Great Book Recommendations (Complete Books and Serialized Book Lists)
好书大推荐（完本和连载书单）
Because I have been very busy in the past two years, the book list has hardly been updated. It is 2023, and I am planning to redo everything. To be honest, in the past two years, authors have become less and less good at naming. Many books with terrible names that I accidentally discovered when I was bored are actually quite well written. I am really speechless.

Bourne Book Club 1 group 833528943, Bourne Club 2 group 879936725 Bourne Club Master 940510849
The recommendation index is four and a half stars. The content of the anti-Japanese espionage war has been completed. Uncle Teng's writing skills are very good. Although the protagonist's abilities were a bit off-putting at the beginning, they were no longer used in the middle and later stages, and the previous ones were slightly modified. The only flaw is that the work is subject to problems. , The ending was rushed, some lines were not explained clearly, it has an open ending, the supporting characters are also very good, their IQs are all online, there is a heroine, but she can almost be regarded as non-existent, the reason for giving half a star is that the ending is rushed, strong recommendation, please bring your own tissues for some of the plots in it.

Ah Fu feels that he has been inextricably linked to the word "substitution" in his life. When encountering good things, you will always be pushed out by others; when encountering bad things, you will always push others aside. Pushing her back and forth, all the way into the palace == Her wish is to see less, listen less and talk less, survive in peace until she leaves the palace, find an honest and obedient man to marry, and live the rest of her life well. My simple wishes were challenged again and again. I saw things I shouldn't have seen, heard things I shouldn't have heard - and said things I shouldn't have said. The person I was probably going to marry was not who I originally imagined! However, perhaps the reason why life is beautiful is because we don't know the future...
