Yin and Yang in Qin Dynasty

The only son of the royal family, who is less than one person and more than ten thousand people, enters the world not to fight for power, but to live a happy life. The daughter of a martial sage born with national beauty and familiar with ancient and modern times, she enters the world, not afraid of the storm with her feet, just for peace in the world. A mysterious young man with a mysterious life experience and extraordinary talent enters the world, not afraid of the powerful people in the world, and just wants to find the truth. A chivalrous heart and a group of young people form a world. Why don't you see young people smiling? It's just because the knights are drunk and old. The way of chivalry asks the sky, and all methods are cowardly. The young people in the world are chivalrous, but the world is pitiful and unknown. In the Qin Dynasty, the yin and yang rivers and lakes were full of energy, and the question in the heart of heaven has not yet ceased.
