Power Progression

Stage / Realm / Level	Chapter	Notes
Level 96	30	Demonstrates precise Soul Pressure control while helping Tang Xuan fuse with the Mysterious Wing Soul Bone.
Touched Level 97 opportunity	1	Tang Xuan's statement, “A heavy sword has no edge; great skill is unadorned,” causes his aura to become fully restrained; Chen Xin estimates a true breakthrough would require five to ten years.
Level 98, mid-stage	41	Absorbs the Primal Chaos Immortal Herb, which greatly increases and compresses his Soul Power.
Condensed Nine Rings	251	Permanently condenses all nine Soul Rings into a single red-and-blue gem on the Seven Kill Sword's guard; gains one Soul Skill containing the combined power and age of all nine original skills.

Background / History

Chen Xin saved and adopted Tang Xuan, raising him with the affection of a biological grandfather. Tang Xuan considers him his only true grandfather and rejects the Clear Sky Sect as family in favor of Chen Xin and the Seven Treasure Glazed Tile Sect. 1 2

A leading figure on the sword path, Chen Xin initially teaches Tang Xuan with wooden swords and later passes on the Seven Kill Sword Art. Tang Xuan's unconventional understanding of the sword repeatedly exceeds Chen Xin's expectations: he reaches the threshold of Return to Simplicity and comprehends Sword Momentum at extraordinary speed. 2 4 5 6

After witnessing Tang Xuan create the Clumsy Intent Sword Art, Chen Xin recognizes that he is no longer qualified to serve as Tang Xuan's swordsmanship teacher. He instead accepts Tang Xuan as his grand-disciple and continues to support his cultivation. 5 6

Tang Xuan later gives Chen Xin the Primal Chaos Immortal Herb, allowing him to reach Level 98 mid-stage. 41 He continues pursuing the final Level 99 threshold through seclusion, Soul Bone absorption, refinement of his Soul Rings, and combat. 250 251 269 355

Appearance

Chen Xin is an elderly man with white hair and a youthful face. He commonly wears blue robes and carries a blue longsword; his otherwise calm eyes can reveal intense killing intent. 282

• Delicate, baby-like face and a typically cold expression. 1
• White hair despite a youthful complexion. 250 282
• Uses a plain azure Seven Kill Sword. 250 282
• His aura can be completely concealed, making him seem like an ordinary old man. 1

Personality

Chen Xin is deeply protective of Tang Xuan and Ning Rongrong, treating both as family. He secretly guards Tang Xuan during training, enrollment at Heaven Dou Royal Academy, and dangerous encounters with hostile Soul Masters. 3 10 21 22

In battle, he is cold, decisive, and fiercely aggressive. His protective instincts can override restraint when Tang Xuan is threatened, though he ultimately respects Tang Xuan's judgment in matters of strategy and mercy. 21 211 258

As a swordsman, Chen Xin values enlightenment and self-discovery. He guides Tang Xuan toward understanding his own Sword Heart rather than forcing him to follow the Seven Kill Sword Art's path. 5 212 332

• Ning Rongrong — cherished junior whom he protects and gifts with a wooden sword pendant. 3 6
• Ning Fengzhi — fellow Seven Treasure Glazed Tile Sect leader and trusted collaborator; Chen Xin's displeasure is significant enough to immediately halt Ning Fengzhi's calculations regarding Tang Xuan. 1 90
