Ten years ago, the young girl Mo Yi's family was persecuted by her biological father, the king of this country, and managed to survive at the expense of her friends and loyal servants. In order to re-rise the family and avenge everyone, he did not hesitate to become his father's enemy and change his name. He blended into the royal family and was adopted, and met the illusion boy. Ten years later, I discovered... The only place with illusions in the 21st century is a country where advanced hot weapons and ancient cold weapons coexist. She is a lonely island country, but it raises a group of the oldest peoples on earth. Excellent espionage technology; the emergence of elite killers and assassins is their proud capital. They are the only remaining bloodline of the Holy War tens of millions of years ago - the Six Families. The rest of the world doesn't know any of the above, they only know: this land is called "Xiyan". It means "If I leave, please smile like before." The story I want to tell is when the country of Xiyan was still called Linruoshuangchen.
