Light and dark, heads and tails of one coin.  The Rules and Morals drove humans to civilization. At the same, it was the shackle for humans.  Those who followed the rules and morals were great heroes.  Those who rebelled against rules and morals were great evils.  Yu Xuan was not a psychological expert, but he understood the depths of human nature.  A great hero or a great evil was just a human's opinion. Yu Xuan loved the rules and morals, but he was not bound by them.  In this world where strong reigned the supreme, justice was a strength!  This was a journey of, Yu Xuan, a normal disciple of the Five Elements Sect, who had a rebellious thought against the world. He knew the rule of right and wrong, that was just a method. However, his goal was not to do good deeds or bad deeds, it was to seek the meaning of life.  He wanted to know the depths of things behind life.  What is life?  Where is life from? When is life first appearing? Why is life different? Which life is real life? How is the first life form?
