The little fairy Yan An practiced under the name of Zhang Youren, a Taoist master on the top of Zhongnan Mountain. Out of compassion, she stayed up all night to help treat a skylark bitten by a wild cat and fell asleep in class.
Master Zhang Youren said that Yan An, you saved Skylark at night, you have a compassionate heart and you are the foundation of Taoism. But all things in heaven and earth have their own order. Now, because of a single thought of compassion, you are confused between morning and dusk, neglecting your studies, and you are not distinguishing between the important and the important. "
Therefore, he threw the little fairy Yan An into the illusory sea of forgetfulness developed by himself to experience, and told her: "Those who enter must go through the tribulation of seven emotions and six desires, and the way to break the situation is hidden in the word 'merciless'. This situation is a ruthless game for you. "This is the origin of the title of the book.
After entering this illusory sea of forgetfulness, Yan An lost all his magic power and magic weapons, and even started to feel hungry. Later, there were aliens, fox demons, Due Hall, and Xiao Xinghe, a handsome boy from Dali Temple, waiting on the way to explore. They also collected mysterious beasts and experienced love disasters. But how will she break through this illusion and return in the end? ...
Intention: Being ruthless is not about being cold-hearted, but about breaking through the emotions and not being bound by them.
