Power Progression

Background and History

Jiang Yu dies in a plane crash after graduating from high school and transmigrates to Douluo Continent. At six, he recovers his previous-life memories while living as an injured beggar in Heaven Dou City; fragmented memories lead him to suspect that he crossed over in body as well as soul. An old beggar had raised him but died two months earlier. After three other beggars steal his food and nearly beat him to death, Jiang Yu persuades a delayed system to awaken the martial souls granted by its Xie Xie template. He kills his attackers in response to the system’s mission 1 2.

Red Dragon Douluo Wu Lie discovers Jiang Yu afterward and brings him to the Nine Treasure Glazed Tile Sect. Sect Master Ning Yunxiu gives him treatment, a home, and core-disciple status. She delays his first soul hunt for three months so that food, medicine, and conditioning can repair his neglected physique 3 4 5 8.

Jiang Yu later becomes a regular training companion to Ning Tian and Wu Feng. At seven and a half, he accepts Ning Yunxiu as his godmother. At ten, he travels with the two girls to Shrek Academy, where they enroll in New Student Class Nine 11 12 13 14 24.

His first year at Shrek brings him into conflict with Ma Xiaotao and the academy’s leadership after her uncontrolled Evil Fire endangers him and his companions. The resulting intervention by Illusion Douluo takes him to the Sea God Pavilion, where Mu En stimulates his hidden Space-Time Dragon bloodline. He later displays temporary martial-soul fusion during the freshman assessment and completes the sect’s Tide Transformation method, returning from his next soul hunt as a level-45 Soul Ancestor 27 28 29 30 33 46 49.

During the subsequent vacation, Jiang Yu absorbs the gold of life concealed within the Spirit-Devouring Carving Knife and uses his improved spatial abilities to enter the Ice and Fire Yin Yang Well. By fabricating a Dugu Family identity and demonstrating the divine aura within the Heart of Space, he obtains immortal herbs and other treasures. The herbs subsequently help him and Wu Feng transform their martial souls, with Jiang Yu permanently awakening the Space-Time Dragon 52 53 54 55 56 57 58 60 61.

After revealing his five-ring cultivation, Jiang Yu enters Shrek’s Inner Court and settles on Sea God Island. The Heart of Space later draws him into a divine inheritance realm, and his command of space and time continues to develop. At eleven, he becomes captain of the Shrek Seven Devils after Ma Xiaotao steps down and Dai Yueheng relinquishes the vice-captain position 65 67 71 74 78 86.

Appearance

Jiang Yu’s appearance changes markedly after the sect takes him in and again after his martial souls fuse 4 8 15 61.

• At six: Barely over a meter tall, painfully thin, pale, and marked by old and fresh injuries 1 4.
• After three months of care: Healthier complexion, broader shoulders, and a sturdier build 8.
• At ten: Nearly 1.8 meters tall, with sharply defined features and a balanced, strong-looking build 15.
• Temporary Space-Time Dragon manifestation: Smooth silver scales appear across his skin; during his controlled temporary fusion, the scales bear faint golden patterns and his presence becomes elusive and seemingly unbound by space 33 46.
• After absorbing the gold of life: His bearing becomes increasingly detached, calm, and unhurried 54.
• At eleven, after permanent fusion: Nearly 1.9 meters tall, with a slender, upright figure. His formerly black hair and eyes become pure silver with a crystal-like quality 61.
• Inner Court attire: Wears the Inner Court’s conspicuous red uniform 69.

Personality

Jiang Yu is pragmatic about survival and protective of opportunities to grow stronger. His years as a beggar taught him to plan ahead; even after learning that his paired martial souls impose an unusual cultivation restriction, he worries about whether the sect will still invest in him. He nevertheless accepts dangerous soul-ring hunts rather than settle for slower progress 1 10 11.

He trains relentlessly, sometimes preferring practice to leisure. Around familiar companions, he has a teasing sense of humor, particularly with Wu Feng. His bond with Ning Yunxiu and the Nine Treasures Trio gradually eases the isolation of his early life 12 13 19.

Ning Yunxiu distinguishes between his outward warmth and an underlying detachment shaped by childhood hunger, illness, and insecurity. He treats friends and enemies very differently: he jokes with companions and responds to their emotions, but shows exceptional ruthlessness toward opponents. Ning Tian recognizes this contrast, while Zhang Lexuan is disturbed when he discusses the possible extermination of the White Tiger Duke’s lineage as a way to eliminate an irreconcilable future threat 51 67.

His pragmatism includes deception and calculated restraint. At the Ice and Fire Yin Yang Well, he invents a family history and uses knowledge from his previous life to persuade its guardians. Conversely, he abandons the idea of attacking Huo Yuhao in the Far North after concluding that the Sky Dream Ice Silkworm and Ice Empress make the attempt overwhelmingly dangerous 52 55 56.

Jiang Yu acknowledges that his romantic affection is not limited to one person. He recognizes Ning Tian’s growing feelings without actively initiating or rejecting them, while admitting that he also wants more than friendship with her. His later interactions with Wu Ming and Han Ruoruo retain the playful, provocative manner he uses with close companions 50 78 86 91.

Abilities and Skills

Light Dragon Dagger and Shadow Dragon Dagger

Jiang Yu’s original two dragon-aura tool martial souls are an instance of Attribute Separation: different attributes expressed through a shared source. They later fuse permanently into the Space-Time Dragon 2 5 61 65.

• He could wield both daggers simultaneously, and each could receive spirit rings 2 5.
• The Light Dragon Dagger gained light-purification power from the Dawnlight Dragon ring. Its documented skills include Light Dragon Blade, Light Dragon Chain Slash, and Light Dragon Thrust 11 22 45.
• The Shadow Dragon Dagger gained spatial cutting from the mutant Man Faced Demon Spider ring. Shadow Dragon Blade is subsequently identified as the counterpart that merges with Light Dragon Blade 11 84.
• Former cultivation limit: Adding a ring to only one dagger created an imbalance that blocked further cultivation. He had to add rings to both at each bottleneck before advancing 10.
• Temporary fusion: Before permanent unification, he could briefly combine the daggers’ origins to invoke the Space-Time Dragon, a process resembling a self-performed Martial Soul Fusion Skill. This early state was unstable and demanded experimentation 46.
• Permanent fusion: After the origins merge, he can no longer transform the Space-Time Dragon back into the Light and Shadow Twin Daggers. Their existing spirit rings and skills fuse along with the martial souls 83 84.

Speed and Dagger Combat

Jiang Yu initially fights as an agility-type soul master, relying on speed and unconventional attacks rather than meeting stronger combatants head-on 12.

• His attacks overwhelm Wu Feng in a friendly match 12.
• With Ning Tian’s support, he combines Light Dragon Blade and Light Dragon Thrust to leave a thousand-year Demon Lizard Dragon mortally wounded 22.
• Illusion Douluo assesses his early path as lying between power attack and agility attack: his rings come from well-rounded, powerful beasts rather than speed specialists, and his attributes exceed those of ordinary soul masters at the same level 28.
• During the freshman semifinal, his speed, physique, and flexible attacks allow him to dominate Dai Huabin, Zhu Lu, and Cui Yajie simultaneously before they resort to the Hell White Tiger 45.
• After permanent fusion, the Space-Time Dragon’s specialty is spatial and temporal manipulation rather than exceptional physical enhancement. Nevertheless, Jiang Yu’s accumulated conditioning, immortal herbs, gold of life, and three top-tier Soul Bones give him physical strength far beyond Dai Yueheng’s 83.

Hidden Dragon Power

Jiang Yu senses a mysterious power within himself after obtaining rings for both daggers. The Illusion Douluo confirms its presence but cannot initially identify it; she suspects a true-dragon connection. Jiang Yu recognizes the likely Space-Time Dragon bloodline and hopes the Heart of Space can help merge his martial souls 11 17.

Mu En’s pure light power later stimulates that bloodline directly. Jiang Yu’s martial-soul origin absorbs the energy, producing interwoven gold and silver light, silver scales, and observable distortions of both space and time. The first manifestation drains all his Soul Power and ends in collapse 33.

Jiang Yu understands the Space-Time Dragon as a dragon favored by time and space, also possessing considerable light power, which once served as the Dragon God’s shadow guard. After months of contemplating the Heart of Space, he learns to invoke it through temporary martial-soul fusion. Immortal-herb refinement with Wu Feng eventually completes the permanent transformation 33 46 60 61 65.

Space-Time Dragon

The fused Space-Time Dragon gives Jiang Yu a single martial soul centered on spatial and temporal manipulation. His earlier dagger skills combine into new techniques, while his understanding of the underlying laws continues to grow 78 83 84.

• Spatial Traversal / Space Transfer: Allows spatial movement and escape. Before permanent fusion, he already uses spatial abilities to bypass the Ice and Fire Yin Yang Well’s poisonous perimeter and depart instantly; later, his traversal astonishes Xuan Zi 55 57 74.
• Spatial phasing: During temporary fusion, he makes his body illusory and passes through Du Weilun’s Soul Power blockade 46.
• Spatial flight: By controlling surrounding Space Element, he can levitate and fly faster than a Class 4 Flying Soul Tool. Following his gold of life enhancement, its modest spiritual expenditure is lower than his recovery rate 54.
• Space-Time Blade: The fusion of Light Dragon Blade and Shadow Dragon Blade. Without a dagger martial soul to serve as its vessel, it is almost exclusively a ranged attack 84.
• Space-Time Eighteen Slashes: A multi-strike technique used against Dai Yueheng in combination with his domain 85.
• Space-Time Dragon Domain: His fourth Soul Skill. It applies spatial suppression, time acceleration, and rewinding effects, helping more than half of his Space-Time Eighteen Slashes strike Dai Yueheng 85.
• Developing temporal control: He initially believes that substantial mastery of space is a prerequisite for commanding time. By his Inner Court period, he has gained initial insight into temporal power, with the Time-Space Divine Crystal accelerating his progress 54 78.

Cultivation Methods and Physical Foundation

• Sect foundation-building method: Produces a Soul Power Vortex. The light and life energy absorbed at the Sea God Pavilion brings that vortex into its final form 34.
• Soul Power Vortex Tide Transformation: Completed during an extended seclusion at the Nine Treasure Pavilion. Together with two ten-thousand-year rings, it raises him to level 45 and gives him Soul Power quality and reserves surpassing an ordinary high-level Soul King 49.
• Exceptional spiritual foundation: His two lives give him an unusually powerful soul and strong comprehension. Illusion Douluo identifies his Spiritual Power and Sea of Consciousness as extraordinary even at six 11 54.
• Gold of life enhancement: Expands his Sea of Consciousness to at least three times its previous size and creates a life-filled lake within it. He estimates that his spiritual growth and recovery become at least three times faster 53.
• Physical resilience: After absorbing the gold of life, his body is comparable to an ordinary Soul Sage or Soul Douluo and can withstand two high-quality rings older than fifty thousand years at his next bottleneck 53.
• Spiritual regeneration: The gold of life continuously nourishes his Sea of Consciousness. Jiang Yu concludes that it can repair even severe damage provided the entire sea is not utterly destroyed 53.

Divine Inheritance

The Heart of Space first enables Jiang Yu to display a genuine divine aura at the Ice and Fire Yin Yang Well, persuading its guardians that he is a god’s heir. Later, it pierces his brow and transports his spiritual form to a Silver Palace associated with the Space God’s inheritance 56 71 74.

• He can sense the unusual spatial laws within the inheritance realm despite being only a Soul King 71.
• The Space God’s Divine Nature Seed adds a silver divine quality to his Soul Power 74.
• The Time-Space Divine Crystal supports near-daily advances in his understanding of space and time after his return from the Divine Realm 78.

Equipment and Items

• Storage Soul Tool — Given to him by Ning Yunxiu 7.
• Core-disciple uniform and token — Prepared upon his admission to the sect 7.
• Crimson Spirit Warm Jade pendant — A birthday gift from Ning Tian that provides warmth, communication, and emergency protection. He later uses it to maintain lengthy evening conversations with Ning Tian and Wu Feng while living in the Inner Court 14 67 69.
• Century Fire Lotus — A birthday gift from Wu Lie, intended to purify Soul Power and nourish the body 14.
• Soul-Destroying Cannon — A level-eight Soul Tool Ning Yunxiu buys at his request for last-resort protection; its recoil requires a strong body. Three precharged Energy-Storage Arrays allow it to deliver either a Titled Douluo-level strike using one array or a level-95 Super Douluo-level strike using all three. He deploys it against the rampaging Ma Xiaotao and suffers internal injuries during the encounter 16 28 29.
• Heart of Space — A relic Ning Yunxiu buys after it resonates with Jiang Yu’s hidden power. Its mental and spatial energy resist the Illusion Douluo’s examination. Jiang Yu later discovers that it increases his Space Spirit Right Leg Bone’s age by approximately one hundred years overnight, studies spatial power through it, and uses its divine aura to intimidate the immortal herbs. It eventually activates the Space God’s inheritance 17 21 35 46 56 71.
• Space Spirit Right Leg Bone — An evolving Soul Bone acquired during his early visit to the Sea God Pavilion. Its age increases under the Heart of Space’s influence; Jiang Yu estimates that sustained growth at the observed rate could bring it to one hundred thousand years in under three years 34 35.
• Space-Binding Thorn Right Leg Bone — Sought to merge with his existing right leg bone and obtain a hundred-thousand-year bone before his duel with Dai Yueheng 82 83.
• Blade of Life / Gold of Life — Originally the Spirit-Devouring Carving Knife, purchased through a sect agent. Wu Lie purifies its evil energy, exposing the gold of life within, and Jiang Yu renames it the Blade of Life before absorbing its power through his brow 52 53.
• Immortal herbs and medicinal treasures — Acquired from the Ice and Fire Yin Yang Well through negotiation, deception, and intimidation. His haul includes an Aromatic Silk Beauty, singular velvet sky chrysanthemum, cockscomb phoenix sunflower, and earth dragon golden melon. He shares the herbs’ benefits with his companions and uses them in the cultivation that completes his martial-soul fusion 57 58 60.
• Thunderclap Hellvine — Obtained from the Ice and Fire Yin Yang Well as a prospective source for his fifth ring 57.
• Ultimate Thunder Left Leg Bone — A blue-violet, lightning-covered Soul Bone acquired after absorbing his lightning-wreathed ten-thousand-year ring 64.
• Time-Space Divine Crystal — A divine cultivation aid that enters his brow and helps develop his understanding of space and time. Its glow has changed from deep blue to pure silver by the morning after his inheritance experience 74 78.

Relationships

• Ning Yunxiu — Sect master who takes Jiang Yu in and later becomes his godmother; he calls her “Mom” by age ten. She understands the sharp contrast between his treatment of friends and enemies and discusses his developing relationship with Ning Tian. His acquisition of the Aromatic Silk Beauty brings the sect a treasure it has sought for ten thousand years 4 13 15 51 58.
• Wu Lie — The Red Dragon Douluo who finds him, protects him, and guides his early soul hunts. Jiang Yu calls him “Grandpa Wu.” Wu Lie later purifies the Spirit-Devouring Carving Knife so Jiang Yu can absorb its gold of life 3 8 10 11 53.
• Ning Tian — Close training companion and member of the Nine Treasures Trio. They support one another in combat and enroll at Shrek together. Their friendship develops mutual romantic undertones, which Jiang Yu recognizes and does not reject. During the freshman assessment, she chooses to team with Wu Feng and Nanmen Yun’er rather than rely on him 12 14 22 24 39 50.
• Wu Feng — Fellow trio member and frequent sparring partner. Their early friction develops into familiar, mostly harmless bickering. She offers to wear a maid outfit for five days if he kills or cripples Dai Huabin and Zhu Lu in the semifinals, and he agrees. Their later coordinated immortal-herb refinement helps fuse his martial souls while his draconic power contributes to her transformation into the Crimson Radiance Dragon 12 13 19 44 60 61.
• Lu Yaoyao — Food-type Soul Sage who oversees his three-month nutritional regimen 7 8.
• The old beggar — His adoptive grandfather, who raised and named him; his death leaves Jiang Yu alone on the streets 1 4.
• Xie Huanyue — Shrek dormitory roommate whom Jiang Yu befriends and considers a potential sect recruit 25.
• Illusion Douluo — Sect elder who examines his hidden power and the Heart of Space. She intervenes against both the Blue Lightning Tyrant Dragon Clan’s demands and Shrek’s treatment of the trio, and later recognizes that his martial souls are nearing fusion 11 19 21 30 60.
• Mu Jin — His Class Nine teacher and later lead homeroom teacher in first-year Class Two. Their arrangement lets Jiang Yu train independently instead of attending every class; Mu Jin also approves the extended leave needed for his Tide Transformation seclusion 27 49.
• Mu En — Recognizes the unusual dragon origin behind Jiang Yu’s daggers and uses pure light power to stimulate it, producing his first visible Space-Time Dragon manifestation. Jiang Yu subsequently visits him after discovering the divine quality in his Soul Power 33 74.
• Ghost Blade Douluo — Guards his Tide Transformation seclusion and accompanies him to obtain the rings that raise him to Soul Ancestor 49.
• Tang Xingxing and Tang Yueyue — Support-type freshman assessment teammates whose Seven-Colored Rings enhance his attributes. They withdraw from the semifinal arena after supporting him so he can fight freely 40 45.
• Zhang Lexuan — Inner Court senior sister who treats his injuries with Clear Spirit Pills and listens to the trio’s account without defending Yan Shaozhe. She later helps him settle into the Inner Court, warns him about Dai Yueheng, and is troubled by his willingness to contemplate destroying the White Tiger Duke’s lineage 30 65 67 78.
• Wu Ming — Guides him around the Inner Court for three days and develops an openly affectionate manner toward him. She serves him food, holds his hand with interlocked fingers, and intervenes when Ma Xiaotao and Dai Yueheng confront him 69 78 81 86.
• Han Ruoruo — Inner Court senior who befriends him while remaining suspicious of his intentions toward Wu Ming. Despite those doubts, she protects him from senior students’ intimidation. Their familiarity later develops into teasing exchanges, including her and Wu Ming restraining him with the Shaking Gold Rope 78 81 91.
• Ma Xiaotao — Her Evil Fire rampage endangers Jiang Yu, Ning Tian, and Wu Feng, prompting his cannon retaliation and the sect’s demand for redress. When she later questions his compensation claim, he condemns her refusal to accept responsibility. She eventually steps down as Shrek Seven Devils captain in his favor 27 28 30 81 86.
• Dai Huabin and Zhu Lu — Freshman rivals whose confrontation with him escalates from the dining hall to the assessment semifinals. Jiang Yu wounds Zhu Lu, later severs three fingers from her right hand, and disfigures Dai Huabin, creating an enduring feud with the White Tiger Duke’s Mansion 44 45 46 67.
• Dai Yueheng — Dai Huabin’s elder brother and an Inner Court Soul Emperor. Their hostility culminates in a duel in which Jiang Yu’s fused skills and domain leave him gravely wounded. Dai Yueheng later relinquishes his vice-captain position in the Shrek Seven Devils 67 81 82 84 85 86.
• Huo Yuhao — Jiang Yu regards him as both a useful early distraction and a potential future opponent because of Tang San’s control over his fate. He rejects an excessively risky Far North attack and later warns Ning Tian and Wu Feng about Huo Yuhao’s Ice Jade Emperor Scorpion martial soul. Huo Yuhao, meanwhile, blames Jiang Yu and his companions for Zhou Yi’s loss of her teaching post 23 49 52 86.
• Youyou and Jiaojiao — Intelligent immortal herbs at the Ice and Fire Yin Yang Well. He deceives Youyou with a fabricated Dugu Family identity and clashes with Jiaojiao over the promised treasures, ultimately using the Heart of Space’s divine aura to improve his bargaining position 55 56 57.
