I recommend the two books," Pet Manipulation Fantasy World " and " Beast Tamer, I Can Make Magical Beasts Evolve Unlimited." They were both game-type novels. The main characters had the ability to control all kinds of powerful magical beasts. The plot of " Beast Tamer, I Can Make Magical Beasts Evolve Unlimited " also involved the evolution and leveling of magical beasts. I hope you will like these novels.
