbing speed is accelerated, and the concave and convex feeling of the fingertips is getting stronger and stronger. Fingers are rubbed instead, and the strength is reduced. Soon, you will have spiral pills. The key is to rub, one hand does not understand, one hand bends and buckles on the other hand, and draws a small circle clockwise on it. When it increases to the speed of sound, it will produce a sonic boom first, and don't stop.
At this time, when the qi is cut out, you will continue to accelerate to the first cosmic speed. At this time, you will feel a little floating, don't stop. If you don't come out, you will float, and then you will continue to accelerate. When you reach the speed of light, you become the speed of light. Don't exceed the speed of light at the forefront, or you will be a superman light wave.
