There will be three parts in the Jianjia series, namely ancient times, the Republic of China and modern times. There will be connections between the three, but each will have its own characteristics.
The first book tells the story between Proton and the Prince in an imaginary era. There is pain and love in it, so it can be considered a serious drama overall.
The second and third parts are also being planned at the same time. If you like to read long novels, you may consider joining the series.
