Background

Lin Yu was originally a Star Luo Empire soldier who was defeated at the border and imprisoned in a Heaven Dou Empire dungeon. With the Star Luo Empire unwilling to ransom its captured soldiers, he and the other prisoners were scheduled for execution the following day. 1

During this crisis, Lin Yu awakened the Starry Express as his Martial Soul. Although it began with only Innate Soul Power level 1 and could not absorb Soul Rings itself, it could Warp through space-time and form Golden Contracts that shared a companion's Martial Soul with him. He used its Warp ability to escape execution, arriving in the Extreme North ten thousand years in the future. 1

In the Extreme North, Lin Yu became involved in the battle between the heavily injured Snow Empress and a Rank 9 Soul Engineer. After the Snow Empress killed the engineer at severe personal cost, she signed Lin Yu's contract, granting him the Heavenly Snow Woman Martial Soul. Their accompanying life-sharing arrangement healed her injuries by draining his life force, forcing Lin Yu to seek rapid advancement or die. 3 4

Appearance

Lin Yu is a handsome young man who appears to be around eighteen. His appearance readily attracts attention, including Xue Ke's immediate fascination at Moonlight Pavilion and Tang Ya's recognition of him as the most handsome among Shrek Academy's recruits. 14 56 63

• Often described as exceptionally handsome or fitting Xue Ke's preferred type. 14 63
• His hair turns white after his initial temporal displacement; his past self is later seen as a white-haired youth wrapped in Ice Silkworm skin against the Extreme North's cold. 6 49
• Initially wears tattered prisoner clothing after escaping the Heaven Dou dungeon. 1 49

Personality

Lin Yu is defined by survival-driven persistence. He refuses to accept inevitable death, rapidly cultivates under the Snow Empress' life-sharing deadline, risks absorbing Spirit Rings beyond conventional limits, and endures twenty days of Soul Power extraction despite repeatedly nearing collapse. 4 5 8 18

He is highly calculating and often engineers opportunities before presenting himself as a helpful stranger. He uses future knowledge to gain Qian Renxue's trust, manipulates Ma Xiaotao into providing cultivation pills, and carefully stages encounters to impress Zhu Qing and secure a contract. 8 32 56 58

Despite his opportunism, Lin Yu treats his contracted companions as people he must protect. He refuses to abandon the Ice Empress during the Nine-Headed Bat King's attack, even when escaping alone would have been safer. He also insists that agreements should be based on mutual consent rather than force. 13 47

Lin Yu frequently teases those close to him, especially the Snow Empress and Qian Renxue. His humor can be provocative, but he becomes serious whenever his companions' survival or future is at stake. 12 16 17

Abilities & Skills

Starry Express Martial Soul

The Starry Express is Lin Yu's original Martial Soul and the foundation of his unusual cultivation path. It cannot receive Soul Rings directly, but it allows Lin Yu to invite powerful companions aboard and share their Martial Souls through Golden Contracts. 1

• Space-time Warp — Can travel across locations and eras, including jumps of ten thousand years into the future or past. 1 6
• Golden Contracts — The contracts are generated by the Starry Express itself; they share Martial Souls rather than steal them. 3
• Power scaling through companions — Stronger or complementary contracted Martial Souls provide greater Soul Power increases. 1 19 37
• Temporal timeline management — Lin Yu can move between overlapping timelines, allowing multiple versions of the Starry Express to coexist without immediately collapsing history. 39
• Mobile base — After Ma Xiaotao joins, the Starry Express manifests as a physical train with four spacious carriages for Lin Yu and his companions. 37
• Limitation — It began with Innate Soul Power level 1, cannot take Spirit Rings itself, and initially offered little direct combat strength without powerful contract companions. 1

Contracted Martial Souls

By Chapter 79, Lin Yu possesses nine shared Martial Souls in addition to the Trailblazing power derived from his Martial Soul True Body. 79

• Heavenly Snow Woman — Obtained from the Snow Empress; grants Ultimate Ice and Snow power and protects Lin Yu from the Extreme North's cold. 3 4
• Six-Winged Angel — Obtained through Qian Renxue; provides a top-tier light-attribute Martial Soul. 17
• Evil Fire Phoenix / Nine-Headed Phoenix — Obtained from Ma Xiaotao; later evolves alongside her Martial Soul into the Nine-Headed Phoenix. 37 52
• Ice Jade Emperor Scorpion — Obtained from the Ice Empress; its immense cultivation grants Lin Yu a large reserve of Soul Power. 43 44
• Hell Spirit Cat — Obtained from Zhu Qing; a Dark Attribute Martial Soul that complements the Six-Winged Angel. 61 70
• Dark Blue Silver Grass — Obtained from Tang Ya; another Dark Attribute Martial Soul used in Lin Yu's rise to Soul Emperor. 68 70
• Ice Bear Martial Soul — Obtained from the Ice Bear King after it signs a contract to pursue a path toward godhood. 72
• Three Lives Soul Suppressing Cauldron — Obtained through Xiao Xiao's contract. 77
• Nine Phoenix Auspicious Flute — Obtained through Xiao Xiao's contract; complements the Three Lives Soul Suppressing Cauldron. 77

Ultimate Ice and Snow Techniques

Lin Yu's ice-based Martial Souls provide both large-scale battlefield control and high-output finishing attacks.

• Thousand Mile Ice Seal — An ice-based Soul Skill used to freeze the dungeon and create an escape opportunity after returning to the past. 6
• Emperor Sword — A fifth-ring single-target technique that condenses into a giant deep-blue sword capable of piercing through defenses. 52
  • Its power makes Lin Yu nearly invincible against opponents of the same rank. 53
  • Its major limitation is extremely high Soul Power consumption; he can barely use it twice. 53
• Emperor's Palm: Great Cold Without Snow — A sixth-ring technique whose force exceeds Emperor Sword and can defeat a Soul Sage. 70
• Ice immunity — After obtaining the Heavenly Snow Woman and Ice Jade Emperor Scorpion Martial Souls, the Extreme North's freezing climate no longer affects him. 49

Trailblazing Divine Power

Upon reaching level 70 and manifesting his Martial Soul True Body, Lin Yu's connection to the Starry Express changes: Trailblazing becomes an independent divine power within him rather than a power he can access only through the train. 78

• Independent Warp — Can traverse space and time without summoning the Starry Express. 78
• Time reversal — Rewinds local time, demonstrated when Lin Yu restores a conversation aboard the train to an earlier moment. 78
• Spatial confinement and expansion — Can imprison opponents in space or expand an enclosed space without apparent limit. 78 83
• Soul Ring manipulation — Grants his nine Martial Souls suitable Soul Ring configurations across past, present, and future, then adjusts their years to the highest levels he can bear. 79
• Divine powers — Demonstrates five ultimate divine powers: Ice and Snow, Nirvana, Light-Dark, Death, and Creation. 87
• Historical stabilization — Uses space power to alter the Battle of Jialing Pass while preventing the resulting past changes from destroying the established future. 87

Future Knowledge

Lin Yu uses knowledge retained from his former life and observations across time to predict major events. He leaves Qian Renxue lists of future developments involving Heaven Dou, Martial Soul Hall, and Tang San, allowing her to verify his apparent foresight. 8

• Uses temporal knowledge to prearrange Soul Beast hunts and meetings years in advance. 18
• Identifies future contract candidates whose Martial Souls will become useful only later in their lives, including Ma Xiaotao and Tang Ya. 20 26
• Treats time travel as a strategic tool for changing outcomes rather than merely escaping danger. 11 68

Equipment / Items

• Rank 9 God Sealing Platform — Originally used against Lin Yu by a Rank 9 Soul Engineer; Lin Yu later retrieves and repairs it, using it during the effort to prevent Qian Daoliu's possession. 3 52
• Cockscomb Phoenix Sunflower — Given to Ma Xiaotao to resolve the Evil Fire that had plagued her for years. 37
• Mysterious Water Pills and Soul Ascension Pill — Cultivation pills Lin Yu obtains from Ma Xiaotao and uses to improve his innate Soul Power and Soul Power level. 32

Relationships

• Snow Empress — Lin Yu's first contract companion. Their life-sharing bond initially places both at risk, but develops into deep trust, frequent teasing, and mutual affection. 3 4 61 83
• Qian Renxue — Contracted Angel Martial Soul companion and strategic ally. Lin Yu relies on her planning, influence, and long-term preparation of Spirit Rings; she trusts him to help preserve her godhood against the Sea God and Shura God. 17 18 19
• Ma Xiaotao — Contract companion whose Evil Fire Phoenix becomes the Nine-Headed Phoenix. Lin Yu resolves her Evil Fire using the Cockscomb Phoenix Sunflower, while her Martial Soul becomes a key complement to his Ultimate Ice. 37 52
• Ice Empress — Contract companion rescued from the Sky Dream Ice Silkworm's Million-Year Molted Shell. Her Ice Jade Emperor Scorpion Martial Soul greatly strengthens Lin Yu, and she comes to recognize his reckless but genuine pioneering spirit. 42 44 47
• Zhu Qing / Zhu Zhuqing — Contract companion seeking freedom from the Zhu family's cruel fate. Lin Yu manipulates their meeting to gain her trust, while she provides him with her family's method for controlling Dark Attribute Martial Souls. 56 61
• Tang Ya — Contract companion with Dark Blue Silver Grass. Lin Yu helps resolve her obsession with revenge and reunites her with her surviving parents after using time travel to arrange their rescue. 68 70
• Ice Bear King — Contracted Soul Beast who believes Lin Yu may become a God of Ice and Snow. It becomes strongly attached to him and mistakenly calls him “Dad.” 72 73
• Xiao Xiao — Contract companion recruited after Lin Yu overwhelms Shrek's Outer Court Core Disciple selection. Her Twin Martial Souls propel him to level 70. 77
• Silver Dragon King — A powerful being Lin Yu approaches openly to discuss a mutually beneficial contract based on their respective Trailblazing powers. She later travels with the Starry Express group. 79 88
• Qian Daoliu — Qian Renxue's grandfather. Lin Yu helps save him from the Nine-Headed Bat King's possession and returns a repaired Rank 9 God Sealing Platform to the conflict. 47 52

Shrek Academy and Ma Xiaotao

Lin Yu enters Shrek Academy to reach Ma Xiaotao, publicly demonstrates his Ultimate Ice abilities, and eventually contracts her. By curing her Evil Fire and gaining the Evil Fire Phoenix Martial Soul, he turns a dangerous condition into a major power increase for both of them. 27 37

Ice Empress and the Extreme North Timelines

To secure the Ice Empress' contract, Lin Yu repeatedly navigates overlapping Extreme North timelines.
