Background

Yu Xiaogang was originally a wealthy heir on Earth. After dying in a plane crash, he transmigrated into the body of Yu Xiaogang on the Douluo Continent. The body he inherited belonged to a man ostracized by the Blue Electric Tyrant Dragon Clan for poor Martial Soul aptitude, separated from Liu Erlong after discovering their blood relation, and left dependent on others despite his extensive Martial Soul knowledge 1.

Recognizing that Tang San's enrollment at Nuoding Junior Soul Master Academy offered a route to power, he accepted Tang San as his disciple and bound him through the Master-Disciple System. The system allowed him to learn from his disciple's abilities and gain strength through disciple-related entries and quests 1 2.

His research and teaching eventually validated the Ten Core Competencies of Martial Soul theory through Shrek Academy's Seven-in-One Fusion Skill. The achievement ended a long-standing obsession and made the title “Master” known throughout the Soul Master world 43 45.

After returning to the Blue Electric Tyrant Dragon Clan more than twenty years after his expulsion, Yu Xiaogang completed its trials, defeated Soul Emperor Yu Xiaotian despite being a Soul Ancestor, and was inducted as a clan elder 51 52 55 56.

Appearance

Yu Xiaogang initially appeared as a thin, ordinary-looking middle-aged man with a lazy, somewhat decadent gaze. He had short black hair parted three-seven and looked around forty years old 1.

After consuming the Nine-Rank Purple Ganoderma and undergoing later physical transformations, his wrinkles faded and his body returned to a youthful, roughly twenty-year-old state 22 37.

• Short black hair; later manifests blue hair and lightning-lit pupils when using the Blue Electric Tyrant Dragon 3.
• Dragon transformation produces scaled dragon claws and an electrically charged aura 3.
• The Magic Spider Compound Eye manifests as a golden vertical pupil at the center of his forehead after later evolution 89.

Personality

Yu Xiaogang is ambitious, calculating, and highly conscious of the opportunities created by his transmigration. He initially views Tang San's potential as his means to pursue immortality and godhood, but repeatedly acts to protect and guide Tang San as a genuine master 1 39.

He is a meticulous theorist and strategist. In battle, he studies opponents, revises failed approaches, and uses illusionary quests to refine techniques rather than relying solely on raw Soul Power 3 9 68 72. He also has a strong affection for talented students and rapidly develops cultivation plans for those with potential 11.

Despite his pragmatism, he is loyal to Liu Erlong, Flender, Tang San, Xiao Wu, and his clan. He chooses to aid Xiao Wu despite the risks of changing established events and openly threatens conflict with Bibi Dong if Tang San is harmed 39 40 42.
