Must I Sacrifice My Lifespan to Summon an Immortal? My Enemy Pays the Price Instead

It's pretty good, very interesting, much better than those routine articles.

Update, the book is slow to gain popularity, there are few people reading it now, the book is very good, don't read the negative comments, it is really well written, don't give up, wait until there are more people, then go up, have confidence.

It's beautiful. I'll give you a little flower to support it.

It's so well written, my only regret is that there are too few of them, not enough to read!!! I hope the author can update fifty times a day!!!

Eye-catching

I read it in one sitting. It's pretty good. There's nothing toxic about it. It's fun to watch without thinking.

It's so well written, why did you cut it? I hope five-point praise can bring you back.

Very well written haha

It's innovative and relatively new, and it's pretty cool.

I don't know how to write comments, so use a few words instead, hahahahahaha
