Can you recommend some popping balls doujin novels?

I recommend "The Best Special Shot Era" to you. The main character of this novel, Meng Lang, is making so much money in a world where there are no pirated copies. He has made Balala the Fairies, Armor Warrior, Masked Rider, and so on. He has become the king of special shot series and the favorite man of children. I hope you like this fairy's recommendation.
