Background

Lin En arrives on the Douluo Continent after being transported from another world by an incident involving a monitor. Village chief Lao Jierui finds and raises him in Emperor Soul Village. He recovers his previous-life memories early and discovers that Tang San lives in neighboring Holy Soul Village, confirming that they belong to the same era 1.

Before awakening his martial souls, he exercises regularly for six years to improve his chances of becoming a Soul Master. His original ambition is a comfortable life rather than godhood, but awakening two powerful external martial souls radically changes his expectations 1.

Appearance

  • At Nuoding graduation: Stands 1.6 meters tall, with broad shoulders, a powerful waist, and a sharp, intimidating presence 12.
  • Facial features: Has a jade-like complexion, slender brows, and tousled, choppy hair 43.
  • Skywater uniform: Wears a custom aqua-blue, trench-coat-like uniform with upturned tails and blue-and-gold collar detailing 43.
  • After spring refinement: Deep-blue and dark-red patterns appear on his skin. His evolved spider lances divide into matching ice-and-flame colors 86.
  • Eyes: Normally deep black; briefly turn icy blue after absorbing the Dragon Kings’ Soul Bones 91.

Personality

Lin En combines a pleasure-seeking outlook with strong survival instincts. Although he complains about cultivation and dreams of an easy life surrounded by beautiful women, he trains consistently when he recognizes that strength is necessary to protect himself. He hides his transmigration, second martial soul, and early cultivation achievements to avoid dangerous attention 1 4 8 12.

He is openly mercenary. He charges for protection and training, repeatedly extorts Zhu Zhuqing and her pursuers, and demands two million Gold Soul Coins for protecting Ning Rongrong. He describes himself as an “honest scoundrel” rather than a hypocritical gentleman and makes little effort to appear conventionally virtuous 14 16 24 56.

His provocative humor frequently becomes deliberate humiliation. He enjoys enraging opponents who cannot retaliate effectively, targets Yu Xiaogang’s authority, and mocks Dai Mubai’s treatment of women. His flirting also includes taking liberties under the pretext of examinations, earning him a notorious reputation at Skywater Academy 10 20 48 77 79.

Despite his frivolity, he is dependable in dangerous situations. He develops sustained training plans for Sageross, intervenes when Zhu Zhuqing misjudges an opponent, and endures painful Soul Bone absorptions rather than abandoning them. He also rejects the idea that he should conceal either his serious or frivolous side merely to satisfy others 10 18 27 33 36.

Abilities & Skills

Twin External Martial Souls

Sageross and Ingkaros manifest outside Lin En’s body and fight under his commands 4 36.

  • Separate ring sets: Switching from Sageross to Ingkaros makes his first ring disappear, confirming that the two martial souls do not share ring slots 7.
  • Mutual growth: Lin En and Sageross reinforce one another’s advancement; improvement in either feeds back into the other 7.
  • Over-limit ring absorption: Sageross takes in the most savage energy first, reducing the burden Lin En must absorb himself 6 12.
  • Independent skill development: Sageross unlocks abilities beyond those supplied by Soul Rings as he grows stronger 12.
  • Coordinated combat: The two mantises defeat the ten-thousand-year Blade Thornspine Dragon through sustained alternating attacks 36.
  • Shared enhancement benefits: Ning Rongrong’s strength and speed boosts affect Sageross as well as Lin En 55.

Sageross

Sageross is Lin En’s principal combat martial soul, specializing in scythe attacks, dark energy, and mobile assault 1 12 79 80.

Soul Ring Age / Source Documented Skill Effect
First 800-year Ghost Tiger Shadow Clone Produces four indistinguishable duplicates alongside the original. A duplicate dissipates when struck 6 7.
Second 2,000-year ring; beast unspecified Darkness Power Compresses dark energy along Sageross’s blades. Lin En can apply a second layer for a stronger attack 12 55.
Third 5,000-year ring; beast unspecified Blade Storm Unleashes a large-scale blade attack; used against the Blade Thornspine Dragon and the Dragon-Tiger Combination 12 28 36.
Fourth 10,000-year Blade Thornspine Dragon Blade Light River Identified as his fourth Soul Skill; the supplied passage does not detail its execution 36 55.

Other documented techniques include:

  • Rage Enhancement: Creates a dark-purple force field and strengthens Sageross’s attacks 6.
  • Blade Assault: Channels dark-purple power through his blades for a close-range assault 6.
  • Tackle: Used to exploit exposed areas, including the Ghost Tiger’s belly 6.

  • Tooth-Linked Assault: Launches repeated crescent blades to bombard an enemy formation 80.
  • Flight and transport: Develops crystalline wing blades and carries Lin En and Zhu Zhuqing through the air 13 18.
  • Deterrence: His aura drives weaker Soul Beasts away during Skywater’s forest expedition 47.

Ingkaros

Ingkaros is Lin En’s concealed second external martial soul 1 4 7.

  • Defensive reserve: Lin En initially keeps him hidden as protection against ambush while Sageross is away 4.
  • Vacuum Thousand-Strikes Break: Used alongside Sageross’s Blade Storm against the Blade Thornspine Dragon 36.
  • Limited exposure: The supplied passages document far fewer of Ingkaros’s techniques than Sageross’s.

Eight Spider Lances

The Eight Spider Lances are a controllable external Soul Bone acquired from a thousand-year Man Faced Demon Spider 18.

  • Structure: Eight retractable, purplish-black legs emerge beside his spine, extending over three meters and tapering to sharp points 18.
  • Offense and restraint: Used to strike opponents, hold targets at lance-point, and manipulate heavy obstacles 35 81.
  • Defense: Form a skeletal shield capable of blocking Yu Tianheng’s lightning without visible damage 80.
  • Venom: Inject Man Faced Demon Spider venom, rapidly rendering Yu Tianheng unconscious 81.
  • Evolution: Become the Iceflame Eight Spider Lances after spring refinement, with four deep-blue lances on one side and four dark-red lances on the other 86.
  • Further development planned: Lin En selects a seventy-thousand-year Purple Intent Spider Emperor to devour and fuse into the lances rather than absorb its ring; completion is not shown 91.

Life Force and Meridian Treatment

Lin En uses the Blue Silver Emperor’s power to nourish bodies, straighten meridians, and open blocked vessels 70 71 75.

  • Cultivation assistance: Opens Lan Susu’s Thoroughfare Vessel, breaking her level-seventy-eight bottleneck and allowing her to reach level seventy-nine 75.
  • Physical refinement: Zhu Zhuqing reports improved flexibility, coordination, and bodily control after her meridians are opened 71.
  • Poison management: Forces Dugu Bo’s toxins into his Medusa Head Soul Bone and treats the associated backlash, stabilizing him for at least six months 88.
  • Dugu Yan’s treatment: Organizes her toxins and corrects her Soul Power circulation; a suitable Soul Bone is still necessary for long-term containment 88.
  • Limits: Treatment can exhaust his Soul Power and requires careful control. Increased proficiency later reduces the Thoroughfare Vessel procedure to approximately fifteen minutes 69 71 75.

Soul Bone and Body Enhancements

  • Blue Silver Emperor Right Leg Bone: Grants flight, widens his meridians, and substantially improves his strength, speed, and jumping ability 34 35.
  • Ice and Fire Golden Body: Allows him to endure the Ice and Fire Yin Yang Well’s hot and cold waters without injury after refinement 86.
  • Fire Dragon King’s Torso Bone: Provides enough physical strength to shatter a boulder larger than himself with one punch 91.
  • Ice Dragon King’s Head Soul Bone: Strengthens his mind and ice attribute and expands his Sea of Consciousness more than a hundredfold 91.
  • Poison resistance: Neither Lin En nor Sageross is visibly affected by Dugu Yan’s Jade Phosphorous Blue Poison 80.

Training and Tactical Leadership

  • Creature conditioning: Designs daily strength-training routines for Sageross, including repeated squats while holding an enormous boulder 10.
  • Physical preparation: Uses exercise and whale rubber to improve his own tolerance for powerful Soul Rings 12.
  • Combat instruction: Trains Zhu Zhuqing through demanding sparring against Sageross and teaches her to assess opponents before committing to an attack 27 30.
  • Expedition planning: Studies forest routes with Shui Bing’er and selects water-attribute hunting grounds for Skywater’s students 47.
  • Foreknowledge: Uses knowledge from his previous life to identify opportunities, locate Ah Yin’s hiding place, and recognize the Ice and Fire Yin Yang Well 1 34 84.

Equipment & Items

  • Storage Soul Tools: Stores money, valuables, and supplies; obtains Zhu Zhuqing’s Storage Ring before returning a smaller ring for her journey 14 15.
  • Whale rubber: Consumes hundred-year whale rubber regularly and obtains one thousand-year piece during his Nuoding years. Later buys six thousand-year pieces for 8,000 Gold Soul Coins to support Zhu Zhuqing’s conditioning 12 30.
  • Octagonal Mysterious Ice Grass and Infernal Delicate Apricot: Takes the two herbs simultaneously before completing his ice-and-fire refinement 86 91.
  • Potted Blue Silver Emperor: Removes Ah Yin from the hidden waterfall cave and takes her away in a flowerpot 34.
  • Gold Soul Coin cards: Uses cards to hold substantial earnings from arena betting and protection payments 28 60.

Relationships

  • Lao Jierui — Village chief who finds and raises him, accompanies him to his awakening, and provides money for his academy necessities 1 3.
  • Sageross — Principal martial soul and training partner. Their growth is reciprocal; Lin En treats him affectionately and credits his endurance during difficult absorptions 6 7 10 18.
  • Ingkaros — Second martial soul, initially hidden as a safeguard and later deployed beside Sageross 4 36.
  • Zhu Zhuqing — Begins as a paying rescue client and becomes his traveling companion, trainee, teammate, and romantic interest. Their relationship develops through training, mutual support, and kisses 14 24 30 46 71 73 74.
  • Tang San — Former dormmate and rival. Their early spar leads to growing distance; Tang San later vows to defeat him fairly 8 10 59.
  • Yu Xiaogang — Would-be mentor whom Lin En rejects and ridicules. Lin En deliberately seeks to undermine his influence over Tang San 2 9 10.
  • Xiao Wu — Former dormmate whose challenges he initially dismisses. He later warns her that her identity has been exposed and advises her to remain close to Ning Rongrong, while privately viewing her as a future ring-and-bone opportunity 4 8 81.
  • Shui Bing’er — Skywater teammate and vice-captain during the forest expedition; assists with route planning and the victory over Heaven Dou 47 81.
  • Shui Yue’er — Skywater classmate with whom he frequently flirts and trades teasing remarks 46 60 79.

  • Shui Qingyue — Arranges his life at Skywater and appoints him leader of its soul-hunting operation 43 46.
  • Ning Rongrong — Rescued traveler, would-be recruiter, and later opposing teammate. He rejects her sect invitation and charges a substantial protection fee 52 56 60 81.
  • Dugu Yan — Initially hostile opponent who becomes his patient and introduces him to Dugu Bo; grows grateful and increasingly attracted to him 81 83 84 88 89.
  • Dugu Bo — Initially threatens and pressures him, but becomes an ally after treatment. Offers future assistance and agrees to help obtain his fifth ring 84 87 89.

Story Role / Major Arcs

Nuoding Academy

Lin En enrolls after Director Su recognizes his innate full soul power. He defeats Wang Sheng through Sageross but refuses responsibility for Dorm Seven. With Teacher Niu’s assistance, he obtains his first ring, then independently develops his cultivation and Sageross’s training. His victory over Tang San deepens their rivalry and exposes the gap between Sageross’s abilities and Yu Xiaogang’s expectations 3 4 6 8 9 10.

Mercenary Work and Zhu Zhuqing

After graduation, Lin En returns to mercenary work to fund further schooling. He deliberately joins predatory groups, waits for them to attack him, and takes their valuables after killing them. The resulting “Mercenary Killer” reputation makes further infiltration difficult 12 13.

He subsequently intervenes in Zhu Zhuqing’s pursuit, repeatedly charges both sides, and eventually has Sageross kill her pursuers. Zhu Zhuqing remains with him, first as a paying companion and later as his trainee. During their travels, he acquires the Eight Spider Lances, earns arena winnings in Heaven Dou City, and funds her physical conditioning 14 15 18 24 28 30.

Fourth Ring and Academy Recruitment

Lin En steals Ah Yin and the Blue Silver Emperor Right Leg Bone from the waterfall cave near Holy Soul Village. The bone strengthens his previously vulnerable body and brings him to the threshold for his fourth ring. After a joint mantis assault defeats the Blade Thornspine Dragon, his cultivation reaches rank forty-five 34 35 36.

Seeking institutional backing without exposing Zhu Zhuqing’s sensitive identity at Heaven Dou Royal Academy, he challenges the Four Elements academies. He postpones accepting Godwind Academy’s generous offer and ultimately joins Skywater Academy alongside her 37 40 43.

Skywater Captain

Appointed captain of a twelve-person soul-hunting squad, Lin En leads Skywater students through the Star Dou Great Forest. The expedition brings another confrontation with Shrek, the rescue of Ning Rongrong, and the defeat of the Giant Swamp Crocodile King. He helps the students obtain their rings but refuses recruitment into the Seven Treasure Glazed Tile Sect 46 47 49 52 55 56.

At the academy, his meridian treatments support both Zhu Zhuqing’s development and Lan Susu’s breakthrough. He then proposes a warm-up match against Heaven Dou Royal Academy and helps Skywater win decisively, using his own external Soul Bone while Sageross attacks independently 71 75 80 81.

Ice and Fire Yin Yang Well

After identifying Dugu Yan’s poisoning, Lin En gains access to Dugu Bo’s hidden cultivation site. He withstands Dugu Bo’s intimidation, completes ice-and-fire body refinement, and evolves his external Soul Bone. Treating the Dugu family’s inherited poisoning turns their initial suspicion into an alliance 81 84 86 87 88 89.

He subsequently absorbs the Dragon Kings’ God-Level Soul Bones and joins Dugu Bo in searching for powerful Soul Beasts. The latest supplied scene leaves him preparing to hunt a seventy-thousand-year Purple Intent Spider Emperor to strengthen his Iceflame Eight Spider Lances 90 91.
