Chen Xin

Biodata

Power Progression

Background / History

Chen Xin is the son of Chen Jianjun, a renowned swordsman who reached level 98 after receiving insight from Xu Xiao. Concerned that his son was merely following his own sword path rather than creating one, Chen Jianjun allowed Xu Xiao three years to guide Chen Xin's development. 10 11

He first meets Xu Xiao's group with open contempt, dismissing them as mere level-20 spirit masters. Yue Guan and Gui Mei immobilize him with their Martial Soul Fusion Skill, after which Dugu Bo and Xu Xiao defeat him. Seeing their extraordinary spirit rings and coordination, Chen Xin recognizes his own arrogance and accepts his father's judgment. 19

After learning that Xu Xiao's letter had enabled Chen Jianjun's breakthrough and clarified his sword path, Chen Xin chooses to join the group as its fifth brother. Xu Xiao begins retraining him away from reliance on the Seven Kill Sword, first through soft-sword technique and later through the heavy sword. 20 21

As Chuan Ling's Fifth Hall Master, Chen Xin also provides the young faction with access to the Chen Family's prestige and resources. His intervention protects the Ye Family from the Seven Treasure Glazed Tile Sect and enables Gu Rong to leave its academy without bearing the burden of retaliation alone. 41 43 44 62

After returning from Slaughter City, Chen Xin receives a million-year fifth soul ring. Ye Shengxin treats his excessive killing intent and restores his spiritual condition before he resumes faction duties. Chen Xin then works with Ye Lin to establish Chuan Ling's Heaven Dou base, using the Chen Family's influence to purchase a large estate and its surrounding territory. 137 139

Following years of cultivation under Xu Xiao's guidance, Chen Xin grows beyond his father's shadow and becomes one of Chuan Ling's foremost combatants. Although he loses his challenge against the level-99 Chen Jianjun, the duel confirms the independent sword path he has forged. 155 156

He subsequently reaches the level-70 threshold and agrees to remain with Ling Yuan on the Sun Moon Continent rather than leave her there alone. The two retain access to the Spirit Pagoda through tokens, allowing them to return or contact Xu Xiao when necessary. 213

Later, he journeys to the God Realm with Gui Mei and impresses the divine entities, ultimately securing the Death God as a personal mentor without binding himself to a specific divine inheritance. After the Death God's divine consciousness is sealed, Chen Xin begins cultivation under the Destruction God King's guidance. 310

Chen Xin and Ling Yuan's daughter, Chen Yuansha, later awakens twin martial souls—a sword and a kite—with Innate Full Soul Power. Chen Xin directs her foundational sword training through a measured daily routine, continuing the family's swordsmanship tradition. 293 353

Appearance

Chen Xin is introduced as a youthful, somewhat boyish swordsman with a handsome appearance and a haughty expression. 19 36

• Carries a sword, initially planting it before him when waiting for Xu Xiao's group. 19
• Uses a soft sword during his foundational sword-technique training. 20 42
• Later keeps a heavy sword on his back for daily cultivation. 59 85 156
• Wields the evolved Deadly Seven Kill Sword, which radiates intense killing intent. 36 43
• During his duel with Chen Jianjun, displays five soul rings colored purple, purple, purple, red, and white-gold. 156

Personality

Chen Xin begins proud, competitive, and dismissive of those he perceives as weaker. His defeat by Xu Xiao's brothers forces him to recognize that talent exists beyond his experience, making him more receptive to guidance. 19 20

He is intensely devoted to swordsmanship and seeks a sword path distinct from his father's. This drive makes him disciplined in Xu Xiao's harsh training, eager to test himself against stronger opponents, and willing to challenge even Chen Jianjun. 20 21 37 155

Once he accepts Xu Xiao as his eldest brother, Chen Xin is loyal and protective of the group’s secrets. He values brotherhood, looks after Gu Rong in battle, and intervenes when he sees Gu Rong mistreating the weak. 28 42 127

His confidence remains intense after his growth. At level 67, he boasts that once he becomes a Title Douluo, his Seven Swords will be enough to slay the Evil Eye Tyrant Lord. 167

Despite his own competitive nature, he can offer patient advice about cultivation. When Gu Rong becomes preoccupied with choosing his path, Chen Xin tells him that calming his heart and ceasing to struggle over the choice will help him recognize what suits him. 204

As a parent and instructor, he balances discipline with restraint. Although Xu Xiao initially worries that Yuansha's iron-sword practice is excessive, her measured daily training schedule reassures him that Chen Xin is not overworking her. 353

Abilities & Skills

Swordsmanship

Chen Xin's sword style develops from the Seven Kill Sword's direct ferocity into a broader path founded on technique, a soft sword, and the heavy sword.

• Practices without spirit power or his Seven Kill Sword martial soul in the Spirit Ascension Platform. 21 37
• Uses soft-sword technique to pressure Gu Rong's Bone Dragon defenses and target vital points. 42
• Attains the realm of Heavy Sword Without Edge through extended heavy-sword cultivation. 85
• At that stage, has not yet attained the higher understanding in which all things can serve as swords. 85
• Can sever all three heads of the Dark Gold Three-Headed Bat King simultaneously. 127
• Continues to carry his heavy sword rather than setting it aside, using it for daily cultivation even after developing his own sword path. 156
• Teaches Chen Yuansha foundational swordsmanship using an iron sword and a regulated daily routine. 353

Deadly Seven Kill Sword

Sword Sever Grass evolves Chen Xin's Seven Kill Sword martial soul into the Deadly Seven Kill Sword, dramatically increasing its killing power. 36

• Seven strikes can kill an opponent of the same rank; nine can kill a stronger opponent, though effectiveness depends on the target's actual strength. 36
• The Deadly Seven Kill Sword's nine-strike killing sequence is an all-or-nothing attack; if its nine strikes cannot kill the target, Chen Xin considers himself finished. 37
• The nine killing swords are executed through his soul skills rather than being a separate Chen Family self-created technique. 37 156
• Although the complete sequence contains nine strikes, he can only execute its first five swords while at level 59. 156
• The martial soul's sword intent alone shatters Gu Rong's defense. 42 43
• Its attack power is described as strong enough that even the Clear Sky Hammer would avoid it. 43

Soul Skills

Following his martial-soul evolution, Chen Xin's first three soul skills gain the Sword Sever Grass's sharp, piercing qualities. 37

• Void Sever / Void Severing — renamed first soul skill; its full demonstrated name is Longsword Wind Draw—Void Severing. Used against Chen Jianjun alongside the Divine Slaughter's Domain. 37 156
• Heart Sever / Heartless Severing — renamed second soul skill; its full demonstrated name is Frost Sword Shatters the Void—Heartless Severing. Follows Void Sever in rapid combinations. 37 156
• Grief Sever / Sorrowful Severing — renamed third soul skill; its full demonstrated name is Sorrow Sword, Desolate Nether—Sorrowful Severing. Part of his successive sword-strike barrage. 37 156
• Emotion Severing / Emotional Severing — fourth soul skill, used against Chen Jianjun. 156
• Law Severing — fifth soul skill listed among his upgraded techniques. His fifth ring is a million-year platinum ring bestowed by Xu Xiao. 137 156

The Seven Kill Sword True Body used during the father-son duel belongs to Chen Jianjun, who invokes it in response to Chen Xin's attacks; it is not an established seventh skill of Chen Xin at that point. 156

Divine Slaughter's Domain

Chen Xin obtains the Divine Slaughter's Domain after overcoming an inner-demon trial. 128

• Projects bloody killing intent that suppresses opponents. 156
• Supports his sword attacks, including Void Sever. 156
• His inner demon centers on failing to surpass Chen Jianjun and never reaching the peak of the sword path; he overcomes it without difficulty. 128
• His control over killing intent is not always stable after Slaughter City. The excitement of receiving his million-year fifth soul skill makes it difficult to suppress, requiring repeated healing from Ye Shengxin. 137

Combat Prowess

Chen Xin is regarded as one of Xu Xiao's strongest brothers and is often assigned frontline or protective duties. 49 155

• Defeats Gu Rong decisively despite initially testing him with a soft sword. 42 43
• Guards and intimidates a suspected soul beast in human form with precise, lethal sword placement. 49 50
• Works with Gu Rong to clear the Blood Sea's primordial-beast trial. 127
• At level 50, possesses a 600,000-year soul skill said to make him invincible among peers. 85
• After receiving his million-year fifth ring, believes that a single sword strike can defeat Ling Yuan, who has just obtained her fourth ring. 137
• At level 60, is acknowledged by Chen Jianjun as strong enough that even a Soul Douluo may not be his match. 156
• At level 59, his full strength remains insufficient to overcome Chen Jianjun's level-99 swordsmanship, though his father's response demonstrates that Chen Xin's attacks must be taken seriously. 156
• By the later stages of Chuan Ling's development, Chen Jianjun privately considers the possibility that Chen Xin has become stronger than him. This is an assessment rather than the result of a demonstrated rematch. 284

Other Techniques

• Sword flight — mounts his sword to travel rapidly, reaching the outskirts of the Blue Silver Forest with Gu Rong in approximately two hours. 131
• Danger perception — develops exceptionally strong vigilance and sensitivity to danger alongside Gu Rong after their years in Slaughter City. 131

Equipment / Weapons / Items

• Deadly Seven Kill Sword — evolved martial soul, formerly the Seven Kill Sword. 36
• Soft sword — issued by Xu Xiao as the foundation of his independent sword path. 20
• Heavy sword — forged by Chen Jianjun; used for the second stage of Chen Xin's sword training and carried during daily cultivation. 20 59 85
• Two jade bottles of Ice and Fire Yin-Yang Well water — used to incapacitate the Ten Headed Fierce Yang Serpent long enough to retrieve its inner core. 127
• Chen Family token — given to Ye Shengxin's father so he may seek Chen Jianjun's assistance if needed. 43
• Storage Soul Tool — carries the three swords supplied by Chen Jianjun before handing them to Xu Xiao. 20
• Spirit Pagoda access token — permits access to the pagoda and communication with Xu Xiao while he remains with Ling Yuan on the Sun Moon Continent. 213

• Chen Jianjun — Father. Chen Xin initially lives under his father's shadow but eventually challenges him in a sword duel, seeking to surpass him and later bring him to the God Realm. Chen Jianjun defeats him but recognizes the growth he has achieved under Xu Xiao. 11 155 156
• Yue Guan — Sworn brother. Yue Guan finds Sword Sever Grass, enabling Chen Xin's martial-soul evolution. 19 36
• Gui Mei — Sworn brother. Helps defeat Chen Xin at their first meeting and later welcomes him into the group. The two subsequently enter the God Realm together and agree to a future friendly contest under their divine instructors. 19 20 310
• Dugu Bo — Sworn brother and early guide in the Spirit Ascension Platform. He explains its rules to Chen Xin and purges the poison inflicted during their first clash. 20 21
• Gu Rong — Former acquaintance, rival, and later sworn brother. Chen Xin chastises him for bullying Ye Shengxin, defeats him, then supports his entry into their faction; they later fight as a close team. Chen Xin also advises him on finding his cultivation path, while Gu Rong remains interested in testing his defenses against Chen Xin's sword. 42 43 127 130 204 284
• Blue Silver King — Respected senior and ally. Chen Xin seeks his assistance in directing soul beasts against the Blue Lightning Tyrant Dragon Clan. 55 131
• Ling Yuan — Fellow faction member and later partner. Chen Xin impulsively misreads her arrival and attempts to carry out the group’s supposed “tradition.” He later remains with her on the Sun Moon Continent out of concern for leaving her alone. Their daughter is Chen Yuansha. 55 213 293 353
• Chen Yuansha — Daughter. Inherits sword and kite martial souls from her parents and awakens with Innate Full Soul Power. Chen Xin oversees her disciplined foundational sword training. 293 353

• Destruction God King — Divine cultivation instructor. Following the sealing of the Death God's divine consciousness, takes Chen Xin to cultivate and encourages him not to hold back in his future match with Gui Mei. 310

Story Role / Major Arcs

Joining Xu Xiao's Brotherhood

Chen Xin arrives under Chen Jianjun's three-year agreement with Xu Xiao, arrogantly dismisses the group, and is beaten after attacking them. He learns the truth behind his father's level-98 breakthrough, accepts Xu Xiao's mentorship, and becomes the fifth brother. 19 20

Forging an Independent Sword Path

Xu Xiao restricts him from using spirit power and the Seven Kill Sword during training, directing him through soft-sword and heavy-sword stages. Chen Xin's trust grows as the Spirit Ascension Platform improves his rings and broadens his understanding of sword use. 20 21 27 28

Deadly Seven Kill Sword Evolution

Yue Guan locates Sword Sever Grass for Chen Xin. The herb shatters and reforges his martial soul into the Deadly Seven Kill Sword, granting fearsome killing intent and transformed soul-skill attacks. 36 37

Conflict with Gu Rong

Chen Xin confronts his former acquaintance Gu Rong for bullying Ye Shengxin. He overwhelms Gu Rong, later requests that Xu Xiao accept him into the faction, and gains him as a sworn brother and combat partner. 42 43 44

He also kills most of Gu Rong's accompanying academy members, leaving one survivor to inform Ning Buqun that the Ye Family is under Chen Family protection and that Gu Rong is leaving the Seven Treasure Glazed Tile Sect. This intervention establishes a protective connection between the Chen and Ye families. 43

Slaughter City and the Blue Lightning Plot

After training in Slaughter City with Gu Rong, Chen Xin gains the Divine Slaughter's Domain. The two return stronger, disrupt the Blue Lightning Tyrant Dragon Clan's soul hunt, and seek the Blue Silver King's help in luring powerful soul beasts toward the clan. 127 130 131

Million-Year Ring and Chuan Ling's Heaven Dou Base

Xu Xiao bestows Chen Xin's million-year fifth soul ring after his return from Slaughter City. Its extraordinary attack power intensifies his excitement and killing intent, so Ye Shengxin provides repeated treatment before Chen Xin resumes his duties. 137

Working with Ye Lin, Chen Xin uses the Chen Family's influence to purchase a massive estate in Heaven Dou City and secure the surrounding hundred miles as Chuan Ling territory. Ye Lin then recruits workers to build according to Xu Xiao's blueprints, while Chen Xin arranges personnel before returning to cultivation. 139

Duel with Chen Jianjun

Chen Xin resolves to stop living beneath his father's shadow and challenges Chen Jianjun, now a level-99 Limit Douluo. Though defeated, he forces his father to acknowledge his strength and breaks through to level 60. 155 156

God Realm Journey and Mentorship

Entering the God Realm with Gui Mei under Xu Xiao's philosophy of self-made strength, Chen Xin catches the attention of the Death God, who accepts him as a disciple without requiring him to inherit the Death God's position. 310

After the Death God's divine consciousness is sealed for five God Realm years, the Destruction God King undertakes Chen Xin's cultivation guidance. Destruction and Evil arrange to compare Chen Xin and Gui Mei's progress after a year, and Chen Xin promises not to go easy on his second brother. 310

Continued Cultivation

Four years later, Chen Xin reaches level 67, placing him only three ranks from the Soul Sage realm. He remains determined to become a Title Douluo and confident that his Seven Swords will eventually let him challenge even the Evil Eye Tyrant Lord. 167

He is later confirmed to have reached the level-70 threshold. During Xu Xiao's arrangements on the Sun Moon Continent, Chen Xin agrees to stay with Ling Yuan, retaining the means to access the Spirit Pagoda and communicate with his eldest brother. 213

Training the Next Generation

Chen Yuansha's awakening reveals that she has inherited both her parents' martial souls and possesses Innate Full Soul Power. Chen Xin guides her swordsmanship through regular iron-sword practice, with the routine sufficiently measured to reassure Xu Xiao and Zhong Ling. 353

Xu Xiao subsequently encourages Yuansha to investigate whether her weapon and beast martial souls can form a Self Martial Soul Fusion Skill and plans a specialized cultivation program for her. This possibility remains an avenue for experimentation rather than an established ability. 357
