Blue sky strokes are worthy of their name. Liao Ke is confident that this book is worth reading, and it would not be an exaggeration to call it a classic if the entire book is read. The whole book is supplemented by love and the main thread is cultivation. The characters are described in detailed language, and I believe that the character's personality is grasped very accurately. It is by no means a self-cultivation book like a complete account. Just like the title, the delicateness can be reduced to micro strokes, and the vastness can describe the blue sky. Only two to four chapters are updated every day.
