Yun Zhao, the number one sword cultivator in the Three Realms, the master of Hanyue Palace, is as cold as a lonely moon. Three hundred years ago, she failed to protect her best friend's entire family; three hundred years later, she accepted the last bloodline of that family, Xie Wuchen, as her disciple.
The young man was cursed with death and knelt outside the palace gate for three days and three nights, just for a chance of survival. She taught him swordsmanship and gave him warm elixirs, but she also set the coldest rules when he started: "If you become a demon, no whole body will be left behind under the Hanyue Sword."
Later, the young man broke through the Underworld Lock and became famous all over the world. When the world-destroying conspiracy swept through, he resolutely stood in front of her. Yun Zhao smiled, as tenderly as on that snowy night:
"Wuchen, this time, it's Master who will protect you."
Even if the price is, the soul will be destroyed.
The plot is very good, please update
