Reader comments
The method of returning gold to elixir mentioned in this book is very interesting. Although I have not actually tried it, I can feel the magic in it through the author's description. Moreover, the book emphasizes the rigor of experiments, which reminded me of my own experience in scientific research, which requires constant trial and verification. However, some terms and concepts in the book may require further explanation and research. Overall, this is a book worth reading that can expand our horizons and thinking.
