Summon an Army

I read it many years ago. I remembered this book while reading other novels, and suddenly wanted to read it again. It reminds me of my school days. A very good friend recommended it to me at the time.

I watched a summoning work a few years ago. Now I can see that the writing style is still very strong. It's a pity that the content at the end is sloppy and the characters are ruined. But it's still worth watching.
