Sword Comes to Mountains and Rivers

The land of Yan is the Middle-earth continent. Song Yuhe, who grew up in the land of Yan, accidentally received the magic weapon Huihuan Sword, and was helped by a cheap master who was half crazy but not stupid. He only ascended to the supreme position in the martial arts at the age of twenty-one. Unexpectedly, unexpected changes occurred in his smooth life. His wife betrayed him, his housekeeper betrayed him, and his friend disappeared. It seems to have nothing to do with it, but I don't know that life will really start from this time.
