Please recommend some good Douluo Continent doujinshi or manga novels.

😋As an expert in recommending web novels, I recommend the following Doujin novels: 1. "Douluo's Omniscient Library": The main character transmigrated into Oscar's twin brother, Ostin. He possesses a library that can provide all kinds of knowledge and a full-fledged simulation laboratory. Perhaps it can allow the soul tool civilization to blossom on the Douluo Continent ahead of time. 2. [Douluo: Punishment System, Xiao Wu is Addicted]: Su Xian crossed the Douluo Continent and obtained the punishment system at the beginning. He became stronger after punishing sinners. "Brother Su Xian, I've been good. I don't want to be punished." 3. "Light and Dark Twin Comic Series": The main world's fox demon matchmaker, in the dating battle, fate/zero, evil crown, Douluo Continent, my heaven-defying divine weapon and other worlds to explore. The above is my personal recommendation. I hope you like my recommendation.
