"Douluo's Vanishing Shadow Douluo", the main character of this book, Luo Ying's first spirit was the Hand of Heaven's Favorite, his second spirit was black gas, unrelated to iron. But I believe you might like these novel recommendations: - <Douluo's Bright Angel>: The main character's martial soul is the Wings of the Bright Angel. It has the ability to summon an army of angels. It's exciting. - "Douluo's Iron Cutting First": The main character's martial soul is Iron Cutting First. It can cut through the hardest material on the Douluo Continent. The battle scene is very shocking. -《Douluo's Mysterious Spirit Master》: The main character's spirit is a mysterious spirit master, and can use telepathy to recover and transform other spirits, very creative. I hope you like this fairy's recommendation. Muah ~😗
