Inside his mind he saw first a dark empty void and after millions of bright lights. As he went through this seen he was strongly convulsing and his body was oozing out blood out of every pore, but the blood was not fresh like from a wound but dark and filled with impurities. The world where this boy was born was based on qi and martial arts, where the strongest took all. And the state he was in was called cleansing the first step before starting to practice martial arts. In reality this step was one of the hardest, a martial artist would need huge amounts of money to buy pills and many other herbs to help them cleanse their body. There is a legend that long ago one of the great emperors who founded the empire, where the boy was born, had achieved a body which did not have a single impurity, thus he obtained the 'body of sages'. This allowed him to never be stuck at bottlenecks in his cultivation.
