History

Blackwater Village and Green Mountain Village

Lu Yuan was a low-ranking constable when he killed the Gray-Skinned Rat Demon in Blackwater Village with his rusty saber. Injured in the encounter, he concealed his involvement while Dou Chu and Shi Yun took credit for reporting the demon's death. He then brought the orphaned Xu Shengnan back to Green Mountain Village, where his family took her in. 2

His system made demon hunting essential to his survival: killing demons produced EXP for improving his techniques, while his initial remaining lifespan was measured in days. He killed a Bristle-Haired Boar Demon to protect Liu Tieshan and spent the resulting EXP on Wild Bull Force. 5

Withered Wood Fist Hall

After selling an Azure Fish Demon's head, Lu Yuan received Yan Nishang's recommendation to study at Withered Wood Fist Hall. Chen Wang initially judged his meridians and bone seams unsuitable for martial arts, but accepted him after seeing Yan Nishang's jade pendant. 12 13

Lu Yuan concealed the progress of his body-tempering cultivation. Chen Wang mistook Lu Yuan's skin returning to its natural color after the second level of Grinding Force for failure, nearly urging him to abandon martial arts before witnessing his true ability in the challenge against Mountain-Calming Martial Hall. 31 37

Conflict with Officials and Bandits

When Jia Ke and the Garrison Office extorted Green Mountain Village, Lu Yuan secretly followed Jia Ke's group and killed them. Later, Chen Kuang sent Dou Chu and four First-Rank Upper martial artists to assassinate him; Lu Yuan defeated them, interrogated Dou Chu, and removed the bodies to erase evidence. 11 28

Chen Kuang subsequently targeted Lu Yuan's family through Black Wind Stronghold. Lu Yuan returned to Green Mountain Village, slaughtered Zhou Hu's mounted bandits, then climbed Black Wind Mountain alone and killed the Third-Rank Lower Realm bandit chief Dou Jun. 55 56 57

After using a temporary Sixth-Rank trial token to kill the Crimsonflame Raccoon Dog, Lu Yuan eliminated Black Wind Stronghold's surviving bandits to prevent witnesses from exposing his abnormal strength. He secured official protection by presenting Registrar Lu Hai with evidence that the stronghold had raised demon beasts on human blood food. 58 59 60

Black Triangle Mountain and the Ancient Demon Battlefield

Lu Yuan joined the Demon-Slaying Team because its demon-hunting assignments offered the fastest route to EXP. During the first expedition into Black Triangle Mountain, he saved Lin Ruoxue, then separated from the group to hunt demon beasts alone. 39 44 45

Yan Nishang later provided him with a Demon-Seeking Orb and the damaged Withered Wood Breath-Absorbing Formula. Lu Yuan repaired the formula with 8,000 EXP, allowing him to efficiently turn Demon Power Origin into cultivation. 65 66

Using the orb and formula, he hunted Second-Tier demons for a month, unlocked the Grand Prize Wheel System, and rose to the Second-Rank Middle Realm. His pursuit of a Grave-Digging Beast led him into the Ancient Demon Battlefield, where he became entangled with Azure Rock Sword Manor and repeatedly fought its disciples. 67 68 69

Inside the battlefield, Lu Yuan hunted Third-Tier soul beasts for their exceptionally pure energy. He killed Ling Xiao and Xue Cheng after advancing his saber art to the Earth-grade Annihilating God-Slayer Saber, then continued hunting until reaching the Third-Rank Upper Realm. 76 78 80

Personality

Lu Yuan is intensely protective of his family and treats his cultivation as the means to keep them safe. He refuses to flee threats that could instead fall upon Green Mountain Village, and he repeatedly risks his life to defend his relatives and community. 33 56

He is calculating rather than impulsive. Lu Yuan hides his system, creates alibis, preserves witnesses when they may be useful, erases evidence when necessary, and seeks official backing after destroying Black Wind Stronghold. 11 26 28 60

Against demons and those who threaten his family, he is ruthless. He kills the Yellow Weasel Demon's cubs to prevent future retaliation, executes the surviving Black Wind Stronghold bandits to protect his secret, and rejects the Five Great Demon Houses' offer to collaborate in supplying human blood food. 19 59 63

Abilities & Skills

Demon-Slaying System

Lu Yuan's system awards EXP for demon kills, which he uses to upgrade martial arts and cultivation methods at extraordinary speed. It also tracks his lifespan, grants lifespan rewards for breakthroughs, and unlocks prize draws after he completes Beast Compendiums. 5 7 67 80

• EXP upgrades techniques but does not directly raise his realm; cultivation must still be obtained through training or refined Demon Power Origin. 65
• His first free draw produced the Three-Breath Sixth-Rank Martial Artist Trial Token. 58
• Completing the Second-Tier and Third-Tier Beast Compendiums unlocked the Grand Prize Wheel System and additional free draws. 67 80

Saber Arts

Lu Yuan's primary weapon is a rusty saber, which he uses with increasingly powerful demon-slaying arts.

• Basic Demon-Slaying Saber Technique reached Perfection before he entered the martial ranks. 5
• Blood-Baleful Demon-Slaying Saber evolved into the Mysterious-grade Nine Nether Blood-Prison Saber. 45 64
• The Nine Nether saber's baleful blood aura restrains, corrodes, and weakens demons, including soul-form demon beasts. 63 75
• He spent 30,000 EXP to advance it into the Lower Earth-grade Annihilating God-Slayer Saber, which killed Third-Rank Upper Realm Ling Xiao in one slash. 78
• Annihilating God-Slayer Saber consumes substantial inner force and is reserved as a decisive killing move. 79

Body Tempering and Strength

Lu Yuan combines Wild Bull Force, Ironhide Body-Tempering Art, and brutal body-tempering exercises to strengthen his physique.

• Wild Bull Force amplifies brute strength and close-quarters power; it later advances toward the Barbarian King's Giant Strength Art. 5 46 52
• Ironhide Body-Tempering Art accelerates healing during gravel training and greatly reinforces his skin membrane. 30 46
• He deliberately endured the Ghost-Faced Lynx's attacks to temper his body into the First-Rank Upper Realm. 53
• At the Third Rank, his Sinew Tempering grants penetrating force capable of splitting a large boulder with a saber strike. 76

Movement Arts

Lu Yuan acquired Carefree Steps from Yan Nishang in exchange for Demon Cores and later developed it into the Cloudtrace Carefree Art. 20 57

• Enables rapid evasion, pursuit, and concealment.
• Allowed him to avoid Dou Jun's spear attacks and deliver the killing blow. 57
• Lets him evade stronger opponents rather than commit to unfavorable direct exchanges. 69
• Its later advancement path leads toward the Profound-grade Grand Void Shadowless Step. 80

Withered Wood Breath-Absorbing Formula

This cultivation method devours Demon Power Origin released after a demon beast's death and refines it into Lu Yuan's own cultivation. 66 67

• Lu Yuan repaired its damaged copy into a complete version with 8,000 EXP. 66
• A Second-Tier Lower-Grade demon's origin can equal several days of ordinary cultivation. 67
• Soul beasts within the Ancient Demon Battlefield provide even purer energy, with almost no loss during refinement. 76
• Its next advancement is the growth-type Earth-grade Myriad Forms Azure Wood Formula. 80 81

Secondary Sword Arts

Lu Yuan learned sword manuals from Ling Xiao and Xue Cheng to broaden his combat options. 78 79

• Azure-Green Sword Art advanced into Azure-Green Sky-Breaking Sword. 79
• Star-Piercing Sword advanced into Starflare Armor-Piercing Sword, specializing in concentrated piercing power. 79

Equipment

• Abyss-Facing Bow — Low-Grade Profound Rank bow obtained from the Grand Prize Wheel; gives him a long-range killing method. 68 79
