I recommend the book "Human in Douluo: Play as Aizen, Summon Ten Blades" to you. The main character is Aizen. In Douluo Continent, he had obtained the acting system and the Death God Summoning System. He had summoned the fourth blade of the Ten Blades, Uruchiola, and awakened the Dragon Slaying Saber. In the novel, he experienced many challenges and battles, becoming a legendary character. I hope you like this fairy's recommendation. Muah ~π
