Background and History

Seven Treasure Glazed Tile Sect

Chen Xin is Chen Lang’s only grandfather and his most steadfast supporter. When Chen Lang spent three years publicly slacking off despite awakening Innate Full Soul Power and the Seven Kill Sword, Chen Xin endured criticism from Ning Fengzhi, Bone Douluo, and the sect rather than force his grandson to cultivate. 1 2 3

He trusted Chen Lang’s promise that he would eventually make him proud. When Ning Rongrong publicly broke off her engagement with Chen Lang, Chen Xin personally prepared several soul beasts for his grandson’s ring absorption and defended him against Bone Douluo’s doubts. 3 4

Restoring the Sword Heart

Chen Xin had remained at level 96 for a long time because his once-uncompromising Sword Heart had become restrained by concern for his family. Chen Lang’s explanation of the Seven Kill Sword’s offensive path stirred Chen Xin’s dormant killing intent and loosened his bottleneck. 20 23 24

When Chen Xin nearly suffered deviation while attempting his breakthrough, the Seven Kill Swords of grandfather and grandson resonated. Chen Lang entered Chen Xin’s inner conflict and urged him to abandon hesitation; Chen Xin subsequently reached level 97 and awakened the second form of the Seven Kill Sword. 24

Challenges and Seclusion

After Chen Lang began cultivating at the Ice and Fire Yin Yang Well, Chen Xin spent roughly a year and a half challenging Titled Douluo above level 95. He gained insights through both victories and defeats, accepted a basket of challenge letters on Chen Lang’s behalf, and concealed an injury from his grandson before entering seclusion. 35 36

Three years later, Chen Xin emerged from the Sword Tomb as a level 98 Titled Douluo. He survived the Heart Demon of the Killing Path by transforming its accumulated malice into blood-red sword energy and absorbing it with the Seven Kill Sword. 85

Star Dou Great Forest Expedition

Chen Xin accompanied Chen Lang into the Star Dou Great Forest to hunt Xiong Jun, a Darkgold Dreadclaw Bear with more than 400,000 years of cultivation. He confronted the beast directly, shielding Chen Lang during their coordinated assault. 99 102

After Chen Lang was injured by Xiong Jun, Chen Xin unleashed his self-created ultimate technique, Man-Sword Unity, and split the bear in two. The technique consumed nearly half of his Soul Power. 103 104

When the Myriad Monster King attacked Chen Lang during his absorption of Xiong Jun’s soul ring, Chen Xin stood guard despite his depleted condition. The plant-type ferocious beast later overwhelmed him, the Titan Giant Ape, and the Sky Azure Bull Python before Chen Lang intervened. 104 106

Pursuit of Rank 99

Although proud of Chen Lang’s ability to protect himself, Chen Xin considers his own strength insufficient. He seeks Qian Daoliu’s advice on reaching level 99 and plans to search for an opportunity beyond the continent, eventually departing for travels at sea. 107 116 179

Appearance

Chen Xin is an elderly swordsman whose presence becomes increasingly restrained and weighty after his level 98 breakthrough. He is seen in snow-white attire with silver-white hair, carrying the imposing Seven Kill Sword. 85 89

• Silver-white hair. 85
• Often wears white or snow-white robes. 89
• His evolved sword bears a crimson pattern within its formerly crystalline-blue blade. 85
• His level 98 aura is described as contained rather than outwardly domineering, yet carries a sharper edge than before. 85

Personality

Chen Xin is deeply protective of Chen Lang and consistently places his grandson’s safety above his own condition or reputation. He bears sect-wide pressure during Chen Lang’s apparent laziness, secretly watches over him, and immediately intervenes when others threaten or insult him. 1 16 91

He is proud, competitive, and unwilling to show weakness. He hid injuries sustained during his challenges, was embarrassed that Chen Lang witnessed his near-deviation, and continued seeking greater strength even after reaching level 98. 24 36 91 116

His greatest internal flaw was hesitation born from familial attachment. Overcoming it did not make him less caring; instead, he reconciled his protectiveness with the Seven Kill Sword’s decisive path of slaughter. 23 24 85

Abilities & Skills

Seven Kill Sword Martial Soul

Chen Xin wields the Seven Kill Sword, an offensive Martial Soul associated with a path of unhesitating killing intent.

• Its initial form is a massive ancient greatsword. 5 24
• Upon reaching level 97, it evolves into a crystalline-blue giant sword. 24
• After surviving the Heart Demon of the Killing Path at level 98, it becomes the Blood-Patterned Seven Kill, with crimson patterns fused into its blade. 85
• Chen Xin and Chen Lang’s matching Seven Kill Swords can resonate, allowing Chen Lang to perceive Chen Xin’s internal struggle during his breakthrough. 24

Supreme Sword Intent

Chen Xin’s sword intent is fueled by the Seven Kill Sword’s killing path and his own lifelong battle experience.

• He fought numerous Titled Douluo above level 95 to gain insight for his breakthrough. 36
• His red sword energy can cut into Xiong Jun’s Darkgold Dreadclaw Bear body despite its exceptional defenses. 103
• The Heart Demon of the Killing Path initially endangered him, as it was formed from the malice and killing intent accumulated through countless past slayings. 85

Sword Net Across the Sky

Sword Net Across the Sky is the Seven Kill Sword’s second style.

• Chen Xin condenses dense golden sword energy into a defensive sword net. 102
• The technique can intercept and clash with Xiong Jun’s massive claw shadows. 102

Man-Sword Unity

Man-Sword Unity is Chen Xin’s self-created ultimate technique, merging his Soul Power, sword energy, killing intent, and Martial Soul into a single overwhelming strike. 103

• It manifests seven blood-red characters: Kill, Break, Shatter, Absolute, Destroy, Crush, and Mourn. 103
• Chen Xin becomes one with the Seven Kill Sword and forms a colossal descending sword shadow. 103
• The technique destroyed Xiong Jun’s claws and Darkgold Bone Armor before cleaving the 400,000-year soul beast in half. 103 104
• Its cost is severe, consuming nearly half of Chen Xin’s Soul Power and leaving him pale afterward. 104

Relationships

• Chen Lang — His only grandson. Chen Xin trusts, spoils, protects, and takes immense pride in him; Chen Lang in turn helps restore Chen Xin’s Sword Heart and worries over his injuries. 1 24 36 91
