Background / History

Gu Yu is Gu Rong's daughter, Han Feng's wife, and Han Yu's mother. Before Han Yu was raised by Gu Rong in the Seven Treasure Glazed Tile Sect, she and Han Feng traveled the continent in pursuit of an opportunity to break through to the Title Douluo realm. Her Bone Dragon martial soul contributed to Han Yu's inherited dragon bloodline. 1

While traveling with Han Feng at sea, Gu Yu helped ambush a badly injured Hundred-Thousand-Year Black Tortoise after it fought the Blood Soul Demon Shark. She used spatial teleportation to reach the Black Tortoise's shell and struck its fatal neck wound with a bone spike. 38

Gu Yu traveled with Han Feng to the Sun Moon Empire, where the pair studied Soul Tool crafting. They passed Yu Lingfeng’s introductory test through coordinated effort: Han Feng focused on reconstructing the circuit diagram while Gu Yu stood guard during his work. 64

During their studies, Gu Yu and Han Feng sought to obtain Soul Tool blueprints and technical knowledge before returning to the Douluo Continent. They studied increasingly complex circuit diagrams together and planned to learn the principles behind Level 1 through Level 7 Soul Tools. 79

After two years away, Gu Yu and Han Feng returned to the Douluo Continent as Title Douluo-level soul masters and Level 7 Soul Tool engineers. Their return reunited them with their son, Han Yu, and positioned them as major assets to the Ling Tian Sect during negotiations with the Sun Moon Empire. 81 83

After returning, Gu Yu learned Gu Rong's Soul Core condensation method alongside Han Feng. She later refined Immortal Herbs, reaching Level 96; the refinement also made her Bone Dragon martial soul more solid and showed faint signs of evolving toward a true dragon. 86 91

Gu Yu continued to support the sect alongside Han Feng and Gu Rong, including standing with her family against Yu Yuanzhen in Heaven Dou City. She also demonstrated a Soul Tool cannon before Emperor Xue Ye and Qian Renxue, helping secure the Heaven Dou Empire's purchase of fifty Level 4 Soul Cannons. 98 99

On Sea God Island, Gu Yu received the highest Sea God assessment among her family: the Sea God’s Nine Trials. After defeating all seven Sacred Pillar Douluo, she inherited the Vast Sea Cosmic Shroud and began her first assessment, climbing 333 steps of the Forbidden Land within one year. 159 160 161

After the Sea God Island expedition, Gu Yu returned to the Douluo Continent with her family and used Void Boundary to bring the group directly back to Ling Tian Sect. 166 167
