Background / History

Transmigration and aptitude test

Lei Lin transmigrated into the Zi'ao Family of the Fenlai Kingdom after falling asleep during an overtime shift in his previous life. He initially regarded the family as a modest but fortunate starting point: declining, yet free of an inherited blood feud or dangerous bloodline burden. 1

At six, he tested with medium Thunder Element affinity but super-grade spiritual energy—ninety-six times that of his peers. Though disappointed by his elemental affinity, he began magic cultivation immediately because his spiritual energy offered the fastest route to early self-protection. 2

His initial Golden Finger, the “Random Small Commodity Craft Exchange System,” supplied mundane manufacturing knowledge and the 24-Style Simplified Taiji Manual. Taiji earned him the favor of Sa'er, an eighth-rank Wild Thunder Guard member who became his master. 1

During his first meditation session, his newly condensed magic power vanished and was replaced by an insect later identified as the Telecommunication Gu. The Gu became the source of his lightning-law comprehension and abnormal physical evolution. 2 3 24

Rise of the Zi'ao Family

By fifteen, Lei Lin had become the Zi'ao Family's head. He provided development plans and commodity-production methods while Jinli'an and the Elder Council handled implementation. His policies expanded education, vocational training, and recruitment among commoners across the family's five territories. 4

He publicly revealed himself as a seventh-rank Thunder mage by creating a lightning-based flight spell, drawing attention from major powers across the Fenlai Kingdom. He then sought access to higher-rank magic through the Radiant Church rather than joining Sa'er's Wild Thunder Guard. 6

Bloodline research and the Chaotic Territory

Lei Lin's continually strengthening physique, despite no known magical-beast ancestry in the Zi'ao Family, led him to prioritize bloodline research. He later concluded that the Telecommunication Gu's “Dao of Information” manifested in his body as a bloodline, pushing him toward a divine-beast-like transformation. 12 24

He established a laboratory in the Chaotic Territory and planned the Zi'ao Family's expansion around Nifeng City. Beneath the laboratory site, he discovered both a Magic Crystal Mine and a dangerous Planar Secret Chamber, but chose not to enter without Saint Realm strength. 31

Personality

Lei Lin is calculating, cautious, and strongly motivated by self-preservation. He studies the possible butterfly effect of his actions and frequently avoids direct interference when he believes events may be dangerous to alter. 3 9

He is ambitious but pragmatic. He refuses Falling Leaf's offer of apprenticeship because he values pursuing his own path and obtaining dragon blood for research more than gaining a Saint Realm master. 25

Despite his utilitarian planning, he forms genuine attachments. He repeatedly protects Lin Lei and Beibei, halts unsafe bloodline trials rather than forcing results, and prioritizes Lin Lei's survival over continuing his own research. 30 39 40

Abilities & Skills

Law of Lightning

Lei Lin's Telecommunication Gu grants a direct connection to a sliver of the Law of Lightning, allowing him to develop techniques beyond conventional Thunder Element magic. 3 4

• Manipulates blue-purple lightning. 3
• Uses law comprehension to meet foundational Saint Realm requirements ahead of normal cultivation progression. 4
• Applies electromagnetic principles from his previous life to magic, battle qi, movement, healing, and alchemy. 6 10

Electromagnetic Induction

A covert reconnaissance technique based on the Telecommunication Law.

• Detects activity across several miles without obvious energy fluctuations. 8
• Allows Lei Lin to monitor targets, including Lin Lei, from a distance. 8 39
• Can detect outwardly radiated spiritual energy as electromagnetic waves, though it cannot reveal Delin while Delin remains concealed. 39

Lightning Step and Flight

Lei Lin developed both high-speed movement and aerial mobility through lightning-based techniques.

• Lightning Step gives him speed comparable to a ninth-rank expert. 14
• His self-created Thunder Element Flight Technique bypasses the usual pre-Saint restriction on flight outside the Wind Element. 6
• He can use flight to evade non-flying opponents and fight from high altitude. 21 22

Electromagnetic Cannon / Railgun

Lei Lin's strongest offensive technique uses his weapon, Judgment, as a launched projectile.

• Requires charge time to reach effective ninth-rank power. 11 21
• Can strike targets at extreme speed and was used to disable or kill black-clad ninth-rank opponents. 20 22
• After optimizing its principles, Lei Lin increases the technique's power by roughly fifty percent and shatters the defensive magic of ninth-rank mage Gilmore. 36

Electrotherapy

Lei Lin uses controlled lightning currents, magic power, and battle qi to stimulate cellular vitality.

• Rapidly stabilizes and heals external injuries. 9 10
• Restores Lin Lei's injuries after Nina's ambush and later heals him following their spar. 9 49
• Excessive use may shorten lifespan, though Lei Lin considers this negligible for those who reach the Saint Realm. 10

Alchemy and Bloodline Research

Lei Lin is a prominent young alchemist whose research focuses on magical bloodlines, cultivation enhancement, and experimental dragon-blood preparations. 11 15

• Created the commercially popular Lightning Robe and Thunder Punishment. 11
• Developed Dragonblood Potions from ninth-rank Black Dragon blood and Saint Realm Silver Dragon blood. 27
• Stopped Lin Lei's awakening trials after the initial formulas failed, choosing further research over unsafe experimentation. 29 30
• Created temporary magical-beast bloodline modifications that can raise a fifth-rank warrior to seventh-rank strength for approximately three months. 32
• Warns that permanent bloodline enhancement fixes a subject's future potential and can halt later growth. 32

Magic Arrays

Lei Lin studies and constructs magic arrays alongside his alchemical work.

• Activates protective arrays before high-level combat. 5
• Recognizes the extraordinary value of the sealing array in Misty Valley and traces its structure before Dylin's release. 41 42
• Identifies the Violet Blood Soft Sword as the divine-artifact core of the sealing array. 42

Equipment / Weapons / Items

• Thunder God set — Custom adventurer equipment combining offensive, defensive, and survival functions. Its output scales with Lei Lin's magic power and battle qi; with Judgment as a catalyst, it can threaten ninth-rank experts after sufficient charge time. 11
• Judgment — A Black Gold Straight Blade designed and forged by Lei Lin. It serves as both his primary weapon and the projectile catalyst for the Electromagnetic Cannon. 11 22
• Lightning Robe — A lower-cost defensive magic item designed for adventurers; its protection is limited to roughly fifth-rank attacks. 11
• Thunder Punishment — An electromagnetic weapon designed mainly for third- and fourth-rank users, with burst mode capable of threatening fifth- and sixth-rank opponents. 11
• Communication Crystals — Magic communication devices created by Lei Lin. Later models can store up to fifty messages and do not require both users to activate them simultaneously. 14 31
• Space Ring — A small-capacity storage ring given to him by Falling Leaf. 41

Relationships

• Jinli'an — Father and former head of the Zi'ao Family. Jinli'an supports Lei Lin's cultivation and implements his development plans for the family territories. 1 4
• Guyue — Mother. She is notably doting and supports his future regardless of his aptitude results. 1 2
• Sa'er — Master and eighth-rank Wild Thunder Guard member. Sa'er values Lei Lin's warrior talent, initially disapproves of his focus on magic, and later recognizes that Lei Lin has been holding back. 4 5
• Windsor — Fiancée. She offers practical counsel when Lei Lin struggles over whether to reveal the truth of Hogg's death to Lin Lei. 6 43
• Luo Lin — Fiancée and member of Lei Lin's household. 7 44
• Lin Lei — Close friend whom Lei Lin calls his younger brother. Lei Lin guides, protects, researches alongside, and repeatedly intervenes to keep him alive. 8 15 39 49
• Beibei — Lin Lei's magical-beast companion. Initially suspicious of Lei Lin, Beibei accepts his help and later knowingly keeps Lei Lin's secret protection of Lin Lei concealed. 9 41
• Lantan — Fenlai princess and Four-Winged Angel. She fights beside Lei Lin against the Dark Church, heals him with Radiant Battle Qi, and provides Saint Realm dragon blood for his research. 20 23 24
• Falling Leaf — Saint Realm ascetic and Radiant Church leader. He offers to accept Lei Lin as a disciple, then becomes a source of Silver Dragon blood and other research materials after Lei Lin refuses. 25 26
• Laite — A Zi'ao Family associate and early supporter. Lei Lin tests a temporary bloodline modification on him, raising his strength from roughly fifth-rank to seventh-rank. 1 32

Story Role / Major Arcs

Magic Beast Mountain Range friendship

Lei Lin deliberately approaches Lin Lei in the Magic Beast Mountain Range, saves him from hostile adventurers and Wind Wolves, and establishes their “Big Brother” relationship. He later treats Lin Lei after Nina's ambush and accompanies him through further training without directly taking over his battles. 7 8 9 10

Dragonblood experiments

After learning that Lin Lei is a Dragonblood Warrior descendant, Lei Lin trades Blue Heart Grass and future resources for cooperation in bloodline research. He receives the Dragonblood Secret Manual and samples from the Baruch Family, develops experimental potions, and eventually suspends the initial failed trials. 13 15 27 29 30

Dark Church ambush

While pursuing Saint Realm Tyrannosaurus Rex blood, Lei Lin is targeted by the Dark Alliance. He attempts to negotiate for Lantan and his butler's safety, then uses the Electromagnetic Cannon and his mobility to fight back when escape becomes necessary. 19 20

Misty Valley and Lin Lei's awakening

Lei Lin secretly protects Lin Lei during his return to the Magic Beast Mountain Range. When Lin Lei faces the Saint Realm Purple-Striped Black Bear and the Spine-backed Iron-Armored Dragon, Lei Lin intervenes and allows him to awaken his Dragonblood Warrior bloodline by consuming the dragon's blood. 39 40 41

After the sealing array collapses, Lei Lin identifies the Violet Blood Soft Sword as a divine artifact and gives it to Lin Lei, retaining only the Purple-Striped Magic Bear's Saint Realm magic core. 42

Conflict with the Radiant Church

Lei Lin conceals the truth behind Hogg's death because he fears Lin Lei may act before he is strong enough. When Lin Lei discovers the Radiant Church's involvement and pursues revenge, Lei Lin warns him about the Church's true strength by defeating him decisively despite being only eighth-rank. 43 47 48 49

Notable Quotes

“The most terrifying thing in the Magic Beast Mountain Range has never been the magic beasts, but the peers with ulterior motives.” 7

“A beautiful life requires powerful strength to protect it!” 15

“Do not let this sword gather dust! Do not let your bloodline gather dust!” 42

Trivia

• Lei Lin and Lin Lei's names are presented as a source of “fate” because their characters are reversed. 8
• His original Golden Finger initially seemed nearly useless, supplying production knowledge such as soap, spicy strips, and toilet paper. 1
• Lei Lin's commercial inventions and territorial development help transform the Zi'ao Family from a declining noble house into a rapidly rising power. 4 11
