I've already read Violent Summoner and Summoning an Army.

Answer 1

Yo ~ Looks like you're a summoner! Then I'll recommend you a book that I personally like,"European God Summoner"! This was a novel about a game. The main character, Chu Ziheng, had transmigrated to the game world and became a summoner. However, he did not immediately start summoning. Instead, he tried to escape from the game world. The plot of this novel was compact, the summoning gameplay was rich, and the characters had distinct personalities. Moreover, it was already over! I hope you like my recommendation, Muah~
