I, Jiang Muchen, am the top master in the Underwater World, known as the Ghost Doctor and Sword Fairy. The world admires and awes him. He is not a tester of the dark river, but a peerless master who broke into the dark river. Su Changhe and Su Muyu were trained and adopted by Anhe as unknown people. The two fought their way out of the siege of many unknown people in the battle on the Shura Road. Got the chance to really join Anhe, and got the surname Su at the same time. He went through the Hundred Ghost Cave Trial and became a survivor. In the life-and-death relationship with Su Muyu, he formed a deep bond with him. Rescued them both, taught them martial arts, taught them karma, and solved their doubts to create their own legend, and travel with them in the world!
