The next step is to sit on the floor and let the air flow into his dantian, which is the part of the body that controls the flow of energy in the body. After a while, the dantian will feel hotter, indicating that the student has completed the previous step. The student thanks the master for his advice, and the master tells him that in ten days, he will arrive at the "first layer of heaven" . The master then gives the student a book called "divine celestial technique" , which describes the fundamentals of celestial cultivation. The book will help the student learn how to use the stars to harness their power. The next day, the student is amazed at the strength and willpower of his master and his fellow disciples. He asks the master if there is something he must discuss with him before he officially teaches him martial arts.
