My answer might be a little vague. Douluo Continent was a very popular fantasy novel. There was no official announcement of a sequel yet. However, if he was referring to the novel "Douluo Continent: The Legend of the Douluo Heroes" or "Douluo Continent: The Peerless Tang Sect", then although they were not direct sequels, they could also be derived from the Douluo Continent and have a certain degree of story independence. "The Legend of Douluo Heroes" told the story of Tang San's time on Douluo Continent, the rise and disputes of the various spirit master clans on Douluo Continent, as well as the legendary experiences of the protagonist and other spirit masters. The Peerless Tang Sect mainly narrated the story of the main character Huo Yuhao on Douluo Continent and his struggles with the other soul masters. Although it didn't have the intention of directly continuing Douluo Continent, it was still a very popular fantasy novel with many readers.
