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

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

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

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
• 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

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
• 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 — renamed first soul skill; used against Chen Jianjun alongside the Divine Slaughter's Domain. 37 156
• Heart Sever / Heartless Severing — renamed second soul skill; follows Void Sever in rapid combinations. 37 156
• Grief Sever / Sorrowful Severing — renamed third soul skill; part of his successive sword-strike barrage. 37 156
• Emotion Severing — fourth soul skill, used against Chen Jianjun. 156
• Law Severing — fifth soul skill listed among his upgraded techniques. 156
• Seven Kill True Body — seventh soul skill, invoked during his duel with Chen Jianjun. 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

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
• 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

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

Relationships

• Xu Xiao — Eldest sworn brother and mentor. Xu Xiao arranges Chen Xin's training, guides him toward an independent sword path, and earns his lasting trust. 20 21 28
• 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. 19 20
• 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. 42 43 127 130
• 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. Chen Xin impulsively misreads her arrival and attempts to carry out the group’s supposed “tradition.” 55
