Background

Chen Xin is one of the Seven Treasure Glazed Tile Sect's two Supreme Elders, alongside Gu Rong. He and the older generation of the sect fought the Martial Soul Hall; his father was killed by Qian Daoliu during those conflicts. The loss left Chen Xin focused excessively on Soul Power and lacking absolute confidence in his Sword Dao, preventing him from advancing beyond level 96 for many years. 31 44

The Black Jade Divine Bamboo deepened the Seven Kill Sword's potential rather than directly raising his Soul Power. Its refinement helped Chen Xin recognize the importance of his Sword Dao and set him on the path toward a later breakthrough. 44

After Xu Yang entered Slaughter City against his wishes, Chen Xin spent nearly two years consumed by self-blame and regret. He repeatedly practiced the sword to cut through these emotions, ultimately transforming his state of mind when Xu Yang returned alive; this realization advanced him to level 98. 97 110

Personality

Chen Xin is stern, disciplined, and intensely protective of the Seven Treasure Glazed Tile Sect and its younger members. He opposed Xu Yang's entry into Slaughter City because he understood its dangers, then blamed himself for not stopping him. 97 110

As a mentor, he favors harsh practical instruction over gentle explanation. He seals Xu Yang's Martial Soul, removes his storage tools, forces him to survive independently, and uses real combat to correct Xu Yang's hesitation and past-life mentality. 94 96

Despite his severity, he is attentive and caring. He personally caught thousand-year Soul Beasts to replenish Xu Yang after his return from Slaughter City, taught him how to control Killing Intent, and later left Golden Crow Soul Bones for him. 110 111 154

Appearance

Chen Xin is associated with the sharp, oppressive aura of the Seven Kill Sword. Following his breakthrough in state of mind, that aura became notably restrained, making him feel increasingly like an ordinary Soul Master despite his power. 110 111

• Wields the Seven Kill Sword Martial Soul.
• His Sword Intent can produce a prickling sensation on Xu Yang's skin even before Chen Xin is approached. 151
• His Sword Intent eventually reaches the threshold of tangible, materialized form. 151

Story Role / Major Arcs

Xu Yang's Training

Ning Fengzhi assigns Chen Xin to train Xu Yang after concerns arise over Xu Yang's mental state following his battle with Fallen. Chen Xin seals Xu Yang's Martial Soul and takes him on a survival-and-combat journey to teach the Seven Kill Swordplay and reshape his combat mentality. 93 94

Chen Xin arranges increasingly dangerous real battles, beginning with thirty Wolf Bandits and their Wolf King. Over two years, he guides Xu Yang through battles against bandits, Fallen, Soul Beasts, and Soul Masters until Xu Yang discards his past-life mindset and comprehends Blade Intent. 94 96

Slaughter City Aftermath

Chen Xin unsuccessfully tries to stop Xu Yang from entering Slaughter City, then spends two years regretting his failure as a mentor. Xu Yang's return resolves this emotional burden and pushes Chen Xin to level 98; afterward, Chen Xin promises to teach Xu Yang to control his solidified Killing Intent. 97 110

Conflict with Spirit Hall

Chen Xin intervenes when Bibi Dong threatens Xu Yang in Spirit City. Amplified by Ning Fengzhi, he overwhelms Black Leopard Douluo, Demon Bear Douluo, and Ghost Douluo, completes the Nine Kill Sword, and battles Qian Daoliu. 143 145

He continues defending Xu Yang during later clashes with Spirit Hall, including the confrontation involving Golden Crocodile and Qian Renxue. 173 174

Golden Crow Hunt

Chen Xin accompanies Xu Yang to hunt the two-hundred-thousand-year Golden Crow. He pursues the Ferocious Beast Golden Crow using his Spirit Avatar, severely wounds it with Quake the Four Directions, and remains with Xu Yang during the Soul Ring absorption. 151 152 153 154

After witnessing Xu Yang's Sun Spirit Avatar and Pure White World, Chen Xin recognizes him as an equal in combat. Their spar demonstrates both Chen Xin's God Demon Dual Slash and Xu Yang's ability to resist it. 155 156

Sun Moon Continent

With Bibi Dong approaching godhood, Chen Xin travels ahead to the Sun Moon Continent to establish a refuge for the Seven Treasure Glazed Tile Sect. 191

Upon arriving in Yue Kingdom, he seizes control of the nation within two hours and installs a Level Nine Space Teleportation Soul Tool in its Imperial Palace, enabling the sect's forces to relocate. 192
