Background / History

Yu Chenglong was born to an ordinary collateral-branch family of the Blue Lightning Tyrant Dragon Clan. His parents named him in the hope that he would awaken the clan's famed dragon martial soul and elevate their family into the clan's core. Instead, he awakened Nightmare, a creature resembling Yu Xiaogang's infamous Three Puffs martial soul. 34

Because Yu Xiaogang had failed to surpass level 29 with a similar martial soul, the clan treated Nightmare as inherently useless. Yu Chenglong was abandoned with minimal resources, ridiculed by relatives and peers, and grew to resent Yu Xiaogang for making others dismiss Nightmare before Yu Chenglong could prove its potential. 34 35 213

After reaching Rank 20, Yu Chenglong found a wounded Demon Tumor Tree in Sunset Forest—unaware that Du Bai had previously injured it. He killed the beast, absorbed its 700-year soul ring, and obtained its rare head soul bone. The encounter gave Nightmare's poison skills a major increase in effectiveness and became the turning point in Yu Chenglong's life. 35 37 410

He began fighting at the Heaven Dou Soul Fighting Arena for resources and experience, using poisonous mist to control confined battlefields. His victories drew the interest of several academies, including Heaven Dou Imperial Academy, while also earning him a fearsome reputation among arena opponents. 213 457 597 598

Yu Chenglong later recognized Du Bai as the unknown benefactor responsible for the Sunset Forest opportunity. Rather than swear service as a subordinate, he asked to become Du Bai's disciple, openly revealing his concealed head soul bone as proof of his sincerity. Du Bai accepted him, and Yu Chenglong swore loyalty to both Du Bai and Bibi Dong. 410 412

Under Du Bai's guidance, Yu Chenglong overcame the cultivation barrier associated with Three Puffs, reached Level 30, and acquired a third soul ring. He subsequently demonstrated that Nightmare could threaten opponents far stronger than himself, including poisoning a Soul King with his layered toxin techniques. 629 662 727

Appearance

Yu Chenglong is tall and lean, with a handsome but thin face, sharply defined features, and pitch-black eyes. His weathered appearance reflects the hardship and rejection he experienced while growing up. After absorbing the Demon Tumor Tree's soul ring and head soul bone, he developed a faintly sinister aura and eerie green eyes when using his poison-related abilities. 35 37 410

• Tall, slender build.
• Sharp-featured, thin face.
• Dark eyes that can turn green during soul-bone activation.
• Initially appeared disheveled after pursuing the Demon Tumor Tree. 35
• Became visibly sturdier after continued cultivation and arena training. 599

Personality

Yu Chenglong is determined, competitive, and deeply unwilling to accept the judgment that Nightmare is worthless. Much of his ambition is driven by a desire to overturn the humiliation he endured from the Blue Lightning Tyrant Dragon Clan and prove that Yu Xiaogang—not Nightmare—is the failure. 35 36 213

Despite his resentment, he is generally quiet, gentle, cautious, and respectful toward people he trusts. His difficult upbringing made him attentive to danger and reluctant to expose valuable information, such as his head soul bone. 280 614

He is intensely loyal to Du Bai, whom he views as both benefactor and teacher. Yu Chenglong repeatedly prioritizes becoming strong enough to reduce Du Bai's burdens and avoids disgracing his teacher through reckless conduct. 457 599 727

Abilities & Skills

Nightmare

Nightmare is Yu Chenglong's physically manifested beast martial soul. Though it initially resembles the despised Three Puffs martial soul, it can be raised like a pet and has developed into a poison-based control martial soul. 35 723

• Possesses light-brown fur and pale-blue eyes; its aura strengthened after absorbing the Demon Tumor Tree ring. 35

• Was initially underestimated for its comical, fart-based attacks and resemblance to Three Puffs. 34 723

Demon Tumor Poison Mist

• Creates a poisonous fog that impairs visibility and restricts enemy movement. 36 597
• Can cause Soul Power leakage, flatulence, diarrhea, and severe public humiliation in poisoned targets. 36 597
• The poison can enter through pores as well as the nose and mouth, making masks insufficient protection. 597
• The Demon Tumor Tree head soul bone increased the poison's effects by 200%. 37
• Before its enhancement, Green Tumor Poison Mist was largely ineffective against opponents at Yu Chenglong's level or above. 35
• It is most dangerous in enclosed arenas; opponents have greater opportunities to evade it in open terrain. 598

Demon Tumor Bomb

Yu Chenglong's Second Soul Skill condenses and releases poisonous mist as a bomb-like attack. It came from the 700-year Demon Tumor Tree soul ring. 35 410

• Strengthened the effectiveness of Green Tumor Poison Mist by 80% upon acquisition. 35
• Can rapidly thicken the battlefield's toxic fog and pressure opponents into surrendering. 597 725
• After the head soul bone fusion, its poison became comparable in potency to Demon Tumor Poison Mist. 37

Demon Tumor Eye Gaze

A skill granted by Yu Chenglong's Demon Tumor Tree head soul bone. 37

• Turns his eyes eerie green upon activation. 410
• Allows him to strike an opponent after meeting their gaze. 37
• The head soul bone was kept secret because its exposure could attract lethal attention from other Soul Masters. 410 626

Demonic Mosquito Poison Tide

Yu Chenglong's Third Soul Skill, acquired from the 2,500-year Myriad Phenomena Poison Devouring Demonic Mosquito. 662

• Releases waves of demonic mosquitoes to surround and poison enemies. 724
• The skill is also referred to as Magic Mosquito Swarm when deployed in battle. 724
• Nightmare can absorb Demon Tumor Poison Mosquitoes, swelling in size and strengthening before returning to Yu Chenglong's body. 665
• The mosquitoes absorb Soul Power, contributing to Yu Chenglong's cultivation after combat. 665
• Its viciousness can leave targets covered in venom and physically humiliated. 665
• Du Bai cautioned Yu Chenglong to use it carefully when unprotected, as its severity could invite retaliation from stronger factions. 665

Combat Style

Yu Chenglong specializes in long-range battlefield control, poison stacking, and exploiting his opponents' fear of humiliation. 36 598 600

• Uses toxic fog to dictate positioning, obstruct vision, and weaken enemies before they can engage him. 597 598
• Avoids direct confrontations with assault-type Soul Masters, recognizing that his role is control and interference rather than frontal offense. 598 651
• Maintains physical training and has studied daggers and other cold weapons to improve his ability to survive close combat. 36
• Achieved an 88-match winning streak in one-on-one Soul Fighting Arena battles. 598 599
• Defeated his cousins Yu Hongping and Yu Zhiyin by controlling them with poison mist before knocking each unconscious with a punch. 611
• Poisoned a Battle Soul King despite being only a Soul Elder, decisively proving Nightmare's combat value. 723 727

Equipment / Items
