Yu Xiaogang

Biodata

Background and History

Yu Xiaogang’s Blue Lightning Tyrant Dragon Martial Soul underwent a malignant mutation into the pig-like Luo Sanpao. His cultivation remained below level thirty, and his oldest Soul Ring was only a hundred years old 16.

At Shrek Academy, he watched Xiang Bei’s technological achievements through the sky screen. Initially astonished by Xiang Bei’s creation of life, he imagined taking the young man as a disciple and combining Soul Tools with his own theories. After Xiang Bei chose mines over a Level 9 Fixed Soul Guidance Shell, Yu dismissed him as unworthy of becoming his disciple 3 8.

The Heaven Dou Crown Prince supplied metal for Shrek’s Soul Tool research and invited Yu to become dean; Yu subsequently headed the academy’s Soul Tool division. Despite this role, he urged Tang San to concentrate on Soul Power cultivation rather than Soul Tools 5 6 9.

Radiation baptism

After seeing Sword Douluo’s strength increase through radiation, Yu sought the same treatment, believing it would restore his Martial Soul as a Radiant Sacred Dragon. He entered the heavily irradiated area despite Flender’s warning, but quickly lost consciousness and was returned to Shrek 23 24 25.

Healers found severe internal damage and warned that he might never be able to have children. Luo Sanpao had undergone another malignant mutation, leaving Yu unable to use Soul Skills; an examination also found that his Sacred Dragon bloodline had been completely tainted. He subsequently lost his position in the Golden Iron Triangle 25 26.

Yu nevertheless encouraged Tang San to undergo radiation baptism. Tang San’s Martial Soul mutated and gained new properties, but his Soul Power fell by three levels. Yu celebrated the result as proof of his theory, unaware of its full cost 25.

Personality

Yu is proud of his theoretical reputation and eager for recognition. He celebrated the sky screen’s revelation that Tang San would become the Sea God, but panicked when a future scene showed no statue of him and he feared Tang San had not taken him to the Divine Realm 7 10.

He often reacts defensively when evidence challenges his theories. He rejected the demonstrated increase in Soul Ring age as fake and argued with Di Tian over the nature of million-year Soul Beasts. Although he promised Tang San more freedom after their disagreement, he privately resented being questioned 16 20.

Abilities and Skills

Martial Soul: Luo Sanpao

Luo Sanpao is Yu’s pig-like mutated Martial Soul. Before radiation, it retained a Sacred Dragon bloodline; afterward, it developed dark-purple fur, a second head and two additional legs, with bone exposed in places 16 24 25.

• Yu’s cultivation had remained below level thirty, and his oldest Soul Ring was a hundred years old 16.
• Following the radiation-induced mutation, he retained Soul Power but could no longer use Soul Skills 25 26.
• Before the mutation, his Sacred Dragon bloodline enabled a Martial Soul combination skill with the Golden Iron Triangle 25.

Martial Soul and Soul Ring theory

Yu proposed an optimal Soul Ring configuration based on his research and planned the ages and types of Soul Rings Tang San should obtain. Under his instruction, Tang San broke through level thirty and acquired a three-thousand-year Soul Ring 9 16 20.

• Yu maintained that a Soul Ring’s age was fixed upon absorption, even after the sky screen showed a method of increasing it 16.
• He identified an Ice Silkworm as being at least a hundred thousand years old; its later revelation as a million-year Soul Beast led to public criticism and a dispute with Di Tian 19 20.
• He claimed Soul Tools depended on a Soul Master’s cultivation and argued that cultivation should take priority over external tools 5 6.

Equipment

• Twenty-Four Bridge Bright Moon Night — An item Yu gave to Tang San while urging him to reach the Titled Douluo realm and pursue his future as the Sea God 7.

Relationships

• Tang San — Yu’s disciple. Yu focused on helping him become a god, while Tang San grew increasingly skeptical of his teaching and restrictive training 7 14 20.
• Flender — An associate at Shrek and fellow member of the Golden Iron Triangle. He tried to stop Yu’s radiation baptism and helped arrange treatment afterward 24 25.
• Liu Erlong — A fellow member of the Golden Iron Triangle who was distressed by Yu’s prognosis after the baptism 25.
• Xiang Bei — The young engineer Yu watched through the sky screen. Yu first wanted him as a disciple, then criticized his decisions and challenged his discoveries 3 8 16.
• Di Tian — A Soul Beast ruler who publicly disputed Yu’s theories. Yu feared Di Tian’s threats and later asked Tang San to kill him after becoming a god 19 20.
• Dugu Bo — A critic who mocked Yu’s cultivation and questioned his credit for Tang San’s future achievement 19 20.
• Ning Fengzhi — A supporter of Shrek who praised Yu publicly; he also valued maintaining good relations because his daughter studied at the academy and Tang San was Yu’s disciple 4 19 27.
• Bibi Dong — A figure from Yu’s past who expressed contempt for him when his name was mentioned 18.
