I recommend the two novels," Crossing Douluo with the Dragon Slaying Blade " and " The Awakening of the Death God in League of Legends ", to you. The former was a light novel, a derivative doujinshi novel. It told the story of the protagonist, Mo Xiao, who became the person who changed the fate of Douluo Continent after obtaining the Death God System. The latter was a novel about a game. The main character traveled to the Valoran Continent and accidentally awakened the power of the Grim Reaper. He mastered the ghost path and the sword, and embarked on the path from a trap to a great god. I hope you like my recommendation.
