Shui Jing was born on the shore of Hengshui Lake. He has shown an unusual closeness to the lake since he was a child. Once, he found a thousand-year-old turtle trapped in the lakeside weeds on the shore of Hengshui Lake. Shuijing was 5 years old at the time. In order to save the turtle, he dug out weeds, mud, and tiles with his hands until the flesh and skin of his hands were torn and the bones and flesh were separated. He forcibly moved the turtle weighing more than 200 kilograms little by little into the lake. The turtle entered the water and regained its vitality, turning into a young man and rescuing Shui Jing, who was unconscious from fatigue. The Divine Turtle is the son of Emperor Xuanwu. He was in trouble while searching for the Hengshui Lake Spirit Pearl and was rescued by the young Shui Jing. In order to repay Fairy Shui Jing for saving her life, she signed a master-servant agreement with young Shui Jing. Since then, Shui Jing has been inherited by Emperor Xuanwu and stimulated the water spirit root in his body. Accompanied by the Divine Turtle, he guarded the shores of Hengshui Lake as a casual cultivator, protecting humans from attacks by alien creatures. As the battle gradually escalated, Shui Jing became extremely violent and often beat alien creatures until he regretted his birth. He was called the "Great Demon King of Hengshui Lake" by the evil alien spirits. As Shui Jing grew up, Lin Miao collected enough water spirit beads, which attracted the attention of the Demon Suppressing Division. He was specially recruited into the Demon Suppressing Division, and formed the Nine Dragon Slaying Team with Jin Feng and others, and began the battle against the evil spirits from other lands.
