Background

Sun Yu was imprisoned in Qinghe County after stealing several taels of silver from the City Lord’s cousin. Lin Feng offered to secure his release in exchange for instruction in Iron Cloth Shirt and Thirteen Taibao Hard Gong, which Sun Yu accepted. 85

After Lin Feng released him and gave him fifty taels of silver, Sun Yu revealed that he had no home and intended to wander the jianghu. He chose instead to remain in Qinghe County, enter the martial-arts tournament, and seek a position in the Yamen. 87

Appearance

Sun Yu can assume human, hybrid, and full demonic-beast forms. His bloodline initially manifests asymmetrically before developing into more complete transformations.

• His first awakening covered the right side of his body and face in hard scales, while his left side became heavily muscled. 207
• He develops horns, vertical pupils adapted to darkness, sharp teeth, and scaled claws capable of shattering rock. 207
• His scales can withstand True Qi sword attacks and ordinary arrows. 207 253
• He has transformed into a Fire Qilin, a human-dragon hybrid, and a five-clawed fire dragon. 372 480 481

Personality

Sun Yu is fiercely independent and refuses humiliation even when faced with overwhelming power. When Dai Haoran demanded that he kneel and beg for mercy, Sun Yu spat blood at him rather than submit. 205

He has a strong instinct for justice and openly challenged the staged arena matches in Longyuan County. Once his opponent attempted to kill him, however, Sun Yu responded without hesitation or restraint. 176 177

His loyalty is especially pronounced toward Lin Feng and Little Gray. Little Gray’s death drives him to seek revenge and pursue greater strength, while Lin Feng’s repeated protection and guidance make Sun Yu regard him as both elder brother and, eventually, adoptive father. 204 205 442

As ruler of the Demonic Beast Royal Court, Sun Yu becomes more calculating and ruthless. He crushes rebellious tribes, replaces their chiefs, and uses marriage and appointments to consolidate his authority. 441 444

• Greatly enhances his speed, strength, senses, night vision, and resilience. 207
• Grants steel-hard scales, claws, horns, and dragon-like eyes. 207

• Lets him absorb useful metals and refined vital essence to replenish himself after breakthroughs. 252 253

Transformation

Sun Yu can shift between human and demonic forms through bloodline inheritance and the Ancestral Return Scripture.

• His lineage is descended from unions between humans and demonic beasts, allowing him to cultivate both Demonic Power and True Qi. 207

Ancestral Return Scripture

A lineage-specific True Qi art of the Blazing Fire Dragon King clan.

Before awakening his bloodline, Sun Yu was already trained in close-quarters combat and Hard Gong.

• Iron Cloth Shirt — taught to Lin Feng while Sun Yu was imprisoned; strengthens resistance to attacks through physical conditioning. 85
• Thirteen Taibao Hard Gong — another Hard Gong art Sun Yu exchanged for his release. 85
• Eagle Claw Technique — his signature unarmed technique; he used it to defeat and cripple an arena champion after his sword broke. 177
• Basic Swordplay — learned from Lin Feng after joining the Mayi Guard, though he considered swordplay inferior to his fists and feet at the time. 177

• Two treasure swords bearing the Demonic Sword Mark can directly injure soul bodies. 703
• He was unable to resist Mu Chenxiao within his Sea of Consciousness and required Lin Feng’s rescue. 482

Equipment / Weapons / Items

• Little Gray — Demonic Beast companion. Its death at Dai Haoran’s hands triggered Sun Yu’s quest for revenge and awakened his bloodline when its blood merged with his skin. 204 207
