Can you recommend a few novels that are more in-depth but not difficult to understand?

I recommend the following novels to you: 1. "Back to the Tang Dynasty as an Alchemist": History-Two Jin, Sui and Tang Dynasties novels, alchemy as the main plot, more meaningful. 2. <<Brush and Ink>>: Fantasy-Oriental fantasy novel. The world view of the book is respected. It covers all kinds of theories and has more depth. 3. "St. Phalos 'Teaching Notes": Light novel-original fantasy novel. In the process of the protagonist establishing the academy in the foreign world, not only did he impart knowledge, but he also covered some thoughts about education and human nature. I hope you like this fairy's recommendation. Muah ~😗
