Dinosaur Army in Another World

[Status: Completed] An earlier pet summoning novel. In the book, the protagonist brings a batch of dinosaur eggs through time, and as his mental power increases, he can continuously summon more powerful dinosaurs and crush the enemies. Overall, it is a fun book. In addition to the interesting and unique setting of summoning dinosaurs, I am afraid that there is nothing outstanding about this book either at the beginning or now. It has facial-looking characters, mentally retarded villains, and various shocking plots. Now that I think about it, it would be difficult for me to finish reading most of it if it weren't for the dinosaurs.
