Background / History

Lin Yu was reincarnated into the Douluo Federation after being struck by a truck. He grew up as the only son of Aolai City Lord Lin Qingye and received a private martial soul awakening on his sixth birthday. His awakened martial soul, the Jade-Scaled Seven-Extinction Flower, was a superior mutation coveted by plant-type Soul Masters; he also possessed innate full soul power. 1 2

Lin Qingye used personal connections and significant concessions to obtain a first soul spirit for him from the Spirit Pagoda. Lin Yu chose and subdued the experimental Poison Angel, a poison-element soul spirit made from poison-type Soul Master genes, then successfully fused with it despite its resistance. 3 4 After learning that the Spirit Pagoda had crippled his father and created such soul spirits through lethal experimentation, Lin Yu decided not to join the organization. 5 6

He chose Red Mountain Junior Soul Master Academy over Violet Private Noble Academy, preferring the public-school path despite its risks. While studying there, he encountered Na'er being watched by suspicious men, used his guards to have the men arrested, and brought her temporarily into the Lin residence. He later personally enrolled her at Violet Noble Academy. 6 7 8 9

Recognizing Battle Armor's future importance, Lin Yu chose blacksmithing as his secondary profession. He apprenticed under the level-seven forger Qi Feng, trained through demanding hammer work, and developed into a third-rank forging master capable of Thousand Refinements. 10 11 12 13 21

After graduating from Red Mountain Academy, Lin Yu entered Eastsea Academy. He immediately entered the Spirit Ascension Platform to raise the Poison Angel to the thousand-year level, defeating a Black Albatross, Human-Faced Demon Spider, and Dark-Gold Dreadclaw Bear. He obtained and fused with the bear's palm soul bone, which mutated in compatibility with his martial soul. 15 16 17

At Eastsea Academy, Lin Yu was assigned to First-Year Class One and selected alongside Wang Jinxi and Zhang Yangzi for the class's promotion-match team. He also became acquainted with Tang Wulin as a fellow young forger and Xie Xie as a fellow student. 18 19 21 23

During the Sea Dragon Bone auction attack, Lin Yu detected poisoned drinks, escaped with Xie Xie through the ventilation system, and killed an Evil Soul Ancestor by forcing amplified Jade-Scaled Seven-Extinction Flower poison into his mouth. He recovered a storage ring and a map of the Eastsea Boat Guild Hall from the corpse. 24 25

Personality

Lin Yu is calculating and long-sighted. He weighs institutions, personal connections, cultivation resources, and future threats before making major choices, including rejecting the Spirit Pagoda, choosing blacksmithing, and planning a future route through Shrek Academy. 5 10 19

He is protective toward people he considers vulnerable, particularly Na'er, and is dissatisfied with laws that minimize crimes against those without social status. 7 8 9 However, his sense of justice does not prevent him from using lethal poison or taking valuables from defeated enemies when the situation demands it. 15 25 26

In formal sparring, Lin Yu exercises restraint. He avoids deploying his martial soul's full poison against fellow students, relying on vine techniques and forging hammers instead. 20 21

Abilities & Skills

Jade-Scaled Seven-Extinction Flower Martial Soul

Lin Yu's plant-type martial soul manifests as dark vines supporting a jade-green flower bud with nine seven-fingered leaves. It is an exceptionally poisonous martial soul and a treasure among plant-type Soul Masters. 1

• Can form and manipulate vines even without soul skills, using them as whips, restraints, or extensions of his body. 4 16
• Its natural poison gives his vines a sickly sweet, dangerous aura and causes numb, itchy pain even when he does not deliberately release venom. 7 20
• Its corrosive poison can melt metal, destroy organic structures, and dissolve a victim's limbs after death. 9 16 25
• Lin Yu can precisely direct parasitic vines after they grow on a target, allowing him to restrain or destroy targets from within. 15 16

Corrosive Poison Power

His first soul skill strengthens the corrosive poison carried by the Jade-Scaled Seven-Extinction Flower. 9

• Melts Violet Noble Academy's metal gate under vine constriction. 9
• Combines with parasitic vines to corrode a target's internal body structure. 15 16
• Can be withheld during sparring to avoid seriously injuring human opponents. 20

Parasitism

His second soul skill grows Jade-Scaled Seven-Extinction Flower vines directly on a target. 15

• Entangles targets by binding their wings, neck, or limbs with independently controlled vines. 15
• Leaves poison sources attached to the enemy rather than requiring Lin Yu to remain close. 15
• Can create a Jade-Scaled Seven-Extinction Fruit after the parasitic growth cycle; Lin Yu uses such a fruit to poison the Dark-Gold Dreadclaw Bear. 16 17

Poison Power Enhancement

Lin Yu's third soul skill amplifies both his first and second soul skills. 25

• Doubles the toxicity of Corrosive Poison Power and Parasitism. 25
• Doubles his own strength and speed while active. 25
• Its amplified venom kills an Evil Soul Ancestor after the opponent bites one of Lin Yu's vines. 25

Dark-Gold Dreadclaw Bear Palm Soul Bone

Lin Yu fuses the Dark-Gold Dreadclaw Bear's golden palm bone into his hand after defeating the beast in the Spirit Ascension Platform. 17

• The fusion painfully shatters and reforms the bones in his fingers. 17
• Grants noticeably greater hand strength. 17
• Draws on his soul power and appears to trigger a compatible mutation in his poison-element plant martial soul. 17
