According to the information provided, I recommend the Xianxia and Cultivation novel, Map of the Universe. This novel described a protagonist who had traveled through two different time and space. He encountered an era where the world of cultivators was filled with experts. He coexisted with immortals, demons, Buddhas, demons, witches, and other experts. In this great era, peerless talents burst out with dazzling brilliance. Although there was no explicit mention of the Heavenly Demonic Code, Xiao Tong, Xiao Daokun, and Xiao Daogan, this novel has elements such as heaven and earth, cultivation martial arts, and so on. You might like it. I hope you like my recommendation.
