The nine sons of Longsheng are all different. Yaizhen is the second prince of the Dragon Palace of the East China Sea. After returning from the tribulation, he found that his widowed sister-in-law was very misbehaved. He hated hiding evil and evil people the most in his life, but he could not be really cruel to his widowed sister-in-law.
Wenche is a hybrid between the Dragon Clan and the South China Sea Mermaid. He can give birth to offspring in a male body and carries a baby dragon in his belly. The baby dragon's father went through a tribulation but turned against him and refused to recognize anyone. Wenche is mute and cannot speak. In the end, he became disheartened and took the baby dragon to the mother clan.
PS, Wen Che was not Qiu Niu's servant, he was picked up by Qi Niu. Later, Qiu Niu died, and Wen Che and Yaizhen happened to have an affair. Yazhen escaped before he could announce it, and the young dragon was misunderstood to be Qiu Niu's. In fact, Qi Niu only showed kindness to Wen Che by taking her in, and she was not really a widowed sister-in-law.
