Power Progression

Appearance

Deng Jilin is a handsome man in his thirties with long ice-blue hair, a cold temperament, and faintly arrogant brows. In battle, he commonly wears white and carries his Sky Cold Sword, surrounded by drifting chill that gives him an ethereal presence 35 118.

• Long ice-blue hair 35
• Cold, rigid demeanor 35 36
• White clothing and a sword-bearing combat stance 118
• Ice-cold Soul Power aura 38 61
• Ice-blue eyes 58
• Wears the uniform of a Heaven Dou Grade Special Teacher while serving at the academy 61
• After obtaining his eighth Soul Ring, demonstrates Winter's Arrival while standing atop an ice dragon with the Heavenly Frost Sword in hand 164

Personality

Deng Jilin is taciturn, straightforward, and governed by firm personal principles. He dislikes empty conversation, often responding with only a few words, but his silence does not reflect indifference; he is dependable in both administrative tasks and dangerous confrontations 35 36 69.

He regards Su Ge's prior aid as a debt that must be repaid. Even after Su Ge repeatedly tells him not to dwell on it, Deng remains determined to assist him because Su Ge's help saved his life and enabled his advancement 35.

Though cold toward opponents, Deng shows compassion for people forced into conflict. When two Soul Saints admit they were coerced into attacking him, he directs his anger toward the mastermind rather than treating them as simple enemies 118.

His pride and seriousness make the deaths of worthy opponents particularly troubling to him. After killing the coerced Lin Family Head and Dean Zhang, he sits silently before their frozen remains and asks when Su Ge intends to attack the Clear Sky Sect. His unresolved sense of injustice subsequently unsettles his domain control and obstructs his advancement, despite successfully condensing an Ultimate Ice Soul Core 124 129 130.

Deng also displays a quieter sense of humor among companions, teasing Yu Tianheng with Su Ge's “vertical line” metaphor. His trust in Su Ge does not eliminate his caution: he warns him about unfamiliar Martial Souls, traps, and assassination methods even while acknowledging his overwhelming combat strength 115 117.

During the Far North expedition, Deng willingly challenges a hundred-thousand-year Soul Beast to temper himself, but recognizes when the disparity in strength requires withdrawal. He respects Su Ge's silence about private concerns and acts immediately when asked to assist with the Sky Dream Ice Silkworm's sacrifice 163 170.

“I, Deng Jilin, have always had clear principles. I helped you because you helped me.” 35

Abilities & Skills

Sky Cold Sword

Deng Jilin's martial soul is an ice-attributed sword noted for its sharpness and exceptionally pure cold power 73 78.

• Produces ice-attributed Soul Power capable of suppressing opponents 61.
• Its ice power is described as purer than Shui Bing'er's Ice Phoenix during the inter-academy friendly match 115.
• Was initially considered capable of evolving toward Ultimate Ice as its ice element strengthened; he later demonstrates Ultimate Ice in battle 78 119.
• His martial soul's potential was enhanced by the Frostleaf Swordheart Grass 74.
• Later passages refer to the weapon as the Heavenly Frost Sword 119 164.
• Can release supremely frigid sword energy that spreads frost and icy mist along its path 151.
• His ice power is particularly well suited to the Far North, where the environment strengthens his abilities and helps temper his cultivation 162 163 165.

Self-Created Ice Techniques

Deng can employ swift, unconventional ice techniques without visibly revealing Soul Rings 38.

• Instantly encases Flender in an ice coffin, leaving him unable to react 38.
• Places a chilling blade at Flender's shoulder immediately after immobilizing him 38.
• Condenses icy chains that bind Qin Ming and seal his Soul Power 63.
• Forms a Soul Power barrier to prevent a private conversation with Su Ge from being overheard 158.

Sky Cold Domain

Deng began comprehending an ice-based domain while meditating at an academy ice lake 73.

• Its initial manifestation fills the area with freezing wind, snow, ice, and sword-like chill 73.
• Unlike an innate or Soul Ring-granted domain, it can continuously strengthen through deeper insight 73.
• Frostleaf Swordheart Grass may aid his domain comprehension and grant Sword Heart Clarity 74.

The developed domain is called the Heavenly Frost Domain. When released outside Silves City, it transforms the surroundings into a frozen landscape resembling the Far North. Its Ultimate Ice allows Deng's frosty sword energy to freeze Dean Zhang's fiery crescent attack outright, after which the remaining force badly injures the opposing Soul Saint 119.

• Draws upon surrounding wind and snow to support combat and attempt to suppress an opponent's strength 129.
• Requires a composed state of mind for effective control; Deng's resentment after his breakthrough weakens his use of the domain 129 130.
• Is overwhelmed by Su Ge's evolved Domination Domain during their training session 129 130.
• Later spreads biting cold across the Pope's Palace plaza and overpowers Yu Luomian's thunder-based attack 152.

Soul Core Research

Deng studies Su Ge's Soul Core hypothesis with Dugu Bo, using Dugu Bo's Pill Pearl as a possible model for compressing Soul Power from liquid into solid form 89.

• Seeks to develop a more advanced cultivation method rather than relying solely on ordinary Soul Power accumulation 89.
• His talent as a Soul Saint in his thirties makes him a suitable candidate for the research 89.
• Pursues an Ultimate Ice Soul Core corresponding to his martial soul's attribute 125.
• Successfully condenses the Ultimate Ice Soul Core before overcoming his level-79 bottleneck 130.
• Travels to the Far North partly because Su Ge believes a true world of ice and snow is needed to perfect his Soul Core and sword intent 158.

Sword Heart and Sword Intent

Deng's cultivation emphasizes an exquisite heart of sword intent and keeping his thoughts clear and unburdened. This pursuit of clarity supports his growth, but unresolved resentment can also become a cultivation obstacle 130 152.

Su Ge advises him to confront injustice directly and use the sword to break deadlocks rather than allowing inner turmoil to wear him down. After their discussion, Deng's eyes regain some clarity, though his emotional conflict is not immediately resolved 130.

Soul Ring Skills

Following Su Ge's suggestion, Deng uses Winter's Arrival to form an ice dragon and ride atop its head. At level 85, he can condense up to eight dragons to assist him in battle; he expects to control nine after reaching Titled Douluo 164.

Both eighth-ring skills have adjustable output, allowing them to function as ordinary combat techniques or stronger bursts of power. Su Ge also identifies the possibility of concealing Soul Slash attacks among conventional sword-energy strikes 164.

Soul Bone Skills

The hundred-thousand-year Soul-Splitting Ice Bear King grants Deng a left-arm Soul Bone with two spirit-targeting abilities 164 165 170.

These skills provide Su Ge with a means of managing the Sky Dream Ice Silkworm's immense spiritual power and safeguarding against interference with his memories. Their use during the sacrifice nearly exhausts Deng's Soul Power; his advancement to Soul Douluo is essential to completing the division and sealing 165 169 170.

Combat Strength and Limitations

• As a level-78 Soul Saint, possesses enough domain-enhanced power for the Lin Family Head to compare him with an ordinary Soul Douluo 119.
• After reaching the level-80 threshold but before obtaining his eighth ring, forces the level-89 Yu Luomian back and later gravely wounds him with domain-supported sword energy 151 152.
• Can fight and wear down a hundred-thousand-year Soul-Splitting Ice Bear King while at level 80, but cannot bridge the full disparity in power; the duel considerably depletes his strength 163.
• After advancing to level 85, is assessed by Su Ge as potentially stronger than an ordinary Titled Douluo 164.
• Withstands the Sky Dream Ice Silkworm's spiritual assault alongside Su Ge and forces the creature to cease attacking with a sword threat 168.

Equipment / Items

• Storage Soul Guidance Device — Used to transport seven high-quality pieces of Whale Glue and later store instructions for collecting the Morningstar Reflection Flower 35 101.
• Frostleaf Swordheart Grass — Immortal Herb gifted by Su Ge; strengthens and condenses his Soul Power while improving the Sky Cold Sword's potential 74.
• Two additional suitable Soul Bones — Absorbed before the Far North expedition. Su Ge states that they have strengthened Deng's body enough to attempt absorbing a hundred-thousand-year eighth Soul Ring; their types are not specified in that discussion 158.
• Soul-Splitting Ice Bear King Left-Arm Soul Bone — Obtained with his eighth Soul Ring; grants Soul Split and Soul Seal 164 165 170.
• Ten-Thousand-Year Ice Marrow — Uses a piece to recover his Soul Power after dividing and sealing the Sky Dream Ice Silkworm's spiritual origin 170.

Relationships

• Su Ge — Benefactor, close friend, and trusted leader. Deng considers Su Ge responsible for saving his life and aiding his seventh-ring hunt; he later serves as an enforcer, messenger, administrator, and protector within Su Ge's growing faction 35 67 101. Su Ge helps him confront his emotional bottleneck, accompanies him to obtain a hundred-thousand-year eighth ring, and entrusts him with controlling the spiritual energy of a million-year sacrifice 130 158 163 170.
• Imperial Fighting Team — Their Special Teacher and acting leader during Su Ge's absences. He negotiates matches, selects battle lineups, and takes responsibility for their protection 80 115 118.
• Ning Rongrong — Acquainted through Su Ge. Deng remains largely indifferent to her conversations but helps escort her to Heaven Dou City and works alongside her in protecting the Imperial Fighting Team 36 52 118.
• Dugu Bo — Consults him regarding the Soul Core hypothesis; Dugu Bo also protects the Imperial Fighting Team's hotel while Deng draws attackers away 89 118.
• Yang Wudi — Personally contacts and escorts the Breaking Clan head to meet Su Ge, then later relays Yang's refusal to cooperate with Tai Tan 69 101.
• Flender — Delivers Su Ge's warning to him and demonstrates enough speed and ice-based control to immobilize the Soul Saint before Flender can respond 38.
• Qin Ming — Subdues him during Su Ge's takeover of the Imperial Dou Team, suppressing his Soul Power and holding the Sky Cold Sword at his neck 61 63.
• Yu Tianheng — Guides him as a team teacher and gives him a blunt assessment of the gap between his strength and Su Ge's, mixing teasing with genuine instruction 115.
• Lin Family Head and Dean Zhang — Coerced opponents whom Deng comes to respect. Though he kills them in battle, their predicament leaves him resentful toward the people responsible and determined to seek justice 118 124 152.
• Clear Sky Sect — Identified by Su Ge as the force behind the Silves City operation. Deng asks when Su Ge will attack the sect and later regards its renewed encirclement as an injustice to be answered with his sword 124 152.
• Yu Luomian — Intercepts Deng during the attack before the Pope's Palace. Deng counters his thunder-based attacks with the Heavenly Frost Domain and gravely wounds him 149 151 152.
• Sky Dream Ice Silkworm — Initially treats the creature as a potential enemy when it refuses Su Ge's offer. After negotiations succeed, Deng supports its sacrifice by dividing and sealing its spiritual origin within Su Ge 168 169 170.

Story Role / Major Arcs

Aid to Su Ge

Deng first meets Su Ge in Suotuo City after procuring seven pieces of high-quality Whale Glue. He reveals that Su Ge's information and self-created-skill ideas were instrumental in his successful seventh-ring hunt, which raised him to level 72 35.

He agrees to remain by Su Ge's side and soon acts on Su Ge's behalf, confronting Flender with a warning and demonstrating his ability to incapacitate another Soul Saint 36 38.

Heaven Dou Royal Academy

Deng escorts Ning Rongrong and Zhu Zhuqing to Heaven Dou City while Su Ge pursues his fifth Soul Ring. At the academy, he serves as a Grade Special Teacher and supports Su Ge's assumption of control over the Imperial Dou Team 52 61.

He suppresses Qin Ming, assists Su Ge in confronting the team, contacts Yang Wudi of the Breaking Clan, and arranges Xiao Chenyu's family transfer on Su Ge's instructions 61 69.

Because of his Soul Saint cultivation, Deng has relatively few teaching duties, mainly specialized lessons. This leaves him substantial time to cultivate at the ice lake atop the academy mountain 73.

Cultivation and Faction Administration

While cultivating at the academy's ice lake, Deng begins forming the embryonic Sky Cold Domain. Su Ge rewards his loyalty with Frostleaf Swordheart Grass, an Immortal Herb tailored to his martial soul and domain path 73 74.

Deng later manages reports on the medicinal-cuisine program, communicates with the Breaking and Ye Clans, and accepts responsibility for retrieving the Morningstar Reflection Flower for Ye Tianxin 101.

He also undertakes a mission to Holy Soul Village. On returning, he delivers the living Blue Silver Emperor and its hundred-thousand-year Soul Bone to Su Ge, contributing to Su Ge's effort to deprive Tang San of future cultivation opportunities 111 114.

After the Silves City incident, Deng pursues the formation of an Ultimate Ice Soul Core. Although he succeeds, resentment over the coerced attackers prevents his advancement beyond level 79 and weakens his domain control. Su Ge advises him to sever this emotional deadlock through his own resolve. By the tournament period, his aura has reached the level-80 threshold, though he still possesses only seven rings 125 129 130 133.

Imperial Fighting Team Tour

As the Imperial Fighting Team's leader, Deng negotiates with Silves City's major powers and the Great Soul Arena to secure strong Soul Ancestor opponents and rewards for the team's tour 116.

When two Soul Saints target the team near their Silves City hotel, he orders the students inside, draws the attackers beyond the city, and chooses to face both alone. Learning that the Lin Family Head and Dean Zhang were coerced, he vows to hunt down the person who forced them into the attack 118.

Deng counters the Lin Family Head's stone-armored fists with an ice greatsword, then releases the Heavenly Frost Domain against Dean Zhang's fire attack. His Ultimate Ice freezes the fiery crescent, and his follow-up sword energy sends Dean more than a hundred meters away, badly injured 119.

He realizes that the two opponents are attempting to stall rather than defeat him. They admit that their orders are to keep him occupied, revealing that the confrontation is part of a larger operation. Deng remains confident that any force targeting Su Ge has badly misjudged his strength 119 120.

When Su Ge returns, he finds Deng sitting before the frozen remains of both opponents. Deng learns that the separate ambush against Su Ge came from the Clear Sky Sect and asks when Su Ge intends to attack it. Su Ge answers that it will be after the Soul Master Tournament 124.

Soul Master Tournament and Pope's Palace Conflict

Deng supports the team during the tournament and reassures Meng Shenji that Su Ge can handle the consequences of its confrontations 133.

When Tang Hao and two Clear Sky Sect elders move against Su Ge before the Pope's Palace, Deng immediately attempts to intervene. Yu Luomian intercepts him with more than twenty fighters, preventing him from reaching the three Titled Douluo. Xiao Wu, Zhu Zhuqing, Ning Rongrong, and Ye Lingling remain to fight alongside him while the uninvolved students are escorted away 149.

Despite having only recently reached the level-80 threshold, Deng drives the level-89 Yu Luomian back. He activates the Heavenly Frost Domain, overpowers the opposing thunder attack, and gravely wounds Yu Luomian with icy sword energy before turning on his Shadow Guards 151 152.

When Spirit Hall subsequently attempts to arrest the participants, Su Ge takes Yu Xiaogang hostage and orders his allies to leave under Sword Douluo and Bone Douluo's protection. Deng departs immediately, prompting the others to follow and helping Su Ge secure their withdrawal before continuing negotiations 155.

Far North Expedition

After the tournament, Deng accompanies Su Ge to the Far North. Their goals include obtaining his eighth Soul Ring from a suitable hundred-thousand-year Soul Beast and perfecting his Soul Core and sword intent through cultivation in a true frozen environment. Su Ge considers Deng's body sufficiently prepared after the absorption of two suitable Soul Bones 158.

The pair gather information at Cold Gate Pass and head deeper into the north. Deng's presence becomes more solid through the journey, and Su Ge selects the bear gathering grounds as a more promising destination than the Icefield Wolf territory 159 162.

Nearly half a year into their expedition, Deng challenges a hundred-thousand-year Soul-Splitting Ice Bear King while Su Ge holds back the surrounding bears. Deng inflicts numerous cuts but cannot seriously injure the king, and his strength steadily declines. When two stronger kings approach, he withdraws and asks Su Ge to finish the encounter quickly 163.

Su Ge leaves the Ice Bear King near death, carries it to their hidden cave, and stands guard while Deng recovers and prepares to absorb its ring. The Soul Ring and Soul Bone absorption proceeds smoothly, raising Deng to level 85 and granting Soul Slash, Winter's Arrival, Soul Split, and Soul Seal 163 164.

At Su Ge's suggestion, Deng demonstrates Winter's Arrival by forming an ice dragon. His soul-targeting Soul Bone skills then give Su Ge a possible solution to the danger posed by the Sky Dream Ice Silkworm's immense spiritual power. Deng agrees to consolidate his cultivation and train the skills for their later use 164 165.

Sky Dream Ice Silkworm's Sacrifice

During their search for ice marrow, Deng detects a hard ice formation with energy flowing beneath it and identifies a likely high-quality vein. He stands guard while Su Ge melts a passage into the underground cavern, then joins him in searching its depths 166 167.

The pair find the Sky Dream Ice Silkworm feeding on ice marrow. Deng instinctively shields Su Ge when the creature unleashes an intimidating aura, while Su Ge recognizes its display as Simulation and begins negotiating for its sacrifice 167.

When the Silkworm refuses, Deng suggests killing it. After it attacks with spiritual power, he and Su Ge withstand the assault, and Deng drives his sword into the ground beside the creature and threatens to kill it if it attacks again. He subsequently remains watchful as Su Ge offers the possibility of godhood and immortality 168.

Once the Silkworm agrees and reaches one million years, Deng supports Su Ge's absorption and serves as a safeguard against interference with his memories. As the incoming energy pushes Su Ge's body and abilities to their limits, Deng acts on his instructions, using Soul Split to divide the remaining spiritual origin into hundred-thousand-year-equivalent portions and Soul Seal to store seven portions in Su Ge's Sea of Consciousness 169 170.

The effort leaves Deng almost completely exhausted. After completing the task, he rests beside the ten-thousand-year ice marrow and uses a piece to replenish his Soul Power while Su Ge finishes absorbing the million-year sacrifice 170.

Trivia

• Deng's favorite terse response is “Fine,” which frustrates Su Ge during their conversations 36.
• He later adopts Su Ge's “vertical line” metaphor to humorously explain the vast difference between Yu Tianheng and Su Ge 115.
• Despite his own exceptional talent, Deng concludes that even his perfected domain would likely not let him withstand a single punch from Su Ge 101.
• Su Ge's suggestion that Winter's Arrival form ice dragons is partly inspired by his desire to recreate the spectacle of Mystic Ice Dragon Soar, though he also recognizes its practical value in group battles 164.
• Deng and Su Ge cook and eat the hundred-thousand-year Soul-Splitting Ice Bear King's meat after the successful absorption 165.
• The exertion of dividing and sealing the Sky Dream Ice Silkworm's spiritual origin makes him slump to the ground without his usual dignity before recovering with ice marrow 170.
